| Abstract | ||
| Twenty eight Frisian calves are divided into four groups, each group contain seven calves each, to study the effect of adding some nutritive antibiotic (Monensin, Salinomycin, and Lasalocid) to the salt block, on the frizian calves. The study lasted for (120) days and the results declared a decrease in the values of the Acetic acid to be compared with the controlling group, yet it is an immaterial decrease. As for the values of the Acetic acid of the other three groups, the results indicated immaterial dissimilarities of about (p<0.01) to be compared with the controlling group. The highest value has been recorded in the fourth group (33.04) and the immaterial dissimilarities disappeared among the experimental groups. The values of the butyric acid have demonstrated an absence in the immaterial dissimilarities among the three groups and the controlling group. An immaterial decrease of about (p<0.01) happened in the values of the NH3 in the three groups to be compared with the controlling group. This is a natural result since this will lead to the decrease of the lost energy in the potbelly of the animal so that the pure energy of the diet will be increased. All these activities will lead to a good growth as well as an improvement in the efficiency of using the forage. The test of the value of the PH has recorded an immaterial height of about (p<0.05) for the three groups to be compared with the controlling group. As for the total product of the volatily fatty acid of the fourth group, in comparison to the controlling group, has an immaterial decrease of about (p> 0.01). An immaterial difference is observed between the second and the third groups of about (p> 0.05) to be compared with the controlling group. Thus, we conclude that the nutritive antibiotic has an important role in the improvement of the Frisian calves' growth as well as an increase in the efficiency of its nutritive transformation. In addition to that, the three antibiotics share an equal efficiency in their effect | ||
