The experimental feed consisted of ammoniated rice straw and concentrate (40:60) weighing 4% DM body weight. This study was subjected to a randomized complete block design (RCBD), analyzed six groups of initial weight of sheep allotted into three treatment groups: 0%, 1%, and 2% CRM of DM feed. The measured variables were energy intake (EI), digestible energy (DE), metabolizable energy (ME), energy retention (RE), and efficiency of RE to EI, RE to DE, and RE to ME. The results showed significant effects (P<0.01) of supplementing CRM in the feed on EI, DE, ME, RE, and efficiency of RE to EI, RE to DE, and RE to ME. The orthogonal polynomial test revealed that a higher dose of CRM supplementation in the feed has quadraterally increased (P<0.01) EI, DE, ME, and RE with peak points on 0,62%; 0,80%; 1,05%; 1,09%, respectively, and linearly increased (P<0.01) the efficiency of RE to EI, RE to DE, and RE to ME. It was concluded that the addition of CRM at the level of 2% was able to produce optimal energy efficiency in sheep.","PeriodicalId":31305,"journal":{"name":"Buletin Peternakan","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45970158","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}

This study aimed to evaluate the current increased price and fattening cost of feeder Brahman Cross (BX) cattle along with ESCAS additional cost on the price of slaughtered cattle and their welfare. Based on the results, the animal welfare assessment in the feedlot for 120 days were considered good, with the average value in the first month 86.40%, then in the second month 88.50%, in the third month 92.14%, and the fourth month 94.29%. Based on the calculations result of the Activity Based Costing (ABC) method in each supply chain, it is known that procurement costs, including the purchase of feeders, contributed to 94,0% of the total costs, while other costs were handling costs 2.70%, cost of ESCAS 1.56%, selling cost 1.52%, and the lowest, maintenance cost 0.24%. Therefore, to fatten Australian BX cattle, special strategies are needed, such as: optimizing stock in the feedlot; efficiency cost in feed ingredients without reducing quality; applying animal welfare rules to minimize handling costs and selecting vendors who want the lower price in providing ESCAS support facilities and establishing regular maintenance of the ESCAS supporting tools.","PeriodicalId":31305,"journal":{"name":"Buletin Peternakan","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45268000","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}

Three subdistricts (20%) with formal and informal farmers' groups were selected, and there were Taman, Pemalang, and Belik subdistricts. One Village was selected for each subdistrict. Respondents for informal groups were taken by census method. Respondents in formal groups were taken by random sampling, and the number of respondents followed the number of informal groups. There were 136 farmers selected as respondents. (69 from each formal and informal groups). The data were analyzed using the descriptive and rank Spearman correlation methods. The results showed that the farmers' commitment of formal group and informal group members was in the moderate and low categories respectively based on the percentage score interval scaling method. Resources accessibility of formal and informal members of the farmers' group was in the low to moderate category, but the member of formal groups was slightly better. There was a strong correlation between the accessibility of resources with the commitment in the formal groups, whereas in the informal groups there was a moderate to strong correlation between the accessibility of resources with the commitment of buffalo farmers. Based on the conclusion, this study recommend that the government should assist the informal farmer group to establish formal group with the result that would increase farmers accessibility toward information, support, and capital.
