To cite: Povey H, Cameron D. Thorax 2013;68:1175. A family of four from North Wales had a miserable Christmas. Their misfortune began in early December with the sudden death of their two pet lovebirds within 24 h of each other (figure 1). Over the Christmas period they suffered further adversity as the mother developed a flu-like illness with generalised body aches, lethargy and worsening of he...

Two experiments were conducted to evaluate the effects of a complex Lactobacilli preparation on performance, resistance to E. coli infection and gut microbial flora of weaning pigs. In exp. 1, twelve pigs (7.65±1.10 kg BW), weaned at 28 d, were randomly allotted into 2 groups and placed in individual metabolic cages. During the first 7 d, one group of pigs was provided ad libitum access to wate...

Article history: Received 4 August 2007 Received in revised form 2 May 2008 Accepted 19 May 2008 We investigated tissue fatty acids (FA) profiles, systemic and portal plasma biochemical characteristics, and cecal digesta biogenic amines in piglets fed diets containing flaxseed (FS) and a multi-carbohydrase enzyme supplement (C). Enzyme supplement provided 500 U pectinase, 50 U cellulase, 400 U ...

Ammonia (NH3) emissions originate predominantly from manure. In outdoor pig production, excretory behaviour creates nitrogen (N) point loads. This study examined ammonia losses from pigs on grassland at two farms by calculating N field balances per pen and sub-areas preferred (P) and not preferred (NP) for excretion. Spatial variation in ammonia losses was measured with an equilibrium concentra...

Food plots are a vital element for the survival of game bird species such as bobwhite quail (Colinus virginianus) on Fort Riley Military Installation in Kansas. However, white-tailed deer (Odocoileus virginianus) tend to eat the sorghum when it starts to ripen in September and continue feeding on it through November and December, often leaving no food for the quail during the winter. We conduct...

The advent of antimicrobial drugs has brought the significance of the tuberculin test in sharp focus. This test determines the magnitude of the tuberculosis problem in groups of people since it readily detects those who are harboring tubercle bacilli. Evidence is accumulating which suggests that the clinical tuberculosis of the future will occur largely in those now infected. Only the tuberculi...
