Effects of in ovo injection of carbohydrate solution on small intestine development in domestic pigeons (Columba livia).
The objective of this study was to test the hypothesis that in ovo injection of carbohydrates into pigeon (Columba livia) amnion may improve the small intestine development. At d 14.5 of incubation, 80 fertile eggs were injected with 200 μL of carbohydrate solution, and 80 control eggs were not injected. The carbohydrate solution (wt/vol) contained 2.5% maltose + 2.5% sucrose, all dissolved in ...
متن کاملRelationship Between Egg Weight and Hatch Weight in Pigeons (Columba livia)
This study was undertaken to assess the relationship between egg weight and hatch weight in pigeons and also derive prediction equation based on the relationship. It was conduced in nine randomly selected households in Misau town of Bauchi State, Nigeria, between April and November 2009. The mean egg weight and squab hatch weight were 14.46±0.11 g and 12.55±0.08 g, respectively. No significant ...

two experiments were conducted to evaluate the effects of thyroxin in ovo injection and post hatch arginine feed supplementation on performance and cold tolerance acquisition in broilers. in experiment 1, a total of 2400 hatchings eggs were randomly assigned to four treatments: positive controls (intact or pricked with a needle), negative control (intact egg), injected with distilled water and ...
متن کاملEffects of in ovo feeding of carbohydrates on hatchability, body weight, and energy status in domestic pigeons (Columba livia).
The effects of in ovo feeding of carbohydrates on hatchability, BW, yolk sac weights (YSW), pectoral muscle weights (PMW), liver and pectoral muscle glycogen concentration, serum glucose level, and hepatic glucose-6-phosphatase activity of domestic pigeons, hatched from eggs laid by a 40-wk-old breeder flock, were investigated. At 14.5 of incubation, fertile eggs were injected with 200 μL of 1....
