“…Our results align with those of Van Ba et al (2019) and Lee et al (2019) , who reported similar trends for the fat content in pork and beef LD muscles from different QG groups. Compared with our data, those of Lowell et al (2019) and Soladoye et al (2017) found higher fat content (33%–46%) and lower moisture (41%–49%) in belly cut of Duroc and Peitrain breeds finished at heavier weight (130–135 kg). These contrasting results are probably due to the differences in the sampling position, slaughter weight and breed used between the studies.…”

“…Overall, loins from Duroc-sired pigs had greater levels of loin pass rate (defined as Japanese color score ≥ 3.0 and marbling ≥ 2.0) compared with Duroc–Pietrain-sired pigs, loins from barrows had greater levels of loin pass rate compared with gilts, and Improvest-treated gilts had greater levels of loin pass rate compared with untreated gilts. Similar findings have been reported by previous researchers; for instance, both Lowell et al. (2019) and Redifer et al.…”

The objective was to evaluate the effects of Improvest® on performance and carcass characteristics of gilts from two different genetic sire lines and the performance of Improvest gilts with castrated male pigs. It was hypothesized that performance parameters observed for Improvest gilts would be similar to barrows, thus narrowing the performance gaps between traditionally-managed gilts and barrows. Pigs were from Large White/Landrace dams and either Duroc-Pietrain (DP) or Duroc (D) sires. Females within each genetic sire line were randomized by weight to receive the first dose of Improvest (IMP) on day 25 of the study or to serve as a non-treated control (DP IMP gilt (n = 6 pens; 19 pigs/pen), D IMP gilt (n = 6 pens; 19 pigs/pen), DP CON gilt (n = 6 pens; 19 pigs/pen), D CON gilt (n = 6 pens; 19 pigs/pen). The second dose of Improvest was administered 6 weeks later (i.e., day 67). Barrows did not receive Improvest (DP barrow (n = 10 pens; 19 to 20 pigs/pen), D barrow (n = 10 pens; 19 to 20 pigs/pen)). Average daily gain (ADG), average daily feed intake (ADFI), and gain to feed ratio (G:F) were measured at 21 d intervals throughout the duration of the study. The targeted weight for pigs to be marketed was 133 ± 2.5 kg. Carcass characteristics and loin quality parameters were evaluated on a subset of pigs (n = 283). Improvest treated gilts of both genetic lines had increased (P ≤ 0.05) ADG and ADFI compared to untreated gilts during the post-second dose intervals with values exceeding that of barrows from day 84 to marketing. Overall, DP IMP gilts had increased (P ≤ 0.05) G:F post second dose compared to DP CON gilts and DP barrows, yet all other treatments were similar. As pigs were marketed at a similar weight, there was no difference in final weight, however, DP IMP gilts and DP barrows reached market weight sooner (P ≤ 0.05) than DP CON gilts (109.9 and 111.8 vs. 114.3 ± 0.8 days). Backfat and loin weight were greater (P < 0.01) in IMP gilts vs CON gilts, while IMP gilts and barrows had similar values within each respective genetic sire line. There were no differences between treatments (P ≥ 0.08) for pH and instrumental color of the loins. When pass rate of loins (Japanese color score ≥ 3.0 and marbling ≥ 2.0) were evaluated, IMP gilts were at intermediate values between CON gilts and barrows for each respective genetic sire line. Overall, Improvest within a genetic line improved gilt carcass measurements so that they were more similar to barrows.

“…Production efficiency of fattening pigs in terms of average daily gain, feed efficiency and carcass composition is a heritable trait complex (Aymerich et al, 2019;Cámara et al, 2016;Latorre et al, 2003;Serrano et al, 2008), for which considerable heterosis effects are harnessed in crossbreeding schemes (García-Casco et al, 2012;Katoele et al, 2002;Luo et al, 2018). In commercial pig production, the dam line is usually fixed, and as a consequence of artificial insemination (AI) sire line selection is flexible.…”

Abstract. A variety of available terminal sire lines makes the choice of terminal sire line complex for the pig producer. Higher birth weights are important for subsequent growth performance and selection for this trait is also necessary in sire lines. The aim was to investigate the effect of sire line, birth weight and gender on growth performance, carcass traits and meat quality. In total 3844 crossbred pigs from Camborough Pig Improvement Company (PIC) dams matched with either a Synthetic (A) or Piétrain (B) sire line were used. Pigs from line A grew faster (p<0.01), showed higher feed intake (p<0.01) and reached a higher final body weight (p≤0.01), but they had a similar efficiency (p=0.179). Leaner carcasses and heavier primal cuts (p<0.001) were observed in pigs from line B. Carcasses from pigs sired by line A had higher meat quality (p<0.001). Males had a higher growth rate (p≤0.05) but had a poorer feed efficiency (p<0.01). Heavier birth weight pigs and females had leaner, higher value carcasses with heavier primal cuts (p<0.001) compared to middle and low birth weight females or males. Sire line by sex interactions was significant for growth (p≤0.05) and carcass traits (p<0.001). Interaction between sire line and birth weight classes were only detected for loin depth (p<0.01). Line A is preferable if the numbers of fatting pigs per fattening place and year should be improved, and line B is an option to increase leanness and carcass primal cuts.
