“…Nevertheless, the use of SFM in poultry diet is limited by variations in its chemical composition. The two main components that restrict its use are its high fibre and low lysine contents (Rezaei & Hafezian, 2007;de Morais Oliveira et al, 2016). One of these issues may be overcome by reducing the fibre content of SFM.…”

This study was designed to evaluate the impact of graded replacements of soybean meal (SBM) with low-fibre sunflower meal (LF-SFM), with and without phytase supplementation, on growth performance, carcass traits, and plasma profile of broilers. A total of 800 mixed sex one-day-old broiler chicks (Cobb 500) were randomly assigned to eight dietary treatment groups (five replicates each) in a 4 × 2 factorial arrangement, including four levels of LF-SFM (0%, 25%, 50%, and 75% to replace SBM) and two levels of microbial phytase (0 or 0.2 g/kg diet). Feed conversion ratio (FCR), and bodyweight gain (BWG) were decreased significantly if LF-SFM replaced more than 25% SBM. There was no significant effect between the interaction of the main factors (LF-SFM × phytase) on growth performance during the starter, grower, finisher and the overall period. The addition of phytase had no beneficial effects on performance traits. Carcass traits were not influenced by feeding LF-SFM or enzyme addition. However, increasing the level of LF-SFM (50% and 75%, respectively) in diets reduced the abdominal fat, whereas the weight of the small intestine was increased. Plasma metabolic profile was not affected by LF-SFM levels in broiler diets, except for high-density lipoproteins cholesterol (HDL-C) and total cholesterol (T-Cho), which were not affected by the dietary enzyme. It is concluded that the diets with LF-SFM levels up to 25% generated growth performance and carcass traits comparable with the diet that contained SBM.

“…Sunflower contains about 45% of oil and a valuable amount of protein and B-complex vitamins. However, the use of SFM in poultry diet is limited by variations in its chemical composition and the two main components restricting its use are high fiber and low lysine contents (Rezaei & Hafezian, 2007;De Morais Oliveira et al, 2016). Fiber of SFM has been shown to mainly consist of non-starch polysaccharides (NSP) with cellulose, xylose, pectin and lignin contents (Carre & Brillouet, 1986).…”

An experiment was conducted to determine the effect of enzyme supplementation to laying hens diets containing different levels of sunflower seed meal on performance and egg quality. The experiment was used 128 laying hens (Hy-Line W36) at 44 week of age throughout 84 days. Sixteen diets consisting of four levels of sunflower seed meal (0, 5, 10 and 20 % diet) and four levels enzyme (0, 500, 1000 and 2000 mg/ kg diet) in 4 x 4 factorial arrangement were used with four replicates of two birds each. During the experiment, feed and water were used as ad libitum. The effect of enzyme supplementation to laying hens diets containing different levels of sunflower seed meal did not significantly effect on egg production, egg weight, egg mass, feed intake, feed conversion ratio, egg shell weight, egg shell thickness and egg shell breaking strength (P>0.05). The result of this study that containing 20% sunflower seed meal to laying hens diets can be used without adversely affecting performance and egg quality.

“…Soybean meal is the main crude protein (CP) source that is used, as it contains adequately balanced amino acids and satisfactory essential fatty acids (FAs) to satisfy the laying-hen nutritional requirements (Hammershoj & Steenfeldt, 2005;Shi et al, 2012;de Morais Oliveira et al, 2016). The exceptional performance of soybean meal has increased its demand in the animal feed industry, which has subsequently led not only to its scarcity but also to an increase in its price (Laudadio et al, 2011;Abbas, 2013).…”

The objective of the study was to determine how the partial supplementation of Moringa oleifera whole seed meal (MOWSM) would affect layer performance, egg quality and egg fatty acid profile. One hundred and forty-four Hy-Line hens in early-lay (20-weeks-old), with an average body weight of 1.45 kg were randomly allocated to four dietary treatments which were formulated to meet or exceed the National Research Council standards for brown-egg laying hens. Dietary treatments consisted of 0 (control), 1, 3, and 5% MOWSM. Layer performance was monitored over a period of 8 weeks. The inclusion of MOWSM in layer diets reduced feed intake, bodyweight, the rate of lay, egg weight, and egg mass. Yolk colour was significantly improved by 1, 3 and 5% inclusion levels, while the albumen height decreased. The albumen weight, yolk weight, eggshell weight, eggshell thickness, and egg shape index showed no statistical differences across all treatment groups. Similarly, the saturated fatty acid profile was also not affected. Palmitoleic acid decreased with the increase in MOWSM inclusion, whilst linolelaidic acid increased. The atherogenicity index was not affected by MOWSM inclusion, while the thrombogenicity index increased when compared to the control diet. It was concluded that, although MOWSM inclusion improved yolk colour, maintained external egg quality, and improved the fatty acid profile, the deleterious effect that it had on layer performance indicated that it may not be fed to early-lay hens at these respective levels.
