Abstract
The productivity of the progeny of Stavropol sheep from parental pairs of different ages was studied. To obtain offspring, 4 groups of parent pairs of 1.5- and 2.5-year-olds were formed. Offspring from pairs of “1.5-year-old uterus × 2.5-year-old sheep”, “2.5-yearold uterus × 2.5-year-old sheep” prevailed in live weight over analogues of “1.5-year-old uterus × 1.5-year-old sheep”, “2.5-year-old uterus × 1.5-year-old sheep” by 8.23; 3.23% and 6.29; 1.38% (p ≥ 0.99). Young animals from pairs of “2.5-year-old uterus × 1.5-yearold sheep” outperformed animals from combinations of “1.5-year-old uterus × 1.5-yearold sheep”, “2.5-year-old uterus × 1.5-year-old sheep”, “2.5-year-old uterus × 2.5-yearold sheep” by 5.26% (p ≥ 0,95), 3,77%, 2,08% (p ≥ 0.95), 4.04% (p ≥ 0.95), 2.39% and 2.8%. Young animals from pairs of “2.5-year-old uterus × 1.5-year-old sheep” had a higher wool yield than from pairs of “1.5-year-old uterus × 1.5-year-old sheep”, “1.5-year-old uterus × 2.5-year-old sheep”, “2.5-year-old uterus × 2.5-year-old sheep”, by 0.1%, 0.8% and 1.2% (p < 0.95). In the Volga region, for the productive use of Stavropol sheep, it is advisable to combine parental pairs of “1.5-year-old uterus × 2.5-year-old sheep” and “2.5-year-old uterus × 2.5-year-old sheep”.
