This study was conducted at Yabello district of Borana zone with the objectives evaluating productive performance 25% Dorper crossbred and local blackhead Somali sheep under agro pastoralists’ conditions, creating awareness, improving knowledge skill. The training given to selected pastoralists, development agents, experts on importance management improved sheep. A total four F1 50% were ...

Objective. The study aimed to characterize the reproductive performances and physical characteristics of Blackhead Somali indigenous sheep breeds. Methods. data from 460 were used for determination morphometric characterization while 110 male 150 females performance Results. Accordingly, about 86% have a white body with blackhead as dominant coat color 81% straight facial head profile. Dewlap w...

Highlights • Parasitic bronchitis (Husk) frequently diagnosed in cattle • Two outbreaks of botulism in cattle and one in sheep investigated • Bovine Babesiosis incidents in North Wales, The South West and Scottish borders • Parasitic gastroenteritis continuing to cause losses in sheep • Cases of acute fasciolosis in sheep provide an early warning of a high risk of disease • Histomoniasis (black...

Sheep and goat have a great role in the economy of the pastoral communities which have inhabited in the lowland parts Ethiopia. The study was conducted in Borana low land southern Ethiopia to predict the body weight of blackhead Somali (BHS) sheep using linear body measurements under farm condition. A total of 478 heads (301 female and 177 males) were measured for linear body measurements and b...

Ovine lymphosarcoma was diagnosed clinically in a 5-year-old Blackhead sheep in Kenya, and confirmed on blood smear, leukocyte count and macroscopic pathology. Four progeny of the ewe were examined. They were normal haematologically but 2 revealed bilaterally enlarged lymph nodes.

The natural form of blackhead, although very fatal to young turkeys, is favorably influenced by treatment with certain of the newer arsenical compounds. Neoarsphenamine injected intravenously in toxic doses has a somewhat favorable effect on the course of the spontaneous disease and evidently lowers the mortality. Its instability, its pronounced toxicity for young turkeys, as well as the diffic...

We determined the polymorphism C242T of the aromatase gene (Cyp19) and its allelic frequency, as well as the effect of the variants on productive and reproductive traits in 71 purebred Santa Inês sheep, 13 purebred Brazilian Somali sheep, nine purebred Poll Dorset sheep, and 18 crossbred 1/2 Dorper sheep. The animals were genotyped using the PCR-RFLP technique. The influence of the animal's gen...

Abstract Galectins are a highly conserved family of β-galactoside binding lectins encoded by lectin, galactosidebinding soluble genes (LGALS). They found on variety cells and tissues vertebrates invertebrates. Understanding the roles galectins in host–pathogen interaction activation host innate, adaptive immunity has become an important research question. known to play role parasitic infection ...

That the ovum of Heterakis papillosa is an important source of the virus in the natural transmission of blackhead in turkeys is suggested by experimental evidence obtained in the present investigation. Confirmatory morphological evidence has not thus far been obtained to establish definitely that this worm serves as the invertebrate host of Histomonas meleagridis. It is possible occasionally to...
