We examined the effects of vitamin and mineral supplementation of the finishing diet on growth and accelerated chilling of carcasses on carcass and muscle traits of halothane gene carrier and noncarrier pigs. Barrows and gilts that were either monomutants (MON, n = 49) or noncarriers (NON, n = 28) of the halothane gene were fed a standard finishing diet until they reached 86 kg. They then were ...

the present study was carried out to determine the effects of supplementing chromium-methionine(cr-met) on performance and carcass traits in mahabadi goat kids. thirty-two male kids (averageinitial bw of 22 ± 2 kg, 4-5mo) were used in a completely randomized design of four treatments vis.:1) control (with no cr suppl.), 2) 500ug cr suppl., 3) 1000ug cr suppl.and 4) 1500ug cr suppl.as cr-met/ani...

The essentiality of certain amino acids and certain fatty acids was established for growing rats at about the same time. W.C. Rose at the University of Illinois in the early 1930’s identified 10 essential dietary amino acids for rats. Soon thereafter, these same essential dietary amino acids were confirmed experimentally in growing nonruminant livestock. The fatty acids, linoleic acid (C18:2) a...

this experiment was conducted to evaluate the effects of supplemental l-arginine (arg) in reduced-protein diets on cardiopulmonary performance and intestinal morphology in the broilers reared at high altitude. a total of 156 day-old male broilers were randomly assigned to 3 treatments and 4 replicates of 13 chicks and reared up to 42 days of age. treatment groups were designed as a normal-prote...

Ten crossbred barrows (48.3 +/- 2.3 kg of initial BW) fitted with steered ileo-cecal valve cannulas were used to investigate the effects of supplemental microbial phytase on the apparent ileal digestibilities (AID) of AA, Ca, P, N, and DM, and the apparent total tract digestibilities of Ca, P, N, and DM. All diets were corn-soybean meal-based, and contained 0.44% Ca and 0.40% total P. Diets 1, ...

Abstract Katuk leaves ( Sauropus androgynus (L.) Merr.; KL) are widely consumed by breast-feeding Indonesian mothers as it has been reported to increase breast milk production. It is hypothesized that supplementing KL in diets might crude protein (CP) concentration and fibre digestibility the diet. The had high CP non-fibre carbohydrate concentrations (333 332 g/kg dry matter; DM, respectively)...

The addition of supplemental fatty acid (FA) sources to diets is a common practice in dairy nutrition to increase dietary energy density and to support milk production. Recently, the effects of individual FA on digestibility, metabolism, and production responses of dairy cows has received renewed attention. In fresh cows, the high metabolic demand of lactation and reduced DMI during the immedia...

I . Urinary excretion of total ether-soluble acids and of methylmalonic acid was studied in rats on vitamin BI2-deficient diets with and without a vitamin Blz supplement. 2. It was shown that urinary excretion of total ether-soluble acids and methylmalonic acid was increased in vitamin R1,-deficient rats and that this increase was somewhat variable between individual animals, males and females,...
