GROWTH CURVE AND RATES OF ABSOLUTE AND RELATIVE GROWTH OF LOCAL KID GOATS IN NORTHERN MÉXICO
Background. A growth curve allows us to identify the potential of animals to gain live weight. The growth curve of local goat kids in northern Mexico is unknown. Objective. Characterize the growth curve of local kids using two non-linear models and estimate the absolute and relative growth rates. Me...

| description | Background. A growth curve allows us to identify the potential of animals to gain live weight. The growth curve of local goat kids in northern Mexico is unknown. Objective. Characterize the growth curve of local kids using two non-linear models and estimate the absolute and relative growth rates. Methodology. The Gompertz and Logistic models were used to characterize the growth curve and absolute and relative growth rates of the kids. The models were compared using four goodness-of-fit criteria. Results. The growth curve was similar with both models, the kids had mature weights of 62.5 and 58.3 kg with Gompertz and Logistic, respectively, although their maturation rate was slow. The Gompertz model slightly outperformed the Logistic in the goodness of fit. Both models were similar in estimating absolute and relative growth rates. Implications. The high mature weights obtained by the kids suggest a potential to start a dual-purpose production system in the region, which will result in higher income for producers. Conclusion. Local goat kids from northern Mexico mature slowly but reach a high mature weight. |
