The effects of in ovo feeding arginine, beta-hydroxy-beta-methyl-butyrate, and protein on jejunal digestive and absorptive activity in embryonic and neonatal turkey poults.
In ovo feeding, injecting nutrients into the amnion of the avian embryo, may enhance jejunal nutrient uptake, activity of the intestinal enzymes, and posthatch growth. This hypothesis was tested in the following in ovo feeding (IOF) experiments. In experiment 1, 400 eggs were evenly distributed among 4 nutritional treatments at 23 d of embryonic development (23E) and administered 1 of 4 treatme...
متن کاملEffect of In Ovo Feeding Egg White Protein, β-Hydroxy-β-Methylbutyrate, and Carbohydrates on Glycogen Status and Neonatal Growth of Turkeys
In ovo feeding (IOF), injecting dietary components into the amnion about 1 d prior to internal pipping, may enhance growth by altering glycogen status. This hypothesis was evaluated with 5 IOF solutions containing protein, β-hydroxy-β-methylbutyrate (HMB), and carbohydrate. Four IOF treatments were arranged as a factorial of 2 levels of egg white protein (EWP; 0 and 18%) and 2 levels of HMB (0 ...
متن کاملCompetitive Edge: Review of the Role of Glutamine, Arginine and β -Hydroxy- β -Methylbutyrate Supplements for Enhancing Athletic Performance in Addition to Benefiting the Body During Times of Stress, Illness and Wound Healing
Glutamine, arginine and beta-hydroxy beta-methylbutyrate (HMB) are dietary supplements that may enhance athletic performance. Many sports competitions are won by a fraction of a second, so it is not surprising that athletes want to try the latest nutritional supplements to give them that competitive edge. Glutamine, arginine and HMB are just a few of many supplements that can aid performance. G...
متن کاملIn ovo feeding improves energy status of late-term chicken embryos.
Maintenance of glucose homeostasis during late-term embryonic development is dependent upon the amount of glucose held in reserve primarily in the form of glycogen in the liver and upon the degree of glucose generated by gluconeogenesis from protein first mobilized from amnion albumen and then from muscle. Insufficient glycogen and albumen will force the embryo to mobilize more muscle protein t...
متن کاملEffects of 12 weeks of beta-hydroxy-beta-methylbutyrate free acid gel supplementation on muscle mass, strength, and power in resistance trained individuals
Background Previous research in trained individuals supplemented with beta-hydroxy-beta-methylbutyrate (HMB) has been constrained to short (<10 weeks), non-periodized studies, lacking dietary control, that were subject to poor outcome measures (e.g. skin caliper measurements). These conditions make it difficult to determine HMB’s effects in athletes. The primary purpose of this study was to inv...
