“…The latter results agreed with those from Mushtaq et al (2007) who found no significant difference in antibody titer against NDV of broilers fed diets containing 20 or 30% CM. The measurement of serum GOT and GPT activities, indicative of tissue damage in bird, is a valuable tool to determine a safe inclusion level for non-conventional feedstuff (Diaz et al, 2003).…”

“…Jung et al (2012) found that addition of CM at the level of 7.5% in diet significantly (p<0.05) decreased the carcass yield and marginally (p>005) breast meat yield in broiler chickens. Mushtaq et al (2007) also reported that the breast meat was reduced in broiler chickens fed a diet containing 30% CM diet with only 0.8% available lysine. The yield of breast meat is considered sensitive to the quantity and composition of dietary amino acids, and thus careful consideration should be taken when diet with high levels of CM are fed.…”

KeywordsBroiler chickens, canola meal, growth performance, meat quality. ABSTRACTThis experiment was conducted to evaluate the dietary supplementation of canola meal (CM) on the growth performance, carcass characteristics, antibody titers against Newcastle disease virus and Infectious bronchitis virus, and blood profiles of broiler chickens. In total 600 day-old feather-sexed Ross male broiler chicks were randomly assigned into five treatments with six replicates of 20 birds each for 35 days. Treatments consisted of five experimental diets containing 0 (control), 3, 5, 10, or 15% canola meal (CM). Final body weight (BW) was not affected by the dietary treatments. Daily BW gain (DWG) and feed intake linearly decreased as dietary CM inclusion increased during the starter phase (p<0.0001), but not during the grower and total rearing periods. Chicks fed the diet with 15% CM presented the lowest DWG during the starter phase. Breast meat yield of CM-fed chicks linearly decreased as CM inclusion level increased (p=0.0014). Dietary CM supplementation did not influence organ relative weights, except for the spleen, meat quality, or blood profile. The results suggest that the CM may replace soybean meal (SBM) with no detrimental effects on overall growth performance or physiological responses of broiler chickens. However, it is recommended that supplementing excess amount of CM into broilers' diet should be taken into account in practical diet formulation as it could impair growth performance at early age and lower breast meat yields.

The influences of feeding broilers on graded inclusion of sunflower meal with or without Avizyme on growth, protein and energy efficiency, carcass traits, and nutrient digestibility

IntroductionIt is well known that prices of poultry meat are lower than those of other meats and this created a high demand for poultry meat in many countries around the world within the last few years. Many factors affect costs of poultry production, such as feed price, feed fed amount, crude protein content of feed, and the biological value of nutrients. Because of the limited resources of feedstuffs in developing countries and increasing demand for soybean meal (SBM) as a main source for crude protein, feeding costs have tended to increase (1). The use of untraditional feedstuffs in poultry diets has received great attention in developing countries. Sunflower meal (SFM) is defined as a by-product of the sunflower oil industry (2). The chemical composition of sunflower meal mainly depends on some factors like the seed, the method of processing, and the degree of decortication. SFM contains about 33%-37% crude protein and 18%-23% fiber contents. The meal is a mixture of hulls and kernel in a ratio about 40%/60% as described by Lević et al. (3). The major challenge of the inclusion of SFM in diets of broilers is its high content of fibers (4), which has negative impacts on growth and carcass traits. To solve this problem, certain synthetic enzymes like phytase and β-glucanase could be added to broiler diets having SFM to help in the digestion of fibers and to decrease their negative effect on growth parameters of broiler chickens. Lipiec (5) stated that SFM can be successfully used in the nutrition of monogastric animals at levels of 50-150 g/kg diet. Alagawany et al. (6) reported that there are many factors encouraging the use of SFM in poultry nutrition, like its cheap price compared to SBM and being free from antinutritional factors and toxic molecules. The aforementioned authors reported that SFM as an alternative feedstuff could be utilized profitably at levels of 200 g/kg of broiler diets without any harmful effects on growth and carcass yield. Using enzymes could be a practical way to enhance performance and improve utilization of higher levels of agroindustry Abstract: The present study aimed to investigate the substituting effect of sunflower meal (SFM) for soybean meal (SBM) with or without supplemental Avizyme on growth performance, protein and energy efficiency ratios, carcass traits, and nutrient digestibility of broiler chickens. A 4 × 2 factorial design experiment was conducted with four levels of SFM replacing SBM (0%, 25%, 50%, 75%) and two levels of supplemented Avizyme (0 or 0.1 g/kg diet). Results revealed that increasing SFM substitution for SBM up to 50% was associated with an increase in body weight (P < 0.01). Daily weight gain was statistically (P < 0.01) enhanced with increasing SFM up to 50% through 22 to 42 and 7 to 42 days of age. Feed conversion ratio improved (P < 0.01) in groups given SFM at 25% and 50% compared to the control. No carcass values were affected by SFM inclusion or Avizyme. The inclusion of 25% or 50% SFM increased (P < 0.01) protein efficiency at periods of 7-21 an...

The objective of this study was to evaluate the effects of enzyme supplementation on the nutrient, amino acid, and energy utilization efficiency of citrus pulp and hawthorn pulp as unusual feedstuffs in Linwu ducks. Forty ducks were assigned to each treatment group and fed diets with or without complex enzyme supplementation. All birds received the same quantity of raw material (60 g) via the force-feeding procedure. With the exception of leucine and phenylalanine, amino acid concentrations in hawthorn pulp were twice those in citrus pulp. Enzyme supplementation significantly increased apparent dry matter digestibility (ADM) of citrus pulp (P < 0.05), but had no significant effects (P > 0.05) on the apparent and true utilization rates of other nutrients, apparent metabolizable energy (AME), or true metabolizable energy (TME), from citrus pulp and hawthorn pulp by Linwu ducks. However, enzyme supplementation significantly increased (P < 0.05) apparent gross energy, true gross energy, AME, and TME of hawthorn pulp for Linwu ducks. There were no differences in the apparent and true utilization rates of amino acids from citrus pulp (P > 0.56) between the groups, with the exception of arginine (P < 0.05). There was an increasing trend in the apparent and true utilization rates of alanine (P = 0.06) and tyrosine (P = 0.074) from citrus pulp with enzyme supplementation. The apparent and true utilization rates of threonine in hawthorn pulp were increased significantly (P < 0.05) following enzyme supplementation. The addition of exogenous enzymes improved the forage quality of citrus pulp and hawthorn pulp, which represent potential feed resources for husbandry production.
