Effects of Supplementing Broiler Diets Low in Crude Protein with Essential and Nonessential Amino Acids
A study was conducted to evaluate the effects of adding all essential amino acids (EAA) equal to that of higher CP diets or a mixture of nonessential amino acids (NEAA) to low CP diets on the live performance of broilers during the period of 0 to 21 d. A series of experimental diets comprised primarily of corn and soybean meal were formulated to contain 3,200 ME kcal/kg. Five primary diets were...
متن کاملThe Effect of Broiler Breeder Strain and Parent Flock Age on Hatchability and Fertile Hatchability
The effect of genetic strain (Ross 308; Cobb 500) and parent flock age (Ross at 32 and 36 weeks; Cobb at 26 and 44 weeks of age) on hatchability, fertile hatchability, Egg Weight Loss (EWL) and egg break out analysis were examined. At each flock age, 300 eggs from each treatment group were incubated. Thirty eggs from each treatment group were labeled individually for the measurements of Egg Wei...
متن کاملMetabolic Effects of Polyunsaturated Fatty Acids in Chickens: A Review
Chicken has been used as a suitable model for lipid metabolism studies, because dietary modifications especially dietary fat type can change chicken body composition. Fats act as a condense source of energy and certain fatty acids such as polyunsaturated fatty acids (PUFAs) are required for both animal and human health. The n-3 PUFAs, especially, eicosapentaenoic acid (EPA) and docosahexaenoic ...
متن کاملEffects of dietary polyunsaturated fatty acids on ovarian function and prostaglandin secretion in lactating dairy cows
As lactating cows in severe negative energy balance have poor reproductive performance, the effect of dietary fat supplementation (fish oil, soybean oil) on PGFM secretion, ovarian function and blood metabolites is investigated. In this experiment, the effects of dietary polyunsaturated fatty acids on plasma metabolites, ovarian function and prostaglandin secretion of 20 primiparous Holstein co...
متن کاملO-11: Diverse Effects of Polyunsaturated Fatty Acids on Oocyte Maturation and Development In vitro
Background: Polyunsaturated fatty acids (PUFAs) have been shown to influence fertility and endocrinology of reproduction and metabolic activity in many species. In dairy cows, we and others have shown changes in steroid and metabolic hormones and prostaglandins leading to alteration of ovarian activity and uterine function. These can influence fertility by changes in folliculogenesis cyclicity ...
