Table 3. Cell activities in bovine mammary epithelial cells across both timepoints of 48 and 60 h after lysine or methionine subtraction to ¼ the normal concentration¹.

Item	Treatment²			SEM	P-value³
Item	CTL	LK	LM	SEM	LK	LM
Protein synthesis rate	272	213	186	11.5	<0.01	<0.01
Fat synthesis rate	83.4	81.5	76.1	8.0	0.87	0.53
Cell proliferation rate	13.2	10.5	8.4	0.8	0.03	<0.01
PDI (arbitrary units)	0.66	0.70	0.50	0.03	0.93	0.72

¹Values are least squares means ± SE (n = 6) in dpm/ng DNA unless otherwise stated.

²CTL = control; LK = low lysine; LM = low methionine; PDI = endoplasmic reticulum tracker protein disulfide isomerase.

³Linear contrast of LK or LM vs. CTL.
