Growth and Meat Quality of Prestice Black-Pied and (Landrace × Large White) × Duroc Pigs

Abstract

The objective of the performed experiment was to evaluate growth performance and selected carcass traits and meat quality parameters in pigs of a native Czech breed Prestice Black-Pied pig (PB) and a commercial hybrid (H) used for meat production. The observation included 40 pigs, 20 pigs of the native breed PB and 20 pigs of the hybrid combination. The PB piglets showed higher (P ≤ 0.05) birth weight than the H piglets. The lifetime weight gain was higher (P ≤ 0.01) in the H pigs than in the PB pigs. The results also showed higher (P ≤ 0.01) backfat thickness in the PB breed than in the H pigs. Lean meat content was higher (P ≤ 0.01) in the hybrid pigs than in the PB breed. Higher (P ≤ 0.01) values of intramuscular fat content were found in the PB pigs than in the H pigs. Drip loss value was higher (P ≤ 0.01) in the H pigs by 1.3 % than in the PB pigs. The PB pigs showed more favourable (P ≤ 0.05) values of pH 45,24 in comparison with the hybrid pigs.

Carcass Composition and Physicochemical Characteristics of Meat from Pork Chains Based on Native and Hybrid Pigs

“…The results of the present study are consistent with the results regarding other local breeds reared outdoors and fed either grass, acorn, or chestnut [48], as well as with reports on the fatty acid composition of Prestice Black-Pied breed and Puławska pig breeds raised indoors [1,57]. Furthermore, in their investigation on the differences between the French local Basque breed and the Large White breed reared in conventional and production systems to LW of 145 kg, Lebret et al (2014) [39] found that Basque pigs reared outdoors had increased MUFA and PUFA levels and a decreased SFA share in total fatty acids compared to both Basque animals reared intensively and Large White pigs kept in a conventional production system.…”

“…The obtained IMF values for the meat from the NAT chain were higher than those reported for Krškopolje [55], Celta [56] and Prestice Black-Pied [57] pigs, but they were lower than those for Iberian [58] and Laiwu [59] pigs.…”

Effect of an Outdoor Access System on the Growth Performance, Carcass Characteristics, and Longissimus lumborum Muscle Meat Quality of the Prestice Black-Pied Pig Breed

“…This experiment was performed with the aim of evaluating the effect of providing outdoor access to PBP on their growth, carcass characteristics, and longissimus lumborum muscle meat quality. From the conclusions of previous preliminary studies, where PBPs were compared with a commercial hybrid line in two different production systems, the outdoor rearing system proved to be a more suitable alternative system for this indigenous breed [32].The growth performance and carcass traits evaluated in this study were comparable to those results obtained from the PBP population in previous studies [33,34]. Regardless of the production system used, the results show that PBPs were able to utilize a local protein feed.…”
