Abstract

The study was conducted between 2015 and 2017 on 26 species of Ceratonia siliqua L. at four locations viz. AL Dakaka, Wadi Qandil, Um Al-Toyoor and Al-Baseet, in the north-western region of Latakia governorate, Syria in order to study some chemical properties in the pods and seeds of these species. For total sugars (%), the highest percentage was found in T8 pods (57.7%) followed by the D3 (56.9%). The percentage of protein in the pods ranged between (5- 8.2%) and seeds (25-33%) where T8 recorded the highest values. The highest fat value was found in T8 (1.83%) and D3 (3.75%). The percentage of dry matter in the pods ranged from 12.15% in K3 and 8.16% in T1. These genotypes differed genetically more than because of environmental conditions because the locations of the study were geographically close. The genotypes were distributed within the relationship tree in three groups, the first included 3 genotypes and the third contains 9 genotypes from all the study locations. In contrast, the second group included 4 genotypes from the locations of Um Al-Toyoor, Wadi Qandil and Al-Dakaka.

Key words: Carob (Ceratonia siliqua L.), Chemical composition, Sugars, Protein, Fat, Dry matter, genotypes.

Abstract

This study was carried out at sheep section – Shami Camels Research Station, Damascus country side. Twenty-four lactating Awassi ewes homogenous in terms of age (5 years) and production season (fourth) and milk yield in the previous season. The ewes were divided randomly into three groups. All housing and management conditions were similar for all sheep throughout experiment period (105 day post-weaning). The first group T (control) was fed on basic ration (concentrate feed, barley-vetch hay, fresh forage), while the second T1 and the third T2 groups were fed on basic ration supplemented by yeast (3 and 5 g/head/day, respectively). The results showed that the average total gain was higher in T2 (P≤0.05) as compared with control (6.25 vs. 4.89). Milk yield amounted 65.82±2.47, 71.57±3.86, and 70.27±7.81 kg for T, T1 and T2, respectively. T1 milk yield was higher (P≤0.05) by 8.7% than that of T. There was no significant differences between the three groups for milk components (fat, protein, lactose and total solids), while amount of total fat was significantly (P≤0.05) more than 16.1 and 13.7%, respectively for T1 and T2. It can be concluded that the addition of live yeast Saccharomyces cerevisiae at a rate of 3 g/head/day to the diets of dairy ewes gives the highest milk production vs 5 g/head/day for better gain in body weight.

Keywords: Awassi sheep, Yeast culture, Milk yield, Fat.
