to evaluate the effects of wheat processing and dietary lipid sources on feedlot performance, carcass characteristics and fatty acids profile in meat of fattening calves, a number of 28 holstein male calves averaging in weight of 296±56kg were randomly allotted in four treatments (7 steers each). the study was conducted in a 2 × 2 factorial arrangement (two methods of wheat processing: steam fl...

Two studies were conducted to investigate the effects of anti-diarrhoeal herbs on growth performance, nutrient digestibility, and meat quality in pigs. In Exp 1, 150 weanling-growing piglets (average BW = 7.5±0.24 kg, average age = 27±1 d) were allotted into one of the five dietary treatments, including: i) CON, basal diet, ii) DP, basal diet+1 g/kg date pits, iii) JH, basal diet+0.5 g/kg Japan...

Purebred and two-breed cross (F1) boars were mated to F1 females to produce all possible three- and four-breed cross pigs involving the Duroc, Yorkshire, Landrace and Spotted breeds. Individual postweaning average daily gain (ADG), age at 100 kg (AGE) and probed backfat thickness at 100 kg (BF) data were collected on 3,456 pigs. A total of 213 pens with an average of 15.58 pigs per pen was eval...

An 8-wk growth trial was conducted to assess the effects of ovine growth hormone (oGH; 7 mg/d, sc) on growth performance and carcass composition of normal, growing wether lambs. Diethylstilbestrol (DES; .1 mg/d, sc) and control lambs were included for comparisons. Plasma oGH levels at 8 wk were 1.9, 5.5 (P less than .05) and 138.1 ng/ml (P less than .001) for controls, DES and oGH lambs, respec...

The effects of herd of origin by year on the average daily gain (ADG), average daily feed intake (DFI), shoulder height (SDH) and scrotal circumference (SCR) of beef bulls at centralized test centres in South Africa were investigated using data of Bonsmara cattle. Data consisted of post-weaning traits of beef bulls tested between 1990 and 2003, with available weaning weight (WWT) and weaning ma...

AIM The study was conducted at a smallholder goat farm located in Labu, Negeri Sembilan, Malaysia. The objective of this study was to evaluate the effect of proper feeding program on growth performances of replacement breeder goats. MATERIALS AND METHODS A total of 30 healthy female boer cross goats at the age of 4 months old with average initial live body weight (BW) of 20.05±0.5 kg were use...

Livestock body weight (BW) and average daily gain (ADG) are primary indicators of beef cattle productivity. The conventional method weighing involves moving the to a location, which is labor-intensive, stressful for animals has negative impact on their growth. An alternative approach use special platforms attached drinkers weigh animals. This enables monitoring BW ADG without incurring addition...

Aim of study: To investigate the effect feeding foliage leguminous trees on growth rate, semen characteristics, and sexual behavior bucks.
 Area Northeastern Mexico (23°44' N, 99°8' W).
 Material methods: Twenty-two young goat bucks were randomly allocated to one four treatment groups: 33% alfalfa hay (dry matter basis), 33%; Acacia farnesiana; Leucaena leucocephala; or Prosopis laevi...

The objective was to compare and analyze the relationship between growth, purine content, uric acid, superoxide dismutase (SOD) in purebred crossbred Thai native chickens. A total of 300 chickens were divided into 3 groups. Group 1 (100%TN), 2 50% (50%TN), 25% (25%TN). Data included body weight (BW), average daily gain (ADG), breast circumference (BrC). At 6, 8, 10 weeks age, from each group ra...

An experiment was conducted to investigate the effects of post-weaning dietary protein supply and weaning age on the performance of pigs in the absence of in-feed antimicrobial growth promoters (AGP) when artificially challenged with enterotoxigenic Escherichia coli (ETEC), a pathogen associated with post-weaning colibacillosis (PWC). The experiment consisted of a complete 2 × 2 × 2 factorial c...
