The aim of this study was to evaluate the effects of glutamine and threonine supplementation on the ileal mucosa of broilers aged 21-42 days. Six-hundred and forty-one-day old chicks of the Cobb Slow lineage were utilized in this study. From 1 to 21 days of age, the chicks received a commercial diet; and after 22 days, the broilers were distributed in a completely randomized design in a 2 ? 4 factorial scheme (challenge and diet), with 4 replications and 20 chicks per experimental unit. At 22 days of age, the challenged broilers received a commercial vaccine against coccidiosis. A commercial diet was utilized as control and three other diets were formulated with reduced crude protein (-3%), and were corrected with the addition of glutamine (Gln) and glutamic acid (Glu) as non-specific nitrogen sources, and finally supplemented with L-Threonine (Thr) at 0.70, 0.80, and 0.85% digestible threonine, respectively. At 28 days of age, diets with Gln/Glu + Thr resulted in greater ileal villi lengths. Challenge with Eimeria sp. reduced the number of goblet cells and increased the duodenal and jejunal crypt depths. At 42 days of age, an interaction was observed between diet and challenge in relation to ileal villi length; better results were observed in the challenged broilers that received 0.85% Gln/Glu + Thr. The mucosal morphology in the ileal villi extremities was preserved in the challenged broilers that received higher Thr levels in their diets. The results suggested that the inclusion of glutamine and threonine affected the morphometry and mucosa of the ileum, thereby improving the mucosal quality.

The objective of this study was to evaluate the effect of adding different xylanase and ?-glucanase enzyme blends to maize- and soybean meal-based diets on performance and energy metabolizability in broilers. Two experiments were carried out with broilers of the COBB 500 strain. In the first experiment, 1960 chicks were assigned to a completely randomized design with a 2 × 3 + 1 factorial arrangement, totaling seven treatments, namely, T1- Positive control (PC); T2 - Negative control 1 (NC1; PC minus 200 kcal kg-1 ME); T3 - NC1 + Blend A; T4 - NC1 + Blend B; T5 - Negative control 2 (NC2; PC minus 167 kcal kg-1 ME and 5% amino acids); T6 - NC2 + Blend A; and T7 - NC2 + Blend B. Fourteen replicates were used per treatment and 20 birds per experimental unit. The parameters evaluated at 21 and 42 days of age were weight gain (WG), feed intake (FI) and feed conversion (FC). At 42 days, production efficiency index (PEI), viability and the yields of cuts were also calculated. Birds that received diets with a reduced nutritional value showed a reduction in WG and PEI and worsened FC as compared those of PC treatment (p < 0.05). However, the birds that consumed the NC2 diet with Blend B exhibited a similar WG to those in PC group (p > 0.05) from 1 to 21 days of life. For the yield of thigh + drumstick, the factors were statistically similar (p > 0.05) to those observed in the PC birds. In the second experiment, 432 fourteen-day-old chicks were distributed in a completely randomized design with seven treatments, with eight replicates per treatment and six birds per experimental unit. The apparent metabolizable energy (AME) and nitrogen-corrected AME (AMEn) values were determined. Overall, the NC2 diet with Blend B provided the highest AME and AMEn values; however, NC1 with the same enzyme blend was the treatment which provided the lowest values. The addition of xylanase and ?-glucanase enzyme blends to maize- and soybean meal-based diets improves WG at 21 days as well as PEI in broilers; however, it does not influence the yield of cuts. Enzymes (Blend B) improve the energy metabolization of broiler diets with reduced energy and amino acid levels.

Abstract The objective was to investigate the effects of a high canola meal-containing diet and multi-carbohydrase supplementation on growth performance and intestinal pH, short-chain fatty acid (SCFA) profile, and microbiome in weaned piglets. Twenty-four piglets (7.46 ± 0.23 kg BW) were individually assigned to 1 of 3 diets in a completely randomized design. Diets were fed for 21 d: SB, corn and soybean meal-based diet; CM, 25% canola meal substituting soybean meal and adjusted to meet energy and nutrient requirements of piglets (NRC, 2012); and CM+E, CM supplemented with multi-carbohydrase (0.01%). Feed disappearance and BW were recorded weekly. On d 21, piglets were euthanized to assess digesta pH, SCFA profile, and gut microbiome. Data were analyzed using the MIXED procedure of SAS using the piglet as the experimental unit. There were no differences (P &gt; 0.10) in growth performance and digesta pH. Piglets fed CM+E tended to (P = 0.051) or had significantly lower (P &lt; 0.05) butyric acid in the cecum than piglets fed CM and SB, respectively. Piglets fed SB had higher (P &lt; 0.05) isobutyric acid in the colon than piglets fed CM+E. Piglets fed SB and CM tended to have higher (P &lt; 0.05) isovaleric acid in the colon than piglets fed CM+E. Piglets fed SB tended to have lower (P &lt; 0.10) proportion of Bifidobacteria, and had lower (P &lt; 0.05) Enterobacteriaceae, Enterococcus, and Lactobacillus than piglets fed CM. Piglets fed CM+E tended to have lower (P &lt; 0.10) Bifidobacteria and higher Clostridium XIVa than piglets fed CM, and had lower (P &lt; 0.05) Enterococcus, but higher (P &lt; 0.05) Lactobacillus than piglets fed CM. In conclusion, feeding 25% of canola meal in substitution to soybean meal with or without multi-carbohydrase supplementation changed the intestinal environment by modifying SCFA profile and relative proportion of microbiome, but without affecting digesta pH or growth performance in nursery piglets.

The objective of this study was to evaluate the use of a vegetal source of choline as a replacement of choline chloride in the diet for broilers from one to 21 and 22 to 42 days of age. In the first experiment, we used 1500 Cobb male broilers at one day of age, distributed in a completely randomized design with ten treatments, five repetitions and 30 birds per experimental unit. In the second experiment, we used 1000 Cobb male broiler at 22 days of age, distributed in a completely randomized design with ten treatments, five repetitions and 20 birds per experimental unit. The treatments consisted of five levels of choline chloride 60% (400, 500, 600, 700 and 800 mg kg-1) and five levels of vegetal source of choline (100, 150, 200, 250 and 300 mg kg-1). There was no difference between the performance parameters of broilers in the periods of one to 21 and 22 to 42 days of age. The use of up to 100 mg kg-1 of a vegetal source of choline can replace the use of choline chloride, in the studied levels, in corn-soybean meal diets for broilers from one to 21 and 22 to 42 days of age.

Abstract Piglets experience a decline in body temperature immediately after birth, and both drying and warming piglets at birth reduces this. However, these interventions may have less effective at higher farrowing room temperatures. This study was carried out at a commercial facility to compare the effect of drying and/or warming piglets at birth on postnatal rectal temperature (RT) under relatively warm farrowing room temperatures (26.6 ± 2.09°C). Forty-five sows/litters were used in a completely randomized design to compare three Intervention Treatments (applied at birth): Control (no treatment); Warming (piglets placed in a plastic box under a heat lamp for 30 min); Drying+Warming (piglets dried with desiccant and warmed as above). Temperatures in the warming boxes over the study period averaged 37.7 ± 2.75°C. At birth, piglets were weighed; RT temperature was measured at 0, 10, 20, 30, 45, 60, 120, and 1440 min after birth. Blood samples were collected at 24 h after birth from a subsample of one piglet from each birth weight quartile within each litter to measure plasma immunocrit concentration. Data were analyzed using PROC MIXED of SAS with litter as the experimental unit; and piglet a subsample of litter. The model for analysis of piglet rectal temperature included fixed effects of treatment, measurement time (repeated measure), the interaction, and the random effect of sow. Compared to the Control, piglet RT were higher (P ≤ 0.05) for the Warming treatment between 10 and 60 min, and higher (P ≤ 0.05) for the Drying+Warming treatment between 10 and 120 min after birth. Rectal temperatures were higher (P ≤ 0.05) for the Drying+Warming than the Warming treatment between 20 and 120 min. Responses to drying and/or warming were greater for low birth weight piglets (&lt; 1.0 kg) than heavier littermates, but were generally less than observed in previous experiments with similar treatments carried out under cooler temperatures. Piglet immunocrit values were lower (P ≤ 0.05) for the Drying+Warming treatment compared to the other treatments, which were similar (P &gt; 0.05). Immunocrit values tended (P = 0.10) to be lower for light (&lt; 1.0 kg) compared to heavier birth weight piglets. In conclusion, drying and warming piglets at birth was more effective for reducing piglet RT decline after birth than warming alone, though the effect was less than observed in previous studies carried out under cooler farrowing room temperatures.

 This study aimed to evaluate the increasing levels (0, 1, 2, 3 e 4%) of fish by-product meal in diets for laying hens on performance, egg quality and economic analysis. A total of 160 Dekalb White hens with 52-wk old were distributed in a completely randomized design with five treatments and four replicates of eight birds each. The experiment lasted 84 days divided into four periods of 21 days. Estimates of fish by-product meal levels were determined by polynomial regression. Differences (p < 0.05) were detected for all variables of performance, in egg weight, yolk and albumen percentage, yolk and albumen height, feed cost and production cost, in which the inclusion of fish by-product meal in the diets showed better results. It can be concluded that fish by-product meal can be used in diets for hens as alternative feed, with better results in egg production, feed conversion, egg weight, yolk-albumen ratio and a reduction in feed cost and production cost.
