Table 1 Ingredients and chemical composition of the antepartum and postpartum diets on a dry matter (DM) basis

From: Oxidative status in dairy goats: periparturient variation and changes in subclinical hyperketonemia and hypocalcemia

Ingredient (% of DM) Antepartum Postpartum Nutrient composition Antepartum Postpartum
Alfalfa hay 15.36 18.42 DM (% of fresh) 45.10 48.20
Corn 20.72 23.16 Neutral detergent fiber (NDF, %) 42.20 37.70
Wheat bran 7.20 8.37 Acid detergent fiber (ADF, %) 18.50 17.40
Soybean meal 4.89 9.02 Crude protein (CP, %) 14.20 16.40
Wheat straw 7.57 0.00 Starch (%) 24.3 25.40
Corn Silage 35.35 30.66 Ether extract (%) 3.00 3.20
Corn germ meal 2.80 3.26 Calcium (Ca, %) 0.48 0.66
Cottonseed meal 4.40 5.12 Phosphorus (P, %) 0.36 0.37
Calcium hydrophosphate 0.44 0.51 Magnesium (Mg, %) 0.14 0.19
Limestone 0.40 0.46 Sulfur (S, %) 0.20 0.20
Sodium carbonate 0.32 0.38 Chloride (Cl, %) 0.47 0.25
Sodium chloride 0.40 0.45 DCAD (mEq/kg of DM) b -164 + 733
Mineral and vitamin premix a 0.15 0.19 NEL (Mcal/kg) c 1.53 1.62
  1. a The mineral-vitamin premix provided the following per kg of diets: vitamin A 250,000 IU, vitamin D 23,250 IU, vitamin E 1500 IU, manganese 800 mg, zinc 1800 mg, copper 370 mg, iron 2200 mg, cobalt 50 mg, iodine 30 mg, selenium 30 mg.
  2. b The dietary cation-anion difference (DCAD) was calculated using the formula DCAD (mEq/kg of DM) = (Na+ + K+) − (Cl + S2−).
  3. c Net energy for lactation (NEL) was estimated using CPM-Dairy software (version 3.0.8.1).
