Animal Management Flashcards
Herbivore anatomy
Large, wide flat back teeth (ruminants, no front teeth)
How does the anatomy change based on diet (example of calf to cow)
Large abomasum for liquid diet changes to large rumen for digesting plant matter
Forage
Any plant matter
What are the 4 types of pasture?
Rough grazing, permanent pasture, ley (grass sewn for forage), and rotational grass
Maize and fodder production
- Leaves dry, whole crop chopped and grain cracked
- Common for dairy due to high DM and starch content
How does the composition of grass change?
- Early grass, high protein
- Late grass, low protein, more fibrous
Silage (forage conservation)
- Pickled and fermented
- Grass is cut and oxygen is squeezed out which allows bacteria to break down sugars producing lactic acid and preserves hay
- Exposure ot oxygen makes it go bad
Hay (forage conservation)
- Dried, nutritive losses
- Easy to transport, less contamination, small volumes
- suspect to mould and oxidation
Haylage (forage conservation)
- hay x silage
- higher water content, prone to spoilage
- fed to horses
Straw (forage conservation)
- Dried stem of wheat, barely and oats.
- Given to ruminants on high concentrate diets
Concentrates
- High in protein and energy
- Need to be fed with roughage in ruminants to avoid acidosis.
Straights (type of concentrate)
Individual grain
Mixes (type of concentrate)
Variety of grains as museli or pellets
Cow
Adult female
Heifer
Female who has had 1 or less calves
Bull
Male
Steer/ Bullock
Castrated male
Bull Calf
Male calf
Calf
Young bovine
Dairy cow common management types (3)
- Indoor year round (zero-grazing)
- Outdoors year round
- Mixed
Beef cow management types (2)
- Intensive- housed and fed concentrates (suitable for later maturing breeds who grow quickly)
- Extensive- Beef from grass (Early maturing breeds who need to be grown longer)
Calf nutritional requirements
- Colostrum
- Water (from day 1)
- Milk
- Concentrates
- Forage
Vet roles in bovine industry
Abattoir work, government, research, investigation officers
Dairy cows insemination options
- Dairy x Dairy (Bull calfs raised as meat)
- Dairy x Beef (worth more in beef industry)
Suckler Herds
Cows kept purely for beef. (sold as calves, kept on farm until slaughter, sold as stores)
Store cattle
Older cows being housed a second winter to fatten on grass and sold under 30 months.
Holstein- Friesian
Dairy, black and white, high milk, 680-770kg
Ayrshire
Dairy, dark red and white, smaller and hardy, housed mostly outdoors, 450-600kg
Jersey
Dairy, milk rich in butterfat, 400-450kg
Guernsey
Dairy, red-brown and white patches, high butterfat content, 450-500kg
Hereford
Native (slow growing), beef, red with white face and chest, fast growing with food feed conversion
Aberdeen Angus
Native (slow growing), beef, black, good calving ease and good milk for young, good feed conversion and naturally polled (no horns)
Belgium Blue
Beef, White, blue roan or black, double muscling, struggle to give birth, high feed conversion and good temperament
Limousin
Beef, Golden Red, meat has low proportion of bone and fat, high feed conversion
Simmental
Beef, Light brown and white patches, Highly efficient, minimal waste fat, docile and good mothering ability
Difference between horse and pony
- Determined by height (foot to withers. Ponies are less than 14.2 hands)
- 1 hand = 4 inches
Heavy breeds/ cold bloods and function (UK native - 5)
- Strong, easy going
- Designed to pull farm machinery
- Inclu. Shire, Clydesdale, Suffolk, Cleaveland Bay, Irish Draught
UK native ponies (Children’s riding ponies) (5)
Shetland, Dartmoor, Exmoor, New Forest, Welsh
UK native ponies (Tough, evolved to live in wild places) (3)
Connemara, Dales, Highland
Hotbloods
- Speedy, less calm
(ex. Thoroughbred, Standardbred, Quarter Horse, Arab)
Breeds commonly used for competition in UK
- Thoroughbred (racing)
- Warmblood (thoroughbred x cold blood)
- Irish Sport Horse (Thoroughbred x Irish Draft)
Dressage
- Executing complex movements based on control and steering.
- Exclusively warmbloods
- “Horse Dancing”
Showjumping
- Fastest time to complete jumps without faults (knocking poles, stoping or missing jump)
- Exclusively warmbloods
Eventing
- Triathalon (dressage, cross country, show jumping)
- Usually Thoroughbred crosses
Racing (and types (2))
- Flat racing: shorter distance, no jumps, horses 2-3 years
- National Hunt racing: longer over fences, horses 4-5 years
Polo
- 4 riders per team, hit balls through goal
- Thoroughbred or thoroughbred cross
Endurance
- Long distance races, have to pass vet checkpoints
- Arab
Driving
- Teams of 1,2,4 horses pull carraige through obstacles
Showing
Dog show
Vaulting
Gymnastics on horseback
- Quite strenuous, constant, steady pace.
Western riding
Quarter horses, mostly reigning in the UK
Horse management types
Stabled (stereotypies, respiratory disease), at grass (injuries, skin disease) or combination
Colic
Abdominal pain due to sudden change in management or feeding
Gastric ulceration
Due to periods of feed restriction and commonly found in high-intensity exersized horses
Myopathies
Overexertion, muscle breakdown after exercise
Cow gestation period
9 months
Calving interval
Calf-calf (approx 385 days
When does oestrus happen in calves
Based on weight
1st service timing
- First breeding at 14-15 months, 55-60% of adult body weight
How is cow weight measured?
Heart girth
Challenges of entering the milk herd
- Spending lots of time standing around, poor access to feed, stress
How soon is a cow bred again after giving birth?
60-85 days
Early lactation dates
0-100 days, peak at 5-6 wks, up to 50L a day
Mid-late lactation (100-305) and how dealing with high and low yielders
High yielders given high energy diet and vise versa (prevent obesity and trouble calving in low yielders
Dry period and process of drying off
- around 60 days
- Early dry period (far-off cows) and Late dry period (transition cows)
- Use internal teat sealant and intra-mammary antibiotics, only when needed.
Ewe
Female sheep
Ram (a.ka. Tup)
Male sheep
Lamb
Young sheep
Gimmer/ Hogget/ Shearling/ Two-tooth and their approximate age
Young sheep with no more than 2 permanent incisors (usually between 12-19 months)
Wether
Male castrated sheep
Teaser
- Vasectomised sheep that is no longer fertile but maintains desire to mate
- Used to bring ewes into oestrus
Finished lamb
Fattened lamb ready for slaughter
Draft ewes
Older hills used transported to uplands to cross breed
Lambing timing (The sheep year)
- Usually in the spring (w/ grass growth and warm weather)
- Sometimes in December
Spring/ Early summer (The sheep year)
- Ewes and lambs grazing (lambs gaining approx 300 grams a day)
- Ewes may need supplements w/ concentrates and lambs with creep feed
Summer (The sheep year)
- Lambs weaned at 8wks
- Fattened and sold a 5-8 months, approx 40kg
- Shorn for fly control
Autumn (The sheep year)
- Tupping/ mating period 5 months before
- Rams with ewes for 6-8 weeks (2 oestrus cycles)
- 1:25 - 1:100
How long is the sheep oestrus cycle?
5 months
Pros and cons of stratified sheep breeding system
- Able to use all types of land
- Breeds matched to different land
- May require movement between pastures
Hills (combinations, elevation)
- Hill ewes x Hill rams
- 500m +
Upland (combinations, elevation)
- Draft ewes/ Longwool ewes x Longwool rams
- (Draft ewes x longwool rams = cross-bred ewes)
- 300-500m
Lowland (combinations, elevation)
- Cross-bred ewes/ terminal sire ewes x terminal sire rams
- Less than 300m
Hills sheep characteristics
- Hardy, thick coats
- Good mothers
- Able to cope with harsh conditions and walk long distances
Hills output
- Sold as stores
- Draft ewes sold to upland
Upland sheep characteristics
- More prolific than hills
- Good mothering ability
Upland output
- Mule lambs (draft ewes x longwool rams)
Lowland sheep characteristics
- Fast-growing, heavy frame
- Prolific
Lowland output
- Cross-bred lambs (Mule ewe x terminal sire)
- Fattened store lambs from uplands and hills
Sustainable sheep breeding examples (3)
- Lambs that finish quicker on grass
- Lighter ewes (less food) with same lambing output
- Ewes w/ less lambing intervention
Sheep sources of income
- Meat (increasing)
- Wool (decreasing)
