| description | The main objectives of this study are to determine the growth performance
and carcass composition of growing lambs raised on sweet corn stover silage.
The sweet com stover can be considered to be a better quality animal feed as
indicated by its high crude protein content and its low neutral detergent fibre, acid
detergent fibre and acid detergent lignin as compared to other cereal crop straws.
The nutrient content of the sweet com stover could be maintained by ensiling. The
ensiling process takes four weeks and the silage can be stored for 16weeks without
any change to its nutritive value. When rice bran is added to the ensiling, the crude
protein and the potential degradability increase. However, addition of molasses
only increased potential degradability but decreased crude protein content.
The total intake of sweet com stover silage by growing lambs was 24.2 g dry
matter/kg body weight. The concentration of rumen ammonia was 229.2 mg Nil and
the total volatile fatty acids was 63.1 mM/i. With concentrate supplementation
(200 g/animal/day; 20 - 30% crude protein, fish or soybean meals as source of protein) on the sweet corn stover silage basal diet, the total dry matter intake
increased (29.0%), however, dry matter intake of sweet corn stover silage decreased
( 1 3 .6%). The concentrate supplementation also increased rumen ammonia (28. 1 %)
and total volatile fatty acids (5.5%).
Providing 100% of the sweet corn stover silage to the lambs was sufficient
for maintenance as well as for a little average daily gain (10.7 g/day) with a dressing
percentage of 42.5%, carcass fat of 3.3% and lean to bone ratio of 1.86:1.The
concentrate supplementation increased the average daily gain to 7l.6 g/day, the
dressing percentage to 47.7%, the carcass fat to 8.3% and the lean to bone ratio to
2.8: l .
Fish meal or soya bean meal as a source of protein supplementation had a
similar effect on the nutritive values, growth rate and carcass composition. |
