PROXIMATE PRINCIPLES AND B-VITAMINS IN SASKATCHEWAN FEED GRAINS

Feed Grains and Forage

rarily checked in 1932 because of the short corn crop in the western Corn Belt in 1931. Indications are that the increase in hog production is now being resumed. Low prices for cows have resulted in the holding back of dairy and beef cows, and breeding stock on farms is now at the highest level in the history of this country. Sheep numbers, which reached a new high record in 1931, were reduced ...

Priority Area Review : Feed Grains & Feed Efficiency

Liposoluble vitamins in Crustacean feed: Metabolic and Histological responses.

Vitamins are vital for normal growth and survival of living organisms and they are distributed in feedstuffs in small quantities. This review is focused on the liposoluble vitamins (A, D, E and K) in the diets and metabolic responses of the Argentine penaeoid shrimps Pleoticus muelleri and Artemesia longinaris, distributed along the South American coast line. Growth, survival and histological a...

Can We Feed More Distillers Grains?

Distillers grains is a very good protein source (>30% crude protein) which is high in ruminally undegradable protein and is very good energy source (NEL ~1.02 Mcal/lb of dry matter; [DM]) for lactating cows and growing cattle. The modest fat concentration (10 to 12% of DM) and the readily digestible fiber (39% neutral detergent fiber; NDF) contribute to the high energy in distillers grains. The...

Metabolism and Nutrition IV: Vitamins and Minerals and Feed Manufacturing

Research on which NRC trace mineral requirements are based was done with inorganic transitional minerals and purified and semi-purified diets. Research with organic trace minerals and standard rations have demonstrated that requirements are much lower than the levels set by NRC, due to the greater availability of these organic minerals. Further, not all organic minerals are the same. Pullets fr...
