Abstract

 

Canonical correlations among nutrient intake (energy, protein, Acid Detergent Fiber (ADF), Neutral Detergent Fiber (NDF) and dry matter intake (DMI)) and body weight, milk yield (MY) and milk component in 36 German Fawn x Hair Crossbred goats under different feeding systems were estimated. Canonical correlation coefficient between the first (0.91) pair of canonical variables was significant (P<0.01). There was an important relationship between milk yield and nutrient based on Pearson correlation. The highest contribution for the explanatory capacity of X variable sets was DMI and MY. DMI (most impressing) and MY (most responded) during the last lactation period appear to be a determining factor for estimating performance of German Fawn x Hair Crossbred goats.
