Publisher : Fakultas Peternakan, Universitas Hasanuddin, Makassar

The objectives of this experiment were to determine dry matter yield and competitiveness of alang-alang (Imperata cylindrica) and guinea grass (Panicum maximum) in intercropping. The experiment was arranged in factorial combinations of four planting proportions, two levels of nitrogen fertilization and three harvesting intervals with three replications. Planting proportions were 0, 33.3, 66.7, and 100% of alang-alang (planting densities of 0, 1, 2 and 3 plants/pot) combined with 100, 66.7, 33.3, and 0% of guinea grass (planting densities of 3, 2, 1 and 0 plants/pot). The plants fertilized with nitrogen fertilizer at the doses of 0 and 250 kg/ha and harvested at intervals of 30, 45 and 90 days. Results of experiment showed that as planting proportion of alang-alang increased in the mixtures, total dry matter yield of mixed plants decreased. N fertilization increased dry matter yield in both species, but guinea grass was more responsive than alang-alang. Regardless of planting proportion and nitrogen fertilization, increasing harvest interval decreased dry matter yield of guinea grass – alang-alang mixture. Intercropping system gave substantially higher yield advantage over sole cropping in terms of land equivalent ratio with the maximum value achieved when guinea grass – alang-alang mixture planted at the ratio of 2 : 1, fertilized with N and harvest monthly. In intercropping system, guinea grass appeared to be the dominant crop as indicated by its higher values of relative crowding coefficient and positive sign of aggressivity index. It reflects that guinea grass grown in association with alang-alang utilized the resources more aggressively than when alang-alang grown alone.

Publisher : Fakultas Peternakan, Universitas Hasanuddin, Makassar

The research was conducted to evaluate the effect of addition of tannin, saponin or combination of tannin and saponin to the concentrate of the ration on the microbial population and fermentability of feed in vitro and to assess the best dosage of uses. The research was arranged according to completely randomized design with four treatments and 3 replications. The treatments were ration without tannin and saponin (T0), ration with 1.2% saponin (T1), ration with 0.5% tannin and 0.9% saponin (T2), ration with 1% tannin and 0.6% saponin, (T3), ration with 1.5% tannin and saponin 0.3% (T4) and ration with 2% tannin and 0% saponin. the results of the experiment showed that the addition of the tannin, saponin or their combination altered microbial population in the rumen. Protozoas population decreased significantly whereas bacterial population was increased. NH3 production increased while ratio of acetaic to propionic acid tended to decrease. Total gas production increased 62.59-69.35 ml/200 mg of dry matter. The addition of 1% tannin and 0.6 % saponin shows the best effect to control protozoa population and feed fermentability in the rumen.

Publisher : Fakultas Peternakan, Universitas Hasanuddin, Makassar

Katuk (Sauropus androgynus (L) Merr) is belonged to the Family of Euphorbiacea. It is a herb plant with 2-3 m height. It is a tropical plant having many benefits for livestock productivity including for poultry production. The experiment was carried out according to completely randomized design. The number of cages used in this study was nine, in which the size of each cage was 1 m x 0.5 m. Three chickens were placed randomly in each cage. Once a week, the measurement for egg weight was conducted for the whole egg, including yolk weight, eggshell weight, yolk color intensity. All measured data were calculated for getting the average value. At the last week of the experiment (on the 55th week), samples were randomly taken from each treatment. The findings of research showed that adding 15% of katuk leaves meal into the laying ration resulted in positive effects on carcass and egg quality, indicated by an increase in egg yolk weight and vitamin A and a decrease in egg yolk cholesterol up to 16.82%. The content of estradiol hormone of the egg increased following the increase level of katuk leaves meal in the ration

Farmers’ participation in agricultural extension can improve the relevancy between extension services and the farmer needs. There are many factors that may affect farmers’ participation in agricultural extension. The aim of this study was to understand characteristic influence and perception of farmers onto extension towards level of farmer participation in agricultural extension. Method applied was non experimental design survey with structural equation model analysis and analysed using Lisrel 8,3 application. The number samples were which were obtained from two areas, 103 that divided by two area, central area 57 samples and non central area 46 samples. Exogenous variable was farmers’ characteristics and endogenous variable were farmers’ perception and level of farmers’ participation in agricultural extension. The analysis of structural model indicated that farmers’ characteristics negatively correlated with farmers’ perception to agricultural extension in which the higher levels of age, cosmopolite, and formal education. Similarly, farmers’characteristics negatively affected either directly or indrectly farmer participation, meaning the the higher levels of age, formal education, and cosmopolite the lower participation level on the extension. Effects of perception on participation was significantly negative, indicating that the higher perception the higher participation in the extension. Quality of extension services e.g. extension materials, method used, and capacity of extension officers must be improved. Current extension services can only meet the needs of young farmers. The more complex the farmers’ needs the more unlikely the extension to meet famers’ needs.

Feedstuff availability is one of the problems in the poultry meat production system, which uses corn as the main energy source in the ration. One of the alternative solutions is to identify the feedstuff that has potential, qualitative and quantitative, to substitute it. Banana tuber contains high carbohydrate and low fiber components so that it can be used as energy source in the ration. The aim of research was to compare the benefit between the ration containing banana tuber meals, which was provided from batu and kapok banana tuber, and the commercial broiler ration. One hundred and ninety two of broiler chicks were raised for 30 days and were randomly allotted to one of four treatment diets according to completely randomized design with four replications for each treatment. The experimental rations were P0 (control, 100%of commercial feed), P1 (60% of commercial feed + 30% of banana tuber meal + 10% fish meal), P2 (70% of commercial feed + 20% of banana tuber meal + 10% fish meal), and P3 (80% of commercial feed + 10% of banana tuber meal + 10% fish meal).The results of the study indicated that the average body weight gain was 58.75, 54.65, 51.95, and 48.68 g/d for the treatment P0, P1, P2, and P3, respectively. In conclusion, the use of 30% banana tuber meals in the commercial feed mixtures does not deteriorate the performance (daily gain) of the broiler.

The study was conducted to evaluate intercropping forage production between inoculated arbila (Phaseolus lunatus) and sorghum (Sorghum bicolor) at different planting space of arbila and different row number of sorgum. The experiment was arranged factorially according to completely randomised design. The first factor was two planting space of arbila i.e. J1 (120 cm) and J2 (180 cm). The second factor was three different row number of sorghum i.e. P1 (1 row), P2 (2 rows), P3 (3 rows). The replication for each treatment combination was three giving total number of experimental units of 18. Variables abserved were organic matter (OM), crude protein (CP), crude fiber (CF), nitrogen free ekstract (NFE), ether extract (EE), and ash contents of intercropped forage. Results showed that nutritional value of intercropping forage between arbila and sorgum was better compared with monoculture crop of either arbila or sorghum. At intercropping, OM content of all treatments were high, except for treatment J1P1. The lowest CF was noticed for treatment J1P2 (30.64%). The highest CP content was for J1P1 (16.16%) but the CP content of J1P2 was still quiet good (13.36%). EE values were relatively similar for all treatments. The highest value for NFE was for J1P3 (48.35%) and J2P1 (48.45%) but the value for J1P2 was still reasonably good (48.35%). The ash content for treatment J1P1, J1P2, and J1P3 was 8.62%, 7.51%, and 7.15% respectively, and it was considered good enough for forage. In conclusion, intercropping between arbila at 120 cm planting space and 2 or 3 rows of sorghums produces the best nutritive content of forage for ruminant feed.

Publisher : Fakultas Peternakan, Universitas Hasanuddin, Makassar

This experiment was conducted in vivo to investigate the effects of feeding WCS as a supplement for sheep fed GH on the apparent feed digestibility, and the rumen fermentation. Four different diets (T1-T4) were used, GH alone, or GH plus 150, 300 or 500 g WCS d-1 (fresh basis). The main objectives of the in vivo experiment was to examine digestibility and rumen characteristics (pH, ammonia and VFA concentration) of sheep fed the four diets. The results of this experiment indicated that supplementation of GH with WCS at level of 500 g d-1 (0.37 of the diet) reduced DM, ADF and NDF digestibility. There was no statistically significant effect on total rumen VFA, but the molar proportions of acetate, propionate and butyrate were altered by the highest rate of inclusion of WCS. These results suggested that WCS might have reduced the numbers or activities of cellulolytic rumen microorganisms.
