Determination of hematobiochemical and fore stomach fluid constituents of llama (Lama glama) living in Egypt

Abstract

AbstractThere are no available data regarding the hematology, serum biochemistry, and fore stomach fluid constituents of llama (Lama glama) in Egypt. This study aimed to establish normal reference values for blood and fore stomach fluid constituents of llama and determine the influence of sex and season on these parameters under Egyptian conditions. The study was performed on (n = 38; 22 female, 16 male; 1–7 years) apparently healthy llamas located in the Giza Zoo and private zoo in the Ismailia Governorate. Samples were collected in two seasons and divided into summer and winter samples. Differences in the mean and range values of packed cell volume, serum minerals, fore stomach fluid pH, and total protozoal count in Egypt were recorded. Sex and season had minimal effects on hematology and only erythrocyte count showed a significant (p < 0.05) increase in males compared with females. Regarding serum biochemistry, males showed significant (p < 0.05) increases in alanine transaminase and calcium levels, while globulin significantly (p < 0.05) increased in females. The influence of season on serum biochemistry was evident in alanine transaminase, total protein, albumin, and chloride which increased significantly (p < 0.05) in summer, while urea, bilirubin, and magnesium increased significantly (p < 0.05) in winter. Fore stomach fluid pH and ammonia showed significant (p < 0.05) increases in winter, while the total protozoal count increased significantly (p < 0.05) in summer and in males compared with females. The results obtained in this study can serve as reference values for the hematobiochemical and fore stomach fluid constituents of llama in Egypt.
