A producer recently approached me after starting to question the ultimate success rate of the footbath method. He was also wondering how to measure the return on investment (ROI). Despite having used the footbath frequently, he still had an unacceptable rate of lameness in his herd. I would like to explore the issue further in this article. I’ve split the topic under several headings to provide a better overview.

1. The method itself: the use of the footbath

The dairy industry has been using the footbath method for over 40 years. It has recorded both positive and negative experiences over this period.Hoof-Sol Bath pouring

  • On a positive note, the footbath has a definite place in a lameness prevention program. When dairies use their footbaths properly and clean them regularly, they have a valuable asset. However, the most important aspect is not the footbath itself but the records that go with its management. Someone should be in charge of monitoring lameness at any given time. This person should record the cause and treat the individual animals by trimming or wrapping their feet. The process should also include follow-ups to check whether the animals have recovered. Use these records to fine-tune your footbath protocol and thus optimize lameness prevention.
  • Many see foot bathing as a “time-saver.” They argue that “there are only 24 hours in a day and we cannot always take care of our lame cows.” Research has shown that, at any given time, 25-30% of cows in North America are lame. This figure indicates that the footbath method is not sufficiently effective and there are some challenges to overcome.
  • Footbaths often serve as a method to treat lameness instead of being part of a prevention Intra Bathapproach. When the herd is showing some lameness, is it fair to assume that the cause is always an infectious disease (foot rot, heel warts, etc)? Putting a footbath in place and religiously use it for a while, will that do the trick? Really, what is the cause of lameness? The use of a footbath can’t “fix” or prevent all lameness. Do you have a plan in place for the cows that remain lame even after the extensive use of any footbath method? It would be better to treat all lame cows before you run a footbath program. This gives you some benchmarks to judge the success of the footbath over a period of time. It also provides a focus for taking care of the causative factors in a more effective way, either by adjusting foot bathing protocols or trimming frequency.
  • The footbath gets dirty very fast so the first cows get the benefit and the last ones have to walk through the grimy solution. As a matter of fact, your lame cows, which are the slower group, are those that end up with the most contaminated bath. At the same time, they are the ones that need the bath treatment the most.
  • I’ve seen a lot of herds where the cows are reluctant to walk through any type of footbath. What does it do to the animals when owners use this method in a herd with lameness and the solution is very harsh on the animals’ feet? If the solution comes into contact with a sole ulcer or even a heel wart (both are exposed lesions), it causes stinging. I guarantee that this cow will remember and try to avoid that footbath for the rest of her life! Footbaths are not the ultimate treatment baths! If you know that the animal is lame, deal with the individual problem as you would with mastitis. The results and benefits will be much greater.
  • In most cases, producers quickly mix the footbath solutions before milking and place them in a return lane from the milking parlour, which is the most logical place. But what about the person handling the various products? Are they safe for him/her? Could the fumes be hazardous? As a hoof trimmer, I’ve had to smell formaldehyde throughout the day because the footbath contained it. Maybe we should wear masks when doing our trimming job to protect ourselves from the fumes.
  • In some areas, field contamination is also becoming an issue because we have to dump all the footbath solutions. Where do all those chemicals end up?

2. Lameness: Judgments Differ

Not every producer judges lameness in the same way. Some “allow” some lameness to occur, while others lose sleep if a single cow is not walking right. Therefore, I refer to the Zinpro lameness scoring chart to get everyone on the same page regarding the definition of lameness. On the other hand, you need to be honest and monitor the cows’ gait. After all, you know what hurts, you can see when they are content, and you know you’re happy when milk production is good. It’s a fact that a lame cow will not produce very well. Some speak about “acceptable levels of lameness,” but really, don’t get too complacent. The truth is that lameness increases if you ignore it.

Therefore, standardizing lameness scoring is a must for judging the success of any foot bathing method you use in your herd.

3. How to improve the use of footbaths

Footbaths remain an essential part of the total hoof care protocol. The best way to tackle the lameness challenge includes the following steps:

  • Find any lame cow in your herd and take care of her ASAP by lifting the foot. She needs your help to be able to perform at full capacity and she will reward you with better production. I’ve seen larger herd owners challenge their employees on this. The workers received a bonus in reward for every lame cow they found and treated in the hoof-trimming chute. Eventually, you’ll notice that your employees are sniffing for lameness to get their bonus, but guess what? As the herd owner, you are reaping the benefits.

This individual approach is the most important part of the hoof care protocol. It is like mastitis with milking – the sooner you solve it, the better your success rate. And, of course, just as post-dipping the teats is important for preventing mastitis, so is foot bathing for the feet to prevent lameness. However, if other aspects of management are failing, you can teat-dip as much as you want, but mastitis will still occur. The same happens with foot bathing: it’s only one aspect of the total hoof care program.

  • The next procedure involves a topical spray for use on all back feet. You ought to do the spraying once a week and it’s a great way to focus on the hooves. When using this method, you should also make sure you have a notepad or a whiteboard in the parlor. This will allow you to write down the numbers of all cows that can’t walk properly and then bring them to the hoof-trimming table for correction. As I’ve stated before, have a reward system in place to encourage your milkers to find the lame cows. It will be rewarding for them, but more so for you as the herd owner. The Veterinarian University in Calgary has done great trials with parlor spraying: view the trial overview.
  • The above steps may not address the lameness challenges in full. In such case, you should perhaps consider having a well-managed footbath as an additional preventative method. Run these protocols for a while and fine-tune them on the go. You’ll notice that the more intense hoof care approach will give you a greater ROI.
