Effect of Wet Feeding on Feed Conversion Efficiency in Laying Hens during Summer Season
The aim of this study was to investigate the effect of wet feeding on feed conversion efficiency in laying hens during summer season. The study was carried out on 192 pullets of eight weeks age (distributed to four groups). The feed offered to chicks consisted of starter diet up to 8 weeks of age and grower diet up to 20 weeks of age. From 20 weeks onwards, birds were provided with layer diet u...
متن کاملAdding Dried Distillers Grains to Swine Diets Affects Feed Preference
Three studies were conducted to evaluate the effects of dried distillers grains with solubles (DDGS) on feed intake in growing pigs. In all experiments, pigs were housed in 10.5 × 10.3 ft pens with four 1-hole feeders in each pen to allow pigs to choose from four dietary treatments. In Experiment 1, we evaluated the influence of DDGS drying method on palatability of DDGS. Diets were a control c...
متن کاملThermoregulation in pronghorn antelope (Antilocapra americana Ord) in the summer.
We have used thermistor/data logger assemblies to measure temperatures in the brain, carotid artery, jugular vein and abdominal cavity, and subcutaneously, in five pronghorn antelope over a summer in Wyoming. Globe and air temperature varied by up to approximately 50 degrees C daily during the summer and maximum solar radiation was approximately 900 W m(-2). Brain temperature (38.9+/-0.3 degree...
متن کاملA genetic analysis of feed conversion efficiency and associated traits in swine.
Performance records were analyzed for 1,869 purebred Duroc and Yorkshire gilts tested in littermate groups of two to four pigs in 703 pens. Traits studied were average daily gain during a standard test period from 56 d of age to 90.7 kg (ADG), average daily feed consumption during the test period (ADF), average backfat thickness (ABF) measured from polaroid photos of ultrasonic scans at 90.7 kg...
متن کاملEffect of dimetridazole on rate of gain and feed efficiency in swine.
D IMETRIDAZOLE (1,2-dimethyl-5-nitroimidazole) 2 is presently used in the United States and Canada for the prevention and treatment of histomoniasis in poultry. A stimulatory effect of dimetridazole on the growth of chickens and turkeys has been reported by Condren et al. (1963), Lucas (1963) and McGuire et al. (1964). In addition, dimetridazole has an inhibitory effect on the growth of certain...
