A main reason for the rapid increase in organic food consumption is the perception that organic foods have a superior nutritional composition and/or convey health benefits. However, there is currently limited scientific knowledge about the effect of production systems on food composition. The study reported here compared fatty acid profiles and levels of fat soluble antioxidants in milk from or...

The nutritional status and proximate composition, fatty acid profile and mineral composition of milk from 26 wives of army personnel of low income group from Rawalpindi was investigated. The body mass index ranged from 13.5 to 23.7, hemoglobin from 8.6 to 14.8 G/dl, serum protein from 4.8 to 7.5 G and serum albumin from 3.3 to 4.8 G%. Milk protein content varied from 0.6 to 2.4%, fat from 1.0 t...

While a wealth of data on the fatty acid composition of mature human milk has been published, limited information is available on the quantities of individual fatty acids supplied to the suckling infant with maternal milk, through the whole first year of life. Our aim was to qualitatively and quantitatively evaluate the fatty acid composition of human milk from Italian mothers, throughout exten...

Trans fatty acids are suspected to be detrimental to health, particularly to cardiovascular function. Trans fatty acids include a wide range of fatty acids, with isomers of C18:1, conjugated and non-conjugated C18:2 as major components. A vaccenic acid (trans11-C18:1) + rumenic acid (cis9,trans11-CLA)-rich butter has been shown previously to exhibit health beneficial effects, but less is known ...

A total of 32 lactating Holstein cows with mean body weight of 622 kg (s.e. = 24) were allotted, at week 25 of lactation, to eight groups of four cows blocked for similar days in milk. The objective of the experiment was to determine the effect of feeding four dietary concentrations (0, 50, 100 or 150 g/kg of dry matter) of whole flaxseed, which contains the plant lignan precursor secoisolarici...

Inclusion of rapeseed feeds in dairy cow diets has the potential to reduce milk fat saturated fatty acid (SFA) and increase cis-monounsaturated fatty acid (cis-MUFA) content, but effectiveness may depend on the form in which the rapeseed is presented. Four mid-lactation Holstein dairy cows were allocated to four maize silage-based dietary treatments according to a 4 × 4 Latin Square design, wit...

evaluation of four safflower (carthamus tinctorius l.) genotypes for oil content and fatty acidcomposition showed that oil content varied from 22.16 to 34.39% and the highest seed oilcontent was obtained from isfahan14 genotype (34.39%, respectively). among those fatty acidswere detected, linoleic acid (75.81- 77.86%) was the predominant fatty acid followed by oleic(12.57–13.75%), palmitic (6.0...

This study was done to identify the effects of dietary safflower oil or soybean oil on the milk composition of maternal rats and the tissue fatty acid composition in postnatal rats. Different types of dietary fats affected the fatty acid pattern in the dam's milk. They affected tissue weight, lipid content, and phospholipid fatty acid compositions in the liver and brain of young rats, showing a...

The objective was to evaluate the effect of body condition score (BCS) at 30 days before calving (-30 days) induced by a differential nutritional management, parity and week of lactation (WOL) on milk yield and composition, and milk casein and fatty acid composition. Primiparous and multiparous Holstein cows with high BCS (PH, n = 13; MH, n = 9) and low BCS (PL, n = 9; ML = 8) under grazing con...
