Benefits of technology

The present invention is about a feed composition for animals that contains tea tree oil as an effective antimicrobial agent. The inventors found that animals maintained on a diet supplemented with tea tree oil showed no difference in their feed consumption, weight gain, and gut microbial profiles when compared to animals fed on a standard antibiotic. The tea tree oil supplemented diet also protected the animals in a disease challenge trial involving Salmonella sofia. The invention provides a method of protecting animals from bacterial infection by feeding them a diet containing tea tree oil. The tea tree oil may be encapsulated by an encapsulating agent to decrease its volatility and loss during manufacturing and storage. Overall, the invention maintains the health and growth of animals and provides a natural and effective way to protect them from bacterial infection.

Problems solved by technology

This resistance portends a serious challenge to the treatment of sick birds as well as humans.
A range of products have been tested as alternatives to antibiotics, but to date, no single product has been identified that completely fits the role.

Effects on Productivity of Broiler Chickens when Tea Tree Oil is Added to Chicken Feed

1.1—Experimental Protocol

1.1.1 Birds and Management

[0126]Three hundred and thirty-six mixed-sex chicks (initial weight, 39.8±0.66 g) were randomly allocated to 7 treatments of 6 replicates (8 birds per replicate). The seven treatments were a negative control diet, a positive control containing zinc bacitracin (50 ppm), and the same diet supplemented with tea tree oil (TTO) at 2, 4, 8, 16 or 32 mg / kg diet during the starter phase (1-21 days), or 3, 6, 12, 24 or 48 mg / kg diet in the finisher phase (22-35 days). These diets were designated NC, ZnB, L1, L2, M, H1 and H2, respectively. For the first three weeks, the birds were reared in brooder cages (600×420×230 cm) with a wire floor in environmentally controlled experimental rooms. The temperature was set at 33° C. for the first three days and gradually reduced to 24° C. at 21 d of age. At 21 days, the birds were transferred to larger battery cages (8...

Gut Microbial Profiles of Broiler Chickens on Diets Supplemented with Tea Tree Oil

2.1—Experimental Protocol

2.1.1 Birds and Management

[0140]Three hundred and thirty-six mixed-sex chicks (initial weight, 39.9±0.73 g) were also used in this study, mainly to investigate changes in intestinal microbial profiles. The experimental design was exactly as described for Experiment 1, except that the chicks were sexed before allocation to the treatment groups. Each replicate contained five females and three males. During sample collection for assessment of early organ development on day 7, only female birds (one per replicate) were chosen; at 21 days, two females and a male were chosen per replicate, and the remaining birds (usually 2 of each sex) were slaughtered at 35 days of age. Samples were collected at days 21 and 35 principally for the assessment of intestinal microbial profiles and short-chain fatty acids (SCFAs), although gross changes (feed consumption, weight gain and nutrient digest...

Testing the Prophylactic Potential of Tea Tree Oil Against Development of Necrotic Enteritis in Broiler Chickens

3.1—Experimental Protocol

3.1.1 Birds and Management

[0152]This experiment was of semi-commercial scale, designed to test response to disease (Salmonella sofia) challenge. Nine hundred mixed-sex chicks (initial weight, 47.7±1.06 g) were involved and these were randomly divided into six groups; a negative unchallenged group (NC), negative challenged (NCC), Zn-bacitracin challenged (ZnB), low TTO challenged (LTTO), mid TTO challenged (MTTO) and high TTO challenged (HTTO). The corresponding amounts of TTO used for LTTO, MTTO and HTTO, respectively were 2, 8 and 16 mg / kg diet during the starter phase (1-21 days), and 3, 12 and 24 mg / kg diet in the finisher phase. Each of the 6 treatments was allocated to 6 single pen replicates, each containing 25 (13 male and 12 female) birds at 1 day of age. All pen group weights were within 6% of the mean pen group weight.

Abstract

The present invention relates to a feed composition for an animal comprising tea tree oil, wherein the tea tree oil is present in an amount sufficient to reduce bacterial infection in the animal upon ingestion of the feed composition, and to methods for preparing such a composition.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a feed composition for animals, particularly poultry, including tea tree oil as a supplement that reduces bacterial infection in the animals. The present invention also relates to a method of protecting animals from bacterial infections by feeding a diet comprising tea tree oil to those animals. The present invention further relates to a method of preparing the feed composition to deliver tea tree oil to the animals.BACKGROUND[0002]Antibiotics have been used as supplements in diets for poultry for many years and in many parts of the world. Microbial species, some of them potential pathogens, have developed resistance to a range of antibiotics that have been used in diets for over five decades. This resistance portends a serious challenge to the treatment of sick birds as well as humans. A range of products have been tested as alternatives to antibiotics, but to date, no single product has been identified that completely fi...
