Quantitative determination of the amino acid content of rumen fluid from twin steers fed soybean oil meal or urea

Crude protein, or protein as the term is commonly used, represents all nitrogen-containing compounds in the feed. True protein is that portion of the protein which has been formed by the combining of amino acids. The value of any protein supplement is determined by its amino acid content plus the ability of the animal to synthesize true protein in the digestive tract from non-protein nitrogen sources. The purpose of this test was to determine the amino acid content of rumen fluid of steers fed soybean oil meal or urea

The effect of added calcium and phosphorus with and without added protein to the ration of steers on bluestem pasture

This experiment was designed to evaluate the desirability of supplementing bluestem pasture as indicated in the title. Forty Hereford steer calves were divided into four lots of 10 each and fed the following experimental rations per head daily: Lot 1. Two pounds of dehydrated molasses (a molasses product dried on soybean hulls) Lot 2. Two pounds of dehydrated molasses and 39.1 grams of dicalcium phosphate. Lot 3. One pound of dehydrated molasses and 1 pound of 41% corn gluten meal. Lot 4. One pound of dehydrated molasses and 1 pound of 41% corn gluten meal plus 29.6 grams of dicalcium phosphate

The value of enzymes added to cattle rations

Three lots of 10 animals were fed the same ration except for the added enzymes. The average daily ration is shown in Table 25, as are results of the test for the first 112 days. There are no significant differences in gains at present; however, lot 12, which receives a combination of enzymes that act upon carbohydrates and protein, has a slightly higher rate of gain. Animals in lot 12 also have a tendency to clean up their feed better than those in either other lot. This test will be continued until the animals are ready for slaughter

Rolled vs. finely ground pelleted sorghum rain in cattle rations

This is a progress report of another test to further evaluate methods of sorghum grain preparation. Twenty of the heaviest steer calves purchased for experimental work were divided into two lots of 10 animals each. The daily ration is shown in Table 27. The only difference in the ration is that lot 3 received rolled sorghum grain and lot 4 finely ground pelleted sorghum grain. The gains and feed efficiency up to this time are essentially the same. The feed cost per 100 pounds gain is exactly the same. After completing the wintering phase, these animals will receive a fattening ration

The value of grain sorghum harvested as silage and as dehydrated pellets

Combine-type sorghum grain is widely grown in Kansas, and normally only the grain is harvested. In many instances, moisture conditions at harvest time are such that the grain cannot be stored without artificial drying. Sometimes there is danger of losing immature grain because of early frost. This test was planned to study the value of the entire grain sorghum plant harvested as silage and as dehydrated pellets

Rolled vs. finely ground pelleted sorghum grain in cattle rations

Twenty Hereford steer calves were divided as equally as possible on the basis of weight and conformation into two lots of 10 animals each. The average daily rations are shown in Table 22 for the wintering and fattening phases. The ingredients were the same in both lots except rolled grain was used in lot 1 and finely ground pelleted grain in lot 2. The concentrate part of the ration was kept constant, with all the roughage the animals would clean up

Cobalt bullets for beef cattle

Cobalt is a trace mineral element which is essential to the health and well-being of animals. If it is deficient in the ration, it should be supplied. A cobalt bullet, which is placed in the rumen, was developed in Australia for sheep and cattle on cobalt-deficient pastures or rations. These cobalt bullets were found to be effective in preventing cobalt deficiency. Cobalt bullets are now available in this country. The bullet is composed of 90% cobalt oxide and 10% binding agent. The weight is 20 grams for cattle and 5 grams for sheep. The bullet is placed in the rumen with a balling gun. Since it is heavy, it remains in the rumen and allows cobalt to become available to the animal. Bullets were recovered at slaughter in some of these tests after over 300 days
