Swine rearing and pork production has recently attracted the growing interest of Ghanaian farmers who seek diversification of enterprises and existing farmers looking for alternatives following a period of low profitability. Piggery was established to combine science and technology to generate innovations for anyone seeking to establish a new pig production enterprise. Results show that since 2008 to 2013, pork prices in Ghana rose rapidly between 115-120%. Also the rate of returns was higher at 43.62% compared to bank interested rate. Feed, as a percentage of total costs, were minimised from 70% to 55% with integrated lactobacillus brewer spent malt as supplement to formulated feed. The piggery project was highly successful and invested capital was recouped within two years of project take-off. Collaborating with other farms, organisations and entrepreneurs, a lot of research innovations in the area of improving feed cost, animal nutrition, waste management practices, and breeding have been generated and shared with both small and large-holder pig farmers. In all aspect of the farm management, results achieved so far especially with pork carcass quality and profit margins are encouraging which have led to the expansion of the piggery project. 展开更多
