Parameters of Protein Metabolism in Goats Fed Diets With Different Portion of Sugarcane Bagasse

Abstract

ABSTRAKLimabelas ekor kambing Jawarandu jantan digunakan untuk mengkaji pengaruh porsi ampas tebu dalam pakan terhadap beberapa parameter metabolisme protein. Ternak memiliki rerata bobot badan sebesar 18 kg dengan rerata umur 18 bulan. Ternak ditempatkan pada kandang metabolisme dan dialokasikan sesuai rancangan acak lengkap yang menerima tiga jenis pakan perlakuan, dengan porsi ampas tebu sebesar 15, 25, dan 35%. Setelah delapan minggu masa adaptasi terhadap pakan dan lingkungan perlakuan, setiap kelompok perlakuan menjalani uji kecernaan pakan, dan pengambilan sampel cairan rumen. Parameter yang dikaji adalah kecernaan pakan, retensi nitrogen, fermentasi ruminal, dan ekskresi alantoin untuk mengestimasikan sintesis nitrogen mikroba. Data diuji dengan sidik ragam dan dilanjutkan dengan uji wilayah ganda Duncan. Konsumsi bahan kering dan protein menurun nyata (P<0.05) selaras dengan peningkatan porsi ampas tebu dalam pakan. Kecernaan dan retensi nitrogen tidak dipengaruhi secara nyata oleh perlakuan porsi ampas tebu. Perlakuan pakan tidak berpengaruh secara nyata terhadap konsentrasi amonia, VFA total, asetat, propionat, dan butirat rumen. Sintesis nitrogen mikroba dan efisiensi sintesis nitrogen mikroba tidak berubah nyata akibat perlakuan porsi ampas tebu dalam pakan.Kata kunci: ampas tebu, sintesis nitrogen mikroba, kambing ABSTRACTFifteen Jawarandu male goats were used to study the effect of different portion of sugarcane bagasse in diets on some parameters of protein metabolism. Goats had average of body weight of 18 kg and aged at 18 months. Animals were housed in metabolic cages and were alloted to a completely randomized design receiving three experimental diets with sugarcane bagasse portions of 15, 25, and 35% (dry matter basis), respectively. After eight weeks of adjustment period to experimental diets and environment, each group of treatment was subjected to ten days of digestion trial, and followed by collection of rumen liquid samples. Parameters observed were feed digestibility, nitrogen retention, ruminal feed fermentation, and excretion of urinary allantoin to estimate microbial protein synthesis. Data were tested using one way analysis of variance, and followed by Duncan's mulitiple range test. Dry matter and protein intakes lowered (P<0.05) as the increasing of sugarcane bagasse in diets. Protein digestibility and retention were unaffected by the treatment of bagasse portion. The dietary treatment did not change ruminal ammonia, total VFA, acetate, propionate, and butyrate concentrations. Microbial nitrogen synthesis and efficiency of microbial nitrogen synthesis were unaffected by the dietary treatment.

The Utilization of Coconut Coir as Supplementary Feed for Beef Cattle Production

“…As shown in Table 4, the purine derivatives were not significantly different among the four treatments. Ariyani et al (2016) found that purine derivatives were not significantly different (P > 0.05) when using bagasse as basal feed. Purine derivatives reflect that the use of FCC does not interfere with the digestive system in cattle.…”

Effect of Synchronization of Carbohydrate and Protein Supply in the Sugarcane Bagasse Based Diet on Microbial Protein Synthesis in Sheep

“…Sugarcane bagasse is one of agricultural wastes that frequently used to sustain roughage availability for ruminant throughout the year. Previously, the maximum level of sugarcane bagasse in TMR for goat was determined to be 25% (Ariyani et al, 2014). By synchronizing ruminal releases of energy and protein, the use of sugarcane bagasse in diet is expected to be more efficient.…”

Synchronization of Carbohydrate and Protein Supply in the Sugarcane Bagasse Based Ration on in Situ Nutrient Degradability

“…The portion of sugarcane bagasse in TMR was the highest among ingredient feedstuffs (Table 2). Most fiber components of sugarcane bagasse are tightly bound to lignin as lignohemicelluloses and lignocelluloses (Ariyani et al, 2014;Ramli et al, 2005).…”
