Abstract

The growth curve in poultry is important to evaluate the performance and farming management system. This study was aimed to estimate the growth curve of body weight in goose. The growth curve in this study was estimated with non-linear Gompertz model through CurveExpert 1.4. software. Three goose breeds in Slovakia i.e. Landes (L), Pomeranian (P) and Steinbacher (S) were used in this study. Total of 28 geese (10 L, 8 P and 10 S) were used to estimate the growth curve. Research showed that the asymptotic weight (A) in those geese were reached at 5332.51 g (L), 6186.14 g (P) and 5048.27 g (S). Thus, the maturing rate (k) in each breed were similar (0.05 g/day). The weight of inflection was reached at 1960.48 g (L), 2274.32 g (P) and 1855.98 g (S) respectively. The time of inflection (ti) was reached at 25.6 days (L), 26.2 days (P) and 27.80 days (S) respectively. The maximum growth rate (MGR) was reached at 98.02 g/day (L), 113.72 g/day (P) and 92.80 g/day (S). According to the CurveExpert 1.4. software, the coefficient of determination (R2) with Gompertz model was 0.99 for each breed. It can be concluded that Pomeranian geese had highest of growth rate than the other breeds.

斯洛伐克混性鹅种Gompertz模型体重的生长曲线

家禽生长曲线是评价家禽生产性能和饲养管理制度的重要依据。本研究旨在估计鹅体质量的生长曲线。本研究的生长曲线采用非线性Gompertz模型，通过CurveExpert 1.4进行估计。软件本研究选用斯洛伐克的三个鹅品种，即朗德鹅(L)、波美拉尼亚鹅(P)和施泰因巴赫鹅(S)。选用28只鹅(10只L、8只P、10只S)进行生长曲线估计。研究表明，各品种鹅的渐近体重(A)分别为5332.51 g (L)、6186.14 g (P)和5048.27 g (S)，各品种的成熟率(k)相近(0.05 g/d)。挠曲重量分别为1960.48 g (L)、2274.32 g (P)和1855.98 g (S)。时间分别为25.6 d (L)、26.2 d (P)和27.80 d (S)。最大生长速率(MGR)达到98.02 g/d (L)， 113.72 g/d (P)和92.80 g/d (S)。用Gompertz模型对各品种的决定系数R2均为0.99。由此可见，波美拉尼亚鹅的生长率高于其他品种。
