The objective of this study was to evaluate 3 milk replacer (MR) feeding programs on calf performance 4 mo age. Male Holstein calves (n = 48; 2–3 d old) were randomly assigned either a moderate rate MR (MOD; 0.66 kg/d for 39 d, then 0.33 d), an ad libitum (ADLIB; offered twice daily between 0630 and 0830 h 1430 1630 35 or step-up (STEPUP; increased from 0.32 0.62 in first 12 27 d). (25% CP, 18%...

background: tissue protective effect of compounds with antioxidant properties has been demonstrated. the alkaloids found in barberry root are considered as antioxidants. objective: according to barberry protective effects in different tissues, in this study, the protective effect of berberis integerrima bge. root )mebir) was evaluated against ccl4-induced testicular damages in wistar rats. mate...

AIM This study examined the effects of creep feed (CF) supplementation (with or without Alfalfa) on the pre-weaning growth performance of nursing goat kids. MATERIALS AND METHODS A total of forty eight (48), 7 days old, single born kids (live weight 4.4±0.09 kg) were divided into three treatment groups, each containing eight males and eight females. All three groups had access to their dams' ...

Angus bulls and heifers from lines divergently selected for serum IGF-I concentration were used to evaluate the effects of IGF-I selection line on growth performance and feed efficiency in 2 studies. In study 1, bulls (low line, n = 9; high line, n = 8; initial BW = 367.1 +/- 22.9 kg) and heifers (low line, n = 9; high line, n = 13; initial BW = 286.4 +/- 28.6 kg) were adapted to a roughage-bas...

Three commercial trials were conducted to evaluate the use of dexamethasone (Dex) and/ or isoflupredone (Predef) in improving preweaning growth performance of neonatal pigs. The objectives of the commercial trials were threefold: 1) to evaluate Predef in comparison with Dex; 2) to address the sexual dimorphic growth response observed in a previous commercial trial; and 3) to determine whether t...

The effects of dietary protein content on the rates of gain and protein deposition were studied in Iberian (IB) × Duroc (DU) 50:50 barrows at 2 stages of growth [10.6 ± 0.2 (n = 28) and 60.0 ± 0.4 (n = 24) kg initial BW]. Two feeding, digestibility, and N-balance trials were performed. At each stage of growth, they were allocated in individual pens and given restrictedly (at 0.9 × ad libitum in...

AIM The present investigation was to study genetic characteristics of Harnali sheep with respect to growth performance and to estimate genetic parameters. MATERIALS AND METHODS The 22 years (1992-2013) data of growth traits of a 1603 synthetic population of Harnali sheep maintained at Lala Lajpat Rai University of Veterinary and Animal Sciences, Hisar, was utilized for this study. A mixed met...

The objectives of the current experiment were to study the response of the growth performance of early finishing gilts to different net energy (NE) concentrations in diets, and to compare the NE values of diets between calculated NE values and measured NE values using French and Dutch CVB (Centraal Veevoederbureau; Central Bureau for Livestock Feeding) NE systems. In a metabolism trail, the NE ...
