We identified overlaps of significant CNV segments associated with body weight at days and body weight gain with four previously mapped QTLs for weight traits and residual feed intake (RFI). RFI is de- fined as the difference between actual feed intake and predicted feed intake based on energy requirements for body weight gain and maintenance [46]. associated with performance traits in the TT Reference Population. a BWG: body weight gain from 35 to 41 days.

Relationship between residual feed intake and feed to gain ratio (from Okine et al., 2003).. RFI, by definition, adjusts feed intake for gain and metabolic mid-point weight (Koch et al., 1963). This assertion has been established by studies in Australia (Archer et al., 1998. Jensen et al., 1992). A typical example is the work of Basarab et al. Basarab et al. Archer et al. In addition, Arthur et al.. On the contrary, Arthur et al.. Similarly, a study by Arthur et al.

Intergenic and intronic variants also accounted for a smaller amount of additive genetic vari- ance per DNA variant whereas single regulatory and synonymous variants play a more important role in de- termining variation of the feed efficiency traits. Residual feed intake in beef cattle is controlled by many DNA variants with relatively small effects whereas DMI, ADG, and MWT are influenced by a few DNA variants with large or modest effects plus many DNA variants with small effects.

Effects of alleles in crossbred pigs estimated for genomic prediction depend on their breed-of-origin

Differences between purebred and crossbred, and between breeds-of-origin were evaluated by comparing percentage of variance explained by genomic regions for back fat thickness (BF), average daily gain (ADG), and residual feed intake (RFI). The proportion of genetic variance explained by a genomic region and the estimated effect of a haplotype in such a region were different depending upon the breed-of-origin.

The GADD45 genes are important for intra- cellular communication in the immune system, and were found to be upregulated in the liver of cattle that had higher serum concentrations of cholesterol, or lower residual feed intake, as well as lower levels of cellular growth and proliferation, and lipid metabolism [18, 50].. The p53 signaling pathway and MAPK signaling path- way shared the same significant DEGs (GADD45B and GADD45G) in the present study.

POMC is an important gene in this pathway, which plays an important role in the regulation of feed intake. Furthermore, we found that some path- ways such as adipocytokine signaling pathway, insulin signaling pathway and melanogenesis pathway are involved in the energy homeostasis and regulation of feed intake in chicks, and genes including SOCS1, NFKB1, NFKBIA and PIK3R5 are also related to feed intake regulation..
