S OF PAPERS 229 72 Effects of feeding various digestible lysine intake levels by Cobb 500 broiler breeder hens on reproductive performance. L. Mejia*SC, C. D. McDaniel, and A. Corzo, Mississippi State University, Mississippi State. A study was conducted to examine the reproductive parameters of Cobb 500 broiler breeder hens fed different daily consumption levels of dig lysine (mg/hen/day) on th...

Metabolic, immune, and physical status of chicks can impact the incidence of morbidity and mortality of broilers during the first week of production. Assessments of chick quality are made primarily by subjective observations with few quantitative measurements. Given a better understanding of how broiler breeder hen age and nutrient intake may influence progeny physiology, certain actions can be...

Two trials were conducted each using 240 Chinese Ringneck pheasant breeder hens (Phasianus colchicus torquatus) to determine the economics of feeding various levels of Brewers Dried Grains (BDG) on egg production, fertility, hatchability, and feed consumption. Four treatment diets containing 0, 15, 30, and 45% BDG were fed to 3 replicate pens each, beginning 1 week prior to the onset of lay. Eg...

An experiment was carried out to evaluate the effect of five commonly used antistress agents on haemato-biochemical profiles of broiler and broiler breeder hen. In case of broiler, significant differences were observed between treatment groups for haemoglobin concentration, total RBC and total WBC count, total blood glucose, total serum protein, total serum albumin, total alkaline phosphatase a...

Campylobacter and Salmonella are known to cause acute bacterial gastroenteritis in humans. Raw poultry products have been implicated as a significant source of these infections. Five trials were conducted to determine whether Campylobacter and Salmonella spp. exist naturally in the mature and immature ovarian follicles of late-life broiler breeder hens. Broiler breeder hens ranging from 60 to 6...

OBJECTIVES: The effect of photoperiod or melatonin treatments on ovarian adenocarcinoma in turkey breeder hens (Meleagris gallopavo) was investigated to evaluate the usefulness of this animal as a model for studying ovarian cancer. METHODS: In Experiment 1, photoperiod effects were tested by exposing turkeys with ovarian tumors to 8 wks of short days (8:16LD) followed by a 12 wk period of long ...

Published data on 4-week-long administration of exogenous thyroxine in broiler breeder hens to decline the cold-induced ascites in their progeny suggest that the long-term maternal hyperthyroidism would affect egg quality characteristics traits in Cobb 500 broiler breeder hens. Seventy 47-w-old broiler breeder Cobb 500 hens (5 replicates and 7 hens each) were assigned in separate cages and allo...
