The potential of reproductive technologies in breeding smallholder cattle populations in Zimbabwe

Abstract

Cattle are critical to most smallholder agricultural livelihoods in Sub-Saharan Africa. A study was carried out to assess breed and trait preferences, breeding practices, application and potential adoption of novel reproductive technologies by smallholder cattle farmers in four districts of Zimbabwe. The study revealed that famers are subsistence oriented and follow a resource driven production system. Herd size averaged 7.5±6.42, with dominance of indigenous breeds and their crosses, open communal breeding and non-existence of reproductive technology application. The major challenges faced include reproductive and tick-borne diseases, dry season feed shortage, and poor access to affordable good quality bulls. Brahman, Mashona, Afrikaner and Tuli were the most preferred breeds for their hardiness, fertility, reproductive efficiency and draught performance attributes. Low reproductive efficiency was revealed by long bull retention periods (>5 years), long calving intervals (>18 months), low pregnancy rates (41% of cows) and high ages at first calving (34 months). Farmers indicated moderate knowledge of artificial insemination and keen interest in using this technology with semen frozen from locally bred, indigenous sires to improve their herds. There is therefore both need and potential for the application of assisted reproduction techniques for improved genetic gain, performance and reduced inbreeding in smallholder cattle herds.
