Abstract

The study was conducted at the Faculty of Agriculture of the University of Tikrit from 12/9/2021 to 12/12/2021 of 91 days to study the effect of adding glycerol as an alternative source of energy and feed in some productive qualities represented in growth (weight gain), some blood and biochemical parameters and the concentration of some hormones using 12 The lambs were divided into three nutritional groups with four lambs each group, the first group without glycerol, the second 30 ml glycerol and the third 60 ml glycerol. The results showed a moral increase (P?0.05) between the factors in the rate of daily weight gain of the two lambs, as it outperformed the third treatment (60 ml glycerol/carries/day) compared to the first treatment (control) that was free of additions and the second treatment contains (30 ml glycerol/pregnancy/day). This results were reflected in the total weight gain of the two loads, as the third treatment (60 ml glyserol/day/pregnancy) exceeded morally (P?0.05) by an average of (16.35) kg compared to the first treatment (control) (9.85) kg and the second (30 ml glycerol/day/carries) (10.92) kg. The results also showed that the third treatment (60 ml/day/carries) was morally superior (P?0.05) in dietary conversion efficiency at a rate of (5.53 fodder/kg meat) compared to the second and third factors (7.68 and 9.64 fodder/kg meat), respectively. Differences between factors in the rate of daily feed consumption were also seen. With regard to the results of biochemical blood characteristics (glucose, cholesterol, total protein, urea) at the end of the experiment, there was a moral increase in glucose, as the third treatment recorded a moral increase (P?0.05) in its concentration compared to the second and first treatment, while thyroxin T4 recorded a moral increase (P?0.05).
