A total of 240 male Ross 308 broiler chickens aged 14 days were individually weighed and randomly allocated to four experimental treatments by using a completely randomized design (CRD). Each treatment consisted of 6 replicates and 10 birds per replicate. From days 15 to 42, chickens were provided four experimental diets: treatment 1 (T1)5% fish meal based diet as control, treatment 2 (T2)5% feather meal based diet, treatment 3 (T3)5% meat and bone meal based diet, and treatment 4 (T4)5% blood meal based diet. Broiler feed intake, weight gain and feed conversion ratio (FCR) were measured and calculated on weekly basis. On weekly performance basis, feed intake of broilers did not differ significantly (p>0.05) among all treatments on 4 th and 5 th weeks, and the weight gain of broilers fed different dietary treatments were not significant differences (p>0.05) on 5 th and 6 th weeks. Other results based on weekly and cumulative performance showed T1 was highest feed intake, weight gain, final body weight and FCR among the treatments, then T3 was higher performance than T2 and T4. The treatment 4 was the poorest cumulative FCR among all different dietary treatments. It can be concluded that broiler fed diet with 5% fishmeal is the most beneficial, and 5% blood meal is the poorest performance among the treatments.","PeriodicalId":351246,"journal":{"name":"Journal of Livestock Science","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122008381","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}

From chickens at one day of age, according to the principle of analog groups, we formed 4 groups of 200 heads each. It was found that broiler chickens 3 experienced were distinguished by the best slaughter characteristics due to the high detoxification effect with joint additions to the composition of diets with an excess content of HM salts of probiotic, vitamin E and sodium selenite. Moreover, in the meat poultry of this group during the present experiment, compared with the analogs of the control group, higher indicators of the mass of a half-gutted carcass were observed by 11.93%, gutted – by 12.23%, slaughter yield – by 1.11%. With the combined use of a probiotic and two antioxidants in the compound feed formulation, samples of white meat from broilers of the 3rd experimental group were distinguished by the best nutritional properties, in which, relative to analogs from the control group, in the samples of pectoral muscles, the dry matter concentration increased by 1.12%, protein – by 1.14% while reducing the level of fat – by 0.40%. It was found that due to the efficiency of detoxification of toxicants during joint feeding of tested drugs against poultry of the control group in broilers of the 3rd experimental group in samples of pectoral muscle (white meat) there was an increase in the concentration of the amino acid tryptophan by 0.11%, which provided significant increase in the value of meat PQI – by 15.96%. Due to this, the poultry of this group in the pectoral muscle samples contained less zinc – 2.71 times, cadmium – 2.57 and lead – 2.65 times.","PeriodicalId":351246,"journal":{"name":"Journal of Livestock Science","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125102800","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}
