Повышение качества ремонтного молодняка гусей

Повышение качества ремонтного молодняка гусей

Abstract

Цель работы — повышение качества ремонтного молодняка гусей при скрещивании белой венгерской и кубанской пород. Для достижения данной цели были поставлены задачи: произвести оценку ремонтного молодняка гусей различных генотипов и рассчитать экономическую эффективность результатов проведенных исследований. Исследования проводили в условиях ООО «Башкирская птица» Благоварского района Республики Башкортостан в 2009-2012 гг. Для исследований использовали гусей белой венгерской, кубанской пород и их помесей. Для выявления лучших сочетающихся линий в исследованиях использовали реципрокное скрещивание. С целью оценки качества ремонтного молодняка гусей различных генотипов по принципу аналогов были сформированы 4 группы по 160 гол. суточных гусят. Первая группа была укомплектована гусятами белой венгерской породы, вторая — кубанской, третья — помесными гусятами, полученными путем скрещивания белых венгерских гусаков с кубанскими гусынями, и четвертая — помесями кубанских гусаков и белых венгерских гусынь. Исследования проводили в течение 240 дней. Условия выращивания, содержания и кормления птицы соответствовали методическим рекомендациям ВНИТИП с учетом их породных особенностей. По результатам исследований установлено, что помесный молодняк, полученный при скрещивании гусаков белой венгерской с гусынями кубанской породы, превосходит своих сверстников по сохранности на 0,6-3,8%, живой массе — на 2,2-19,5% (р

The research purpose was to improve the quality of replacement geese by crossing White Hungarian and Kuban geese. The objectives included the evaluation of replacement flock of various genotypes and cost-effectiveness calculation. The studies were conducted at OOO "Bashkirskaya ptitsa" company of the Republic of Bashkortostan in 2009-2012. The geese of White Hungarian, Kuban breeds and their crossbreeds were studied. To identify the best combination lines, a reciprocal crossing was performed. To evaluate the quality of replacement flock of various genotypes, 4 groups of 160 daily goslings were formed. Group 1 included White Hungarian goslings, Group 2 — Kuban goslings, Group 3 crossbreeds obtained by crossing White Hungarian ganders with Kuban geese, and Group 4 — crossbreeds of Kuban ganders and White Hungarian geese. The studies lasted for 240 days. It was found that the young crossbreeds obtained by crossing White Hungarian ganders with Kuban geese outperformed the contemporaries in terms of livability (by 0.6-3.8%), live weight (by 2.2-19.5%) (p
