Organic acids and their salts have the potential to promote growth in weaner and grower-finisher pigs. The aim of this project was to evaluate the effects of benzoic acid, sodium butyrate and sodium butyrate coated with benzoic acid on the growth per

The body condition score (BCS, on a 0–5 scale) for sheep was developed in the 1960s as a management tool to quickly assess body nutrient reserves. To quantify how live weight, chemical body composition and energy partitioning changes as BCS increas

Embryo transfer of large sheep breed embryos (Suffolk) into small breed ewes (Cheviot) constrains birth size, but the maternal factors influencing fetal growth restriction are unknown. We hypothesized that reciprocal embryo transfer crosses between b

Uterine restriction during gestation can result in the birth of lambs that are smaller than those born from an unrestricted environment. The objective of this study was to examine whether this effect is present during the early embryonic period. Pure

Studies using sheep models indicate that the fetal mammary gland is sensitive to maternal nutrition during gestation; however, results have been inconsistent and do not identify critical feeding periods. This study aimed to clarify previous findings

Pure-bred embryos were transferred within and reciprocally between large (Suffolk) and small (Cheviot) breeds of sheep to establish 4 treatment groups: SinS (Suffolk embryos in Suffolk dams), SinC (Suffolk embryos in Cheviot dams), CinS (Cheviot embr

This study set out to investigate the effects of ewe size and pregnancy nutritional level on the development of singleton-foetuses in late pregnancy and was part of a large study investigating life-time effects of maternal nutrition on the offspring.

This study examined the effects of dam size and plane of nutrition during pregnancy on dam udder size, lamb colostrum intake, and lamb liveweight gain (LWG). The study also attempted to quantify the effects of a number of dam and offspring parameters
