Broiler feeding

Broiler chicks require broiler starter feed for the first four weeks of their life. The broiler starter feed should be at least 20 per cent protein, preferably 23 per cent protein. After four weeks, you should feed a 19 per cent protein feed.

2. A broiler ; Is a hybrid chicken reared intensively for meat purposes produced by crossing of parents belonging to two distinct breed or strains They are sent to the market within 42 days at average weight at 2kg.

3. Broiler Feeding Broilers convert feeds to meat within a very short period of time. Therefore quality feeding is important in broiler management . Sufficient nutrients are required for appetite development during the first 72-96 hours To develop different physiological systems (cardiovascular, alimentary tract … etc ) For fast growth and muscle development of the broilers To prevent stress conditions in first few days To promote health conditions

4. Nutrients requirements depend on ; Age and size Production level Energy content of the ration Physical form of diet Nutritional adequacy of the diet Environmental temperature

5. Energy concentrates – corn, milling by-products, sorghum… Protein concentrates plant protein sources - soybean meals and other oil seed meals animal protein sources –meat and bone meal, fish meal Water Feed additives : Nutrient feed additives : vitamin and mineral supplements , Essential Amino Acids Non nutrient feed additives : antibiotics , coccidiostats , anti oxidants, enzymes, prebiotics and probiotics Feed Ingredients

6. Proteins : adequate amount of protein is very much important due to their fast growth and weight gain . Carbohydrates & fats : Provide metabolisable energy (ME), fuel for body function Minerals : important for proper body functions Vitamins : important role in metabolism, require in small quantities water : For heat removal Digestion and formation of body tissues Importance of nutrients

7. Mainly there are two rations in broiler feeding. Broiler starter (Day 1 to 21) Broiler finisher (Day 22 to slaughter ) Broiler starter Highest quality feed Important in establishing good appetite and maximum early growth Contain more protein : 21-23% (SL 20-21%) Metabolisable Energy – 3200 kcal/kg of diet Crumble form Ad libitum feeding Should contain; Coccidiostats Feed additives (growth promoters)

8. Broiler finisher Lesser protein than starter Protein content : 20% (SL18%) Metabolisable Energy – 3200kcal/kg of diet Pellets form Ad libitum feeding Contain feed additives Feeding process should be stopped at 12-18 hours before slaughtering. Reasons : Ease of handling and transportation Empty the digestive tract – lower the chance of spoilage Reduce feed cost

9. Ad libitum feeding Restricted feeding Poor health control Reduced variation in body weight and growth Uniform growth Less carcass quality Poor FCR More digestive problems Less laborious Less consumption of feces Higher calming effect Ad libitum feeding versus Restricted feeding Better health control Increased variation in body weight and growth Unequal growth Good carcass quality Better FCR Less digestive problems Higher labarious High consumption of feces Less calming effect

10. Other than those feeds; Vitaguard solution (multivitamin- Bio vitamin oral solution 1ml per 1l) Selvit E (vitamin E oral solution) Enrocip oral solution (10% wv ) were provided. Provide water and feeds twice a day.

11. Feeders & Drinkers For feeding of broilers; following types of feeders can be used. Automatic Linear Circular For watering; following types of drinkers can be used. Bell Nipple Linear Conventional Feeders and drinkers should be in hygiene condition.

12. • Sufficient feeding space has to be provided, depending on their age • 0-2 weeks - 3 cm • 3-4 weeks - 5 cm • > 4 weeks - 8 cm • Height of the feeder should adjusted

13. Sufficient drinker space has to be provided, depending on their age • 0-2 weeks – 1.3cm • 3-5 weeks – 2.5 cm • > 5 weeks - 5 cm • Height of the feeder should be adjusted
