Abstract
These studies were carried out at the Research farm of National Animal Production Research Institute, Shika to investigate the effect of management practices on the milk yield and live weight changes of grazing Red Sokoto and Sahelian goats as influenced by supplementation with groundnut haulms and concentrate. Experiment 1 involved 5 Red Sokoto goats with average weight of 27.3 ± 1.37Kg kept either on-farm or on-station and fed groundnut haulms or concentrate. The result showed that management had significant effect on average daily gain (ADG) of kid at 146.7± 0.62g (P<0.01) and dam weight loss of -24.7±1.26g (P<0.05). Milk yield was less sustained on farm. Week of lactation affected milk yield ( P<0.01). In experiment 2, five goats of each of Red Sokoto or Sahelian breeds were randomly assigned to either groundnut haulms or concentrate as supplement. The results, showed that there were significant effect of breed (P<0.0001) and week (P<0.001) on milk yield, mean dam and kid weights respectively. The Red Sokoto dams had higher milk yield (414.1±47.19ml) than the Sahelian dams (203.2±46.61ml). Similarly, breed and type of supplementation fed showed significant difference (P<0.005) on milk yield. Red Sokoto dams fed concentrate produced more milk (555.1±64.92ml) than Sahelian fed concentrate (295.2±69.51ml) or groundnut haulms (111.4±69.51ml). Also in comparing the kid growth performance between on-farm and on-station, The average daily gain of kids was 112.9g± 0.53 was significantly influenced by week of lactation, while dam lost an average of 11.7±0.65g indicating that kids managed on farm were heavier than those on station. However dam on-station lost less weight than those on-farms. The result showed that supplementation of grazing does with diets of protein source irrespective of management will improve milk yield and that heavier dams supported better kid growth.Keywords: On-farm, On-station, Performance, Red Sokoto, Sahelian..
