Genetic Parameter Estimation for Plasma Biomarkers Associated With Energy Reserves During Critical Physiological Stages in Sheep

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT The ability of ruminants to mobilise and restore body reserves (BR) over time, referred to as BR dynamics, is currently considered an interesting biological component to be included in breeding programs targeting enhanced BR resilience. However, genetic studies of proxies for BR levels and BRD remain scarce, particularly in small ruminants ...

Impact of bioactive substances on the gastrointestinal tract and performance of weaned piglets: a review [PDF]

open access: yes, 2009
The EU ban on in-feed antibiotics has stimulated research on weaning diets as a way of reducing post-weaning gut disorders and growth check in pigs. Many bioactive components have been investigated but only few have shown to be effective.

Scientific Opinion on the efficacy of Suilectin TM (Phaseolus vulgaris lectins) as a zootechnical additive for suckling piglets (performance enhancer) [PDF]

open access: yesEFSA Journal, 2015
Abstract SuilectinTM is a preparation of Phaseolus vulgaris (kidney bean) lectins which contains a mixture of five phytohaemagglutinin (PHA) isoforms: PHA‐E4, PHA‐E3L, PHA‐E2L2, PHA‐EL3 and PHA‐L4. The Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) issued an opinion on the safety and efficacy of SuilectinTM as a zootechnical

Impact of Model Parameterisation and Variance Component Estimates on Genomic Predictions of Carcass Traits in Montana Composite Cattle

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT This study evaluated the influence of variance component (VC) estimates, obtained from different models and two relationship matrices, pedigree‐based (BLUP) and genomic information‐based (ssGBLUP), on genomic predictions of carcass traits in Montana composite cattle.
