Cottonseed Oil in Diets for Broilers in the Pre-Starter and Starter Phases
The objective of this study was to evaluate the effect of different levels of crude cottonseed oil in isoenergetic diets, with or without supplementation of ferrous sulfate, on performance variables, relative weight of organs, and blood parameters of broilers, and on the economic viability of diets in the periods from 1 to 7 and 1 to 21 days of age. A total of 600 male birds of the Ross line we...
متن کاملInteraction Between Crude Protein Level and Rumen Protected Amino Acids in Starter Diet on Performance of Dairy Calves
BACKGROUND: A limited number of studies have investigated the inclusion of amino acids in calf starter. OBJECTIVES: This study was aimed to evaluate different levels of crude protein in starter and supplement- ing some protected amino acids on efficiency, health status and blood metabolites of dairy calves and to com- pare it with unprotected amino acids. <st...
متن کاملThe Effects of Probiotic and Thyme Powder on Growth Performance, Carcass Traits and Blood Biochemical Parameters of Broilers with Normal and Crude Protein Reduced Diets
Extentet Abstract Introduction and Objective: Substances of microbial origin and medicinal plants, by improving the level of health and condition of the gastrointestinal tract, provide the basis for the optimal use of nutrients in diets, and by reducing the use of nutrients, while saving production, also prevent environmental pollution. Dietary protein sources are among the most expensive nutr...
متن کاملThe effect of the protein level in a pre-starter diet on the post-hatch performance and activation of ribosomal protein S6 kinase in muscle of neonatal broilers.
The cytoplasmic serine/threonine ribosomal protein S6 kinase (S6K1) plays a critical role in controlling protein translation. There is evidence that amino acids regulate S6K1 and protein synthesis in avian species, but the effect of dietary protein level on the activation of S6K1 in neonatal chicks is unknown. Therefore, the aim of the present experiment was to investigate the effect of differe...
متن کاملThe Effect of Crude Protein Level in Diets on Laying Performance, Nutrient Digestibility of Yellow Quails
Four diets with different crude protein levels 17.75%, 19.95%, 21.85%, 24.08% were used to feed 192 seven-week-old yellow quails in this experiment. During 50-day-old to 95-day-old, laying rate, feed intake and egg weight were recorded to analysis the effect of different levels of dietary protein on the performance of yellow quails. All fences were collected and analysis the effect of different...
