“…Sterling et al (2002) found that young chicks, beside the high nutritional requirements of protein and essential amino acids, are more sensitive to the presence of antinutritional substances in feed. The physiological background might be related to incomplete development of the gastrointestinal tract (Wijtten et al, 2004), which affects the digestion efficiency in the consecutive growing phases (Vieira and Moran, 1999;Ravindran, 2002). Such findings agree with our results where the depressive effect of the faba bean in starter diets was partially compensated in the following growing phases.…”

This paper assesses the effect of faba bean (Vicia Faba minor), in partial substitution of soybean, on productive performance, carcass and meat traits of slow-growing chickens readed under the organic method. Faba bean was used in both starter (1-21 d) and growing/finisher diets (22-120 d). One thousand birds were fed two different diets containing respectively, soybean or faba bean as the main protein source for the entire rearing period. The birds of each group were slaughtered at 120 d of age. The productive performance of group F was the worst, with a higher mortality rate, indicating that faba bean diets are not able to cover the nutritional requirements of birds mainly in the first rearing period. The main carcass and meat qualitative traits, were not affected by the treatment, whereas minor modification regards saturated and monounsaturated fatty acids.

“…The post-hatching chick needs to adapt from maternal nutrition to exogenous feed, when nutrient supply changes from the high fat yolk sac to a high starch feed, and this process may take several days (Vieira & Moran, 1999). During this period, the secretion of endogenous enzymes also changes according to the composition of the exogenous feed, together with an increase in digestive organ size to rapidly accommodate the increase in feed intake .…”

“…Segundo Nir & Levanon (1993), a perda de peso imposta aos pintinhos que receberam ração após 40 a 52 horas de eclosão (12 e 24 horas pós-alojamento) atrasa de 1 a 2 dias, respectivamente, o tempo para que as aves atinjam o peso de abate das aves alimentadas logo após a eclosão. Atrasos de 24 horas no alojamento determinam perdas de peso inicial aos 49 dias de 110 g (Vieira & Moran, 1999a).…”

RESUMO -Dois experimentos foram realizados para determinar o valor nutricional do ovo desidratado (OD), o efeito do tempo de jejum pós-eclosão (TJPe) e a inclusão do ovo desidratado em rações para frangos de corte. No primeiro experimento, 120 pintos de corte machos, linhagem Ross-308, foram alojados em delineamento inteiramente casualizado, com três tratamentos e cinco repetições de oito aves. As coletas de excretas foram realizadas no período de 24 a 29 dias de idade, pela manhã e à tarde. No segundo experimento, um lote misto de 810 pintos da linhagem Cobb-500, com peso vivo inicial 33,41 ± 0,53, foi alojado em boxes de 1,0 × 1,5 m. O delineamento experimental utilizado foi o inteiramente casualizado com 9 tratamentos e 6 repetições de 15 aves, em esquema fatorial 3 × 3, com três níveis de ovo desdratado (0, 2 e 4%) e três tempos de jejum pós-eclosão (28, 40 e 52 horas), correpondentes a 0, 12 e 24 horas de jejum pós-alojamento, respectivamente.O ovo desidratado apresentou 51,54% de PB e 4.278 kcal EMAn. Na fase de 1 a 7 dias, o peso vivo, o ganho de peso e o consumo de ração entre as aves submetidas a jejum de 40 e 52 horas foram inferiores aos daquelas alimentadas mais cedo (às 28 horas do tempo de jejum pós-eclosão), enquanto as aves submetidas a 52 horas de jejum pós-eclosão (24 horas de jejum pós alojamento) apresentaram os piores resultados. O nível de 4% de ovo desidratado na ração pré-inicial melhorou o peso vivo no segundo e terceiro dia de idade dos pintinhos. No período de 1 a 21 dias, o ovo desidratado pode ser utlizado na alimentação de frangos, pois não prejudica o desempenho das aves.Palavras-chave: alimento alternativo, desempenho, desenvolvimento inicial, valor nutritivo Effect of post-starvation hatching time, energy levels and addition of dried egg in pre-initial and initial diets for broiler chicksABSTRACT -Two experiments were carried out to determine the nutritional value of the dried egg (DEGG), and the effect of the post-starvation hatching time (PSHT) and the inclusion of dried egg powder in the diet of broiler chicks. In experiment 1, 120 male Ross-308 broiler chicks were housed according to a completely randomized design into three treatments and five repetitions of eight birds each. Excreta collection was daily performed from 24 to 29 days of age in the morning and afternoon. In experiment 2, a sex-mixed batch of 810 Cobb-500 chicks was used. Initial weight was 33.41 ± 0.53 g, and the chicks were housed in pens measuring 1.0 × 1.5 m. A completely randomized experimental design was used with nine treatments and six repetitions of 15 birds each, according to a 3 × 3 factorial of three DEGG levels (0, 2 and 4%) and three PSHT (28, 40 and 52 hours), corresponding to: 0, 12 and 24 hours of starvation after housing, respectively. DEGG showed 51.54% of CP and 4,278 kcal AMEn/kg. From 1 to 7 days of age, the birds submitted to starvation for 40 and 52 hours showed lower live weight, weight gain and feed intake when compared to birds fed sooner (at 28 hours PSHT). The poorest performance wa...
