新生犊牛腹泻是引起犊牛死亡最常见、最主要的原因之一,严重影响着养殖企业的经济效益.腹泻可导致严重的脱水、酸中毒、电解质紊乱等,准确判断犊牛脱水程度、尽早采取补液疗法是最重要的治疗措施,非甾体抗炎药的使用可以提高治疗效果,改善犊牛福利.

母猪产仔数的多少和仔猪成活率的高低决定了养猪场获得经济效益的多少,只有努力提高这两个指标,才能在日益激烈的竞争中获得更强的核心竞争力.本文从多个角度出发,结合影响母猪产仔数和仔猪成活率的各大因素提供相应的建议,以期能为广大养殖户提供一定的参考.

在规模化种禽养殖过程中,雏鸡的抵抗力差及机体机能不完善,成鸡生产性能低下,种蛋的受精率达不到标准,给养殖户(场)造成了极大的经济损失.所以,如何提高雏鸡成活率、成鸡的生产性能、种蛋的受精率就显得尤为重要.基于此,就如何保持种禽种群健康,提高种禽产蛋率进行探讨.

人工授精因为优点众多而被广泛采用,但在养羊过程中,依然有很多人因为不熟悉该技术而不能使这一技术得到良好的推广.本文对该技术的流程进行详细分解,为广大从业人员提供技术参考.

Heat stress during late gestation has profound effects on cows during the pre- and postpartum periods. In addition to impaired immune function during the transition period, heat stress during the dry period adversely affects mammary gland development before parturition and exerts residual effects on metabolism in early lactation and subsequent lactational performance. Maternal heat stress in late gestation also compromises placental development and fetal growth and negatively affects the immune competence of the offspring. These observations suggest the importance of heat stress abatement as an easily implemented method for managers to improve dry cow performance and calf health and growth.
