Abstract

Mulberry leave has a great potential as animal feed because of its high nutrient content. It also has deoxynojirimycin (DNJ) compound, that is potential to increase fermentability of fibrous feed in ruminal system. An in vitro experiment was conducted to investigate the capability of mulberry leaves to substitute concentrate as feed for ruminant in increasing fermentability of fibrous feed in ruminal system. This experiment was carried out using randomized block design with five treatments and four replications. The treatments were: P0 (50% rice straw + 50% concentrate) as a control, P1 (50% rice straw + 37.5% concentrate + 12.5% mulberry leave), P2 (50% rice straw + 25% concentrate + 25% mulberry leave), P3 (50% rice straw + 12.5% concentrate + 37.5% mulberry leave), P4 (50% rice straw + 50% mulberry leave). Variables measured were fermentability (NH3 and VFA concentrations), pH, gas production, dry matter and organic matter digestibility. Data were analyzed using analysis of variance and duncan multiple range test was further used to test the significant differences. VFA concentration, dry matter digestibility and organic matter digestibility were significantly difference (P < 0.05) among treatments. However, there was no significant effect on the other variables. It is concluded that mulberry leave are able to substitute the concentrate and increased fermentability of fibrous feed in ruminal system. Key words: mulberry leave, rice straw, ruminal fermentation, in vitro

Abstract

An experiment was conducted to assess the substitution of concentrate with mulberry (Morus spp.) leaves combined with rice straw offered to beef cattle. The study used 12 male Ongole grade cattle weighing 217+10.53 kg. Rations consisted of rice straw, mulberry leaves and concentrate. Research was carried out according to completely randomized design with 3 treatments and 4 replications for each treatment. The treatments were: P1= 50% rice straw + 50% concentrate; P2= 50% rice straw + 25% concentrate + 25% mulberry; P3= 50% rice straw + 50% mulberry. The results of the study indicated that rumen fermentation in cattlle fed on P2 ration was more effective than those receiving P1 and P3 rations. The fermentation was characterized by a higher production of total VFA and allantoin excretion in the urine. The presence of 1-deoxynojirimycin  (DNJ) compound of mulberry leaves in the rumen system in treatment P2 and P3 improved digestibility of fiber fractions of rice straw-based rations. Mulberry leaves in rations also accounted for isoacids in the rumen system, which supported the development of cellulolytic bacteria. In conclusion, mulberry leaves containing concentrate had a potency to substitute concentrate when used together with  fiber source feed such as rice straw.
