  Vegetable waste is part from vegetables or vegetables that are not used or discarded in the market. The weakness of this vegetable waste is easy to decay, voluminous (bulky) and the availability was fluctuated, so the processing technology is needed to make this vegetable waste to be durable, easy to stored and easy to given to the animal. To solve this problem is making vegetable waste into wafer feed. The aim of this experiment was to determine the productivity of sheeps that were given by vegetable waste as wafer feed. Experimental design used randomized block design with 5 treatments and 3 replications. The treatments were wafer feed composition i.e R1 (100% of conventional feed), R2 (75% of conventional feed+25% of wafer feed), R3 (50% of conventional feed+50% of wafer feed), R4 (25% of conventional feed+75% of wafer feed), R5 (100% of wafer feed). Conventional feed were field grass and rice bran. The results of this research indicated that the treatments had not significant effect (p>0.05) on productivity of sheep. Sheep were fed by conventional fed had final body weight 27.07 kg, meanwhile sheep were fed 100% of wafer feed complete had 34 kg or 25.6% higher than conventional.

  Livestock productivity required a variety of factors, one of which is the quality of feed. Limitation of livestock productivity in several area in Indonesia are low quality of feed, restricted of forage, especially, in dry seasson. A feed processing technology that might be addopted by to farmers the feed of wafers. Feed wafer processing technology is easy and cheap and can be used to treat these wastes into durable feed, easily to stored and easily given to livestock. Supplementation level in 5, 10 and 15% of wafer and without supplementation was observed in this research. The average daily weight gain by giving 10% of wafer feed supplement to pasundan calves is 58% most highest than other treatment. Final body weight of local calves by giving 10% of wafer supplement most higest than other treatment, the final body weight by giving 10% of wafer supplement around 14% higher than giving conventional feed only. Giving wafer feed supplements did not affect the physiological condition of the cattle based on haematology of blood.

  The objective of this study was to apply effect of Morinda citrifolia L. citrifolia L. leaf extract as antibacterial of Salmonella typhimurium on mortality of Day Old Quail (DOQ), egg production and Hen day, hatchability of layer quail. This research was conducted at Laboratory of microbiology and laboratory of poultry nutrition, faculty of animal science, bogor agricultural university and slamet quail farms cilangkap, sukabumi, west java, Indonesia on March-July 2012. Two hundred and forty heads of quail were randomly assigned to four dietary treatments (sixty heads of quail/ treatment). Experimental design used was Completely Randomized Design (CRD). The treatments consist of level of biscuit Morinda citrifolia L. Citrifolia L. leaf extract i.e R1 = 0%, R2 = 5%, R3 = 10%, R4 = 15%. The results indicated the treatments had significant effect (p<0.05) on mortality of Day Old Quail (DOQ). The average mortality of Day Old Quail (DOQ) was given extract Morinda citrifolia L. leaf were R1 (4.00%), R2 (1.00%), R3 (1.33%), R4 (0.67%). The average mortality of Day Old Quail (DOQ) was given 15% extract Morinda citrifolia L. leaf (R4) was lowest than control treatment (R1). The results of the analysis indicated that Morinda citrifolia L. leaf of quail drink had not significant effect (p>0.05) on egg production, hen day and hatchability. It was concluded that the Morinda citrifolia L. leaf extract 15% can reduce mortality of Day Old Quail (DOQ) and can increase its egg production, hen day and hatchability.
