The experiment was executed in Aberegelle Agricultural Research Centre goat farm in the northern Ethiopia. Four treatments namely grass hay (GH) as a control, air dried acacia saligna leaves (ADASL), water soaked acacia saligna leaves (WSASL) and wood ash soaked acacia saligna leaves (WASASL) each included at 300 g head -1 day -1 were used as supplement. Feed intake was measured daily and live weight gain recorded weekly. Measurements were also taken on empty body weight (EBW), hot carcass weight (HCW), dressing percent (DP) and rib eye muscle area (REMA). Higher total crude protein intake was observed in the supplemented goats as compared to non-supplemented. As a result, better body weight gain was observed in the supplemented goats as compare to non-supplemented goats. Similarly, better HCW was obtained in the supplemented goats than non- supplemented in general and in particular goats fed on air dried and water soaked leaves showed significantly higher HCW than the control. So that it could be included that, it is important to feed acacia saligna leaves as an alternative feed particularly at the time of feed scarcity. However, dressing percent on slaughter weight base (SWB), EBW base and REMA were not showed any significant different (P>0.05) among the treatments. Generally, goats supplemented with air dried leaves showed higher body weight gain and carcass value compared with the other treatments.","PeriodicalId":210831,"journal":{"name":"Scientific Journal of Animal Science","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116865741","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}

Twenty four male Atabay lambs were in a completely randomize design (CRD) with 4 treatments and 6 replications. Gaded levels of canola meal (0, 33, 66 and 100 percent) were used instead of cottonseed meal. Lambs were weighed, and feed consumption was recorded for feed efficiency ratio computation in every month and whole of the experimental period. Finally carcass analysis was carried out for every treatment. The canola meal used in this experiment contained 14.75 µmole/g DM aromatic glucosinolates. The results obtained showed that the effects of different levels of canola meal on daily gain during the whole experimental period was not significant (p>0.01), significant difference (p 0.01). Carcass characteristics, except for liver weight, were not statistically different (p>0.01). Effect of different levels of canola meal on thyroid hormones secretion was not statistically significant (P>0.01). Therefore, it is recommended that canola meal can be used in the diets of Atabay finishing lamb without any problem.","PeriodicalId":210831,"journal":{"name":"Scientific Journal of Animal Science","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124562645","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}

However, in many animals and in case of fish is unknown how Intestinal microbiota is formed, which species are dominant and which one has capacity probiotic for use in aquaculture. The goal of this study was to establish the bacterial load that dominates the back intestine of Carassius auratus. A batch of 200 healthyjuvenilefishes were obtained from an ornamental fish farm in Mexico City. The fish were maintained in two culture beakers of 100 L during 15 day to acclimatization to ensure any sign of injury disease. To extract the back of gastrointestinal tract, which was rinse several times with distilled water for food and feces residues elimination. The sample was inoculated in 9 mL of sterile saline solution and from this, three dilutions in a 1:10 relation were made, inoculating 0.1 mL from each dilution in agar plates MRS, BHI and TCBS, and were incubated at 27oC for 24 hours. Subsequently a colony forming units (CFU mL-1) count was made, with the help of a Quebec counter type. Colonies were purified through successive inoculations. The molecular identification was made out by sequencing the gene RNAr 16S using Wizard Genomic. Molecular identification showed that the back region of the intestinal tract of C. auratus was dominated by phylum Proteobacteria and Firmicutes represented by the genus Bacillus , Vibrio , Vagococcus , Brevibacillus , Aeromonas , Pseudomonas , Shewanella , Enterococcus , Paenibacillus and Morganella. In relation to bacterial abundance by specie it was established that Bacillus sp. and Pseudomonas stutzeri were the most abundant reaching CFU mL -1 counts of 210 and 167 respectively, followed by Paenibacillus lactis with 103 CFU mL -1 and Bacillus cereus with 100 CFU mL -1 while Enterococcus eurekensis was the least abundant with an average value of 6 CFU mL -1 .","PeriodicalId":210831,"journal":{"name":"Scientific Journal of Animal Science","volume":"58 21","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120886550","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}
