STUDIES OF CATTLE, HORSES AND PIGS KEPT I N LOCATIONS WITH GEOPATHOGENIC EFFECTS AND THE INFLUENCE OF A PHOTON MAT EMBEDDED IN A SLAB .3. HEALTH AND DISEASE OF COWS AND THEIR FERTILITY AND CONCLUSIONS

There were no consistent geopathogenic effects on the cows, possibly b ecause of the ranges in age and breed and the fact that faints were se lected for sub-optimal fertility in the cows and not for geopathogenic effects. The use of the photon mat embedded in a slab produced benefi cial effects in the fattening steels and cows; weight gain improved in the steers as did the fertility of cows and some of the blood paramet ers. The results are considered to be important for the welfare and ec onomic aspects of animal husbandry.
