Abstract

This study was to evaluate the effect of different levels of Carica seed as a substitute for soybean meal in a total mixed ration in vitro. Parameters observed included physical characteristics of diet, nutrient digestibility (dry matter and organic matter), and rumen fermentation (pH, NH₃, and partial VFA). A completely randomized design with four treatments and five replications was applied. The treatments were T1 (85%complete feed+15% soybean meal + 0% Carica seed), T2 (85% complete feed + 10% soybean meal, 5% Carica seed), T3 (85%complete feed + 5% soybean meal + 10% Carica seed), and T4 (85%complete feed+ 0% soybean meal+ 15% Carica seed). This study showed that bulk density of T4 was highest among treatments and T1 was the lowest one (p<0.05). Moisture content and hardness in this study was similar among treatments (p>0.05). An average of moisture and hardness was 6.8% and 3.6 kgforce, respectively. The study showed that dry matter digestibility (DMD) of T1 (65.32%) was similar to T2 (64.00%) and higher than that of T3 (57.40%) and T4 (53.90%). Organic matter digestibility (OMD) of T1 (77.41%) and T2 (76.74%) was also similar and higher than that of  T3 (69.85%) and T4 (66.79%). Rumen fluid profiles also were not significantly different (p>0.05). An average of pH, NH₃, acetic acid, propionic acid, and A/P ratio was 6.58, 5.5 mM, 10.8 mM  and 1.5, respectively. However, butyric acid of T3 and T4 was similar and lower than that of T2 and T1 (p<0.05). Butyric acid of T1 was the highest among treatments (p<0.05). In conclusion, the use of Carica seed as the substitution of soybean meal decreased the bulk density without altering water content and hardness. Carica seed also reduced the digestibility of feed. The substitution of Carica seed did not alter rumen fluid profiles but butyric acid. Carica seed could be used as substitution for soybean meal up to 15% without altering nutrient utilization.

Abstract

The study aimed to evaluate the macro- and micromineral composition of soil and Gliricidia sepium leaves grown at three different altitudes and to assess their potential contribution as mineral sources for ruminant diets. Soil and Gliricidia sepium leaves were collected from 60 locations across 9 districts in Magelang, Central Java, Indonesia, using purposive sampling based on the largest cattle population and land altitude. The macromineral (Ca and Mg) and micromineral (Fe, Zn, and Cu) contents of the samples were determined using an Atomic Absorption Spectrophotometer. The results showed that lowland areas had higher (P<0.01) Ca and Fe contents in both soil and G. sepium leaves. Meanwhile, the concentrations of Mg, Zn, and Cu in both soil and plant samples did not differ significantly (P>0.01) among altitudes. Higher rainfall at higher altitudes may reduce Ca and Fe uptake due to increased nutrient leaching and changes in soil chemical properties. In addition, differences in temperature between lowland and highland areas might have influenced the Ca and Fe contents. Meanwhile, the Mg, Zn, and Cu contents were relatively stable, were not as easily leached by rainfall, and were less affected by altitude. The macromineral requirements for Ca and Mg in ruminants (beef cattle, dairy cattle, and sheep) were met by G. sepium at low, mid, and high altitudes in Magelang Regency, Central Java, Indonesia. Meanwhile, the micromineral requirements of ruminants were met only for Fe. Supplementation with other forages or feed additives is needed to meet the Zn and Cu requirements of ruminants.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh sinbiotik dari kombinasi Bacillus cereus dan Lactobacillus bulgaricus dengan ekstrak kulit kacang tanah untuk menurunkan kadar amonia, pH, dan kadar air ekskreta ayam kampung. Metode yang digunakan yaitu eksperimental rancangan acak lengkap (RAL) dengan 4 perlakuan dan 5 ulangan. Perlakuan penambahan sinbiotik terdiri dari konsentrasi 0% (P0) sebagai kontrol, 3% (P1), 6% (P2), 9% (P3). Parameter yang diukur meliputi kadar amonia, pH dan kadar air. Data yang diperoleh dianalisis menggunakan ANOVA dan dilanjutkan dengan uji Duncan Multiple Range Test. Hasil analisis menunjukkan bahwa terdapat pengaruh nyata konsentrasi sinbiotik dari kombinasi Bacillus cereus dan Lactobacillus bulgaricus dengan ekstrak kulit kacang tanah terhadap kadar amonia setelah inkubasi 12 jam, kadar pH setelah inkubasi 36 jam dan kadar air setelah inkubasi 36 jam. Perlakuan penambahan sinbiotik kurang efektif untuk menurunkan kadar amonia ekskreta ayam kampung diduga probiotik yang digunakan tidak mampu beradaptasi di dalam ekskreta sehingga mengganggu proses metabolisme primer dan sekunder.
