UJI PALATABILITAS PAKAN PEDET PRA - SAPIH BERBASIS DAUN INDIGOFERA YANG DI SUPLEMENTASI TEPUNG MAGOT BSF

Mutia Puji Rianty Arfan Abrar Langgeng Priyanto

Death of calves in community farms is still quite high because of breeders who pay less attention to the quality of feed that plays an important role in calf growth and development. In this study calf starter calf was made. Calf starter is a concentrate for early growth that is nutrient dense, low in coarse fiber and soft-textured, calf starter is given while the calf is still in the suckling period. The purpose of this study is to reduce the mortality rate of calf and accelerate weaning by using indigofera leaf-based calf and Maggot BSF flour. This research was carried out in November to December 2019 in the Field Laboratory of Animal Husbandry Study Program at the Faculty of Agriculture, Sriwijaya University. This research was conducted by giving a calf starter. The variables observed in this study included palatability to the type of feed given and consumption behavior consisting of sniff frequency, licking frequency and chewing frequency. Analysis of the data obtained will be presented and analyzed using descriptive tests. The results showed palatability and consumption behavior of calf starter livestock gave a positive response to calf starter given.

) leaves meal in rations on nutrient digestibility, hematological status and malondialdehyde levels in broiler chicken blood. The study was conducted experimentally with a completely randomized design, which consisted of 5 treatments and 5 replications. The treatment was the use of a combination of cassava tuber and indigofera leaves meal (70%+30%; CCI) in the ration, namely: T0 (0% CCI in the ration), T1 (5% CCI in ration), T2 (10% CCI in ration), T3 (15% CCI in ration) and T4 (20% CCI in ration). The material used was 100 day-old broiler chick (Cobb strain), which were placed in 25 postal cage units. The feed used was commercial broiler chicken feed: a mixture of concentrate, corn, rice bran and fishmeal, and CCI according to the treatment. The observed variables were nutrient digestibility (dry matter, crude protein and crude fiber), hematological status and blood malondialdehyde levels in blood of broiler chickens. Data were analyzed by ANOVA and further tested by Duncan Multiple Range Test (DMRT). The results of this study indicated that the CCI had a significant (P<0.05) effect on nutrient digestibility, hematological status and malondialdehyde levels in blood of broiler chicken. The CCI at a level of 10% in the ration increased hemoglobin levels by 17.09% and reduces malondialdehyde levels by 14.28% in broiler blood compared to commercial feed (control group). The results suggested that combination of cassava tubers and indigofera leaves (CCI) at a level of 10% could be used in broiler production without deteriorating the health of birds.

Riswandi Riswandi Arfan Abrar Agus Wijaya Basuni Hamzah

Swamp forage (kumpai grass), waste products from plantations, and agricultural industries are alternative feed for ruminants. To increase the value of its availability, yeast supplementation is needed. This study aimed to determine the effect of kumpai grass-based ration supplemented with cassava leaves, palm oil sludge, yeast on digestibility, rumen fermentation characteristics, and methane gas production. This study was determined using a Completely Randomized Design consisting of four treatments. The treatment is described as follows 70% grass + 30% Concentrate (P0, Con), 55% grass + 30% cassava leaves + 15% Concentrate + 0.05% yeast (P1), 55% grass + 30% palm oil sludge + 15% concentrate + 0.05% yeast (P2), and 55% kumpai grass + 15% cassava leaves + 15% palm oil sludge + 15% concentrate + 0.05% yeast (P3). Each treatment was incubated In-Vitro with a buffer solution (pH 6.9) and rumen of four replications (each repetition represented by three incubation bottles) for 48 hours at 39 ºC. The data obtained were analyzed for variance; if there were a treatment effect, the Duncan test can be further tested. The results showed that supplementation affected the increase (P <0.05) of dry matter digestibility, organic matter, crude protein, neutral detergent fiber, acid detergent fiber, total volatile fatty acids (total VFA), partial VFA, and total bacteria. Whereas, N-ammonia (N-NH3), the ratio of acetate-propionate and methane gas has decreased. It was concluded that supplementation of 15% cassava leaves, 15 % palm oil sludge, and 0.05% yeast in kumpai grass-based rations gave the best increase in the ration digestibility, total rumen bacterial count, rumen fermentation characteristics, and reduced methane concentration.

PENGARUH PELET Indigofera zollingeriana YANG DIPERKAYA DENGAN TEPUNG MAGGOT BSF SECARA IN VITRO TERHADAP KECERNAAN BAHAN KERING, pH DAN PRODUKSI GAS

Eka Novianti Arfan Abrar Langgeng Priyanto

The need for rations for pre-weaning calves is often overlooked, given the rumen is considered to have worked perfectly. Physiologically the rumen is not perfect so it requires feeding with low fiber content to be able to stimulate the growth of livestock. The nutritional needs of ruminants do not only depend on energy derived from fibrous feed but also from feed with protein sources. To meet the protein requirements of ruminants, research needs to be done by combining animal protein sources with vegetable protein. Vegetable protein used is legume Indigofera zollingeriana and animal protein used is maggot BSF. The purpose of this study was to determine the effect of Indigofera zollingeriana pellets enriched with maggot flour on Dry Material Digestion, pH and gas production in vitro. This research was conducted in September - December 2019 at the Laboratory of Animal Nutrition and Food, Department of Animal Husbandry Technology and Industry Department of Animal Husbandry, Faculty of Agriculture, Sriwijaya University. The study was conducted in vitro using an experimental method with 2 treatments. The data obtained were analyzed using the t-test statistical analysis method. The results showed that Indigofera zollingeriana pellets enriched with maggot flour were not significantly differentto the digestibility value of dry matter, pH and gas production. The dry matter digestibility value increased by 2,19%, The pH value of P1 and P2 is 7 and gas production decreased by 3,9 mL /hour.
