Meat Quality Traits

Objective: The QingYu pig is well known for its excellent meat quality attributes in Sichuan province, China. In order to improve its production efficiency, the determination of genetic factors contributing to quantifiable economic traits of livestock is important. Moreover, the cross-breeding of QingYu pigs with western breeds possessing strong growth attributes is an efficient way to improve the performance of this breed.Methods: Here, the genetic parameters of several important reproductive traits of QingYu pigs were estimated, include total number born (TNB), number born alive, litter birth weight, individual birth weight, number of piglets weaned, litter weaning weight, and individual weaning weight. The data was analyzed using the ASReml 3.0 software (NSW Inc., Sydney, Australia). Furthermore, the effects of crossing Berkshire with QingYu (BQ) pigs on carcass and meat quality traits, as well as the effects of slaughter weight on carcass and meat quality of BQ were characterized.Results: QingYu pigs exhibited superior reproductive traits. The TNB available to QingYu pigs was more than 8 per parity. The observed repeatability of the reproductive traits of the QingYu pigs was between 0.10 and 0.23. The significantly correlated genetic and phenotypic of reproduction traits were consistent. Interestingly, the BQ pigs exhibited improved carcass quality, with a significant increase in loin muscle area, lean percentage and reduction in sebum percentage. As a result, BQ had higher L<sub>45min</sub>, lower cooking scores, and lower drip loss. In addition, the loin muscle area, body length, and sebum percentage were significantly higher in 90 and 100 kg animals. Cooking loss showed a significant increase at 80 kg, and marbling increased significantly from 90 kg.Conclusion: The results of this study suggest that QingYu pigs exhibit excellent reproductive properties and heritability of these traits. Crossing with Berkshire is an efficient strategy to improve the carcass and meat quality of QingYu pigs for commercial operations. Furthermore, it appears as though the optimal slaughter weight of BQ pigs is at approximately 90 kg.

With the aim to examine the effect of season and rearing system on major broiler meat quality traits appropriate experimental investigations were conducted. Trial material included a total of 800 one-day-old broilers of the Hybro line hybrid. The experiment was organized in two replications, as trial I (conducted in the spring season) and trial II (conducted in the summer season). Two broiler fattening methods were employed, the intensive and semi-intensive one (using free-range rearing). The experimental chicks were slaughtered after seven weeks of fattening. Following the fattening period, 60 broilers (30 broilers from each experimental group) were chosen at random and slaughtered, with the aim of examining major broiler meat quality traits. At the slaughter line, determination of meat quantitative traits was done accompanied by sampling for chemical analyses. The rearing systems (intensive and semi-intensive system) affected significantly (P &lt; 0.05) the proportion of class I meat in the broilers reared under the semi-intensive system, whereas in the class II and III meat proportions the rearing system did not exert any statistically significant effect (P &gt; 0.05). The broilers reared under the semi-intensive system had a 1.44% higher proportion of muscular tissue on average than the intensively reared ones (P &lt; 0.01). The bone and skin proportion was 0.82 and 0.67% lower in the broilers reared by the semi-intensive method (P &lt; 0.05). The differences between the results of two trials organised at different seasons were not statistically significant (P &gt; 0.05). The broilers reared semi-intensively had a statistically highly significantly higher protein proportion (P &lt; 0.01) in breasts, drumsticks and thighs compared to the intensively reared broilers. The broilers reared in the summer season had higher breast and drumstick proportions (P &lt; 0.01) as well as a higher thigh proportion (P &lt; 0.05). The effect of both the season and the rearing system on the lipid content in the breasts, thighs and drumsticks was statistically highly significant (P &lt; 0.01). The lipid content in the breasts, thighs and drumsticks was higher in the broilers during the summer season as well as in the intensively reared chicken. Finally, having thoroughly examined the research results, or more precisely, considering the established advantages in terms of the meat quality, the use of the free-range broiler rearing system can be deemed scientifically and professionally justifiable. &nbsp;
