Fast Growth Rate

Continuous genetic selection and improvement in nutrition have led to a very fast growth rate in modern strains of broiler chickens. Metabolic disorders such as ascits, sudden death syndrome and leg problems are related to a rapid early growth rate in poultry, especially in broilers, and their incidence can be decreased by slowing early growth. The use of management tools to reduce metabolic disorders that rely primarily on decreasing feed consumption, The feed restriction programs is on of the main techniques in growth curve manipulation for increasing production efficiency in broiler chicken in alleviate the incidence of some metabolic disorders and can be used to reduction the unfavorable effects of fast growth rate in broiler chicken production industry, and could be profitable in broiler chickens production efficiency. This article implicated on new findings in about different feed restriction programs effects on these problems in broiler chickens.

Abstract The aim of investigations was the estimation of nutritional value of currently cultivated yellow lupine cultivars in raw and extruded form, and their usefulness for broiler chickens. Two experiments were conducted with male Ross 308 chickens. In a digestibility trial 60 fifteen-day-old birds were randomly assigned to three dietary treatments (20 replications in each). Birds were kept in individual pens. Digestibility was calculated using the difference method. From day 16 to 21, diets contained lupine meal in raw or extruded form and the basal diet in the ratio 20:80. Subsequently, the total digestibility of dry matter and crude fat, also apparent nitrogen retention and AMEN value of lupine seeds were determined on chickens fed different forms of lupine. The ileal digestibility of crude protein and amino acids of lupine seeds was also analyzed. In the second experiment the one-day-old birds were randomly assigned to ten dietary treatments (10 replications in each) and were fed diets with increasing amounts of raw or extruded lupine from 10 to 30%. The chickens in control treatments were fed a diet without lupine. Extruded yellow lupine meal was characterized by lower phytic P content in comparison to raw yellow lupine meal. The content of remaining ingredients and antinutritional substances was similar. Yellow lupine seeds post extrusion were characterized by better total crude fat digestibility, nitrogen retention and AMEN values, compared to raw seeds. Higher ileal digestibility was confirmed in numerous amino acids, except lysine, threonine and valine (P≤0.05). By feeding the broilers with diets consisting of 10 to 30% of lupine seeds post extrusion (experiment II), improved apparent fat digestibility, apparent nitrogen retention and AMEN values were achieved in young chickens (P<0.01). Using 10 and 20% of lupine in the diets showed significant positive effects of extrusion on body weight gains, feed intake and feed conversion rate. The performance indices of chickens were drastically decreased by use of 25% ratio of both raw and extruded yellow lupine in the diet. This effect was heightened by a 30% share in feed mixtures.

A study was conducted to examine the effect of starch and nitrogen digestion kinetics on broiler performance using sorghum-based diets as a model. Three sorghum varieties with red, white and yellow pericarps and three feed forms, mash, intact pellets and reground pellets, constituted a 3 × 3 factorial array of dietary treatments. Starch and nitrogen digestion kinetics were determined using an exponential mathematical model to relate digestion coefficients in the proximal jejunum, proximal ileum and distal ileum with mean retention times in each segment. There were interactions between sorghum variety and feed form for starch and nitrogen digestion kinetics. Steam-pelleting at a conditioning temperature of 90°C (unprocessed mash versus reground pellets) substantially influenced starch digestion rate in red and yellow sorghum-based diets, but not in white sorghum-based diets. Alternatively, with nitrogen digestion rate, there were no significant differences in yellow sorghum-based diets between feed forms but there were in red and white sorghum-based diets. The digestion rate of starch was more rapid than nitrogen, especially in the proximal jejunum. Starch digestion rates were significantly correlated with nitrogen retention but this was not the case with nitrogen digestion rates. The rate of glucose absorption from predicted glycaemic indices was highly correlated with enhanced feed efficiency. Thus this study demonstrates that even under ad libitum feeding regimes, kinetics of starch and protein digestion regulated feed efficiency and nitrogen retention in broiler chickens. The dynamics of starch and protein digestion were more accurate indicators of feed efficiency and nitrogen retention than apparent ileal starch and nitrogen digestibility.

A biological experiment of 160 day old chicks for six weeks was undertaken with completely randomized design (CRD) divided into five treatments, each consisting of 4 replicates and 8 chicks in each replicate. Five experimental diets as per ICAR (2013) were prepared by incorporating rice distillers dried grains with solubles (rDDGS) at inclusion level of (0, 7.5, 10.0, 12.5 and 15.0%). Chemical analysis revealed that rice DDGS on as such basis is high in both crude protein 44.68% and gross energy 4232 kcal/kg. In vitro pepsin-pancreatin digestibility (IVPPD) of rDDGS was found 79.81%. At the inclusion level of 7.5, 10 and 12.5 %, growth performance and nutrient utilization did not show any significant (P>0.05) difference as compared to control but at 15% rDDGS inclusion level, growth performance (body weight gain, feed intake and FCR) and nutrient utilization (dry matter and energy metabolizability, nitrogen retention %) were significantly (Pless than0.01) lower in 15% rDDGS (T5) group as compared to control (T1) and other dietary treatments. Carcass traits did not show any significant (P>0.05) difference between control and other dietary treatments. Cost of production per kg live weight and meat yield were significantly (Pless than 0.01) lower in 7.5 % and above rDDGS levels. Thus, it is concluded that rDDGS can be safely incorporated in broiler chickens diets up to the inclusion level of 12.5% as alternate protein meal for economic broiler production.

As production of European soybeans is expected to grow, optimal processing conditions need to be ensured for small and heterogeneous batches of soybeans. The effect of different soybean varieties, as well as heat treatments, on the growth performance and nutrient digestibility in broiler chickens was investigated. Two varieties, regarded as heat stable and heat labile after preliminary experiments, were partially de-oiled and thermally processed at 110 °C for 20 min and 120 °C for 20 min. The resulting soybean cakes were integrated into a mash diet and subjected to a 36-day long feeding experiment. A total of 336 one-day-old broiler chickens were divided into 24 pens, resulting in 6 replicates per treatment. With application of the 110 °C treatment, analysis of soybean cakes showed that the commonly required reduction in trypsin inhibitor activity (TIA) was only reached with one soybean variety. The higher processing temperature of 120 °C ensured sufficient TIA reductions in both soybean varieties. Elevated TIA concentrations resulted in decreased growth performances (p < 0.05) of the chickens, whereas no negative effect from overheating on growth performance appeared. Total-tract nitrogen retention (p < 0.05) and pre-caecal digestibility of several amino acids (p < 0.10) decreased with higher processing temperatures but had no negative effects on growth performance. In conclusion, the results indicate that processing conditions adjusted to the different varieties are essential to ensure optimal product quality.
