“…Similar results were obtained by Oliveira et al (2003) and Tavernari et al (2008), who used 0 and 20% and 0, 15 and 30% sunflower meal, respectively. Based on performance results, Furlan et al (2001) verified that it is possible to replace up to 30% of soybean meal protein by sunflower meal protein, depending on the market price of sunflower meal at the time of utilization.…”

“…Tavernari et al (2008), using 0 and 20% sunflower meal, concluded that, during the starter and entire experimental phases, feed intake was significantly lower when sunflower meal was used, which may be explained by the high crude fiber and vegetable oil dietary content; however, there was no significant effect on weight gain. Pinheiro et al (2002) observed that the inclusion of 12% sunflower meal in broiler diet did not affect live performance, and that the best economic performance between three and 35 days was obtained when no sunflower meal was included in the diet, and from 36 to 42 days of age, with 4% sunflower meal dietary inclusion.…”

-The objective of the present experiment was to evaluate the inclusion of sunflower meal in diets formulated on total or digestible amino acid basis fed to broilers of 22 to 42 days of age. Nine hundred and sixty birds were distributed in a completely randomized experimental design in a 2 × 2 factorial arrangement (two formulation criteria -digestible or total amino acids; two sunflower meal inclusion levels -0 or 15%), with six replicates of 40 broilers each. Performance (weight gain, feed intake and feed conversion) and data from carcass characteristics (eviscerated carcass and commercial cuts) were evaluated. On day 42, six birds from each pen were sacrificed to determine digesta viscosity, and litter samples from each replicate pen were collected to determine litter moisture. The inclusion of 15% sunflower meal in broiler diets formulated on total amino acid basis worsens feed conversion ratio. Diets formulated on digestible amino acid basis are adequate when alternative feedstuffs, such as sunflower meal, are included. The use of sunflower meal in the diet does not influence carcass and cuts yields, but digesta viscosity increases when 15% of that feedstuff is included in the diet.

“…Contrary to our results, Sherif et al (22) observed no beneficial impacts for enzyme supplementation on protein efficiency ratio. Poultry and monogastric animals do not have an endogenous capacity to digest fiber, and therefore the use of exogenous enzymes is important as they hydrolyze nonstarch polysaccharides that can potentially be used by the animals, improving, for instance, energy use (23).…”

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...

“…Concerning the fiber for broilers, the physical density of the diet can change depending on the fiber content in the diets; the feed intake is decreased due to the high volume that fiber occupies in the digestive tract, which can also interfere with the water retention capacity (SUNDU; KUMAR;DINGLE, 2006). A similar linear decrease in feed intake with increasing SFM levels was reported by Tavernari et al (2008) who tested 0 to 20% SFM dietary inclusion in birds from 1 to 21 d of age. However, in contrast to the current study, Tavernari et al, (2008) reported a positive effect in feed conversion ratio at all growth phases.…”

-This research aimed to evaluate the effects of different levels of sunflower meal (SFM) and the supplementation of a multienzyme complex in the initial diets of broilers on their performance, intestinal morphometry and carcass characteristics. In all, 1100 1-d-old male chicks were distributed in a completely randomized design with 2 x 5 factorial arrangement (with and without a multienzyme supplement and five levels of SFM inclusion -0, 4, 8, 12 and 16%), and five replications per experimental unit. The experimental diets were provided until the chickens were 21-d-old and thereafter all birds received the same diet up to 42 d, to evaluate the possible residual effects of treatments. The SFM inclusion impaired performance from 1 to 21 d of age and the animals that received SFM during the initial phase, failed to recover from the negative effects on performance parameters. The multienzyme supplement improved the intestinal morphometry and was more effective than non-supplemented diets on performance, independent of the SFM inclusion level. The carcass and cuts yield of the wings and leg were significantly affected by the multienzyme supplementation. In conclusion, the SFM inclusion impaired performance variables and intestinal morphometry without affecting carcass yield; however, the supplementation of an enzyme complex counteracted the negative performance and intestinal morphometry effects.Keywords: Alternative food.
