Efeitos da suplementação com fósforo em caprinos no semiárido do nordeste brasileiro

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 Brazilian semiarid region.
