Effect of Feeding Intervention on Reproductive Performance of crossbred Cows in different Seasons of Bangladesh

Effect of Feeding Intervention on Reproductive Performance of crossbred Cows in different Seasons of Bangladesh

The study was undertaken to investigate the reproductive performance of crossbred cows raised at farm conditions in Bangladesh through nutritional intervention during the last trimester of pregnancy in different seasons of a year. Feeding intervention in monsoon consists of feeding urea molasses straw (UMS) instead of only rice straw with increased concentrate level. This resulted in increased total DM intake from 8.07 to 9.26 kg/d, DCP intake from 0.23 to 0.60 kg/d and ME intake from 54.57 to 75.92 MJ/d in crossbred cows. Feeding intervention decreased postpartum estrus period from 91.72 to 84.02 d, calving to conception interval from 104.45 to 95.89 d and increased calf birth weight from 21.54 to 22.94 kg, irrespective of breed type. Breed had also similar effect on these reproductive parameters irrespective of feeding type. In winter, legume forage supply was curtailed over that supplied traditionally and rice straw with concentrates was increased resulting in decreased total DM, DCP and ME intake of cows. Intervened feeding, irrespective of genotype of the cows, decreased postpartum estrus period from 88.42 to 83.72 d, calving to conception interval from 99.52 to 92.56 d, service per conception from 1.56 to 1.39 number and increased calf birth weight from 21.77 to 23.42 kg. Breed also affected the reproductive performance irrespective of feeding intervention. Feeding intervention in summer season was to reduce rice straw and concentrates, and to increase the supply of green grass to the cows. Intervened feeding resulted in pronounced increase in intake of all the nutrients as well as the feed cost. As in the case of winter, both feeding and genotype had significant effects on postpartum estrus period, calving to conception interval, service per conception and calf birth weight, when considered individually. From the results of the present study it may be concluded that feeding interventions have significant effect on reproductive performance of crossbred cows.

Comparative Productive And Reproductive Performance Of Holstein Friesian And Jersey Crossbred Cows In Humid Sub-Tropics Of Chitwan Under Farmer’s Managed Condition

Comparative Productive And Reproductive Performance Of Holstein Friesian And Jersey Crossbred Cows In Humid Sub-Tropics Of Chitwan Under Farmer’s Managed Condition

The objective of this study was to compare the productive and reproductive parameters of two genotypes (Holstein Friesian and Jersey crossbred cattle) in Chitwan district under farmers managed condition. Data on productive and reproductive traits like Milk yield in current lactation (LMY), Annual milk yield (AMY), Lactation length (LL) Age at first calving (AFC), Gestation length (GL), and Dry period (DP) were collected from 303 crossbred cows (131 Holstein crossbred and 172 Jersey crossbred) from households, smallholder’s farms and commercial farms of Chitwan during the month of November 2014 to April 2015. Data collected were cleaned, coded, entered into MS-Excel and analyzed by using SPSS 16.0 software version. Results indicated that Milk yield in current lactation and Annual milk yield were significantly (p<0.05) affected by breed. That means milk yield in current lactation (3562.00±134.39 ltr.) and annual milk yield (3500±123.96 ltr.) were observed highest in Holstein crossbred cows as compared to Jersey crossbred cows. However, Lactation length, Age at first calving (AFC), Gestation length (GL) and Dry period (DP) were not affected by breed (p>0.05). The tendency of highest Lactation length (LL) (309.20±3.66 days), Gestation Length (GL) (297.60±8.93 days) and Dry period (DP) (72.74±9.78 days) were recorded in the Holstein crossbred cows whereas Age at First calving (AFC) (918.70±20.42) was comparatively higher in Jersey crossbred cows. Roughly similar feeding and managerial practices including short duration of study period during humid sub-tropics condition indirectly affected the findings of this study and need to perform the same task including more number of animals for a longer period of time for better output before recommendation.

Immunological attributes of blood and milk neutrophils isolated from crossbred cows during different physiological conditions

Immunological attributes of blood and milk neutrophils isolated from crossbred cows during different physiological conditions

ABSTRACT: The goal of this work was to understand how polymorphonuclear leukocytes (PMN), the first line of cellular defence, integrate and prioritize multiple chemotactic signals to navigate during periods of demand like subclinical mastitis (SCM), clinical mastitis (CM), pregnancy (P), and calving (C). For this, blood and milk samples were collected from five groups of crossbred cows (healthy, with SCM, CM, pregnant, and newly calved). Maximum viability was seen in the PMN of healthy cows, whereas minimum viability was observed in CM cows. Phagocytic activity (PA) of blood and milk PMN decreased significantly (P < 0.05) at C and in CM cows. Chemotactic activity of blood PMN was minimum in C followed by CM, SCM, and P cows. PA was found to be negatively correlated with the plasma cortisol levels and inverse relationship was observed between the plasma interleukin-8 (IL-8) levels and the chemotactic activity of neutrophils. There was a significantly (P < 0.05) higher expression of CXCR1 and IL-8 on both blood and milk PMN of CM cows followed by C and SCM cows. Minimum expression of selectin (CD-62L) was seen on blood PMN isolated around calving, whereas maximum expression of integrin (CD-11b) was in CM cows. Healthy and P cows showed the highest expression of CD-62L on blood PMN but its expression remained unaltered in milk PMN. Irrespective of physiological stage of the cows, immune suppression was found to be always cortisol dependent. Observing the neutrophil activity and mRNA expression of genes isolated from cow neutrophils can be used as indicators to assess the health/physiological status promptly for immediate therapeutic or management-related actions.

Article: Evaluation of productive and reproductive performances of local and crossbred cows in Manikgonj district of Bangladesh

Article: Evaluation of productive and reproductive performances of local and crossbred cows in Manikgonj district of Bangladesh

Abstract: A total of 90 lactating cows from twelve dairy farms were used to conduct this study in order to evaluate the productive and reproductive performance of crossbred and local cows at farmer’s level in Manikgong district. All cows were divided into three groups, according to their genetic composition as Local, Local x Friesian and Local x Friesian x Friesian cows. The results showed late sexual maturity (37.41±0.03 months), calving interval (481.86±0.33 days), shortest lactation period (198.46±2.36 days) and lowest average milk production (2.25±0.04 L/day) in local cows. On the contrary, longest lactation period (266.43±1.18 days) and highest average milk production (7.45±0.11 L/day) were observed in LFF cows, whereas early sexual maturity (30.58±0.02 months) was found in Local x Friesian cows. From the above perspective it could be concluded that LFF crossbred cows may be suitable for profitable dairy farming in Bangladesh but herd life and life time productivity is one of the most influential factor for profitable dairy farming. However, further study with larger sample sizes covering more different management systems would be required to describe a better inference in this consideration.

Effect of estradiol and cloprostenol combination therapy on expulsion of mummified fetus and subsequent fertility in four crossbred cows

Effect of estradiol and cloprostenol combination therapy on expulsion of mummified fetus and subsequent fertility in four crossbred cows

Four crossbred cows with mummified fetus were utilized for the study. The cows were subjected to gynecological examination and based on the findings the cases were diagnosed as mummified fetus. The cows were treated with 2 mg estradiol valerate and 500 µg cloprostenol and were examined every 12 hr after 24 hr of the treatment for cervical dilatation and other signs related to fetal expulsion. The time duration between treatment and starting of cervical dilatation ranged from 48 to 58h (53.00 ± 2.08 hr). Complete dilatation of cervix was observed after 70.00 ± 2.94 hr post treatment (Range = 64-76 hr). The mean fetal crown-rump length (CRL) was 31.5 cm, which ranged from 27.5 to 38 cm. The number of cotyledons in pregnant horn also showed wide variation (Range 24-38 numbers) with mean ± SE of 30.3 ± 3.07 numbers. In the placenta of three animals irregular shaped large adventitious cotyledons were observed in the inter-cotyledonary areas. Out of the four animals treated, three animals were conceived within three estrous cycles and one animal had cystic ovary in the next cycle and was not conceived even after four cycles. It was concluded that the estradiol and prostaglandin F 2 α

Effect of Feeding Intervention on Milk Production Performance of Crossbred Cows in Different Seasons of Bangladesh

Effect of Feeding Intervention on Milk Production Performance of Crossbred Cows in Different Seasons of Bangladesh

Total milk yield did not increase due to feeding intervention in winter season which might be expected that the amounts of legume forage was significantly reduced in the intervention feeding compared to that in the traditional feeding. Meanwhile, milk yield was not reduced which might be due to the fact that the nutrient supply still met the requirement of the animals of intervention group. Although farmers are not getting benefits instantly from increased milk yield due to feeding intervention but they are saving forages for future feeding which can increase milk yield in the forage scarcity period resulting in increased income. The significant variation among the mean values for milk yield of different crossbred cows fed on two different diets (Table 3) indicated that the differences in the dietary regimes of the present study had no significant effect on milk yield of genotypes of cows. Despite the significant (P<0.05) reduction in legume forage supply in intervention feeding group compared to traditional feeding group, milk yield of the animals of the two feeding groups remained similar. The reason could be due to supplied in much higher amounts nutrients in intervened group than the requirements of the animals. From the results it also appeared that it happened to each of the genotypes under study further indicating that within each genotype the difference in dietary regime had no significant effect on milk yield of cows.

lactation length was similar. Total yields from FxJ cows were similar to those in industry (LIC & DairyNZ 2011). This likely reflects that the FxJ records in the dairy statistics are obtained from progeny-test herds, as are those in this study, while the F and J records include those from the wider industry as well as the progeny- test herds. The F cows had greater MY than J or FxJ cows. While this was not associated with greater FY or PY there was a greater WMP and SMP yield.

A COMPARATIVE STUDY ON SOME BIOLOGICAL CONSTITUENTS IN SERUM DURING NORMAL AND SUB OESTROUS CYCLES OF CROSSBRED COWS OF ASSAM

A COMPARATIVE STUDY ON SOME BIOLOGICAL CONSTITUENTS IN SERUM DURING NORMAL AND SUB OESTROUS CYCLES OF CROSSBRED COWS OF ASSAM

Sub-oestrus condition is known to be one of the major reproductive problems resulting failure of breeding at right time contributing great economic loss to the dairy farmers who are maintaining crossbred cattle while high yielding traits of crossbred cattle might be one of the stress factors leading to this problem ( Schmidt et al., 1989 ). Influence of minerals on certain enzymic system having impact on reproductivity where some major and minor elements may play major role in mettaenzymic reaction and imbalance or deficiency of these elements leading to many reproductive problems when some biological constituents play pivotal role for reestablishment of ovarian function and subsequent occurrence of oeatrus at appropriate time (Vallee, 1971; Hidiroglou, 1979; Mayarnard et al. 1979). Comparative information on serum biological constituents during the period of normal and sub-oestrous cycles of crossbred cattle under the prevailing condition of Asom appeared to be limited. Therefore, the present study was carried out to elucidate difference of different biological constituents in serum if any at different days of normal and sub-oestrous cycles of crossbred cattle of Assam.

Days to calving and intercalving interval in beef and dairy beef crossbred cows

Days to calving and intercalving interval in beef and dairy beef crossbred cows

One important attribute of a beef-breeding cow is the ability to wean a calf every year. Furthermore, an earlier- born calf is likely to be heavier at weaning and its dam has more opportunity to conceive again during the following breeding season. In a spring-calving system under the seasonal pastoral-grazing system in New Zealand, a 365- day intercalving interval is desirable. A normal gestation length is 280 days leaving 85 days for a cow to resume oestrous cycles and conceive again to maintain the 365- day calving interval. Literature estimates of the interval between calving and the first oestrous cycle post-calving are 53-82 days for mixed-aged beef-breeding cows and 81-95 days for first-lactation beef-breeding cows (Hickson et al. 2012; Knight & Nicoll 1978; Morris et al. 1978; Smeaton et al. 1986), indicating that a 365-day calving interval is difficult to maintain.

Assessment of Hematobiochemical Profile of
Postpartum Crossbred Anestrous Cows
Compared with the Cyclic Cows

Assessment of Hematobiochemical Profile of Postpartum Crossbred Anestrous Cows Compared with the Cyclic Cows

Hemato-biochemical parameters are the key features of good physiological condition, where good physiological condition is the precursor of good production. For this reason the present study was aimed to assess the mean values of different hematological and biochemical profile of postpartum crossbred anestrous cows and determining differences among the mean values of different hematological and biochemical profile between cyclic and postpartum crossbred anestrous cows in the study areas. The study population was 30 crossbred cows. The animals were sampled purposively and divided into two groups. Group A which is the target group was suffering from post-partum anestrous of more than 90 days and group B which is the control group was cycling cows of crossbreed. Blood samples from cows with anestrous and cyclic were collected for hematological, bi- ochemical and hormonal status analysis. T-test was performed to check the mean and standard error where confidence interval was 95%. All the analysis was performed at the 0.05 significance level. The Erythrocyte Sedimentation Rate was not significantly lower and Hemoglobin percentage was significantly higher in anestrous cows than normal cy- cling control cows.

significant (P<0. 01) among the treatments. This result was comparable with the 3.1% BW intake reported by [27] and higher than the values (2.2 – 2.3%) reported by [28]. Daily DM intake of 3.32 kg/d for urea treated rice straw supplemented with Veranostylo [29] and 2.46 kg/100 kg BW for treated rice straw were reported by [29]. The total DM intake (g/kg W 0.75 ) was highly significant (P<0.001) among the treatments and this result was comparable with that reported by [30] who noted 147 g/kg W 0.75 for lactating crossbred cows fed rations containing calcium salts of palm oil fatty acids (bypass fat). As well 113.2 and 122.1 of DM intake (g/kg W 0.75 ) was reported by [31]. The observed variations among the studies emanated from the differences in the quality of the feed used, animal factors (age, physiological status of the animals and breed), rumen fill, rate of passage of particulate matter and rates of degradation of experimental feeds used. Increased organic matter intake (P<0.001) when cows were fed with basal diet consisting Pennisetum Purpureum Silage might be due to the increased total DM and CP intake.

Effect Of Supplementation With Different Proportions Of Breweries Dried Grain And Maize Bran Mixtures On The Performance Of Crossbred Dairy Cows

Effect Of Supplementation With Different Proportions Of Breweries Dried Grain And Maize Bran Mixtures On The Performance Of Crossbred Dairy Cows

It can be judged from the present study that the different proportion of concentrate mixture used in the current study contained sufficient amount of energy and protein feeds above the level recommended in ARC (1990), and sufficient enough to support the projected milk yield (8-10 kg/d). Therefore, it can be concluded that supplementing low quality basal diets with breweries dried grain and maize bran could be alternative sources of dairy feed supplements to provide adequate and required amount of protein and ME for dairy animals. Thus, it can be concluded that the different proportion of breweries dried grain and maize bran mixtures in the present study have a potential to replace the concentrate mix (T1) without significant reduction in milk yield of lactating crossbred cows fed a basal diet of natural pasture hay and able to support the observed milk yield (10.33 kg/d).

further divided into two groups of 8 cows each and were fed either a control diet consisting of forage and concentrate or the control diet plus UMMB as a supplement. Cows were in their second and third lactation. The study was carried out at Andassa Livestock Research Center (ALRC), Amhara Region, Ethiopia. ALRC is located at 11 0 29´N latitude, 37 0 29´ E longitude, at an altitude of 1730 meter above sea level. The annual average rainfall at the center is 1150 mm and the mean minimum and maximum temperatures during the experiments were 9 and 34 0 C, respectively (December- May). This experiment was conducted during the dry period using late stage of lactation cows of both breeds. The four treatments used for both the experiments were Fogera cows fed the traditional diet as a control (FN), Fogera cows fed the control diet plus UMMB as experimental group FS, crossbred cows fed the control diet (CN) and crossbred cows fed the control diet plus UMMB as experimental group CS. Apart from the nutrient supply and stage of lactation, the experimental design and management were similar to the experiment which was conducted using similar breed, number of cows and similar intervention diet (Tekeba et al., 2013) in which cows remaining in the same treatment. The dietary energy and protein levels were adjusted based on the milk yield and change in body condition of the two breeds during the first experiment. Accordingly, 35 and 40 MJ ME with 380 and 517 g CP were planned to be supplied to Fogera cows in the control (FN) and the supplemented group (FS), respectively. The crossbred cows were offered 47 and 54 MJ ME with 546 and 738 g CP for the control (CN) and supplemented group (CS), respectively.

Article: Effect of heat stress on milk production and its composition of Holstein Friesian crossbred dairy cows

Abstract: The aim of this research was to observe the effect of heat stress on milk yield and milk compositions of Holstein Friesian crossbred (HF) dairy cows. To fulfill the objectives, a total of 9 Holstein Friesian crossbred cows were selected for this study. Green grasses (German, Para) were supplied adlibitum and concentrate feeds (mixture of wheat bran, rice polish, mustard oil cake, di-calcium phosphate and salt) were supplied at the rate of 2.0 kg/day/cow. Management practices for all the cows were similar following the BAU Dairy farm practices. Data were collected on milk yield (l/h/d), relative humidity (%) and barn temperature ( 0 C). The obtained temperature humidity index (THI) of July, August, September and October were 84.95, 81.99, 81.40 and 79.57, respectively. The highest THI was found in July which indicated higher heat stress during this month. A significant difference (p<0.05) in milk yield of cows was found among different months of July to October. The highest milk yield (6.10±0.50 l/h/d) was found in October among observed months. The compositions of milk such as total solids (TS), solids-not-fat (SNF), fat, protein, lactose, and ash also differed significantly (p<0.01). The highest values (%) of TS, SNF, fat, protein, lactose and ash content of milk were found in October as 12.63, 8.80, 3.83, 3.69, 4.39 and 0.72, respectively and lowest values (%) were in July as 12.20, 8.50, 3.71, 3.50, 4.30 and 0.69, respectively due to the high THI value. From these results, it is concluded that heat stress has strong effect on milk yield and milk composition of HF cows in Bangladesh. Management strategies are needed to minimize heat stress and attain optimal dairy animal performance.

“PHARMACOKINETICS OF LEVOFLOXACIN IN CROSSBRED COW CALVES FOLLOWING INTRAMUSCULAR ADMINISTRATION”

“PHARMACOKINETICS OF LEVOFLOXACIN IN CROSSBRED COW CALVES FOLLOWING INTRAMUSCULAR ADMINISTRATION”

Pharmacokinetic study of levofloxacin was carried out in six crossbred cow calves of 9-12 months of age weighing 70-90 kg. Levofloxacin was given intramuscularly at the dose rate of 4 mg/kg body weight in six crossbred cow calves. Levofloxacin concentration was estimated at different intervals (0.042 to 24 h) by microbiological assay method using E. coli (ATCC 25922) as test organism. Kinetic parameters were calculated by using one compartment open models. Attempts were made to calculate the rational dosage regimens of levofloxacin on the basis of kinetic data and maintenance of therapeutic concentrations in plasma. Following intramuscular administration of levofloxacin, the peak plasma concentrations of levofloxacin (12.25 µg/ml) was observed at 1 h. The elimination half- life (t 1/2 β), mean residence time

Lameness in dairy Cows

Lameness in dairy Cows

feature of parturition is the decrease in the rate of rumination shown by all cows. This reduced rumination combined with the marked increase in concentrate feeding which occurs at the time of calving leads to an increased risk of rumen acidosis. Rumen acidosis has been linked to coriosis (laminitis), leading to an even greater increased fragility of the corium. The problem is compounded by rations that are low in long fiber 10,25,26 . Rumen acidosis also leads to depressed biotin synthesis, and lack of biotin further exacerbates poor horn formation, especially of the white line cement 15 . In one UK trial, supplementation with 20 mg/day of biotin lead to a 50% reduction in lameness caused by white line disease. No effect was seen until after 120 days of supplementation, this being the period that it takes for the white line cement to reach the weight- bearing surface of the sole 15 . The risk of white line disease increases with increasing parity, and for cows in their third lactation and above, biotin decreased the incidence of white line lameness by a factor of three 2,10,11 . Many rations are now supplemented with biotin, although clearly the best preventive measure is to avoid the development of periparturient rumen acidosis. The desire to incorporate high levels of forages in dairy rations will likely to continue because they offer the potential for delivering high nutrient densities while optimizing rumen health. Production of quality forage/silage is dependent up on the management decisions and practices implemented before, during and after the harvest/ensiling period. Once crops have been harvested, monitoring for nutrients density, nutrient availability and the presence of toxins and troublesome silage volatile fatty acids can help alleviate off-feed and rumenal acidosis issues that can predispose hoof health problems 27 .

Effect of Garlic (Allium Sativum) Supplementation on the Growth Performance of Crossbred Calves

Effect of Garlic (Allium Sativum) Supplementation on the Growth Performance of Crossbred Calves

Antioxidants in garlic extract such as the organosulphur compound, protect against oxidative damage there by reduced the risk of injury to vital molecules and prevented the onset and progression of diseases (Gutteridge, 1993). Supplementation of Ruchamax, herbal based product containing garlic as a major ingredient increased the digestibility of rations specially roughage and crude fiber (Pradhan and Bishwas, 1994). Supplementation of garlic extract resulted in proper maintenance of liver function because it has an important protective role against liver toxicity caused by a variety of medicinal and environmental substances (Borek, 2001). Kongmun et al. (2011) studied the influence of supplementation of seven per cent coconut oil plus 100 g of garlic powder on rumen fermentation and ecology of swamp buffaloes. They observed coconut oil and garlic supplementation improved the rumen ecology and reduced the methane gas production by nine per cent without changing nutrient digestibility. Garlic supplementation through feed, in particular, has many favourable experimental and clinical effects, which include stimulation of immune function, enhanced foreign compound detoxification, and restoration of physical strength and resistance to various stresses (Amagase et al., 2001). Considering the above facts the present study has been conducted to study the influence of garlic supplementation on the growth performance of crossbred calves and to study the effect of garlic supplementation on the health status of crossbred calves.
