Respiratory Diseases(628) These are a major problem on many farms today and they usually appear at predictable times that coincide with an increased demand for energy together with a change in the environment. Of all the factors highlighted in Fig.14-5 the following three will always be important if there is a disease problem;
- An incorrect diet during and for 7 to 10 days after pig movement that creates a negative energy situation.
- A change in environmental temperatures associated with movement that creates negative energy state.
- Exposure to infection and the development of disease at the same time.
- Identify the time when disease first becomes evident.
- Note when nutritional changes take place. When pigs move from one house to another there is often a drop in the nutrient density of the diet. This also coincides with a drop in intake for the first 2 to 7 days.
- This reduced feed intake and change can result in catabolism and the pig dropping below the LCT.
- Maintain high energy diets at critical times. Do not change the feed for at least 5 days when pigs move from one house to another.
- Provide adequate water at all times. Look at the type of nipple drinkers, their availability and accessibility to the pig, particularly when it moves from one house to another.
- Look at the methods of feeding. Are there any features of design or feeder placement that inhibit access to the feed.
- Is there sufficient hopper space.
- Make sure there are adequate levels of vitamin E in the diet. Add an extra 50-100 gm to the tonne if there is a disease problem.
