A Case Report on Surgical Management of unilateral Cryptorchidism in a Persian Cat
(2023-11) Shahin, Mohammad
Cryptorchidism is a common congenital abnormality in animals, characterized by the failure of one or both testes to descend into the scrotum. This paper presents a case study involving a three year-old Persian cat with unilateral abdominal cryptorchidism, shedding light on the diagnosis, surgical management, and postoperative care. The cat displayed clinical symptoms, including unsuccessful mating, scrotal abnormalities, aggressiveness, and chronic abdominal pain, which raised concerns about cryptorchidism. The condition's incidence can vary across cat breeds, with higher rates observed in Persian cats and Domestic Shorthairs. Diagnosis primarily involves clinical examination and palpation, with the surgeon confirming unilateral cryptorchidism in this case, where one testis remained in the abdomen. Surgical intervention was crucial to address the cat's condition. The procedures performed included abdominal cryptorchidectomy to remove the retained abdominal testis and castration for the scrotal testis. The success of these surgeries highlighted the effectiveness of traditional surgical methods in managing cryptorchidism. Postoperative care is a critical aspect of treatment. The cat was closely monitored for complications, such as sepsis, edema, hemorrhage, and exudates. Daily wound checks and the application of antiseptic cream were part of the care regimen. Antibiotics and anti-inflammatory analgesics were administered over five days to ensure a smooth recovery process. This case study underscores the importance of early diagnosis and appropriate surgical management of cryptorchidism in cats. Timely intervention not only alleviates clinical symptoms but also prevents potential complications, including chronic pain and tumor development. It is noteworthy that advancements in surgical techniques, like laparoscopy, offer minimally invasive alternatives with potential benefits, though they require specialized skills and instruments. As such, continued research and innovations in the field can further enhance the treatment of this common congenital condition in feline patients.
A STUDY ON ESTIMATION OF ENTERIC METHANE GAS EMISSION FROM BUFFALO OF BANGLADESH
(A production Report submitted in partial satisfaction of the requirements for the degree of DOCTOR OF VETERINARY MEDICINE, CHITTAGONG VETERINARY AND ANIMAL SCIENCES UNIVERSITY, KHULSHI, CHITTAGONG., 2023-08) Shahin, Mohammad
This study aims to estimate the enteric methane emissions from buffalo in Bangladesh using different methods, including Tier-1, Tier-2, GLEAM-i software, and the IFCN method. The research is conducted based on the IPCC 2019 guidelines and incorporates data on buffalo population, feed quality, dry matter intake, and methane yield. The results are compared across these methods to understand variations in emission estimates. The Tier-1 method, a simpler approach, estimates methane emissions using emission factors provided by IPCC (2019) and calculated results was 126.31, 126.90, 127.50 and 128.18 Gigagram (Gg) in the year of 2018-19, 2019-20, 2020-21 and 2021-22 respectively. Tier-2 is a more detailed method, considering factors like dry matter intake and feed composition and our calculated value was 114.74, 115.28, 115.82 and 116.44 Gg as the year mentioned in Tier-1. GLEAM-i software, a comprehensive tool, accounts for various parameters at a regional scaleand here we only calculated the baseline 'BDLivstock2020' value 169.63 Gg. The IFCN method, modified Tier-2 method, focused on farm-level emissions, factors in animal categories and production systems. According to IFCN calculation the results are 104.26, 104.75, 105.24 and 105.80 Gg in same year range in Tier-1 and Tier-2 method. The study found that different methods yield varying estimates of methane emissions, highlighting the importance of methodological choices and data accuracy in such assessments.
