母猪无乳综合征(MMA)新见解

母猪无乳综合征(MMA)是母猪乳腺炎(Mastitis)、子宫炎(Metritis)和无乳症(Agalactia)的简称,是由多种原因引起的母猪产后泌乳量逐渐减少甚至是完全无乳,以致于哺乳仔猪乳汁摄入量不足,严重影响到仔猪的生长发育。MMA在猪场中经常发生,尤其是在炎热的夏秋季节多发,母猪一旦发生MMA,就会影响到仔猪的成活率,从而给猪场带来经济损失。许多饲养母猪的猪场对MMA都比较熟悉,有研究表明,规模猪场中哺乳仔猪死亡因素的50%都与MMA有关。那么,是什么原因导致了母猪MMA问题?MMA的发生现状又如何?一旦发生,猪场该如何应对?怎么样进行防治?本篇文章主要介绍了英国颇为高产(已发表近3000篇关于养猪的文章)的养猪专栏作家John Gadd,结合他本人过去几十年来在世界各地猪场的宝贵经历,写成的介绍母猪MMA的最新文章。

New light on mastitis-metritis-agalactia(MMA)syndrome of sows

Recommendation:“MMA”is the abbreviation of mastitis,metritis and agalactia.As we know,the combined disorder known as MMA syndrome is comprised of three separate but often associated conditions.It is caused by many reasons,the amount of postpartum milk in sows is gradually reduced or even completely milkless,so that the intake of milk in suckling piglets is insufficient,which seriously affects the growth of piglets.MMA occurs frequently in pig farms,especially in the hot summer and autumn seasons.Once MMA occurs in sows,it will affect the survival rate of piglets and thus bring economic losses to pig farms.Many pig farms with sows are familiar with MMA.Studies have shown that 50%of deaths of piglets in scale pig farms are associated with MMA.So,what causes MMA?What's the status quo of it?Once that happens,what to do and how to do it to make the sows live better?How to prevent it?This article shed new light on the sows with MMA syndrome written by John Gadd,a swine columnist in England who is quite prolific(nearly 3000 articles or research papers have been published),combined with his own valuable experience around the world over the past few decades.
