The g.405442728A>G locus of HRG exhibited moderate polymorphism (0.25<PIC<0.5) in these breeds, indicating this locus has great selection potential. It is accurate to say HRG can be used as a molecular marker to increase litter size in Small-tailed Han sheep (STH). The g.405442728A>G locus of HRG and the g.421655951C>T locus of FETUB had a significant effect on litter size in STH (P<0.05). We can use HRG and FETUB as candidate genes for the selection of litter size in sheep breeding.

Finding polymorphisms of genes can provide potential molecular genetic markers for sheep reproduction. This study investigated the polymorphisms of three major reproductive genes (BMPR1B, BMP15 and GDF9) in Chinese sheep and found that BMPR1B and GDF9 might be the major genes influencing the reproductive performance of Chinese sheep breeds. This result might contribute to improving the prolificacy traits of native Chinese sheep in the future.

In this study, GLUD1 single nucleotide polymorphisms (SNPs) were analyzed in early-puberty goats and delayed-puberty goat breeds by sequencing and restriction fragment length polymorphism (RFLP). The present study aimed to find genetic markers related to sexual precocity and high fertility in goats and to provide a scientific basis for marker-assisted early selection of reproductive performance.

Our results suggest that estrous cycles may be associated with clock gene expression in the Small-tailed Han sheep (STH sheep). This is the first study to systematically analyze the expression patterns of clock genes of different estrous cycles in ewes, which could form a basis for further studies to develop the relationship between clock genes and the estrous cycle.

The expression and polymorphism of the BMPR1B gene associated with litter size in small-tail Han (STH) sheep were determined. We found that BMPR1B was mainly expressed in reproduction-related tissues and was more highly expressed in the hypothalamus of polytocous than in monotocous ewes in the follicular and luteal phases. A new molecular marker was found and was negatively correlated with litter size in STH sheep. These results can provide a reference for selective sheep breeding.

The objective was to assess the genetic diversity and phylogenetic relationship of nine sheep populations. Overall, these sheep populations in the study exhibited a rich genetic diversity. The nine sheep populations can be divided into two groups. SUF and DST were clustered in one group, and GMM–BAS–BAM, HUS–STH and DOS–DOP were divided into three clusters. This clustering result is consistent with sheep breeding history. TreeMix analysis also hinted at the possible gene flow from GMM to SUF.

The expression patterns of the HPG axis-related genes in rams were analyzed using qPCR. It showed that DIO2 and KISS1 were mainly expressed in pituitary and hypothalamus in both breeds, respectively. EYA3 and GPR54 were widely expressed in both breeds, with significant differences in testis and vas deferens. We speculated that the four genes may regulate the estrous mode in different regions in rams. This is the first study to analyze the expression patterns of HPG axis-related genes in rams.

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).

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.

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.
