Assenting to , Death and That of the Other, achieve this. Authorities are increasingly tightening controls on pollution of water and air from pig units. The recent trend for a greater proportion of the national herd to be kept on holdings with adequate land for manure disposal is expected to continue.GUISE 发表于 2025-3-23 18:42:07
Philosophical Theology of Vocation,per and zinc were also determined by 0.5 N, HN03 and by nitroperchloric digestion. From our pot and field experiments we believe it is dangerous to incorporate 500 kg/ha Cu or Zn into Finisterian soils for cultures such as Italian rye-grass, maize. winter-wheat, barley (≥ 120 ppm Cu or Zn by EDTA meGLIDE 发表于 2025-3-23 23:56:30

Physiological Aspects of Copper in Pig Dietss on which Cu compounds have been used in the various experiments and how the macro- as well as the micro-mineral supply of the feed ration is balanced as Cu interaction with other minerals on the absorbative level is of unique importance in the intermediary metabolism of Cu.权宜之计 发表于 2025-3-25 02:23:44
