Para los alimentos en harina es importante el tamaño de particula, como calcularlo?

Buena información sobre el calostro

Buenas tardes, puedes empezar con lo básico.
Filtración
Calidad del agua.
Estanque limpio.Pero es importante conocer las propiedades químicas de estos.
Saludos

particle size depend on the age of birds to know the expected particle size to provide for easy digestion and FCR
-
combination of corn,rice bran,SBM which have its own crude protein individually and when mixed together in right proportion gives total expected crude protein

Good

Great, thanks

1. Calcium (Ca):
Bones:
Main structural component of bones and teeth (as hydroxyapatite).
Deficiency → rickets (young animals), osteoporosis (adults), weak legs in poultry.
Eggs:
Essential for eggshell formation (95% of shell is calcium carbonate).
Deficiency → thin-shelled or shell-less eggs, increased egg breakage, reduced hatchability.
Health:
Needed for nerve transmission, muscle contraction, and blood clotting.
Imbalance with phosphorus can cause poor bone mineralization.
2. Phosphorus (P):
Bones:
Works hand-in-hand with calcium in bone mineralization (Ca:P ratio is critical, usually around 2:1 for poultry and livestock).
Deficiency → poor skeletal development, rickets, stiff joints, reduced growth.
Eggs:
Important for egg formation (yolk contains phosphorus-rich compounds like phospholipids).
Deficiency → small eggs, poor hatchability, reduced production.
Health:
Key in energy metabolism (ATP = adenosine triphosphate).
Also important for DNA, cell membranes (phospholipids), and acid–base balance.
3. Selenium (Se):
Bones:
Not a structural component of bone like Ca and P, but supports bone and muscle health by reducing oxidative damage.
Deficiency → muscular degeneration (white muscle disease in calves, lambs, and poultry).
Eggs:
Incorporated into eggs, improving chick viability.
Acts as an antioxidant, protecting yolk lipids and embryo from oxidative stress.
Deficiency → poor hatchability, embryonic mortality.
Health:
Integral part of glutathione peroxidase, an enzyme that protects cells from oxidative damage.
Deficiency → reduced immunity, reproductive problems, retained placenta in cattle, sudden death in poultry due to exudative diathesis.
Toxicity (narrow margin): causes hair loss, hoof damage, and reduced performance.

1. Disease Introduction through People and Equipment:
Frequent movement of farm workers, veterinarians, feed trucks, and egg collection vehicles increases the risk.
Shared equipment between breeder farms and other poultry units spreads pathogens like NDV, IBV, AI, and Salmonella.
2. Vertical Transmission Risks:
Breeders can pass pathogens directly to chicks through hatching eggs (e.g., Mycoplasma, Salmonella pullorum, Salmonella enteritidis).
Even a low-level infection in breeders can have a huge impact downstream.
3. High Stock Value and Concentration:
Breeder birds are genetically valuable and housed in concentrated numbers.
A single outbreak leads to massive economic losses, especially with diseases like Avian Influenza (AI).
4. Rodents, Wild Birds, and Insects:
Rodents spread Salmonella, Pasteurella, and E. coli.
Wild birds carry AI and Newcastle Disease.
Flies and beetles spread IBD, Marek’s, and bacteria within and between houses.
5. Egg Handling and Hatchery Link:
Contamination during egg collection, storage, and transport introduces pathogens to hatcheries.
Poor sanitation at the hatchery spreads infection to thousands of chicks.
6. Water and Feed Contamination:
Breeder birds require large amounts of feed and water. If either is contaminated with pathogens, flock-wide infection occurs rapidly.
7. All-in/All-out Difficulties:
Unlike broilers, breeders stay for a long cycle (40–60 weeks).
This makes it harder to completely clean and disinfect houses frequently, leading to gradual pathogen build-up.
8. Vaccination and Biosecurity Gaps:
Vaccination is essential but not always foolproof (improper handling, poor take, or new strains).
Over-reliance on vaccines may lead to neglect of strict biosecurity.
9. Human Factor / Compliance Issues:
Workers may bypass shower-in/shower-out rules or footbath use.
Contract farms may not strictly follow the integrator’s biosecurity protocols.
10. Regional and Environmental Challenges:
In many regions (like parts of Africa and Asia), backyard poultry farms nearby serve as reservoirs of NDV, AI, and other pathogens.
Tropical climates favor rapid spread of parasites, bacteria, and fungi.
