A yearlong study was carried out in indigenous cattle of five upazila namely Khagrachari Sadar, Laxmichari, Matiranga, Mahalchari and Dighinala in Khagrachari Hill District, Bangladesh for determination of statuses of various biochemical parameters. Apparently healthy cattle (100) were selected and blood samples were collected aseptically. Biochemical analysis of carbohydrates, proteins, fats, minerals, electrolytes and enzymes were performed by using automated biochemical analyzer (Humalizer ® -3000). The results showed that, the variations of parameters were not significant (p>0.05) between male and female. Although there was a slight increase of calcium (Mean±SEM) 8.01±0.32 mg/dl, glucose 69.21±2.31 mg/dl, LDL 5.69±0.22 mg/dl and uric acid 3.85±0.34 mg/dl of female compared to 7.34±0.42, 68.32±1.81, 5.05±0.25 and 3.37±0.27 of the male. On the other hand, SGOT (100.14±4.86 U/L) was slightly higher in male compared to the female (91.97±5.55). There was a slight variation in ALP (218.81±29.12 U/L) of growing cattle compared to the calf's (293.57±42.78) and production cattle (300.88±27.24), although the variation was not significant (p>0.05).

:The study was carried out in Chittagong Veterinary and Animal Sciences University (CVASU), Chittagong to find out the causes of sudden death of cattle in the Military Dairy Farm, Chittagong. To explore the cause of death, clinical history, clinical signs were recorded. Finally, postmortem was done and samples were collected for laboratory diagnosis. The ruminal pH was 9.0 and the clinical history along with signs suggests possible non-protein nitrogenous compound poisoning. The laboratory diagnosis coincides with nitrate poisoning which focuses possible relationship between non-protein nitrogenous compound and nitrate poisoning. The study recommends maintaining proper cautions to use urea in concentrate feed.

The study was conducted to study the effects of genotype and age of hen and hatching season on hatchability of egg. Hatching eggs were collected from hens having three genotypes viz. White Leghorn (WLH), Rhode Island Red (RIR) and Fayoumi covering three age groups (28 to 40, 41 to 60 and 61 weeks & above) at winter, monsoon and summer seasons. The study revealed that the highest (P<0.05) average hatchability was observed in winter (78.62%) followed by monsoon (76.70%) and summer (75.79%). Among different genotypes the highest (P<0.001) hatchability was found in Fayoumi (78.34%) followed by White Leghorn (76.48%) and Rhode Island Red (74.59%). Considering the age of hen, highest (P<0.05) hatchability was found in the age group between 41 to 60 weeks (77.99%) followed by 61 weeks and above (76.49%) and 28 to 40 weeks (75.71%) of age. From the findings it can be concluded that the winter season was suitable for hatching of eggs and the performance of Fayoumi hen was better in terms of hatchability of egg. On the other hand, the age of hen between 41 to 60 weeks was better for producing hatching eggs. DOI: http://dx.doi.org/10.3329/bjas.v37i1.9863 BJAS 2008; 37(1): 17-22

Hematology and serum chemistry values were obtained from 28 male and 22 female stray dogs in Chittagong Metropolitan area, Bangladesh. The goal of the study was to establish reference value for hematology and serum chemistry for these semi wild animals in relation to age, sex, reproductive stage and body condition. No significant differences were found for mean values of hemoglobin, packed cell volume, mean corpuscular hemoglobin concentration, white blood cell, differential leukocyte count, total protein, albumin, glucose, cholesterol, phosphorus and potassium among or between sexes, ages, reproductive states or body conditions. Significant differences were noted for erythrocyte sedimentation rate (p<0.02) between sexes. Among different age groups significant differences were found for total red blood cell count (p<0.001). Different body conditions have significant differences in red blood cell count, mean corpuscular volume and mean corpuscular hemoglobin (p<0.001). Pregnant and non-pregnant females differed significantly in their red blood cell count, mean corpuscular volume and mean corpuscular hemoglobin (p<0.001).

Climate change nowadays is a global threat that is driven by human-induced greenhouse gas emissions and the changeable pattern of global weather. Though there have been previous periods of climatic change since the mid-20th century, humans have had an unprecedented impact on earth’s climate system and caused change on a global scale. Consequently, this is affecting the whole food system throughout the world. The utilization of the international legal framework and protocols will have an impact on the human’s food system and livestock production. This paper intends to focus on using legal frameworks and protocols to erase the impact of climate change on the food system and livestock production. By using the quantitative research method due to the pandemic situation, this study will explain the broad uses of the Kyoto protocol and Polluter Pays Principle and shall discuss various methods that will help these principles to erase the negative impact of climate change globally. Based on the findings, this paper provides recommendations that could be considered by the developed country to use the legal and social protocols for improving the impact of climate change on the food chain system of humans and livestock production. Abstrak Perubahan iklim saat ini merupakan ancaman global yang didorong oleh emisi gas rumah kaca yang disebabkan oleh manusia dan perubahan pola cuaca global. Meskipun telah terjadi periode perubahan iklim sebelumnya, sejak pertengahan abad ke-20 manusia telah memberikan dampak yang belum pernah terjadi sebelumnya pada sistem iklim Bumi dan menyebabkan perubahan dalam skala global. Akibatnya, ini mempengaruhi seluruh sistem pangan di seluruh dunia. Pemanfaatan kerangka hukum dan protokol internasional akan berdampak pada sistem pangan manusia dan produksi ternak. Makalah ini bermaksud untuk fokus pada pemanfaatan kerangka hukum dan protokol untuk menghapus dampak perubahan iklim terhadap sistem pangan dan produksi ternak. Dengan menggunakan metode penelitian kuantitatif karena situasi pandemi, penelitian ini akan menjelaskan penggunaan yang lebih luas dari protokol Kyoto, Polluter Pays Principle dan akan membahas berbagai metode yang akan membantu prinsip-prinsip ini untuk menghapus dampak negatif perubahan iklim secara global. Berdasarkan temuan makalah ini memberikan rekomendasi yang dapat dipertimbangkan oleh negara maju untuk menggunakan protokol hukum dan sosial untuk meningkatkan dampak perubahan iklim sistem rantai makanan manusia dan produksi ternak.
