Abstract
The study as summarized herein was undertaken to throw some light on some of the factors affecting the salt consumption and requirements of fattening lambs.
That salt is essential to the health and thrift of sheep is the universal experience of practical sheep husbandmen and livestock authorities. There is almost unanimous agreement that, wherever practicable, salt should be allowed to sheep "free-choice" style.
This free-choice or ad libitum method of feeding salt to fattening lambs suggests a number of problems. How much salt will the fattening lamb consume daily when it is self-fed? Will the lamb's requirement for salt, as evidenced by the consumption, vary with the different rations? How much salt is required for 100 pounds of lamb gain on different rations? Does the requirement of lambs for salt vary as the fattening period progresses? How does the salt consumption of fattening lambs compare with that of steers?
1 A rather comprehensive bulletin entitled "The Salt Consumption of Sheep: Fattening Lambs," by John M. Evvard, L. C. Brown, C. C. Culbertson and W. E. Hammond will soon be published from the Iowa Agricultural Experiment Station.
