Productive performance and parasitological control of kids supplemented with umbu fruits (Spondias tuberosa Arruda)

Summary Native fruits from Caatinga vegetation can be an important alternative to improve the productive performance of kids in the semi-arid region of Brazil. This work aimed to evaluate the effect of supplementation with Umbuzeiro fruits in natura over the weight gain and anthelmintic control of kids kept in Buffel grass pasture in the semi-arid zone of Pernambuco, Brazil. Twenty-four castrated, crossbreed kids were allocated into three treatments: 1) Control (n = 8) fed exclusively with Buffel grass; 2) Umbu 1x (n = 8) fed with fruits once a week and 3) Umbu 3x (n = 8) fed with fruits for three times a week. The following parameters were evaluated: variation of body weight, faecal egg counts (FEC) and coproculture. Overall, the average consumption of Umbu fruits in natura was 1.48 kg/animal/day, which corresponded to 133.5 g daily dry matter intake (DMI/animal/day). There were no significant difference (P>0.05) for any parameters evaluated. During the experimental period, the overall daily weight gain was variable between 108.75 to 116.70 g/animal/day and the average FEC was 436 eggs. In the present study, the goat kids supplemented with fresh umbu fruits showed a good productive performance, however the supplementation with umbu did not control the infestation of gastrointestinal nematodes in kids.

摘要：巴西半干旱地区的卡廷加（Caatinga）植被原生本土果实，可作为提升当地山羊羔生产性能的重要替代方案。本研究旨在评估在巴西佩南布哥（Pernambuco）州半干旱区域的臂形草（Buffel grass）牧场中饲养的山羊羔，补饲鲜态乌姆布泽罗（Umbuzeiro）果实对其增重与驱虫效果的影响。本试验将24只去势杂交山羊羔随机分为3个处理组：1）对照组（n=8），仅饲喂臂形草；2）乌姆布泽罗1次组（Umbu 1x，n=8），每周补饲果实1次；3）乌姆布泽罗3次组（Umbu 3x，n=8），每周补饲果实3次。本试验评估的指标包括：体重变化、粪便虫卵计数（FEC）以及粪便培养。整体来看，鲜态乌姆布泽罗果实的平均采食量为1.48 kg/只·天，对应干物质采食量（DMI）为133.5 g/只·天。所有评估指标均未出现显著差异（P>0.05）。试验期间，整体日增重波动范围为108.75~116.70 g/只·天，平均粪便虫卵计数为436枚。本研究结果显示，补饲鲜态乌姆布泽罗果实的山羊羔表现出良好的生产性能，但乌姆布泽罗果实补饲并未对山羊羔的胃肠道线虫感染起到防控作用。
