Emerging feed markets for ruminant production in urban and peri-urban areas of Northern Ghana

Feed shortage in urban and peri-urban areas has triggered the emergence of feed markets in Northern Ghana. These markets were surveyed at three locations (Tamale, Bolgatanga, and Wa markets) to determine types and prices of feedstuffs sold across seasons; early dry (November–January), late dry (February–April), early wet (May–July), and main wet (August–October). Semi–structured questionnaire was used for data collection. Three samples of each feed type in the markets were bought from three different sellers per market in each season. The samples were oven dried to constant weight and price/kg DM of each feed determined. The total respondents were 169. Out of this number, 41% were feed sellers, 46% buyers, and 13% retailers. The feedstuffs found were crop residues (groundnut haulm and cowpea haulm), agro-industrial by-products (bran of maize, rice, and sorghum), fresh grasses (Rotteboellia cochinchinensis), and local browses (Ficus sp. and Pterocarpus erinaceous). Prices of feeds differed (P < 0.05) among markets and were higher in Bolgatanga than Tamale and Wa markets. Prices of cereal bran were not different (P > 0.05) in all seasons but that of crop residues were higher (P < 05) in early to late dry season than the wet season. Majority (90%) of respondents opined that the feed market will expand due to increasing number of livestock population in the peri-urban areas.

     

The combined effects of the provision of feed and healthcare on nutrient utilization and growth performance of sheep during the early or late dry season

An on-farm study was conducted to determine the combined effects of the provision of feed and healthcare on nutrient use and growth performance of sheep during the early or late dry season. A total of 36 smallholder sheep farmers with a flock size of ≤7 was randomly selected within each of the three administrative regions in Northern Ghana. The sheep grazed on a heterogeneous natural pasture and offered crop residues as basal diet (control) or were additionally provided with a concentrate feed plus orthodox healthcare to control diseases and pests (CH) in a completely randomized block design. The provision of orthodox healthcare included scheduled control of endo- and ecto-parasites and administration of broad-spectrum antibiotics. Data was analyzed for the fixed effects of CH, season, or CH × season using the mixed model procedure of Genstats^®. The CH regimen had no effect (P = 0.098) on intake of natural pasture but pasture intake increased (P = 0.012) during the late dry season. Sheep on the CH regime had higher DM (P = 0.026) and N (P = 0.068) digestibility and improved ADG (P = 0.001) and feed conversion efficiency (P = 0.020) than those on the control. We hypothesize that improvements in growth performance of sheep on the CH regimen could be related to availability of nutrients for growth that will otherwise have been used for repair of damaged tissues caused by gastrointestinal parasites and ticks. Sheep on the CH regimen also had a higher concentration of fecal N during the late dry season when CP concentration was relatively higher than that in the early dry season (63.2 vs 60.9 g/day DM) when CP concentration of pasture was lower.
