  This study aims to analyze the effect of biscuit bio-supplement on milk production and quality at dairy goats farm . This research was conducted on June-October 2013 at different dairy goats farm in Bogor, Indonesia.. This research used a factorial completely randomized design 2x2x6 with two treatments and six replications which factor A was level of biscuit bio-supplement (T0 = 0% of biscuits bio-supplement and T1 = 15% of biscuit bio-supplement). Factor B was different location of dairy goat farms (Ciapus farm and Leuwiliang farm). The result indicated that the treatments had significant effect (p<0.05) on milk production and calcium content of milk. By feeding of 15% biscuit bio-supplement had milk production 673 mL head-1 day-1 at Ciapus farm while by feeding without biscuit bio-supplement had milk production 671.99 mL head-1 day-1. By feeding of 15% biscuit bio-supplement had milk production 539.75 mL haed-1 day-1 while by feeding without biscuit bio-supplement had milk production 318.28 mL head-1 day-1 at Leuwiliang farm. By feeding biscuit bio-supplement did not significant effect (p>0.05) on fat, protein and lactose of milk. By feeding 15% biscuit bio-supplement yield milk production 41.03% higher than conventional feed at the farm with using low protein of feed while milk production approximetly only 0.15% higher than conventional feed at the farm with using high protein of feed.

  In Indonesia, Ettawa crossbreed goat is one of common milk goat that categorized low production goat. Bio-supplement biscuit is one of feed industry to increase milk production. This study aims to evaluated milk production and calcium content. The used 10 Ettawa crossbreed in Bangun Karso Farm. Research design used t-test with treatments: T0 = Mix forage+concentrate and T1 = Mix forage+concentrate+biscuit 15%. Parameters were milk production and calcium content. The research resulted that biscuit bio-supplement affected milk production and calcium content significantly (p<0.05). Biscuit bio-supplement contained papaya leaves increased calcium content until 174.832 mg/100 g. Active compounds in papaya leave was proved increases milk production and calcium content. Biscuit bio-supplement increased 43.35% milk production and 48.27% calcium content.

  Sub-sector of livestock has an important role in the life and development of human resources in Indonesia. An important issue on agribusiness beef cattle is a continuous population decline every year. The application of technology has to be initiated in order to obtain production efficiency and production cost efficiency. One of the factors that affect the productivity of livestock is feed. The major constraints of ruminant feed are low quality of forage, the low level of palatability and digestibility. To solve this problem is making forage waste into wafer feed supplement. The aim of this experiment was to determine the nutrient content on wafer feed supplement and productivity of local calf that were given by wafer feed supplement. This research was conducted at Laboratory of Feed Industry, Bogor Agricultural University and the performance test at Karya Anugrah Rumpin Corporation on March-April 2016. To determine the nutrient content of wafer feed supplements used proximate analysis. The experiment of productivity used 12 heads of male local calves (Sumba Ongol calves) with average body weight around 136±22.46 kg with ages around 12-18 months. The experimental local calves were maintained individually. The experimental design used randomized block design with four treatments and three replications. The treatments were feeding patterns of wafer feed supplement i.e., T1 = 0% by feeding wafer supplement+concentrate+king grass, T2 = 10% by feeding wafer supplement+concentrate+king grass, T3 = King grass+10% by feeding wafer supplement+concentrate, T4 = Concentrate+king grass+10% by feeding wafer supplement. The parameters measured were productivity of local calves, i.e., daily weight gain, final body weight, consumption, dry matter and organic matter digestibility, blood cholestrol, blood glucose, blood protein. It was concluded that feeding pattern wafer feed supplement can increase consumption and not influence condition of local calves. It was concluded that daily weight gain by feeding wafer supplement feed 42-45% higer than conventional feed. High crude protein of wafer feed supplement is good supplement for ruminant in the tropic.

  The objective of this study was to apply the physical characteristic and palatability of biscuit bio-supplement for dairy goat. This research was conducted at Laboratory of Feed Industry, Faculty of Animal Science, Bogor Agricultural University, Indonesia and the palatability test was conducted on the dairy goat farm at Leuwiliang, Bogor, Indonesia on March-July 2012. Twenty heads of dairy goat were randomly assigned to five dietary treatments (four heads of goat/treatment). Experimental design used Completely Randomized Design (CRD). The treatments were biscuit bio-supplement composition i.e., R1 = biscuit bio-supplement of Indigofera sp., R2 = biscuit bio-supplement of Sauropus androgynus L. Merr leaf, R3 = biscuit bio-supplement of Carica papaya L. leaf, R4 = biscuit bio-supplement of Sauropus androgynus L. Merr leaf and Indigofera sp., R5 = biscuit bio-supplement of Carica papaya L. leaf and Indigofera sp. The variables measured were moisture, water activity, water absorption, density and palatability of dairy goat. The results of this research indicated that the treatments of biscuit bio-supplement gave significant effect (p<0.05) on water content, water absorption, density and palatability, but had not significant effect on water activity. Palatability of R1 was 76.38±7.92, R2 was 23.81±6.08, R3 was 40.25±3.54, R4 was 29.56±4.77 and R5 was 95.63±7.36 g/head. Biscuit bio-supplement of Carica papaya L. leaf and Indigofera sp., (R5) had the best value of palatability for dairy goat and had the best crude protein (36.65%), also had lowest water activity, highest density than the other biscuits.

  Background and Objectives: Nigella sativa is the scientific name for black cumin or habbatussauda. Nigella sativa seeds contain oil commonly used for medicinal purposes to treat various diseases. Nigella sativa meal (NSM) is a by-product from the industry that extracts the oil. NSM contains a high protein content and can be used as a source of protein in the diet. The purpose of this research was to evaluate the effect of using NSM as a feed on the growth performance, metabolite and blood profile and nutrient digestibility of lambs. Materials and Methods: This study used a randomized block design with 5 replicates of 3 treatments using 15 local Indonesian male lambs. The concentrations of NSM in the rations were 0, 10 and 20%, with a maintenance period of 56 days. The forage to concentrate ratio was 30:70. Results: The average daily weight gain and blood urea nitrogen (BUN) concentration of the experimental animals were significantly (p<0.05) higher for the diets that contained 10 and 20% NSM (T1 and T2) compared to those for all other treatment groups. Additionally, the use of NSM in the diet improved the digestibility of crude protein, nitrogen retention and nitrogen use efficiency, with the mean biological value of protein being higher for the diet that contained NSM T1 (99.51) and T2 (99.44) compared to that for the control treatment group T0 (98.09). Conclusion: When the concentration of NSM reaches 20% in lamb rations, it has the most effect on growth performance and nutrient efficiency without affecting the metabolite and blood profiles, which remain in the normal range.

  Background and Objective: Piper betle L. leaves (beetle leaves) is an example among medicinal plants that could inhibit the growth of Salmonella. This research was aimed to evaluate beetle leaves aqueous extracts ability to inhibit Salmonella sp. by in vivo and in vitro research. Materials and Methods: The research was consisted of three steps. Those steps were finding optimum concentration of extract supplementation, raising the quails and evaluating Salmonella sp. colonies in small intestine of quails which had been given treatment for six weeks. A completely randomized design of seven treatments and three replication was used in this study. The treatments were: P0 = commercial anti-stress supplementation since Day Old Quail (DOQ); P1 = 10% extract supplementation since DOQ; P2 = 20% extract supplementation since DOQ; P3 = 30% extract since DOQ; P4 = 40% extract supplementation since laying period; P5 = 10% extract supplementation since laying period; P6 = 20% extract supplementation since laying period; P7 = 30% extract supplementation since laying period. Data was analyzed with Duncan post hoc test if shows a significant difference (p<0.05) using SPSS as statistical analysis software. Results: According to the inhibition zone, the results show that right level supplementation of extracts to be used was 10% (2.5 mm), 20% (3.5 mm) and 30% (7 mm) which had been added in drinking water. Compared to control treatment (P0), addition of extracts (P1, P2, P3, P4, P5 and P6) could decrease the colonies of Salmonella sp. in small intestine of quail significantly (p<0.05). Conclusion: Beetle leaves aqueous extract supplementation could inhibit Salmonella contamination. Higher concentration of extract leads to higher inhibition zone. The best treatment to reduce Salmonella sp. was P6. Extracts supplementation are better given at laying period rather than DOQ period.
