All pigs were randomly assigned to three groups based on the initial body weight (6.47 ± 0.45kg). There were eight replicate pens per treatment and five pigs (three barrows and two gilts) per pen. The DAG in the levels of 0%, 0.05%, or 0.10% was used as supplement to the corn–soybean meal-based basal diet. Piglets fed the diet supplemented with graded levels of DAG linearly increased the average daily gain (ADG) during days 22–42 (P = 0.027) and 1–42 (P = 0.048). In addition, a tendency in the linear reduction of fecal ammonia (P = 0.095), hydrogen sulfide (P = 0.078), and methyl mercaptan (P = 0.085) emission was observed by increasing the DAG levels in the diet. However, feeding pigs with DAG-containing diet had no significant effects on the nutrient digestibility and hematology parameters. Therefore, the suitable dose of DAG used in the diet of weaned piglets was at 0.10% to improve ADG and reduce fecal gas emission.","PeriodicalId":9512,"journal":{"name":"Canadian Journal of Animal Science","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2022-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42132573","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experimental diets, including the control (C), C + E, and C + E + Y, were fed to seven replicate pens of four birds from 22 to 56days of age. The addition of E + Y resulted in a significant decrease in the relative abundance of Firmicutes and a significant increase of Actinobacteria in ileal digesta. A significant decrease in the abundance of Firmicutes was not followed by the abundance of Ruminococcaceae, one of the butyrate-producing bacteria. This coincided with a significantly increased concentration of butyrate in the ileal digesta and the proportion of butyrate within the total short-chain fatty acids (SCFA). As opposed to the ileum, the addition of E or E + Y did not affect the relative abundance of Firmicutes in ceca. The higher content of SCFA in the cecal digesta than in the ileum would reflect differences in microbial activities in both compartments, and possible increased SCFA absorption from the ileum. Overall, the positive effects of enzyme and yeast bioactive supplements on bacterial communities appeared to be more pronounced in the small intestine.","PeriodicalId":9512,"journal":{"name":"Canadian Journal of Animal Science","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2022-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41655954","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All ingredients were ground into fine or coarse products and then pelleted at one of three different temperatures. Grinding reduced the total starch (TS) content of Amarillo peas and chickpeas (P < 0.05), crude fibre (CF) in Dun peas (P < 0.05), and total dietary fibre (TDF) and insoluble fibre (IDF) in lentils (P < 0.05). Grinding only affected soluble fibre (SDF) in chickpeas. The effect of pelleting was variable for TDF across pulses. Pelleting did not affect the SDF content of pulses (P > 0.05). Finely processed SBM had higher (P < 0.05) TS, TDF, and IDF content than coarsely processed SBM.

Increasing drug resistance and variable vaccine effectiveness have stimulated interests in developing alternate control strategies. Our research studied the effects of dietary supplementation of multienzyme (phytase, xylanase, β-glucanase, amylase, hemicellulase, and pectinase) in broiler chickens infected with coccidial pathogens by assessing (i) nutrient utilization, immunological response, and gut health-related indicators in small intestine; and (ii) intestinal microbiome modulations. One-day-old male Ross 708 chicks were assigned to 4 treatments in a 2 × 2 factorial arrangement comprising of 0 or 50 g·kg−1 multienzyme and oral challenge with phosphate buffer saline or mixed Eimeria spp. oocysts (250000 E. acervulina, 50000 E. maxima, and 50000 E. tenella). Multienzyme reduced (P < 0.05) Eimeria-induced loss in feed efficiency and nutrient utilization, partially explained by reduced decrease of b0,+ amino acid transporter in jejunum. Multienzyme suppressed (P < 0.05) the overexpression of interleukin-8 in duodenum and jejunum and ameliorated (P = 0.05) the decreased expression of antioxidant heme oxygenase 1 in ileum induced by Eimeria infection. Multienzyme facilitated (P < 0.01) the bloom of short-chain fatty acid-producing and fiber-degrading microbes. Multienzyme supplementation partly mitigated the adverse effects of Eimeria infection through multiple mechanisms: improving nutrient utilization, reducing local inflammation, and restoring microbial homeostasis.","PeriodicalId":9512,"journal":{"name":"Canadian Journal of Animal Science","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2022-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47672424","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Extrusion is one technique utilized to process pulses and is reported to increase starch and protein digestibility but also has the potential to transform nutrients into non-nutritious compounds. This study sought to compare the effects of extrusion on nutrient composition in Amarillo peas, Dun peas, lentils, chickpeas, and faba beans, with soybean meal (control). Each pulse was extruded at 18% or 22% moisture and 110, 130, or 150 °C. Compared to whole samples, extrusion increased crude protein content of Amarillo and Dun peas, and lentils, and it decreased in soybean meal (P < 0.05). Compared with whole samples, extrusion increased methionine content in chickpeas and lentils (P < 0.05), with no effect in Amarillo or Dun peas, faba beans, and soybean meal. Cysteine content increased in extruded Amarillo peas compared with whole pulses, and decreased in soybean meal (P < 0.05). Results suggest that extrusion can positively affect protein and amino acid content of pulses, however, specific changes differ by pulse/legume type.","PeriodicalId":9512,"journal":{"name":"Canadian Journal of Animal Science","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2022-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47239985","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
