This study aimed to determine the effect of homofermentative and heterofermentative lactic acid bacteria on the chemical and nutritional components of corn silage. The variety of corn used in this study was GWG 4546 at the harvesting age of 110 days. It was ensiled with 10⁵ cfu of LAB for each gram of fresh material. The strains of LAB used to ensile were P. acidilactici (homofermentative LAB), L.plantarum (hetero-homofermentative LAB) and L. fermentum (heterofermentative LAB). The fresh stover was packed in 5L of HDPE plastic jar and kept at room temperature for 28 days. The silages were harvested every week for chemical and proximate analysis. The experimental design was completely randomized design, with 5 treatments x 4 fermentative periods x 3 replicates. From the study, inoculation of homofermentative P. acidilactici produces more lactic acid at an early stage of ensiling, whereas heterofermentative L. plantarum produce more lactic acid at later stages. Furthermore, the crude protein content and metabolizable energy of corn stover silage inoculated with homofermetative LAB were found to be constant throughout the 28 days of fermentation and the values were significantly higher than silages in other treatments. However, there were no significant differences in fibre content, ash content, pH values, dry matter, and fat content among all groups. Therefore, it can be concluded that the addition of homofermentative P. acidilactici resulted in better preservation with improved energy and protein values in 110-days of grain corn stover after 28 days of ensilation.

Abstract

This study aimed to determine the effect of homofermentative and heterofermentative lactic acid bacteria on the chemical and nutritional components of corn silage. The variety of corn used in this study was GWG 4546 at the harvesting age of 110 days. It was ensiled with 10⁵ cfu of LAB for each gram of fresh material. The strains of LAB used to ensile were P. acidilactici (homofermentative LAB), L.plantarum (hetero-homofermentative LAB) and L. fermentum (heterofermentative LAB). The fresh stover was packed in 5L of HDPE plastic jar and kept at room temperature for 28 days. The silages were harvested every week for chemical and proximate analysis. The experimental design was completely randomized design, with 5 treatments x 4 fermentative periods x 3 replicates. From the study, inoculation of homofermentative P. acidilactici produces more lactic acid at an early stage of ensiling, whereas heterofermentative L. plantarum produce more lactic acid at later stages. Furthermore, the crude protein content and metabolizable energy of corn stover silage inoculated with homofermetative LAB were found to be constant throughout the 28 days of fermentation and the values were significantly higher than silages in other treatments. However, there were no significant differences in fibre content, ash content, pH values, dry matter, and fat content among all groups. Therefore, it can be concluded that the addition of homofermentative P. acidilactici resulted in better preservation with improved energy and protein values in 110-days of grain corn stover after 28 days of ensilation.
