The Effect of Different Levels of Wild Reeds(Saccharum spontaneum) with Concentrated Fodder on some Physical and Biochemical Blood Parameters of Local Iraqi Lambs

Abstract

This experiment determined the best ratio of fortified and unsupported dried reed with urea in a concentrated feed mixture to maximize production and minimize cost. About 24 Iraqi lambs (17.27 ± 0.54) aged 3-4 months were used in this study, which lasted for 90 days in the farms of the Production Department of the College of Agriculture at the University of Tikrit from 9/19/2022 to 12/17/2022. Lambs were fed at 3% of body weight on diets of different content of wild reeds fortified and unfortified with urea mixed in the form of 8 mm pellets with concentrated fodder (black barley, wheat bran, yellow corn) and Which was divided into six treatments, the first three were without urea in the following ratios: 60 reed:40 concentrate, 40 reed : 60 concentrate and 50 reed:50 concentrate. As for the second three treatments, they contained the same proportions as the first three treatments with 3% urea from the weight of roughage feed. The results showed high statistically significant differences (P≤0.01) differences between the treatments with regard to the physical blood characteristics. The hematocrit was significantly superior in the sixth treatment at (P≤0.01) compared with the other treatments, as it was 43.57 ± 0.16% while the first treatment was the lowest among the treatments, as it was 37.95 ± 0.10 %. As for hemoglobin concentration, the third treatment was significantly higher at (P≤0.01), superior to all experimental treatments. There were significant differences in the total number of red blood cells at (P≤0.01) for the sixth treatment 14.50 ± 0.04 × 106 / ml, which was the highest compared to the rest of the treatments. There is a significant superiority at (p≤0.01) in the concentration of white blood cells in favor of the sixth treatment (8.67 ± 0.17 × 103 / ml) over the third treatment (6.65 ± 0.06 × 103 / ml) and the other treatments. As for blood biochemical characteristics, the sixth treatment was Significantly higher at (p≤0.01) in the concentration of total protein and albumin (5.90 ± 0.04 and 3.85 ± 0.02) g / dL, respectively. As for the concentration of serum globulin, the first, fourth and sixth treatments were significantly superior at (p≤0.01) over the rest. The concentration of triglycerides in the sixth treatment was 75.92 ± 0.18 mg/dL, significantly superior at (p≤0.01) over the first treatment (72.47 ± 0.19 mg/dL) which was the least significant and over the rest of the treatments, the blood glucose concentration in The sixth treatment was significantly superior at (P≤0.01) over all treatments of the experiment, and the second treatment was the lowest, and the concentration of blood urea at the sixth treatment was significantly affected at (P≤0.01) as it was 35.37 ± 0.16 mg / dL, followed by the third and fifth treatment The sixth treatment was highly significant at (P≤0.01) over the rest of the experimental treatments. As for the creatinine concentration, it was 1.67 ± 0.08 mg / dL, followed by the fifth treatment and the rest of the treatments. We conclude from the results of the experiment that providing a diet consisting of concentrated fodder and rough fodder from wild reeds at a ratio of 50/50 gives very good results in the physical and biochemical properties of lambs blood at a lower economic cost per kilogram produced, especially when urea is added to the fodder provided to lambs.
