| Abstract | ||
| This experiment aimed to investigate the effect of wool shearing and the environmental factors represented by some hot months of the year (July August and September) on some production characteristics in Turkish Awassi ewes .The experiment was carried out at the AL-Dawar Research Station in Anbar Governorate of the Agricultural Research Department / Ministry of Agriculture, from July 1, 2019 to September 1, 2019. 18 Turkish Awassi ewes, aged 3-5 years, with an average weight of about 55±1.43 kg, were used. The ewes divided into three treatments. The first group control (T1) were not shorned the wool, the second group (T2) wool of ewes were sheared at a distance of 1 cm from skin , while third group (T3) wool of ewes were sheared at level of the skin..The value of the weekly Temperature-humidity index THI in this study (32.33, 31.08, 31.70, 32.53, 33.45, 33.83, 34.60, 33.91, 31.90, 31.10, 31.84, 32.74) for the study weeks in a row, while the monthly THI was (31.63, 33.48, 31.82) for the months of the study in July August and September in a row. The results of the current study with respect to the weekly weight increase showed that there were significant differences between the treatments recorded in the tenth week of the experiment in which the rate of THI (31.10) reached a degree as the T2 group outperformed by a rate of (2.16 ± 0.802) kg compared to T1, T3 at a rate of (- 0.916 ± 0.723) (0.583 ± 0.490) kg, respectively. As for the overall weight increase rate, no significant differences were recorded between the factors despite the presence of an accounting difference recorded in favor of the group T2 compared to T3 and T1. No significant differences were observed in the birth weight between the treatments, although an accounting difference was recorded in favor of the group T3 compared to T2 and T1. No significant differences were observed in the feed consumption rate. The T1 group scored significantly higher in water consumption rate compared to T2 and T3. We conclude from the current study that the level of shearing wool in Turkish Awassi ewes in conjunction with high temperature has an effect in production characteristics by reducing the effect of heat stress on the ewes. | ||
