1.7. Read the text and mark the correct letter (a, b, c or d) for the paragraphs:

A. In young stock vitamins A and D are furnished with choice, green-coloured hay.

B. Abundance of vitamin A in suckling animals is furnished by milk.

C. Poultry will need particularly liberal amounts of riboflavin.

D. Under winter conditions young stock will result in rickets because of lack of vitamin D in their ration.

1. Suckling animals will receive plenty of vitamin A in the milk if their dams are fed suitable rations. When they are weaned care must be taken that sufficient of this vitamin is furnished by well-cured hay, good pasture or other green feed, or by yellow corn.

2. In the case of calves changed from whole milk to skim-milk or milk substitutes at an early age it is especially important that they are furnished with choice, green-coloured hay to provide both vitamin A and vitamin D. Young stock on pasture will not suffer from a lack of vitamin D, because of the effect of the ultra-violet rays in sunlight.

3. Under winter conditions, however, young pigs are often severely crippled or even paralysed by rickets, caused by a lack of this vitamin. Also calves often suffer from rickets, and they may be stunted and badly deformed as a result. These conditions can usually be entirely prevented by the use of well-cured legume hay. Lambs rarely have rickets probably because they eat much hay, and all good shepherds make a special effort to supply them with hay of good quality.

4. With the exception of poultry, which need particularly liberal amounts of riboflavin, there is generally no lack of the other vitamins in the rations commonly fed to young stock.
