Table 4 Recalculation of the average body weight of several animal types
Animal type | Linear growth | Transition | Fully grown | Birth weight (kg) | Weaning weight (kg) | Age at the end of the linear gain phase (d) | Weight at the end of the linear gain phase (kg) | Age at the fully grown stage (d) | Weight at the fully grown stage (kg) | Average body weight (kg)a | Authors correction and other comments that explain dissenting suggestions for default values in Table 3 (body weight, kg) | References |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
Calf (0–6 months) | x | – | – | 50 | 50 | 365 | 300 | – | – | > 175 | Production ends earlier, but 140 seems to be a little low | [115] |
Dairy cow | – | x | x | 50 | 50 | 365–450 | 300–350 | 750–1250 | 500–800 | > 550 | 425 seems to be low | |
Cattle (> 0.5 y) | – | x | x | 50 | 50 | 180–300 | 250–380 | – | – | > 415 | New category; production ends earlier (330) | [117] |
Weaner pig (up to 25 kg) | x | – | – | 1.4 | 6.5–8.0 | 13–15 | 7–13 | – | – | 13.2 (15.8) | Birth weight was neglected; therefore, 12.5 seems to be low | |
Fattening pig (25–125 kg) | x | – | – | 1.4 | 6.5–8.0 | 70–160 | 25–125 | – | – | 75 | Production ends earlier; therefore, 65 is realistic | |
Sow (with litter) | – | x | x | 1.4 | 6.5–8.0 | 180–200 | 1–130 | 600–1000 | 320–380 | > 280 (> 310) | 240 seems to be low | |
Boar (25–125 kg) | x | – | – | 1.4 | 6.5–8.0 | 200–220 | 1–170 | 500–800 | 380–420 | 75 | Production ends earlier; therefore, 65 is realistic | |
Broiler | x | x | – | 0.04–0.05 | – | 28 | 1–1.2 | 63–84 | 3.1–4.1 | 1.6 | Production ends earlier; therefore, 1.0 is realistic | |
Laying hen | – | x | x | 0.04–0.05 | – | 120–140 | 1.1–1.2 | 210–560 | 1.6–2.5 | > 1.5 | Corrected for underestimation; 1.6 is realistic | |
Replacement layer | x | – | – | 0.04–0.05 | – | 120–140 | 1.1–1.2 | 210–560 | 1.6–1.8 | > 0.6 | Corrected for underestimation; 0.8 is realistic | |
Broiler breeder | x | x | x | 0.04–0.05 | – | 189–200 | 2.5–2.75 | 280–420 | 3.5–3.75 | > 1.4 | Corrected for underestimation; 1.7 is realistic | |
Turkey | x | x | x | 0.06 | – | 48–50 | 2.2 | 91–126 | 6–9.5 | > 4.8 | Corrected for underestimation; 6.5 is realistic | [127] |
Duck | x | x | – | 0.04–0.08 | – | 14–49 | 0.5 | 70–140 | 3.1–3.8 | 1.9 | Production ends earlier; therefore, 1.6 is realistic | [128] |
Horse | x | x | x | 48 | 180–200 | 250–330 | 200–250 | 480–720 | 400–700 | > 375 | Corrected for underestimation; 400 is realistic | |
Dairy goat | x | x | x | 4.7 | 8–14 | 85–90 | 10 | 270–390 | 30–60 | > 33 | New category | |
Dairy sheep | x | x | x | 4.4 | 20–25 | 60 | 23.7 | 230–370 | 50–60 | > 33 | New category | [134] |
Rabbit | x | x | – | < 0.5 | 0.6–0.7 | 30 | 0.8 | 100–300 | 3.5–4 | 2.3 | Production ends earlier; therefore, 1.4 is realistic |
