“…A three-generation design was performed by inter-crossing two experimental meat-type chicken lines that were divergently selected on abdominal fatness and named [17] the fat (FL) and lean (LL) lines. In the F 0 generation, 9 FL males were mated to 12 unrelated LL females to generate the F 1 generation.…”

-Quantitative trait loci (QTL) for abdominal fatness and breast muscle weight were investigated in a three-generation design performed by inter-crossing two experimental meattype chicken lines that were divergently selected on abdominal fatness. A total of 585 F 2 male offspring from 5 F 1 sires and 38 F 1 dams were recorded at 8 weeks of age for live body, abdominal fat and breast muscle weights. One hundred-twenty nine microsatellite markers, evenly located throughout the genome and heterozygous for most of the F 1 sires, were used for genotyping the F 2 birds. In each sire family, those offspring exhibiting the most extreme values for each trait were genotyped. Multipoint QTL analyses using maximum likelihood methods were performed for abdominal fat and breast muscle weights, which were corrected for the effects of 8-week body weight, dam and hatching group. Isolated markers were assessed by analyses of variance. Two significant QTL were identified on chromosomes 1 and 5 with effects of about one within-family residual standard deviation. One breast muscle QTL was identified on GGA1 with an effect of 2.0 within-family residual standard deviation.

“…Total RNA was purified from the liver of 15-day-old chickens from a line selected for high abdominal fat pad [38]. Animals were deprived of food for 48 h and then re-fed a high-carbohydrate diet for 36 h in order to stimulate lipogenesis [5,39,40].…”

Acetyl-CoA carboxylase is a rate-limiting enzyme in the biogenesis of long-chain fatty acids. In the present study, the 5h end and flanking region of the acetyl-CoA carboxylase (ACC) gene was analysed in the chicken. A genomic clone was isolated containing the first three exons, the third one containing the ATG codon. Using nuclease-mapping experiments and primerextension analyses, the transcription-initiation site was located 153 nucleotides upstream of the ATG codon. In contrast with rat ACC gene expression, reverse transcriptase PCR analysis performed on chicken liver mRNA did not reveal alternative splicing in the 5h-untranslated region of these messengers.

“…Therefore, many experimental direct or indirect selection programmes against carcass fatness were undertaken. Direct selection against abdominal fat (AF) using sib-test procedures was undertaken in France by Leclercq et al (1980), Israë l by Cahaner and Nitsan (1985) and the Netherlands by Leenstra and Pit (1987). One study using hand palpation of AF pad thickness was conducted on mature females by Lilburn et al (1982).…”

Divergent selection of chickens for low or high abdominal fat (AF) but similar BW at 63 days of age was undertaken in 1977. The selection programme was conducted over seven successive generations. The difference between lines was then maintained constant at about twice the AF in the fat line as in the lean line. The aims of the first studies on these divergent chicken lines were to describe the growth, body composition and reproductive performance in young and adult birds. The lines were then used to improve the understanding of the relationship between fatness and energy and protein metabolism in the liver, muscle and adipose tissues, as well as the regulation of such metabolism at hormonal, gene and hypothalamic levels. The effects on muscle energy metabolism in relation to meat quality parameters were also described. This paper reviews the main results obtained with these lines.
