Thus, in recent years there has been a commitment to replace the protein component of feed with more sustainable vegetable alternatives. The experimental design from which this study is derived consisted of substituting organic fish meal with different percentages of organic soybean meal and pregerminated soybean meal. Therefore, the objective of this study was to evaluate the potential of Near infrared spectroscopy (NIRS) in categorizing tench according to the feed they received during its fattening phase and the quantification of the main nutritional parameters. Different spectral pretreatments were used previous to the partial least squares regressions for qualitative (PLS-DA) and quantitative (PLSR) predictions. The best PLS-DA model showed an accuracy for classification of 97.5 % in cross-validation; while the best PLSR model showed a good predictive capacity for dry matter (g/100 g), fat (g/100 g Dry Matter), and γ -tocopherol (mg/g dry matter) (0.689 ≤ R 2 vc ≤ 0.804), suggesting the possibility of performing a rapid and in situ control of the traceability and quality of tench meat by means of NIRS technology.","PeriodicalId":516767,"journal":{"name":"Informacion Tecnica Economica Agraria","volume":"14 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140525285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main objective of this study was to improve the knowledge about body reserves (backfat thickness and loin depth) in a commercial farm with hiperprolific sows. On a total of 283 sows of different parities, backfat thickness and loin depth were recorded at the day of insemination, at days 40 and 110 of gestation, and at weaning. Thus, the effect of parity and the effect of lean-to-fat ratio (categorized into three groups according to their 25th and 75th percentiles: Low, Medium and High) on body reserves during the whole period were evaluated; as well as its potential impact on some reproductive parameters. Gilts showed a lower fat deposition than primiparous and multiparous sows, mainly in early gestation; in addition, they had a greater loss of the loin during the lactation and the whole productive period. Regarding to lean-to-fat ratio, gilts with higher vs. lower ratio showed greater losses of backfat and loin depth during lactation. Backfat gain during the productive cycle was lower in primiparous and multiparous sows with the highest ratio; while during mid and late gestation, the loss of loin depth was lower than sows with the lowest ratio. Moreover, the initial values of backfat and loin depth presented a high and moderate positive correlation with their own backfat and loin depth values (during the whole period); however, the cross-correlation between backfat and loin depth was lower or null, highlighting the importance of measuring both. From a reproductive point of view, primiparous and multiparous sows with the highest lean-to-fat ratio showed the highest culling rate. The results underline the need for specific feeding management according to parity (nuliparous vs. primiparous and multiparous). The study also suggests that periodic measurements of backfat and loin depth are a useful tool that allows nutri - tionists to evaluate the feeding plan applied to each farm. Thus, the establishment of recommendations for the lean-to-fat ratio, on the one hand, would provide a more objective unit of measurement on the nutritional status of sows; and, on the other hand, would allow adjusting an adequate nutrient intake at each stage of the productive cycle of hyperprolific lines.","PeriodicalId":516767,"journal":{"name":"Informacion Tecnica Economica Agraria","volume":"167 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139640857","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The 99 dairy farms in the study were classified according to the percentage of green forage as a percentage of dry matter in the spring diet of lactating cows: herds without green forage (<25 %, NFV) and with green forage ( ≥ 25 %, FV). A multiple correspondence analysis was carried out to examine the relationships between this diet, the main productive characteristics and some territorial variables with statistical significance ( p < 0.05). The results showed that dairy cattle farms in the group ( ≥ 25 % FV) are characterized by smaller territorial size, herd size, stocking rate, annual production and concentrate utilization while spending more on grazing. From a territorial point of view, they are located at a higher altitude, have larger, more continuous and geometrical plots, but also a soil with a lower agricultural quality. The multiple correspondence analysis showed a strong association between diet and productive variables, less intense in the case of territorial variables.","PeriodicalId":516767,"journal":{"name":"Informacion Tecnica Economica Agraria","volume":"22 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140519408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
