摘要

本文旨在综述繁殖失败对水牛系统盈利能力的经济影响,以及不同因素对水牛繁殖性能的影响。此外,还概述了各种非激素替代品,以提高生殖性能。水牛的最佳繁殖效率意味着产仔至受孕间隔约为90天,达到产仔间隔400天,产仔间隔较长会对盈利能力产生负面影响。生殖效率是遗传和非遗传因素相互作用的结果,必须优先通过分析生殖信息来识别这些因素。尽管每个因素的影响程度可能更大或更小,这取决于每个牛群的条件,但一些因素,如营养、产奶量、身体状况评分、负能量平衡、产次、公牛出现、发情强度低和季节,都可以被视为高影响因素。并非所有因素在农场中都是常见的;因此,每个农场都必须实施一个识别、控制和预防生殖问题的计划,特别是在哺乳早期,以防止长时间的麻醉;当使用人工授精时,要在发情期开始的正确时间进行,以提高生育能力。

Reproductive Performance of Water Buffalo Cows: A Review of Affecting Factors
This article aims to review both the economic impact of reproductive failures on the profitability of water buffalo systems and the effect of different factors on the reproductive performance of water buffaloes. Besides, an overview of various non-hormonal alternatives to improve reproductive performance is made. The optimal reproductive efficiency in water buffaloes implies calving to conception interval around 90 days to reach a calving interval of 400 days, with longer calving intervals having a negative impact on profitability. Reproductive efficiency is the consequence of the interaction of genetic and non-genetic factors, and the recognition of these factors by analyzing the reproductive information must be a priority. Although each factor's impact can be of greater or lesser magnitude depending on the conditions of each herd, some factors like nutrition, milk yield, body condition score, negative energy balance, parity, bull presence, low estrus intensity, and season can be considered high-impact factors. Not all factors are common among farms; therefore each farm must implement a program for the identification, control, and prevention of reproductive problems, especially during early lactation, to prevent a long anestrus; and when artificial insemination is used, so that it is done at the correct time with respect to the beginning of estrus to enhance fertility.
