Influence of constant enthalpy on broiler growth rate

Kennedy, Brian James January 1971 (has links)
An experiment was designed to test the hypothesis that enthalpy could be used as an indicator of the suitability of the environment for growing poultry. Growth-rates and body weights of the birds were used as a measure of their performance under different enthalpy conditions. The experiment tested three enthalpy treatments, ranging from 29.3 to 33.3 BTU/lb of air, each treatment being replicated three times. Male University of British Columbia New Hampshire chickens from nine hatches (120 birds per hatch) were used. They were grown from hatch to seven weeks of age in three groups. Two of the groups were raised from hatch to three weeks of age in controlled environment brooders. The third group was raised in a non-controlled environment in a floor pen, and used as a check or control group. The results of the analyses indicated that further study would be necessary before enthalpies in the range studied could be used to predict environmental conditions for poultry. / Applied Science, Faculty of / Chemical and Biological Engineering, Department of / Graduate

Natural development and dietary regulation of body and intestinal growth in broiler chickens

Iji, Paul Ade. January 1998 (has links) (PDF)
Corrigenda inserted behind title page. Bibliography: leaves 275-306. The pattern of body growth and intestinal development of an Australian strain of broiler chicken, the Steggles x Ross (F1) in response to different diets was studied. Five experiments were designed to examine the pattern of growth and mechanisms involved. In four other experiments, the mechanisms underlying the gross response of the broiler chicks to dietary ingredients, anti-nutritive factors and growth enhancers were examined. Results indicated that a rapid development of the small intestine preceded significant overall body growth. Body growth would, however, depend more on the various physiological events such as those related to mucosal growth and renewal, digestive enzyme function, and nutrient transport. Some of the differences observed in productivity of broiler chickens on different diets were traced to events at the intestinal level.

Genetic and nutritional factors affecting growth, nutrient utilization and body composition of broiler chickens

MacLean, Janice L. (Janice Leigh) January 1990 (has links)
Two growth trials were designed to measure the effects of: (1) dietary Virginiamycin (0 or 16.5 mg/kg) and added fat (0 or 4%), and (2) Virginiamycin (0 or 16.5 mg/kg) and dietary lysine levels (low, NRC, high) individually, and in combination on broiler performance. A third trial investigated the relationship of plasma glucose, triglyceride and phospholipid concentrations with degree of fatness/leanness in genetically lean and fat broiler chickens. A combination of supplemental fat and Virginiamycin increased protein and decreased fat content of the dressed carcass. Virginiamycin supplementation overcame the growth depression of a low lysine diet by increasing feed intake. In the low lysine diet, Virginiamycin supplementation reduced abdominal fat deposition in females and increased carcass yield in males. Carcass protein content was increased by feeding the NRC-recommended level of lysine or by Virginiamycin supplementation. (Abstract shortened by UMI.)
