This video documents the treatment of a severe "white line problem" in an Aberdeen Angus beef cow, exacerbated by fly strike and a significant infestation of larvae within a hoof crack. The procedure, performed within a cattle crush, involves an initial routine hoof trim to ensure balanced weight distribution. A supportive block is then applied to the healthy claw to offload pressure from the affected area, allowing it to cure during further treatment steps. The core of the treatment focuses on meticulously cleaning the lesion by jetting out larvae with chlorhexidine and carefully removing compromised hoof horn. The video underscores that such hoof ailments and fly strike are natural occurrences, not indicative of agricultural mismanagement. Post-treatment, the cow is released without bandaging, relying on air exposure and a topical fly-deterrent spray for healing and prevention of re-infestation, with the block providing immediate pain relief and promoting recovery.
Treating a Cow's Hoof: Addressing Fly Strike and White Line Problems
0:00 Introduction to Fly Strike: The video highlights the prevalence of fly strike and larvae infestation in cows, particularly at certain times of the year, leading to discomfort for animals like the Aberdeen Angus cow shown in the crush.
0:35 Understanding the Problem: The cow's issue is identified as a "white line problem," a natural hoof crack resulting from injuries like stepping on stones or fighting, which then becomes a breeding ground for fly larvae. This is presented as a natural cycle, not an indication of poor farming.
1:45 Hoof Assessment: Before treatment, the hoof's overall good condition is noted, but one claw is observed to be unnaturally high, indicating the cow's attempts to avoid putting weight on the injured part.
2:03 Routine Trim and Block Application: The treatment begins with a standard hoof trim to level and balance the claws, ensuring even weight distribution. A supportive block is then prepared and carefully glued to the healthy inner claw to transfer weight away from the damaged area, with a caution against singeing the hoof horn during this process as it can weaken glue adhesion.
3:27 Larvae Removal and Cleaning: Chlorhexidine is sprayed with a strong jet to dislodge and remove the larvae from the hoof. The primary goal is to remove the cracked and infected hoof horn, which naturally brings the larvae out.
5:20 Post-Cleaning Treatment: After thorough cleaning, a topical spray is applied to the lesion to promote healing of the hoof horn and provide relief. The block plays a crucial role in reducing pain by redistributing the cow's weight.
5:50 Cow Release and Recovery: The cow is released without any wrapping on the hoof, as open-air exposure is deemed beneficial for healing. The applied spray is expected to deter further fly activity, and the cow shows immediate improvement in mobility, walking comfortably onto a straw pen.
