Question 19

7 ADVANTAGES OF PELLETING

Answer 19

a) less feed loss to wind

b) reduces feed dustiness

c) keeps all ingredients bound in pellet form during handling

d) Destroys bacteria in feeds (e.g., salmonella)

e) Increases feed density, allowing chicken to consume more low energy feeds

f) Marked Increases consumption of feed ingredients that are otherwise, unacceptable to chickens when they are not pelleted

g) Less feed wastage from feeders

Question 20

DISADVANTAGES OF PELLETING

Answer 20

a) Added cost of pelleting

b) Wasting of fine particles when pellets break into crumble

c) Increased water consumption of broiler chicken that often result to wet droppings

d) Increased incidence and severity of cannibalism

Question 21

(6) The following are observed responses of broilers to pelleting or crumbling broiler feeds:

Answer 21

a) Pelleting of high-fiber feeds shops more improvement in feed consumption than pelleting low-fiber.

b. Pelleting reduces the feeding time of chickens.

c. Pelleting per se does not increase the growth rate of broilers. Pelleting increases feed consumption, which is often translated into fast growth rate.

d. From day-old to 2 weeks, chicks cat more feeds in mash form than crumbles or very small pellets, but thereafter, pellet feeds are preferred.

e. When mixture of three-fourth pellets and one-fourth mash is given, some broilers show preference for mash and some for pellets. This practice results in greater average body weight than when pellets alone are fed.

f. If pellets are too large, acceptance will be reduced.

Question 43

Management Practices to Avoid Feed Losses in Feeders
The following are some tips to minimize feed wastage:

Answer 43

1. Avoid filling beyond one-third of the capacity of the trough feeders.
2. Use the right size of feeder for a particular age of chickens. Each feeder
   should have a guard or lid to avoid the feed from being beaked out.
3. Keep the brim of feeder’s level with the back of the chickens to reduce
   wastage from beaking out foods and make eating easier for the chickens.
4. Give pelleted or crumbled feed instead of mash feed if the cost is reasonable.
