| Abstract | ||
| This study was carried out at the Sheep and Goat Research Station, State Board for Agricultural Research (20 km west of Baghdad), and over the production season 2009-2010, using 36 ewe Turkish Awassi sheep. The aim of the study is to investigate the effect of parity on lactation period (LP), daily milk yield (DMY), total milk production (TMP), production milk in difference stage on lactation (M1, M2 and M3) and percentage of major milk composition. The general linear model (GLM) within the SAS was used to analyzed the data. Significant effect of parity in LP, DMY, TMP, M1, M2 and M3, respectively, increased of all this traits in the third season of milk production. Significant effect of parity in fat percentage at M1, M2 and mean of lactation, except M3 which did not-significant with difference of parity. Lacked significant of protein percentage in milk with difference of parity of ewes in this study, except the protein percentage in second stage of lactation- (M2) (P<0.05). The effect of parity was significant in lactose percentage in M2, M3 and mean of lactation, lacked significant in M1 of lactation. Lacked significant of total solid percentage in milk with difference of parity of ewes in this study, except the total solid percentage in second stage of lactation (M2) (P<0.05). | ||
