Exogenous Cellulase Enzyme Supplementation in Complete Feed Based On Fermentation of Banana Stems for Nutritional Consumption of Beef Cattle

/in /by

The obstacle to increasing beef cattle production in East Nusa Tenggara, especially Timor Island, is that feed by farmers is still below the dry matter requirements for beef cattle. This fact shows that it is necessary to add supplements to the feed. Therefore, the exogenous addition of cellulase enzymes is a solution to increase the digestibility of feed in the rumen of beef cattle that consume high fiber feed in areas with a long dry season and only available feed in the form of agricultural and plantation waste. The main aim of this research is to determine the effectiveness of its use. cellulase enzyme exogenously at different levels of use. In this study,18 male Bali cattle were used, aged 1 – 1.5 years with a body weight range of 108-116 kg with an average of 112.79 kg and a CV of 5.72%. The research method used was an experimental method using a Completely Randomized Design (CRD) with 3 treatments and 6 replications. The treatments in this study were P0; Leucaena leucocephala forage 70% + complete feed 30%, P1 Leucaena leucocephala forage 70% + complete feed 30% + cellulase enzyme 10 grams/kg dry matter complete feed, P2; Leucaena leucocephala forage 70% + complete feed 30% + added cellulase enzyme 15 grams/kg dry matter complete feed. The results showed that the dry matter consumption (g/h/d) of treatment P0 was 2,624.26±10.9, P1 2,618.94±15.6, P2 2,681.69±36.1, organic matter consumption (g/h/d) treatment P0 2,148.93±9.0, P1 2,149.66±12.9, P2 2,200.75±29.9 and crude protein consumption (g/e/d) P0 557.05±2.3, P1 548.91±3.3, P2 549.58±7.7. The results of the statistical analysis showed that the treatment had a significant effect of P<0.05 on the consumption of dry matter, organic matter and no significant effect of P>0.05 on the consumption of crude protein in fattening Bali cattle. The conclusion of this research is that complete feed supplementation based on fermented banana stems with cellulase enzyme supplementation at different levels has an influence on increasing consumption of dry matter and organic matter, but has the same influence between treatments on crude protein consumption of fattening Bali cattle.

This research aims to determine the effect of using alternative energy sources in the form of banana tubers and rejected cassava in complete pellet feed with different levels on VFA, NH3 and pH levels in vitro. The method used in this research is an experimental method using a completely randomized design (CRD) with 4 treatments and 4 replications, the treatments in this research are: R0; complete feed pellets 40% banana weevil + 60% concentrate, R1; complete feed pellets 60% banana weevil + 40% concentrate, , R2; pelleted complete feed (40% cassava + 60% concentrate, R3; pelleted complete feed 60% cassava + 40% concentrate. The data obtained were analyzed using analysis of variance. Based on the results of statistical analysis, it showed that the treatment had a significant effect (p<0, 05) on VFA, NH3 and rumen fluid pH levels. The conclusion of this research is that based on the discussion above, it is concluded that the use of different energy source materials in complete pelleted feed is able to increase VFA production and NH3 concentration and rumen fluid pH in vitro to the best level. 40%.
