Table 3 Effects of phytochemicals feed-additives on productive performance, carcass and meat quality of bovine and ovine

From: Dietary inclusion effects of phytochemicals as growth promoters in animal production

Reference Phasea Phytochemicals Dosage Productive performance b Carcass quality Meat qualityc
[20] Bovine F Ferulic acid
  ↑ Feedlot performance FA ↑ carcass characteristics and wholesale cut yield FA (30 days)
↑ Tender, juicier and flavored meat
smaller increases in TBAs values
[33] Bovine F Cinnamaldehyde
- ↑ FI (initial month)
Minimal effects on ADG and FE
Minimal effects on carcass traits similar to positive control -
[52] Bovine F Alfalfa extract, anise, capsicum
Mixture of Cinnamaldehyde and eugenol (CIE)
- CIE and alfalfa ↓DMI and water intake - -
[55] Bovine F Thyme and cinnamon essential oils 5 g/d/calf NE - -
[79] Ovine F Ferulic acid 300 mg of FA/animal -BWG and ADG tended to ↓ d 17 to 34 NE -
[109] Ovine F Hesperidin 1500 and 3000 mg/kg NE NE ↓ Lipid oxidation values
[115] Bovine G Stryphnodendron adstringens,
Commercial product 1 (essential oils) and commercial product 2 (cashew nut)

Ovine G Carvacrol 0.30 and 0.35 g/Kg of Dry matter NE NE -
[116] Bovine G CIN and Thymol blend 100 or 200 mg/Kg of diet Minimal effect on growth rate and FE - -
[122] Ovine F Cinnamaldehyde 100, 200 and 400 mg/kg of Diet NE NE ↑ off-flavour intensity
[130] Bovine F Kocetin™-Quercetin 21 and 42 ppm
