PurposeThe purpose of this paper is to analyze the attitudes of meat consumers in Rio Grande do Sul, Brazil, concerning cultured meat. This State is characterized by its strong cultural identity and social practices, barbecue being its typical dish.Design/methodology/approachThe authors applied a cross-sectional survey with meat consumers residing in Porto Alegre/RS, the sample of which, composed of 538 individuals, expressed the population heterogeneity. The data were analyzed using the Pearson chi-square, Cramer's V, and correspondence analysis.FindingsThe results demonstrate that although six of ten people were willing to try cultured meat, only four of them responded positively to the willingness to consume it over conventional meat. Young individuals demonstrated a favorable attitude towards the product, expressing a greater propensity both to try it and to include it in the diet regularly. However, the rejection of cultured meat gradually intensified after 40 years old. The previous knowledge and familiarity with the investigated subject are not predictive of the intention of experimentation so that almost two-thirds of the individuals who did not know the product were positively willing to try it.Originality/valueDespite the recent intensification of studies about consumer behavior towards cultured meat, its analysis in a context in which meat historically plays a fundamental role in socioeconomic development is still little explored. The originality of our research is circumscribed by the understanding of the behavior of meat consumers, members of a culture where it plays a central role.
This study aimed to investigate the effect of age at weaning of calves on nonesterified fatty acids (NEFA) and reproductive parameters of beef cows. Animals (n = 65) were randomly assigned to three treatments after calving: hyper-early weaning (W30) at 32 ± 0.89 days, early weaning (W75) at 77 ± 0.95 days, and conventional weaning (W180) at 183 ± 0.82 days. Body weight (BW) and body condition score (BCS) were evaluated at parturition (AP) and at 30, 45, 64, 81, 100 and 115 days postpartum (dPP). Blood samples were collected to analyze NEFA levels and progesterone (P4) at 30, 45, 64 and 81 dPP. Higher BW and BCS were observed from 64 to 115 dPP in W30 cows than W180 ones (p < 0.05). Cows subjected to W30 condition had higher levels of NEFA at 30 dPP compared to 64 and 81 dPP (p < 0.05). We also observed that cows from W180 group showed decreased levels of NEFA at 30 dPP compared to 45 (p < 0.01) and 64 dPP (p < 0.05).The highest P4 level was observed at 64 dPP in W30 cows compared to W75 and W180 (p < 0.05). We also observed higher CR of W30 (86%) compared to W180 (47%) at 45 dPP (p < 0.05). The overall pregnancy rate (PR) was higher for W30 (95.5%) than W180 (73.9%). In addition, higher BW at calving and P4 levels at 30 dPP were positively correlated with the possibility of pregnancy (p < 0.05).Improvement in BW and BCS were observed in cows subjected to hyper-early weaning management. However, levels of NEFA decreased as the postpartum period progressed. We concluded that cows who weaned calves hyper-early have greater chances of increasing cyclicity and PRs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
