The transition period of dairy cattle is characterized by a number of metabolic, endocrine,
physiologic, and immune adaptations, including the occurrence of negative energy balance …

Mammals can synthesize all of the fatty acids (FA) necessary for proper health and
functioning with the exception of FA in the n-3 (omega-3) and n-6 (omega-6) families of …

Mammalian oocytes and early cleavage-stage embryos are critically dependent on their~
100,000 mitochondria to develop from ovulation to compacted morula stage. They rely …

The positive effects of fat and energy supplementation on improvements in reproduction are
well documented. However, the specific effects of omega-3 polyunsaturated fatty acids (n-3) …

Abstract Linoleic acid (LA; 18: 2 n-6) is the most abundant fatty acid in bovine follicular fluid,
and it was previously reported that LA concentration significantly decreases when follicle …

The evidence that omega-3 (n-3) and-6 (n-6) polyunsaturated fatty acids (PUFAs) have
differential effects on ovarian function, oocytes and embryo quality is inconsistent. We report …

Reduced oocyte and embryo quality are recognised as major factors in the problem of
disappointing fertility in high producing dairy cows. This review aims to shed more light on …

Contents In many countries, fat supplementation in the diet has become common in the dairy
industry. There are several ideas as to how dietary fat could influence reproductive …

Abstract Hypoxia-inducible factor 1 (HIF1) is a heterodimeric transcription factor, consisting
of a constitutively expressed β-subunit (HIF1B) and a regulated α-subunit (HIF1A). In the …

The objectives of this study were to determine the differential incorporation of various omega-
3 (n-3) fatty acids (FAs) supplemented to dairy cows into ovarian compartments and assess …
