Problems solved by technology

[0005] This would address two key issues that currently limit the industrial production of omega-3 HUFA-fortified meat products: (1) high production costs; and (2) taste and odor issues of the resulting meat products

Embodiment 1

[0044] This example illustrates the rate of omega-3 HUFA incorporation with a feeding regime of constant dietary omega-3 HUFA content.

[0045] 2240 broiler chickens were separated by sex at hatch and randomized to one of four feeding treatments. With the following concentrations: 0.09%, 0.27% and 0.45% by weight to three treatment groups (daily ration broiler broiler feed formulated according to NRC requirements (NRC, 1994)) fed dry Schizochytrium sp (17.5% DHA, with dry by weight) provides DHA (docosahexaenoic acid, C22:6n-3). The fourth group was the control group, where broiler broilers were rationed daily to meet NRC requirements but did not contain a source of DHA. The 560 broiler chickens in each feeding treatment group were further divided into 8 parallel experimental groups (n=70; 35 males, 35 females). Feed the chickens according to a standard 3-stage feeding schedule: initial chickens (0-21 days); growing chickens (22-42 days); and mature chickens (43-49 days). T...

Embodiment 2

[0048] This example illustrates the rate of omega-3 HUFA incorporation obtained with a feeding regime with variable omega-3 HUFA content.

[0049] 2500 broiler broilers (regardless of sex when arranged) were arranged in 50 pens for industrial production, 50 per pen. 10 columns were randomly assigned as the control treatment group, 8 columns were randomly assigned as one group, and 5 treatment groups. The treatments consisted of 5 varied feeding regimes, four of which provided broilers with a total of 3.6 g of DHA and one with a total of 5 g of DHA during the last 14 days of the broiler chicks' 49-day production cycle. The variable feeding rate treatments (% of total DHA fed on days 36-43 / % of total DHA fed on days 44-49) were as follows: 100% / 0% of total DHA 4g; 85% / 15%; 67% / 33 %; 50% / 50%; 67% / 33% of total DHA 5g. There was also a control group in which broiler chickens were not given any DHA in their daily diet. All formulations were industrially formulated broiler feeds t...

Abstract

A feeding regime for increasing the incorporation efficiency of omega-3 HUFAs in poultry meat is provided. Specifically, the poultry is fed a higher amount of omega-3 HUFAs in the late phase of poultry's production period than in the early phase.

Description

[0001] The technical field of the invention [0002] The present invention relates to a method for increasing the amount of omega-3 highly unsaturated fatty acids in poultry meat by feeding poultry a higher amount of omega-3 highly unsaturated fatty acids in the later stages of poultry production than in the earlier stages. Background technique [0003] Omega-3(n-3) highly unsaturated fatty acids (HUFAs) have been recognized as important dietary compounds for nourishing infants and mothers, maintaining normal cardiovascular and immune system health, and delaying the growth of tumor cells. The benefits of these fatty acids can be obtained by consuming fish several times a week or by consuming concentrated fish oil daily - a dietary source of omega-3 HUFAs. [0004] Efforts have been made to fortify poultry and pig meat with omega-3 HUFAs in order to provide consumers with additional dietary options for obtaining these nutritionally important fatty acids. It is known that the l...
