A field trial on the effects of algae addition to calf feed. Project T2014

Research output: Book/ReportReportProfessional

Abstract

This report describes a field trial that took place between 1 July and 2 October 2015 at a Dutch rose veal farm in which a group of 30 calves was fed with formula milk of which 2% of the dry matter was substituted with concentrated freshwater algae. The control group consisted of 25 calves. The farm owners collected the data, which were statistically analyzed and reported at ACRRES. During the trial the following parameters were monitored: calf weight, amounts of formula milk, water, solid feeds, feed additions and medication, deviations in manure structure, and disease incidence. Individual calf weights were determined at arrival and four weighing dates. The main conclusion of this field trial is that the addition of algae to the formula milk of rose veal calves during a period of 44 to 51 days did not have a statistically significant effect on calf weight increase up to 13 weeks after the start of the trial.
