Short summary
Short summary
Good reproductive rates presented by the sheep show satisfactory reproductive activity during the two seasons, characterizing good adaptation to the region. The dry season seems to be a season that requires provision of an alternative feed in this critical period, which is characterized by the scarcity of rain and thus the dryness of the pastures.

Short summary
Peroxiredoxin-6 (PRDX6) is expressed in the epididymal tissue, epididymal fluid, and epididymal sperm of sheep. As the sperm mature and transit through the epididymis, the intracellular distribution of PRDX6 gradually becomes more extensive. This suggests that PRDX6 has an important role in promoting sperm maturation.

We used endometrial stromal cells of Qianbei Ma goats as our study subjects and found that N-acetylcysteine could promote the proliferation of endometrial stromal cells and increase the viability, antioxidant activity, mitochondrial membrane potential and expression of endometrial receptivity marker genes of endometrial stromal cells, which suggests that N-acetylcysteine may be beneficial in improving endometrial receptivity of goats.

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.

The current study was designed to evaluate the probable protective effect of luteolin against lipid peroxidation of ram spermatozoa membranes and kinematics during cold preservation. Results indicated that luteolin was able to improve the kinematics of spermatozoa during liquid storage. Enzymatic and total antioxidants were improved by luteolin enrichment. Luteolin did not affect the nitrosative index of stored ram spermatozoa after 72 h.

In this study, we investigated the effect of the sheep FecB gene on reproductive and productive performance by molecular biology techniques. Our results showed that the most dominant genotypes associated with lambing performance were AA and CT, with the dominant haplotype combination being AACT. In terms of body performance, the dominant genotypes were AA and CC, with the dominant haplotype combination being AACC.

Poor-quality drinking water plays a detrimental role in the suppression of calf immunity, giving rise to an increased rate of calf mortality. The present study aims to evaluate the causes of calf mortality in beef and dairy farms in relation to drinking water quality (DWQ). We could conclude that DWQ highly affects causes of calf mortality, but we cannot exclude some farm hygienic risk factors.

This study aimed to investigate the relationship between oxidation and antioxidation parameters before superovulation (SOV) treatment and embryo recovery in donor cows. The redox status of donor cows before SOV treatment affects embryo recovery, as cows with high levels of both oxidative and antioxidative status have better embryo production. This information will be useful for the selection of donor cows and subsequent treatments.

Sheep breeding is one of the leading livestock sectors in agricultural countries, including Kazakhstan. A comprehensive study of the genetic aspects of these animals will solve many issues of the effectiveness of sheep breeding. This is important for such little-studied breeds as the Kazakh meat–wool sheep breed, which are multifetal. In this study, for the first time, we characterized this breed by looking at fecundity genes and found mutations that positively affect sheep fertility.

The aim of this work was to determine the effect of the pre-mating weight (PMW) and placental characteristics on the birth weight (BW). Although prior studies have determined a relationship between BW and placental characteristics, no existing work has determined a relationship between the PMW and BW. This is also the first study in which placental surface area is used as a factor for determining the relationship between placental characteristics and BW.

There are few studies investigating the RNA-binding protein Lin28B and ovine puberty. This study focuses on understanding how its overexpression changes microRNA levels, cell proliferation, and estrogen secretion. To assess these changes, we used quantitative real-time (qRT) PCR, overexpression vectors, and ELISA. We found that Lin28B overexpression decreases let-7b and let-7g levels and increases granulosa cell proliferation and their estrogen secretion.

Short summary
Our study suggests that dietary supplementation in Barki ewes prior to mating is effective in maintaining reproductive performance. This improvement is evident through increased levels of hormonal profiles, numbers and sizes of ovarian follicles, improved conception, and lambing rates. In fact, the effects of protected fats are most pronounced when combined with hormonal treatments.
