Effect of Anthelmintic and recombinant bovine Somatotropin on biochemical changes in blood of gastrointestinal nematode infected ewes during estrus cycle.
Abstract: The aim of this study was designed to determine whether treatment with ivermectin and/or recombinant bovine Somatotropin hormone (rbST) can improved the health condition of subclinically gastrointestinal nematode-infected ewes during the oestrus cycle. Twenty cyclic native ewes were chosen (aged between 2-4 years old). They were divided into four groups, the first group was treated with ivermectin, the second group was treated with rbST hormone, the third group was treated with both of ivermectin and rbST hormone and the fourth group remained infected with gastrointestinal nematodes as a control positive group. Feacal and blood samples were taken before the trial and during the different phases of oestrus cycle. Faecal egg count disappeared from the ivermectin and ivermectin/rbST treated ewes, and reached its lower levels at the end of the trial from the rbST-treated group indicating the increased resistance or resilience of the treated ewes while it was in its higher levels in the positive control group till the end of the trial. The control positive ewes exhibited anaemia, hypoproeinaemia, hypercholesterolemia, increasing in triglycerides levels, decreased HDL levels, increased Transaminases activities and lower levels in progesterone. Treatments with ivermectin and /or rbST were found to be effective in the resilience of the infected ewes indicating by improvement in all studied biochemical blood parameters as well as the progesterone status of the treated ewes. We conclude that resistance and resilience of GIN-infected ewes may be improved by ivermectin and/or rbST hormone treatment.
