马胃蝇幼虫寄生于马属动物的消化道内,是危害极大的寄生虫之一,可引起寄主患马胃蝇蛆病.目前已知全世界有9种马胃蝇,中国有6种,其中新疆伊犁有4种.该病在世界范围广泛分布,呈世界性流行,马匹感染率平均60%左右.国内新疆伊犁地区马胃蝇蛆病呈多发流行,平均感染强度为每匹马带幼虫142只,严重影响了新疆伊犁养马业的健康发展.为此,文章通过查阅近些年国内外有关马胃蝇蛆病的文献资料,对马尾蝇的种类、国内外流行病学研究、致病作用和临床症状、防治措施等进行了归纳梳理,为该病的有效防控提供参考.
伊宁市奶牛场察养殖农民专业合作社采用"合作社+农户"方式,在伊犁哈萨克自治州尼勒克县、特克斯县开展伊犁鸡(乌孙山草鸡)的鸡蛋收购、孵化、育雏、放养、肉鸡和鸡蛋的回收与销售经营,取得了较好的经济效益.对伊犁鸡(乌孙山草鸡)的养殖技术和经济效益进行了介绍,以期为大家提供借鉴.
试验从伊犁河谷采集了6个试验点的自制酸马奶样品,检测其酸度和微生物组成,并从中分离酵母菌,对其进行属的鉴定.试验结果表明,6个酸马奶样品的酸度范围为160.80~284.20°T,平均值为(221.67±51.38)°T;6个酸马奶样品中微生物组成乳酸菌数比酵母菌数高出一个对数级;6个酸马奶样品分离得到10株酵母菌,归为4个属.另外,在本实验室条件下,筛选出3株酵母菌,并与乳酸菌混合发酵制作酸马奶,在发酵过程中测定酸度变化,试验结果表明,酸度在发酵过程中逐渐上升,3株酵母菌及其组合的发酵能力各有不同.

Rectal B-scan has advantages in determination of estrus and early diagnosis of pregnancy in horses.In order to help more people working in horse breeding to understand this application of B-scan,the present author has collected many typical B-scan images in the past years of work and attempts here to elaborate on the method of rectal palpation by B-scan specifically used in horse breeding practice.The selected B-scan images included those of bladder,uterus,cornua uteri and ovary of the studied animals,all being with detailed description.
