“…The differences found in the PUFA compositions among the organs after maternal supplementation may be derived from the differential tissue expression of the elongase-2 enzyme, which is vital for the final conversion of EPA to DHA [ 40 ]. Although organs such as the brain or liver also showed an increase in n3-PUFA concentration in group T, muscle was the tissue with the more prominent difference between treatments, in accordance with previous studies [ 41 ]. Litter size also had important implications in the n3-PUFA concentrations, as it was highly related to the treatment group.…”

“…Sex also had important effects on the n3-PUFA accumulation. Previous studies have shown that maternal supplementation has different implications for males and females in swine [ 16 , 41 ], with offspring showing different metabolic adaptations depending on their sex [ 42 ], so the diet restriction given in the present experiment could have reinforced the differences between males and females regarding n3-PUFA accumulation. There are sex-specific differences in essential n-3 essential fatty acid metabolism [ 43 ].…”

Intrauterine Growth Restriction (IUGR) is a major problem in pig production and different strategies, mainly maternal supplementation with different agents, are currently being studied. The combination of hydroxytyrosol and n3-PUFA seems to be a promising treatment to counteract IUGR, since the combination may help improve n3-PUFA composition and lower the inflammatory status of IUGR piglets. The aim of the present study is to determine the effects of a maternal supplementation, from day 35 to day 100 of pregnancy, with linseed oil and hydroxytyrosol on the fetal FA composition. The results showed higher n3 levels, including eicosapentaenoic and docosahexaenoic FA in the offspring from treated gilts, which showed lower n6-PUFA/n3-PUFA (n6/n3) ratios. Saturated and monounsaturated fatty acids were also affected by treatment, especially in the muscle and brain. Thus, a maternal supplementation with linseed oil and hydroxytyrosol affected the fetal FA tissue composition, which could have implications in pig production due to the improvement of the piglets’ health status.

“…Spirulina is an edible blue-green filamentous, spiral-shaped microalga of the cyanobacteria phylum and is therefore an autotrophic prokaryote [9,38]. It is naturally present in the alkaline lakes of Mexico and Africa, where it has historically been a source of food for the ancient inhabitants of those places [7].…”

The search for alternative protein sources to soybean meal (SBM) in animal feeding is a strategic objective to reduce production costs and contribute to sustainable animal production. Spirulina, due to the high protein content, has emerged as a potential cost-effective, sustainable, viable, and high-nutritional-value food resource for many animal species. Insect larvae (Tenebrio molitor and Hermetia illucens) are also considered potential alternatives to SBM, given their high edible percentage of almost 100%, as well as a protein value higher than that of vegetable proteins. Rapeseed meal and grain legumes, such as fava beans, peas, lupins, and chickpea, can also be used as locally producible protein ingredients. This study reviews the nutritional value of these potential alternatives to SBM in pig diets, and their effects on animal performance, digestion, immune system, and the physicochemical and sensorial characteristics of meat, including processed pork products. The limits on their use in pig feeding are also reviewed to indicate gaps to be filled in future research on the supplementation level of these potential alternative protein sources in pig diets.

A CMOS Algae Growth Period Monitor for Algaculture Applications

et al. 2022

View full text Add to dashboard Cite

In this work, a complementary metal-oxidesemiconductor (CMOS) algae growth period monitor is newly investigated for algaculture applications. The proposed monitor includes an algae sensor and a CMOS converter. The proposed monitor can transform the algae growth period into a duty cycle linearly. Through the duty cycle of the proposed CMOS converter, the algae growth status could be easily and quickly obtained. In addition, in order to be adaptively utilized in different kinds of algae growth environments, the proposed CMOS converter has a wide differential rail-to-rail voltage to the current converter and the adjustment sensitivity circuits. The measured wide-range differential rail-to-rail voltage of the CMOS converter was from −1.5 to 1.5 V, and the range of output duty cycle corresponded from 1.04% to 99.3%. The sensitivities could be varied to 41.21%/V, 32.8%/V, 27.38%/V, and 23.5%/V, respectively. The measured range of algae growth period was 1 to 5.5 days, and the range of output duty cycle was 24.96%-90.19% under different concentrations of algae nutrients (0.6‰, 0.8‰, and 1‰). A 0.49% of the measured maximum linear error was obtained. Lastly, two types of algae (Nannochloropsis sp. and Isochrysis galbana) were experimented. Convinced by the measurements and experiments, the proposed CMOS algae growth period monitor had correct functionalities for algaculture applications.
