Abstract

Zeolite is a composite minerals from mining which can be used as a source of minerals in animal ration. It has high absorbability and cation exchange characteristics. This study was aimed to examine the influence of zeolit and blood meal in the pig ration on pork quality characterictics. The experiment used 27 crossbred pig comprising 19 gilts and 8 barrows, with initial weight of 25.29 + 2.67 kgs. They were set up in a completely randomized factorial design 3 x 3, where the first factor was zeolit levels (0, 3, and 6%) and the second factor was blood meal level (0, 5, and 10%). The results showed that there were no significant influence of zeolite, blood meal or their interaction on all meat quality characteristics including pH, water holding capacity, tenderness, color and intramuscular fat contents of pork, except the measurement at pH of six hours postmortem of the pork was significantly (P < 0.01) affected by blood meal level of the ration. Five percent (5%) blood meal in the ration gave the highest pH of pork compared to the other blood meal levels. Key words: pig, pork quality, zeolite, blood meal

Abstract

This research was conducted to evaluate the effect of corn gluten feed as corn substitution in the rations on swine carcass quality and economic analysis. The rations consisted of different levels of corn gluten feed (0%, 20%, 35% and 50%) as corn substitution. The portion of corn was 30% in grower ration and 25% in finisher ration. A completely randomized design was used in this research. Slaughtered weight, carcass weight, carcass percentage, carcass length, backfat thickness and loin eye area were observed. The data were analyzed by analysis of variance. The results showed that corn gluten feed did not significantly affect all parameters of carcass quality. Economic analysis showed that the use of corn gluten feed as corn substitution on swine rations produced lower profit. Key words : corn gluten feed, carcass quality, swine

Abstract

The optimal storage temperature for preserve boar semen is 17-18°C. The temperature fluctuations can decrease sperm viability. The aim of this study was to obtain a boar semen extender for Artificial Insemination (AI) at a certain distance area. The observation was based on the sperm viability in modified Beltsville Thawing Solution (BTS) extender in different storage, and the effect of storage system i.e.: room temperature (22°C) and styrofoam box (18°C) were conducted for this purpose. The research used a completely randomized design (CRD) with two factorial i.e.: BTS and M-BTS extender (F1), room temperature and styrofoam box (F2). Semen from three years old Yorkshire boars (n = 3) were collected twice a week by glove hand method. Semen characteristics and their quality were evaluated macro and microscopically. These semen were added with BTS and M-BTS extender up to fourfold volume (ratio 1 : 3). This is based on the assumption of AI dose of 2 - 3 x 109cells/80ml and the sperm motility and viability were evaluated every six hours for 24 hours observation. The results showed that fresh semen characteristics were good, with the percentage of sperm motility 65.56±2.55% and sperm viability of 87.70±2.87%. The best extender found in this experiment of 24 hours observation was BTS extender with sperm motility 53.33±3.33% in styrofoam box. In conclusion, BTS extender can maintain the quality of spermatozoa stored in styrofoam box for about 24 hours with sperm motility 40%-50%, and the styrofoam box can be used as an alternative container for insemination program in the field. Key words: sperm viability, semen extender, storage, boar sperm
