“…It agrees with the previous studies that have reported on Durox × (Landrace × Large White) and (Pietrain × Large White) × (Landrace × Large White) gilts that surgical castration led to an increase of C16:0 and C18:0 and to a decrease of C18:2n-6 in IMF (Peinado et al, 2011 and2012), although Serrano et al (2008) did not report any significant influence of castration on concentration of these FA profiles in IMF from Duroc × Iberian gilts. This discrepancy could be because of the possible influence of genetic type.…”

“…In the present trial, no influence of immunocastration was observed on colour variables of subcutaneous fat and LT muscle. Several authors (Serrano et al, 2008;Peinado et al, 2011 and2012) neither detected differences between surgically castrated and intact gilts for meat colour. In addition, no significant effect of dietary treatment was observed on colour tissues in line with results reported by Daza et al (2012a and2012b).…”

“…One could have expected an interaction effect of immunocastration and GB diet on IMF, but this was not achieved in the present study. Some studies reported that female castration led to a slight, although not significant, increase in IMF percentage (2.4 v. 2.0; Peinado et al, 2011 and2012). Previously, Daza et al (2010 and2012b) observed that the use of a diet based on GB led to an increase in IMF content.…”

“…In a recent study, Gómez-Fernández et al (2013) observed that Duroc × Iberian IG had higher ADG, ADFI and FCR than EG. On the other hand, Peinado et al (2012) reported in (Pietrain × Large White) × (Landrace × Large White) gilts, Standard error of the mean, calculated using n = 24 pigs as experimental units per main effect of sex or diet. b ns = not significant (P >0.10); + P < 0.10; *P < 0.05; **P < 0.01.…”

“…According to Peinado et al (2011 and2012), the surgical castration might be a strategy, but it also carries out negative consequences on animal welfare. For that, currently, the immunocastration against GnRH appears as an interesting chance.…”

A total of 48 Duroc × (Landrace × Large White) gilts of 33.2 kg BW were used to investigate the influence of immunocastration and diet on growth performance and carcass, meat and fat quality. Four treatments were arranged factorially (2 × 2) with two sexes (immunocastrated gilts: IG v. entire gilts: EG) and two dietary treatments (a commercial feedstuff as control v. granulated barley as a single major ingredient) provided during the finishing period (from 103 to 126 kg BW). There were four replicates of three pigs per treatment. At the end of the trial, the IGs grew faster ( P < 0.05) and ate more feed ( P < 0.05) than the EGs. Carcasses from the IGs had thicker backfat depth than those from the EGs ( P < 0.01) and carried out a lower percentage of rejected carcasses ( P < 0.05) at slaughterhouse owing to lack of fat. Meat from the IGs tended to have higher intramuscular fat (IMF) content in the Longissimus thoracis (LT) muscle than that from the EGs ( P = 0.09). In addition, immunocastration increased the total saturated fatty-acid proportion in subcutaneous fat and IMF ( P < 0.001) and decreased the total monounsaturated fatty acid (MUFA) and total polyunsaturated fatty acid (PUFA) percentages in subcutaneous backfat ( P < 0.05 and P < 0.001, respectively) and in IMF ( P < 0.01 and P = 0.06, respectively). The use of a diet based on granulated barley during the finishing period had no effect on growth performance but tended to increase IMF content in the LT muscle ( P < 0.06), and increased MUFA ( P < 0.05) and decreased PUFA ( P < 0.01) proportions in omental fat. It is concluded that immunocastration of gilts intended for dry-cured ham industry improved some aspects of growth performance and carcass and meat quality, whereas granulated barley had scarce effect on productive traits and fatty-acid profile but tended to improve IMF content.

The effects on finishing pigs (80–100 kg BW) fed diets supplemented with oil sources containing different ratios of unsaturated to saturated fatty acids (UFA:SFA ratio) were evaluated in 15 barrows and 15 gilts (Duroc × Large White × Landrace). Three experimental diets were evaluated using a randomized complete block design, with broken rice, soybean meal and rice bran as the main feedstuffs in the control diet. Diets 2 and 3 consisted of the control diet supplemented with 3% oil, with UFA:SFA ratios of 2.5:1 and 5:1, respectively. Overall, there was no significant difference (P > 0.05) found in the average daily gain (ADG) of the pigs fed the treatment diets; however, the pigs fed the control diet and diet 3 had better (P < 0.05) feed conversion ratios (FCR) than the pigs fed diet 2. The pigs fed diets 2 and 3, which were supplemented with oil at UFA:SFA ratios of 2.5:1 and 5:1, had greater (P < 0.05) average daily feed intakes (ADFI) than the pigs in the control group. Additionally, it was found that the gender of the pigs had an effect (P < 0.05) on the FCR. Interaction effects between the experimental diets and the gender of the pigs (P < 0.05) were found in the ADFI and FCR. There were no significance differences (P > 0.05) among the treatment groups with regard to the carcass quality of the pigs; however, it was found that the gilts had greater (P < 0.01) loin eye areas than the barrows fed diets 2 and 3 and the loin eye area of pig fed diet 2 was the largest (P < 0.05). In the case of the meat quality parameters, it was clearly found that the pigs fed the control diet had a greater (P < 0.05) lightness (L∗) in the meat colour, and the lowest cooking loss was found in the pigs fed the diet supplemented with fat containing the UFA:SFA ratio of 5:1. Overall, the dietary treatment did not significantly affect the drip loss, thawing loss and shear force of the pork. In conclusion, the supplementation of oil with UFA:SFA ratios of 2.5:1 and 5:1 has the potential to improve pork quality.
