Embodiment 1

[0477] Example 1: Effect of oxidatively transformed carotenoids on pig growth and feed conversion

[0478] The effects of oxidatively transformed carotenoids as food additives on growth and feed conversion were analyzed in 2 groups of 48 weaned pigs aged 18-21 days.

[0479] The first 48 pigs were randomized into 16 pens (3 pigs / pen) that were equally divided between two temperature-controlled rooms. All 24 pigs in one room were injected with an attenuated vaccine against porcine respiratory and reproductive syndrome (vaccination room) and the other 24 pigs were injected with a saline solution placebo (control room).

[0480] 2 pens / room were randomly assigned one of 4 feeds consisting of a mixture of oxidatively transformed β-carotene (OxBC) and a commercial pig feed.

[0481] OxBC was prepared as follows. A suspension of β-carotene in ethyl acetate was brought to oxygen saturation by bubbling oxygen through at room temperature while the mixture was stirred. After 8 days, ...

Embodiment 2

[0499] Example 2: Effect of oxidatively transformed carotenoids on growth behavior of broiler chickens

[0500] Upon arrival, a total of 1600 Ross x Ross 308 cockerels were assigned to treatment groups. There are 8 units in the study, each unit comprising 4 pens. The in-unit pens were randomly and evenly assigned to treatment groups (A, B, C, D). There were 50 birds per pen, and each pen within the unit contained birds of similar initial body weight. Using a randomized full unit design, the effects of the following four treatment groups in a randomized full unit design were studied:

[0501] Feed A (control): commercially available feed without OxBC

[0502] Feed B: commercial feed containing 0.0005% (w / w) OxBC

[0503] Feed C: commercial feed containing 0.001% (w / w) OxBC

[0504] Feed D: commercial feed containing 0.003% (w / w) OxBC

[0505] Treatment feeds were introduced on day 0 and continued until the end of the study on day 38. Chickens were given water ad libitum ...

Embodiment 3

[0517] Example 3: Optimizing study of pig dosage

[0518] A total of 240 pigs were assigned to treatment groups when weaned. Eight units were used in this study, each unit comprising 5 pens. One of the feeds (A, B, C, D or E) was randomly and evenly distributed among the pens of each unit. There are 6 pigs in each pen.

[0519] The following 5 feeds A-E used in the pig dosage optimization study contained OxBC at levels of 0, 0, 1, 2 and 5 mg / kg pig feed.

[0520] Feed A (control): commercially available feed without OxBC

[0521] Feed B (control): commercially available feed + drug without OxBC

[0522] Feed C: commercially available feed containing 0.0001% (w / w) OxBC

[0523] Feed D: commercial feed containing 0.0002% (w / w) OxBC

[0524] Feed E: commercially available feed containing 0.0005% (w / w) OxBC

[0525] Pigs were given feed and water ad libitum during the 35 day trial period. With the exception of treatment group B, which contained antibiotics, no medicated fe...

Abstract

The invention features compositions for administration of an oxidatively transformed carotenoid, fractionated oxidatively transformed carotenoid and components of oxidatively transformed carotenoid. The compositions are useful for supplementing the diet of an animal.

Description

Background of the invention [0001] The present invention relates to the use of carotenoid oxides as animal feed supplements. [0002] Animals raised under modern conditions optimized to promote growth are fed rations containing a high proportion of protein, usually in the form of soybean or cottonseed meal, and a high percentage of grains such as corn or milo, a type of sorghum . Feed additives that have been used include such hormones as diethylstilbestrol or DES which also increase the rate of weight gain, and tranquilizers to prevent illness or weight loss due to stressful closed environments. The practice of administering antibiotics to animals is almost universal, since it was found that adding small amounts of antibiotics such as penicillin, tetracycline and sulfamethazine to the feed enhanced the growth of pigs and cattle. Since feed is a relatively expensive cost factor (typically 50-70% of the cost) in animal food production, any improvement in the animal's ability ...
