BACKGROUND Conventional vaccination programs using a single injection of a combined vaccine against porcine circovirus type 2 (PCV2) and Mycoplasma hyopneumoniae (MHYO) can promote a strong immune response that reduces feed intake for 24 to 48 h post injection. Often such vaccines are given around the time of weaning during a critical stress period in which feed intake is already compromised. S...

The United Kingdom Home Office Code of Practice for the housing and care of breeding animals requires that, 'the general well-being of all animals must be checked at least once daily'. However, excessive daily disturbance of rodent breeding colonies could be counter-productive to animal welfare if it increases pre-weaning mortality. An experiment involving 100 breeding cages of BALB/c mice comp...

One hundred fifty Simmental-Hereford cows and calves were used in a 3-yr study to evaluate three creep grazing treatments and an early weaning treatment on cow and calf performance during midsummer (July to September). Calves were approximately 150 d of age and averaged 178.6 kg when treatments were initiated. Tifleaf pearl millet (Pennisetum Americanum L. Leeke) was used as the forage for two ...

Aim of study: To describe and predict mathematically the growth parameters Iberian pigs.
 Area dehesa agroforestry system. Southwest Peninsula.
 Material methods: A quantitative systematic review was carried out to find all studies with valid data finishing in swine breed published up May 2020. For analysis data, a mathematical fitting model obtained function postulated relation betwe...

Main aim of this work was to findout the influence probiotic supplementation and suitable dietary protein level in creep feed for optimum growth performance Salt Range lambs. Lambs (n ₌ 16; Age 30±10 days) were chosen divided into four equal groups. Four treatments; diet-1 (CP 18% with no probiotic), diet-2 diet-3 20% noprobiotic) diet-4 probiotic) randomly allocated lambs under Completely Rand...

in order to investigate the effect of processing type (whole straw bale processing or opened straw bale processing with urea) on diet digestibility, economical and productive parameters in feedlot cattle, 18 holstein bull with average body weight 224.72 ± 20.45 kg were used in a completely randomized design with 3 treatments and 6 replicate. treatments 1, 2 and 3 contained 40% typical straw, 40...

Twelve Hereford bulls were used to sire calves in each of three locations in North Carolina over 6 yr. Three bulls were bred artificially to a random one-third of the cows at each location each year. Locations represented the Mountain, Piedmont and Coastal Plain regions of the Southeast. As yearlings, steer progeny were fed a concentrate diet in a feedlot or grazed on pasture and then slaughter...
