<p>This research was aimed to investigate the effect of concentrate substitution with cassava plantation waste supplemented with cobalt and zinc in sheep ration. In vitro study was used in this experiment. Collected data were analyzed by Duncan’s test from Completely Randomized Design with four treatments and four replications. The experiment rations were R1 = 50% native grass + 50% concentrate, R2 = 50% native grass + 50% concentrate + 5 ppm cobalt + 30 ppm zinc, R3 = 50% native grass + 50% cassava plantation waste, R4 = 50% native grass + 50% cassava plantation waste + 5 ppm cobalt + 30 ppm zinc. The results showed that utilization of concentrate increased volatile fatty acid and N-NH3 concentration, and digestibility of dry and organic matter compared with cassava plantation waste. Volatile fatty acid and N-NH3 in sheep ration containing cassava plantation waste were still in normal range with dry and organic matter digestibility were up to 50%, but supplementation of cobalt and zinc had the same effect (P&gt;0.05). It is concluded that cassava plantation waste can be used as sheep feed, but did not substitute concentrate. Supplementation of cobalt and zinc was not effective to improve fermentability and digestibility of cassava plantation waste.</p><p><br />(Key words: Cassava plantation waste, Digestibility, In vitro, N-NH3, Sheep, Volatile fatty acid)</p>

Sementara itu, terjadi kenaikan konsentrasi N-NH3 (3,87 - 4,90 mM) sampai penggunaan limbah roti 30%, namun penggunaan 40% limbah roti sama dengan ransum kontrol. Konsentrasi ALT memiliki hubungan erat dengan kecernaan bahan kering dan bahan organik dengan nilai r = 0,67 dan 0,65, pada persamaan regresi Y = 0,1591X + 50,79 dan Y = 0,1528X + 39,619. Kesimpulan, Penggunaan limbah roti di dalam ransum sebanyak 40% tidak mengganggu fermentabilitas dan kecernaan ransum secara in vitro.  (In vitro fermentability and digestibility of sheep rations containing bread waste)ABSTRACT. The study aimed to determine the fermentability and digestibility of sheep rations containing bread waste. The study used a completely randomized design with five types of treatment rations consisting of 40% native grass and 60% concentrate and each treatment containing bread waste as much as 0 (control), 10, 20, 30, and 40%. Each treatment was repeated 4 times and the data collected was analyzed by analysis of variance and continued by Duncan test. The treatment ration was evaluated by in vitro. The variables measured were volatile fatty acids (VFA), N-NH3, dry matter digestibility, and organic matter digestibility. The results showed that the use of bread waste in sheep rations up to 40% was able to increase the concentration of VFA (102.63 to 143.88 mM), dry matter (64.66 to 78.61%) and organic matter digestibility (53.41 to 65.82%). Meanwhile, there was an increase in the concentration of N-NH3 (3.87 to 4.90 mM) until 30%, but the use of 40% bread waste was the same as the control ration. The VFA concentration has a close relationship with the dry matter and organic matter digestibility with values of r = 0.67 and 0.65, in the regression equation Y = 0.1591X + 50.79 and Y = 0.1528X + 39.619. The conclusion is using of bread waste as much as 40% did not disturb the fermentability and digestibility of the ration in vitro.

Oat and rape straws were treated with NaOH (70 and 40 g kg-1, respectively) by spraying with NaOH solutions (20 or 12.5% w/w), consolidating the sprayed straw into stacks, and storing under plastic. After storage for up to 60 weeks, in vitro digestibilities had been approximately doubled, although it appeared that the reaction was complete by 4 weeks. Potential digestibility of straw organic matter estimated by a polyester bag technique, was increased by c. 0.1 by NaOH treatment but the rate of digestion in the rumen was not changed. Following storage, treated and untreated straws were dried, ground, mixed with supplements and pelleted for feeding to sheep. Mixtures of treated or untreated oat straw, minerals, c. 3% urea and 0, 14, 28 or 42% starch were fed to mature wethers. The main effects of NaOH treatment of straw were to increase water intake, digestibilities of organic matter and cellulose, and rumen volatile fatty acid levels, and decrease rumen ammonia levels. Low intakes of NaOH-straw with no added starch were associated with high rumen pH (> 7.5 , probably due to unreacted alkali (equivalent to 23 g NaOH kg-1). Inclusion of starch, but not NaOH-straw treatment, improved dietary N utilization, although mean N balances were negative (- 5.5 to - 0.1 g day-1) on all diets. Feeding treated straw increased the amounts of Na eaten, and of Na and P apparently absorbed; the extra absorption was accounted for by increased urinary excretion so that retention was not increased. When diets of rape straw supplemented with urea and minerals were fed to 2-year-old wethers, NaOH treatment of straw increased intakes of food and water, organic matter digestibility, rumen volatile fatty acid concentration and N balance.

The influence of the ratio of fermented rice straw, rice bran and cassava solid waste upon the In vitro digestibility and rumen fermentation productABSTRACT. Chemical and physical treatments have been attempted to improve the utilization of agro industrial wastes, but the result is not efficient and caused pollution. Besides, biological treatments using the microbes have been used to improve the nutritive value and utilization of agro industrial wastes. The current experiment was conducted to find out the optimal ratio of fermented rice straw, fermented rice bran and fermented tapioca waste. There were five kinds of ratio of fermented rice straw, fermented rice bran and fermented tapioca waste, namely: K1 (70% fermented rice straw + 15% fermented rice bran + fermented tapioca waste), K2 (60% fermented rice straw + 20% fermented rice bran + 20% fermented tapioca waste), K3 (50% fermented rice straw + 25% fermented rice bran + 25% fermented tapioca waste), K4 (40% fermented rice straw + 30% fermented rice bran + 30% fermented tapioca waste) and K5 (30% fermented rice straw + 35% fermented rice bran + 35% fermented tapioca waste) An in vitro technique, using completely Randomize Block Design was applied and each treatment was repeated four times. Variables measured were Dry matter and Organic matter digestibility and rumen fermentation products (volatile fatty acid and N-NH3 concentration). The dry matter digestibility of K1, K2, K3, k4 and K5 was 29.39, 31.27, 32.33, 33.71 and 34.82%, respectively. The organic matter digestibility of K1, K2, K3, K4 and 5 was 30.82, 31.27, 32.73, 34.94, and 34.92, respectively. Volatile fatty acid concentrations of K1, K2, K3, K4 and K5 were 95.19, 91.77, 87.21, 104.31, 106.59 mM/l, respectively. N-NH3 concentrations of K1, K2, K3, K4 and K5 were 0.97, 0.93, 0.93, 1.00, 1.04 mM/l, respectively. Significant difference (P0.01) was only found in dry matter digestibility among treatments, while others variables were not significantly different among treatments. It was indicated that the optimal ratio was K4.

The current work aimed to screen the ruminal cyanide-utilizing bacteria and evaluate the influence of fresh cassava root (FCR) and pellets containing high sulfur (PELFUR) on cyanide content, kinetics of gas, in vitro degradability, and ruminal fermentation. The experiment was conducted in a Completely randomized design (CRD) for a screening of cyanide-utilizing bacteria and the dietary treatments were the level of cyanide at 0, 150, 300, and 450 ppm. A 5 &times; 3 factorial arrangement in a Completely randomized design was used for in vitro study. Factor A was the level of FCR at 0, 260, 350, 440, and 530 g/kg of 0.5 g dry matter (DM) substrate, and factor B was the level of PELFUR at 0, 15, and 30 g/kg DM substrate. Adding different doses of cyanide significantly affected cyanide-utilizing rumen bacterial growth (p &lt; 0.05). Increasing the concentration of cyanide from 0 to 150 and 150 to 300 ppm, resulted in an increase in cyanide-utilizing rumen bacteria of 38.2% and 15.0%, respectively. Increasing the FCR level to more than 260 g/kg of 0.5 g substrate could increase cumulative gas production (p &lt; 0.05), whereas increasing doses of PELFUR from 15 to 30 g/kg increased the cumulative gas production when compared with that of 0 g/kg PELFUR (p &lt; 0.05). Cyanide concentration in rumen fluid decreased with PELFUR (p &lt; 0.05) supplementation. Degradability of in vitro dry matter and organic matter following incubation increased at 12 and 24 h due to PELFUR supplementation with FCR and increased additionally with 15 g/kg PELFUR (p &lt; 0.05) in 440 g/kg FCR. Proportions of the total volatile fatty acids, acetic acid (C2), propionic acid (C3), and butyric acid, as well as the ratio of C2 to C3 among supplementations with FCR (p &lt; 0.05) were significantly different. As the proportion of FCR increased to 530 g/kg of the substrate, the volume of C3 increased by 14.6%. This is the first finding of bacteria in the rumen capable of utilizing cyanide, and cyanide might function as a nitrogen source for bacterial cell synthesis. Inclusion of FCR of 530 g/kg with 30 g/kg PELFUR could increase the cumulative gas production, the bacterial population, the in vitro degradability, the proportion of C3, and the rate of the disappearance of cyanide.
