the aim of this study was to investigate the association of bovine leukocyte antigen-drb3 alleles with peripheral blood mononuclear cell (pbmc) proliferation in response to staphylococcus aureus. the animals included in this study (n=347) were approximately of same age and comprised of f2 holstein-friesian ´ charolais (n = 155), holstein-friesian backcross (f0 holstein-friesian dams crossed wit...

potential relationships between amino acid motifs in the antigen binding groove of various alleles of the bovine major histocompatibility complex dr (bola-dr) molecule and peripheral blood mononuclear cell (pbmc) proliferation, in response to s. aureus and phytohemaglutinin, were investigated. the animals included in the study were approximately of the same age and comprised of pure holstein-fr...

Intake and annual performance of Limousin × Holstein-Friesian and Simmental × Holstein-Friesian beef suckler cows, and pre-weaning growth of their calves Beef cross dairy heifers remain a significant source of replacement breeding stock for the suckler herd in Ireland. Previous studies at this centre have compared Hereford × Friesian beef suckler dams with Charolais × Friesian and Limousin × Fr...

Yak are crossed with Bos taurus and Bos indicus cattle, including common local cattle breeds (via natural service) and via artificial insemination of frozen-thawed semen from improved breeds (e.g. Holstein Friesian). Female hybrids reach puberty and mate a year earlier than pure yaks. Nonpregnant F1 females usually have several estrus cycles in the same season and will generally calve every yea...

Weaning of dairy calves is an early life husbandry management practice which involves the changeover from a liquid to a solid feed based diet. The objectives of the study were to use RNA-seq technology to examine the effect of (i) breed and (ii) gradual weaning, on the whole blood mRNA transcriptome of artificially reared Holstein-Friesian and Jersey calves. The calves were gradually weaned ove...

The study was carried out in Sahiwal, Holstein Friesian, Jersey and crossbred cattle and Murrah, Bhadwari, Jaffarabadi, Nagpuri and Surti buffaloes maintained at different organized herds to work out the polymorphism at growth hormone locus and study its effect on birth weight. A 223 bp fragment of the gene was amplified and digested with Alu I restriction enzyme. Two alleles, L and V with thre...

A total of 50 adult cows each of Friesian and Jersey breed maintained at the Livestock Experiment Station Bhunikey (Pattoki) District Kasur were selected randomly for this study. Blood smears of all animals were prepared aseptically through standard procedure. The cows found positive for theileriasis were treated with Buparvaquone (Butalex) injection @ 5 ml/100 Kg b. wt. intramuscularly, while ...

The composition and physical nature of milk is very complex. The stability of milk depends upon the different constituent of milk. Determination of heat stability of milk is one of the factors that assess the stability of milk. In this study an attempt was made to measure the heat stability of milk obtained from different varieties of cows and also made an attempt to identify the different comp...

The objective of this study was to determine the inbreeding levels and to analyze the pedigree of Irish purebred populations of Charolais, Limousin, Hereford, Angus, and Simmental beef cattle, as well as the Holstein-Friesian dairy breed. Pedigree analyses included quantifying the depth of known pedigree, average generation intervals, effective population size, the effective number of founders,...

This report describes a rare case of conjoined female twin monster (Monocephalus Thoracopagus Tetrabrachius Tetrapus Dicaudatus) in a Holstein Friesian pluriparous crossbred cow.
