Dietary Riboflavin Needs for Body Maintenance and Body Protein and Fat Accretion in Pigs
نویسنده
چکیده
and Implications The dietary bioavailable riboflavin needs for body maintenance and body protein and fat accretion were estimated in pigs. The riboflavin required to support body protein accretion was higher than that for body maintenance or fat accretion. Specifically, the riboflavin required to support protein accretion was six times higher than the riboflavin required to support fat accretion. Based on these data, both biological and environmental factors that alter body protein accretion in pigs will substantially alter riboflavin needs. In addition, the dietary bioavailable riboflavin required by high-lean, high-health pigs is greater than the current NRC (4) estimate.

Fat requirement of Bester in winter feeding; effect of fat levels on growth indices and body chemical composition
This study aimed to determine the fat requirement and effect of dietary fat levels on growth and body composition indices of Bester (Huso huso ♀ × Acipenser ruthenus ♂) juveniles( 200.3 ± 2 g) in winter feeding. Fish were fed by 5 isonitrogenous diets (40% crude protein) with different fat levels including 10, 13, 16, 19 and 22%, 3 times daily according to the satiation for 50 days. The results...

Pigs of a high lean strain reared via an SEW scheme were self-fed a basal diet supplemented with 0, 15, or 30 mg niacin/kg diet from 10 to 27 kg body weight. The basal diet contained 18 mg of total niacin and 9.4 mg of bioavailable niacin per kg diet. Dietary niacin supplementation did not alter pig growth, efficiency of feed utilization, or body nutrient (protein, fat) accretion. Based on thes...
متن کاملEstablishment of the Minimum Biological Capacity for Nitrogen Excretion in Pigs
To determine the minimum biological capacity for nitrogen (N) excretion for pigs, dietary regimens were created and fed that were designed to eliminate fecal excretion of undigested feed N, minimize endogenous N secretions and minimize intakes of nitrogenous compounds (amino acids) above those of the pigs biological needs. Excretion of undigested fecal N was eliminated by feeding ingredients co...

This study aimed to determine the fat requirement and effect of dietary fat levels on growth and body composition indices of hybrid Asp (Leuciscus aspius ♀) × Caspian Kutum (Rutilus frisii ♂). For this purpose, 252 fish with an average weight of 29.3 ± 5.8 g were introduced in a completely randomized design with six treatments each with triplicate groups. After two weeks of adaptation, fish wer...
متن کاملDietary L-carnitine improves nitrogen utilization in growing pigs fed low energy, fat-containing diets.
Growing pigs (n = 25; 17.8 +/- 0.1 kg) were used to study the effects of L-carnitine and protein intake on nitrogen (N) balance and body composition. Fat-supplemented (40 g soy oil/kg diet), corn-soybean meal basal diets containing low or high protein (136 or 180 g/diet) were formulated so that protein accretion would be limited by metabolizable energy (ME). Each basal diet was supplemented wit...
