These alternatives modulate the gut microbiota and enhance animal production performance. This study aimed to assess the impact of Allium sativum on the production performance of broiler chickens.\u0000Materials and methods: A total of 280 day-old broiler chicks were examined for 42 days. After being sexed, they were randomly allocated into five groups, each consisting of 14 chicks, with four replications. The control group was fed on a ration without additives (R0-). The treatment groups consisted of a control diet supplemented with 1 g of antibiotic Doxycycline® per kg of basal diet and per liter of drinking water (R0+) and 5 g garlic per kg of basal feed and also per liter of drinking water (RAs), respectively. To facilitate the oral administration, the solution was absorbed by charcoal from the fruit stones of Canarium schweinfurthii at a rate of 100 g and 100 ml per kg of diet and per liter of drinking water, respectively. The investigated parameters included growth performance, microbial flora, markers of kidney, and liver function, and feed digestibility.\u0000Results: The results revealed Allium sativum significantly decreased feed intake, feed conversion ratio, serum aspartate aminotransferase, alanine aminotransferase, and urea levels regardless of the administration mode in broiler chickens, compared to the negative control. When administered through both feed and drinking water, garlic significantly increased live weight, weight gain, and lactic acid bacteria count, compared to the negative control. Feeding garlic to broilers had insignificantly affected the digestibility of feed components irrespective of the administration mode.\u0000Conclusion: In conclusion, Allium sativum can effectively serve as a feed additive in broiler diets or drinking water, promoting growth performance without harming kidney and liver functions. The present findings help address concerns about antibiotic resistance and residues in poultry products.","PeriodicalId":502736,"journal":{"name":"Journal of World’s Poultry Science","volume":" 50","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140384328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Performance of Broiler Chickens Fed Different Cereal Based Diets Supplemented with Saccharomyces cerevisiae","authors":"Timothy Kuka, O. Adeleye, Abideen Adetona","doi":"10.58803/jwps.v3i1.23","DOIUrl":"https://doi.org/10.58803/jwps.v3i1.23","url":null,"abstract":"Introduction: Inefficient poultry production has been a serious challenge due to poor performance and scarcity of feed resources, which necessitate the exploration of alternatives. This study was conducted to assess the effect of Saccharomyces cerevisiae (SC) as a supplemental protein and growth promoter in different cereal-based diets on growth performance, serum biochemistry, characteristics of digesta, and nutrient digestibility of broiler chickens.\u0000Materials and methods: A total of 324 day-old broiler chickens, comprising of mix sexes with an average weight of 45.36 ± 0.73, were randomly assigned to nine treatments, each consisting of three replicates with 12 birds per replicate. Three diets were formulated, each incorporating maize, sorghum, and wheat. The diets varied in the SC inclusion at levels of 0%, 5%, and 0.2% oxytetracycline (used as a growth promoter). The inclusion of oxytetracycline was to simulate the practice of in-feed antibiotics growth promoter, whereas yeast served as supplemental protein and growth promoter. Titanium dioxide was included in the feed at 0.2% on day 21 of the experiment to help estimate nutrient digestibility.  \u0000Results: Weight gain and feed conversion ratio were significantly lower in the groups fed sorghum with and without yeast. The groups fed maize with SC and oxytetracycline had the lowest blood glucose. Maize and sorghum without SC had the highest pH values. Protein digestibility was the lowest in the group fed sorghum with SC and wheat without SC.\u0000Conclusion: Individual cereal diets performed competitively, supplementation of SC in different cereal-based diets did not influence their contribution and performance of the chickens. The inclusion of 5% SC reduced protein digestibility. Oxytetracycline yeast as a supplemental protein and growth promoter did not improve the performance of the chicks.","PeriodicalId":502736,"journal":{"name":"Journal of World’s Poultry Science","volume":" 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140382038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
