Several factors including age, genotype, and sex affect the rate of body protein and fat deposition and, thus, the nutritional requirements for growth. Thus, the objective of this meta-analysis was to develop equations for estimating net protein (NP_g) and net energy (NE_g) requirements for growth of different sexes in dairy goats. A database of 244 individual records of Saanen goats weighing between 4.61 and 51.0 kg of body weight, from 7 comparative slaughter studies was used. Allometric equations were developed for body protein and energy contents in the empty body weight (EBW) as dependent variables and EBW as the allometric predictor. Parameter estimates were obtained using a linearized (log-transformation) expression of the allometric equations using the MIXED procedure of SAS 9.4. The model used included the random effect of study, and the fixed effects of sex (intact male, castrated male, and female; n = 93, 79, and 72, respectively). Net requirements for growth were estimated as the first derivative of the allometric equations. The NP_g equations differed across sexes (P = 0.083). The allometric equation for intact and castrated males was log₁₀ EBW protein (g) = 2.221 ± 0.0224 + 1.015 ± 0.0165 x log₁₀ EBW (kg); and for females: log₁₀ EBW protein (g) = 2.277 ± 0.0288 + 0.958 ± 0.0218 × log₁₀ EBW (kg) (σ_e = 0.0374; σ_s = 0.0196). The NP_g requirements for males were nearly 10% greater than those of females. The NE_g equations also differed between sexes (P < 0.001). The allometric equation for intact males was: log₁₀ EBW energy (kcal) = 2.988 ± 0.0323 + 1.240 ± 0.0238 x log₁₀ EBW (kg); for castrated males: log₁₀ EBW energy (kcal) = 2.873 ± 0.0377 + 1.359 ± 0.0283 x log₁₀ EBW (kg); and for females: log₁₀ EBW energy (kcal) = 2.820 ± 0.0377 + 1.442 ± 0.0281 x log₁₀ EBW (kg) (σ_e = 0.0472; σ_s = 0.0309). The NE_g requirements of castrated males were nearly 14% greater than those of intact males, and nearly 15% less than those of females. These results indicate that NP_g and NE_g requirements differ among sexes in growing dairy goats. This distinction is not done in the prevalent nutritional requirement systems (FAPESP grant # 2014/14734–9).
