Abstract

Ninety six commercial strain were conducted from 14 to 42 days of age to evaluate the affect of utilization zeolite and on performance of broiler and fecal characteristics. Birds were divided into four  treatment diets (4 replicates of 7 birds each): K (control), KB (K+ 1% bentonite),  KZ (K+ 1% zeolite), KBZ (K+ 1% Z+ 1% B). The birds were fed initially for two weeks a commercial starter ration and followed by treatment  diets 15 to 42 days of age. All the diets were formulated to have 20% crude protein and 3000 kcal. ME and 0.91% Ca and 0.69% P for control and 0.34% treatments. Body weights and feed intakes were measured on a weekly basis. The manure from each group was sampled on weekly basis and the  moisture content, pH and ammonia production was determined. The results showed the utilization zeolite and bentonite or both significant differences (P<0.05) on pH and (P<0.01) fecal ammonia content, but not on feces water content, final body weight, feed consumption, feed conversion ratio, and carcass.

Abstract

Tujuan penelitian ini adalah menguji kemampuan sinergisme fungi selulolitik asal limbah jagung untuk dikonsorsiumkan sebagai bioaktivator pakan berserat. Isolate fungi selulolitik yang dikonsorsiumkan merupakan hasil isolasi dari limbah tanaman jagung yaitu isolate JB (Aspergillus sp.), JC (Fusarium sp.), JD (Aspergillus sp), JE (Rizoctonia sp.). Parameter yang diamati adalah sinergisme fungi selulolitik yang dikonsorsiumkan pada medium padat, pola interaksi antara fungi yang dikonsorsiumkan pada medium padat dan sinergisme fungi selulolitik yang dikonsorsiumkan pada medium cair (cocktail inokulum). Hasil penelitian menunjukkan bahwa dari konsorsium isolate fungi selulolitik diperoleh 5 pasangan isolat fungi selulolitik yang dapat bersinergi dan 1 pasangan tidak dapat bersinergi. Pola pertumbuhan yang terbentuk bersifat Mutual Intermingling (pasangan isolate JB vs JC dan JB vs JD), Partial Intermingling (pasangan isolate JB vs JE; JC vs JD; dan JD vs JE); dan Inhibition at touching point (pasangan isolate JC vs JE). Sinergisme fungi selulolitik yang dikonsorsiumkan pada medium cair (cocktail inokulum) menunjukkan tingkat pertumbuhan yang berfluktuatif seiring bertambahnya waktu fermentasi. Kesimpulan: dari 5 pasangan isolat fungi selulolitik yang dikonsorsiumkan diperoleh 1 pasang isolate yang tidak dapat bersinergis, dan sinegisme antara fungi membentuk pola interaksi yang bervariatif. Pertumbuhan fungi selulolitik pada medium cair berfluktuatif dan menunjukkan tingkat pertumbuhan optimum pada hari ke-3.

Abstract

The breeding of dwarf elephant grass generally uses vegetative methods, namely using cuttings. The constraints faced and the distribution of cuttings are the nature of which are easily damaged during storage due to physiological activities and invasion of microorganisms. This study aims to find a number of preservation techniques that can maintain the age and quality of dwarf elephant grass cuttings (Pennisetum purpureum cv mott.). This research was carried out in the Faculty of Agriculture Universitas Sumatera Utara, starts from July to August 2018. The design used is a 5 x 5 factorial complete randomized design (RAL), with 4 replications each consisting of 3 cuttings. The results showed that the general condition of the cuttings planting material was better until storage for 20 days, namely A4; the average shrinkage weight of the cuttings is significantly different in the A4 (refrigerator) treatment that is equal to 1.532 and the longer it is stored the higher the weight loss; the average power grows is significantly different in treatment A1 (wax) which is equal to 1.950 and the longer it is stored the lower the power to grow cuttings. The average vertical height is significantly different from the A1 treatment (wax) with a value of 10,585.
