The two breeds produce light lambs in areas with high seasonality of pasture and high production costs. Moreover, Montesina breed is at risk of extinction. For this reason, it appears necessary to search different ways of diversification of their production, i.e., by adding a product of high added value, such as suckling lamb. The goal of this study was to evaluate the quality of Segureña and Montesina suckling lambs, at different seasons, with particular attention on the quality of carcass and meat. Twenty-four Segureña suckling lambs and 30 Montesina suckling lambs, single-born males and females, were used. Animals were grouped into two batches according to the breeding season: spring and autumn. The animals were exclusively fed with breastfeeding until they reached 10-16 kg of body weight. After sacrifice, we performed the analysis and measurements needed for calculation of standardized parameters of carcass and meat quality in this species. Overall, parameters of carcass-and-technological-meat quality showed adequate levels for both Segureña and Montesina suckling lambs. The statistical analysis showed a strong influence of breeding season in most of the quality parameters analyzed. The breed only marked significant differences in the fat state of the carcass (p = 0.01) and renal fat (p < 0.001), showing the Montesina breed the highest values. In conclusion, the Segureña and Montesina suckling lambs give carcass and technological meat characteristics of good quality. These results lead us to propose their production into farms in the Region of Murcia, in order to improve their economic viability.","PeriodicalId":54912,"journal":{"name":"Itea-Informacion Tecnica Economica Agraria","volume":"78 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2020-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85917680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Abstract The sheep meat sector is experiencing a strong recoil in Spain and in the European Union. It is a type of livestock that plays an important role in disadvantaged areas for its contribution to economic, social and environmental sustainability, being important to ensure its economic viability. The generic ob-jective of this work has been to analyze the possible relationship between the economic results of a sample of sheep meat farms located in Aragon (Spain) and certain structural indicators. Previously a typification was done to study their variability. The sample is made up of 126 Aragonese meat sheep explotaciones como más o farms. The variables’ means are used during a period that varies between 5 and 24 years within the 1993-2016 period. A factor analysis was performed on ten structural variables and four factors were identi-fied from which two significantly different groups of farms were obtained in terms of their structural characteristics. The gross margin per total labor unit was chosen as an indicator of the economic result of farms, and was calculated considering or not the remuneration of family labor. By means of a multiple linear regression the dependence of this economic result on structural variables previously analy-zed was established. It can be concluded that the optimization of the number of ewes per total labor unit and per hectare of the used agricultural area, are aspects to be considered when improving the profitability and viability of sheep meat farms.","PeriodicalId":54912,"journal":{"name":"Itea-Informacion Tecnica Economica Agraria","volume":" ","pages":""},"PeriodicalIF":0.4,"publicationDate":"2020-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42547083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
