“…Our results suggest that chicks held for 36 h were affected earlier/more by stressors and these birds had better FE than birds with access feed immediately after hatch. Overall, mortality rates (data not shown) in the present experiment were found to be similar to some previous studies (Hooshmand 2006;Kidd et al 2007). Moreover, bird losses due to mortality and culling were at low levels, and were not affected by the feeding program or feed supplement.…”

ABSTRACT:A trial was conducted to investigate the effects of a dietary organic acid blend for a period of 35 days on the growth performance, intestinal histomorphology and microflora of male broiler chicks with delayed access to feed. One hundred and ninety two one day old broiler chicks (ROSS 308) were randomly distributed into 4 groups housed in four replicate pens with 12 birds in each. A 2 × 2 factorial design was implemented. Four experimental groups were formed by two levels of dietary organic acid blend supplementation (Control and Fysal Dry ® ) and two periods of delayed feed access (0 and 36 h). At 36 h after hatching body weight and body weight change of chicks were significantly (P < 0.001) lower than groups fed immediately after hatching. Delayed feed access had an adverse impact (P < 0.001) on the body weight and feed consumption of broiler chickens on days 14 and 28. Between the days 28 and 35 of the feeding period, these differences disappeared. The relative weight of gizzard (P < 0.05), pancreas (P < 0.01) on day 6 and intestine (P < 0.05) on day 10, and gizzard (P < 0.01) on day 10 were reduced in birds subjected to delayed feed access. Dietary organic acid blend inclusion increased villus length (P < 0.001), whereas delayed feed access decreased villus length (P < 0.05) and increased the incidence of epithelial degeneration and basal membrane separation of the propria mucosa of villus in the jejenum. A significant decrease in Enterobacteriaceae count (P < 0.01) was noted in organic acid blend supplemented groups on day 25. Pectoral muscle malondialdehyde levels were decreased (P < 0.01) with dietary organic acid blend supplementation at day 10. Delayed feed access significantly increased (P < 0.05) the heterophil:lymphocyte ratio at day 6. Overall, dietary organic acid blend supplementation helped broiler chicks to develop a healthier intestinal microflora and this may, in turn, inhibit the delayed feed access-induced increase in malondialdehyde in the early growing period. However, the inclusion of organic acid blend to broiler diets may not be a protective management practice in preventing delayed feed access-related growth depression of broiler chickens.

“…According to Murakami et al , when feed consumption starts soon after hatch, the nutrients provided by the feed are complementary to the yolk nutrients. Thus it has been stressed by several researchers that hatchery feeding is of great importance . Hatchling supplements and pre‐starter feed are easily added to chick trays in the chick‐holding rooms in commercial hatcheries.…”

“…Abed et al confirmed that immediate access to feed and water after placement will ensure the optimal performance of broiler chicks at market age, and that broiler chicks do not have enough potential to fully compensate for growth retardation caused by long‐term deprivation of feed and water during the neonatal period. However, Kidd et al reported that a 5 h hatchery feeding regimen of crumbled starter diets varying in amino acid concentrations and moisture did not affect the live performance or yield of broilers when reared to 2 kg.…”

In ovo supplementation of poultry embryos was first reported several decades ago, but it is only recently that concerted research has been directed at developing the technology for this process to be routinely used by the poultry industry. Although the technology of in ovo feeding was patented more than 10 years ago, it has not been widely adopted by the poultry industry. This review examines the early development of the enteric system of the poultry embryo; defines and distinguishes between in ovo feeding and in ovo nutrient administration; highlights the importance of early feeding of the chick; and discusses the development of in ovo feeding technology and its effects on hatchability, growth, gut health and immune response of chicks. The range of possible nutrients that can be administered is also explored. The limitations associated with embryo development and nutrient metabolism are highlighted, leading to the prediction of the future role of in ovo feeding in the poultry industry.

“…Although newly-hatched chicks cannot make use of fat, Turner et al (1999) reported a commercial synthetic fat (with concentration of medium chain fatty acids containing 75% C 8:0) can in fact be maximally absorbed, utilized and be a valuable energy source for newly-hatched chicks. Kidd et al (2007) reported that a 5-h hatchery feeding regimen of crumbled starter diets varying in amino acid concentration and moisture used in their experiment did not affect live performance or yields of broilers marketed to 4.6 lb (2 kg).…”
