Summary: Matthäus and Zubr (2000) have suggested that enzymatic hydrolysis of the glucosinolates in camelina seed may produce only nonvolatile isothiocyanates because of long carbon chains in its residue. In addition to this, camelina does not contain progoitrin, which can be converted into toxic goitrin. Therefore, the adverse effect of glucosinolates in CC may be less than that in rapeseed and rapeseed coproducts (Matthäus and Zubr, 2000). However, it should be noted that the NE values of experimental diets and ingredients were predicted from prediction equations using DE and ME values rather than direct determination of NE using indirect calorimetry for measurement of heat production (HP) by pigs. Dietary glucosinolates may affect HP by increasing production of thyroid hormones, which are involved in energy metabolism and HP within body, and metabolic activity in the liver and kidneys for detoxification of glucosinolates, which possibly affect the NE values of feed ingredients and diets and, therefore, additivity of NE values in mixed diets containing different level of dietary glucosinolates. Therefore, further study will be required to determine the effect of dietary glucosinolates originating from CC on HP of pigs for testing additivity of NE in mixed diets containing CC.
