Abstract

(vacas -1 (kg PV ha -1 año -1 ; p < 0,0001) y producción de carne total (kg PV ha -1 -1 < 0,0001). Los tecnificados que ABSTRACT The productive characterization of livestock systems is a key aspect when designing management plans aimed at increasing beef production in a region. 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.
阿根廷中北部地区技术牛养殖系统的生产特征
(空置量-1(kg PV ha-1 año-1;p<00001)和卡内总产量(kg PV ha-1-1<00001。在设计旨在提高一个地区牛肉产量的管理计划时,牲畜系统的生产特征是一个关键方面。这项工作的目的是表征技术化的奶牛-小牛系统农场。描述性统计和多变量分析的显著性水平为p≤0.05。与该地区的典型系统相比,调查农场的放养率(奶牛公顷-1)、断奶率(%)和牛肉产量(公斤LW公顷-1年-1)分别高出15%、38%和84%。养殖种面积越大,妊娠率(p=0.0269)和断奶率(p=0.0051)呈正相关,奶牛的补充水平(p=0.00259)与放养率(奶牛ha-1)呈正相关。此外,放养率(奶牛ha-1)与较高的小牛产量(kg LW ha-1年-1;p<0.0001)和总牛肉产量(kg LW ha-一年-1;p<0.0001。
