East coast fever is a disease of cattle caused by Theileria parva and is transmitted by the tick Rhipicephalus appendiculatus. Buffalos are a natural reservoir of the parasite. The objectives of this study were to determine the T. parva infection in buffalo and cattle field samples, to identify genotypes of T. parva infecting cattle and buffalo and finally to investigate the presence of buffalo...

Japanese Black cattle occasionally demonstrate growth retardation despite sufficient nutrient intake. To clarify hormonal and transcriptional characteristics, we investigated differences in blood components, including hormones, and differences in exhaustive gene expressions in the liver and peripheral lymphocytes of six cattle with growth retardation (GR cattle) and eight control cattle of the ...

We assessed whether prior foraging by wild herbivores affected foraging behaviour of cattle in Laikipia rangeland, Kenya, during February 2001, August 2001 and February 2002. The study compared cattle bite rate, step rate and bites per step in plots exclusively accessible to cattle and those accessible to cattle and large wild herbivores. During February 2001 when conditions were dry, cattle bi...

The objective of the study is to have a critical review on how indigenous breeds of cattle, their productivity, economic and cultural values affect Nigerians. Present cattle population in Nigeria has been estimated as 15.3 million and breeds of cattle indigenous to Nigeria include White Fulani, Red Bororo, Sokoto Gudali, Adamawa Gudali, Wadara, Azawak, Muturu, Keteku, Ndama and Kuri. A recent s...

BACKGROUND Bovine herpesvirus type-1 (BHV-1) is an important pathogen of cattle that presents with a variety of clinical signs, including the upper respiratory tract infection infectious bovine rhinotracheitis (IBR). A seroepidemiological study of BHV-1 antibodies was conducted in England from 2002 - 2004: 29,782 blood samples were taken from 15,736 cattle from 114 herds which were visited on u...

Controlling the prevalence of Escherichia coli O157 in cattle at the pre-harvest level is critical to reduce outbreaks of this pathogen in humans. Multilayers of factors including the environmental and bacterial factors modulate the colonization and persistence of E. coli O157 in cattle that serve as a reservoir of this pathogen. Here, we report animal factors contributing to the prevalence of ...

AIM We determined the antibody response in cattle naturally infected with brucellosis and normal healthy adult cattle vaccinated during calf hood with strain 19. MATERIALS AND METHODS The antibody titers were measured by standard tube agglutination test (STAT), microtiter plate agglutination test (MAT), indirect hemagglutination assay (IHA), and indirect enzyme-linked immunosorbent assay (iEL...

background : neospora caninum is an intracellular parasite which causes abortion in cattle worldwide.  the aim of this study was to determine the seroprevalence of n. caninum in cattle in babol city, north of iran. methods: blood samples were collected from 237 cattle for determining the seroprevalence of n.  caninum .  a total of 237 serum samples were tested for anti- neospora antibodies.  se...

ABST RACT This study was carried out in order to investigate the presence of Neospora caninum antibodies in local cattle breeds in the Nigde province. The animals used in this study consisted of cattle of at least one year of age slaughtered at a local abattoir in Nigde province of Turkey. Blood samples were obtained from 264 cattle (207 male, 57 female) and serum samples were tested for antibo...

A comparison of the ovarian follicular system in cattle, buffalo and yak yields potentially useful information in developing methods for the improvement of reproduction efficiency in yaks. The ovaries in yaks were generally smaller than in both cattle and buffalo. The histological structures of the yak ovaries and follicular system resembled in all aspects those described for cattle and buffalo...
