“…The higher dressing percentage of female lambs in our study could explain why higher daily gains of male lambs did not cause a difference in hot carcass weights between males and females. In agreement with Facciolongo et al (2018), the meat of male lambs in our study was significantly lighter than the meat of female lambs, while redness of meat was not affected by sex. In our research, no difference in the yellowness of meat was observed, while the study of Facciolongo et al (2018) showed that male lambs' meat had significantly higher values of yellowness than female lambs.…”

“…Male lambs had significantly higher hot carcass weight than female lambs, while there was no significant difference in dressing percentage between sexes. In the present study, contrary to the results of Perez et al (2007), female lambs had significantly higher dressing percentage than male lambs, probably due to significantly higher subcutaneous and internal carcass fatness, as concluded by Facciolongo et al (2018). The latter study found similar results with female lambs having significantly higher dressing percentages compared to male lambs.…”

Background: In ruminants, due to the hydrogenation of the rumen, muscles contain a large amount of saturated fatty acids (SFA), which have a negative effect on meat quality. Linseed as a common oil crop which is rich in polyunsaturated fatty acid (PUFA), it affected the deposition of PUFA. Unfortunately, PUFA can exert a negative influence on the oxidative stability of meat. Fortunately, linseed is not only rich in PUFA, but also rich in phenols, which are a good source of antioxidants. Therefore, linseed may be can serve as an effective feed additive to improve meat quality of sheep. The aim of this investigation was to establish the effects of dietary linseed supplementation on carcass traits, meat quality, muscle fiber characteristics and antioxidative capacity of sheep. Results: Results of this study indicated that linseed supplementation significantly increased the loin-eye area, crude protein and ash. Reduced pH24h, L* and shear force. Moreover, linseed supplementation affected the relative content and enriched the kinds of volatile flavor substances. Increased mRNA expression of MyHC I and MyHC IIx, and a decrease in cross-sectional area (CSA) and muscle fiber diameter was also observed. Additional changes included enhanced activity of succinic dehydrogenase (SDH), decreased activity of lactate dehydrogenase (LDH), increased total antioxidative capacity (T-AOC) activity. The mRNA expression of glutathione peroxidase (GSH-PX) and catalase (CAT) were increased while malondialdehyde (MDA) decreased. Conclusions: The results suggest that linseed is an effective feed additive in improving meat quality. The underlying mechanism(s) for its effectiveness may be partly due to a change in muscle fiber characteristics and antioxidative capacity.

“…Genotype did not show any influence on the dissection data of the loin and leg (Table 4). In small ruminants, tissue composition of meat cuts is influenced by nutrition, gender, litter size and body weight [3,6,12]. Moreover, fat depots may develop in a different way in relation to the animal genotype and age; goat carcasses have usually more than 60% dissectible lean and about 5-14% fat [3].…”

Sustainable Rearing for Kid Meat Production in Southern Italy Marginal Areas: A Comparison among Three Genotypes

et al. 2020

Sustainable goat breeding plays an important role in the economy of marginal areas. The present study aimed to compare performances and meat quality traits in kids of a native Apulian genotype (Garganica) in comparison with two Mediterranean breeds (Maltese and Derivata di Siria). Kids suckled dam milk until they were 21 (±2) days old, hence three groups of 12 male kids per each genotype were made. The kids received a pelleted feed ad libitum in addition to dam milk and were slaughtered at 60 days of age. The Maltese kids showed the lowest net cold-dressing percentage, with statistical differences compared to Garganica and Derivata di Siria. Meat obtained from Garganica kids showed a rosy color due to a significantly lower a* index and were also more tender since a lower WBS was recorded in comparison with the other two genotypes. As for the nutritional value of meat, the best n-6/n-3 ratio was found for the Derivata di Siria breed. In conclusion, Garganica kid meat showed the lowest content of SFA and atherogenic index, with potential beneficial effects for human health.
