Popis:	Two experiments were carried out to determine whether 5% of dried grass meal as a source of carotene, together with 1 i.u./g. of synthetic vitamin D3 (cholecalciferol), can satisfactorily replace cod-liver oil in providing vitamins. A and D3 in chick mashes, and to assess the stability of these vitamins in normal commercial storage for up to 16 weeks. The rate of loss of carotene varied for different mashes and averaged 1% per week; grass meal stored alone lost only 0.5% of its carotene per week. The vitamin-D supplement proved ample at the end of the storage period, and with dried grass of good quality satisfactorily supplied the needs of chicks.
