Abstract

Even with a high vitamin E offer, Se deficiency (less than 38 micrograms/kg DM of the ration) led to a 33% lower conception rate (P less than 0.05) in goats and to a greater than 50% lower number of kids on the 91st day of life. The Se deficiency reduced the milk production significantly by 23% during the first 56 days of lactation, the milk fat production by 11% and the milk protein production by 12%.

摘要

即使提供了高剂量的维生素E，缺硒（日粮中低于38微克/千克干物质）仍导致山羊受孕率降低33%（P<0.05），并且在出生后第91天的羔羊数量减少超过50%。缺硒使泌乳期前56天的产奶量显著降低23%，乳脂肪产量降低11%，乳蛋白产量降低12%。
