CARACTERIZACIÓN PRODUCTIVA DE SISTEMAS DE CRÍA BOVINA TECNIFICADOS DE LA REGIÓN CENTRO NORTE DE ARGENTINA

Abstract

The objective of this work was to characterize technified cow-calf systems farms. Descriptive statistics and multivariate analyzes were performed at a significance level of p ≤ 0.05. Stocking rate (cows ha -1 ), weaning rate (%) and beef production (kg LW ha -1 year -1 ) of the surveyed farms were 15, 38 and 84% higher, respectively, compared with typical systems of the region. The higher area with cultivated species was positively correlated with pregnancy rate (p = 0.0269) and weaning rate (p = 0.0051). Supplementation level of cows (p = 0.0259) was positively associated with stocking rate (cows ha -1 ). Furthermore, stocking rate (cows ha -1 ) correlated positively with higher calf production (kg LW ha -1 year -1 ; p < 0.0001) and total beef production (kg LW ha -1 year - 1 ; p < 0.0001). Technified farms showed a better productive performance compared to that of typical cow-calf systems in the region studied.
