This study investigated the polymorphisms and expression of the HSD17β13 gene in lamb quality traits in Indonesian sheep. A total of 200 of rams of seven breeds administered in the study were Javanese fattailed (JFT), Javanese thin-tailed (JTT), Garut sheep (GS), Jonggol sheep (JS), Garut composite sheep (GCS), Compass agrinac sheep (CAS), Barbados cross sheep (BCS) aged 10-12 months and weighed 20-30 kg. The Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) and MspI enzyme restriction were performed to identify the polymorphism of the HSD17β13 gene. The lamb quality traits were measured for physical quality, flavor, odor, and fatty acid composition. The results showed that the HSD17β13 gene was polymorphic and had three genotypes i.e., CC, CT, and TT. The highest genotype frequency was the CC when compared to the other genotypes. The allele frequency of HSD17β13 gene was not in Hardy Weinberg Equilibrium. The polymorphism of HSD17β13 gene was significantly (P<0.05) associated with the fatty acid composition and Saturated Fatty Acid (SFA), i.e., tridecanoic acid (C13:0), arachidic acid (C20:0), henecosanoic acid (C21:0), and tricosanoic acid (C23:0). The polymorphism was also significantly associated with the Monounsaturated Fatty Acid (MUFA) i.e. ginkgoleic acid (C17:1) and nervonoic acid (C24:1), and Polyunsaturated Fatty Acid (PUFA) i.e. eicosedienoic acid (C20:2). The level of expression of the HSD17β13 gene based on quantitative real time-PCR analysis results was not significantly different (P>0.05) among genotypes for lamb quality traits. It can be concluded that the polymorphism of HSD17β13 gene was associated with the fatty acid composition of lamb in Indonesian sheep.","PeriodicalId":7887,"journal":{"name":"Animal production","volume":"1 1","pages":"44-53"},"PeriodicalIF":0.0,"publicationDate":"2021-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47000738","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 consisted of 2 parts of rice bran and 1 part of coconut meal. The ratio of concentrat and ammoniated rice straw was 50:50. Each treatment was repeated 6 times. The results showed that the concentration of acetic acid, butyrate and methane gas decreased while the concentration of propionate increased with the addition of red dragon fruit and guava leaves. The research concluded that the addition of 5 % red dragon fruit skin flour combined with 2.5 % guava leaves flour in beef cattle feed could further reduce the concentration of acetic acid, butyric acid and the production of methane gas, but increase the concentration of propionic acid.

Based on polynomial graph, the most efficient MPS was achieved on combination between DFMRK and 0.23% HLM about 8.70 gN/day.

The 2019 egg production in Central Java was 36.174 tons or 11.3% of the total egg production nationwide. Accordingly, it is important to investigate the effect of environmental factor, total number and age of ducks on egg production in Central Java. Specifically, this study aimed to observe the effect of region on egg production and feed conversion ratio (FCR) and the total livestock (chicken), age (month), stocking density (ducks/m2), internal housing temperature (oC), and humidity (%) on Hen day production/HDP. A survey engaging purposive random sampling was conducted on the population of duck farming in Central Java especially Tegal, Pemalang and Brebes districts. The data were subjected to General Linear Model (GLM) and a regression-correlation analysis using an SPSS program. The result showed that region significantly affected hen day production (HDP) but did not affect FCR. Housing temperature affected HDP by 14.9% and the higher the temperature, the lower the HDP. Duck age affected HDP by 11.7%, and the older the ducks the lower the egg production. Duck population, stocking density and humidity did not significantly affect egg production. Conclusively, duck egg production (HDP) is significantly affected by temperature inside the housing and the duck age.","PeriodicalId":7887,"journal":{"name":"Animal production","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44543752","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}
