Aussagefähigkeit von Funktionen zur Approximation des Massewachstums von SMR-Bullen

Experimental results of an individual feeding experiment with 48 Holstein-Frisian heifers were generalized with regard to live weight development and energy intake by means of the Janoschek function and the extended e-function resp. The requirement of metabolizable energy was derived from the results of energy intake on dependance on live weight and live weight gain. In comparison with the data of the NRC (1978) a requirement by 10% lower was the result. Due to adding a 10% deficiency supplement at present required under Cuban conditions of production the use of the NRC recommendations (1978) is still justified. Without the addition of the deficiency supplement the results showed good agreement with requirement data of INRA 1978.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
