Embryo yield and quality following dietary supplementation of beef heifers with n-3 polyunsaturated fatty acids (PUFA)

The objective of this study was to examine the effects of dietary n-3 polyunsaturated fatty acid ( n-3 PUFA) supplementation on embryo yield and quality in heifers. Animals were individually offered barley straw and concentrate diets supplemented with either palmitic acid (C16:0; CON) or a partially...
