“…There are limited data on the influence of the dietary inclusion of sunflower meal on broiler gut viscosity. Brazilian research studies showed that 15% inclusion of sunflower meal in the diet caused a statistically significant increase in viscosity (Araújo et al, 2011). However, the inclusion of sunflower meal up to 35% in broiler diets did not increase viscosity either in the jejunum or in the ileum.…”

Enzyme supplementation of diets enhances broiler performance by improving some of the basic production parameters such as average feed intake, feed conversion ratio, or average weight gain. The enzyme NSPase is commonly used in broiler diets containing high levels of viscous cereals such as barley, oat, wheat, or sorghum. The use of NSPase in diets with different levels of sunflower meal has been not been extensively explored. The experiment was carried out to evaluate the effects of the inclusion of sunflower meal levels in grower and finisher broiler diets supplemented or not with enzymes (cellulase, β-glucanase, and xylanase) on broiler performance, intestinal function, and carcass traits. A completely randomized experimental design, with 3*2 factorial arrangement with five replicates, was applied (1200 Ross 308 broilers). Sunflower meal inclusion and enzyme supplementation started in grower phase. Broiler performance significantly improved in grower phase (weight gain and feed conversion ratio) by enzyme supplementation, while the effect of sunflower meal was evident in finisher phase, when it significantly reduced weight gain. Sunflower meal increased ileal viscosity, and the interaction between diet and enzyme supplementation was statistically significant. Maltase activity was reduced with sunflower meal dietary inclusion, while enzyme supplementation had no effect either on maltase or sucrase activity. There were no any effects of sunflower meal inclusion with or without enzyme supplementation on carcass characteristics. It can be concluded that high inclusion of sunflower meal in broiler diets may impair broiler performance, but this may be overcome by enzyme supplementation. The effect of enzyme supplementation more evident in the grower phase than in the finisher phase.

“…Salari et al (2009) found that the percentages weight of gizzard, breast, thigh, gastrointestinal tract and abdominal fat were not affected by dietary treatments which contained different levels of full fat sunflower seed; while, liver weight % was decreased significantly (P<0.05). Araújo et al, (2011) pointed out that use of sunflower meal up to 15% in the broiler diets did not influence growth performance and carcass and yields during period 22 to 42 days of age. Increasing dietary inclusion of SFM with enzyme blend supplementation reduced body weight gain and deteriorated feed conversion.…”

| The benificial application of untraditional feedstuffs such as sunflower meal (SFM) in animal and poultry nutrition in developing countries has received considerable attention. SFM is a by-product of sunflower oil industry, and has been increasingly added to animal and birds diets. Moreover, SFM is potentially one of the most important protein source in the world. Nowadays, it is well known that feed represents the main cost of animal and poultry production and accounts about 75% of the total cost. The increasing feed ingredients price of poultry nutrition caused to look closely at agricultural by-products which are less cost than traditional ingredients. Thus, the waste residues of crops, vegetables and fruits after harvesting and processing could be used as sources of protein, energy and other nutrients in feeding animals and poultry. Reports from variuos laboratories on the using SFM as feed ingredient for poultry are discussed in this review. Based on the findings presented, SFM is an acceptable feed componentof poultry rations and can be fed at 25% in broiler and 20% in layer diets. However, replacement of soybean meal (SBM) with SFM may affect dietary inclusions of essential amino acids, and use of synthetic lysine may need to be increased. The high levels of SFM in poultry diets can be used successfully with appropriate diet formulation adjustments for energy and amino acids particularly lysine and methionine. This compilation with its valubale information would be beneficial for researchers, chemists, feed and food industry, and certainly could help to promote the usage of SFM in poultry production.

“…Enzymes are proteins capable of catalyzing chemical reactions in the digestive tract of animals, facilitating and promoting the digestion of nutrients for absorption (ARAÚJO et al, 2011). The use of enzymes in the initial phase of animal development may favor the utilization of dietary nutrients because the digestive organs are undergoing development and are not able to secrete large quantities of endogenous enzymes (MONTEIRO et al, 2006).…”

-This study aimed to evaluate the performance, carcass yield and intestinal morphometry of 1-to 21-day-old broiler chickens fed a diet containing increasing levels of sunflower cake, supplemented with or without an enzyme complex (EC). We used 1200 Cobb 500 birds, which were distributed in a completely randomized design in a 2x5 factorial scheme and five levels of sunflower cake inclusion (0, 5, 10, 15, and 20%) in diets supplemented or not with EC. Each treatment consisted of 5 replicates. Animals were fed the experimental diets from 1 to 21 days of age and from 22 to 42 days all birds received the same feed based on corn and soybean meal. There was no interaction between the level of sunflower cake inclusion and presence of EC. From 1 to 21 days of age, the weight gain, final weight, and feed intake linearly decreased (P<0.05) with increasing sunflower cake inclusion level. At 42 days old, after animals consumed diets based on corn and soybean meal (from 22 to 42 days), the levels provided least 21 days did not influence the performance results. Animals receiving the EC in the first phase showed better results at the end of the experiment (P<0.05). Up to 21 days old, carcass yield decreased, and abdominal fat increased with the sunflower cake inclusion. The addition of EC in the diet improved the thigh, breast and carcass yield. Intestinal morphology after 21 days revealed that the three segments of the intestine had at least one type of change, such as a decrease in villus height and increase in crypt depth, with increased level of sunflower cake in the diet, affecting performance.Keywords: Alternative food.
