Correlation between body measurements and milk production of goats in different lactations

Abstract

This paper presents the results of the variability and correlation of body measurements and milk production of domestic Balkan goat breed that is reared in the mountain range Sharplanina, depending on the lactation. Studied animals were monitored and lactation, or order of kidding (I, II, III and IV and the next lactation together). Control of milk production, included a total of 290 goats in different lactations (first-81 animals, the second-69 heads, 71 heads third-and fourth and following along latkacije-69 heads). In order to determine the measure of body development in adult goats, one takes values for height at withers, body length, chest depth, chest width, the width of the cross and body weight. The variability of the analyzed characteristics is presented descriptive parameters and the effect of lactation is determined by a factorial analysis of variance. The determined average values for milk production and measures of body development are located within those identified for this population of goats. During these tests showed statistically significant correlation dependence (P <0.05) between all studied variables, except when it comes to length lactation period and individual measures of body development. The correlation coefficient between length of lactation and established measures of body development. are low and reflect the existence uncorrelation dependence, and their values range from 0.08 to 0.11, while they were unjustified and statistically (P> 0.05).

A genome-wide association analysis for body, udder, and leg conformation traits recorded in Murciano-Granadina goats

“…For instance, HT was correlated with CW (r p = 0.65, P < 0.001), RW (r p = 0.67, P < 0.001), and ANG (r p = 0.42, P < 0.001); and CW showed positive correlations with BD (r p = 0.41, P < 0.001), RW (r p = 0.74, P < 0.001), and ANG (r p = 0.68, P < 0.001). Zujovic et al (2011) also observed high phenotypic correlations between body traits measured in Balkan goats, and Chacón et 2011) observed a similar trend in Cuban goats. In general, taller goats are also bigger and have a wider chest and rump.…”

Morphometric of Etawa Crossbred Goat in Breeding Stock Development Area in Banjarnegara District

“…Morphology can be considered as a selection criterion for the ideal body shape of dual purposes of goat. Morphometrics can explain the growth rates of the skeleton at various ages that could be considered as an early indicator of selection for milk production in dairy goat [3]. Body measurements differ according to factors such as breed, sex, yield type and age [4].…”

“…There current findings imply that udder measurements such as distance between teats, teat length and teat diameter can be used in improving milk yield. Similarly, Žujović et al (12) highlighted a relationship between breast width, breast depth, and milk yield of domestic Balkan goat breed that is reared in the mountain range Sharplanina. However, the study conducted in Pelibuey ewes (6) disagrees with the current study and stated that there was no correlation between teat length and teat diameter in the relationship between udder measurement and milk yield in Pelibuey Ewes.…”
