Resumo:
Essential trace minerals are necessary nutrients for normal function of the tissues and processes intimately related to reproduction. A dietary deficiency in essential trace minerals is manifested either as the inability to establish or maintain pregnancy or a reduction in the size of the litter (Hurley and Keen 1987). The mechanism involving the absorption and subsequent utilization of essential trace minerals by animals remains unclear, making it difficult to estimate the dietary requirements for trace minerals. In addition, the chemical form of dietary trace minerals is as important as the quantity. Chelated forms of trace minerals have a greater potential for absorption than those in organic form (Lowe et al. 1994a). Mirando et al. (1993) showed that sows provided with the chelated forms of zinc (Zn), manganese (Mn) and copper (Cu) in their diet had a greater number of live fetuses 30 d after breeding than those given these trace minerals solely from inorganic sources.
This study was conducted to determine if providing dietary Zn, Cu and Mn in the chelated form affects reproductive and health characteristics of bitches and their pups
