To quantify the effects of castration in male beef cattle on welfare indicators based on cortisol concentration, average daily gain (ADG) and vocalization, a systematic review and meta-analysis were performed.We searched on five electronic databases (CAB Abstracts, ISI Web of Science, PubMed, Agricola and Scopus) from January 1900 to May 2015 and included conference proceedings and electronically contacted experts, as well as we checked references of relevant review papers. Inclusion criteria were complete studies using beef cattle until one yearof age undergoing castration that analysed cortisol level, ADG or vocalization.Data were extracted using pre-defined protocols. The included documents were written in English, Spanish, Portuguese or Italian.Random effect meta-analyses were conducted for each indicator separately with the mean of control and treated group. Possible influences of study characteristics and quality were assessed in meta-regression analyses.A total of 18 prospective publications reporting 23 studies and 156 trials were included in the MA involving 1,617animals.Significant between studies heterogeneity was observed for MA results when analysing cortisol and ADG.Regardless the control group and the castration technique, the comparison analyses showed no changes (P ? 0.05) on cortisol levels when castration was performed without drug administration.We found no evidence (P ? 0.05) for multi-modal therapyin decrease cortisol concentration 30 min after surgical procedure.Anaesthesia did not decrease cortisol level (MD = 0.411 nmol/L; P = 0.077; 95% CI: -0.868, 0.045) 120 min after surgical castration compared to castrated group without drug administration.Random-effect meta-analysis suggested an increase in ADG in surgical (MD = 0.231 g/d; P = 0.010; 95% CI: 0.056, 0.405) and non-surgical castration (MD = 0.883 g/d; P < 0.001; 95% CI: 0.313, 1.453) with no pain mitigation in comparison to uncastratedcattle.Publication bias was observed when cortisol was studied as an outcome, indicating that small size studies reporting non-significant effect were less likely to be published than similar studies with significant effect. In a meta-regression, only publication type contributed to the total variation (18.52%) when the outcome evaluated was ADG. The vocalization score presented data in a manner that was not suitable to MA. Our MA study demonstrates an inconclusive result to draw recommendations on preferred castration practices to minimize pain in beef cattle.

ABSTRACT: The objective of this study was to evaluate the bioeconomic efficiency of beef cattle production systems in the south of Brazil. A
survey was conducted with 33 beef cattle farmers operating with complete cycle production systems in areas larger or equal to 900 ha. Answers
were classified in two drivers, technology (TEC) and management (MAN), which were separated into subfactors with their respective components.
Multiple correspondence analysis, Tukey test, cluster analysis, and Pearson correlation were the statistics procedures. The TEC components were
above normal for Brazilian farmers, but the gross margin is still lower than that needed to generate financial resources for a proper remuneration
of cattle farmer. Farmers were classified into three clusters according to bioeconomic efficiency: low (LEL), intermediate (IEL), or high-efficiency
level (HEL). The TEC driver differentiated the LEL x HEL clusters and the MAN, mainly expressed in costs, the IEL x HEL. Positive correlation
between age at first mating and age at slaughter in the HEL cluster explains the higher costs when compared to IEL because of the use of
differentiated feed resources. Investments in technologies related to herd feeding in HEL cluster improved the productivity by only 20% and the
cost per hectare by 95 USD ha-1 in comparison to IEL cluster. The main differences between farmers are because of the use of technologies related
to feeding and cost management. Therefore, before implementing a new technology, an economic evaluation is necessary.
RESUMO: O objetivo deste estudo foi avaliar a eficiência bioeconômica em sistemas de produção de bovinos de corte no sul do Brasil. A pesquisa foi realizada com 33 pecuaristas que operam com sistemas de produção baseado em ciclo completo, em áreas maiores ou iguais a 900 hectares. As respostas foram classificadas em dois fatores: tecnologia (TEC) e gestão (GES), os quais foram separados em subfatores com seus respectivos componentes. A análise de correspondência múltipla, teste de Tukey, análise de cluster e correlação de Pearson foram os procedimentos estatísticos. Os componentes do TEC estavam acima do normal para os pecuaristas brasileiros, mas a margem bruta ainda é menor do que a necessária para gerar recursos financeiros para uma remuneração adequada ao pecuarista. Os pecuaristas foram classificados em três grupos de acordo com a eficiência bioeconômica: baixo (BNE), intermediário (INE) ou alto nível de eficiência (ANE). O driver TEC diferenciou os clusters BNE x ANE e o GES, expresso principalmente em custos, o INE x ANE. A correlação positiva entre a idade no primeiro acasalamento e a idade ao abate no agrupamento ANE explica os custos mais elevados quando comparados aos INE, devido ao uso de recursos alimentares diferenciados. Os investimentos em tecnologias relacionadas à alimentação de rebanho no agrupamento ANE melhoraram a produtividade em apenas 20% e o custo por hectare em 95 USD ha-1 em comparação ao cluster INE. As principais diferenças entre os pecuaristas se devem ao uso de tecnologias relacionadas à alimentação e ao gerenciamento de custos. Portanto, antes de implementar uma nova tecnologia, uma avaliação econômica é necessária.
