this experiment was conducted to investigate the effects of using protexin, propionic acid growth promoters, and a blend of them on broilers performance. in a completely randomized design, three hundreds and twenty unsexed 1-d-old chicks were divided into four groups. dietary treatments were consisted of 1) control diet without any supplement, 2) the control diet + 0.01 % protexin, 3) the contr...

Tilapia (Oreochromis niloticus) is one of the prospective freshwater fish producers to be developed in Indonesia. fishcommodities that has received great attention from fisheries because itis easy breed, grows fast, and tolerant unfavorable environments. One ofthe problems tilapia farmersis high feed cost. The factor affects growth nutritional content feed. To increase thegrowthoftilapia,qualit...

a random block experiment 4×4 with sixteen diets containing four level of protein (35, 40, 45 and 50%) at four carbohydrate to lipid level (1.7, 1.4, .1 and 0.8 ) were designed to research about the ability of utilization of different levels of protein and carbohydrate to lipid ratios diet for juvenile huso huso ( 5.4 ± 0.2, mean sd )in fourteen weeks. fish fed 2-3% of body weight at each day. ...

two experiments were conducted to determine threonine (thr) requirements of two commercial strains, ross 308 and cobb 500, based on standardized ileal digestibility from 15 to 28d of age. basal diet consisted of wheat, triticale, and corn gluten meal was formulated according to quick chick (2006) to be adequate in all nutrients except for thr. incremental levels of supplemental thr were added t...

This investigation aimed to assess genetics of body conformation and feed efficiency traits in a control line of Rhode Island Red (RIR) chicken taking single hatched out pedigreed 100 chicks at Central Avian Research Institute, Izatnagar, India. Data was analyzed by least squares analysis of variance. Least squares means of chick weight (CW), body weight (BW), shank length (SL), keel length (KL...

in order to survey the inclusion effects of different levels of barley and/or corn grain in diet on growth and performance of holstein calves 40 newborn calves were taken in 5 experimental groups with 4 female and 4 male calves in each group for a duration of105 days. the experimental group was comprised of: group 1; no barley (only consisting of corn grain) and other experimental groups 2, 3, ...

Aim The purpose of this study was to know the production performance and economic analysis in quail which use probiotic supplementation to alternate antibiotic growth promoter (AGP) to feed consumption, water consumption, egg production, egg mass, feed conversion, and feed efficiency. Materials and Methods About 240 quails (Coturnix coturnix japonica) at 14 weeks of age were completely random...
