Abstract

Potato cyst nematode (Globodera rostochiensis Woll.) is an important plant pathogen on potatoes. The development of this nematode in soil could be controlled by using soil fungi. In vitro assay to determine the capacity of soil fungi Fusarium oxysporum TR1, F. solani TR2, F. oxysporum KT1, F. chlamydosporum KT2, F. oxysporum SM1, Paecilomyces lilacinus SM3, and F. chlamydosporum SM4 to parasite G. rostochiensis has been cariied out. The results showed that all of tested fungal species enable to reduce the number of living J2 out from the cyst. The highest J2 reduction, 67.48%, was evidence by using P. lilacinus.

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
