Bovine tuberculosis is a major economic problem and a potential public health risk. Improved diagnostics like the gamma interferon (IFN-gamma) test with ESAT6 and/or CFP10 could contribute to the control program. We assessed IFN-gamma responses in zebu (Ethiopian Arsi breed) and Holstein cattle kept indoors or in a pasture to tuberculin purified protein derivative (PPD) and an ESAT6-CFP10 prote...
Six Holstein (light-muscled type) and six Belgian Blue bulls (double-muscled type) were fed a finishing diet. Average daily gain was 1.36 kg for the Holstein bulls vs 1.24 kg for the Belgian Blue bulls (P less than .05). Holstein bulls consumed more feed (2.3 vs 1.8 kg/100 kg body weight, P less than .001) than the Belgian Blue bulls. The dressing percentage (55.4 vs 65.8%, P less than .001) an...
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...
Approximately 20% of the beef tonnage produced in the United States is derived from Holsteins, through harvested dairy beef or cull dairy cows (Randy Blach, Cattle-Fax, personal communication). This represents a significant contribution to the U.S. beef supply. More and more large commercial feed yards have seen the opportunity available with feeding Holstein steers. Inherent variation between ...
درا ین مطالعه کلیه افرادی که تحت عمل tha در بیمارستان اختر از تاریخ 65-77 قرار گرفته اند از لحاظ عوارض و علل ونوع عمل تحت بررسی قرار گرفته اند. در مطالعه قوق مشخص گردید که شایع ترین شکایت بیماران در دو عیودیت حرکت بوده و شایع ترین علت ایجاد کننده secindary از نوع djd بوده است. و شایع ترین بیماران همراه fracture بوده است. و شایع ترین عوارض آن شامل dislocation بوده است.
Defi ciencies of Factor XI (FXID) and Uridine Monophosphate Synthase (DUMPS) are autosomal recessive inherited diseases in Holstein cattle breed. The aim of this study was to investigate whether FXI defi ciency and DUMPS alleles exist in Holstein cattle reared in Antalya region Turkey or not. 504 Holstein cows were used for this study. PCR (Polymerase Chain Reaction) was used for determination ...
*Corresponding Author Rajesh. K. Patel [email protected] The present study investigated the occurrence of an autosomal recessive genetic disease, Bovine Citrullinaemia caused by mutation in Argininosuccinate Synthase (ASS) gene, in Indian Holstein cattle. The Polymerase chain reactionRestriction fragment length polymorphism (PCR-RFLP) analysis was performed on a group of 120 Holstein bulls to...
Recent reports identified DGAT1 (EC 2.3.1.20) harboring a lysine to alanine substitution (K232A) as a candidate gene with a strong effect on milk production traits. Our objective was to estimate the frequency of the DGAT1 K232A polymorphism in the main Zebu and Taurine breeds in Brazil as well as in Zebu x Taurine crossbreds as a potential QTL for marker-assisted selection. Samples of 331 anima...
Induction of twinning by ipsilateral nonsurgical transfer of two frozen-thawed Japanese Black bovine embryos to each of 20 Holstein and 26 Japanese Black cows, that had been kept under a stable in private farm conditions, was examined. The cows were monitored every 20 days from Day 2.5 to Day 65 of gestation for pregnancy and fetus survival (estrus is Day 0). Seventy-five per cent ( 1.5 of 20),...
