Starch is an important source of energy for cows, but its digestibility can vary depending on several factors, including corn variety, grain maturity, particle size, and fermentation time.
The video shows several tips for improving starch digestibility in corn silage:
Factors Influencing Starch Digestibility
Corn variety: Choose a variety with an optimal ratio of glassy and floury grains. Vitreous grains are more digestible than floury grains.
Grain maturity: Harvest maize at the right stage of maturity. Corn that is too mature will have less digestible starch.
Particle size: Grind corn into optimally sized particles. Particles that are too fine or too large can reduce digestibility.
Fermentation time: Allow the silage to ferment for an adequate period of time. Fermentation that is too short or too long can reduce digestibility.
Techniques to improve digestibility
Grinding or rolling grains: Grinding or rolling corn kernels before ensiling them increases the attack surface of the enzymes and improves digestibility.
Use of enzymes: Adding exogenous enzymes to silage can help break down starch and improve its digestibility.
Ration adjustment: Adjust the cow's diet according to the digestibility of corn silage.
Conclusion
By following these tips, it is possible to improve the starch digestibility of corn silage and increase cow milk production.
Important things to remember
The digestibility of starch in corn silage is important for cow milk production.
Several factors influence starch digestibility, including corn variety, grain maturity, particle size, and fermentation time.
There are several techniques to improve the digestibility of starch, such as crushing or rolling grains, using enzymes, and adjusting the food intake.
