Genetic Architecture of Feeding Behavior and Feed Efficiency in a Duroc Pig Population [PDF]
Frontiers in Genetics, 2018 Increasing feed efficiency is a major goal of breeders as it can reduce production cost and energy consumption. However, the genetic architecture of feeding behavior and feed efficiency traits remains elusive. To investigate the genetic architecture of feed efficiency in pigs, three feeding behavior traits (daily feed intake, number of daily visits to ...

Joint contributions of the gut microbiota and host genetics to feed efficiency in chickens
Microbiome, 2021 Background Feed contributes most to livestock production costs. Improving feed efficiency is crucial to increase profitability and sustainability for animal production. Host genetics and the gut microbiota can both influence the host phenotype.

Assessing the relationship between the rumen microbiota and feed efficiency in Nellore steers
Journal of Animal Science and Biotechnology, 2021 Ruminants rely upon a complex community of microbes in their rumen to convert host-indigestible feed into nutrients. However, little is known about the association between the rumen microbiota and feed efficiency traits in Nellore (Bos indicus) cattle, a
