Pigs provided with foraging enrichment during lactation or after weaning tended to have higher serum BDNF concentration than pigs housed in a barren environment, and this effect was significant for pigs enriched during lactation when sampled 5 weeks after weaning.
The possibility of replacing a significant part of pig rations by poultry waste is of great economic importance to mixed farms (pig and poultry).
"It would have to be a major contribution either overall or to specific parts of the brain before I would expect it to have any significant effect on pig behaviour," said Robin Lovell-Badgeneticistticist at the Francis Crick Institute in London.
The results indicated that FEN (in a single therapeutic dose as well as in repeated therapeutic doses) caused significant induction of pig CYP1A, while FLU did not show an inductive effect towards this isoform.
Due to the insufficient sample size, z-test statistics were not significant in the pig data, as the number of observations in each category became small.
An earlier report of a significant association between pig farming and resistant commensal bacteria was published by Aubry-Damon et al. [ 21].
A significant number of pig OR genes (n = 212) showed less than 60% amino acid sequence similarity to known OR genes of other species.
Interestingly, 96% (1411 out the 1464) of the probes identified previously as significant for the pig global immune response were always significant in this analysis even without the PRRS datasets.
Strong associations of multiple SNPs located in intron 9 and 3'UTR with overall leg action and several FL soundness traits suggested that CALCR had significant effects on pig structural soundness and locomotion.
The porcine RYR1 gene (M91451) which had the largest number of LD-specific alternative splicing events has been associated with malignant hyperthermia and has significant effects on pig meat quality and carcass leanness [ 28].
