Abstract
Изобретение относитс к сельскому хоз йству . Целью изобретени вл етс более ранний отбор и повышение точности оценки. Дл селекции отбирают молодок с учетом оценки их будущей продуктивности. Оценку продуктивности осуществл ют по двум показател м - возрасту снесени первого йца молодкой с учетом ее живой массы. Дл селекции отбирают молодок, снесщих первое йцо в возрасте 140-150 дней и имеющих при этом живую массу, составл ющую 75-90% от массы взрослых кур селекционируемой линии. 1 табл.This invention relates to agriculture. The aim of the invention is an earlier selection and an increase in the accuracy of the assessment. For selection, pullets are selected taking into account the assessment of their future productivity. Evaluation of productivity is carried out by two indicators - the age of the first egg carried by the pullet, taking into account its live weight. For breeding, pullets are selected that carry the first egg at the age of 140-150 days and have a live weight of 75-90% of the weight of adult chickens of the breeding line. 1 tab.

Изобретение относитс к сельскому хоз йству и может быть использовано в племенной работе в птицеводстве.The invention relates to agriculture and can be used in breeding work in the poultry industry.
Целью изобретени вл етс повышение йценоскости кур и более раннего отбора. The aim of the invention is to increase the chicken production rate and earlier selection.
Пример. Молодки линии М9 кросса Старт в возрасте 17 недель в количестве 261 головы были посажены в индивидуальные клетки. У них учитывали йценоскость до 68-недельного возраста, проводили взвешивание кур при снесении первого йца иExample. Juveniles of the M9 Cross Start line at the age of 17 weeks in the amount of 261 heads were planted in individual cells. They took into account the yen-rate up to 68 weeks of age, weighed chickens when the first bird and
иц в 40-недельном возрасте. В этом возрасте была проведена оценка кур двум способами . По прототипу отбирали кур с йценоскостью за 40 недель жизни выше 82 иц и массой йца в этом же возрасте выше 53,5 г. По изобретению кур отбирали дл селекции по возрасту снесени первого йца 140-150 дней и живой массе при этом 1500-1800 г.herts at 40 weeks of age. At this age, chickens were evaluated in two ways. According to the prototype, chickens with a yield of 40 weeks of life above 82 eggs and a egg weight at the same age above 53.5 g were selected. According to the invention, chickens were selected for selection by age of the first egg for 140-150 days and live weight at the same time 1500-1800 g .

Способ позвол ет повысить йценоскость селекционируемой птицы за 68 недель жизни на 1,7% при проведении отбора в более раннем возрасте в 140-150 дней вместо 210 дней. В результате использование племенной птицы возрастает на 5-6 недель. The method allows to increase the yielding rate of the selected bird for 68 weeks of life by 1.7% when conducting selection at an earlier age of 140-150 days instead of 210 days. As a result, the use of breeding birds increases by 5-6 weeks.
