Q

What is hay belly?

A

Undigested roughage accumulates

Rumen overfill and dilates

Eructation contractions too weak to expel gas

Recurrent bloat.

Poor growth skeleton rough coat … hay belly
The function flora is to cellulose digestion
Need adequate protein starch cellulose

Empty rumen

24
Q

Rumen putrefaction

A
Blackish green 
Foul putrid odor 
Ph -7_8
Poor microflora no.s a
And motility 
Frothy
25
Tx farmer alkalosis
Sugar brown Yeast Vinegar
26
3 main sources of wire
Fence Feed Lying around
27
Pica
Aphosphorosis
28
Trp
History of getting sick -antibiotics -relapsing usually after partus rumen migrates to heart-chf Ingesta leak Peritonitis-a Adhesions
29
Garbage disease
Extensive low quality grazing | Aphodphorioften palpate hard mass in rumen
30
Bloat
Excessive accumulation of gas in the rumen Due to failure if the eructation mechanism to remove gas NOT DUE TO EXCESSIVE GAS
31
Free gas bloat .
If really battling relive bloat pressure | Passing a stomach tube can take time and cab compromise airway patency
32
Bloat plant factors ?
Increased incidence when grazing lucerne or clover pastures ...
33
Plant factors if bloat
Saponins,pectins, henicellulose form a nonnuclear layer around gas bubbles. Growth stage-lush rapid growth early bud stage Influences by genetic factors . Increased incidence in holsteins . Especially in feedlots .
34
Defaunation agents
Decrease incidence and severity of frothy bloat.
35
Frothy bloat cs
``` Colic/kick get up and down Hind leg treading Projectile vomiting Attempt to urinate and defecate Increased heart rate Vena cava occluded Increased pressure in diaphragm Decreased lung capacity Dyspnoea ``` Hypoxia suffocation The forth blocks cardiac

37
Quick farmer solution for bloat whilst waiting for vet
In slope walk with chain in mouth to encourage saliva flow
38
Free gas bloat?
``` Oesophageal obstruction Extreme distension Exaggerated swallowing Drooling Colic Rapid respiration Increased HR Cyanosis Use a stomach tube ```
39
Feedlot bloat
90 percent are frothy bloats Production of insoluble slime by bacterial species Finely ground feed Ruminate less... less saliva and lower ph Happends with increased levels of grain ,less roughage time for bugs that produces slime to proliferate
40
Fact
Blat can be one of 3 things Oesophageal obstruction Cardiac obstruction Rumen wall
41
Rumen acidosis is characterised by?
``` Anorexia Depression Dehydration Diarrhoea Metabolic acidosis ```
42
Critical periods for acidosis?
Weather changes. Heat cold winds
43
Causes of acidosis
``` Readily fermentable carbohydrates. Barley Wheat maize corn Oats Sorghum ```
44
Clinical signs of acidosis
Rumen contents and H20 bery watery Light yellow brown smells sour . Ph 4/5
45
Fact
Carbohydrates are too much and readily fermentable this causes less saliva and then a drop in ph . And in increase in the amount if Volatile fatty acids . Lactic acid increases Streptococcus Lactate utilisers convert lactate into probiotic acid. Rumen slows down stasis.
46
Acidosis facts
Protozoa die increase in number of endotoxins can case endotoxaemia ``` Gram negative bacteria die Ph less than 5.5 Decreased thiamine production increase lactic acid Increased fermentation Lacate utilisers are inhibited decreased vitamins b1. All this then causes PEM ``` ``` All this will draw H20 into rumen osmotic pull Slushy watery and distended rumen Dehydration happens Then shock Then DEATH ```
47
Acidosis further complications and facts
``` Incrwasing metabolic acidosis Rumen stasis Bloating Less vit b 1- PEN Bacteria die leading to release if endotoxins-endotoxaemia Endotoxaemia causes laminitis Rumentitis -pain ``` Mucor mycosis causal vena cava syndrome Hypertonic rumen - dehydration anuria nephrosis- death
