Fatty Acid Composition Analysis

The purpose of this study was to evaluate the off odor in the meat of Alabio, Cihateup and cross-bred of both on the second generation. There were 36 ducks consisting 8 Cihateup Ducks, 9 alabio ducks and 19 cross-bred ducks. These ducks were reared for 10 weeks and fed by commercial feed containing 21-23% protein and 2900-3000 kcal/kg metabolic energy as much as 125 g/head/day. Ducks were put in colonies in box sized 1m x1 m. The off odor intensity, degree of liking and fatty acid composition of chest and thighs meat from Cihateup Duck, Alabio Duck and their crossbreeding were determined. Therefore, off odor intensity was analyzed using the rating intensity. Degree of liking was performed by hedonic ratio fatty acid composition analysis which was conducted by Gas Chromatography (GC). The off odor intensity of commercial meet of Alabio, Cihateup and their crossbreeding were not significantly different. Degree of aroma liking among Alabio, Cihateup and their crossbreeding meat was significantly different in breast commercial cutting where their cross breeding meat had the highest degree of liking. Ratio of unsaturated fatty acid to saturated fatty acid of meat from crossbreeding duck was lower than the one from the ancestor.Keyword: sensory, duck meat, Alabio, Cihateup, cross-breed

Composition Analysis

Physical properties of commonly grown Sri Lanka groundnuts cultivars and promising accession varied considerably and numbers of kernels, pod beak, reticulation, testa colour, and shell out percentage have differences among groundnuts. However, they showed more similarities for most of the characters. Moisture (5.4-8.4%), crude protein (18.7-28.5%), lipid (43.4-53.0%), ash (4.4-5.8%), carbohydrates (9.3-18.2%) and energy level (565.7-618.2kcal) contents varied considerably. Quality and flavor of edible groundnuts and its products are affected by fatty acid composition of oil. Lipids were mainly composed of mono and polyunsaturated fatty acids (>78% of the total lipids). Fatty acid composition analysis indicated that oleic acid (C18:1) was the main constituent of monounsaturated lipids in all seed samples. With the exception of ANKG1, linoleic acid (C18:2) was the major polyunsaturated fatty acid. The saturated fatty acids (Palmatic, Stearic acid and behenic acid) in different cultivars ranged between 10.2 to 15.6%, 2.5 to 6.3% and 1.1 to 5.3%, respectively. Differences among cultivars for oleic acid exhibited significance which ranged between 38.2 to 47.4%. Similarly, cultivars differed statistically for linoleic acid which showed a range of 23.1 to 38.7%. Oleic to linoleic acid ratio was differed and all the released varieties were below the minimum standard level of 1.6, whereas ICGV 86590 and ICGV 00073 showed higher O/L ratio of 1.94 and 1.75 respectively.

Significant Difference

This study aimed to evaluate the fatty acid composition of zebrafish fed diets containing linseed oil compared to sunflower oil. First, diets supplemented with linseed and sunflower were formulated, fish were fed for 40 days, and their parts collected for analysis. Diet composition analysis, extraction and derivatization of fatty acids, gas chromatography analysis, RNA extraction and cDNA synthesis, quantitative real-time polymerase chain reaction (qRT-PCR, and statistical analyses were performed. Linseed oil exhibited an omega-3 rich lipid profile. 18:3n-3 content incorporated into the muscle tissue of fish fed linseed oil was 50% higher than that fed sunflower oil. This higher amount of 18:3n-3 favored the production of 20:5n-3 and 22:6n-3 fatty acids by synthetic pathways in the organism since these fatty acids were not initially found in the oil composition. Furthermore, in all analyzed parts of zebrafish that were fed linseed oil, concentration of 20:4n-6 were lower, while 20:5n-3 and 22:6n-3 were higher compared to the same parts fed with sunflower oil. PCR expression assay showed no significant difference, indicating that linseed oil diet was not harmful. Thus, this work evidenced that synthesis of essential fatty acids, primarily omega-3 fatty acids, was greater in zebrafish upon consumption of diets supplemented with linseed oil.

Milking Frequency

It has been well established that milk yield is affected both by milking frequency and due to the removal of residual milk, but the influence of a combination of these factors is unclear. In this study, four mid-lactation cows were used in a 4 × 4 Latin square design to test the hypothesis that the effects of more frequent milking and residual milk removal on milk yield and composition are additive and alter milk fatty acid composition. Treatments comprised two or four times daily milking in combination with (or without) residual milk removal over a 96 h interval preceded by a 2 d pretreatment period and followed by a 8 d washout in each 14 d experimental period. Milk was sampled at each milking for the analysis of gross composition and SCC. Samples of available and residual milk collected on the last milking during each treatment period were collected and submitted for fatty acid composition analysis. Increases in milking frequency and residual milk removal alone or in combination had no effect on milk yield or on the secretion of lactose and protein in milk. However, residual milk removal during more frequent milking increased milk fat yield. Milking treatments had no major influence on the fatty acid composition of available milk, but resulted in rather small changes in the relative abundance of specific fatty acids, with no evidence that the additive effects of treatments were due to higher utilisation of preformed fatty acids relative to fatty acid synthesis de novo. For all treatments, fat composition of available and residual milk was rather similar indicating a highly uniform fatty acid composition of milk fat within the mammary gland.
