A cross-sectional study was conducted to reveal the hematology, serum biochemistry, and reproductive behavior of free-roaming cats in the Sylhet Division of Bangladesh.
Overall, 130 free-roaming cats were captured, of which 52 were Tom (male), 69 were Queen (female), and 9 were kittens. Regarding their ages, the cats were divided into three groups: <1 year as kittens, 1 to 2 years as young, and adults over two years. Thirty blood samples were drawn from the cephalic or saphenous veins of the hind leg for hematological and serum biochemical analysis.
The findings revealed that the average hemoglobin concentration was significantly higher in kittens than in young and adult cats ( < 0.05). In comparison to young and adult cats, kittens had considerably greater red blood cell, packed cell volume, mean corpuscular volume, and platelet counts, whereas mature cats had much higher white blood cell counts. The number of lymphocytes and monocytes was shown to be non-significant, while other components, such as neutrophils, eosinophils, and basophils, varied considerably by age group. Rural cats showed significantly ( 0.05) higher alanine transaminase and aspartate aminotransferase, whereas urban cats showed higher serum glucose ( < 0.001). The duration of the cat's estrous cycle was (5.63 ± 1.75) days, as were the inter-estrous phase's length (7 days), gestation time (66.6 days), and queening rate (65.2). There were 3.92 ± 0.55 kittens per litter. Males reached puberty at a young age of 9.3 months, while females did so at 8.3 months.
These findings may contribute to the growing body of research on free-roaming cat populations, which is important for understanding the ecology and behavior of these cats and constructing strategies for their conservation and welfare.
开展一项横断面研究，以揭示孟加拉国锡尔赫特地区自由放养猫咪的血液学、血清生物化学及繁殖行为。
总共捕获了130只自由放养的猫咪，其中52只为雄猫，69只为雌猫，9只为小猫。按照年龄，这些猫咪被分为三组：小于1岁为小猫组，1至2岁为青年组，两岁以上为成年组。从后腿的头静脉或隐静脉采集30份血样用于血液学和血清生物化学分析。
研究结果显示，小猫的平均血红蛋白浓度显著高于青年猫和成年猫（<0.05）。与青年猫和成年猫相比，小猫的红细胞、血细胞压积、平均红细胞体积和血小板计数明显更高，而成年猫的白细胞计数则高得多。淋巴细胞和单核细胞数量无显著差异，而其他成分，如中性粒细胞、嗜酸性粒细胞和嗜碱性粒细胞，在不同年龄组中有很大差异。农村猫咪的丙氨酸转氨酶和天冬氨酸转氨酶显著更高（<0.05），而城市猫咪的血糖更高（<0.001）。猫咪的发情周期时长为（5.63±1.75）天，发情间期时长为7天，妊娠期为66.6天，产仔率为65.2%。每窝产仔3.92±0.55只。雄性在9.3个月时达到青春期，雌性在8.3个月时达到青春期。
这些发现可能有助于丰富关于自由放养猫咪种群的研究，这对于了解这些猫咪的生态和行为以及制定保护和福利策略非常重要。
