This study was designed to assess the in vitro antibiotic activity of the water and ethanolic extract of bitter leaf against Salmonella sp, Shigella sp, Staphylococcus sp, Escherichia coli and Pseudomonas aeruginosa. Antimicrobial susceptibility test was done using Kirby-Bauer disc diffusion method. Results obtained showed that none of the organism tested was sensitive at 20% of the water extract. Sensitivity increased from 40% to 100% of the water extract. The highest zone of inhibition (ZOI) of 17.00±1.00 mm was obtained for Staphylococcus sp, followed by 16.33±1.15 mm for P. aeruginosa both at 100%. The highest ZOI for the ethanolic extract of bitter leaf (27.67±2.52 mm) was recorded for Staphylococcus sp followed by 25.00±2.00 mm for E. coli both at ethanol extract concentration of 300g /ml. We therefore conclude that bitter leaf can be considered as potential alternative to synthetic antibiotic growth promoters in poultry.","PeriodicalId":13503,"journal":{"name":"Indian journal of animal nutrition","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82077560","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}

The concentrate mixtures contained an average of 22.1% crude protein (CP). The range of values obtained for various CNCPS protein fractions (% CP) was: 6.9-8.9, 12.7-24.1, 46.3-55.1, 15.3-17.6, 5.4-11.1 for A, B 1 , B 2 , B 3 and C, respectively across various treatments. Furthermore, rumen undegradable protein was maximum (P<0.01) at 100% MGM inclusion, whilst it was minimum (P<0.01) with GNC-based control. However, intestinal protein digestibility did not differ across treatments. The gas volume (GV) was highest (P<0.01) in control and lowest (P<0.01) in 100% MGM inclusion. Both in vitro dry matter and organic matter digestibility were greatest (P<0.01) at 100% MGM and lowest (P<0.01) at 100% RGM level. Methane, expressed as ml/g was maximum (P<0.01) in control and minimum (P<0.01) at 100% MGM inclusion. In addition, partitioning factor, microbial biomass production (MBP) and MBP: GV were maximum (P<0.01) for 100% MGM and minimum (P<0.01) for the control group. While pH of rumen fluid did not vary, ammonia nitrogen and total volatile fatty acids were found maximum (P<0.01) in control and minimum (P<0.01) at 100% MGM. Moreover, the molar percentage of acetic acid was highest (P<0.01) at 100% MGM but lowest (P<0.01) with 100% RGM diet, whereas the opposite results were true for propionate and butyric acid.

Betaine, a trimethyl derivative of glycine is a normal metabolite in many plant and animal tissues. In all the animals, betaine is produced by oxidation of choline or supplied through feed. Its characteristics chemical structure makes betaine a dipolar zwitterion, conferring it osmoprotective and methyl donating properties. Over the past decades, numerous studies have investigated and published the favorable effects of betaine on performance in different animal species. Betaine is involved in transmethylation reactions for the synthesis of several metabolically active substances like creatine, carnitine etc. Also, it has shown evidence to increasing nutrient utilization, digestibility and methionine availability. Boosting immune status and reducing oxidative or heat stress are also some of the important functions of betaine. Most of the researches have specifically studied the growth promoting, carcass modulating, immune boosting or stress reducing properties of betaine in different species. Literature covering on different benefits of betaine as an essential feed supplement is not yet abundant. As both poultry and pig are important species of domesticated animals, betaine can be a better and cheaper, alternative feed supplement for enhancing the nutrient utilization and performance of poultry and pig. Therefore, an attempts have been made to delineate the functional effects of supplementary betaine in poultry and pig.","PeriodicalId":13503,"journal":{"name":"Indian journal of animal nutrition","volume":"41 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72606676","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}

A total of 250 day-old male broiler chicks were randomly divided into five treatment groups with ten replicates of five birds each.

However, feed intake was not affected by different herbal supplementation at 42 d of age. The Lipid peroxidation, alkaline phosphatase, blood urea nitrogen, serum cholesterol, blood glucose levels and E. coli counts in small intestine were significantly (P<0.05) lower in herbal supplemented groups compared to control and was at par with vitamin E and Se supplemented group.
