The present study was undertaken to determine the fertility soundness of unselected bulls used for breeding based on a standard breeding soundness evaluation technique (BSE) and trans-scrotal ultrasonography (TSU). A total of 8 bulls, with the mean age of 51⁄2 years (ranged from 31⁄2 8 years) and the mean weight of 651.5kg (ranged from 480-840 kg) were evaluated. Three bulls were Friesian Sahiw...

Genetic parameters for dairy performance traits were estimated, breeding values for the traits of all breeding sires and cows were predicted and the genetic trends were estimated using the breeding values in the Central Cattle Breeding Station (CCBS). A total of 3,801 records for Bangladeshi Local, 756 records for Red Sindhi and 959 records for Sahiwal covering the period from 1961 to 1997 were...

Staphylococcus aureus has been reported as a major pathogen in dairy animals. The pathogenic potential of S. aureus isolates is attributed to a combination of extracellular factors and invasive properties that are controlled at the genomic level. In order to elucidate patterns of pathogenic genes, 346 isolates of S. aureus were recovered from Sahiwal, Karan Fries (cattles) and Murrah (buffalo) ...

Indigenous cattle not only provide milk, dung and draught power but are also a crucial part of India’s ecologicaland cultural heritage. Despite this, they facing threat extinction. Absence information regarding theirmultiple roles monetary estimates the benefits, obstructs investment for their conservation. Currentstudy attempts to assess economic value different benefits one best indigenous br...

The study was conducted to evaluate the effect of vitamin E and zinc supplementation on energy metabolites, lipid peroxidation, and milk production in peripartum Sahiwal cows. For this, thirty-two pregnant dry Sahiwal cows were selected at sixty days prepartum and divided into four groups viz control, T1, T2, and T3 of eight each. Group T1 were supplemented with zinc at 60 ppm/d/cow, group T2 w...

Cattle are the major source of food security and income for pastoral farmers in sub-Saharan Africa. However, infectious and parasitic diseases remain a major constraint to improved cattle productivity in the region. The use of animal health economics to support decision-making on cost-effective disease control options is increasingly becoming important in the developing world. Trypanotolerant i...

The present study was conducted on quality and bioactive components in milk of Kankrej Sahiwal indigenous cattle breeds at Livestock Research Station, Kodemdesar College Veterinary Animal Science, Bikaner situated hot-arid region Rajasthan. Representative samples were collected brought to the laboratory. variance analysis observed significant effect season SFA Sahiwal, revealed that total MUFA ...

The present study was designed to investigate the effect of mastitis on various components including fat percentage, protein, total solids, solid not fat, pH, specific gravity and lactose content in milk cross-bred (Holstein Friesian × Cholistani) Sahiwal cattle. A 376 samples (excluding blind nonfunctional teats) from 100 cows (50 50 sahiwal) were collected aseptically. Animals different ages,...

the study was conducted to evaluate the effect of thermal stress on expression profile of genes related to apoptosis in peripartum sahiwal cows. for this, twelve pregnant dry sahiwal cows were selected from livestock research centre at national dairy research institute, karnal. the cows were divided into two groups consisting of six sahiwal cows each. cows of group i calved during thermoneutral...
