¹Each 3 kg vitamins and mineral mixture contains vitamin A 12,000,000 IU, vitamin D₃ 2,200,000 IU, vitamin E 10,000 mg, vitamin K₃ 2000 mg, vitamin B₁ 1000 mg, vitamin B₂ 5000 mg, vitamin B₆ 1500 mg, vitamin B₁₂ 10 mg, pantothenic acid 10 mg, niacin 30,000 mg, folic acid 1000 mg, biotin 50 mg, choline 300,000 mg, manganese 60,000 mg, zinc 50,000 mg, copper 10,000 mg, iron 30,000 mg, iodine 100 mg, selenium 100 mg, cobalt 100 mg, CaCo3 to 3000 g
CFM₁: concentrate feed mixture contained 45% yellow corn
CFM₂: concentrate feed mixture replaced 25% of yellow corn with mango seed kernels
CFM₃: concentrate feed mixture replaced 50% of yellow corn with mango seed kernels
Gross energy (kcal/kg DM) was calculated according to Blaxter (1968). Each g CP = 5.65 kcal, g EE = 9.40 kcal, and g (CF and NFE) = 4.15 kcal
DE (Kcal/kg DM): calculated according to NRC (1977). Using the following equation: DE = GE × 0.76
Neutral detergent fiber (NDF) was calculated according to (Cheeke 1987). Using the following equation:
NDF = 28.924 + 0.657 (CF %)
NFC: non-fibrous carbohydrates, calculated according to Calsamiglia et al. (1995) using the following equation:
NFC = 100 – {CP + EE + Ash + NDF}
