Description

Two experiments were conducted to determine the effect of pelleting conditions of rapeseed meal diet on 5-vinyl-2-oxazolidinethione (OZT) content and thyroid weight of chicks.<br>Male White Leghorn chicks were fed rapeseed meal diets containing 20% rapeseed meal or a soybean meal control diet. Rapeseed meal diets were offered as non-treated mash, non-steam pelleted and reground mash, steam pelleted (75°C) and reground mash or steam pelleted (90°C) and reground mash.<br>Thyroid weight of chicks fed rapeseed meal diets increased about two times as large as that fed the soybean meal control diet. Steam pelleting of the rapeseed meal diet decreased 4-6% of OZT content in the diet, but had no significant effect on thyroid weight of chicks. Non-steam pelleting of the rapeseed meal diet had no effect on both OZT content in the diet and thyroid weight of chicks.
