afs-71751	Kossila, Vappu; Niemelä, Paavo; Koskenkorva, Erkki	Variations in serum calcium, inorganic phosphorus and magnesium levels due to stage of lactation, season, and age in Ayrshire cows injected with vitamin D3 prior to calving	1970	13	.pdf	application/pdf	6972	468	67	According to Muir et al. (1968), vitamin D fed cows recovered faster from hypocalcemia induced by Edta infusion than normal cows or cows with history of milk fever. Even though the serum magnesium level as a whole tended to be lower in lactating than in dry cows, the highest mean value (2.01 mg%) was noted during the days 16—30postp., this value being significantly (P < 0.002**) higher than those obtained during other phases after calving (Table 1).	cache/afs-71751.pdf	txt/afs-71751.txt
