Sow Nutrition

One hundred and two sows were fed either 2.0 kg/day (C–L) or ad libitum a control diet (C–H) or diets containing 10% added sucrose (SU) or 10% stabilized tallow (TA) from day 100 of gestation until parturition. Level of nutrient intake or source of energy in the sows’ diet did not significantly influence the number or weight of pigs born or the number of pigs weaned. The survival of pigs of less than 1.0 kg birthweight was significantly greater for sows fed the C–H diet. At weaning, pigs from sows fed the SU diet were significantly (P < 0.05) heavier than those from sows receiving the other three treatments. Pigs from the sows fed TA were heavier (P < 0.05) at weaning than those from sows fed C–L or C–H. There were no significant differences in the proximate composition of the colostrum from sows on any of the four treatments. Proximate carcass composition of the pigs at birth, 24 or 48 h of age was similar for pigs from all four sow treatments. The fatty acid content of the carcass lipid of the newborn pig was not significantly affected by sow feeding regimen. Carcass proximate analyses and fatty acid content of the carcass lipid were significantly (P < 0.01) affected by age of pig at slaughter.

Effect Of Light

Cyanobacteria are Gram negative prokaryotes that are capable of oxygenic photosynthesis. Although there are many similarities between eukaryotes and cyanobacteria in electron transfer and phosphorylation during photosynthesis, there are two features of the photosynthetic apparatus in cyanobacteria which distinguishes them from plants. Cyanobacteria contain phycobiliproteins organized in phycobilisomes on the surface of photosynthetic membrane. Another difference is in the organization of the photosynthetic membranes. Instead of stacked thylakolds within a chloroplast envelope membrane, as seen In eukaryotes, IntracytopIasmlc membranes generally are arranged in three to six concentric layers. Environmental factors such as temperature, nutrition and light fluency can significantly affect the physiology and morphology of cells. The effect of light Intensity shifts on the ultrastructure of Internal membrane in Anabaena variabilis grown under controlled environmental conditions was examined. Since a major constituent of cyanobacterial thylakolds are lipids, the fatty acid content also was measured and correlated with uItrastructural changes. The regulation of fatty acid synthesis in cyanobacteria ultimately can be studied if the fatty acid content can be manipulated.

Edible Insects

In the present paper we have determined the fatty acid content of some edible insects of Mexico. A comparative analysis of the insect species studied in this research showed that caproic acid was present in a minimal proportion which ranged between 0.01 for Periplaneta americana (nymphs) and 0.06 (g/100 g, dry basis) for Euschistus strenuus. The highest proportion of caprilic acid (0.09) was found in Tenebrio molitor (adults). Atta sp. had the highest amount of capric acid (0.26). Polistes sp. was found to be rich in lauric acid (0.77) and for myristic acid it had the highest content (5.64). Dactylopius sp. and E. strenuus were rich in palmitic acid (14.89). Euschistus taxcoensis had the highest quantity of palmitoleic acid (12.06). Llaveia axin exhibited the highest quantity of stearic acid (22.75). Polistes sp. was found to be rich in oleic acid (38.28). The highest quantity of linoleic acid was observed in T. molitor (larvae) (10.89), and in L. axin the highest content of linolenic acid (7.82) was obtained. A comparison between the species under the present investigation revealed that, in general, the insects are poor in caproic, caprilic, capric, lauric, myristic, palmitoleic and linolenic acids, because the quantities were either minimal or could not be detected at all. They had moderate quantities of stearic, palmitic and linoleic acids and had high quantities of oleic acid. Finally it was concluded that although a particular insect species is unable to fulfil the total fatty acid need for a human, if consumed in combination they could definitely be able to supply a good amount of this highly valued nutrient.
