Effect of premix ingredients and its inoculation with lactic acid-producing bacteria on ensiling of poultry droppings with conventional feeds
1992
Kamra, D.N. | Srivastava, S.K.
A premix of poultry droppings (25 parts) and wheat straw (65 parts) was inoculated with a mixed culture of Lactobacillus plantarum and Streptococcus faecalis in the presence or absence of sugarcane molasses. The inclusion of lactic acid-producing bacteria and molasses in the premix resulted in reduced pH, ammonia nitrogen and total volatile fatty acids and increased production of lactic acid during a fermentation time of 20 d at 32-35 degrees C. The sugarcane molasses and part of the wheat straw can be replaced with green maize fodder in the vegetative stage without any adverse effect on the silage characteristics. With an increasing level of green maize in the premix, there was a decrease in pH, dry matter of premix and wastelage and a significant increase in soluble sugars of premix and titrable acidity and lactic acid content of wastelage. A good wastelage can be produced when the premix consists of poultry droppings, wheat straw and green maize in the ratio of 25:15:60, respectively, and it is inoculated with lactic acid-producing bacteria.
