A survey on live- stock and milk production characteristics of peri-urban agropastoral dairying in Ghana

Abstract

A survey was conducted in five districts on the Accra plains to characterize the peri-urban dairy production system. Results from the survey indicated that farmers were keeping cattle, sheep, goats, and poultry (Guinea fowl, turkey, chicken, and duck), cattle being the only species milked. The mean flock size was 73.6 TLU with a coefficient of variation of 103 per cent. The average cattle herd size was 133. Farmers made limited use of agro-industrial by-products. Cultivation of pastures, improved fodder, and multipurpose trees was non-existent, and neither was any system of cut and carry practised. The use of concentrate and protein supplementation was also negligible. The mean length of the dry season was 5.2 1 0.7 months. Offtake was low at 8.9 per cent per annum. Replacement and calving rates were 0.7 and 0.67, respectively. The mean age at first calving and calving interval were 36 and 14.4 months, respectively. The mean lactation length was 8.5 months. There were no crossbreds of the type 'exotic W local'. The Sanga was the predominant breed of cattle and constituted over 76 per cent of cattle kept on the Accra plains. Feeding of calves was by suckling residual milk from dams after partial milking. Calves were allowed to suckle until the cow was nearly dry, leading to a long mean calf weaning age of 8.4 months. Cows were milked once daily usually in the mornings. The mean daily partial milk yield per cow was 1.55 1 0.22 l. Mean partial annual milk yield per farm was 10,040 1 2952 l. It was concluded that the system required substantial transfer of improved technologies to increase milk production. \r Ghana Jnl.agric. Sci Vol.32(1), 1999: 53-58
