Abstract

The research was carried out at the CV. Agriranch in Brak Village, Karangploso District, Malang Regency from May until June 2009. Proximate analysis was carried out at the Animal Nutrition Laboratory, Animal husbandry Faculty, Brawijaya University. Objective of this research was to investigate the effect of TDN level in the  concentrate for the in vivo digestibility.         The materials used were : (1) Nine fat-tailed rams with the initial body weight 14 kg: (2) Concentrate (3) Corn stover silage. The experiment used Completely Randomized Design with 3 treatments and 3 replications. The treatments were 3 levels of concentrate: P1 feeding concentrate level TDN 78%; P2 at level TDN 80%; P3 at level TDN 82% (3.12% DM from the body weight) and ad libitum corn stover silage. Variables examined were feed intake and digestibility. The result of the research showed that fat tailed sheep obtaining low TDN concentrate increased feed intake (P<0.05). The highest DM, OM, CP feed intake on the P1 were 97.85 g/kg body weight0.75/day; 85.66  g/kg body weight0.75/day; 17.59 g/kg body weight0.75/day. Fat tailed sheep obtaining low TDN concentrate its digestibility is lower than those with higher TDN concentrate (P<0.01). The highest DM, OM, CP digestibility on the P3 were 74.65%; 77.99%; 77.23%. Digestible consumption nutrient did not effect (P<0.05) except digestible consumption CP (P<0.01). The highest DM, OM, CP digestible feed intake on the P1 were 66.62 g/kg body weight0.75/day; 63.48 g/kg body weight0.75/day; 13.59 g/kg body weight0.75/day. The conclusion of the research was the increase of the feed intake was intended for fulfilling the energy need. The increase of the feed intake was caused by the increase of forage consumption, so the digestibility decreased. Digestible feed intake was influenced more feed intake than digestibility. Key words : concentrate, energy level, in vivo digestibility, fat-tailed sheep

Abstract

This trial was aimed to evaluate the performance of sweet potato cultivars on biochar application. The treatments were carried out using a Split-plot Design with three replications. The cultivars were placed on main plots and biochar doses were on sub-plots. The thirteen cultivars consisted of seven varieties and six accessions from Tribhuwana Tunggadewi University and Brawijaya University collections. The applied biochar doses were B0 (0 t/ha) and B1 (5 t/ha). The experimental unit measuring of 5 m x 0.6 m consisted of single row and planted with a spacing of 25 cm in row or 20 cuttings/row. The storage root weight, % dry matter, storage root dry weight, dry weight of biomass, harvest index and yield estimation were determined. The results showed that the sweet potato cultivars gave a significant response to the biochar application on fresh storage root weight, storage root dry weight, biomass dry weight, harvest index and storage root yields, but no interaction between cultivars and biochar doses. Storage root yield ranged from 8 to 21 t/ha without biochar and from 10 to 23 t/ha with 5 t biochar /ha, except for Beta 1 and Boko. The use of 5 t biochar /ha increased storage root yields that ranged from 8 to 45%.

Abstract

Indawan et al, 2019. Increasing Sweet Potato Yield on Biochar Amendment Application on Sub-Optimal Dry Land. JLSO 8(1):47-56. Biochar is a soil amendment that can improve soil fertility, increase crop yield and can reduce contamination. This study aim to evaluate the sweet potato response to biochar application from tobacco industry waste. The combination of cultivar and dose of biochar implemented using a Split Plot Experiment Design with three replications. The cultivars placed 0n main plots and biochar doses on sub-plots. The thirteen cultivars covering 7 varieties (Kuningan Putih, Beta 1, Beta 2, Kuningan Merah, Sari, Boko, and Jago) plus six accession from Unitri and Brawijaya University collections (BIS OP-61-OP-22 , 73-6 / 2, 73 OP-8, BIS OP-61, 73 OP-5, and BIS OP-61-♀-29). The biochar dose used was B0 (0 t / ha) and B1 (5 t / ha). The experimental unit is measuring 5 m x 0.6 m, consisting of single row and planted with a spacing of 25 cm in row or 20 cuttings/row). The storage root numbers, storage root weight, % dry matter, Harvest Index (HI) and yields estimation are ditermined. The results showed that sweet potato cultivars gave a significant response to biochar application on fresh storage root weight, dry storage root weight, biomass dry weight, HI and storage root yields, but no interaction between cultivars and biochar doses. Storage root yield range of 8 - 21 t / ha without biochar and 10 - 23 t / ha with biochar 5 t / ha, except for Beta 1 and Boko. The use of biochar of 5 t / ha can increase storage root yields ranging from 8 - 45%.

Abstract

Total Mixed Ration (TMR) is a technology development of silage. The aims of TMR is making feed to keep from microbia, but also contains nutrients to supply nutriens requirement.In the fermentation process have major obstacles in the long ripening. In the long period of the fermentation process which make decrease the nutrient content of feed due to used of feed nutrients by the microbes. TMR research still not optimal so make this research become important to conduct about optimal microbes in the fermentation process of the nutrient content in the manufacture of Total Mixed Ration especially based shoot sugarcane.The method of this research used completely randomized design (CRD) with directional pattern. This research used 2 treatments, the inoculum EM4 (P1) and without inoculum (P0); with the curing time of 0, 7, 14, and 21 days.The results showed that the use of inoculum EM4 in TMR shoot sugarcane can decrease crude fiber content of 29.31% to 24.9% at day 7 compared with the controls, which had decreased on day 21. In the dry matter (BK) there are significantly differences (p

Abstract

The aim of the study was to determine the effect of using green concentrate with crude protein content (CP) 16% using raw materials of Gliricidia maculata leaf flour, Leucaena leucochephala leaf flour, Caliandra calothyirsus leaf flour and Artocarpus heterophyllus leaf flour on feed intake and daily gain. The material used was 16 male Peranakan Etawa goats with an initial body weight of 29.41 ± 8.69 kg / head. The use of Gliricidia maculata leaf flour, Leucaena leucochephala leaf flour, Caliandra calothyirsus leaf flour and Artocarpus heterophyllus leaf flour with proportions (1: 1: 1: 1) in concentrates of 10%, 20% and 30%. Other constituent feed ingredients include milled corn, soybean meal, bran, minerals, salt, coconut cake, and molasses. The study used a randomized block design method (RBD) consisting of 4 treatments and 4 replications. P1 (basal feed + concentrate without addition of leaf flour), P2 (basal feed + green concentrate with 10% leaf flour), P3 (basal feed + green concentrate with 20% leaf flour), P4 (basal feed + green concentrate with 30% leaf flour), Basal feed given to goats during the study varied, namely Gliricidia maculata leaves, Leucaena leucochephala leaves, Tithonia diversifolia, Caliandra calothyirsus leaves, Chromolaena odorata, Manihot utilisima leaves, Ipomoea batatas leaves, Persea americana leaves, Artocarpus heterophyllus leaves, corn straw, Euphorbia hirta, field grass, and Cyanotis axillaris. The results showed the effect of green concentrate feed with a content of 16% CP and the addition of leaf flour as much as 30% in green concentrates, giving a significant effect (P
