Abstract
A wastelage of swine faeces, wheat bhoosa, chaffed oat forage ( Avena sativa) and molasses in the ratio of 3:3:3:1 on a fresh weight basis was prepared on a laboratory scale by ensiling in polythene bags and on a large scale in a stainless steel cylindrical tower silo. The process of ensiling resulted in improvement of flavour and a significant decrease in the number of pathogenic micro-organisms. There was a marked increase in the number of lactic acid-producing bacteria and acidity of the wastelage (the fermented product) and a decline in the total number of bacteria, and in fungi, clostridia, salmonellae and coliforms. The pH of the wastelage was in the range 4·1 to 4·3 at various depths of the stainless steel silo. The nutritional evaluation of wastelage showed that the dry matter intake was 2·07 and 2·33 kg per 100 kg body weight in sheep and buffalo, respectively. The digestible crude protein (DCP) and total digestible nutrient (TDN) contents in wastelage dry matter were 3·23 and 47·05 for sheep and 3·30 and 50·30 for buffalo, respectively. The animals maintained their body weights during the course of an experiment on ad libitum feeding of wastelage.
