“…Although the prices of corn, wheat, and other cereals have been stabilized by increased production of these foods, costs remain high. Therefore, research has focused on developing new alternative feed stuffs with a higher productive efficiency while maintaining good quality (Olmo, Martínez, León, & Leyva, 2012;Roberts et al, 2015).…”

This study is aimed at determining the effects of dietary enzymolysis products of wheat gluten on the growth performance, organ weights, serum and intestinal antioxidant indices, serum biochemical indicators, and immunoglobulins of broiler chickens. The treatments consisted of a basal control diet, 2% of wheat gluten, and 1%, 2%, 3%, and 4% of enzymolysis products of wheat gluten. The inclusion of up to 4% of enzymolysis products of wheat gluten improved body weight and average daily gain. At 21 days, serum superoxide dismutase (T-SOD) had increased in the 2% of wheat gluten treatment (P < .05). At 42 days, both serum T-SOD and blood urea nitrogen had increased while uric acid had decreased (P < .05) in 2% enzymolysis products of wheat gluten treatment. These results showed that dietary inclusion of 2% enzymolysis products of wheat gluten can have beneficial effects on the growth performance and intestinal antioxidant activities of broiler chickens.

“…Currently, its contribution to national GDP is 1.3%, whereas its contribution to the agriculture sector, total meat production and in the whole GDP is 5.76%, 26.8% and 1.26%, respectively (Hussain et al, 2015). Better intestinal health and high digestibility of nutrients in broilers are extremely important in order to attain higher body weight and better FCR (Roberts et al, 2015). Maintenance of gut development and health is very important to support development and health of the bird (Choct, 2009).…”

The effect of microencapsulated butyric acid (MEBA) on growth performance, ileal digestibility (ID) of protein, gut health and immunity was assessed in broilers. A total of 336 d-old Hubbard Classic broilers chicks were randomly assigned to four dietary treatments (Control, 0.25, 0.35 and 0.45 g/kg of MEBA). Each treatment was replicated three times with 28 birds/replicate. Feed intake, body weight gain, FCR, intestinal morphology, ID of protein and immunity was evaluated. At 35-d of age, three birds/replicate were randomly selected and slaughtered to collect blood, duodenal samples, and ileal digesta. The Improved body weight gain (P = 0.05), FCR (P<0.01), duodenal villous height (P<0.05) and ID (P<0.1) were observed; whereas, unresponsive treatment effect with respect to feed intake (P>0.5) and antibody titer against Newcastle disease (P>0.05) were noted. The results indicated that MEBA improves digestion and absorptive processes which consequently improved the broilers performance.

“…Such investigations are important because the gastrointestinal tract is the primary surface of contact with digesta (Koutsos & Arias, 2006). Its physiological state will determine the digestive and absorptive capacity of the intestine, and consequently growth performance of broilers (Roberts et al, 2005;Haoyu, Ivarsson, Lundh, & Lindberg, 2013). Thus, it is important to investigate the effect of the leaf meal on the digestive and absorptive properties of intestines.…”

The effect of A. angustissima leaf meal based diets on intestinal physiology and dressed carcass weight was investigated on 150 day old chicks. Three diets, 0, 5 and 10% A. angustissima were used in a three phase feeding programme. At days 14, 28 and 42, two birds from each replicate were slaughtered, dressed and weighed. The weights and lengths of the duodenum, jejunum and colon were measured. Approximately 1 cm specimen was taken from each organ, fixed in formalin and stained for histological analysis. Using a light microscopy, the digestive and absorptive properties of the tissues were assessed. Inclusion of A. angustissima leaf meal increased intestinal wall thickness, epithelial thickness, and villus height of the duodenum (P < 0.05). There was no effect on the proportional weight and length of the jejunum, jejunum villi height and villi width (P > 0.05) but jejunum wall thickness decreased with increasing levels of the leaf meal (P < 0.05). Leaf meal inclusion resulted in an increase in weight, intestinal wall and mucosal thickness of the colon (P < 0.05) and a decline in sub-mucosal fold height and haustra coli width of the colon (P < 0.05). Dressed weight was the same across diets at two weeks (P > 0.05). At four and six weeks, broilers on the control and 5% diet had superior dressed weights to the 10% fed broilers (P < 0.05). It was concluded that for intestinal physiological adaptation that will not compromise weight gain in broilers, up to 5% A. angustissima could be included in broiler diets.
