Two hundred and ninety-four pigs were used to assess the effect of two ingredients (Lupinus albus (albus lupins) or a combination of calcium chloride and sodium tri-polyphosphate (mineral salts)) on growth performance, body composition and objective meat quality of pigs immunized against gonadotrophin releasing factor (immunocastrates) and entire male pigs in the late finishing phase. Pigs fed ...

A detailed model was developed for the emulsion copolymerization of styrene and MMA to predict the evolution of the particle size distribution (PSD) and molecular weight distribution (MWD) over the entire range of monomer conversion. A system exhibiting zero-one kinetics was employed. The model was used to optimise the emulsion copolymerization process in order to maximize particle size polydis...

In a 2×2 factorial experiment the hypotheses tested were that the metabolic acid load caused by benzoic acid (BA) added to the feed affects bone mineralization of weanling pigs, and that a wide dietary calcium (Ca) to phosphorus (P) ratio in phytase-supplemented feeds with a marginal P concentration has a positive effect on bone mineralization. The four experimental diets, which contained 0.4% ...

Effect of vitamin A deficiency was determined on the immune response of broilers. The experimental feed was prepared having vitamin A level at the rate of 500 IU/kg of feed. Vitamin A deficiency in feed significantly lowered (P<0.05) the gain in body weight with poor feed conversion ratio (FCR). In Newcastle disease virus (NDV) infected broilers kept on vitamin A deficiency showed greenish whit...

The purpose of this study was to determine the survival rate (SR), Average Daily Growth (ADG), and Feed Conversion Ratio (FCR) Nile tilapia (Oreochromis niloticus) with a dynamic system model. model is used optimal value three variables. results showed that rate, average daily growth, feed conversion ratio cultivation were 93% 3.2gr/day 0.73 (FCR). In research, production 14,199gr, amount 10.34...

ROWTH rate and efficiency of feed utilization are two of the most economically important characters in the production of meat animals. In these days of world shortage of both plant and animal protein, and with an energy crisis looming on the horizon, the necessity both to reduce maintenance costs by speeding up growth rate and to improve the efficiency of growth by improving the efficiency of c...

Commercial broiler males were used to evaluate body temperature response to heat stress and its relationship to gain, feed consumption, and feed conversion ratio. Individual gain, feed consumption, and feed conversion ratio were obtained from 28 to 49 d in a heat stress environment (32 C) and compared to a 21 C environment. Body temperatures were measured at 28, 35, and 42 d, then daily from 43...
