AIM In India, dairy industries are important for the livelihood of small scale farmers and dairy owners. Tropical theileriosis, mostly affecting dairy cattle and buffaloes is a major threat to dairy and related industries. Tropical theileriosis is caused by Theileria annulata, a hemoprotozoan parasite transmitted by Ixodid ticks of Hyalomma spp. In the present study, we examined the clinical si...

INTRODUCTION Mastitis is a multifaceted disease with varied etiology, damaging the dairy economy, worldwide. Hence, the importance of timely diagnosis of this disease is represented well in saying, "A day lost is quarter lost"! Focus was to investigate the etioprevalence of sub clinical mastitis (SCM) in Holstein x Haryana crossbred cattle. The relationship between somatic cell count (SCC) and ...

Copper deficiency is a commonly diagnosed problem in cattle around the globe. In Jimma, Ethiopia, 8 zebu (Bos indicus) and 8 zebu ×: Holstein Friesian cross (Bos taurus ×: Bos indicus) heifers were used in an 11-wk study to investigate breed type differences and effects of Cu deficiency on concentrations of trace elements in plasma and edible tissues as well as mRNA expression of Cu-related gen...

Fatty acid profiles in relation to meat quality traits and sensory palatability of grain-fed and grass-fed beef from Hanwoo, American, and Australian crossbred cattle were examined in this study. There were significant (p<0.001) differences in fat content and fatty acid compositions between grain-fed and grass-fed beef. Grain-fed Hanwoo had significantly (p<0.001) lower saturated fatty acid (SF...

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 survey was conducted to determine the prevalence of gastrointestinal parasitism in crossbred and local cattle, Sylhet division, Bangladesh. Fecal samples were collected randomly from 288 local and 144 crossbred cattle of four representative areas in three following seasons. The effects of season and age were tested in both local and crossbred cattle. Frequency of trematodes and nematodes infe...

The objective of this study was to determine the accuracy of prediction of body weight from body measurements in beef cattle. Wither height, chest girth, body length, chest depth, hip width and hip height measurements were obtained from Holstein, Brown Swiss and crossbred (n=140). Determination coefficients (R2) of regression equation that included all body measurements were higher in Brown Swi...

The world is going through the debate on hazardous effects of consumption of A1 milk on human health by producing of hazardous chemical compound like beta casomorphin-7 and how this is not the case with A2. The aim of the present study was to genotype the existing population of crossbred Holstein-Friesian (HF) cattle for polymorphism in â-Casein gene (CSN2) using PCR-RFLP technique. Total of 47...

This research aimed to determine the effect of dietary treatments and age on fattening process in cattle. Thirty-six Ongole crossbred cattles were allotted into two different three groups, with six replications for 24 weeks period, 4 preliminary followed by 20 data collection at Beef Cattle Research Station (BCRS). The experimental design was completely randomized a 2 x 3 factorial. cattle plac...

The major problems for the dairy practices in the tropical country are low milk yield and short lactation period of either pure exotic or crossbred dairy cattle. Many factors affect milk production in dairy cattle in tropical areas including high environmental temperature and humidity, lower genetic potential for milk production in indigenous cattle and inadequate supply of food during the dry ...
