“…Some studies show the importance of nutrition immediately after hatching (Halevy et al, 2000;Pophal et al, 2004). In one study, broilers fed CP-deficient diets presented better BWG and FCR when 1% Lys and 0.5% Met were supplemented to the diet containing 15% CP.…”

Four Nutritional Programs (NP) used in the Brazilian poultry industry were tested in two broiler strains (Cobb 500 and Ross 308). NP varied in the concentrations of their main essential amino acids (AA) and were classified as Low, Regular, High and Mixed (high AA concentrations up to 21 days and regular concentrations after that). Minimum digestible Met+Cys/Lys, Thr/Lys, Arg/Lys, Ile/Lys, and Val/Lys ratios were 0.74, 0.64, 1.05, 0.65 and 0.75, respectively, in all NP, and no minimum amount of CP was fixed. There were no interactions between strain and NP for any of the evaluated responses. From 1 to 47 days of age, birds fed the Low NP presented lower average body weight and body weight gain (BWG). The high NP allowed for better feed conversion ratio (FCR), followed by the Regular and the Mixed NP. Ross 308 broilers were heavier, presenting worse FCR due to higher FI. Birds fed the High NP had lower carcass yield than those fed the Low NP. The Low and Regular NP had lower costs per WG when compared with the High NP. Low and Regular NP presented higher gross margin returns compared with the High NP. The Regular and Mixed NP are the most recommended, presenting intermediate performance and higher economic returns.

“…This eliminates a very critical period of the life of the chicks during which the residual vitellus (approx. 15% of body weight at hatch) is resorbed, the digestive tract starts a tremendous and essential development (Noy and Sklan, 1997) and most regulatory metabolic loops, including those involved in muscle satellite cells proliferation, are completed (Halevy et al, 2000;Bigot et al, 2001).…”

The carry-over effect of a pre-starter diet (0 to 3 days of age) deficient in lysine on subsequent growth and body composition (3 to 10 days) was examined in two experiments on male broiler chicks raised in cages. In experiment 1, lysine deficiency was applied from 3 to 10 days after providing a balanced pre-starter control feed (Dþ, 1.40% lysine) or a lysine deficient feed (D2) during the first 3 days. Three levels of deficiency (A ¼ 0.63%, B ¼ 0.72%, C ¼ 0.82%) were tested. Growth and feed intake were higher in Dþ than in D2 chicks ( P , 0.001). However, the feed conversion ratio from 3 to 10 days of age was higher in Dþ chicks ( P , 0.001); pre-starter and starter feeds interacted ( P , 0.04) with the feed conversion of treatment D2/A ¼ 2.07 being better than treatment Dþ/A ¼ 2.61 ( P , 0.05). This suggests that chicks deficient from hatching exhibit a relatively lower sensitivity to lysine deficiency than chicks started on a control diet. In experiment 2, performance, slaughter parameters and body composition were analysed at 3 and 10 days of age, in chicks having received a lysine deficient feed (D0, 0.72% lysine), a control feed (Dþ, 1.40% lysine) or having been pair fed with control feed adjusted to D0 intake (PF) from 0 to 3 days of age, and then fed D0 ad libitum from 3 to 10 days of age. At 3 days, PF chicks had a higher body weight ( P , 0.05) than D0, and thus a better feed conversion. Body composition in relative values was little or not affected by dietary treatments, but the breast muscle weight at 3 days was higher in Dþ and PF chicks compared with D0 ( P , 0.05) and this effect was even accentuated at 10 days of age. The present work confirms that early nutrition can have subsequent consequences on the adjustment of fast growing broiler chicks to their nutritional conditions. It also suggests that breast muscle development is a more reactive parameter than whole body composition in this kind of experiments.

“…Satellite cell mitotic activity is the highest in the perinatal period and decreases with birds age (Velleman, 2007). As mentioned earlier, delay in feed access decreases satellite cell mitotic activity when compared to their fed counterparts (Halevy et al, 2000;Mozdziak et al, 2002;Moore et al, 2005). Therefore, in ovo feeding may induce proliferation of myoblasts during embryonic development and could be responsible for a higher number of satellite cells in early post-hatch development.…”

In a commercial hatchery, chicks (or poults) hatch over a 24-48 hour period. All chicks remain in the incubator until the majority of the chicks have emerged from the shell. Once removed from the incubator, the newly hatched chick has to undergo several hatchery treatments and is then transported before being placed on the broiler farm. This means that, under practical conditions, chicks are deprived of feed and water for up to 72 hours. In addition, the time of hatch within the hatching window and the spread of hatch cause variability in the amount of time that chicks are feed deprived. Literature on feed deprivation after hatch clearly demonstrates the detrimental effects of any delay in feed access on performance of the chicks with respect to growth, immune system activation, digestive enzyme stimulation and organ development. Improved management strategies, such as shortening the hatching window or the time to first feeding by specific management measures, provide an alternative in dealing with the negative effects caused by a delay in feed access. The development of pre-starter diets that better meet the needs of the newly hatched chicks or in ovo feeding to bridge the gap between hatch and first feeding provide other alternatives in overcoming these problems. However, speculation remains regarding the importance of in ovo or early feeding, or whether the in ovo or early feeding itself is responsible for the beneficial effects reported. The aim of the following review is to discuss the current status of research into early feeding and to stimulate future and further research regarding these topics.
