The volatile organic compounds and palatability of mixed ensilage of marigold (Tagetes erecta L.) crop residues

With increasing acreage of cash crops, the use of their by-products as supplements for livestock feed becomes an important factor. Marigold ( Tagetes erecta L.) account for more than half of the world’s loose flower production. However, there is no precedent for the abundantly available marigold cro...

Description
Summary:With increasing acreage of cash crops, the use of their by-products as supplements for livestock feed becomes an important factor. Marigold ( Tagetes erecta L.) account for more than half of the world’s loose flower production. However, there is no precedent for the abundantly available marigold crop residue (MCR) being used as feed in agricultural production, probably because of its strong pungent taste. This study aimed to evaluate the biotransformation of the volatile organic compounds (VOCs) of MCR by mixed ensilage and assess its palatability by cattle. Caryophyllene, the most prevalent VOC in MCR, decreased by 29.11% ( P
