Stomoxyines are mechanical vectors of several pathogens of livestock with severe consequences such as low productivity from constant irritation and disturbance. In vitro and in vivo bioassays were conducted to confirm the efficacy of cypermethrin analogues on stomoxyines. Cattle treated with cypermethrin (Pantex 30 g l-1 ) and cypermethrin-mix (cypermethrin + oil from Senna occidentalis locally prepared by Fulani herdsmen) were compared using the restricted insecticidal application (RAP) method and a local Fulani application approach (FAA), while untreated cattle serve as control...

Fifteen apparently healthy Kandari cross-bred cattle aged about 4 years were purchased from Rurki, Patiala district of Punjab by a private dairy farmer in Erode, Tamil Nadu. Four animals showed eruptions on the lateral thoracic and dorsal abdominal regions of the body after 15-day period of quarantine. Manual palpation of the eruptions resulted in the emergence of larval stages of dipteran flies, identified by their morphology as Hypoderma from these animals. Molecular identification based on mitochondrial cytochrome oxidase-1 (COX-1) gene confirmed it to be Hypoderma lineatum...

The projected human population growth of 9 billion by the year 2050 has placed greater demand on food security. This calls for an increased supply of foods, especially of animal origin in order to prevent food scarcity in the future. Poultry which would have been a solution to this increased demand for foods of animal origin had suffered from the rising costs of conventional feed ingredients, and this emphasizes the interest to develop local feedstuffs. In view of this, there is increased interest by livestock farmers especially in developing countries to harness the potential of leaf and seeds of tropical browse plants...

Bovine brucellosis is a zoonotic disease that causes great economic losses. The disease is endemic in Colombia and animal movements from infected herds carry a risk of introduction to other herds. With the objective of analyzing the animal movements and determining their relationship with bovine brucellosis, we performed a descriptive analysis of the space-time movement of livestock in Colombia between 2006 and 2014. Multiple linear regression models (MLR) were employed to determine the relationship between brucellosis status and animal movements at the province level...

This paper examines factors influencing the adoption of alternative response to Foot and Mouth Disease (FMD) among smallholder beef producers in the dry lands of Africa, specifically, North East district in Botswana. Principal component analysis was used to categorise FMD responses. Thereafter, a multivariate probit regression model was used to examine the effect of socioeconomic and institutional factors on the adoption of alternative responses to FMD. The study found that household size, opportunity cost incurred, frequency of contact with extension officers, training received on FMD, distance to the nearest market, as well as distance to grazing and water areas had a positive effect on the adoption of alternative responses to the outbreak...
