Abstract

The research was aimed to determine the effect of season on feed quantity and quality, and growth performance of male Bali cattle fattened in smallholder farms. Observation from January to March for rainy season and June to August for dry season. Feed quantity and quality were observed covering all feedstuff used farmers in fattening. Cattle used for rainy season was 50 heads aged 1.5 – 4.0 years with initial body weight (BW) 188.03±31.85 kg. In dry season, observation was continued for the same cattle as many as 35 heads aged 2.0 – 4.5 years and initial BW was 261.80±38.46 kg. Data were analyzed by quantitative descriptiption for feed quantity and quality, while growth performance were analyzed by independent T-Test. Results of study showed the dominant type of feedstuff used during rainy and dry season were L.leucocephala (56.00 vs 33.14%), Zea mays fresh straw 18.44% (rainy season), natural grass (13.00 vs 22.25%), P.purpuroides (3.68 vs 3.99%) and G.sepium (1.36 vs 29.69%). Crude protein (CP) of L.leucocephala and G.sepium higher during the dry season, while S. grandiflora, natural grass, and P.purpuroides higher in rainy season. The DMD (%) of L. leucocephala and S. grandiflora in rainy and dry seasons were almost the same, but G.sepium had DMD higher in dry season. The OMD L.leucocephala and G. sepium higher during the dry season, while the S.grandiflora had higher during the rainy season. Natural grass and P.purpuroides had DMD and OMD higher during the rainy season. Dry matter intake (kg/head/day) of cattle during dry season was higher (P<0.01), but rainy season ADG and FCR was higher (P<0.01). It can be concluded the feed used by farmers during the rainy season was more varied, with better quality. As a result, the performance of Bali cattle fattened was higher in the rainy season than in the dry season.

Abstract

This study aimed to determine the in vitro nutrient digestibility of complete silage from Sorghum bicolor (L.) Moench using different additives. The method used was a completely randomized design containing 4 treatments and 4 replications, namely, R1: Sorghum bicolor (L.) Moench + L. leucocephala (without additives/control), R2: Sorghum bicolor (L.) Moench + L. leucocephala + 20% rice bran + 10% rock sugar, R3: Sorghum bicolor (L.) Moench + L. leucocephala + 20% corn meal + 10% rock sugar, R4: Sorghum bicolor (L.) Moench + L. leucocephala + 20% pollard + 10% rock sugar. The additive material percentage was calculated based on the chopped weight of Sorghum bicolor (L.) Moench and L. leucocephala. The data obtained were assessed by the analysis of variance, and then continuously analyzed by the Duncan's multiple range test. The Sorghum bicolor (L.) Moench plants were harvested on 70 days after planting and withered for 3 hours to reduce the moisture content, and then chopped at 3 cm size. The chopped results were mixed with the additive materials based on the treatments and their percentages applied, and then moved to the plastic container (silo), the mixture that was moved into the silo was suppressed to make the chopped layer solid (anaerobic principal). Ensilage process was stood for 21 days. The complete silage was removed, and its in vitro nutrient digestibility was analyzed. The results showed that the use of additives could improve the dry matter, organic matter, N-NH3, and VFA digestibility of complete silage from Sorghum bicolor (L.) Moench. It can be concluded that the additive supplementation of 20% pollard and 10% rock sugar can improve the dry matter, organic matter, N-NH3, and VFA digestibility of complete silage from Sorghum bicolor (L.) Moench.
