In present study, the polymorphism at five microsatellite loci BM302, BM4505, BMS2684, CYP21 and DIK20 were investigated for finding their association with the somatic cell counts (SCC) in crossbred cattle. Total 130 animals were tested using california mastitis test (CMT) and somatic cell count (SCC) to screen animals for mastitis. Total 83 alleles were found in all five microsatellites where ...

dairy farmers have been longing for simple and economical methods of early pregnancy diagnosis. urine based biochemical and mineral assays could be one of those methods, owing to the ease of sample collection and relatively simple and economical assays involved. however, basic information on changes in urinary composition during early pregnancy in cattle is lacking. this study was designed to e...

The objectives of this study were to determine estrus behavior, interval to estrus, duration of estrus and time of ovulation of Boran, and Boran × Holstein Friesian (HF) breeds. A total of 113 cows and heifers from the two breeds were synchronized with two estrus synchronization protocols: 1) estradiol benzoate (EB) + controlled internal drug release (CIDR) + prostaglandin (PGF2α); and 2) gonad...

Breed parameters for a computer model that simulated differences in the composition of empty-body gain of beef cattle, resulting from differences in postweaning level of nutrition that are not associated with empty BW, were estimated for 17 biological types of cattle (steers from F1 crosses of 16 sire breeds [Hereford, Angus, Jersey, South Devon, Limousin, Simmental, Charolais, Red Poll, Brown ...

A series of studies were conducted to assess the effect of increasing environmental temperatures on redox status and endocrine responses in crossbred cattle under simulated conditions. In present study four non-lactating crossbred cattle were exposed to 25, 30, 35 and 40°C temperature with relative humidity of 40-50% in psychrometric chamber for 5 hours/day from 10:00 to 15:00 hours for 21 days...

Effects of ractopamine hydrochloride (RAC) supplementation on growth performance and carcass characteristics of feedlot steers differing in biological type were investigated using British, Continental crossbred, and Brahman crossbred calf-fed steers (n = 420). Steers of each type were weighed at reimplantation [British, mean BW = 375 kg (SD = 38 kg); Continental crossbred, mean BW = 379 kg (SD ...

Background: Methane emission from the ruminants is receiving global attention due to its warming potential. It imposes development of cost-effective and easily adoptable energy reduce methane emissions ruminants. Apart this, information available on methanogenic microflora their populations in Indian native cattle also very limited. In this study, normal Gir was studied using molecular methods ...

The objective of this study was to evaluate self-fed byproducts on pasture reared finishing cattle. Major effects studied were animal performance, carcass traits and fatty acid (FA) profile with specific emphasis on conjugated linoleic acid (cis-9, trans-11–18:2; CLA). Eighty-two crossbred yearling steers were utilized in a 2 × 2 factorial design with implanted and non-implanted cattle fed eith...

Leptin plays an important role in the regulation of feed intake, energy metabolism, growth and reproduction of cattle. We used the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique to screen for DNA polymorphisms of the leptin gene in 403 cattle belonging to various breeds of Bos indicus (Hariana, Sahiwal, Gir and Nimari cattle), Bos taurus (Holstein Friesi...

To study the effect of feeding lactic acid producing bacteria on the performance of cattle calves, twenty four, day old male crossbred cattle calves (Bos indicus×Bos taurus), were distributed into two groups of 12 animals each. The animals were fed on calf starter containing wheat bran and green berseem ad libitum and milk as per requirement upto 8 weeks of age. The diet of calves of Group 2 wa...
