Reproductive cyclicity of cross-bred cattle has been reported to be reduced due to stress. This study was conducted to investigate the role of Vitamin E in combating stress. The experiment was conducted on 36 lactating dairy cows, comprising indigenous (9 Sahiwal, 9 Achai), 9 cross-bred (Sahiwal x Holstein Frisian) and 9 Holstein Frisian located at two state dairy farms. Vitamin E was supplemented in feed at a dose rate of 1000 IU/ cow/ day for 40 days. Sampling was conducted on day-zero (control), day-20 and day-40 of Vitamin E supplementation during the diestrus phase. Concentrations of SOD and GPx increased significantly (P<0.001) with Vitamin E supplementation. Breeds also varied in SOD and GPx activities (P<0.05 and P<0.001 respectively). The stress markers (plasma MDA, HSP-70 and serum cortisol) decreased significantly with Vitamin E supplementation while breeds also showed variation in these parameters (P<0.001). Progesterone concentration increased significantly (P<0.001) with Vitamin E supplementation showing significant variation (P<0.05) among breeds. Number of follicles decreased significantly with Vitamin E supplementation (P<0.01), highest in cross-bred cows indicating quality graafian follicles with supplementation. The stress markers (cortisol, HSP-70 and MDA) were positively correlated mutually while negatively with antioxidant markers. Progesterone was positively correlated with antioxidant markers. It was concluded that Holstein Frisian and crossbred cows showed more favorable response to Vitamin E supplementation in respect of expression of stress and reproductive markers suggesting regular feeding of antioxidant to these breeds for better performance.

A study was conducted at Livestock Research and Development Station, Animal Analytical Laboratory Dir Lower Khyber Pakhtunkhwa (KPK) Pakistan to document the phenotypic and Morphometric characteristic of Achai cattle. Total 18 pure Achai Cattle were selected in the study. Phenotypic characteristic were recorded visually. Majority (88.50%) of the study Achai color have reddish brown coat color with white face but those animals were also included in the study that have radish brown color with or without white spotted face, gray muzzle, radish and white eye lashes. Physical characteristic (color of coat, muzzle, face, eye lash, horns, hump, udder hooves and tail switch) were recorded visually while morpho-metric measurements (heart girth, body length, height at withers, horn length, ear length, neck length, hoof circumference and tail length) were recorded by using measuring tape and vernier caliper. Mean body, face, ear, horn, rump and tail length was 112±4.78, 42±0.502, 19±0.469, 17±0.874, 33±0.481 and 75±1.332 centimeter, respectively. Mean width of head and shoulder was 12±2.937 and 89±0.2711, respectively. Mean circumference of neck and abdominal was 68±1.03 and 168±2.159. Mean chest girth was 142±0.978 and rump height was observed 103±4.16 accordingly. The average body weight of adult Achai cow recorded was 203.81±6.17 kg. The average birth and weaning weight was recorded 13.90±0.80 and 48.0±5.00 kg, respectively. It was concluded that Achai is a small size breed of Khyber Pakhtunkhwa Pakistan having short stature, radish brown color and fully adapted to the hilly areas of the province. © Asian Network for Scientific Information, 2015.

Buffalo is an economically important dairy animal in South Asia but mostly ignored in research priorities. In this retrospective study, the effect of management practices and age of animal on the incidence of mastitis in Nili Ravi buffaloes was investigated. A total of 1,560 quarters of buffaloes (n = 390) were screened by visual examination of the udder and milk (clinical mastitis) and California mastitis test (subclinical mastitis). Household data was collected on a predesigned questionnaire and analyzed. The prevalence of subclinical mastitis, clinical mastitis, and blind quarters was 41.8, 13.6, and 9.7 %, respectively. The highest prevalence was noted in the hind quarters and left side as compared to that in the forequarters and right side. This data significantly (p < 0.05) supported the idea that larger herd size has more chances of mastitis, with the highest prevalence (40, 32, and 27 %) in the large, medium, and small herds, respectively. Stage of lactation was significantly (p < 0.01) involved in mastitis, and the highest incidence (43.3 %) was noted in early lactation. Milk production of lactating buffaloes that ranged 6–10 l/day showed a higher rate of mastitis occurrence (p < 0.05). The cleanliness condition of a farm also contributed significantly. Animal age significantly affected the incidence of mastitis. Results revealed that age of the animal has a positive correlation (R2 = 0.772) with mastitis. This study concluded that some factors alone or in combination with other factors influence significantly the occurrence of mastitis, and to minimize the infection, these factors should be considered. The outcome of the study will be valuable for policy-making for positive management practices and implementation of preventive measures. © 2014, Springer Science+Business Media Dordrecht. Source

The experiment was conducted in Livestock Research and Development Station Surezai Peshawar. Total 112 numbers of calves including 28 Nilli Ravi and 10 Azikheli buffalo, while cattle calves contained 31 achai and 41 crossed bred (HF and Sahiwal cross). Commercially available milk replacer was used for calves feeding in this experiment. After preparation milk replacer was offer for calves feeding according to the daily requirements. The birth weight was recorded soon after birth, weakly growth rate was recorded of all calves upto weaning weight. Effect of milk replacer on birth and weaning weight of different bovine breeds was significant (P<0.05). Average birth weight of Achai, Azikheli, Cross and Nili Ravi breed were 15.23±0.49, 28.70±1.00, 21.92±0.70 and 31.90±1.10 kg, respectively. Total mortality percentage was 18.75% (21Nos). Lowest percentage of mortality (0%) was found in Achai breed calves, followed by Azikheli breed calves 14%. The results showed that milk replacer is 117.39% less expensive than natural milk. © Asian Network for Scientific Information, 2012. Source
