The aim of this study was to evaluate intake, digestibility, rumen kinetics, and blood metabolites in hair lambs fed Samanea saman and Cordia dentata. Twelve hair lambs were distributed in an experimental 4x4 Latin square design, with four treatments and four experimental periods. Treatments were T1:100 % Dichanthium spp hay, T2: 80 % Dichanthium spp hay, 20 % S. saman, T3: 80 % Dichanthium spp hay, 20 % C. dentata, T4: 80 % Dichanthium spp hay, 10 % S. saman, and 10 % C. dentata. The highest nutrients intakes were obtained with diets containing tree foliage compared with the T1 diet (p< 0,05). In vivo and In vitro digestibility of DM, OM and, NDF of tree leaves diets showed higher values than the T1 diet (p<0,05). Digestible and metabolizable energy were similar between tree leaves diets (p<0,05). Blood urea nitrogen values were superior for animals fed the T2 diet (p<0,05). Degradability values at 96 hours were higher for the T2 diet (p<0,05). Potential degradability was superior for the T3 diet. The results of this study demonstrate that S. saman and C. dentata leaves improve nutrients intake and digestibility. Therefore, they can be an alternative for sheep in the tropical dry forest.","PeriodicalId":56220,"journal":{"name":"Biotecnologia en el Sector Agropecuario y Agroindustrial","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42993090","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}

Este trabajo se enfocó en evaluar la bioaccesibilidad de Cd en formulaciones de chocolatería con concentraciones de componentes diferentes por digestión gastrointestinales in vitro. Esta digestión se realizó a través de un titulador automático con control de temperatura, y control y monitoreo de pH mediante soluciones diluidas ácidas y alcalinas. Se correlacionaron las diferencias de bioaccesibilidad con los componentes principales (cacao, leche, azúcar y contenido de Cd total en el cacao) y, por último, se propuso una formulación de chocolate que tuvo el menor valor de bioaccesibilidad de Cd. Los resultados se expresaron mediante un modelo matemático, con predicciones de 94 % y errores de validación del modelo menores que 9 %. Se obtuvieron valores de bioaccesibilidad de Cd en las formulaciones de chocolate entre 7 y 32 % aproximadamente, donde los valores más bajos correspondieron a formulaciones de chocolate amargo (relación másica cacao:azúcar de 7:2). Se concluyó que el contenido de cacao y de azúcar en la formulación disminuyen los valores de bioaccesibilidad de Cd, mientras que el contenido de leche y la concentración de Cd total en el cacao aumentan los valores de bioaccesibilidad.","PeriodicalId":56220,"journal":{"name":"Biotecnologia en el Sector Agropecuario y Agroindustrial","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48151072","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 lactic acid bacteria content in milk and Paipa cheese, the coagulant and lipolytic activity of the enzymes, the lipid composition as well as the lipid profile of the product, total free fatty acids, and sensory analysis were evaluated. The results indicated a greater lipolysis in cheeses made with microbial clotting enzymes which were associated with a greater lipolytic activity and a greater perception of acidic, rancid, and soapy flavors. Nevertheless, panelists preferred cheese prepared using recombinant chymosin, with lower lipolysis and lipolytic activity. Regardless of the type of protein precipitant that can be used in the elaboration of semi-matured and matured cheeses, Paipa cheese had a high content of saturated fatty acids and omega 3, 6, and 9; which accounted for the organoleptic and nutritional characteristics, which could favorably impact its commercial activity.","PeriodicalId":56220,"journal":{"name":"Biotecnologia en el Sector Agropecuario y Agroindustrial","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43156795","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}

It was evaluated how the modification of the shade canopy (full sunlight exposition systems SLE and agroforestry with MPAR medium and low BPAR transmitted radiation) affects the water status of cocoa trees in contrasting periods of precipitation. For the measurement of Vs and Ѱ heat sensors and stem psychrometers were installed in cocoa type CCN51 trees. An effect of the production system and monitoring season on Vs and Ѱ was found in cocoa plants. The Ѱ was higher in SLE in both seasons, but it was more accentuated in the period of minimum precipitation. A contrary behavior was found in Vs, since in minimum precipitation this variable was greater in BPAR.

To determine the influence of fruit ripening, and seed extraction from the fruit on seed germination of a Venezuelan type of Capsicum chinense, a factorial experiment with 10 replications was conducted. Influence of the six combinations between three fruit maturation levels (green fruits, early-ripe fruits, and totally-ripe fruits) and two seed extraction moments of seed from the fruits (at the same day of the harvest and seven days after the harvest) were evaluated on seed germination percentage and days number to germination. Each replication consisted of 100 seeds, and seed germination was recorded for ten days. Results displayed no interaction between fruit ripening and extraction of seed for both dependent variables, but significant differences (P<0,01) were recorded for germination percentage among fruit ripening levels (the same for totally yellow and fruits changing color, but higher than green fruits), and between separation moment of seed from the fruits (seven days after the harvest resulted in 80% more germination rate as compared to seed separated at the same day of the harvest). Significant differences (P<0,01) were recorded also for the number of days to germination: seeds extracted from earlyand totally-ripe fruits did not have significant differences (P>0,05) and germinated in 7,30 days in average, but they germinated faster (P<0,01) than seeds coming from green fruits which germinated in 8,40 days in average; seeds extracted from fruit 7 days after harvest germinated in 6,50 days in average, faster (P<0,01) than seeds extracted from the fruit the same day of harvest (8,75 days in average).
