Lysine levels in diets for broilers from 8 to 21 days of age

Revista Brasileira de Zootecnia, 2013
This study was conducted to evaluate the effects of digestible lysine levels in diets with and without supplementation of industrial amino acids on performance and fat deposition in the carcass of broilers in the starter phase.

Effect of barley or rape seed cake as supplement to silage for high-yielding organic dairy cows [PDF]

, 2002
An experiment was carried out to investigate the effects of barley or rape seed cake as supplement to silage given ad libitum on milk production and health of dairy cows. A total of 103 cows were divided into two groups on two farms.

Accretion Rates and Efficiency of Amino Acid Utilization during the Twenty-nine Days Post-Hatch Period in Male Ducks

The Journal of Poultry Science, 2012
The amino acid contents of whole body were determined in male ducks at 5 age intervals from d 1 to 29 post hatch. Whole body homogenates were analyzed of dry matter, nitrogen, and amino acids and used to determine amino acid accretion rates and ...

Initial assessment of protein and amino acid digestive dynamics in protein-rich feedstuffs for broiler chickens.

PLoS ONE, 2020
A study evaluating apparent digestibilities of protein and amino acids and their corresponding digestion rates in four small intestinal sites in broiler chickens was completed to further investigate dietary optimisation via synchronised nutrient ...

Protease Supplementation under Amino Acid Reduction in Diets Formulated with Different Nutritional Requirements for Broilers

Brazilian Journal of Poultry Science, 2019
This study aimed to evaluate the effect of different reductions in digestible amino acids content (lysine, methionine, and threonine), according to two nutritional requirements in corn, soybean meal, and meat and bone meal based diets, with protease ...

The effects of medium-oil dried distillers grains with solubles on growth performance and carcass traits in finishing pigs [PDF]

, 2012
An experiment was conducted to determine the effects of increasing medium-oil dried distillers grains with solubles (DDGS; 7.4% fat, 28.1% CP, 10.8% ADF, and 25.6% NDF) on growth performance and carcass traits in finishing pigs.

Effect of amino acid deficiency on precaecal amino acid digestibility in broiler chickens

Journal of Animal Physiology and Animal Nutrition, 2019
AbstractIn this study, we determined whether deficient dietary amino acid (AA) concentrations influence the precaecal (pc) AA digestibility when determined using the regression approach. We mixed two basal diets. Basal diet 1 was deficient in essential AAs, whereas adequate AA concentrations were ensured in basal diet 2 by adding free AAs.

THE METABOLISM OF AMINO ACIDS AND CASEIN DIGEST IN PHLORHIZINIZED DOGS [PDF]

Journal of Experimental Medicine, 1947
When solutions of sugar-forming amino acids are given parenterally or orally to phlorhizinized dogs, extra sugar and nitrogen are excreted in the urine. The route of administration does not influence the way in which the amino acids are metabolized.

Plasmatic Urea Nitrogen in Growing Rabbits with Different Combinations of Dietary Levels of Lysine, Sulphur Amino Acids and Threonine

Animals, 2020
A total of 27 experimental diets were formulated starting from the same basal mixture, with a moderate content of crude protein and digestible energy (155 g and 9.86 MJ/kg of digestible matter (DM), respectively, both estimated).
