摘要

在津巴布韦独立后土地改革的空间土地利用产物安置区内,对牛的表现进行了为期两年的监测。在20个村庄重新安置计划的3个选定村庄中,共有30名农民每人至少拥有5头牛。每个月对参与的村庄牧场在不同地貌覆盖等级下的生物量产量进行评估。在两年的时间里,研究人员监测了在农民管理条件下的牛的繁殖(产犊率和频率、再产犊率)和退出记录(销售、屠宰、死亡、交换和买入)。分析了牛重、退出和繁殖记录作为性能指标。研究发现,低至中等产犊率(25-40%)和低再产犊率(16 -26%),营养减少和低采食量(7.3%至18.7%)是牛生产性能的主要障碍。月牛体重随有效放牧生物量的变化而波动,在旱季(9 ~ 12月)最低。母牛和小母牛比阉牛更容易受到营养减少的影响。该研究的结论是,在适当的兽医实践的配合下,改善营养、增加摄取和可能在安置地区利用公牛是在中短期内提高牛生产性能的适当行动。

A synopsis of cattle performance in Zimbabwe’s ‘initial’ resettlement areas after land reforms and redistribution
Cattle performance was monitored over a two year period in a resettlement area, a spatial land-use product of Zimbabwe’s land reforms post-independence. A total of 30 farmers each owning at least 5 cattle in 3 selected villages of a 20 village resettlement scheme were targeted for the study. Participating village rangelands were assessed monthly for biomass yield in different physiognomic cover classes. Cattle in the study were monitored over a two year period for reproduction (calving rate and frequency, re-calving rates) and exit records (sales, slaughters, deaths, exchange, and buy-in) under farmer management conditions. Cattle weights, exit and reproduction records were analyzed as measures of performance. The study found low to medium calving rates (25-40%) and low re-calving rates (16 -26%), with diminished nutrition and low off-take (7.3% to 18.7%) as major impediments to cattle performance. Monthly cattle weights fluctuated with quantity of available grazing biomass, and were lowest during the dry months (September to December). Cows and heifers were affected more by diminished nutrition than steers. The study concluded that improving nutrition, increasing off-take and possibly availing bulls in resettlement areas were appropriate actions to increase cattle performance in the short to medium term, complimented by adequate veterinary practices.
