The La Sota strain proved to be a better HI antibody producing strain than the F and CDF-66 strain of NDV. But challenge experiments showed that there was no significant differences between the protection ability of F, CDF-66 and La Sota strains of NDV and the route of administration.en-USCDF-66Newcastle Disease VirusVaccinesChicksArticle
