The role of L-carnitine in the control of oxidative stress and lipid β-oxidation during follicle growth, oocyte maturation, embryonic development and cryopreservation: a review.

L-carnitine has an important role in the control of oxidative stress and lipid β-oxidation during culture and cryopreservation of ovarian follicles, oocytes and embryos. This substance balances the acetyl-CoA/CoA ratio, maintains glucose metabolism and increases energy production in mitochondria. It also plays a key role in reducing endoplasmic reticulum stress, by transferring palmitate to mitochondria or eliminating it to avoid toxicity.

Thermoregulatory, behavioral and productive responses of laying hens supplemented with different types and dosages of phytases raised in a hot environment: An integrative approach.

This study had the following objectives: (i) to evaluate the thermoregulatory and behavioral responses of light laying hens supplemented with different types and dosages of phytases in the two day shifts; and (ii) to integrate the thermoregulatory and behavioral responses with performance of these birds raised in a hot environment. 270 light laying hens of the Hy-Line White lineage, with a body weight of 1.60 ± 0.

Thermoregulatory capacity of hair ewes of different genotypes associated with coat colors raised in a hot environment.

The relationship between hair color characteristics and thermoregulatory responses in ewes raised in hot environment were evaluated. 15 hair ewes of different genotypes associated with coat colors (light brown, dark brown and black) with body weight of 41.2 ± 8.
