H.  aProtein-energy interrelationships in growth and lactation of cattle and sheep.h[electronic resource]  c1973  aAbstract: Only joint statements of protein and energy requirements are meaningful and there is some scope for interchange of the one for the other. In both applied and basic research, comprehensive studies of protein and energy need to progress simultaneously. Also the parallel effects for ruminant and simple-stomached animals should be explored. With energy being the principal quantitative limiting factor to output it is desirable to examine how far requirements for other nutrients can be calibrated in terms of the animal’s energy requirements (Kleiber, 1959; Balch, 1967). Rates of responses differ between cattle and sheep : this needs investigating further. Careful scanning of the relevant literature by Mr N. W. Briggs is gratefully acknowledged.  aBody composition  aBody weight  aCattle  aDigestion  aEnergy metabolism  aLactation  aMetabolism  aNitrogen  aNutrient requirements  aRuminant nutrition  aSheep  aConsumo  aCrescimento  aDieta  aLactação  aNutrição  aOvino  aProteína  aDietary Carbohydrates  aDietary Proteins  aNutritional Requirements  aPeso corporal  aRequerimentos  tProceedings of the Nutrition Societygv. 32, n. 2, p. 115-122, Sep. 1973.
