Table 4. Response in serum biochemistry of DMRs to CM inclusion levels

Traits	CM inclusion levels					Significance levels
	T1	T2	T3	T4	SEM	Linear	Quadratic
Blood urea nitrogen (mmol/L)	8.02a	5.55b	4.40c	4.02c	0.40	NS	NS
Glucose-fasting (mmol/L)	3.66	3.85	3.72	3.74	0.16	NS	*
Total protein (g/L)	55.60	63.40	55.70	63.00	2.64	NS	NS
Albumin (g/L)	16.70	14.80	16.30	15.80	0.54	NS	NS
Total cholesterol (mmol/L)	1.20a	1.50b	1.38b	1.48a	0.06	NS	NS

Least square means in the same row with different superscript letters differ significantly (p<0.05); NS, not significant (p>0.05);
p<0.05.
DMRs, Dohne Merino rams; CM, canola meal.
