|dc.description.abstract||Combinations of molasses, urea (NPN), Phosphoric acid and two levels of Red Blood Cell (RBC) concentrate were studied to determine their stability, animal acceptability and animal response.
Lab. Test tubes and half gallon batches were made of the two liquid supplement mixtures to study their performance.
The supplements were chemically analyzed for protein and phosphorous. In vitro D. M. digestibility at 24, 48 and 72 hours was determined by running triplicates and using molasses as a control. The supplements were fed free choice, cafeteria style for 17 days, allowing 1 week for adaptation period.
The two mixtures showed considerable stability of up to eight weeks, when they started to show a loss of moisture; the protein content ranged from 31 to 34, the phosphorous level on both mixtures was .3%.
The in vitro dry matter digestibility data show that the digestibility level of both mixtures is high. Especially notable was the fact that the 20% RBC mixture was slightly higher than the 10% RBC.
As measured by voluntary intake, the acceptability of the 10% RBC mixture was greater than that of the 20% RBC mixture. This was significant at the .01 level. Average consumption was 3.34 lbs/head/day for the 10% while only 1.09 lb/head/day for the 20%. When feeding only the 20% RBC mixture the intake level was considerably higher than when both mixtures were offered.||en
