Abstract [+]
Aim
The study was conducted to determine the prevalence of hydatidosis, to identify the association between expected risk factors and occurrence of the disease, to investigate economic importance and to evaluate fertility and viability of the hydatid cyst in cattle slaughtered at the abattoir.
Materials and Methods
A cross-sectional study, which involves both ante-mortem and post-mortem examination, was conducted at Nekemte municipal abattoir from November 2015 to March 2016.
Results
A total of 355 local cattle breed was randomly sampled and examined for the presence of hydatid cysts in the organs of the animals using the standard meat inspection procedures, 66 (18.6%) animals were found harboring hydatid cysts. Statistical analysis showed that there was a significant difference (p<0.05) between the prevalence of bovine hydatidosis in all risk factors with exception of sex of the animals. Among 207 hydatid cysts recorded, 93 (44.92%) were from lungs, 65 (31.40%) from livers, 4 (1.93%) from heart, 3 (1.44%) from kidney, 1 (0.48%) from spleen and 41 (19.8%) were in two organs from lung and liver. Fifty-seven (57) of these 207 cysts were randomly selected and subjected to fertility and viability test which revealed 19 (33.33%) as fertile, 25 (43.86 %) sterile and 13 (22.81%) calcified. Viability test proved 7 (12.28%) of 19 fertile cysts as viable and 12 (21.05%) of 19 fertile cysts as non-viable. Viability of cysts in different organs revealed that 5 (16.1%) and 2 (10%) of cysts from lungs and liver, respectively. The estimated financial loss during the study period both due to condemnation of organs and an in direct carcass weight loss from hydatidosis was 2,190,143.52 ETB.
Conclusion
The results of this study revealed that bovine hydatidosis was an economically important disease of cattle which need serious attention for prevention and control actions in and around Nekemte. Hence, establishment of well-equipped standardized abattoirs, prohibition of backyard slaughter, creation of public awareness, deworming and control of stray dogs are of paramount importance.

Abstract [+]
Nanoparticles are small and have a large surface-to-volume ratio, which gives them phenomenal, unique features. It is an emerging, multidisciplinary field that frequently employs new techniques and tools from diverse disciplines, including biology, engineering, chemistry, and medicine. Nanotechnology entities help to improve the solubility, absorbability, bioavailability, and half-life of conventional natural products. Nano-applications are used in poultry and animal production systems using available tools and techniques without affecting animal health and welfare. Nanotechnology is a smart technology in the field of biomedical engineering used for the diagnosis and treatment of different poultry diseases. This technology provides better solutions for
various applications and poultry production that can help in reducing costs and improving the final product quality. Even though nanotechnology is one of the main novelties which have already been applied in poultry and other different areas, it is still in the initial stages of its development and it hampers the environment, animal, and people’s health. Therefore, wide hazard assessments should be conducted to ensure the safety of the nanoproducts before making them immediate implementation for poultry/animal/or human use.

Abstract [+]
Reproduction is one of the key pillars of production in many herds and individual animals. In female animals, reproduction can be affected by uterine diseases including metritis and endometritis. The objective of this review is to understand metritis and endometritis, diagnosis and treatment approaches, and the economic impact of uterine inflammations. Metritis is inflammation of the wall of the uterus, whereas endometritis is inflammation of the functional lining of the uterus, called the endometrium. Clinically, they are characterized by an enlarged uterus containing a watery red-brown fluid to viscous off-white purulent uterine discharge, which often has a fetid odor within 10 to 14-days after postpartum period in clinical metritis whereas clinical endometritis can also be observed its clinical signs after 21-days postpartum period. The risk factors for the occurrence of clinical metritis and endometritis include extrinsic factors include calving season and nutrition whereas intrinsic factors include retained fetal membrane (RFM), dystocia, metabolic disturbance, negative energy balance (NEB) and other non-specific diseases. These factors disturbing the normal physiology and weaken the immune system of dairy cattle. The factors favor the multiplication of pathogenic bacteria and cause inflammation of the uterus and results in metritis and endometritis. This result in increased conception interval increase the number of inseminations, loss of milk and meat production, marked drop in fertility and increase the cost of treatment. Clinical metritis and endometritis can be diagnosed by clinical symptoms and cytological examinations. Clinical metritis and endometritis can be treated by anti-inflammatory drugs flunixin meglumine, antibiotics (pens-trip and long-acting oxytetracycline), intrauterine infusion by using saline or iodine tincture solutions. Clinical metritis and endometritis are the most frequent uterine disorders in dairy cows causing decreased fertility leading to high economic losses. Therefore, management of these production diseases can be achieved by early diagnosis and treatment, supplementation of balanced feed containing minerals, vitamins, appropriate proteins and carbohydrates, good quality management during and after calving of the female animals.

Full-Text (HTML)
Abstract [+]
Organic livestock farming is a useful strategy to overcome the challenges of the agricultural sector like sustainability, food security, and food safety while matching with a high status of animal welfare, care for the environment, restricted use of medical drugs, growth promoters, synthetic fertilizer and the production of healthy food products without drug residues. Furthermore, organic livestock farming could also be an interesting strategy for the eternal rural development issue and solution for the farms’ decreasing profitability. The regulation of organic animal production is comprehensive and affected by different aspects such as feeding, housing, breeding, health care, and medical treatment. In contrast to conventional production systems, animals under organic livestock production are allowed a larger housing area, have obligatory straw bedding, fed organic feed, and roughage. The animal feed is a strong determinant of the fatty acid composition of the milk, egg or meat. In relation to animal health and welfare, the application of breed selection, good management, nutrition, and husbandry plays a greater role in disease prevention and good animal welfare. Now-a-days, antimicrobial resistance is a global public health issue and a threat to the modern health care system which is recognized by many international health organizations. Accordingly, over the last few years, the demand for organic products and availability in the market has been increased and made significant development in the economy. Several people have started to consider organic food instead of conventional food because it is healthier and less prone to the impact of chemical residues. Consequently, awareness creation and encouraging the importance of organic products for customers is important for the development of organic production.

Abstract [+]
Prolonged pregnancy is defined as a pregnancy that lasts for more than 294-days compared with term gestation which is between 260 and 293-days. This case report was prepared with the aim of describing and documenting the surgical procedures, techniques of cesarean section and its outcome on eight-years-old crossbred cow that was referred to the veterinary hospital, Mekelle University from a field; Edaga Hamus Veterinary Clinic. According to the owner’s history, the cow was presented to the clinic with an extended gestational period over 345-days than anticipated according to their own record. Thus, based on the history and clinical findings, the case was diagnosed as prolonged pregnancy. After aseptic preparation of the surgical site, stabilizing the animal and locally desensitizing the incision area; a vertical skin incision with a distance of approximately (~40 cm wide) on the left flank region approximately (~10 cm) below the lumbar transverse process. After the incision of the abdominal muscles and uterus, the non-viable and abnormally oversized calf was taken out with the help of an assistant. Moreover, the uterus was filled with excess and abnormal dark brown colored blood and was properly drained, washed with sterile isotonic saline solution. The uterus was closed using a double layer of Utrecht suturing pattern whereas the peritoneum and abdominal muscles were separately closed with a continuous lockstitch pattern and simple interrupted pattern using 2-0 size sterile absorbable polyglycolic acid, respectively. After that, the skin was closed using silk 2-0 size in a horizontal interrupted mattress. Lastly, with proper antibiotic follow-up, dressing and cleaning of the surgical site, the cow was successfully recovered after two months.

Abstract [+]
Aim
The objective of this study was to assess the major welfare problems in working donkeys in Hosaena district, Hadiya Zone, Southern Ethiopia.
Methods and Materials
A total of 318 male and 76 female working donkeys were randomly selected using a cross-sectional study from November 2015 to April 2016.
Results
According to the current investigation, 70% of donkeys were used for draught and 30% were used for pack type of work. All females (100%) were used for packing purpose, whereas 86.8% of male donkeys were used for draught purpose. Overall, 41.6% of donkeys had a poor body condition in all age groups, whereas most donkeys (44.3%) under the age group less than 5-years were having poor conditions. Regarding wound on the skin, a higher proportion (82.2%) of back lesions were observed in pack donkeys whereas lip lesions were observed in 87.7% of draught donkeys. Besides, the welfare problem was observed in 28.9% of working donkeys due to overloading. A significant association (p<0.01) was found between the duration of working hours of donkey and poor body condition. Out of the interviewed, the majority of animal owners (76.4%) had one donkey.
Conclusion
The assessment showed that working donkeys in the present study area were experiencing multiple welfare problems. Accordingly, awareness creation through mass education, training and extension service should be promoted in the study area in order to ensure better donkey welfare and productivity.

Full-Text (HTML)
Abstract [+]
A Holstein Friesian (HF) crossbred dairy cow of 5-years-old and 38.5-weeks pregnant was presented to the Veterinary Hospital of College of Veterinary Science, Mekelle University with a history of repeated prolapse since last 10-days. Upon clinical examination, the case was confirmed as prepartum cervico-vaginal prolapse due to excess labor and straining to deliver the fetus. After caesarean section, the cow was restrained on sternal recumbency and the prolapsed mass was made aseptic by washing with a 2% potassium permanganate solution and was repositioned into the pelvic cavity. The cow was kept on fluid therapy (stat), antiinflammatory and antibiotic for three successive days. A modified Buhner’s technique, using infusion set tube as suture was to keep the prolapsed tissue in position to prevent the recurrence and the cow had an uneventful recovery. A successful management of recurrent prepartum cervico-vaginal prolapse using modified Buhner’s suture after caesarean section in a crossbred Holstein Friesian dairy cow is discussed.
