TODAY’S MEAT-TYPE BIRDS GROW VERY RAPIDLY BODY WEIGHT BROODING 1000 HOURS AGE 42 DAYS MOST CRITICAL PERIOD
Gut development ….FACT…. WHEN FEED INTAKE DECLINES GUT DEVELOPMENT DECLINES
IMPORTANT NUTRITIONAL CONCEPT NUTRITION IS NOT FIXED NUTRITION IS FIXED
NUTRITIONALLY SPEAKING WHAT ARE THE ONLY SIX THINGS CHICKENS NEED ?
CARBOHYDRATE LIPID PROTEIN VITAMINS MINERALS WATER SIX MAJOR NUTRIENTS
VERY IMPORTANT CONCEPT OF NUTRITION TO REMEMBER …..ENERGY IS NOT A NUTRIENT….. IT IS A “PROPERTY” OF THREE NUTRIENTS CARBOHYDRATE LIPID PROTEIN
VERY IMPORTANT CONCEPT OF POULTRY NUTRITION TO REMEMBER MOST POULTRY EAT THE AMOUNT OF FEED THEY NEED IN ORDER TO MEET AN ENERGY REQUIREMENT
IMPORTANT FACT TO REMEMBER …TODAY… FEED COSTS REPRESENT APPROXIMATELY 75% OF THE TOTAL COST OF PRODUCING MEAT AND EGGS

Newcastle diseases Virus (ND/Ranikhet )
Newcastle disease virus (NDV) • A type strain for avian paramyxoviruses. Members of this family have a single stranded, linear, RNA, with an elliptical symmetry. The total genome is roughly 16,000 nucleotides. Replication of the virus takes place in the cytoplasm of the host cell. • This family also includes important viruses such as mumps, human parainfluenza, sendai, simian virus-5 and recently emerged nipah and hendra viruses. • NDV particle
Newcastle Disease (ND) • ND is caused by Newcastle disease virus • A disease with high infectivity. • Mortality rate is extremely high in chicken. • Depending on the virus strain responsible. • Practically, all avian species can be affected.
Clinical symptoms of ND Sudden death with few clinical signs • Respiratory symptoms • Nervous signs • Loss of appetite, depression, and lethargy • Dark greenish diarrhea • Decreased egg production There is a marked hemorrhage of the comb, wattle, and adjacent skin.
Zoonotic importance • Newcastle disease Newcastle Disease Virus (NDV) is highly contagious. • Transmission occurs by exposure to faecal and other excretions from infected birds, and through contact with contaminated feed, water, equipment and clothing. • Exposure of humans to infected birds can cause mild influenza-like symptoms and conjunctivitis, an abnormal eye discharge due to inflammation of the membrane lining the inside of the eyelid. • The infection can also cause nasal discharge, sneezing, and pneumonia. Left untreated, the infection tends to become chronic, lasting weeks or months.
