Eprinomectin in Dairy Zebu Gobra Cattle (Bos indicus): Plasma Kinetics and Excretion in Milk

Parasitology Research, 2006
The pharmacokinetics and mammary excretion of eprinomectin were determined in zebu Gobra following topical administration of 0.5 mg kg(-1). The kinetics of plasma and milk was analysed using a one-compartment model. The maximum plasma concentration of 8.83+/-2.15 ng ml(-1) occurred 1.30 days post-administration.

Effect of Controlling Natural Field-Tick Infestation on the Growth of N'Dama and Gobra Zebu Cattle in the Gambia

Preventive Veterinary Medicine, 1998
The effect of tick infestations on liveweight gain (LWG) was assessed by comparison of weight changes in flumethrin-treated N'Dama and Gobra zebu cattle (16-20 months old) with respective control groups submitted to natural tick challenge over 1 year. Flumethrin was applied monthly, fortnightly or weekly.

Trypanosome Infections and Tick Infestations: Susceptibility in N’Dama, Gobra Zebu and Gobra×N’Dama Crossbred Cattle Exposed to Natural Challenge and Maintained Under High and Low Surveillance of Trypanosome Infections

Acta Tropica, 1998
Susceptibility to trypanosome infections and tick infestations was assessed in 51 N'Dama, 48 Gobra zebu and 37 Gobra x N'Dama crossbred (F1) cattle exposed to field-tick infestations and natural high tsetse challenge over more than one year. From these cattle, 12 animals of each breed were randomly selected and examined parasitologically for ...

Simulated Effects of Changing Strategies on Production Performance of Gobra Zebu Cattle

Agricultural Systems, 1987
Abstract Analyses of various management strategies available for the production of Gobra Zebu cattle at Dahra Research Station were conducted using a dynamic cattle production simulation model. Growth, milk production, forage and management characteristics collected at the station were the major input data used.

Haematological Changes in N'Dama and Gobra Zebu Bulls During Trypanosoma Congolense Infection Maintained Under a Controlled Feeding Regimen

Acta Tropica, 1998
Haematological changes were monitored in Gobra-Zebu and N'Dama bulls following infection with Trypanosoma congolense. The cattle were offered a diet which provided levels of protein and energy above maintenance requirement and a pair feeding regimen was used in order to eliminate the confounding anorexic effects of trypanosomosis on the traits studied.

Susceptibility to Different Tick Genera in Gambian N'Dama and Gobra Zebu Cattle Exposed to Naturally Occurring Tick Infestations

Tropical Animal Health and Production, 1995
Tick collection on one side of the body and whole tail was performed weekly over one year on 11 Gambian N'Dama (Bos taurus) and 11 Gobra zebu (Bos indicus) cattle to assess breed susceptibility to naturally occurring ticks. Enzyme-linked immunosorbant assay was also performed to assess the serological prevalence of Anaplasma marginale antigen and ...

Analysis of growth curve parameters of Gobra zebu females in Senegal

Tropical Animal Health and Production, 1987
Analysis of growth curve parameters was performed using body weight data collected from 1968 through 1980 at Dahra Research Station, Senegal. Month of birth had little or no effect on mature size and maturing rate. Females born from mid-wet through mid-dry seasons were likely to reach lighter mature weights than those born from mid-dry through mid-wet ...

Immunogenetic Influences on Tick Resistance in African Cattle With Particular Reference to Trypanotolerant N’Dama (Bos taurus) and Trypanosusceptible Gobra Zebu (Bos indicus) Cattle

Acta Tropica, 2000
In sub-Saharan Africa, tick infestation and tick-borne infections together with tsetse-transmitted trypanosomosis arguably constitute the main parasitological disease complex constraining livestock production. Resistance to tick attack and tick-borne micro-organisms (TBMs) varies among different breeds of cattle.

Effects of Poor Pasture Conditions and Type of Feeding on Some Biochemical Values of Gobra Zebu in Senegal

British Veterinary Journal, 1991
Blood samples were obtained from 70 healthy gobra zebu from three different farms each one with a different feed (natural pasture, concentrates and groundnut hay) to exhibit the influence of type of feeding. To evaluate effect of poor pasture conditions, animals in an extensive system on natural pasture were sampled twice with a monthly interval in the

A Comparative Study of the Parasitological Buffy Coat Technique and an Antigen Enzyme Immunoassay for Trypanosome Diagnosis in Sequential Trypanosoma Congolense Infections in N'Dama, Gobra Zebu and N'Dama x Gobra Crossbred Cattle

Acta Tropica, 1996
The buffy coat/dark ground techniques (BCT) and an antigen enzyme immunoassay (Ag-ELISA) were compared for the diagnosis of trypanosome infection in N'Dama, Gobra zebu and N'Dama x Gobra (F1) crossbred cattle following two sequential experimental Trypanosoma congolense infections.
