Abstract The growth performance, carcass characteristics, and methane emissions from feedlot beef cattle fed a high-lipid finishing diet (7.3% of ether extract) were evaluated. Fifty long-yearling young bulls divided into two groups following their breed composition: Nellore (n = 25) Angus × crossbred 25), randomly assigned 4 pens (12 or 13 animals/pen) completely randomized design. Animals sou...

The aim of the present study was to evaluate the impact of zilpaterol hydrochloride (ZH; 0 or 10 mg/lamb daily) and soybean oil (SBO; 0 or 6%) supplementation on feedlot performance, carcass traits, and wholesale cut yield of 32 Dorper × Pelibuey ewe lambs (30.55 ± 2. 57 kg of initial BW). Lambs were blocked by BW and randomly assigned to treatments under a randomized complete block design with...

This experiment was conducted to determine the effects of Myrtle Essential Oil (MEO) on growth performance, carcass characteristics, antibody titer and blood parameters of broiler chickens. A total of 200 Ross 308 broiler chickens were allocated to five dietary treatments with four replicates of 10 birds each. Dietary treatments were prepared by formulating a corn-soybean meal-based diet free o...

Nguyen, T.V. and Bunchasak, C. Effects of dietary protein and energy on growth performance and carcass characteristics of Betong chicken at early growth stage Songklanakarin J. Sci. Technol., 2005, 27(6) : 1171-1178 Four hundred and sixteen one-day-old Betong chicks were used to determine the effect of dietary protein and energy levels on growth performance and carcass characteristics. The chic...

In order to assess the effect of a probiotic and population density on the growth performance and the carcass characteristics in broiler chickens, an experiment was conducted involving 208 1-day-old Peterson brand chicks. They were fed a corn and soy paste diet with 23 and 20 percent crude protein at the first and last stage respectively and 3.2 Mcal ME/kg. A completely randomized design with a...
