In addition, quality traits (intramuscular fat percentage, color, pigment content, water holding capacity and shear force) were measured in LTL. Backfat fatty acid profile and intramuscular fat were also analysed. \u0000Main results: Significant differences were observed between groups for most of the fatty acids in backfat at 95 kg but differences were of lower magnitude at 160 kg and affected only to C16:1, C18:0, C18:1, C20:0, C20:1 and ΣSFA. Otherwise, lower values for red color and myoglobin content and higher for thawing water losses were observed for DOP pigs. The WCOC did not affect the analysed quality traits. \u0000Research highlights: Experimental diets did not have an important impact on growth, carcass composition or meat quality.

Incubation substrate was pre-digested in pepsin and pancreatin to simulate the processes occurring before the caecum. Pre-digested substrate was incubated alone or supplemented by three additives consisting of two commercial additives based on essential oils mixtures (CRINA-TEP and CRINA-TMEC) and riboflavin.

Only a trend for a higher ammonia concentration was detected with frozen than fresh inocula (p=0.062). Although not a main objective of the paper, gas production from the substrate alone (control) was lower than with riboflavin from 8 h onwards, and with CRINA-TEP from 4 to 10 h incubation (p>0.05). \u0000Research highlights: Caecal inoculum from pigs for in vitro fermentation studies can be preserved by freezing, provided that freezing and thawing processes are carried out under favorable conditions, especially in terms of time and temperature.","PeriodicalId":22182,"journal":{"name":"Spanish Journal of Agricultural Research","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2022-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46311221","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}
