Abstract<\/strong><\/p>\n\n\n\n

The\nresearch was carried out at Hama Research Center, General Commission for\nScientific Agricultural Research (GCSAR) within 2013 and 2017, with the aim of\ndefining milk production curve for goats and studying some of the factors\naffecting it. The analysis of variance was used to determine the effect of different\nfactors, and Duncan test for comparison of averages, using SAS program (1996),\nand the incomplete linear gamma function was used to estimate the parameters of\nequation (a, b, c). The parameters of the milk production curve in Shami goats were\nabout: 1.44 \u00b1 0.07 kg for function a (average initial production), 0.41 \u00b1 0.01\nkg for b (increase to peak), and 0.12 \u00b1 0.01 kg for c (drop after climax). The\npeak milk production (PY) and peak week TPY, Persistency, R2<\/sup>,\nAverage Mean Square Error (MSE), Square Deviation (PSB) 1.58 Kg, 3.42, 85%,\n0.98, 0.14 and 0.15 respectively. The genetic equivalent of coefficients a, b,\nc, py and Persistency were 0.18, 0.12, 0.1, 0.11 and 0.12 respectively. The\ncoefficients for a, b, c, py and Persistency were 0.3, 0.23, 0.24, 0.12 and\n0.22, respectively. Thus, it can be concluded that the incomplete gamma\nfunction was sufficient to describe the milk curve of the Shami goat.<\/p>\n\n\n\n
