What’s chicken Meal vs chicken byproduct meal
Chicken meal: rendered product from a combination of clean flesh and skin with and without accompanying bone, derived from whole carcasses or chicken thereof
Chicken byproduct meal: ground, rendered, clean parts of the carcass of slaughtered chicken, such as necks, feet, undeveloped eggs and intestines.
Byproducts include lungs, liver, spleen, kidneys

-Novel: potato protein, rice protein, pea protein
Protein in economical vs. humanization brands
Economical brands: higher inclusion of plant based (SBM) balanced with a lower quality animal protein (meat and bone meal)
Humanization brands: minimize or fully exclude plant based proteins (based on owner bias)

How to prevent ammonium phosphate crystals in urine?
These are commonly called struvite crystals
Found in young dogs and cats.
Diets may be avoided and Mg concentrations kept low to prevent struvite formation
How to prevent calcium oxalate crystals in urine?
Commonly called “oxalate crystals”

What is the difference between “formulated” and “fed” diets?
Formulated- nutritionist simply formulates to the requirements set by AAFCO
Fed- nutrionist formulates to the AAFCO requirements then conducts a digestibility test and growth or maintenance study to verify efficacy.

What are the advantages and disadvantages of high fat feeds/diets for horses?
Advantages:
-highly digestible energy source
-no risk of colic or laminitis
-improved performance (aerobic)
Disadvantages:
-reduced performance (anaerobic)
- reduced fiber utilization if fed at high levels

-decreased bone mineral density
-angular limb deformities, osteochondrosis
What is colic?
Intestinal distention. Stretching of mesentric support. Inflammation of intestines.
Severe abdominal pain.
Causes and symptoms of colic.
Causes: intestinal spasm (rapid dietary change or endotoxins)
Impaction (inadequate and/or poor quality forage, dehydration, ingestion of sand or soil, internal parasites)
Symptoms: loss of appetite, grinding teeth, stretching posture, looking and or kicking at abdomen, uneasiness and rolling, sweating, increased HR >60bpm, increased RR
How to prevent colic?
-consume at least 1% BW in forage
- don’t feed more than 0.75% bw concentrate at a single feeding
-abundant clean water
-regular exercise
-don’t feed moldy or dust feedstuffs
-don’t feed on ground
-avoid sandy own surfaces
-deworming program
What is laminitis (founder)?
Inflammation of laminae. Rotation or sinking of coffin bone
Chronic laminitis leads to founders
Sensitive and insensitive laminae of the hoof wall separate ( bond between them falls). The attachment of the coffin bone to the hoof breaks down.
Symptoms of laminitis?
Lameness
Abnormal hoof growth
Irregular gait
Causes of founder?
Overconsumption of grain or lush pasture
Retained placenta
Concussion
Excessive weight bearing
Prevention of founder?
Don’t over feed grain
Use fats to supply extra energy rather than carbs
Gradually introduce grain and mush forages into diet
Be cautious when pasturing horses during periods of rapid forage growth
What is cantharidin toxicosis?
“Blister beetle poisoning”
Beetles or beetle parts ingested in hay
What are symptoms of cantharidin toxicosis?
Blistering of oral mucosal membranes
Profuse sweating
Muzzle splashing
Abdominal pain
Frequent urination
How to prevent cantharidin toxicosis?
Don’t feed legumes
Avoid harvesting field borders
Don’t use crimpers
Harvest before flowering
Spray with short acting insecticide like sevin
Buy alfalfa before may or after September
What is heaves?
“Inflammatory airway disease”
Similar to asthma in humans
Irritants in trachea and lungs cause hyper secretion of mucous and thickening of airways.
Lung alveoli become scarred and brittle, increasing chance of rupture
What causes heaves?
Allergic reactions to fungal spores in feed, bedding, environment.
Dusty or moldy hay
Dust environment
Symptoms of heaves?
SOB
Increases RR
chronic cough
Heave line on flank d/t exertion of abdominal muscles
Nasal discharge
How to prevent heaves?
Don’t feed hay that is moldy or dusty
Avoid finely ground feedstuffs
Pasture horses if possible
Consider using high moisture forages like haylage
Keep pen and stable surfaces clean and dust free
Use dust free bedding
What is polysaccharide storage myopathy (PSSM)?
Genetic condition that leads to “tying up”
Muscles contain abnormally large amounts of abnormally branches glycogen.
Muscle cell destruction results in release of myoglobin which is excreted in urine.
What is polysaccharide storage myopathy (PSSM)?
Genetic condition that leads to “tying up”
Muscles contain abnormally large amounts of abnormally branches glycogen.
Muscle cell destruction results in release of myoglobin which is excreted in urine.
What causes PSSM?
Feeding performance horses high starch diets during intermittent periods of inactivity
Symptoms of PSSM?
Stiff gait
Reluctance to move
Profuse sweating
Accelerated HR
increased RR
wine colored urine
Often follows rest period
How to prevent PSSM?
-provide performance horses with light exercise on days off
-allow performance horses to rest on pasture whenever prudent
-reduce or eliminate dietary starch (use fat for energy)
-affected horses should be allowed to rest and provide plenty of water (protects kidneys from damage as myoglobin is excreted)
What is ionosphere toxicosis?
When a horse consumes ionospheres which are in cattle diets. Very toxic to horses (1mg/kg bw is lethal)
Sx: muscle tetany, posterior weakness, profuse sweating
What are the advantages and disadvantages of phase feeding of swine?
