Název v původním jazyce

The effect of the extrusion process on the digestibility of feed given to laying hens

Popis výsledku v původním jazyce

The purpose of the study was to observe the effect of feeding extruded feed that contained rapeseed (that was extruded using the standard methods for large-scale production of extruded feed) on retention and coefficient of total tract apparent digestibility (CTTAD) in hens. The laying hens were divided into two groups NEX and EXT. The composition of the diets was the same in both groups (wheat 39%, rapeseed 13.5%, pea 13.5%, soya bean meal 6%, maize 14%, fish meal 3%, limestone 1%, premix 10%). But 0.45kg of 1 kg of the diets EXT (wheat, pea and rapeseed) was extruded by dry extrusion at temperature 137 °C and at moisture from 12 to18% for 6s. A balance assay was conducted with four laying hens from the group NEX and eight from the group EXT when theywere 61 week old. The CTTAD of fat, calcium and amino-acids, and the retention of the nitrogen were estimated using the indicator method. The significance between the means was evaluated by a t-test. The average egg mass production durin
