This is week 2 of the FW/Merial Christmas competition to win three £2500 computers plus

software. Just read the text, answer the question and fill in the coupon in the Jan 4 issue

WHY should farmers be concerned about fluke? Last week we told you that it was on the increase, with DEFRA reports showing an increase in the incidence of the disease of around 400% in the past four years.

Fluke can seriously damage your cattles performance. By damaging the liver, it impairs feed efficiency and results in reduced conception rates, weight gains and body condition.

The disease is certainly more serious than at first it may seem. For example, for each adult, fluke can cause the loss of 0.5ml/blood/day, the reason that so many infected cattle become anaemic. Infected livers can become permanently damaged, resulting in condemnation at the slaughterhouse.

In cattle this scarring can lead to calcium deposits in the walls of the bile ducts, leading to a condition known as pipestem livers, which can cause knives to be blunted when the liver is cut through.

As this disease affects both cattle and sheep, the mixed grazing of these animals is not recommended in fluke areas during high risk periods. Sheep are more prone to the acute form of the disease which can be fatal. Cattle rarely suffer acute disease, they suffer chronically, causing a loss of productivity and ill-thriftiness.

Although youngstock tend to be more susceptible than adult stock, fluke are no respecter of age. An immune response of sorts is triggered, but is not fully protective and adult cows (dairy and sucklers) can be affected.

Fluke-infected animals can also be more prone to serious bacterial disease, for example, salmonellosis in cattle and Black disease (a fatal Clostridial disease) in sheep.

Question 2

How much can liver fluke infection reduce weight gain by in cattle?

A – 8%

B – 28%

C – 88%

Keep a copy of your answer and use it to fill in the coupon in the Jan 4 issue
