Extended Abstract
Introduction and Objective: The natural growth and development of the rumen tissue structure and absorption from rumen-reticulum depends on its morphological structure and the change in morphology causes the dysfunction of these tissues. The aim of the present experiment was to investigate the effect of using complete branches of Albizia on histomorphometry and histopathology of the rumen, liver, and kidneys.
Material and Methods: Twenty-four Arabi male lambs with 8 ± 1.3 months old and initial body weight of 28.8±5.34 kg were used in a completely randomized design with three treatments and eight replicates. The lambs were randomly assigned to one of three treatments: 1-control (No Albizia) 2- control + 50 percent complete branches of Albizia replaced with alfalfa 3- control + 75 percent complete branches of Albizia replaced with alfalfa. At the end of the experiment, three lambs from each treatment that was closer to the average weight were selected and slaughtered. Sampling was performed from gastrointestinal, liver, and kidney tissues.
Results: Reticulum wall thickness in treatments containing 50 and 75 percent of All the branches of Albizia was greater than the control treatment And was significant in the 50 percent treatment compared to the control treatment (p<0.05). The thickness of the muscular layer of the reticulum in the recipient 50 percent treatment was higher than the control and 75 percent treatment and was significant compared to the 75 percent (p<0.05). No significant difference was observed between other indicators of the reticulum. The thickness of Rumen tunica muscularis and Rumen wall thickness in 50 and 75 percent treatments were higher than the control treatment (p<0.05). No significant difference was observed between other indicators of the rumen. The treatments didn't affect the villus height of rumen and reticulum, however, the height of ruminal villi in control treatment was numerically higher than 50 and 75 percent of treatments. Liver and kidneys were in better condition in control treatment than other treatments.
Conclusion: In general, according to the results of the present experiment, no significant negative effect was observed on the histomorphometry and histopathology of rumen, liver, and kidneys; even positive results such as reducing the penetration of inflammatory cells were observed during the use of the Albizia plant. Therefore, its use in animal nutrition can be recommended after some performance studies.
