UNTERSCHIED KIES SPLITT TRIAL

Um den Einfluss eines protein-reduzierten Futters auf die Leistung, Nährstoffverdaulichkeit und Ganzkörperzusammensetzung von männlichen Zweinutzungshühnern zu überprüfen, wurde ein Versuch über 77 Tage durchgeführt. In conclusion, the data indicate that the dietary protein level can be reduced for the tested chicken strain, which would result in economic and environmental benefits without negative impact on animal performance and carcass quality.Įinfluss einer proteinreduzierten Fütterung auf Leistung, Nährstoffverdaulichkeit und Ganzkörperzusammensetzung bei Lohmann Dual Hähnenĭa die Tötung von männlichen Eintagsküken von Legehybriden in der öffentlichen Diskussion zunehmend kritisch gesehen wird, sind Zweinutzungs-Hühnerlinien, die Eier und Fleisch in ausgewogenerer Weise erzeugen, von großem Interesse. Whole body composition was similar between the groups and dietary protein restriction did not influence protein, fat, calcium and phosphorus levels. All data showed differences between control and the two low protein groups, but not between low protein groups, except for total digestibility of crude protein. Nutrient digestibility was similar between groups. However, no difference between the feeding regimes could be detected within the groups of high and low performing birds.

Within the groups data followed a normal distribution, but analysing the individual weights of the animals showed a split development with a clear difference in the growth rate of high and low performing birds. P=0.038), but this did not affect overall performance. Weight gain and feed intake differed only by dietary protein content in the grower period Weight gain, feed intake and feed conversion rate were not affected in the overall feeding period. A total of 480 male Lohmann Dual chickens were randomly allocated into 24 experimental pens, the diets were offeredĪd libitum to 8 replicates with 20 chickens. Three isoenergetic diets were formulated to provide three levels of protein, respectively, in each phase: 23.0, 22.1 and 20.4% CP in the starter phase (1 to 14 d) 21.6, 20.3 and 19.2% CP in the grower period (15 to 28 days) and 19.4, 18.6 and 17.5% CP in the finisher diet (29 to 77 days).

UNTERSCHIED KIES SPLITT TRIAL

A trial was conducted to determine the effect of protein restriction on performance, nutrient digestibility and whole body composition of male dual-purpose chickens from 1 to 77 days of age. As killing of day old male chickens of layer breeds becomes a greater concern in the public discussion, dual-purpose chicken hybrids, producing both eggs and meat, are of high interest.
