The PRESSURE became TOO MUCH to BEAR — Transcript

Full transcript

1. 0:00I'm often asked, "What happens if a cow
2. 0:02goes lame in between your normally
3. 0:04scheduled stops?" Well, today is one of
4. 0:08those. Welcome back to Nate the Hoof
5. 0:10Guy.
6. 0:15So, most of my farms are on a
7. 0:17maintenance schedule. And what that
8. 0:18means is we will come on a set schedule,
9. 0:20in this case, every 3 months, and trim
10. 0:23all the cows that need to be trimmed to
11. 0:25keep up with that maintenance schedule.
12. 0:26But what happens if a cow goes lame in
13. 0:29the meantime? Well, that's what's
14. 0:30happened here. So, I just make an extra
15. 0:32stop and take care of those.
16. 0:40So, the problem here was pretty easy to
17. 0:42identify. And underneath, well, we're
18. 0:44going to find out exactly what caused
19. 0:46it.
20. 1:08See all these reds and purples deposited
21. 1:10in this hoof horn? That is a sure sign
22. 1:12that that suspensory mechanism inside
23. 1:14that claw has broken down and allowed
24. 1:17pedal bone pressure to affect the
25. 1:19corium.
26. 1:27So, how do we know that it was pedal
27. 1:29bone pressure that caused this and not
28. 1:31pressure from the outside because this
29. 1:32claw was overgrown? Well, if you notice
30. 1:35as I'm pairing away here, that redness
31. 1:38is disappearing. If it was due to that
32. 1:40claw being overgrown or overloaded, then
33. 1:43we would expect that that redness would
34. 1:46continue all the way down to that
35. 1:48cororeium. But it doesn't. What this is
36. 1:50showing is that that brief period of
37. 1:53time when that suspensory mechanism
38. 1:55wasn't working properly, well, that's
39. 1:57when this problem developed in the white
40. 1:58line as well as this problem that we
41. 2:01see, this redness we see in that hoof
42. 2:03horn.
43. 2:13You can see we got quite a bit of sole
44. 2:15thickness there. So, I'm going to take
45. 2:16that grinder, thin that down. I know it
46. 2:18needs to come away because we've got
47. 2:20separation there. This will just make
48. 2:21that easier to do it.
49. 2:38So, what makes that suspensory mechanism
50. 2:40break down inside that claw? And really,
51. 2:43breakdown is not quite the right word.
52. 2:45What happens is it becomes more elastic.
53. 2:48What that means is that pedal bone has
54. 2:50more freedom of movement inside that
55. 2:52claw which ultimately then affects the
56. 2:55corium because that pedal bone will move
57. 2:57down into it causing more pressure.
58. 2:59Hence, we see that redness in the claw.
59. 3:01So, what causes that? Well, there's
60. 3:03several different things that can cause
61. 3:04it. They can be from cving. When a cow
62. 3:07is getting ready to cal, there's more
63. 3:09hormones released to allow her to cal
64. 3:11more easily. that can cause that by
65. 3:14those same hormones will allow that
66. 3:16fetal bone to move. It can be some type
67. 3:18of physiological issue that she had.
68. 3:21Maybe she got sick and there the the way
69. 3:23she metabolized food was different for a
70. 3:25while. Well, that too can have those
71. 3:27same effects with some laminitis. It's
72. 3:30really hard to tell with this one, but
73. 3:32regardless, we can tell that that's what
74. 3:34happened. As I said, evidenced by the
75. 3:35fact that that redness went away as I
76. 3:38got further in there. What we're dealing
77. 3:40with here is a problem in that white
78. 3:41line, and we're going to get there soon.
79. 3:52When we have a persistent pressure
80. 3:54related issue, that's when we're going
81. 3:55to see sole ulcers, whether they be in
82. 3:57the typical soul ulcer site or in the
83. 4:00white line. When they're intermittent,
84. 4:02that redness will disappear as we have
85. 4:04here. However, if that is a persistent
86. 4:07problem, that means that redness we will
87. 4:09see all the way down to that cororeium
88. 4:11level and ultimately we're going to find
89. 4:13an ulcer at the bottom. That's obviously
90. 4:15not what we have here, but we do need a
91. 4:18block because that issue in that white
92. 4:19line, well, it's just starting to show
93. 4:21itself. Got a little bit more horn
94. 4:24around these edges to take away and then
95. 4:25you'll be able to see that
96. 4:35So, how does pressure relate to problems
97. 4:37in the white line? Well, if we have a
98. 4:38cloth that's got too much pressure from
99. 4:40fetal bone or from the outside due to
100. 4:43imbalance, then we can get a flaw or a
101. 4:45defect in that white line in that
102. 4:47junction. When that happens, that means
103. 4:50there's a crack in there which
104. 4:51ultimately will allow bacteria to get
105. 4:53in. if that persists over time. In this
106. 4:57case, the way that this could probably
107. 4:58play out, we have that change with that
108. 5:01fetal bone, right? That more movement,
109. 5:03we're having pressure problems. Because
110. 5:05of that, the claw's response is to
111. 5:07produce more hoof horn because it can
112. 5:10sense that there's a problem, more hoof
113. 5:11horn, more cushion for that claw. But
114. 5:14what that also does then is creates an
115. 5:16imbalance. When we have an imbalance,
116. 5:18then we can have a persistent issue with
117. 5:21pressure that can cause a defect in that
118. 5:22white line that ultimately over time
119. 5:25allows bacteria to get in and cause this
120. 5:28problem. So, we have to trim it out. And
121. 5:30now, we're going to get this nice rinse,
122. 5:32nice and clean. And as we usually do,
123. 5:34going to get a salicylic acid wrap on
124. 5:35that. Spray it out. But I can see
125. 5:38there's still a little bit left in
126. 5:39there. So, I need to trim that away.
127. 5:45So, what we're doing when we're
128. 5:47executing a therapeutic trim like this
129. 5:49is we're removing the problem in the
130. 5:51white line in the sole, whatever we
131. 5:53might come across, and we're using that
132. 5:55block on that other claw to reduce the
133. 5:57pressure. In this case, we've determined
134. 5:59this is a pressure related problem. The
135. 6:01block on the other claw means that cow
136. 6:02is going to put all her weight onto that
137. 6:04claw. The salicylic acid wrap, that's
138. 6:07going to take care of any bacteria that
139. 6:08might be there. And with that, she's on
140. 6:11the road to healing.
