The aim of this study was to assess the impact and efficiency of red betel leaf’s extract supplementation in the diet of dairy cattle on fermentation characteristics by in vitro. The research method was experiment by using completely randomized design. The treatments that were tested were R1: basal feed, R2: R1 + 15 ppm of red betel leaf (Piper crocatum) extract, R3: R1 + 30 ppm of red betel leaf (Piper crocatum) extract, R4: R1 + 45 ppm of red betel leaf (Piper crocatum) extract, R5: R1 + 60 ppm of red betel leaf (Piper crocatum) extract. The parameters measured in this study were (1)Dry MatterDigestibility (DMD),(2)Organic Matter Digestibility (OMD) (3) total gas production (4) methane production (CH4) and (5) total Volatille Fatty Acid (VFA). The data were analyzed using analysis of variance followed Orthogonal Polynomial Test.The results showed that the suplementation red batel extract in the diet of dairy cow was significant (P < 0.01) on DMD, OMD, total gas production, methane production (CH4) and total VFA.Orthogonal Polynomial test showed the effect of treatment on Dry MatterDigestibility (DMD), total gas and CH4 gas production were in the form of cubic curve, as well as Organic Matter Digestibility (OMD) and Volatille Fatty Acid (VFA) in the form of quadrate curvewith supplementation of red betel leaf.

Field grass is a source of ruminant forage, especially for rural farmers in West Java in different altitudes. The aim of this study was to determine the potential of grass during the dry season including botanical composition analysis and chemical analysis of nutritional value. The study was conducted from September to November 2015 in survey method with multistage sampling. The parameters measured were botanical composition of the forage, biomass production of feed materials on fresh and dry matter, dry matter content, an inorganic matter including calcium and phosphorus, protein, crude fiber and nitrogen free extract. The results concluded for West Java in the dry season that the nutrient content of dry matter and P in lowlands, medium and highland was similar. Crude protein, NFE and TDN at high altitude had higher percentage compared to medium and lowland but crude fiber at high altitude was lower than lowland. Ca at high altitude had higher percentage compared to medium altitude.

The study was aimed at evaluating the performance indices and physiological changes in pearl guinea fowls (Numida meleagris) supplemented with molasses through drinking water. A total of thirty-two (n=32) day-old pearl guinea fowls raised to 12-week-old were used for the study. The fowls were randomly allocated to two groups (control and experimental) of 16 fowls each, with each having two replicates. Experimental fowls were given 5 mL molasses per liter of drinking water for 8 weeks, while control fowls were given only drinking water. Performance indices which include: feed consumption, water intake and percentage weight gain were measured. Rectal temperature was measured and blood samples were collected to evaluate the changes in haematological parameters, serum triiodo thyronine (T3) and thyroxine (T4) concentrations. Results revealed that the molasses-treated fowls had significantly (P<0.05) higher percentage weight gain, blood total protein, packed cell volume and mean corpuscular volume compared to control. However, the feed consumption was significantly lower (P<0.05) in the molasses-treated fowls compared to control. In both groups, rectal temperature increased significantly (P<0.05) during the afternoon hours and was lower (P<0.05) in molasses-treated fowls than control during the evening hours. There was no significant difference in other haematological parameters, serum glucose,T4 and T3betweengroups.In conclusion, molasses supplementation decreased feed consumption, improved body weight gain and enhanced nutritional status and erythropoiesis in guinea fowls.

The objectives of this research were to 1) observe the age, education, farm parents’ cattle ownership, parents’ income, children’s perception and willingness for farming succession, and 2) investigate the relationship between age, education, farm parents’ cattle ownership, parents’ income, children’s perception of and willingness for farming succession. Purposive sampling was used to determine the regional sample in three districts in Banyumas regency with the most dairy cow population and included in the supervised area subject to “Pesat” Milk Cooperative, namely Pekuncen, Cilongok and Baturaden districts. Ninety respondents from 10-30 years old were determined. Result showed that farmers’ children had better education than the parents with average age of 21,67 years old. Average cattle ownership was 1-15 heads per household with Rp 564,167 – Rp 4,523,333 monthly income. Farmers’ children shaped positive perception on dairy farming and had willingness for farming succession. Age was positively correlated with farming perception and willingness of the farmers’ children, while education was negatively correlated.
