ANIMAL WELFARE

ELISTA Education 2011



Freedom from hunger and thirst
Freedom from Hunger and Thirst

Doing little harm, but little good

No provision of Freedom

Optimal Welfare

  • Dehydrated

  • Starved

  • Malnourished

  • Good quality balanced diet appropriate to specie and life stage

  • Clean fresh water available at all times

  • Mechanism of provision

Poor quality/less appropriate food

Potentially prevent freedom from pain, injury and disease


Optimal welfare
Optimal Welfare

  • Suitable supply of balanced diet

  • Access to water

  • Mechanism of feed and water (pm)

  • Suitable to life stage/special dietary requirements (pm)


A balanced diet
A Balanced Diet

Is made up of essential “nutrients” which allow the body of an animal to function and be maintained at the level appropriate to that individuals live stage or activity level.

Nutrient=“source of nourishment…”

To Nourish=“To provide…necessary for life and growth”

A balanced diet1
A Balanced Diet…

  • Protein

  • Carbohydrates

  • Fat

  • Vitamins

  • Minerals

  • Water


Protein
Protein

  • Made up of compounds C, H, O, N and occasionally S

  • Different sequences of compounds make amino acids

    e.g Phe= Phenylalanine

    Arg= Arginine

    There are both ‘essential’ and ‘non-essential’ amino acids. Essential amino acids must be provided in the diet as not made in the body, non-essential amino acids are made through essential ones.

    Essential amino acids are required for protein synthesis (production of all cell tissue +DNA)


Protein1
Protein

  • Protein is broken down by pepsin and trypsin (within pancreatic juice) in small intestine.

The pancreas varies in size and in proportion to the rest of the animal depending on specie and gives an indication to the protein requirements.


Protein functions
ProteinFunctions

  • Protein Synthesis

  • Growth

  • Tissue maintenance and repair

  • Hormones and Enzymes

  • Components of Immune System


Protein deficiency
ProteinDeficiency

  • Reduced growth of young animals

  • Weight Loss

  • Reduced Performance/Ability or Production

  • Bad condition of coat, hooves, nails/claws

  • Impaired Immune System

  • Appetite Depravity (may eat own faeces)

    Excess protein can promote fast growth rate and possibly weight gain. Poor quality Protein can be converted to energy


Protein types
ProteinTypes

Generally categorised as HIGH biological value (HBV) or LOW biological value (LBV) protein.

Typically meat= HBV

cereals, nuts, pulses=LBV

Exceptions e.g Soya.

HBV is easier to digest.


Carbohydrates
Carbohydrates

  • Made up of compounds

    C, H, and O

  • Monosaccharides (simple sugars)

    e.g Glucose, Fructose, Galactose

  • Disaccharides

    e.g Sucrose, Maltose, Lactose

  • Polysaccharides (complex)

    e.g Starch and Cellulose

    Starch has a lot of ‘alpha’ joined glucose making it very soluble

    Cellulose has a lot of ‘beta’ joined glucose. Only rumen/caecum micro organisms can break this down


Carbohydrates1
Carbohydrates

  • Carbohydrates are first broken down by salivary amylase and then the intestines or similar.

Digestive systems of animals are adapted to break down the carbohydrates of their diet.


Carbohydrate functions
CarbohydrateFunctions

  • Provide Energy

  • System working and maintenance; brain,

    heart, nervous, digestive and immune

  • Fibre, which is also a form of carbohydrate, is essential for the elimination of waste materials and toxins from the body and helps to keep the intestines disease-free and clean.


Carbohydrate deficiency
CarbohydrateDeficiency

  • Lack of Energy

  • Potential kidney problems due to the breakdown of additional acid produced from cells functioning without glucose

  • Use of protein as energy, possible muscle wastage


Fat

  • Compounds C, H, O

  • Found as triglycerides

  • Source of the essential fatty acids;

  • Linoleic, Linolenic and Arachidonic

  • (important in endocrine and immune system)

  • Saturated fats are typically ‘solid’ (in meat and meat by products)

  • Unsaturated fats are more so ‘oils’ (in nuts, plant material)

glycerol


Fat

  • Fat is broken down by bile (produced in gall bladder) in the stomach and lipase (within pancreatic juice) in small intestine.

  • Fatty acids broken down from triclycerides in the digestive system move through the blood and lymph system to reform into triclycerides and be stored in tissue and specialised cells.

  • Fat stores can be utilised if necessary for energy.


Fat functions
FatFunctions

  • Carry electrons (part of atoms)

  • Component of cell membranes (as lipids)

  • Store for some vitamins

  • Energy

  • Insulation

  • Normal functioning of body systems (esp. Immune and Endocrine)


Fat deficiency
FatDeficiency

  • Poor coat

  • Flaky skin

  • Hair Loss

  • Impaired Reproductive Efficiency


Vitamins

Vitamin b s water soluble
Vitamin B’s (Water Soluble)

  • Types: Vitamin B complex includes:

    Thiamine (B1), Riboflavin (B2), Folic Acid (B9)alsoB3,5,6,7,12

  • Source:Most B vitamins are synthesises in the gut (B12 from Cobalt), all but B12 are also found in most unprocessed food

  • Function:Involved in metabolism of protein, carbohydrates, fat and haemoglobin. Vit B12 used to convert the acid produced by intestinal microbes of ruminants to glucose.

  • Deficiency:Many deficiencies conditions in humans, animals less affected, although deficiency in B12 can affect ruminants

  • Excess:Toxicity is rare

  • Excretion (urine and sweat)

  • Hydrolysis (splitting of water for H protons)



How do we know the food we eat is appropriate for us
How do we know the food we eat is appropriate for us?

  • Make ourselves knowledgeable

  • Pay attention to experts

  • Trial and error (see what works)

  • Personal Preference (Palatability)…

    We should aim to

    do the

    same for our

    animals!


Making ourselves knowledgeable
Making ourselves knowledgeable…

Researching such as…

  • Natural feeding Substrates

  • Natural feeding methods

  • Specie / Breed lifestyle

  • Breed predispositions

  • Individual animal


Pay attention to the experts
Pay attention to the experts…

Nutritional science has made huge advancements in recent years. Science can guide us on:

  • What nutrients animals need

  • What quantity those nutrients are required in

  • What level of feeding should be provided depending on performance

  • How much of the food provided animals are digesting

  • What animals favourite tastes and flavours are….

    …and so on!

    As with many areas of science though, there are discrepancies and difference of opinion.
