POULTRY FEEDS AND FEEDING 



Feed this mash three times daily, or use a mash of three 

 parts corn meal, one part low-grade wheat flour, one part 

 bran, 5 per cent meat scrap, and 3 per cent oyster shell, 

 with the green feed and grit added. The green feed is 

 sometimes left out of the ration during the last seven 

 days of fattening, but it is easier to keep the ducklings in 

 good feeding condition on a mash containing green feed. 

 Boiled fish may replace the meat scrap, but should only be 

 fed up to within 2 weeks before they are killed, as it may 

 give a fishy taste to their flesh. A considerable quantity of 

 boiled fish is also fed in the mash to laying ducks in sec- 

 tions where the duck farms border on the water and where 

 fish are available at a very small cost. This fish aids 

 materially in reducing the cost of feeding. 



Green ducks are marketed at from 8 to 12 weeks of 

 age, according to their condition and weight. Two or 3 

 per cent of oyster shell is recommended in most fattening 

 rations, but bone ash, ground or cracked bone, or bone 

 meal would appear to be better mineral feeds to add to 

 these mixtures. If milk is available at profitable feeding 

 prices, the rations recommended for crate- fattened 

 chickens would give good results in fattening ducklings, 

 producing a well-bleached, milk- fed green duck. Celery 

 seed may be used in fattening ducklings, as it is said to 

 flavor the flesh, but its use is not general. 



FEEDING BREEDING AND LAYING DUCKS 



Breeding ducks, if not kept for the production of mar- 

 ket eggs, should have a grass range if possible after the
