Abstract

The preliminary research had been conducted to gather information on nutritive values of various plants such as kayu jawa (Lannea coramandelica), mengkudu (Morinda citrifolia), and kelor (Moringa oleifera) to be used as alternative feeds for ruminant. It was expected that the research could generate recommendation for the suitability of those plants as the sources of ruminant ration, new research plan on the comprehensive nutritive values of the plants, and agronomic tests and their procedure in dry land farming systems. Three replicates of leave samples of 3 development phases (old leaves, well developed leaves, and young leaves along with branches) were taken from the three plant species. Therefore, the number of samples was 27. An Atomic Absorption Spectrophotometer was employed to analyze proxymat and mineral (Ca and P) content of the leaves. The research result showed that : (a) there was no interaction effect between the plant species and the leave development, (b) the content of all leave nutrients were affected by the plant species except that of fat, whereas the leave development significantly affected only the Calcium content, (c) based on the leave nutrient composition contained, M. oleifera and M. citrifolia could be used as alternative feed particularly for calcium and phosphorous supplies for ruminant in the Palu Valley to replace L. coramandelica which have been more popular, (d) As M. citrifolia and M. oleifera contained sufficiently high BETN level, these plants can be used as an alternative feed that can be mixed with other types of feeds containing non protein nitrogen (NPN), thus enhancing the overall feed nutrition. The research recommend that there is a need to proceed the research on L. coramandelica, M. citrifolia, dan M. oleifera as the source of feed for ruminant in the aspect of biological tests such as preferency and digestibitlity either in-sacco or in-vivo. New experiments relating to growth measurements, productive and reproductive levels will comprehensively add the biological values of the three plants as the sources of ruminant feed.

Abstract

The aim of the experiment was to determine spermatozoa fertility and accurate interval time of artificial insemination for improving chicken quality and production. The experiment was conducted using a completely randomized design with three levels of semen diluter as the treatments. Each treatment was tested to 10 local female chicks. The research results showed that the treatments significantly affected the fertility of spermatozoa (P < 0.05). The highest fertility of spermatozoa was found in the ringer lactate diluter (74.73 %), followed by the ringer dextrose (71.58 %), and physiological NaCl 0.9 % (65.79 %). The highest fertility period produced by ringer dextrose diluter was 15.6 days, and ringer lactate for 15.3 days.

Abstract

Sheep is one of the preeminent commodities of Central Sulawesi in term of natural/pastural resources, climatic and cultural social condition. All varieties of local sheep in Central Sulawesi were generated from a cross-breeding between Fat-tail sheep (FTS) and Merbas sheep. The research was aimed at identifying the sheep phenotype characteristics as the criteria for sheep selection. The study was carried out in Palu city, and Biromaru sub district of Central Sulawesi from February to May and from November to December 2006. Data of sheep body sizes were collected from three different sites: Poboya (East Palu), Kawatuna (South Palu) and Loru (Biromaru). A total number of 412 sheep from the three sites were used and then randomly selected to obtain 102 (24%), 122 (10%), and 56 (28%) adult sheep from Poboya, Kawatuna and Loru, respectively. The research results showed that the local sheep population has been steadily decreased every year and currently there have been only 3270 sheep remained. Among the three sites, the highest body weight of sheep was found with those from Biromaru. The average of birth weight, weaning, adult males and females body were 3.25±0.53 kg, 11.25±3.33 kg, 42.00±6.245 kg, and 30.14±6.28 kg, respectively. The body size of 18-24 month old sheep from Biromaru was also higher than those from the other sites. Whereas for 36 month old sheep, those from East Palu and Biromaru were higher than those from South Palu. The principal Component Analysis (PCA) showed that the best criteria for sheep selection were breast diameter, body length, height of hip, and wide of tail.

Abstract

Evaluation of metabolically energy of three agricultural by-products has been conducted on laying hens. The purpose of study was to calculate and to compare the energy values of onion hay, tofu waste and bananas skin. Twelve laying hens were randomly allocated to one out of three types of feeds. About 50 g of powder form of feeds were forced fed to the experimental hens. The results indicate that the gross energy varied within the tested feeds. The highest values of apparent metabolically energy (AME) and true metabolically energy (TME) were achieved by tofu waste, while the energy (AME and TME) values of onion hay were higher than those values in bananas skin. The values of TME were 10.04, 11.88 and 9.58 MJ/kg for onion hay, tofu waste and bananas skin, respectively. It is concluded that the by-product feeds are still having metabolically energy as feeds sources for raising chickens, particularly laying hen
