To evaluate the effect of phosphorus supplementation for goats grazing for the semiarid region, one group of 16 recently weaned Moxotó goats was supplemented with a mineral supplement containing Na, Cl, Zn, Cu, Se, Co, and P during 240 days. Another similar group was supplemented with a similar mineral supplement without P. The mean daily consumption of supplement by animal was of 7.09±2.77g and 7.67±3.14g for the groups with and without P, respectively. The mean weight gain of the P supplemented group (45.20±5.56g) was significantly higher (P<0.05) than the non-supplemented group (40.03±2.80g). The average total P in soil was 30.8mg/kg and in the pasture 0.13% in dry matter. These results demonstrate the occurrence of P deficiency in some areas of the... |
