Overview:
By using strain three-way cross hybrid SPF pigs, the
lysine demand was estimated from the relationships
between the lysine level in feed and the gain of the
body weight and between the feed demand rate and the
density of urea nitrogen in the plasma, and the
following results were obtained.
1. The lysine demands as the lysine content
in feed were 0.78 %, 0.82 %, 0.64 %, and 0.67 %
in early fattening hogs, early fattening sows,
late fattening hogs, and late fattening sows,
respectively.
2. The digestible lysine demands per day were 17.4 g,
16.3 g, 16.7 g, and 15.2 g in early fattening hogs,
early fattening sows, late fattening hogs, and late
fattening sows, respectively.
3. The digestible lysine demands per gain weight of
1 kg were 17.9 g, 18.4 g, 17.7 g, and 16.9 g in
early fattening hogs, early fattening sows, late
fattening hogs, and late fattening sows,
respectively.
