“…Feng et al (2007) quantified the enzymatic activity (in units of substrate composed per milligram of dry matter from digestion) in the duodenum, jejunum and ileum and verified an increase of 52 % in the proteolytic activity of trypsin in the duodenum and jejunum, with a decrease of this compound within the lumen. Furthermore, this activity increases the height of the villus and the depth of the crypt in the three segments of the large intestine, resulting in greater capacity of digestion and absorption.…”

An outstanding feature of poultry production that provides animal protein yield for human feeding is its short production cycle. This characteristic has a linear relationship with waste production. Increasing the inclusion of this residue in diets in the near future is desirable in step with the growth of poultry production since it offers a better environmental and nutritional alternative to current methods. We evaluated the effects on the performance and carcass characteristics of broiler chickens produced by the inclusion of poultry offal meal (POM) in their feed. Treatments consisted of a control diet (corn, Zea mays and soybean, Glycine max) and four diets with inclusion of 30, 60, 90 and 120 g kg -1 of POM. The diets were formulated based on the level of digestible amino acid once categorized as isocalcic, isophosphoric, isosodic, isoenergetic and isonutritive for protein, methionine+cystine, lysine and threonine. The feed's electrolytes were corrected so that each diet had the same electrolytic balance. The variables analyzed were feed intake, weight gain, feed conversion ratio, body weight, carcass yield, chicken cut yield and abdominal fat.

“…Another hypothesis refers to the presence of protease inhibitors in the composition of soybean meal that, as reported by Feng et al (2007), correspond to almost 3 mg g -1 of soybean dry matter. The use of processing to avoid such undesirable components is unavoidable.…”

“…Many studies have reported the relationship between small-sized peptide ingestion and Ig concentration in blood. Wang et al (2003) demonstrated that adding 3 g of small peptides per kilogram BW to the basal diets of piglets increased the concentration of immunoglobulin, and Feng et al (2007) showed that fermented SBM having small-sized peptides increased the level of IgA and IgM, but not IgG, in broiler chickens. In chickens, IgG concentrations were greater in animals receiving mannan-oligosaccharide (MOS) compared with those of control animals (Savage et al, 1996).…”

The effects of hydrolyzed yeast supplementation on growth performance, health and immune-physiological parameters in neonatal calves challenged with vaccine were investigated. Twelve Holstein calves were started in the experiment at 2 6 1 days of age and were studied for 35 days. Calves were randomly assigned to each of two dietary treatments, a control (CON) and hydrolyzed yeast (HY) group. The calves in the HY group received control calf starter supplemented with 0.2% HY. All calves were given calf starter ad libitum for 5 weeks starting in week 1. Calves were also given whole milk according to a step-down milking protocol. In order to induce immune responses, all calves were challenged with Hog cholera and Erysipelothrix insidiossa live vaccines by intramuscular injection at 3 weeks of age. Growth performance and feed intake were not affected by dietary treatment throughout the experimental period, except that the HY group had significantly higher ( P , 0.05) milk intake than did the CON group at 3 weeks of age. Calves in the HY group showed significantly better ( P , 0.05) fecal and health scores at 3 weeks compared to those in the control group. After vaccine challenge, neutropenia, lymphophilia and thrombocytopenia were observed in the CON group, but calves in the HY group did not show significant changes of leukocytes. The average concentration of serum haptoglobin in the HY group was significantly higher ( P , 0.05) at 1 and 3 days post-vaccine challenge (DPVC) than that of CON group. Feeding HY supplemented calf starter resulted in a higher ( P , 0.05) relative amount of bacterial and viral -specific IgA than in the CON group at 5 DPVC. Although the percentage of CD4 1 T cells was significantly ( P , 0.05) higher in the HY group than in the CON group at 22 DPVC, significant differences between groups after vaccine challenge was not observed during the experimental period. These results suggest that 0.2% HY supplementation in calf starter can improve the health status and immune-related serum protein production and affect blood cell composition in neonatal calves after vaccine challenge.

“…Allergic factors cause hypersensitivity reactions, promoting a shortening of the intestinal villus and decreasing the ratio between the villi length and crypt depth (Thomaz et al, 2011). The presence of ANF in the diets of broilers from one to 21 days of age implies a reduction in feed intake, impaired digestion and utilization of nutrients (Feng et al, 2007;Kim et al, 2010).…”

Two experiments were carried out to evaluate the effect of using soy protein concentrate (SPC) in pre-starter and starter diets for broilers. In the first experiment, 600 male Cobb broilers, between one and 40 days of age, were distributed in a completely randomized design, with four treatments and six replications of 25 birds each. Treatments were ofered to broilers in the pre-starter and starter diets and consisted of inclusion of soy protein concentrate (0,3,6 and 9%) in diets. The parameters evaluated were: body weight gain, feed conversion ratio, consumption of ration, enzyme production in the pancreas, villus: crypt ratio, leukocyte count and immunoglobulin A (IgA) dosage. Aimed to determine the coefficient of nutrient metabolization of feeds, 144 male Cobb chicks were distributed, between 14 and 21 days of age, with four treatments and six replications of six birds per experimental unit. Treatments were the same as in the first experiment. The use of 3 and 9% of SPC did not affect weight gain, feed intake, feed conversion or viability of the poultry. The use of 6% of SPC provided an increase in trypsin activity, villi length and crypt depth; the coefficient of dry matter metabolization increased linearly; but no differences were observed in performance or immunological parameters.
