“…According to Turan et al (2007), lower AI and TI translate into more anti- Fatty acids profile atherogenic FAs and better disease prevention profiles. Nevertheless, it should be remarked that the determined levels are in accordance with the ranges previously reported by other researchers for ewe, goat and cow cheeses (Aguilar et al, 2014;Cabiddu et al, 2006;G omez-Cortés et al, 2009;Oliveira et al, 2015;Rodrigues et al, 2012;Taboada et al, 2015;Vargas-Bello-Pérez et al, 2013a, 2013b. Moment of manufacturing presented low AI and TI and the R(v -6)/R(v -3) values were below recommended level (less than 4.0) thus differences observed might be attributed to differences in animal's feed (location in de region) and to the producer.…”

“…Indeed, low values of AI, TI and R(v -6)/ R(v -3) are highly desirable as well as higher values of DFA, SCFA and MCFA. Several researchers reported the AI values for different types of ewe cheese (0.84 for supplemented diet to 5.57 for no supplemented diets) showing that sheep diet supplementation allowed a decrease of the AI values (Cabiddu et al, 2006;G omez-Cortés et al, 2009;Vargas-Bello-Pérez et al, 2013a, 2013b). For commercial ewe cheese, Aguilar et al (2014) found mean AI values of 2.33-2.63, TI values varying within 2.81-3.10 and, R(v -6)/R(v -3) ratios ranging between 3.79 to 6.45, which were similar to those previously reported in the literature for ewe cheeses.…”

Purpose This study aims to determine the physicochemical and fatty acids composition of Serra da Estrela cheese (SEC), as well as health-related lipid indices, like the atherogenic and thrombogenic indices, and to evaluate the influence of producer, geographical origin and production date. Design/methodology/approach All 24 SEC produced between November 2017 and March 2018 were collected at selected certified producers and analyzed by NIR spectrophotometer and by GC. Data were statistically evaluated by chemometric tools. Findings In all evaluated SEC, 23 fatty acids were quantified. Cheese origin influenced nutritional and health-related lipid indices). The cheeses were characterized by a relative high abundance of saturated fatty acids (67-76%), followed by a medium content of monounsaturated fatty acids (17-25%) and by low level of polyunsaturated fatty acids (5-7%). A putative positive association between cheese consumption and healthy lipid indices could be reached. Practical implications The contents of some medium and long chain fatty acids as well as of nutritional and health indices were influenced by cheese producer, geographical origin and production date pointing out the need for standardizing production procedures. Social implications The SEC plays a key role in the local economy, being an endogenous product with unique sensory characteristics and nutritional potential, for which the knowledge of the lipids profile and health indices is of utmost relevance. Originality/value SEC is an iconic Portuguese cheese with Protected Designation of Origin. Based on the results, like health-related lipid indices, evaluated for the first time, a positive association between cheese consumption and healthy lipid indices could be envisaged.

“…It is known that in small ruminants, the degree of FA saturation of lipid sources will influence animal performance [ 3 ], milk composition [ 14 ] and milk FA profile [ 15 , 16 ]. In fact, in goat mammary epithelial cells, saturated and unsaturated long-chain FAs exert differential expression of genes related to lipid metabolism [ 17 ].…”

This study determined the effect of protected dietary oils on dry matter intake (DMI), digestibility and milk production in dairy goats. Nine Saanen goats were used in a 3 × 3 Latin square design with three periods of 25 days. A basal diet based on barley hay and corn silage was supplemented with 2.7% DM of calcium soaps of either palm (PO), canola (CO) or safflower (SO) oils. Data for dry matter intake, nutrient digestibility and milk production was analyzed using the general linear model (GLM) procedure of SAS. Gas production data was analyzed using the procedure of non-linear regression analysis (PROC NLIN) from SAS. Nutrient intakes were not affected by treatments. However, compared with CO, the digestibility of dry matter (653 vs. 552 and 588 g/kg), organic matter (663 vs. 559 and 606 g/kg) and neutral detergent fiber (616 vs. 460 and 510 g/kg) were lowered (p < 0.001) by SO and PO. Compared with CO, in vitro gas production increased (p < 0.001) in PO and SO (174 vs. 201 and 206 mL gas/g incubated DM). Compared with PO and CO, milk production increased (p < 0.001) with SO (0.88 and 0.95 vs. 1.10 kg/d, respectively). With regard to PO and SO, CO decreased fat (34 and 35 vs. 32 g/d) and protein (35 and 38 vs. 30 g/d) in milk. In conclusion, compared to the traditional use of calcium soaps manufactured from PO, protected SO resulted in increased milk yield without negative effects on digestibility and nutrient intake.

“…Algunos estudios (21,23) señalan que la suplementación de aceites vegetales mejora la producción de leche en ovejas y cabras debido a que aumenta el nivel de energía en la dieta. También se ha reportado que la inclusión de aceites vegetales en dietas formuladas isoenergética e isoprotéicamente provoca que se incluya un mayor nivel de forraje (24,25) . Lo anterior puede promover una interacción positiva entre el aceite vegetal adicionado y la mayor cantidad de forraje de las dietas para incrementar la producción de ácidos grasos volátiles, principalmente de acetato y butírico, los cuales se relacionan con una mejor secreción láctea en ovejas (14,26) .…”

El objetivo fue evaluar el efecto del nivel de inclusión de aceite de soya (AS) en la dieta pre-parto de ovejas de pelo sobre la producción y composición del calostro, desarrollo de las crías en los primeros 10 días postparto y la productividad de la oveja al parto. Un grupo de ovejas multíparas preñadas Katahdin x Pelibuey se asignaron a tres tratamientos (n=10), los cuales consistieron en dietas isoenergéticas e isoprotéicas que contenían: 0, 3 y 6 % de AS/kg de materia seca. Las dietas se ofrecieron del día 100 de gestación al parto. El peso y volumen del calostro aumentaron linealmente (P <0.05) conforme el nivel de AS en la dieta incrementó. El resto de las variables no presentaron efectos lineales ni cuadráticos (P >0.05) por nivel de AS. Entre ovejas alimentadas con y sin AS, o entre ovejas alimentadas con 3 y 6 % de AS, no se observaron diferencias (P>0.05) en peso vivo y condición corporal de las ovejas, así como en la composición del calostro, peso al nacimiento de las crías y el peso de camada al parto. Se concluye que la adición de 3 o 6 % de AS en la dieta preparto de ovejas de pelo no afectó la composición del calostro, el desarrollo de las crías ni la productividad de la oveja, pero sí afectó la producción de calostro, la cual fue mayor al nivel de 6 % de AS en la dieta. PALABRAS CLAVE: Ovejas preñadas, Nutrición materna, Aceite de soya, Producción de calostro. ABSTRACTThe objective was to evaluate the effect of the inclusion level of soybean oil (SBO) in the prepartum diet of hair ewes on the colostrum production and composition, development of lambs at d 10 post-lambing and ewe productivity at lambing. A group of pregnant multiparous ewes from Katahdin x Pelibuey genotype were assigned to three treatments (n=10), which consisted of isoenergetic and isoproteic diets containing: 0, 3 and 6 % of SBO/kg dry matter. Diets were offered from d 100 of gestation to lambing. The colostrum weight and volume increased linearly (P<0.05) as the SBO level in diet increased. The rest of variables did not show any linear or quadratic effect (P >0.05) as the SBO level changed from 0 to 6 %. Between ewes fed with or without SBO, or between ewes fed 3 and 6 % of SBO, no difference was detected (P >0.05) on live weight and body condition score of ewes, as well as on colostrum composition, lamb birth weight and litter weight at lambing. In conclusion, the addition of 3 or 6 % of SBO to prepartum diets of hair ewes did not affect the colostrum composition, the development of lambs or the ewe productivity, but affected the colostrum production, being greater when 6 % of SBO was used in the diet.
