摘 要:将乌苏里貉按自然养殖户分组,对比分析不同饲养管理水平与养殖效益的相关性。结果表明,提高育成貉饲料中蛋白质成份给量,准确把握母貉发情时间并适时配种,搞好母貉妊娠期饲养管理,把好母貉产仔关,每只育成貉经济效益多收入65元;平均多产仔2只;产仔成活率高12个百分点。

Abstract:The correlation of different raising management standards and breeding effiency was compared and analyzed by grouping the raccoon dog on the basis of natural culturing family. The result showed: by the way of increasing the feeding amount of protein ingredient for ikunair raccoon dog, grasping accurately the estrus period of female raccoon and timely molting. Doing well in raising management with the gestation of female raccoon and carefully checking on the litter offer male raccoon, then the economize efficiency will be increased 65 RMB for every ikunair raccoon dog; litter increased 2 heads in average, survival rate for litter increased by 12%.
Key words: raccoon dog;raising management ;economic efficiency;breeding technique
乌苏里貉养殖效益的关键是皮张销售价格,毛皮的质量是销售价格的重要保证。所谓貉皮的质量主要与貉皮长度、貉皮的绒密度、柔软度以及毛色等因素相关[1]。
要保证毛皮动物的养殖效益,饲养数量也是一个重要因素。因此,乌苏里貉的繁殖则成为养殖业发展中的重要环节。而与繁殖相关的重要内容是母貉的发情鉴定、适时配种、妊娠期饲养管理以及产后仔貉的护理等。
近几年来,伴随着天津经济发展,劳动力的价格不断升高,不少传统养殖业的存栏数呈下滑的趋势,尤其是养禽业更是如此。蛋、肉鸡存栏数较前5年明显下降,并呈不断向劳动力比较便宜的山东、河北等地区转移的趋势,与传统养殖业的发展态势相反,天津的毛皮动物养殖正悄然兴起,天津地区的气候和地理位置都非常适宜饲养皮毛动物,太炎热地区会导致毛皮动物底绒稀疏,使毛皮质量下降,严重影响销售价格,寒冷地区虽然底绒令人满意,但寒冷地区养殖的毛皮动物饲料消耗大(大部分饲料用于维持体温),造成养殖成本升高。……
