Summary: The swine inflammation and necrosis syndrome (SINS) is a visually characterized syndrome that affects specific body parts in pigs, causing inflammation and necrosis of the skin. This syndrome is believed to be influenced by both genetic and environmental factors. Piglets affected by SINS are more susceptible to chewing and biting behaviors from pen mates and may experience reduced welfare throughout the production process. This study investigates the genetic basis of SINS and its relationship with post-weaning skin damage and production traits. The findings suggest that SINS is heritable and selecting against it can improve birth and weaning weights, but it has no significant impact on carcass traits. Selection against SINS is, however, correlated with reduced skin damage after weaning.

Summary: The global production of sheep milk is increasing, with a focus on cheese-making. The heritability estimates for various traits related to cheese-making in Churra sheep ranged from low to moderate, with high genetic correlations observed between certain traits. It is suggested that including the measurement of milk pH as a trait in the Churra dairy breeding program could effectively improve cheese-making ability.

Summary: Carcass value and age at slaughter are important factors in meat sheep enterprises, but their genetic variability is not well understood. This study estimated genetic (co)variances for and among various carcass traits and age at slaughter, as well as their relationship with traits measured earlier in life. The results showed significant exploitable genetic variability in slaughter traits, and the prediction of genetic merit for carcass traits and age at slaughter is possible using live weight measures. The accuracy of selection for slaughter traits increased with the availability of slaughter data on progeny.

Summary: This study reported the genetic heritabilities for growth traits in Lohi sheep and found significant influences of sex, year of birth, and type of birth on these traits. It is recommended to practice selection on the weight at 120 days to improve the growth performance of Lohi sheep.

Summary: The study aimed to determine the genetic parameters of scoured wool colour traits in Corriedale sheep and their correlations with other fleece traits. The heritability of scoured wool yellowness was moderate and should respond to selection, but caution is needed due to its potential negative effects on economically important wool traits. There was also a positive association between mean fibre diameter and scoured wool yellowness. Wool brightness showed low heritability and was only genetically correlated with staple length and wool character.

Summary: The study found that semen quality traits have a certain degree of heritability, and the moderate genetic and phenotypic correlations indicate the predictive value of these traits for service sire NRR. Selection for semen quality traits may be beneficial for improving service sire NRR.

Summary: This study aimed to evaluate the influence of non-genetic factors on growth traits and Kleiber ratios and estimate genetic parameters in Dorper x indigenous crossbred sheep. The study found that genetic improvement might be slow due to the low heritability estimates for birth weight, weaning weight, birth to weaning average daily weight gain, and Kleiber ratio. However, integrating selection with a crossbreeding program could enhance genetic gain.

Summary: The current study estimated genetic parameters (direct and maternal heritability) for pre-weaning body weight traits and Kleiber ratio in Sangsari sheep. The results suggest that genetic improvement of these traits is possible through selection due to low to moderate heritability estimates. Significant genetic correlations were found among early body weights, pre-weaning daily weight gain, and Kleiber ratio in Sangsari sheep.

Summary: This study conducted a meta-analysis to estimate heritability and genetic correlations for 35 traits in sheep, showing that the genetic parameters obtained can be utilized in breeding programs under diverse environmental conditions. The results support the development of sheep breeding programs, particularly in developing and underdeveloped countries where sheep farming plays a significant role in agriculture.

Summary: Performing early selection of breeding goats, considering genetic and environmental factors, can lead to rapid genetic progress and increased profitability in goat breeding. Additionally, accounting for genetic and maternal influences on growth traits is important in identifying individual variations.

Summary: Selecting precocious individuals to shorten the reproductive cycle has minimal effects on gonadal development and productive traits of Crassostrea angulata, except for the egg diameter where it does have a significant effect. This selection method may have a greater impact on females than males.

Summary: This study estimated the genetic parameters of disease phenotypes associated with natural nematode and coccidian infection in Scottish Blackface sheep. The results showed that at 3 months of age, there were strong positive genetic correlations between faecal egg counts of Strongyles and Nematodirus, indicating the feasibility of selecting sheep for resistance to different parasites.

Summary: Genetic selection for production traits in livestock has been successful, but there is a need to improve resilience and efficiency in the face of environmental and disease challenges. This study conducted a meta-analysis to examine the genetic parameters of production, efficiency, and health traits in sheep and goats. The results showed variations in heritability among different traits and species, and evidence of genetic antagonism between production and health in dairy sheep and goats. Simultaneously improving efficiency and health in breeding programs is feasible, but further research is needed to understand the trade-offs between these traits.

Summary: This study reveals possible genetic relationships between sheep breeds in Russia and the Persian Highlands in Iran, based on high-density SNP genotyping. The research shows clear differentiation between Russian sheep breeds of European ancestry and Iranian local breeds, as well as Russian breeds of Asian origin. Admixture analysis also reveals a shared ancestral background in several Iranian and Russian fat-tailed coarse-wool sheep breeds.
