The structure of the flock is the proportion of sheep of various genders, ages, and uses in the flock. A sheep with a proper proportion and a reasonable structure has higher productivity, reproduction rate and commodity rate. There are certain differences in the structure of the sheep in different production directions.
(1) Special breeding sheep breeding households sell sheep for the purpose of management, so the ewes should account for 60% to 65% of the total number of sheep, elder ewes should not exceed 5%, and reserve ewes (1 to 1.5). The age of about 15%. When using natural mating, adult rams should account for 3%, reserve rams 1% to 2%, and rams should not exceed 10%. If artificial insemination is applied, the number of rams can be reduced and the proportion of ewes breeding can be increased.
(2) For sheep-raising households, which mainly produce wool and milk, the age of breeding ewes may be slightly larger to extend the useful life and increase the production of commodities. Cashmere production is generally higher for woolly sheep, angora goats, cashmere goats, and non-species, and the proportion of woollen cashmere production is generally increased to increase the production of plush. For high-yielding dairy goats, the age of elimination can be appropriately extended, and the proportion of females to be bred should be about 60%, and the reserve ewes should account for about 20%.
(3) In order to increase the slaughter rate and accelerate the turnover of sheep, the proportion of ewes breeding should account for more than 70% of the specialized households that produce mutton, among which the majority of the ewes should be in the prime. Lambs are slaughtered as soon as possible after they are produced. Do not exceed 1 year old. It is better to produce fat lambs aged 6 to 8 months. Early slaughter, ewes can be estrus early mating, for three years to produce three children, and even two births a year, to increase the slaughter rate of sheep.
(4) In order to breed as many lambs as possible, the proportion of females breeding sheep may be increased to more than 80%, and in addition to retaining about 15% of the female lambs to supplement breeding ewes Outside the flock, lambs are slaughtered for 1 to 3 days after birth to produce lambs, or slaughtered at about 1 month of age to exfoliate the two furs without having to keep the fries.
