Modern poultry development in the USSR is actually development for the basis from commercial development and two-ways specialization, i.e. egg and you may animal meat production.
Throughout the socialized industry the typical yearly egg yield from hens enhanced out of 130 into the 1964 to help you 226 back in 1984. In identical period the entire egg manufacturing increased away from 29 to help you 73 thousand billion. Quantities of breeding chickens were 230 912 000 from inside the 1980 given that up against 174 758 000 for the 1975 – a rise away from 31%.
Having eggs creation extremely chickens is about three- or five-range crosses predicated on brought in grandparental lines of your after the: Shaver – 288, 292, 444, Evribreed -Highsex Light, Highsex Brownish while others. When you look at the same day the fresh numbers of eggs-sort of Russian White chickens decreased – they were six.8-fold smaller from inside the 1980 weighed against 1975.
thirteen. Residential FOWL
Having meat production the present carries would be the four-range crosses Broiler-six and you may Broiler-compact-8 that happen to be molded off Dutch lines of one’s Evribreed business. The fresh new alive weight regarding eight-week-dated broilers was 1.seven kilogram, which have 2.8 kilogram away from supply getting consumed for each and every kg away from gain.
Full fowl meat manufacturing are 2.2 mil tonnes back in 1984, we.elizabeth. 3 x to inside 1965 (700 100000 t). Your food Programme of USSR envisages production of step three.4-step 3.six meters t off fowl chicken when you look at the 1990. Special attention has been paid back on the reassurance from fowl breeding on individual plots of cumulative growers.
Although not, industrialization off chicken breeding have resulted in a serious reduced how many types. Nearly all of them have lost their energetic value and are managed merely because a genetic resource during the lookup centres by inexperienced breeders.
That it section relates to neighborhood, old and you may this new breeds and communities on the Soviet Partnership (look for Desk 13.1). The bulk of them are dual-goal types that have a reduced efficiency which aren’t utilized by the fresh chicken globe. But not, they features many rewarding physical features – resistance to condition and you can sharp alter regarding environment temperatures; higher reproductive rate below industrial conditions; highest chicken palatability.
The newest traces which happen to be popular on chicken world defectively you need hereditary range from the significantly more than properties. Based on regional and you may rare populations on the Soviet Commitment brand new breed groups and extremely energetic contours and crosses was are establish which happen to be adapted with the particular climatic zones in the country.
Egg Types Barred-AND-SPECKLED LEGHORN (Polosato-pestraya leggorn)
The brand new man-made society are produced throughout 1976-84 on Ail-Commitment Browse Institute regarding Ranch Creature Reproduction and Genes from the crossing Light Leghorn people of your C collection of get across Shaver 288 and you will hens regarding an experimental distinctive line of Black colored Speckled Australorps. The fresh family genes accountable for the colour from Leghorn plumage – We, Sp, w – as well as their alleles into the Australorps – i, sp, W – were used since markers which will make hereditary assortment about the brand new line.
The first specimens (n=30) out-of chickens homozygous for the color family genes have been built in 1978 of the inter se reproduction out of white hybrids (F2) that have step 3/4 from Leghorn genetics. That they had a noticable dosage effect of gene B about Leghorn intercourse chromosome. The male chickens (BB spsp) had light plumage which have outlines away from barring and ladies chickens (B-spsp) was banned-and-mottled having white off.
In the 1st phase out-of breeding the latest stock off Banned-and-Speckled Leghorns designated just 200-250 head. The bulk of them was indeed heterozygotes (Ii Spsp and ii Spsp) (n=l 500) having annual eggs production of 230 egg weighing 56-57 g. It was with strict choice among females (50% intensity) getting egg pounds, conformation and maturity of men (choice strength 10%) as crosses between around Omaha dating services ten outlines. Certainly men birds part of the alternatives criteria was conformation, lbs and top-notch eggs of its lady moms and dads, also to a much decreased the amount the eggs production of lady moms and dads.
