Description
This article concerns a report that was part of an extensive project conducted at the
Livestock Unit of the Dickinson Experiment Station, at Dickinson
m western North Dakota. The objective of the project reported in this report was: to study the effects of a vitamin A (carotene) deficiency on (a) the breeding performance and (b) the health and thrift of a herd of beef breeding cows. This project was started as a result of reports from various individuals which indicated considerable losses of calves, lambs and pigs at birth or soon after birth and difficult parturition and poor milk production of breeding females.
