Hematological, biochemical, and antioxidant status in sheep with skin disorders suffering from zinc, copper, and vitamin A deficiencies.
Article in Open veterinary journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: A number of elements are essential for the body, including zinc (Zn), copper (Cu), vitamin A, and vitamin E. Nutritional deficiency diseases (ND diseases) are ailments that reduce the amount of animals produced, restrict commerce, and can result in severe economic losses. Mineral deficiencies, whether primary or secondary, create significant obstacles in livestock production because they are associated with decreased productivity, reproductive issues, and various health complications. Aim: This study aimed to determine the levels of Zn, Cu, and vitamin A, as well as the clinical signs, hematological, biochemical, and antioxidant changes that may occur due to the nutritional deficiencies of such trace elements and vitamin A in sheep. Methods: Several blood parameters were measured in normal or nutritionally deficient sheep. Such parameters included hematological levels, glucose, total protein, albumin, globulin, and oxidative stress GSH-Px, SOD, and CAT. This study was conducted on 100 sheep (male and female). Eighty sheep suffered from Zn, Cu, and vitamin A deficiency, and 20 were clinically healthy and served as the control group. Results: The diseased animals had the following clinical signs: depression, pica, pale mucous membrane, loss of hair around the eye, ear, and nose, erected wool, easily detached wool, depigmentation of the coat with apparent alopecia, decreased body weight gain with normal or decreased appetite. Some sheep were suffering from gait stiffness and parakeratosis with a marked increase in heart and respiratory rates, with normal body temperature. The obtained results showed significant decreases ( Conclusion: These results indicate that nutritional deficiencies of the trace elements Zn, Cu, and vitamin A make sheep liable to several skin disorders. Therefore, dietary supplementation of such macro and micro-elements is highly recommended to avoid such adverse effects.
