Lysine requirement for maintenance in growing pigs
Probably due to methodological problems the knowledge about the AA requirement for maintenance in pigs is rather scarce. In the present study an alternative experimental approach was applied and its underlying hypothesis was tested, whether protein retention decreases with body weight (BW), when daily lysine intake remains constant and acts as the limiting factor for protein retention, and whet...
متن کاملProtein level affects the relative lysine requirement of growing rainbow trout (Oncorhynchus mykiss) fry.
The effect of two digestible protein levels (310 and 469 g/kg DM) on the relative lysine (Lys; g Lys/kg DM or g Lys/100 g protein) and the absolute Lys (g Lys intake/kg 0.75 per d) requirements was studied in rainbow trout fry using a dose-response trial. At each protein level, sixteen isoenergetic (22-23 MJ digestible energy/kg DM) diets were tested, involving a full range (2-70 g/kg DM) of si...
متن کاملAssessing Lysine Requirement of Growing Chicken by Direct Comparison between Supplementation Technique and “Goettingen Approach”
Validated procedures play an important role to obtain accurate information about individual amino acid requirement data. The aim of the present study was to assess lysine (Lys) requirement of growing chicken both by classical supplementation technique and principles of diet dilution technique as applied with “Goettingen approach”. During the starter period (1 21 d), a growth study with male mea...
متن کاملEstimate of the variability of the lysine requirement of growing pigs using the indicator amino acid oxidation technique.
Although AA requirements for the mean in a population of growing pigs are well established, there are no direct estimates of their variability within the population. The indicator AA oxidation method allows repeated measurements in a short period of time so that the AA requirement can be determined for individual pigs. The objective was to determine the Lys requirement in individual pigs to der...
متن کاملCalcium requirement of growing rabbits.
T HE minimum calcium requirement of growing rabbits has not been determined. In practice dietary calcium levels have been based largely on information gained from other animals. Commercial rabbit diets commonly contain 0.8 to 1.0% calcium. Since the domestic rabbit is extensively used as an experimental animal and is increasingly used as a source of edible meat, particularly in the Los Angeles ...
