The effects of egg storage duration (ESD) and brooding temperature (BT) on BW, intestine development and nutrient transporters of broiler chicks were investigated. A total of 396 chicks obtained from eggs stored at 18°C for 3 days (ESD3-18°C) or at 14°C for 14 days (ESD14-14°C) before incubation were exposed to three BTs. Temperatures were initially set at 32°C, 34°C and 30°C for control (BT-Co...
Antibody responses to a first, second, and third injection with SRBC, and growth were studied in lines of White Leghorn chickens selected for high (HA) or low (LA) 5-d antibody titers to an i.v. inoculation with 0.1 mL of a 0.25% suspension of SRBC. The experiment involved parallel studies on two groups of chicks hatched from the same matings of parental lines HA and LA at a 14-d interval. Chic...
The effects of odor exposure during the last 2 days of incubation and immediately after hatching on subsequent responses by chicks to that same scent were assessed. When tested with an orange-treated and an unscented container, chicks that had been previously exposed to orange odor more rapidly approached both containers than did control chicks and spent more time near them. In both conditions,...
Two experiments were conducted to evaluate the effects of fusaric acid (FA) in broiler chicks (Exp. 1) and turkey poults (Exp. 2). In each experiment, 100 day-old birds were allotted randomly to dietary treatments containing 0, 100, 200, 300, or 400 mg FA/kg of feed. Each dietary treatment was fed to 4 pen replicates of 5 birds each for 21 days. Fusaric acid had no effect (P > 0.05) on feed int...
Background & Aim: Dill “Anethum graveolens” is an annual medical plantin the celery family “Apiaceae”. It is the sole species of the genus “Anethum”.The health advantages of dill seed include its ability to increasedigestive health, as well as providingrelief from insomnia, hiccups, diarrhea, dysentery, menstrual disorders, respiratory disorders, and ...
Responses to stunting syndrome (SS) infective material obtained from affected broilers and administered per os were monitored for 3 wk in a fast-growing commercial broiler population, in slow-growing Leghorn chicks, and in turkey poults. At 2 and 3 wk, the size of the gastrointestinal tract (GIT) segments, the pH of the GIT contents, and the activities of digestive enzymes in the intestinal con...
The effects of taurine supplementation on growth performance, serum and liver concentrations of lipid, fatty acid composition and lipid peroxidation in the livers of broilers under chronic heat exposure conditions were investigated. The chicks with a similar body weight were equally assigned to one of three controlled-environment chambers. The brolier chicks, which were kept at 34°C were fed ei...
The effects of feeding meals, in amounts equivalent to ad lib, intake or to 75% and 50% restriction by intubation, were studied in chicks. Growth estimated by body-weight gain and shank length was improved by tube feeding in the 50%-restricted chicks. Tube feeding increased energy retention at all feeding levels and nitrogen retention in the restricted chicks only. Body fat was increased in the...
Sooty shearwater (Puffinus griseus) harvest intensity and selectivity on Poutama Island, New Zealand
Rakiura Maori annually harvest sooty shearwater (Puffinus griseus) chicks from islands in Foveaux Strait and adjacent to Stewart Island, New Zealand. Chick availability and the number of chicks harvested were estimated during the 1994 and 1995 seasons on Poutama (Evening Island). Burrow entrance densities estimated using circular plots were significantly higher in 1994 (0.45 ± 0.03 m) than in 1...
The present work was carried out to evaluate and compare the productive and physiological performance and carcass traits of two local strains of chicks. Also, to find out the relationship among the studied traits. A total number of 450 one – day old chicks from each of Silver Montazah (S.M) and Matruoh (MAT), strains (210 males and 240 females) were randomly divided into four experimental group...
