Effect of Additional Feed Supplement Fermentation Shrimp Waste Extract on Digestibility in Sentul Chicken Growth Phase

This study aims to determine the effect of adding feed supplements of fermented shrimp waste extract in the ration on the digestibility of local chicken rations in the growth phase.The research was carried out in Jatinangor District as well as the Laboratory of Ruminant Animal Nutrition and Animal Feed Chemistry,Faculty of Animal Husbandry,Padjadjaran University,Sumedang.The method used in this study was experimental with a Complete Randomized Design(RAL).The data were analyzed by fingerprint test(ANOVA)with further tests using the Dunnet test.The object of this study consisted of 20 Sentul chickens raised from the age of 1 day to 12 weeks,divided into 5 treatments and 4 tests.The treatment consists of P0=Basal ration without the addition of feed supplement fermented shrimp waste extract,P1=Basal ration+0.5%feed supplement fermented shrimp waste extract,P2=Basal ration+1.0%feed supplement fermented shrimp waste extract,P3=Basal ration+1.5%feed supplement fermented shrimp waste extract,and P4=Basal ration+2.0%feed supplement fermented shrimp waste extract.The changes observed are the digestibility of dry matter,the digestibility of organic matter,and the digestibility of proteins.The results showed that the addition of feed supplements for fermented shrimp waste extract had a significantly different influence on the digestibility of dry matter,the digestibility of organic matter,and the digestibility of protein.This study concludes that the addition of a feed supplement of 2%fermented shrimp waste extract in the ration can produce a high ration digestibility value for Sentul chicken in the growth phase.

Effect of Fermented Shrimp Waste Level in Feed on Biological Value on Native Chicken

The purpose of the study was to determine the effect and obtain the level of use of fermented shrimp waste in the feed that produces the best biological value in native chickens.The study used 125 one-day-old chickens(DOC)placed in 25 cages randomly,containing five chickens reared for eight weeks.The study used experimental methods,and the experimental design used was a completely randomized design with five types of treatment,namely,feed without the use of fermented shrimp waste(R0),feed containing 5%fermented shrimp waste(R1),feed containing 10%fermented shrimp waste(R2),feed containing 15%fermented shrimp waste(R3),and feed containing 20%fermented shrimp waste(R4),each treatment was repeated five times.The observed variables were absorbed nitrogen,nitrogen stored in the body,and biological value.Data were analysed using ANOVA and Duncan's Multiple Distance Test.The results showed that the use of fermented shrimp waste at a level of 20%in feed resulted in the best biological value in native chickens.

Lentil straw(Lens culinaris): An alternative and nutritious feed resource for kids

The scarcity of feed resources with the continuously increasing cost of usual animal feeds urgently demands searching some alternate feeds for ruminants. In this study, Barberi male kids were divided into4 groups of 5 kids(body weight 17.5 ± 1.8 kg) in each group, and ad libitum fed lentil straw(Lens culinaris;LS), LS based total mixed ration(LSTMR), urea ammoniated LS(ALS) or ALS based total mixed ration(ALSTMR) for a period of 28 days. Results showed LS was a superior feed(CP, 9.2%) for kids, but having quite high crude fibre(CF; 39.6%) and Ca:P ratio(10:1). Urea ammoniation of LS was helpful for increasing the digestible crude protein(DCP)(P < 0.01), nitrogen-free extract(NFE) and total digestible nutrients(TDN) with reduction of CF content. Urea mmoniation also improved the digestibility of neutral and acid detergent fibre(P < 0.01), but its effect on CP digestibility was negative(P < 0.05). Dry matter(DM), DCP and TDN intakes(per kg W0.75) were also improved(P < 0.01) in the kids fed ALS. Negative growth rate and nitrogen(N) balance(-33.8 and -1.4 g/day, respectively) in kids fed LS became positive(46.9 and 2.0 g/day, respectively) when ALS was used in the diets of kids. Feeding of ALS also increased(P < 0.01) the total N and ammonia N content of strained rumen liquor(SRL). Use of straw(LS or ALS) in TMR increased the digestibility of DM, organic matter and NFE(P < 0.01), intake of energy, as well as total volatile fatty acids concentration(P < 0.01) in the SRL. The present study suggested that optimum performance of kids may be achieved using either ALS alone or TMR with LS or ALS.
