milk performance (protein and fat content) and milk fatty acids (fa) profile of dairy cows under supplementation with two sources of concentrate, oilseeds (c, cottonseed) at two levels, low (5kg dm/cow/day) and high (7 kg dm/cow/day), and cereal grains (b, barley) at high rate (7 kg dm/cow/day), were studied in three herds (n=36) of spring calving holstein-friesian dairy cows (200 days in milk)...

Background and Objectives: In this study, the proteolysis and lipolysis of Poosti cheese produced from raw sheep milk in mountainous eastern regions of Iran were investigated during 90 days of ripening. Materials and Methods: Sodium dodecyl sulfate polyacrylamide gel electrophoresis for proteolysis (SDS-PAGE) and gas chromatography (GC) for free fatty acids (FFAs) were applied to investigate th...

The role of maternal colostrum to infant development has been extensively studied and presented. Among the main factors which contribute to breast milk composition are maternal diet, age and body mass index, parity, duration of pregnancy and stage of lactation. This study aims to investigate the potential impact of several factors including demographic (i.e. maternal age and nationality) on the...

the aim of this work was to analyze the fatty acid profile in persian gulf shrimp, metapenaeus affinis that is one of the edible and well-known shrimps and has suitable amount of fatty acids specific polyunsaturated fatty acids (pufa). it has been reported that, a high dietary consumption of marine n-3 fatty acids may prevent the development of atherosclerosis and thrombosis. the fatty acids pr...

Nutrients, lipids in particular, make up the central nervous system structure and play major functional roles: they stimulate development, migration, and nerve cell differentiation. They are part of gray matter, white matter, nerve nuclei, and synaptogenesis. Breast milk contains lipids which are crucial for infant brain development. The lipid profile of breast milk was used as a guideline for ...

Milk was collected from 20 primiparous Holstein cows that were distributed into four groups and arranged in a completely randomized design with a 35-day period to determine the effect of feeding fish oil, soybean oil, or their combination on milk production and composition. Experimental diets consisted of: 1) control diet; 2) a diet with 3% (DM basis) added fat from menhaden fish oil; 3) a diet...

Milk performance (protein and fat content) and milk fatty acids (FA) profile of dairy cows under supplementation with two sources of concentrate, oilseeds (C, cottonseed) at two levels, low (5kg DM/cow/day) and high (7 kg DM/cow/day), and cereal grains (B, barley) at high rate (7 kg DM/cow/day), were studied in three herds (n=36) of spring calving Holstein-Friesian dairy cows (200 days in milk)...

This study aimed to investigate the effect of sunflower seeds, either as whole or as oil, on rumen fermentation, milk production, milk composition and fatty acids profile in dairy goats. Fifteen lactating Damascus goats were divided randomly into three groups (n = 5) fed a basal diet of concentrate feed mixture and fresh Trifolium alexandrinum at 50:50 on dry matter basis (Control) in addition ...

Forty Holstein dairy cows receiving a 38% concentrate diet based on maize silage were assigned to either a control group, either a biotin group, receiving 20 mg of biotin per day from 15 days before expected calving date and for 120 days after calving. Milk production was measured daily, milk fat content, protein content, urea and somatic cell counts were determined weekly from week 2 to week 1...

Egg yolk oil is a natural source of bioactive compounds such as DHA, fat–soluble vitamins, lutein, phospholipids and cholesterol. These important compounds are also found in breast milk: DHA for infant brain development, lutein for eye health, vitamins A and E to support developing cells. Egg yolk oil naturally contains vitamin D which is required for a normal bone development. Fatty acid profi...
