Role of Poultry Star and Alcoholic Myristica fragrans extract on calf rotavirus diarrhea

Abstract

This study was carried out to investigate the effect of using alcoholic Myristica fragrans extract and Poultry Star Probiotic on rotavirus infection in newly born calves. The results showed that the extract of Myristica fragrans inhibited the virus at (90-100%) during the average of continuous diarrhea (2.4) days, which showed that the detection of virus at beginning of diarrhea and the recovery by using Latex Agglutination (LA) was (73.3%), but in Haemagglutination (HA) and ELISA tests the detection of virus at beginning was (128-256), (73.3%) and in recovery was (64-128), (66.6%) respectively. In Probiotic group the inhibition of virus was (50-76.6%) during (4) days. The percentage of positive causes by using LA & ELISA tests showed the first samples were (80%), (86.6%) and at healing the results were (40%), (66.6%) respectively, but by the method of detection of virus by HA test showed the virus titration at beginning was (32-64) which was less than the recovery (256-512). In control group the inhibition of virus was (36.5-40%) during (5.5) days, which showed that the detection of virus by using LA and ELISA tests in percentage of (66.6%) & (73.3%) at beginning of diarrhea and (26.6%) and (26.6%) respectively in healing, but by using HA test the virus titration of samples at beginning of diarrhea was (32-64) which was less than recovery samples (1024-2048). The data presented in this study contribute; that the Myristica fragrans given with colostrums to calves from one day of age for 14 days inhibit the virus during (2.4) days.
