Ear tags may result in an inflammatory response due to the wound created when they are inserted into the ear. The aim of this study was to determine the effect of ear tags on the likelihood of infection using infrared thermography and to evaluate the effect on the welfare of the lambs. Infrared thermography can be recommended as a tool to determine this type of stress and consequently allow a better evaluation of animal welfare.

Short summary
Ewes' reproductive performance could be predicted using the data available early in their life. Ewe birth rank, dam birth rank, first litter size, and first lambing interval are significantly associated with ewe reproductive performance up to the fourth year of life. Precise prediction of ewe reproductive performance using the early predictors is impossible due to the low R2 predicted. The value of the lower threshold of the 95 % prediction interval might be useful in making selection decisions.

Genes enriched in sensory perception were positively selected via selection signature analysis between wild Asiatic mouflon and domesticated Hu sheep. Among them, RDH5 is one of the key enzymes in the synthesis of retinoic acid (RA), which is related to human retinopathy. The c.722T>C/p.M241T mutation of RDH5 affects retinol dehydrogenase activity in the domestication process of sheep.

This study aimed to understand the effects of adding low-dose oxytocin hormone into ram semen on the pregnancy rate and reproductive efficiency of sheep. A total of 53 out of 122 Chios ewes were inseminated with oxytocin hormone content, and successful pregnancy was achieved 90.56 % of them. In examination of the pregnancy rate, one of the indicators of reproductive performance, the difference between the groups is statistically significant (p = 0.046; p ≤ 0.05).

Three-way crossbreeding was performed with Australian White, Dorper, and Charollais as terminal male parents and elite F1 hybrids of Australian × Han, Dorper × Han, and Charollais × Han as female parents. Based on the growth of three-way crossbred and Small-tailed Han lambs as well as the effects of CLPG, the offspring of male Australian White and female Charollais × Han showed apparent heterosis, and the individuals with the T allele had improved body weight and body size.

Factors such as genotype, sex, type of birth, maternal age, weaning age and birth weight must be considered in evaluation of pre- and post-weaning growth traits. Myostatin mutation was introduced to native Turkish breed Ramlıç by marker-assisted introgression (MAI). The mutation has a positive effect on ultrasonographic carcass traits in crosses. Lambs with myostatin tended to have deeper longissimus muscle and good carcass characteristics, and they may be recommendable for Turkish farmers.

We studied the impact of the COVID-19 restrictive measures on the extensive farming system of small ruminants. We found that the breeders’ daily work routine was negatively affected in holdings with a high number of sheep. The majority of breeders did not change the movements of the animals in pastures, the amount of the given feedstuffs, the hygienic conditions on the farms, or the employed workers. A decrease in demand for animal products and a decrease in their prices were observed.

Here we clarify the specific expression and mechanism of the EPH receptor and Ephrin during the development of hair follicles, as well as their upstream and downstream signaling pathways and activation pathways. This study verified the effect of EPHA4 and Ephrin A3 genes on fine-hair follicles through RT-qPCR and immunohistochemistry testing. It is of great significance as it could speed up the promotion of breeding sheep for wool.

This research aimed to determine the effects of body weight, the body condition score (BCS), body measurements, birth type, birth weight and sex on the gestational length in sheep. The lowest and highest gestational lengths were found to be 148.90 and 151.41 d respectively. It is thought that the use of the BCS, which is easily applied by the breeder, will have a positive effect on determining the bodily reserves of sheep and the reproductive efficiency as well as on obtaining healthy lambs.

Fatty acid composition in the intramuscular fat of the musculus longissimus dorsi of Ile de France purebred lambs in two production systems (lambs and ewes were assigned to pasture and fed without concentrates vs. lambs and ewes were assigned to a stable and fed with hay/silage and concentrates) was evaluated using gas chromatography. An analysis of variance was used for comparison. No such comparison had previously been carried out in Slovakia. Meat from lambs assigned to pasture was better.

In sheep production, the body condition scores and parities are important environmental factors affecting lamb yield. Extreme body condition scores (fattening state) lead to negative effects on lamb yield. In the present study, it was revealed that ewes with medium and fat body condition scores (BCS: 2.5–4.0) were profitable. It was shown that the body condition score had minimal effects on the birth weights of lambs, and the incidence of dystocia was increased in thin and very fat ewes.

The aim of this study was to perform a multivariate analysis of lambs' birth weight, survivability traits, growth performance traits, and other defined factors. The study focused on one flock of Suffolk sheep kept under permanent pasture management. Overall 1012 lambs were investigated over 3 years. The results of the study detected lambs' optimal birth weight for this management system. This study also suggested practical implications of important factors when improving flock profitability.

We aimed to evaluate the effects of premating ewe weight and age on ewe reproductive performance and lamb growth and survival in Central Anatolian Merino sheep. Multiple birth rate, birth weight, and growth performance of the lambs increased proportionally with the increase in live weight of the ewes prior to mating. Therefore, it is important to increase the live weight of lambs at puberty and to select ewes that attain a higher premating weight for breeding.
