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...

the subgroup j of alv (alv-j) has emerged as an important pathogen of meat-type chickens since1989. this virus is responsible for economic losses due to both mortality and depressed performance inchickens. so, the objective of this study is the detection of alv-j in the albumen of commercial and nativefowl eggs using rt-pcr. three hundred and seventy egg albumens were randomly selected from dif...

Aim: To compare the amylase activity in the cervical mucus and serum during estrus in normal and repeat breeder cattle and find out importance in fertility. Materials and methods: Twenty cyclic crossbred cattle were divided into two groups: normal (n =10) and repeat breeder (n =10). Animals exhibiting spontaneous estrus, were artificially inseminated (AI) twice, as per AM-PM schedule along with...

Fast Breeder Test Reactor (FBTR) operating at IGCAR since 1985 is testimony of maturity India has attained in Fast Breeder Technology. The reactor has operated exceedingly well thus established the competence of Indian engineers in handling this difficult technology where large quantity of sodium is used for cooling of reactors. INDIA took quantum leap from 40 MWe FBTR to launch of 500 MWe Fast...

Contaminated poultry and poultry products are a major source of motile Salmonellae for human salmonellosis worldwide. Local circulation of any motile Salmonella serovar in poultry has a wider public health impact beyond its source of origin for being dispersed elsewhere through poultry trades or human travels. To investigate the status of motile Salmonella serovars in breeder farms in Banglades...

Trace minerals, such as Zn, Mn, and Cu, are components of eggs that are essential for broiler breeder performance as well as chicken embryo development [1, 2]. These trace minerals are constituents of several proteins involved in intermediary metabolism, hormone secretion, and the immune system [3] and are required in small amounts in the diet. The effects of Zn, Mn, and Cu deficiencies on bree...

Past research on feed restriction methods with turkey breeder hens has involved the feeding of 1) high-fiber or low-energy diets, 2) low dietary protein, 3) limited quantities of feed, 4) rations on a skip-a-day program, 5) distasteful compounds, or 6) combinations of these methods. In general, feed-restricted turkey breeder hens showed a reduction in BW and a delay in sexual maturity at time o...
