Abstract

The efforts to increase grass production can be done with effective fertilization but not negative impact to the environment. Substitution of inorganic fertilizer with organic fertilizer is one effort that can be done to maintain the physical, chemical and biological soilcharacteristics.This experiment aims to determine the effect of urea fertilizer substitution with bio-slurry fertilizer on the growth and production of Stenotaphrum secundatum grass.The experiment was conducted at Greenhouse, Research Station of Faculty of Animal Husbandry, Udayana University, Denpasar for 12 weeks. The design used was completely randomized design (CRD) with five combined treatments and five replications so that there were 25 pots of experimental unit. Combination treatmentconsists of B0: without bio-slurry fertilizer and urea fertilizer 300 kg/ha, B5: bio-slurry fertilizer 5 tons/ha and 250 kg/ha urea, B10: bio-slurry 10 tons/ha and 200 kg/ha urea, B15: bio-slurry fertilizer 15 tons/ha and 150 kg/ha urea, B20: bio-slurry fertilizer 20 tons/ha without urea fertilizer.Variables observed were growth, production and growth characteristics.The results showed that the substitution of urea fertilizer with bio-slurry fertilizer was significantly different (P <0.05) in variables of leaf number, number of branches, root length, leaf dry weight, dry weight of stem, total dry weight of forage, leaf dry weight ratio with dry weight of stem, leaf area and not significantly different (P>0.05) on variable length of segment, length of segment, number of tiller, root dry weight, root volume, top root ratio and chlorophyll content.Based on the research result, it can be concluded that the substitution of urea fertilizer 50% (150 kg / ha urea with 15 ton/ha bio-slurry) resulted in growth and production of Stenotaphrum secundatum grass which is not different from 100% urea fertilizer (300 kg / ha)Keywords:Fertilizer Substitution, Bio-Slurry, Growth,Production, Stenotaphrum secundatum

Abstract

Mount Agung eruption in August to December 2017, caused the evacuation of bali cattle to evacuation zones. This study aims to compare the quality of Bali cattle rations based on nutrient consumption, dry matter digestibility, and organic matter digestibility Bali cattle rations given before and during in evacuation zones. The first step is a survey conducted from January to April 2018 to farmers to gather information about the botanical composition given to bali cattle before and after in evacuation zones and sampling of feed ingredients (forages and concentrates). The second step is the analysis of ration samples in the laboratory from May to June 2018. The rations are made based on observations in evacuation zones and tabulation of questionnaire results data. Variables observed were consumption of nutrient rations including dry matter (DM) kg/h/d organic matter (OM) kg/h/d, crude protein (CP) g/h/d, crude fiber (CF) g/h/d , ether extract (EE) g/h/d, and gross energy (GE) k.kal/h/d and feed digestibility including dry matter digestibility (DMD) %, and organic matter digestibility (OMD)%. The results showed that the consumption of DM, OM, CP, CF, EE, and GE rations before in evacuation zones was 6.55 kg/h/d respectively, 5.87 kg/h/d, 1,174.77 g/h/d, 1697.42 g/h/d, 443.12 g/h/d, and 26,374.82 kcal/h/d, as well as in evacuation zones, each 6.61 kg/h/d, 5.88 kg/h/d, 1082.96 g/h/d, 1769.47 g/h/d, 405.34 g/h/d, 25,072.90 kcal/h/d. DMD and OMD of Bali cattle rations before in evacuation zones were higher, but the analysis of the two rations showed different results which were not significant so it was concluded that the two types of rations were of good quality.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh komposisi hijauan dengan level konsentrat yang berbeda dalam ransum terhadap komposisi tubuh dan retensi nutrien kambing PE. Lokasi penelitian dilaksanakan di Teaching Farm Fakultas Peternakan, Universitas Udayana Kampus Bukit, Jimbaran. Penelitian dilakukan selama 3 bulan dengan menggunakan rancangan acak kelompok (RAK) yang terdiri dari 3 perlakuan ransum dengan 3 kelompok berat badan ternak kambing sebagai ulangan. Peubah yang diamati adalah komposisi tubuh yakni kadar air tubuh, lemak tubuh, protein tubuh, dan retensi nutrien yakni retensi lemak, retensi protein, dan retensi energi. Komposisi tubuh ditentukan dengan cara sebaran ruang urea (Rule et al., 1986). Hasil penelitian menunjukkan kadar komposisi tubuh kambing PE yang diberi 15% rumput gajah + 20% jerami padi + 25% gamal + 10% kaliandra + 30% konsentrat menunjukkan kadar air dan protein tubuh paling tinggi akan tetapi kadar lemak tubuhnya paling rendah, namun secara statistik berbeda tidak nyata (P>0,05). Pada hasil kadar retensi nutrien menunjukkan pemberian ransum 15% rumput gajah + 20% jerami padi + 25% gamal + 10% kaliandra + 30% konsentrat menunjukkan hasil retensi lemak, retensi protein, dan retensi energi paling tinggi, namun secara statistik berbeda tidak nyata (P>0,05). Dari hasil penelitian yang dilakukan dapat disimpulkan bahwa pemberian komposisi hijauan yang beragam dengan level konsentrat yang berbeda pada ransum tidak berpengaruh terhadap komposisi tubuh dan retensi nutrient kambing PE.
