Effects of implant programs on performance, carcass characteristics, and lipogenic gene expression in Holstein steers

  • 2008
  • Issue: 3
  • Volume: 38
R.C. Cheatham, G.C. Duff, C.R. Bailey, S.R. Sanders, R.J. Collier, J.A. Marchello and L.H. Baumgard Page: 238 - 246

Nineteen Holstein steers were randomly assigned to one of four treatments; no implant (CON); 36 mg zeranol (Ralgro) on d 0 and 20 mg estradiol benzoate plus 200 mg progesterone (Synovex S) on d 84 and 169 (RSS); Ralgro on…

Across flock genetic parameter estimation for yearling body weight and fleece traits in the South African Dohne Merino populatio

  • 2008
  • Issue: 1
  • Volume: 38
J.B. van Wyk, J.W. Swanepoel, S.W.P. Cloete, J.J. Olivier and G.J. Delport Page: 31 - 37

Accurate genetic parameter estimates are needed upon which to perform multiple-trait across flock breed analyses. Genetic parameters for yearling body weight (BW), clean fleece weight (CFW) and mean fibre diameter (MFD) were estimated using records of 107 389 individuals (the…

Leptin gene polymorphism in Indian Sahiwal cattle by single strand conformation polymorphism (SSCP) (Short communication)

  • 2008
  • Issue: 2
  • Volume: 38
P.P. Dubey, Ashwani Sharma, D.S. Gour, Prashant, Anubhav Jain, C.S. Mukhopadhyay, Avtar Singh, B.K. Joshi and Dinesh Kumar Page: 131 - 135

Leptin, a 16-Kilo dalton protein produced by the obesity (ob) gene, plays an important role in the regulation of feed intake, energy metabolism, growth and reproduction in cattle. The genetic variation of the leptin gene in Sahiwal cattle (Bos indicus)…
