the oil extracted from three major canola cultivars (hyolla401, hyolla420 and rgs003) grown in golestan province was analyzed for physico-chemical properties, fatty acid composition, minerals content, and stability during 16 weeks of storage. according to the results, the highest iodine value and refractive index belonged to hyolla401. the highest saponification value was observed in hyolla420....

olive oil in general due to it monounsaturation, stability, nutritive value, consistency, taste andaroma might be considered as a valuable and luxury oil. annual importation of olive oil to iran frommediterranean countries is on a large scale although some olive oils are produced in iran particularly in the northand some plantation has been applied in different provinces particularly in fars. t...

The objectives were to study the effects of feeding rolled flaxseed (FLX) to early-lactation dairy cows on milk yield, milk components, and milk fatty acid profiles as well as on measures of cow reproduction. Lactating Holstein cows, on 3 commercial dairies, were fed either an early-lactation ration (CON) or a ration that was similar in protein, energy, and fat content but that included FLX (0....

Triacylglycerols (TG) of rat milk supply about two-thirds of the energy consumed by suckling rat pups. The present studies were undertaken to determine stereospecific fatty acid composition and molecular species distribution of milk TG and TG produced during digestion, transported in lymph and blood, and present in the liver of 9-- 10-day-old pups. Results support non-random stereochemical fatt...

To determine the effect of alkaline hydrogen peroxide treatment of whole canola seed on milk fatty acid composition, 12 multiparous lactating Holstein cows (618 kg, 47 d in milk) were fed total mixed rations in a replicated (3) 4 x 4 Latin square designed experiment. The control diet contained no supplemental fat source. Canola seed (11.2%), either crushed or treated with alkaline hydrogen pero...

The objective of this study was to evaluate the utilization of different sources of unsaturated long-chain fatty acids in diets for dairy cows during the transition period and early lactation on the milk fatty acid profile and composition of the protein fraction. Thirty-six Holstein cows were divided into three groups, fed the following diets: control (C); soybean oil (SO); and calcium salts of...

Dietary macro and micro nutrients in their respective proportion and fractions present a practical potential tool to fabricate milk constituents since cells of lactating mammary glands obtain about 80 % of milk synthesis nutrients from blood, reflecting the existence of an isotonic equilibrium between blood and milk. Diverting milk biosynthetic activities through manipulation of nutrients towar...

OBJECTIVES The purpose of this study was to investigate what effect the ingestion of sardines, rich in omega-3 series polyunsaturated fatty acids, has on the composition of breastmilk. METHODS This was a prospective study of 31 nursing mothers under observation at the Hospital Guilherme Alvaro. Each was given 2 kg of fresh sardines twice with a 15-day interval. Milk was sampled and a 24-hour ...
