Digestibility trials with poultry: The digestibility of dura, carobs and hide-fleshings

Digestibility trials with poultry were carried out with dura, carobs and hide-fleshings. 1. Dura equals the feeding value of corn and exceeds that of wheat, barley and oats. The high feeding value of dura is due to the large amount of easily digestible starch, and to the very small percentage of crude fibre. 2. Carobs. The main nutrient factor in carobs is represented by the totally digestible sugars contained in the N-free extract. Protein and crude fibre are not digested to any appreciable extent. The feeding value of carobs was compared with that of grain foodstuffs. 3. Hide-fleshings are a by-product of the tanneries. They contain 66·25 % of protein, which is digested by poultry like meat-meal protein (89·9 %). The authors wish to thank Mrs Gnessia Rabinovicz for her untiring assistance in the execution of these experiments.
