The Parasight

Description: this month, Ben covers the common causes of sudden death in lambs, from intestinal torsions and abscesses to pneumonia and coccidiosis. He also discusses sudden deaths in ewes at this time of year, including haemonchus and grass staggers, outlining ways to help prevent these conditions. Finally, he looks at several cases of sudden death in calves.

Description: this month, Ben talks through two real cases where sheep were treated for suspected fluke using the wrong product, outlining the consequences and the issues that arose. He highlights why it’s so important to correctly identify the parasite before treating, and shares a timely warning on coccidiosis and nematodirus in lambs. Finally, he explains why adequate dietary protein is essential for pregnant suckler cows.

Description: this month, Ben explains the key areas to consider before lambs and calves are born, helping to give them the best possible start in life. He then highlights several important watch-outs when dealing with dummy calves. Ben also covers the common causes of infectious abortion in sheep, outlining practical steps that can help prevent them in future seasons. Finally, Ben explains the importance of submitting placentas for abortion diagnosis.

Description: this month, Ben breaks down seasonal pasture risk levels based on recent sheep and cattle activity and explains the associated worm risk. He follows this with strategies for making the most effective use of low-risk pasture. Ben then explains how worm larvae can survive a hot, dry summer and outlines practical ways to manage this risk before the rain arrives. He goes on to highlight key points to consider when scanning thin ewes and hoggs. He also covers a few watch-outs for pneumonia in cattle and strategies to help prevent it. Finally, Ben shares important considerations when dealing with moudly bales.

Description: this month, Ben explains how the recent change in weather is affecting worm burdens on pasture, including the potential treatment options to use during this period. He then describes when shearlings develop immunity to worms and the various factors this depends on. Ben also discusses a case of fluke in a ewe and the importance of testing rather than routinely treating animals. Finally, he talks about making the transition to housing calves as smooth as possible and highlights the growing issue of wormer resistance in cattle.

Description: this month, Ben discusses the rise in cases of pasteurellosis in lambs. He explains the causes of pasteurella infection and the various stress factors that can worsen its effects. He then talks through the correlation between worms and pasteurellosis. Ben also highlights the risk of acorn poisoning for grazing livestock this autumn. Finally, he shares key considerations for managing lambs going away on winter keep and gives a reminder about quarantine drenching all incoming sheep.

Description: this month, Ben highlights key watch-outs with haemonchus, discussing a case he recently reviewed. He then goes on to explain the difference in growth rates between lambs that have been wormed and those that haven’t. After, he covers various strategies for maximising lamb growth rates. Finally, he discusses a few cases where stock died from consuming poisonous plants, emphasising important considerations.

Description: this month, Ben emphasises how weather patterns influence disease risk and provides an update on how current conditions are affecting parasite activity. He reports a high number of Haemonchus cases in certain areas across the country and outlines the key signs to look for during a post-mortem. He stresses that each farm is different, and that specific farm issues should be considered before selecting treatment options.

Ben also shares a few recent cases of Nematodirus in lambs and discusses how to respond, depending on post-mortem findings. Finally, he explains the link between grass length and worm risk in lambs and discusses options for managing that risk.

Description: this month, Ben covers a few cases of mastitis in ewes, discussing contributing factors, treatment options, and the impact on lamb growth rates. He then explores the causes of poor lamb growth, strategies to prevent it, and how this can affect future worm burdens.

Ben then covers how current grass growth is influencing worm burdens and the resulting impact on lamb performance, along with the diseases that can arise during periods of increased grass growth. Finally, he discusses a case in which two seemingly healthy lambs died unexpectedly and explains how targeted WEC monitoring can help prevent similar losses.

Description: this month, Ben discusses two cases highlighting the importance of timely diagnostics and worm control in cattle.

In the first case, a group of spring-born calves were found to have a low worm burden following a composite worm egg count test. However, by mid-March, three calves began to lose condition. All were treated with a wormer, but one died shortly after. Post-mortem findings revealed type 2 ostertagiasis. This is followed by a discussion on the watch outs of worm egg count tests and other diagnostic options available.

Ben also covers a case involving bought-in heifers, which were wormed one month after housing. One died ten days after calving. A post-mortem revealed adult lungworms, raising concerns about potential anthelmintic resistance.

Description: This month, Ben first covers why lambs are dying from starvation and chilling. He then goes on to explain the current situation with coccidiosis and nematodirus in lambs, including when to watch out for them. Finally, Ben discusses a 200-ewe flock diagnosed with haemonchosis, highlighting how this parasite might be adapting to become more cold-tolerant and pose an early-season threat the following year.
