THYRO PROTEIN

SPECIFICATION:
1.Appearance: brownish yellow powder
2.Odour: no smell or a little caramel odour
3.Content: ≥12.0%
4.Total protein :≥70.0%
5.Moisture :≥10.0%(drying at 105)

MECHANISM FOR ACTION:
Thyroprotein is the precursor of thyroid, it has thyroidal physiological function, so it is named as like thyroid. When it enters into animal's body, it can play following roles:
1.Join the metabolism of substances in the animal's body, e g. Reinforce the metabolism of fatty, sugar and protein.
2.Improve the permeability of blood capillary and make the excretive of kidney stronger. 
3.Promote growth of baby livestock.

BENEFITS:
1. For chicken and duck:
2. Promote growth, better the quality of meat, bright the feather, raise the rate of oviposition and improve the thickness of eggshell.
3. For cattle:
4. Increases the milking quantity of dairy cow and the content of butterfat. 
5. Promotes growth of beef cattle.
6. For milking sow and piglet:
7. Increases the milk quantity of sow, raise the body weight of weaner and weaner reduce the death rate.
8. For live hog:
9. Improves the utilization ratio of the feed, promotes growth, increases the lean and improves the quality of slaughtered hogs.


MODERN RESEARCH:
Significantly increased (P <.05) growth rate was obtained by the feeding of thyroprotein at levels of 0.0088 percent, 0.0132 percent, and 0.0176 per cent of the ration of growing, fattening swine. 
Less feed per unit of gain was required by all animals receiving thyro protein in their ration. 
When compared on the same age basis, hogs receiving thyroprotein had a higher percentage of fat and lower percentages of moisture, protein, and mineral matter than animals receiving no thyroprotein. 

SUGGESTED LEVEL OF ADMINISTRATION 
Milking sow: 100--200ppm
Piglet or porket: 50--100ppm
Live hog: 50--100ppm
Chicken: 100--200ppm
Duck: 100--200PPM
Dairy cow: 7mg/kg b.w/d(in the winter); 5mg/kg b.w/d(in the summer) 

PRECAUTIONS
1.Thyroprotein should be added into the feed three days before pregnant sow delivers and it should not be stopped until the ablactation. If it is stopped suddenly during lactation period, the milking quantity of sow will be reduced rapidly. 
2.In order to prevent the body weight to be lightened excessive thyroprotein should not be used in the feed. The sow feed during lactation period should contain 15% protein, high energy(TDN70--75%)and high unit vitamin.
