Abstract

This study aims to determine the effect of mineral-vitamin complex supplementation in the ration to growth performance boar crossbreed the age of 2-6 months. The design used was a randomized block design (RBD) comprising 3 treatments and 4 groups as replication, clustering based on weight. The treatments were attempted diets without supplementation of mineral-vitamin complex as the control (A), the diets with 0.10% mineral supplementation-vitamin complex (B), and 0.20% diets supplemented mineral-vitamin complex (C). The variables measured were final body weight, weight gain, feed intake and feed conversion ratio. The results showed that supplementation of mineral-vitamin complex at the level of 0.10% and 0.20% (P <0.5) can improve the final body weight, weight gain and feed efficiency in use but not significantly (P> 0.5) increases feed intake in pigs race crosses the age of 2-6 months. It was concluded that supplementation of 0.10 to 0.20% mineral-complex vitamins in the ration can increase the final body weight, weight gain and feed efficiency in the use of the boar cross breed.

Abstract

The purpose of this study is to determine the population of nitrogen-binding bacteria to bahia grass (Paspalum notatum Cv. Competidor) rhizosphere with various level of nitrogen, phosphor, and calcium fertilizer. The study was conducted for 15 weeks. The design used was Completely Randomized Design with three replicates and ten treatments so that there were 30 pots and soil samples with various level of N, P, and Ca fertilizer combinations, i.e., without fertilization or control, 100; 150; 200 kg/ha N, 50; 100 kg/ha P, and 50; 100 kg/ha Ca combined with prescribed treatment. The variables observed were TPC, total N fixing bacteria, nitrogen content, root dry weight, and root volume. According to the results of this research showed that in P0 treatment for TPC and total N fixing bacteria with an average of 5.27 x 106 cfu / g and 4.07 x 106 cfu / g have the most bacteria involved, so does for N content in P0 treatment with an average of 0.14 ppm is giving the highest N of value. Variable characteristics of the growth of Pasmalum notatum Cv. Competidor grass respectively have optimal results on treatment N150 P50 Ca50, among others, dry weight of kroots with an average of 3.50 g, root length with an average of 88.37 cm and root volume with an average of 15.93 g. Based on this research, it could be conclude that increasing in distribution of N fertilizer will reduce the total activity of bacteria population and the total population of N binding bacteria, however, the distribution of N fertilizer could be regenerate by distribution of P and Ca fertilizer. The N volume will lower in the combination of N, P and Ca fertilizers compared with no fertilization. The best growth characteristics of bahia grass will be gain by using N150 P50 Ca50 fertilizer.

Abstract

This study aims to obtain information about the influence of the length of defoliation on growth and grass production. The study was carried out in the green house of the Faculty of Animal Science, Udayana University for 10 weeks. The design used was a completely randomized design (CRD) pattern of split plot, main plot / species of grass and sub plot / sub plot long defoliation with replications four times so that there were 48 experimental units. The grass used is three species of local grass were Axonopuss compressus, Stenotaphrum sucundatum and Paspalum conjugatum. With treatment D1 = 5 cm defoliation treatment, D2 = 10 cm defoliation, D3 = 15 cm defoliation and D4 = 20 cm defoliation. The variables observed were plant length, number of leaves, number of tillers, leaf dry weight, stem dry weight, root dry weight, total dry weight of leaves, ratio of leaf dry weight to stem dry weight, ratio of total forage dry weight to root dry weight and broad leaves per pot. The results showed that plant species were significantly different in plant length variables, number of tillers, leaf dry weight, stem dry weight, total dry weight of forage and leaf area. The results of the defoliation length were significantly different in the plant length variable, number of leaves and dry weight of the stem. Based on the results of the study it can be concluded that D4 defoliation = 20 cm tends to give a positive response and Paspalum conjugatum grass gives the highest growth and production response and there is no interaction between the length of defoliation and the type of grass. Key words: local grass, defoliation, growth, production
