The French cattle tracing system results from a long evolution, which began in the mid sixties for cattle selection purposes. In addition to its main objective which is cattle tracing and sanitary uses, the system is widely used by many breeder organisations for very different uses: parentage recording, performance recording, herd book keeping, breeding value calculation and animal marketing. T...
The influence of timing of artificial insemination on fertility and hatchability of breeder hens was carried out by inseminating breeder hens at 10:00 hr and 15:00 hr with pooled semen from Shikabrown White breeder cocks for four weeks. Fertile eggs were collected two days after the first insemination and stored at a temperature of 16 C for seven days before incubation. Fertility was higher (P ...
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...
Life history theory predicts that the amount of resources allocated to reproduction should maximize an individual's lifetime reproductive success. So far, resource allocation in reproduction has been studied mainly in females. Intraspecific variation of endogenous energy storage and utilization patterns of males has received little attention, although these patterns may vary greatly between ind...
A high incidence (about 70%) of alteration in endometrial epidermal growth factor (EGF) profile, i.e., loss of 2 peaks on days 2-4 and 13-14, has been linked to a reduced fertility in multiparous repeat breeder Holstein cows. However, the EGF profile in Holstein heifers and other breeds (types) of cattle has not been investigated. In study 1, EGF concentrations were determined using endometrial...

Recent research to define a measure of chick quality has evaluated the effects of incubation conditions, breeder age and genotype on progeny growth and survival. Nutritional research has focused on defining the optimum concentration of maternal dietary nutrients for progeny growth, mortality and immune status. There is a research requirement to bring these two areas together to better understan...
