Overview

OVERVIEW There was a slight increase in commercial broiler placings in the UK compared with the same quarter last year and also an increase in broiler parent placings. However, broiler margins are being squeezed at present as a result of both competition and increased feed (cereal) prices. Turkey poult placings are at a higher level than the same quarter last year and commercial layer chick placings from UK hatcheries are continuing the rise seen last year (poultry statistics page 2).

The overall health status of the industry remains reasonably good. This report provides updates on some of the current health issues affecting the industry including IB variants in layers, gizzard erosion in broilers and unevenness in broilers. Many health problems affecting the industry are multifactorial and include both infectious agents and other, non-infectious factors. There have been no reports of histomoniasis (blackhead) in turkeys or other species during the quarter.

Mycoplasmosis continues to be prevalent in the industry, particularly M.gallisepticum in layers, as reported in the previous quarterly report. The report summarises a new technique for Mycoplasma diagnosis which will be available through the VLA in the summer.
