Background and objective: Coccidiosis is caused by a protozoan parasite of the genus Eimeria and affects poultry industries worldwide. This study was conducted to evaluate the impact of C. aegyptiaca ethanolic extract on broiler chicken coccidiosis.

Methods:Six groups of chicks in a complete randomized design were used for the study. Each chick among five groups was orally challenged with 2 × 10⁴ Eimeria tenella sporulated oocysts. The first three groups received the decoction of C. aegyptiaca orally at 400, 200 and 100 mg/kg respectively, while the fourth group received anticox. The fifth group was the negative control. Chickens were sacrificed at the end of the treatment and haematological parameters such as white blood cell count, lympocytes, red blood cell count, hemoglobin, hematocrit and platelet count were determined using an automatic counter. For carcass performance, the chickens were weighed after de-feathered with and without internal organs (non-conventional and conventional yields respectively). Meat samples were collected from the thigh muscles and chest for the evaluation of chemical and technological properties.

Results: There was a significant improvement on the haematological (red blood cells, platelets, white blood cells and differential counts, haemoglobin, hematocrit and mean corpsular volume) and carcass (chemical and technological) parameters, especially in the IME400 mg/kg, positive and the normal control compared to the negative control.

Conclusion: Results from this study could be used for developing phytoelements that can serve as an alternative to synthetic anti-coccidial drugs.

A cross sectional study was carried out from November 2017 to December 2017 to assess the status of subclinical mastitis in Ejersa lefo District Oromia region Ethiopia. Study animals were selected using simple random sampling technique. Out of 384 examined (Borena 9, cross breed 45 and local breed 330) 111 cow were found to be affected with subclinical mastitis with prevalence of 28.9%. The result from the severity grading of the infection indicates that out of 111 positive cows 70 (63.3%) cows had weak infection, 17 (15.3%) had distinct positive and 24 (21.6%) cows had strong positive infection. The highest occurrence of subclinical mastitis was recorded in local breed (82.9%), old age group (83.7%), sixth parity (36%), and first lactation stage (36.9%). Cows having poor teat hygiene and kept in poor barn hygiene were 82% and 79.5% infected with subclinical mastitis. In this study subclinical mastitis was major mammary gland health problems of the dairy cows, which cause huge loss of milk production that assure serious attention in creating awareness and prevention strategy.
