“…Whitehead et al (1985) observed low levels of biotin in hen plasma, egg yolk and chick plasma in food-restricted broiler breeders at 31 weeks compared with the same birds at 41 weeks of age. It had previously been shown that biotin in hen plasma increased rapidly as birds approached sexual maturity (Whitehead, 1984).…”

Centre, Roslin, Midlothian EH25 9PSTo interact is to act reciprocally, and in the context of nutrition and reproduction in birds may be represented by the relation : Reproduction, 'NutritionInteraction from left to right, i.e. reproduction -+ nutrition, dominates the study of nutrition in domestic animals. Reproduction is thought of as generating a requirement for nutrients, which if not supplied results in less than optimum (usually maximum) production. In commercial systems the size and reproductive potential and therefore the nutrient requirements of birds are frequently changed by restricting growth during the rearing period. In table-egg-laying strains (layers) the change is not large but in broiler breeder hens the effect is dramatic. This is an example of nutrition -+ reproduction interaction and will be discussed later in this paper.There are four major components in the reproductive life-cycle of the bird (Fig.

“…A high biotin intake from the diet reduced its transfer rate to eggs, but more than 50% of ingested biotin was transfered to eggs ( 27 ). In particular, a large amount of biotin accumulated in the yolk, but normal embryonic growth was not observed at a yolk biotin concentration of Ͻ 50 ng/g, and 150 ng/g biotin or more was necessary to maintain normal embryonic growth ( 28 ).…”

Summary It is well known that biotin deficiency causes morphological anomalies in hatchlings of fowl. An abundance of biotin in the yolk, therefore, is greatly required for maintaining reproductive functions. Although there is growing evidence for the molecular significance of the vitamin in the processes of the reproductive system in mammals, little is known about its use and roles in fowl's yolk. This review focuses on studies on the roles of biotin in the ovarian follicles and embryos of domestic fowl. Recent studies from our laboratory showed an analysis of the mechanism of biotin supply from the maternal body to follicles, or the yolk using the eggs of domestic fowl. In growing ovarian follicles, biotin was incorporated into the follicles, particularly in a large amount immediately before ovulation. Biotin incorporated from the early stage to the growth stage of ovarian follicles was stored in the protein-binding form and became free biotin again immediately before ovulation. This may be because the biotin necessary for the maintenance of embryonic growth and development should be used immediately after fertilization. In embryos, free biotin in the yolk increased shortly after fertilization. A large amount of free biotin was incorporated into the embryo at the age of 3-4 d. Biotin supply to the embryo differed among embryonic growth stages and organs, suggesting involvement in the formation of each tissue and organ. Thus, a large amount of biotin was utilized for embryonic growth, suggesting its important role in normal embryonic growth. These findings show that biotin is an essential nutrient and may play a major role in the normal morphogenesis of embryos in domestic fowl.

“…The biotin content of eggs increases with incremental increases of dietary biotin intake (Couch et al, 1949;Whitehead et al, 1985;White et al, 1987;Robel, 1988). Because there is a positive relationship between dietary biotin and the amount of biotin in the egg, on a practical basis, the use of higher levels of supplemental biotin would appear to benefit hatchability.…”

Two experiments were conducted with Large White Turkey hens in individual cages to determine the value of supplemental biotin for increasing hatchability. No differences were observed for 7-day embryo deaths between treatments in both experiments. In the last two-thirds of the production cycle in both experiments, eggs from hens fed 520 micrograms and 623 micrograms/kg had the fewest embryonic deaths during Days 7 to 28 of incubation. Concentrations of biotin in egg albumen increased with incremental dietary biotin levels, but egg yolk concentrations were stable. About 38 micrograms of biotin per egg (82 g) produced highest embryo survival. Regression analysis, based on average percentage hatchability at the treatment levels for both experiments, revealed no hatchability response for Period 1 (first third of production cycle) from biotin. However, the dietary biotin level for hatchability increased with maternal age, which ranged from 500 to 800 micrograms/kg for Periods 2 (second third of production cycle) and 3 (last third of production cycle), respectively.
