          Abstract

          ABSTRACT. The present study was conducted to evaluation the different levels canola meal (CM) replacement by soybean meal (SBM) in Japanese quails diets on productive performance, egg quality trails and blood parameters including blood protein, minerals concentration, liver enzymes and thyroid hormones. In this study, 160 of Japanese quails in second laying phase from 46 to 56 weeks of age were divided in four treatments with four replicates and 10 quail in each per replicate, on a completely randomized design (CRD).Treatments consisted:T1) control (without CM), T2, T3 and T4) replacing 30, 60 and 90% of SBM with CM respectively. The results were shown no significant variation in body weight between treatments in initial and end of the experiment (p > 0.05). There was significant decrease in feed intake by increasing level of CM (p < 0.05). Results indicated that significant increase in egg production, egg weight and egg mass in the T1 (control group) and T2 (contained 10% CM) (p < 0.05). No significant differences were found in egg quality parameters in the all period of experiment (p > 0.05). However, the egg shell thickness showed significantly decreased with increasing levels of canola meal in the diet (p < 0.05). According to this study results, 30% replacement of SBM by CM in the diet (contained 10% CM) has no adverse effect on quail’s performance.

          RESUMO. Este estudo avaliou a substituição de diferentes níveis de farelo de canola por farelo de soja nas rações de codornas Japonesas sobre o desempenho produtivo, qualidade de ovos e parâmetros sanguíneos, inclusive proteína sanguínea, concentração mineral, enzimas de fígado e hormônios de tiroide. Cento e sessenta codornas japonesas na fase da segunda postura, de 46 a 56 semanas, foram divididas aleatoriamente em quatro tratamentos, com quatro repetições e 10 codornas por repetição. Os tratamentos foram: T1) controle (sem FC), T2, T3 e T4), substituindo 30, 60 e 90% de FS com FC, respectivamente. Os resultados não revelam variação significante no peso corporal entre os tratamentos no início e no final do experimento (p > 0.05). Houve uma redução significativa no consumo de dieta com o aumento de nível de FC (p < 0.05). Os resultados mostram um aumento significativo na produção de ovos, peso de ovos e massa de ovos em T1 (controle) e T2 (com 10% de FC) (p < 0.05). Não houve diferença significativa nos parâmetros de qualidade de ovos durante todo o experimento (p > 0.05). Todavia, a espessura da casca dos ovos reduziu-se significativamente com níveis crescentes de canola na dieta (p < 0.05). Os resultados mostram que a substituição de 30% em FS por FC na dieta (com 10% de FC) não tem efeitos adversos no desempenho das codornas.

          Influence of age on the apparent ileal amino acid digestibility of feed ingredients for broiler chickens

          The apparent ileal digestibility of amino acids in 8 feed ingredients was determined using 14-, 28- and 42-d-old male broiler chickens. The ingredients included three cereals (wheat, sorghum and maize), one cereal by-product (mill run), three oilseed meals (canola, cottonseed and soybean meals) and one animal protein meal (meat and bone meal). Dietary crude protein in the assay diets was supplied solely by the test ingredient. All diets contained 20 g/kg acid-insoluble ash as an indigestible marker, and each diet was offered ad libitum in mash form to 5 replicate pens from 11 to 14 d, 25 to 28 d and 39 to 42 d post-hatching. There were 12, 6 and 6 birds per pen for the 14, 28 and 42 d samplings, respectively. The results suggest that the age of broilers significantly influenced the apparent ileal digestibility of amino acids. The effects, however, varied among amino acids and ingredients. In wheat, the digestibility of most amino acids was higher in 14- than in 28- and 42-d-old broilers. In maize, the digestibility coefficients of amino acids were higher at 28 and 42 d than at 14 d. The digestibility coefficients in maize and wheat at 28 and 42 d were similar. The digestibility of amino acids in sorghum at 42 d was higher than those at 28 d, but similar to those at 14 d except for histidine, lysine, serine and glycine, which were significantly higher at 42 d. Digestibility of amino acids in sorghum was similar between 14 and 28 d except for isoleucine, leucine, phenylalanine, glutamic acid and alanine. The digestibility of amino acids in mill run at 42 d was significantly higher than those at 14 and 28 d. There were no differences in digestibility between 14 and 28 d. In general, the digestibility of amino acids in canola meal, soybean meal and, meat and bone meal was higher at 28 and 42 d compared to those at 14 d, and similar between 28 and 42 d of age. In cottonseed meal, age had no effect on the digestibility coefficient of amino acids, except for lysine and arginine, which increased with age. Analysis of the combined results for the 8 feed ingredients showed that, in general, the digestibility coefficients of amino acids increased with advancing age of broiler chickens.
