During the peripartum period (3 weeks before through 3 weeks after calving, a.k.a. “transition”), high producing dairy cows experience, among others, , oxidative stress and immune suppression that compromise performance and increased incidence of diseases.Among trace minerals, supplementation of Selenium (Se) can help to improve the transition by enhancing glutathione...
Nutrigenomics is a branch of nutrition that seeks to elucidate the relationship between dietary components and expression of genes. Certain bioactive compounds present in the diet have the potential to modulate transcription of genes through their interactions with ligand-dependent nuclear receptors, a series of transcriptional regulators capable of sensing intracellular...
Oxidative dysfunction can affect dairy animals during periods of heightened stress, particularly during the transition from pregnancy to lactation and during diseases, such as intramammary infection (IMI), and can contribute to increased inflammation, immune dysfunction, and cell death. As such, methods for ameliorating oxidative stress and restoring redox regulation may...
As the world population continues to grow we must look for smarter and more sustainable ways to feed everyone. Milk is the first food humans consume and is a good source of protein, fat, and carbohydrates. The following studies sought to determine the effect of feeding blackberry pomace as a...
Grasslands in the Pacific Northwest are characterized by seasonally wet, acidic soils that mainly support cool season grasses and a limited number of legume species. A major limitation to efficient animal production in grass-dominant pastures is the decline in the herbage growth rate and nutritional quality of forage from late...
To evaluate the immunologic and metabolic effects of OmniGen-AF® (Phibro Animal Health corporation, Quincy, IL; OG) supplementation in growing beef cattle, we designed three studies using replacement beef heifers (8.5 and 10.5 months of age) and steers supplemented across backgrounding, transition, and finishing periods. In Study 1, the effect of...
Mycotoxins are food-borne toxins produced by molds which are commonly found on animal feeds of economic significance. Toxic doses of these compounds vary widely across livestock species, and even within a species when considered across all stages of development and production. This variation is due to the wide range of...
Systems biology is a powerful approach which considers and sheds light on all of the puzzle pieces which make up complex biological processes, and is an effective alternative to unraveling these processes using traditional molecular approaches alone. It is a natural companion approach for computational biology, which leverages the power...
Sheep are seasonally polyestrus, which means they do exhibit estrus and ovulation during the short daylight (breeding season) and do not during the long daylight (nonbreeding season). To stimulate the ewes to ovulate during the nonbreeding season, various hormonal treatments have been used. PG-600 contains both equine chorionic gonadotropin and...
