Cassava leaves as a source of high protein for ruminants and high potential was necessary to be explored as a feed. The cassava leaves was suitable for farmers because its availability was quite a ...lot, especially during cassava harvest. The purpose of this study was to determine the content of cassava leaf substances grown at various altitudes in the West Java. The study was conducted from May to June, 2016. Determination of area (village) was based on the number of cattle in the area. The sampling was done in stages (multistage sampling) to get secondary data. Selected villages were taken six times sample on each height (low, medium and high). The variables measured in this study were dry matter, crude protein, crude fat, crude fiber, calcium, phosphorus and TDN (Total Digestible Nutrient) derived from cassava leaf. The method used was experimental with Completed randomized design (CRD). The results showed that the content of dry matter, crude fiber and phosphorus in the highlands was greater than the medium and low plains. Crude Protein, Calcium and TDN showed the same value at various altitudes. Crude fats in the highlands and medium produce were the same but were higher than in the lowlands.
This study aims to determine the digestibility and fermentability of mineral-fungal combinations. The benefit of this study was to obtain data from the digestibility and fermentability of ...mineral-fungi combinations. The study was carried out in vitro with a completely randomized factorial 2 × 4 design with 3 replications. The variables observed were dry matter digestibility, organic matter digestibility, total VFA production (total volatile fatty acid), and NH3. The data obtained were then analyzed using variance test (ANOVA), if there was an influence on the variables measured, it will be followed by the Tukey’s Studentized Range test. The results showed that the combination of minerals gave a significant effect (P <0.05) and there was an interaction between mineral-fungi (P <0.05) in the digestibility of organic matter and VFA. The highest result was combination mineral with S. cerevisiae and as individual was combination Cu-Sc and Se-Sc. Keywords: Digestibility, Fermentability, Fungi, Mineral, Rumen.
One hundred twenty-five female ducks, with an average body weight of 1485.51±14.72 g, aged eight weeks, were used in this experiment to examine the effect of ginger volatile oil (GVO) on the ...metabolic profile of the glycolytic pathways, free radical and antioxidant activity in heat-stressed Cihateup ducks. GVO isolation was carried out by the distillation technique. Cihateup duck samples were divided into five treatment groups, each group with 25 animals. Each treatment consisted of five replications so that each repetition consisted of 5 duck samples. The treatment in this study was A: temperature of the comfort zone (24°C) and without administration of GVO; B: heat stress (38°C) and without GVO; C: heat stress (38°C) and 150 µL GVO/tail; D: hot stress (38°C) and 200 µL GVO/tail, E: Hot stress (38°C) and 250 µL GVO/tail. GVO was given every morning orally (force-fed). The data then statistically analyzed with ANOVA procedure to determine the treatment effect. Duncan's multiple range test was used to compare the treatment effect. The results showed that the metabolic profile of the glycolytic pathway appeared to be in the normal range by administering 250 µL GVO. The reduction of free radicals activity and increased endogenous antioxidants (Glutathione Peroxidase) activity were also found in GVE treated ducks. In conclusion, the heat stress of Cihateup duck was reduced by administering the GVO.
Feeding management is a very important factor that makes sure fulfil quality and quantity for livestock nutrient sufficiency that affects the success rate in livestock farming. The excellent macro ...nutrient needs determination is an absolute thing to achieve the optimal growth which represented by digestibility and average daily gain. Feed formulation that considering the material selection, availability, and the price of feed materials could gave sustainable livestock feed management. The study was carried out to evaluate the effect of macronutrients needs on digestibility and average daily gain of sheep. Twenty Padjadjaran sheep (Ovisaries var. Padjadjaran, Family Bovidae), which resulted from crossbreeding between South-African Capstaad, Merino, and local, were chosen as tested animals. These white sheep were placed separately in individual metabolism cages. All animals were 8-10 months of age and their body weights ranged between 15-33 kg. The animals were divided into 5 groups and each group was treated with different dietary feeds (4 times replication) that contained dry material, crude protein, crude fiber, crude fat, and nitrogen-free extract (NFE). The parameters measured were dry matter intake (DMI), dry matter digestibility (DMD), organic matter digestibility (OMD) and average daily gain (ADG). The treatments showed no significant effect on DMI, DMD, and OMD, whereas an increase of ADG (113.33 - 169.17 g/animal/day) was observed on all animals. One of R2-treated animal showed an increase of 276.67 g/day.
Palm oil fiber has its potency as feed fiber source for ruminant, but contains high lignin and causes limited digestibility. This research was carried out to find the effect of soaking palm oil fiber ...in filtrated palm oil fruit bunch ash (FPOFBA) on in vitro digestibility. This experiment used a completely randomized design that repeated for 4times. Palm oil fruit bunch ash was mixed in water and entered into container for 24 hours within concentrations, consists of: 50, 100, 150 and 200 g/L. Moreover, this filtrate used to soak palm oil fiber for 3 hours. The processed products were analyzed for their level of lignin and crude fiber. Meanwhile, in vitro test was used to measure digestibility. It showed that soaking in filtrated palm oil fruit bunch ash gave significant effect to decrease level of lignin and crude fiber (P<0.05), and without soaking to improve digestibility of dry and organic matter compared to control treatment (P<0.05). Treatment with 150 g/L and 200 g/L using filtrated palm oil fruit bunch ash produced low level of lignin (P<0.05), as of: 17.25 and 18.53%. In contrast, within concentration of 150 g/L produced higher level of crude fiber compared to 200 g/L (46.04 vs. 43.87%). This seemed to have the same results in digestibility of dry and organic matter (P>0.05), such as 23.48 and 24.12% as well as 16.70 and 17.06 % in each. It can be concluded that soaked palm oil fiber with 150 g/L concentration of filtrated palm oil fruit bunch ash was more effective in improving digestibility.
