中文摘要

The purpose of the experiment was to study whether supplying extra iron in trace minerals supplement would influence the digestibility and iron residue of hair in pigs. A total of 8 pigs were used and randomly distributed into two treatments. Treatment 1: Four pigs were fed normal iron diet in stall. Treatment 2: Four pigs were fed normal iron diet and then fed low iron diet with no extra iron supplement from trace minerals. The pigs’ back hair was cut first before experiment, a second time after two weeks’ treatment, and again after another two weeks’ treatment. Metabolic tests were conducted once during the second week and again during the fourth week of test. The diet provided for pigs was corn soybean meal. The results showed that the hair content of iron, zinc, calcium, manganese (P>0.05), and copper (P<0.05) was lower than control group with lower iron content in the diet. The digestibility of iron, zinc, calcium, and manganese was reduced when iron supplement was reduced but did not reach a significant level (P>0.05). The digestibility of copper increased, but it did not reach a significant level, either.
