In sheep production, obtaining twins is a key strategy to improve farm productivity. However, twin lambs are born lighter and smaller than singletons, which is associated with higher perinatal mortality, therefore the profitability of the productive system can be reduced. The intrauterine development of the offspring depends mainly on their genetic potential and the availability of nutrients and oxygen. The transfer of nutrients and gases between the maternal-fetal compartments responds to utero-placental blood flow and placental capacity (sufficiency), so that maternal undernourishment and placental insufficiency can adversely affect the development of the offspring by compromising the nutrient and/or oxygen influx. This study was conducted on 60 corriedale bred sheep, separated by pregnancy rank (singleton or twin bearing). The sheep in this study underwent two nutritional plans from day 30 until the end of gestation, one that covered ~70% and another ~ 100% of the energetic-protein requirements of the pregnant sheep. The weight and body condition score of the sheep were evaluated every 30 days. At 100 and 140 days of gestation, caesarean sections were performed. Blood samples were collected from the umbilical vein of each fetus to evaluate variables associated with fetal oxygenation (PO2, PCO2, hemoglobin saturation with oxygen, hematocrit and pH). Fetal morphometric parameters were also measured (crown-rump length, thoracic perimeter, arm and leg length). Additionally, at 140 days of gestation, an evaluation of placental weight and morphology was performed. The results were evaluated by analysis of variance (ANOVA), where the fixed factors were the number of fetuses in gestation (single or twins) and the nutritional level (~70 or ~100% of the requirements established by the NRC), followed by the post-hoc Duncan test. Significant differences were considered at p≤0.05. At 100 days of gestation, no differences were evident in any of the variables studied. At 140 days of gestation the weight of the ewes fed with the control diet (~100% NRC) was greater than that of the ewes fed with the restriction diet (~70% NRC). The ewes from the single gestation control group (SC) had the highest body condition score when compared with the other groups. Twin-bearing ewes had higher values of total placental weight per sheep and a greater number of placentomes per sheep than those of single-gestation ewes. The single-gestation ewes had higher values of total placental weight per fetus and more placentomes per fetus than twin-bearing ewes. The predominant type of placentome in all groups were A and B, with a lower proportion of C and D. Fetal oxygen concentrations were higher in the single gestation control group (SC) compared to the other experimental groups. In addition, there was a positive correlation (r = 0.459) and statistically significant (p = 0.013) between the PO2 obtained from the umbilical vein and fetal weight at 140 days of gestation. All singletons were heavier than the twins...

Enriquecimiento de helado con triacilglicéridos estructurados de epa, dha y ácido caprílico, de acidólisis enzimática (Candida antarctica) de AGPICL n-3 y aceite refinado comercial de salmónidos
(Universidad de Chile, 2017)
Hoy en día, los aceites de origen marino son productos valiosos con gran aplicación nutricional por su alto contenido de ácidos grasos poliinsaturados de cadena larga omega-3 (AGPICL n-3), principalmente el ácido eicosapentaenoico (C20:5, EPA) y el...
Nowadays oil from marine origin are valuable products with great nutritional application due to their high content of omega-3 long chain polyunsaturated fatty acids (AGPICL n-3), mainly eicosapentaenoic acid (C20: 5, EPA) and docosahexaenoic acid (C22: 6, DHA). These fatty acids are known for their multiple health benefits, being associated with protection against cardiovascular, the optimal development of neural, regulating imflammation, and others. However, the consumption of seafood in Chile is quite low with respect to the world average, due to the above, the present work studied the enrichment of a cream matrix of ice cream with the addition of EPA, DHA and caprylic acid structured triacylglycerols (TAGs), obtained from the purification of the product generated in the enzymatic acidolysis process (Candida antarctica) of commercial refined oil of salmonids and concentrate of AGPICL n-3 of commercial crude oil of salmonids under conditions of supercritical carbon dioxide. The commercial crude oil of salmonids AGPICL n-3 concentrate was obtained by saponification and subsequent inclusion with urea crystals for the exclusive production of AGPICL n-3, EPA and DHA. The enrichment of ice cream was carried out with the addition of EPA and DHA TAGs by optimizing the variables of the homogenization process, EPA and DHA concentration and stirring speed using a factorial design 22 with 2 repetitions at the center point of the coded variables (0,0) according to response surface methodology. The effect of the homogenization process on thermal behavior was studied by differential scanning calorimetry (DSC) for the variables response mouth melt measured at 10°C and thermal resistance measured at 0°C. The values obtained for the optimization of the response variables, mouth melt and thermal resistance with respect to control ice cream were 6056 rpm for the agitation speed and 151 mg of EPA and/or DHA TAGs in the enrichment of the cream in the ice cream matrix. So this study allows to complement the intake of fish with a product of mass consumption, besides representing an approach to the optimal levels of omega-6 and omega-3 fatty acids in a food especially attractive for children...
