Two experiments were conducted to evaluate nutritional value of putak for broilers. Experiment 1. The apparent metabolisable energy of raw and fermented putak were determined. The experimental design used was completely randomized design with three treatments and four replicates. Total of 64 broilers were randomly distributed to 16 pens. A maize-soybean meal basal diet was formulated and three assay diets were then developed by substituting putak (raw, and fermented, 250 g kg-1, w/w), and maize (500 g kg-1, w/w) of the basal diet. Even though the AME and AMEn values of fermented putak were comparable to that of raw putak and maize, but it was slightly higher than that of raw putak. Experiment 2. Using the AME value of raw putak obtained in Experiment 1, five treatment diets containing 0 to 200 g kg-1 putak were formulated. The body weight gain of broilers fed 150 - 200 g kg-1-1 putak was higher to that of control diet, but it was similar to those fed 50-100 g kg-1 putak. No differences were found in FCR and mortality rate. Feed intake of broilers fed diets containing putak was higher than that of control diet. In conclusion, the AME and AMEn values of putak, fermented putak, and maize were comparable. Putak can be included in broiler diets up to 200 g kg-1 without detrimental effects.

Background and Aim: Horses have a strategic and vital role to play in the lives of the people of Sumba Island, East Nusa Tenggara Province. They act as social animals that are involved in death ceremonies, horse races, and during pasola, thereby supporting tourism, and are given away as dowry in wedding ceremonies. This study aimed to investigate the prevalence of trypanosomiasis among horses in four districts of Sumba Island by examining clinical symptoms and detecting parasites, antibodies, and other factors that are related to Trypanosoma evansi infection in horses. Materials and Methods: We studied a total of 211 horses that belonged to 88 clinical hobby breeders. Giemsa-colored smears and serum were examined in order to detect antibodies using card-agglutination tests (CATT). The study was conducted during the rainy season that lasted from January to March 2017. Potential risk factors such as the species, sex, origin of the livestock, how the livestock were maintained, and the farmers' knowledge concerning trypanosomiasis were recorded using questionnaires. Data were collected annually for three years from 2010-2012 and repeatedly analyzed by a Chi-square test. Results: Clinical signs of trypanosomiasis were found in 34 horses; blood smears were examined using Giemsa staining and negative preparations were obtained at a frequency of 0.0% (0/211). The CATT results generally showed that 13.3% (28/211) of the samples were seropositive for antibodies to T. evansi; the highest percentage, 16.67% (8/48), of seropositivity was found in the West Sumba District, and the lowest, 12.0% (5/50), was found in Southwest Sumba. The incidence of trypanosomiasis was higher (75% [21/28]) among female hip horses; horses with 1-5 years of experience were more susceptible to a T. evansi infection (46.4% [13/28]). In general, farmers on Sumba Island knew of trypanosomiasis (89.8% [79/88]), and 69.3% (61/88) of the farmers reported that their livestock was sick. This study was the first serological study conducted on trypanosomiasis in horses of Sumba Island after the surra outbreak in 2010-2012. There were 3% of farmers who were willing to provide the government with information on implementing a prevention program and controlling the spread of surra on the island. Conclusion: The diagnoses of surra disease were made based on clinical symptoms and parasitological examinations. CATTs could be used to diagnose T. evansi infection in horses.

High energy diet is related to high feed cost. Thus, it is essential to reduce energy diet but still support the good performance of birds. The utilization of low cost- feed ingredients combined with enzymes are the alternative way to do. The objective of this study was to investigate the effects of multy-enzyme supplementation on growth performance of broilers fed low energy basal diets containing rice bran. Experiment 1. The apparent metabolizable energy (AME) assay of yellow corn and rice bran. A total of 48 broilers were randomly distributed to 12 cages (4 birds/cage). A maize-soybean meal basal diet (mash form) was formulated and two assay diets were then developed by substituting rice bran (raw 250 g kg-1, w/w) and maize (500 g kg-1, w/w) of the basal diet. Total excreta collection method was used. The results showed that the AME value of rice bran was significantly lower (2032 kcal/kg DM) and 3112 Kcal/kg DM. Experiment II. The experiment was designed using a completely randomized design with four treatments and six replications. A total of 160 DOC (unsex) were randomly distributed to 16 pens (10 birds/pen). The experimental diets were iso-nitrogenous and iso-energetics. The results show that dietary treatments significantly affected (P0.05) FCR and mortality of broilers. Broilers fed P2, P3 and P4 diets had higher (P0.05). In conclusion, 1) the supplementation of enzymes in low energy diets containing rice bran improved BWG and FI but not FCR and mortality. 2) Birds fed rice bran-containing-diets supplemented with enzymes produced similar growth performance.

The long term objective of this activity is to improve the income of farmers (partner) in Dusun Binilaka, Oeltua Village, Kecamatan Taebenu District, Kupang Regency, East Nusa Tenggara. The special target is to improve the production performance of pigs and cows of farmers the implementation of feed technology, housing by product processing. Method used is survay, extension, and plot demonstration. This activity is expected to contribute to the implementation of feed technology to improve animal performance and to solve feed shortage in dry season in and to reduce feed cost.
