Forage samples were dried at 60oC for 24 hours, then ground to 1 mm sieve. The ground samples were used subsequently to determine the chemical composition and in vitro rumen fermentation test. Incubation was carried out in a water bath at 39oC for 48 h without replication. The results showed that all forages contained various crude protein at a range of 9-20% DM. The proportion of neutral detergent insoluble CP (NDICP) and acid detergent insoluble CP (ADICP) in forage was generally low, but the highest was found in bede grass. The highest NH3 concentration was found in Indigofera incubation, and lowest was in bede grass. All forage samples, except for mini elephant grass and Indigofera, had IVDMD and IVOMD below 70%. We identified low methane emissions from forage at 48 hours of incubation. It was concluded that legumes had a higher crude protein than in grass species and had low methane emissions. However, the relatively low digestibility of legume may limit its utilization.","PeriodicalId":7887,"journal":{"name":"Animal production","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41605130","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 purpose of this research was to determine the morphometrics of the Kacang Goats at the fishpond area in Sidoarjo Regency based on different ages and sex. The fishpond area in Sidoarjo is a closed area where goats are raised and have the potential for inbreeding with the consequence of smaller-sized offspring than normal.  Morphometric measurements included the head, ears, neck, body, legs, tail, and horns. This research used a descriptive analysis approach, presenting data in form of mean, standard deviation, and coefficient of variation. The result showed that the average face length of male vs. female Kacang goats was 16.73 ± 2.40 cm vs. 19.68 ± 2.44 cm; with a face width of 11.25 ± 2.91 cm vs. 19.52 ± 3.18 cm; ear length of 14.62 ± 1.38 cm vs. 16.46 ± 1.47 cm; neck length of 15.53 ± 2.65 cm vs. 15.35 ± 2.14 cm; horn length of 7.41 ± 4.10 cm vs. 6.59 ± 2.89 cm; chest circumference of 59.33 ± 8.18 cm vs. 67.80 ± 6.32 cm; body length of 51.45 ± 6.70 cm vs. 56.91 ± 6.54 cm; body height of 54.41 ± 7.22 cm vs. 62.01 ± 5.53 cm; tail length of 13.21 ± 2.01 cm vs. 14.77 ± 3.37 cm; hind leg length of 39.20 ± 5.26 cm vs. 47.74 ± 5.47 cm; and front leg length of 37.00 ± 8.84 cm vs. 44.63 ± 8.65 cm.

Each treatment was replicated four times with 25 chicks per replicate. The feeding trial was conducted from the age of 8th to 35th days of age. The acidifier used was a blend of activated charcoal, selenium, vitamin E, probiotics, prebiotics, mannan oligosaccharides, and bacterial cell wall components. The results showed significant effects (P<0.05) on the broilers' body weight gain, average daily gain, and feed efficiency from 8 to 14 days of age.

Bioactive peptides improve the health status of humans and animals. Protein hydrolysis produce peptides that are safe, quickly metabolizable, less risky for livestock products to have contaminant residue. Bioactive peptides are still bound to the original protein, so they need to be released through an enzymatic process. This research explored the potential of chicken slaughterhouse waste to produce biopeptides by hydrolyzing proteins using various proteolytic enzymes. The slaughterhouse waste included chicken feet, intestines, filleting waste and blood plasma. The proteolytic enzymes used were papain, bromelain, protease by Rhizopus oligosphorus, probiotic protease. The observed variables were dissolved protein content with and without precipitation, protein hydrolyzate content, and the degree of enzyme hydrolysis. The research was conducted using exploratory methods. The results showed that the dissolved protein content in the chicken slaughterhouse waste protein concentrate was 1,585 mg/ml (feet), 2,361 mg/ml (intestines), 1,787 (filleting waste) and 2,372 mg/ml (blood plasma). Blood plasma protein concentrate showed the highest yield among other chicken slaughterhouse waste protein concentrates, namely 0.14 mg/ml (hydrolysis of papain), 0.18 mg/ml (hydrolysis of bromelain), 0.56 mg/ml (hydrolysis of R.oligosphorus protease) 0.68 mg/ml (hydrolysis of probiotic proteases). The highest degree of hydrolysis was shown in blood plasma hydrolyzates using probiotic protease enzymes, namely 28.72%. The highest antioxidant activity was 92.92% as observed in chicken feet protein hydrolyzate which was hydrolyzed using papain.  Therefore, chicken feet, intestines and fillet waste can produce protein concentrates through precipitation using ammonium sulfate, and plasma using acetone. The highest protein concentration was in blood plasma protein which also produced the highest hydrolysis from hydrolyzing blood plasma proteins with hydrolyzed probiotic protease. The highest antioxidant activity was observed in chicken feet protein hydrolyzate which was hydrolyzed using papain enzyme and incubated for 6h.","PeriodicalId":7887,"journal":{"name":"Animal production","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42853040","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}
