“…The total amount of USFA in BSFL is close to those in olive, or soya oils 65 . In particular, the concentration of lauric acid in BSFL-derived oil is considerably higher than in those derived from soybean, sunflower, and oil palm 66 . Lauric acid is known to react against lipid enveloped viruses, and many pathogenic bacteria and protozoa 67–69 .…”

In Africa, livestock production currently accounts for about 30% of the gross value of agricultural production. However, production is struggling to keep up with the demands of expanding human populations, the rise in urbanization and the associated shifts in diet habits. High costs of feed prevent the livestock sector from thriving and to meet the rising demand. Insects have been identified as potential alternatives to the conventionally used protein sources in livestock feed due to their rich nutrients content and the fact that they can be reared on organic side streams. Substrates derived from organic by-products are suitable for industrial large-scale production of insect meal. Thus, a holistic comparison of the nutritive value of Black Soldier Fly larvae (BSFL) reared on three different organic substrates, i.e. chicken manure (CM), brewers’ spent grain (SG) and kitchen waste (KW), was conducted. BSFL samples reared on every substrate were collected for chemical analysis after the feeding process. Five-hundred (500) neonatal BSFL were placed in 23 × 15 cm metallic trays on the respective substrates for a period of 3–4 weeks at 28 ± 2 °C and 65 ± 5% relative humidity. The larvae were harvested when the prepupal stage was reached using a 5 mm mesh size sieve. A sample of 200 grams prepupae was taken from each replicate and pooled for every substrate and then frozen at −20 °C for chemical analysis. Samples of BSFL and substrates were analyzed for dry matter (DM), crude protein (CP), ether extracts (EE), ash, acid detergent fibre (ADF), neutral detergent fibre (NDF), amino acids (AA), fatty acids (FA), vitamins, flavonoids, minerals and aflatoxins. The data were then subjected to analysis of variance (ANOVA) using general linear model procedure. BSFL differed in terms of nutrient composition depending on the organic substrates they were reared on. CP, EE, minerals, amino acids, ADF and NDF but not vitamins were affected by the different rearing substrates. BSFL fed on different substrates exhibited different accumulation patterns of minerals, with CM resulting in the largest turnover of minerals. Low concentrations of heavy metals (cadmium and lead) were detected in the BSFL, but no traces of aflatoxins were found. In conclusion, it is possible to take advantage of the readily available organic waste streams in Kenya to produce nutrient-rich BSFL-derived feed.

This study aimed to investigate the effect of a virgin flaxseed oil (FO) rich in n − 3 polyunsaturated fatty acid, supplemented or not with a bioactive supplement (BS) containing tocopherols and phytosterols on the prevention of nonalcoholic fatty liver disease in a high‐fat (HF) animal model. Male Wistar rats were fed 60 days with a recommended (SO7, soybean oil 7%) or an HF diet (fat, 30%) containing soybean (SO30), corn (CO30), or FO (FO30) or the same oils supplemented with 1% of BS (SO30BS, CO30BS, or FO30BS, respectively). Hepatic and dietary FA composition, triacylglycerides (TAGs) content in serum and liver, nutritional parameters, in vivo TAG‐secretion rate, liver histology, mRNA levels of β‐oxidation‐related genes, and carnitine palmitoyl transferase‐1a (CPT‐1a) enzyme activity were determined. At HF levels, FO30 and FO30BS groups showed the highest total n − 3 PUFA levels in diets and were associated with lower weight gain, liver TAG content, and microsteatosis degree. The CPT‐1a activity was enhanced in FO30 and FO30BS, showing differences only by the type of dietary oil. The BS supplementation induced an increase in the β‐oxidation‐related gene expression. Virgin FO prevented liver steatosis and hepatomegaly induced by HF diets. The BS supplementation reduced body fat accumulation and enhanced expression of β‐oxidation related genes, without affecting hepatic TAG content.Practical Applications: Scientific knowledge of functional lipids with high oxidative stability and biological activity has great practical application in reducing non‐communicable chronic diseases. This study provides evidence on the potential synergic and complementary effects of virgin FO, TP, and PS to be used for the prevention of the metabolic hepatic disorders involved during the evolution of the different steps of NAFLD. Specifically, based on different biological mechanisms, this stable combination of bioactive lipids could prevent not only the development of exacerbated hepatic TAG accumulation but also the hepatocellular injury seen at different stages from hepatic steatosis to steatohepatitis.

“…En cada día de muestreo y para cada muestra de tanque (100 mL) se separaron 20 mL para las determinaciones de composición química (grasa butirosa, proteína, lactosa, sólidos totales y sólidos no grasos) en el Laboratorio de Calidad de Leche del Instituto Nacional de Investigación Agropecuaria (INIA). Los 80 mL restantes fueron inmediatamente congelados (-20 °C) para el ulterior análisis del perfil en AG por cromatografía gas-líquido (GLC), según se describe en Masson et al (2015). Las diferencias de composición de leche y perfil de AG entre lotes (LE vs LCLA) fueron analizadas a través del test T de Student para observaciones independientes.…”

ResumenEl objetivo del trabajo fue reducir la presencia de los ácidos grasos (AG) saturados potencialmente aterogénicos (C12:0, C14:0 y C16:0) de la leche y aumentar la presencia del ácido linoleico conjugado (CLA) en vacas lecheras estabuladas alimentadas con ración completamente mezclada (RCM) a través del aporte suplementario de ácidos grasos poliinsaturados (AGPI). Se utilizaron dos lotes de 70 vacas multíparas en el primer tercio de lactancia. Luego de seis semanas experimentales y durante cinco días consecutivos se obtuvieron cinco muestras de leche estándar (LE) provenientes del tanque colector del lote vacas sin AGPI suplementarios, y cinco muestras de leche CLA (LCLA) provenientes del tanque de las vacas suplementadas con los AGPI. El tenor graso (g/100g) de la LE (3,84) resultó superior (p<0,001) al de LCLA (2,84) por reducción (17,21%) de los AG potencialmente aterogéni-cos. El índice aterogénico fue mayor (p<0,001) en la LE (4,07) comparado al de la LCLA (2,58). La concentración del CLA aumentó (p<0,001) un 122% en LCLA (0,77 g/100 g) respecto al valor registrado en LE (0,34 g/100 g). El ácido oleico (g/100 g) resultó superior (p<0,001) en la LCLA (23,37) comparado con la LE (18,78). El aporte suplementario de AGPI permitió incrementar el valor saludable de la leche producida en un sistema de alimentación estabulado manteniendo una adecuada relación (6,59) omega-6/omega-3 en la leche y confirmando la plasticidad en la composición de los AG constitutivos de la grasa láctea. Palabras clave: Vaca lechera, alimentación estabulada, perfil de la grasa láctea. AbstractThe aim of the work was to reduce the presence of the potentially atherogenic fatty acids (FA) of milk (C12: 0, C14: 0 and C16: 0) and increase the presence of conjugated linoleic acid (CLA) in confined dairy cows fed a total mixed ration (TMR) supplemented with polyunsaturated fatty acids (PUFA). Two batches of 70 multiparous cows in the first third of lactation were used. After six experimental weeks and for five consecutive days, milk samples (5) were obtained from the collector tank of non-supplemented cows (LE) and of CLA milk (LCLA) from the tank of PUFA supplemented cows. Fat content (g/100g) in LE (3,84) was higher (p<0,001) than LCLA (2,84) explained by a significant reduction (17,21%) in the concentration of the potentially atherogenic FA of milk. The milk atherogenic index was higher (p<0,001) in LE (4,07) compared to LCLA (2,58). Milk CLA content increased (p<0,001) by 122% in LCLA (0,77 g/100 g FA) compared to LE (0,34 g/100 g FA). Oleic acid concentration (g/100 g FA) resulted higher (p<0,001) in LCLA (23,37) compared to LE (18,78). Supplementation with PUFA in confined dairy cows increased the healthy value of the milk produced maintaining an adequate omega-6/omega-3 ratio (6,59) and confirmed the plasticity in milk fatty acid composition.
