The relationships among growth traits in different ages of 232 heifers Southern Meat Cattle (SMC) breed and genotype and environmental factors were studied using a multifactorial ANOVA, and additionally with a entropy and information analysis (EIA).
The traits evaluated were birth weight (BW), weaning weight (WW), weight at year (YW) and weight at 15 (М15), 18 (М18) and 24 months of age (M24). The 21-year period studied (year of heifer’s birth from 1986 to 2006) was classified into three periods as follows: Gen1 – 1986-1992, Gen2 – 1993-1999, Gen3 – 2000-2006. Experimental heifers originated from four sire lines – Ideal 133, Sanil 8, Loksher 302 and Signal 475.
Firstly, we tested the hypotheses that weight traits were influenced by the sire line (factor ‘Origin’) and by of heifer’s year of born (factor ‘Generation’). Differences between groups were evaluated with a three-factorial ANOVA (with ages as a repeated measures factor). All statistical analyses were performed using STATISTICA (StatSoft Inc., USA).
A repeated measures ANOVA revealed significant main effects for generation, F2; 218 = 15.50; p < 0.001, and age of heifers, F5; 1090 = 2064.91; p < 0.001. Additionally, there was a significant interaction between generation and age of heifers, F10; 1090 = 15.55; p < 0.001 and between generation, origin and age of heifers, F30; 1090 = 1.94; p = 0.002.
The lowest entropy values were associated with BW, which did not depend on heifer’s origin and generation (in both cases: p > 0.05). This may be due to the long period (near 20 years) of successful breeding program with the SMC breed.
Key words: entropy and information analysis (EIA), growth traits, heifers, beef cattle.
