Genotype by feeding regimen interactions in growth selected chickens
… in lines of chickens maintained under different feeding regimens. Populations included a commercial broiler breeder parent line segregating at a sex-linked feathering locus (K, k⁺) and 4 experimental lines of which 2 had undergone 32 generations of divergent selection for 56-day body weight and 2 …

Effect of Feeding Regimen and Age on Lipid Metabolism in Broiler Breeder Hens and Progeny
… conducted to determine the effects of age and feeding programs on lipid metabolism in breeder hens and progeny. In the first trial, the rate of yolk absorption and fatty acid profiles in the yolk were compared among 28, 35, and 49wk old hens. The results revealed that the rate of yolk …

Genetic and Genetic-Feeding Regimen Interaction Effects on Lactation, Growth and Carcass Traits in Dairy Cattle
Average daily gan (ADG), usually estimated from initial and final body weights, ignores information provided by intermediate body-weight measurements. Alternative methods to obtain a more precise estimate of ADG were developed and compared using simulation. Estimated generalized least-squares …

Rapid versus slow rate advancement of feeds for enterally fed extremely low birth weight infants < 1000g: randomised controlled trial
… wellbeing. However, the optimal enteral feeding regimen for preterm infants has not been established, and wide variations occur in practice. The debate on the most appropriate feeding strategy is nuanced by studies suggesting that early introduction of enteral feeds and the rapid …

Genotype by nutrition interactions for immunoresponsiveness and disease resistance in chickens
… stocks maintained under different nutritional regimens. Genetic stocks included (1) a commercial layer line, (2) commercial broiler lines, (3) a White Rock line selected for high juvenile body weight, (4) a White Leghorn line selected for low antibody response to sheep erythrocytes, (5) a fast …

Selected experiments on growth and food conversion efficiency of bluegill, Lepomis macrochirus
… to determine the effect of aquarium volume and feeding regimen on growth in length and weight and on food conversion efficiency by bluegill fed rations of mealworms. Two 30 day periods were utilized for each study. Part one, which examined the effect of aquarium volume on growth extended from …

Effects of diet on body weight, body composition, metabolic status, and physical activity of adult female dogs after spay surgery
… were not different. When comparing data by feeding regimen (restricted vs. ad libitum phase), several treatment*feeding regimen and treatment effects were observed. During the first 12 wk, HP-HF and HP-HF-O dogs had a greater reduction in serum cholesterol (p<0.001) and CALP concentrations …

Stress response and habituation as influenced by nutritional and thermal factors in dwarf and normal chickens
… than ad libitum fed chicks. Neither genotype nor feeding regimen had an effect on antibody response to SRBC. Frustration induced by thwarting of feeding resulted in a dramatic elevation in HIL ratios and conspicuous behavioral responses, suggesting responses to fasting may be physiologically and …

An Ecological Approach to Feed Management in Fish Rearing Ponds
… using three different rates of feed addition (no feeding, 1%, or 3% body-weight/day, BW/d). Ponds in the 3% BW/d treatment had low dissolved oxygen (DO) concentrations and their surface became covered by filamentous green algae. Further, the feed did not enhance or support production of live prey …
