Abstract

The objective of this research was to evaluate the use of fermented rice straw by probion on feed consumption, digestibility, daily gain and feed efficiency of Simmental cow. This study was carried out based on completely randomized design, with here dietary treatments and four replications for each treatment. The treatments were R1 (JP-15) = 40% elephant grass + 15% untreated rice straw + 45% concentrate; R2 (JPF-15) = 40% elephant grass + 15% fermented rice straw + 45% concentrate; and R3 (JPF-35) = 20% elephant grass + 35% fermented rice straw + 45% concentrate. Concentrate was given at around 08:00 while unfermented/fermented rice straw was given afterward at around 09:00. Chopped elephant grass was given twice a day at 11:00 and 16:00. Water was available through out the day. Observation was done for two months on feed consumption, digestibility, daily gain and feed efficiency. The results did not show significant differences on feed consumption, digestibility, daily gain and feed efficiency, except on digestibilities of cellulose and hemicelulose. The digestibilities of cellulose and hemicelulose of treatment R3 was higher than that of R1 and R2. It is concluded that fermented rice straw is suggested to be used as an alternative feed to substitute elephant grass in maintaining feed consumption, digestibility, daily gain and feed efficiency of Simmental cow.

Abstract

Indigofera sp is a tree leguminous forage species known to be adaptable to the drought climate and saline soil and so it has potential as alternative feed resource to support the ruminant animal production. This study aimed to study the  responses of goats fed Indigofera sp as the sole foliages in their diets. Twenty male Boer x Kacang crossbred goats  (6 months of age;16 ± 2,1 kg BW) were randomly assigned to four dietary treatments containing fresh or wilted leaves of Indigifera sp. as the sole foliages and supplemented with high carbohydrate (HCC) or protein (HPC)concentrates. Consumable parts i.e. leaves and twigs of about 8 to 10 months of age of Indigofera sp. were harvested by hand plucking every day in the morning. The experiment was a 2 x 2 factorial design arranged in a completely randomized design. The ruminal pH ranged from 6.14-6.85 and were  not affected (P > 0.05) by wilting nor by the type of concentrates. Wilting did not affect (P > 0.05) the concentration of  ruminal NH3-N, but  it was significantly higher (P < 0.05) in HPC group (32.36-32.54 mg dL-1) than those in HCC group(17.94-23.57 mg dL-1). Total VFA concentration were not affected by wilting  nor by the type of concentrates  (P > 0.05). Goats in the HCC group,however,numerically have higher total VFA concentration (178.5-183.75 mmol L-1) than those in the HPC group (142.21-174.64 mmol L-1). The apparent digestibility coeficients  of DM, OM, CP and energy of the diet were not different (P > 0.05) when contained wilted or fresh Indigofera foliage.  Significant increases (P < 0.05)   in the DM and  OM, but not in the CP and energy  apparent digestibility coeficients were observed in the HPC goats. Dry matter intakes were not different (P > 0.05) among dietary treatments, but the ADG of goats in the HCC group (60-63 g d-1) were significantly lower (P < 0.05) than those  of goats in the HPC treatment (80-87 g d-1). Blood glucosa concentration was not affected by wilting nor by type of concentrates (P > 0.05).  BUN was not affected by wilting process, but providing high protein concentrates significantly (P < 0.05) increased the BUN concentration. It is concluded that foliage of Indigofera sp could be used as the sole forage in intensive production of goats. Wilting the foliage prior to feeding seemed to be unnecessary, since this process does not improve the animal productivity in term of daily gain and efficiency of feed utilization.

Abstract

Zinc is an element of many enzymes and hormones having very important physiological functions in the body so that it influences the production and reproduction of animals including the activity of the rumen microflora in degrading fiber in a diet. The aim of this study was to improve the performances of goats offered oil palm fronds based diets through the supplementation of 35 ppm of Zn in the form of inorganic (ZnO) and organic zinc (Zn-methionine). Thirty mature male crossing Boer x Kacang (Boerka) goats were divided into five groups and randomly allocated to one of the five feed treatments as follows: P1: complete feed based on the palm oil fronds (Control), P2: P1 + 35 ppm Zn (100% Zn0), P3: P1 + 35 ppm Zn (75% Zn0 + 25% Zn-methionine), P4: P1 + 35 ppm Zn (50% Zn0 + 50% Zn-methionine), P5: P1 + 35 ppm Zn (25% Zn0 + 75% Zn-methionine). The experiment was conducted in a Completely Randomized Design of six replications. Increasing the proportion of Zn methionine in the mixtures elevated feed consumption, and the highest feed intake was observed in goats received 75% Zn-methionine/25% ZnO. Daily body weight gains was only affected (P<0.05) by the 75% Zn-methionine/25% ZnO supplement. The concentration of Zn in the blood increased significantly (P<0.05) when Zn methionine was added and it increased steadily as the proportion of Zn methionine greater in the mixtures, but the VFA compositions of the rumen were not affected (P>0.05) by Zn supplementation. It is concluded that the performances of goat fed complete diets based on the oil palm fronds could be improved by supplementation of inorganic and organic Zn mixture.
