“…In contrast, Gilbert et al (2000a) claimed that although white lupine enlarged intestinal villi in chickens, the addition of enzymes (xylanase and cellulase) reduced their size. Our findings are in agreement with the results of researchers (Mathlouthi et al 2002;Gracia et al 2003;Mathivanan et al 2006), who applied enzymes targeting NSP to various diets for chickens, but without lupine.…”

This work examined the impact of enzyme preparation with specific activity towards non starch polysaccharides on performance, morphological characteristics of gastrointestinal tract organs, microscopic evaluation of jejunal mucosa, and microbial status of ileum, caeca, and excreta in broilers fed a diet containing a high content of lupine meal. One-day-old chickens (Ross 308, mixed sex) were randomly divided into control and experimental groups. Each group consisted of 36 birds, with 6 replications,and with 6 chickens per replication. The control group was fed the basal diet (consisting of maize and 40% of lupine), while the experimental treatment group was fed the basal diet supplemented with 0.06% commercial enzyme (Ronozyme VP). Chickens were fed diets in mash form for 4 weeks. Enzyme preparation significantly (P < 0.05) improved feed consumption and chicken growth, and slightly improved total tract digestibility of dietary ingredients and energy. Enzyme preparation significantly reduced (P < 0.05) the size of gastrointestinal tract organs and had an impact on jejunal mucous membrane of chickens evidenced by elongation of villi and deepening of crypts. No significant effects of dietary enzyme on counts of the analysed bacteria in the jejunal digesta were observed, but enzyme preparation significantly (P < 0.05) reduced the number of Enterobacteriaceae in caeca and excreta, and coliforms in excreta only (P < 0.01). Appropriate combination of enzyme preparations with activity towards degrading carbohydrates may offer a potential to reduce the deleterious impact of lupine in broilers.

“…Nevertheless, many feedstuffs having high fiber content have been commonly included in poultry diet, especially in extensive poultry production systems. However, depending on the solubility levels and concentrations, fiber in diets influences poultry performance [54][55][56].…”

Abstract:The present review discusses the existing research findings on the nutritional impact of forages in poultry diet and the significance of forages in sustainable poultry production systems. The nutritional composition and antinutritional factors of the main forages and the pros and cons of feeding forage on poultry meat and egg quality under free-range and organic production systems are also discussed. This review highlights the importance of forages and forage meals in poultry ration, considering that these feedstuffs may have greater value to the success of local poultry production in many regions of the world due to their potential of production.

“…In addition, broilers fed diets with high amounts of dietary fibre had lower abdominal fat (Shahin & Abdelazim, 2005). In the presence of dietary fibre, the secretion of bile acids and hepatic-intestinal circulation was reduced (Mathlouthi et al, 2002) which restricted lipids emulsification. These events result in decreased lipids absorption and lead to lower abdominal fat contents (Shahin & Abdelazim, 2005).…”

, 2015. Broiler chicken performance in response to various levels of raw and autoclaved rice bran. Bulg. J. Vet. Med., 18, No 4,[348][349][350][351][352][353][354][355][356][357][358][359][360] The inclusion of raw or autoclaved rice bran (RB) into broiler chicken diets was evaluated. A total of 420 broiler chickens (Ross 308) were assigned to a basal diet (without RB) or diets containing 6, 12, and 18% raw or autoclaved RB with 3 replicates of 20 chickens. By polynomial orthogonal contrasts, a significant reduction in body weight gain and feed intake (L: P =0.048), the weight of abdominal fat (L: P=0.048), ether extract digestibility (L: P=0.025), villus height (L: P=0.046), and crypt depth (L and Q: P=0.043) was achieved by increasing the inclusion levels of raw or autoclaved RB in the diets. On day 42, significant decreases were found in the weights and the ash contents of tibia (L: P=0.003) with increasing the level of raw RB in the diets. Decreased serum cholesterol was obtained following the inclusion of increasing levels of raw RB (Q: P=0.015) or autoclaved RB (L and Q: P=0.015) in the diets. The inclusion of RB in the diets resulted in poorer nutrient digestibility and performance, although it had some modulation effects on blood lipid biochemistry. It is suggested that the inclusion of raw RB in the diets should be limited to 6%, however, autoclaving allowed inclusion of RB up to 12% in the broiler diets.
