1a) Limited range of activity 1a)???????
  • May affect individuals or a whole group, and
    includes ??????????,??
  • Restricted space in intensive farming systems or
    laboratory housing ????????????????
  • Close tethering ?????
  • Lameness ??
  • Increased lying time (due to lameness, disease,
    obesity or weakness) ???????(??????????????)

15
1b) Limited range of activity due to confined
housing1b) ??????????????
16
1c) Limited range of activity due to close
tethering 1c ) ?????????????
17
1d) Limited range of activity due to lameness
1d)????????????
  • Lame animals suffer as ??????,??
  • They are in pain ?
  • They do not interact normally with other herd

    from lying down for long periods
    ?????????????,???????????

  • Identify the cause???????
  • ambient temperature????????
  • stocking density?????
  • signs of disease??????

3. Huddling or shivering 3. ??????
  • Cold ?
  • Does not usually affect most animals except in
    extreme environments ????,??????????
  • Often affects very young animals ?????????

24
5. Abnormal fear or aggression towards humans
Pigs 5.?????????????
