“…A sex-related effect on the FA profile has been reported in many studies (Segura et al 2015a;Daza et al 2016;Egea et al 2016). Differences between males and females were similar in SCF, IMF and the PL fraction of the liver.…”

This study aimed to determine the effects of piglet birthweight (BIW) and sex, and within-litter BIW variation, on postnatal growth traits and meat quality in fatty breeds of pig. In total, 406 crossbred piglets (half male, half female) born to Iberian sows were studied during their postnatal development until slaughter. After birth, piglets were classified into four BIW categories: very low, low, medium and high. There was a negative effect of low BIW on growth patterns and fatty acid (FA) composition, but effects of litter size and within-litter BIW variation were not found. The very low BIW piglets underwent a period of significant catch-up growth (P < 0.005) relative to high BIW piglets during the early postnatal phase, but also showed a higher feed conversion rate and lower average daily weight gain (P < 0.05 for both measures) throughout the study period. BIW affected development during the entire productive life, and the sex effect increased with age. As a result, the period to reach market weight was longer in very low BIW piglets, by 43 days for females and 15 days for males, compared with their high BIW counterparts. BIW and sex also influenced amount of intramuscular fat, n-3 FA content and monounsaturated FA composition. The study indicates that BIW, modulated by sex, is a critical point for productive traits in fatty pigs. These results provide a basis for future strategies to enhance productive efficiency and meat quality of traditional swine breeds.

“…These authors suggested that the increase in voluntary ADFI observed in the IMC might have resulted in an increase in gut content and consequently, in lower carcass yield. Backfat depth was lower for boars than for gilts and IMC, in agreement with data of Morales et al (2010) and of Daza et al (2016) comparing CM, IMC, IF, and immunocastrated females.…”

“…Gispert et al (2010), however, reported that carcass yield was higher for gilts than for boars and higher for both than for IMC. In contrast, Daza et al (2016) reported no differences in carcass yield among IF and IMC. The reasons for the discrepancies in respect to carcass yield of boars and IMC between experiments are unknown but may be due to differences in ADFI and final BW of the pigs.…”

“…For the entire experimental period, IMC had higher ADFI and ADG than gilts and boars, in agreement with data of Fàbrega et al (2010) in pigs slaughtered at 120 kg BW. However, Daza et al (2016) Morales et al (2010). Gispert et al (2010), however, reported that carcass yield was higher for gilts than for boars and higher for both than for IMC.…”
