بررسی میزان خوشخوراکی سیلاژ محتویات شکمبه غنی شده با پوست انار و کود مرغی در جیره بره های پرواری

چکیده مقاله

Slaughterhouse waste, particularly ruminant rumen contents, has the potential to serve as an alternative feed source; however, challenges such as unpleasant odors and suboptimal quality must be addressed. This study aimed to evaluate the palatability of rumen content silage enriched with pomegranate peel and processed poultry litter compared to traditional corn silage in the diets of fattening lambs. Rumen contents from cattle, sheep, and goats were collected, filtered, mixed with 20% dried pomegranate peel and 10% processed poultry litter, and ensiled for 45 days. Palatability was assessed using the short-term intake rate (STIR) methodology. The findings indicated that corn silage demonstrated significantly greater palatability than rumen content silages (P < 0.05). Although no statistically significant differences were observed among the various rumen content silages, sheep rumen silage showed a numerically higher intake. The undesirable odor and suboptimal composition of rumen silages were identified as critical factors contributing to reduced animal preference. This study highlights that while rumen contents can be utilized as an alternative feed source, improving their quality and palatability requires enhanced processing techniques and the incorporation of potential flavor additives.
