Abstract

Abstract.There seach objective was to determine the productivity and nutrient content of Paspalumconjugatum, Brachiariadecumbens, Digitariamilanjiana by buffalo fermented compost. The research was conducted at the Goat Farm Research Station SeiPutih, SubdistrictGalang, LubukPakam, North Sumatra from October 2015 through February 2016. The design used was split plot design (plots divided) with mainplotwas kind of grass A1 (Paspalumconjugatum), A2 (Brachiariadecumbens), A3 (Digitariamilanjiana) and the subplot was fertilizer dose as the level (0, 10, 20 and 30 t/ha/y). The parameters studied were production of fresh, high plant, number of tillers, dry matter, crude protein, and crude fiber. The results showed that administration of buffalo fermented compost better than without the use of fertilizers. Dosing compost  significant affect (P<0.05) in increasing production of fresh, high plant, number of tillers, dry matter, crude protein and crude fiber. The conclusion of this study that the  best dose was 30 t/ha/y of  buffalo fermented compost  and the best interactions was dose of 30 ton/ha/year on Digitariamilanjiana. Keywords: Paspalumconjugatum, Brachiariadecumbens, Digitariamilanjiana, buffalo fermented compost, dose, kind of grass

Abstract

Abstract.This research objectives to investigate the distance of genetics and differentiator factor of the horses in four District in North Sumatra. This research was conducted in Karo District (60 heads), Humbahas District (77 heads), Tapanuli Utara District (52 heads) and Samosir District (42 heads) at July 2016. The analysis used  were descriptive analysis, discriminant analysis, canonical analysis, principal component analysis, genetic distances and filogenic tree. The observed variables in this study were shoulder height, hip height, hip width, body length, chest circumference, chest and chest width, and the variables that distinguish the horse in term of size were hip height and in terms of shape was the width of the chest. The nearest genetic distance was the horse between Karo and North Tapanuli District (0.869) and the horse that had the farthest genetic distance were horses in Karo District with horses in Samosir District (14.539). Based on the results of morphometric measurements of horses in this study, in order to obtain heterosis, it was expected to cross between horses in Karo District and horse in Samosir District. Keywords: morphometric, discriminant analysis, canonical analysis, principal component analysis, genetic distance

Abstract

This research aimed to conclude the best combination of commercial strain and feed on broiler’s carcass. This research was conducted at Animal Husbandry Biology Laboratory, Departement of Animal Husbandry, Faculty of Agriculture, University of North Sumatera for 4 weeks from November until December 2016. This research used completely randomized design (CRD) factorial with 9 combined treatment and 3 replication. The treatment consists of A0B0, A0B1, A0B2, A1B0, A1B1, A1B2, A2B0, A2B1, A2B2. The observed parameters were cutting weight, carcass weight, and carcass percentage. The result showed that the average weight of broiler chicken ranged from 1829,50 – 1929,50 gram/head. The average of Carcass weight ranged from1424,75 – 1676,50 gram/head. And the average of carcass percentage ranged from 78,01 % - 87,98 %. This research conlude that the best combination is A1 and B0.
