Clinical Case – evolution and results

Filed under: Hoof Care — Almudena @ 14:29 pm

Hello! Here we are again, to comment news about the cow from previous post.

In the preview post we did not tell how we have treated this cow. Well, she already came with an XL block, which was ok and we left. But, after trimming and cleaning, we put a shock-absorbing bandage. With topical antibiotics, special cotton (repeals humidity), jute and finally cohesive bandage. We decide with farmer to do weekly reviewing.

We have done 4 reviews, last one after 15 days from previeus review. In all of them we have change bandage, always using the same matherials.

Cow has been two weeks in deep strw bed, in nursery. Then, because lesion development was really good, she has been moved to cubicle barns. This is the main reason why we kept the same bandage tupe in all reviews, because in cubicle barns is easier to hurt a weak claw.

You can see the evolution in photos below:

First Review: lesion has 2,5cm diameter. Necrosis is seems healed and there is only ulceration. There is no contact with third phalanx from outside.

Weight bearing is better than before, although right hind limb (affected limb) is always ahead from left hind limb. Locomotion Score 3.

Second review: 1 week later. ulceration has 1,5 cm diameter. weight bearing is going better. LS 2-3

Third review:

We found that the block is not useful any more, cow is using diseased heel while walking and block is worn-out too (see photo below). This fact usually appears in toe lesions, it is important to place blocks as caudal as possible, to help in weight bearing.

Lesion has 1 cm diameter. We put a new XL block andnew bandage.

We decide that healing is going well and next review will be in 15 days.

Fourth review: lesion is healed. Block remains at sound claw because wall and sole new horn in affected claw is not hard enough and could be damaged.

Weight bearing is normal. LS 1.

Below you will find a table which shows lactacion of this cow (red line). You can see a huge depression in dairy production on 27th july, after removing third phalanx portion. Then, she started to recover and nowadays produces around 50L per day.

Clinical case

Filed under: Hoof Care — Almudena @ 13:58 pm

A few days ago we got a clinical case we think it could be very interesting. It is a cow, Holstein Freisian, which has nowadays a chronic lesion in the external claw of the right hind limb since March 2014.

The cow is in 3rd lactation, less than 100 days in milk. She lives in a farm which we visit weekly. So she has been re-checked every two months from March 2014 until April 2015. Then, during April, we have re-checked her weekly. But after April she didn’t get in the crush any more…until a few days ago, when we met her again. And this is what we found (she came with the block already):

She has a toe necrosis, probably it has developed from a toe ulcer that never healed. These are the results of our therapeutical trimming (with an extirpated fragment of 3rd phalanx included):

What do you think about this case and our work? would you have trimmed more? or less?

Apart from trimming, how would you treated it?

Which is your prognosis? will it heal?

Give us your opinion and in a few days we will share some more information about how is she going!

About these hooves

Filed under: Hoof Care — Almudena @ 19:22 pm

Hello everybody!

We posted last week some curious photos…

And we have promised we will explain why they look like this:

These animals are beef cattle which mainly live in pastures. It seems they didn’t found many grass at the beginning of spring and they have eaten oak sprouts and acorns.

Oak sprouts and acorn have a huge amount of tannins, which are toxic substances for ruminants. Actually, not all kinds of tannins are toxic and some are used in animal feeding, but, most tannins in scrouts and acorns from Quercus genre plants are nephrotoxic. In result, these cows had a toxic stress with different symptoms related with renal disorders; luckily farmer and vet could resolve it and, after some weeks, farmer noticed these lesions and called us. They are horizontal fissures.

A horizontal fissure is a groove in the claw wall that runs parallel to coronary band. It is a temporary claw formation and growth disruption caused by stress (physiological, metabolic, toxic or diseased related). It may cause double soles (as it did in these cows).

Recommended treatment is a careful therapeutic trimming, to eliminate double soles. And next spring concern about what do cattle in pastures are eating ;)

What do you think?

Filed under: Hoof Care — Almudena @ 13:17 pm

We have visited a beef cattle farm (extensive production) to make preventive hoof trimming, cows are a typical breed of this area of Spain (Pirenaica, similar to Blonde d’Aquitaine)….and we found this.

What do you think abou it? any idea about possible sources?
We have already found it out…we will tell you next week!

Have a nice weekend!

Clinical Case

Filed under: Hoof Care — Almudena @ 12:27 pm

This week, during our programmed visit to a barn we had a clinical case which could perfectly appear in a book.

It was a Sole Ulcer in the front left foot, at the medial claw. But there was an herniation of the corium.

We treated it with an orthopedic shoe, Easy Bloc 95 from Demotec, on the lateral claw. Then, we removed the herniation.

Photo 1. Affected claw before treatment.  Photo 2. Affectad claw after putting the bloc.

Furthermore, she had another herniation at the left hind foot, on the lateral claw. Which was also removed (the herniation).

In this cases there is some discussion between professionals, not everybody would have removed the herniation…what would you have done? do you think is better or worse to remove this part of the corium?

Photo 3. Left hind claw with also a sole ulcer and herniation of the corium at the lateral claw

The cursed sentence: “the cow is lame”

Filed under: Events,Hoof Care — Almudena @ 20:39 pm

In the last ANEMBE Conference (Bovine Medicine Specialists Spanish National Association) the topic “lameness” wasn’t really important compared with other topics. That was exactly discussed in one of the lectures: the less attention that the scientific society pays to the improvement in lameness treatments.

The lecturer was Jon Huxley, professor in Animal Health and Production at the University of Nottingham (United Kingdom).
He presented three researches:

The first research was an analysis about podal pathologies in cattle literature (in particular, white line disease and sole ulcer) and qualified researches about possible treatments.

The result, the number of research articles which really talk about this topic is a little bit poor…in conclusion; the basis in bovine lameness treatments comes from a few books and other sources like experts’ criteria and clinic experiences. This is not wrong and, actually, is very useful for all of us…but it’s also sad because the few interest that the scientific society has in this area, lameness, which is one of the most important things in farms all over the world.

The second research was a controlled and randomized clinical trial in five farms from the UK. It consisted in scoring loading in 1100 cows and, those which where lame, were included in the trial. These animals were functionally trimmed and after that, they were divided in four groups and each group received a different treatment (for white line disease and sole ulcer).

The recovering differences between treatments were marked. Surprisingly, the author admitted that the methodology of the trial has been complicated and applying it has required many time, although the trial was made in a reduced area…this can give us some clues about why there are not many research in hoof trimming and cattle podal pathologies.

The last research, and which I found more interesting, was an opinion poll from 84 farmers from the UK. The intention was to find out how they treat lameness and when:

- In more than two thirds of the farms, the lameness treatments were made by a worker.

- Three quarters answered that treatments are made in a 48h period…but it depends on the work amount in the farm and the severity of the lameness.

- They expressed the relation between the uses of an inappropriate material and wrong manage systems with a wrong or well done trimming. They admitted that having good material and managing well cattle is more motivating, the recovery is usually better and quicker.

- And then comes the best one: when farmers were asked to estimate how many lame animals they have, they counted only the most severe lame animals.

The lecturer concluded that farmers don’t identify “well” or they “don’t know” how to identify lameness in cattle. The thing is that, probably, they don’t score lameness like specialists and scientists do, but it doesn’t mean that they don’t know how to do it.

Surprisingly, farmers have avoid to use the word “lame” during the poll, especially in those animals which we would score as lame and would want to treat. On the other hand, the most severe cases were scored as “lame” and had priority for treatment in the farms.

We should think about this, and take care about our daily work and communication with producers. We should make them understand that lightly lame cattle should be detected and treated as soon as possible, consequently, economic losses would be less. A good option would be explain the situations comparing lameness with mastitis cases in dairy cows. Most of the producers treat mastitis as soon as possible and really care about this pathology, because they know well the consequences if cows aren’t treated.

In Anka Hoof Care we would like to know how the profile from your customers is, if they become aware of lameness, if they like preventive trimming or call you just for treating the most severe clinical cases. And if you are a producer, how do you deal with lameness in your farm.

Feet problems in Mexico

Filed under: Hoof Care — admin @ 8:30 am

This is a case sent by Mario Rodríguez DVM . He describes a problem found in some Dairy farms in Jalisco México.
Cows that had no previous feet pathology,they start with a coronary band swelling and from one day to other they lose the hole claw at the third phalanx level as you can see at the pictures
Most of the cases are second lactación cows with different days in milk. Mario suspects in fluor poisoning, Any sugestion?

Foot rot?

Filed under: Hoof Care — admin @ 10:58 am

This is an odd case involving a cow:

First, the cow had Fool (Foot rot), was treated and healed. But few days after that the leg got inflammed with huge pain.

As you may see in the pics, when Miguel put a needle a semitransparent (nearly yellow) liquid appears with pressure without detectable smell. After that, swelling and pain decrease.

Question: Could it be an antibiotic accumulation? Or maybe a leak of synovial fluid?
