Benefits of technology

This patent is about a feed additive composition that can help prevent necrotic enteritis, a disease that affects livestock. The additive contains a combination of different enzymes and a specific type of sugar called DFMs. The enzymes break down the phytate in cereals and legumes, which reduces the amount of nutrients that harmful bacteria can absorb. The DFMs also inhibit the growth of harmful bacteria and improve the animal's resistance to the disease. The combination of the enzymes and DFMs is more effective than using either alone in reducing the amount of harmful bacteria. This makes the feed additive a useful tool for preventing necrotic enteritis and improving animal health.

Problems solved by technology

Although combinations of DFMs with some enzymes have been contemplated, the interaction between DFMs and enzyme has never been fully understood.

Materials and Methods

[0440]Three thousand six hundred one-day-old Cobb male chicks were purchased from a commercial hatchery. At study initiation, fifty males were allocated to each treatment pen by blocks. The study consisted of the following treatments (Table 1):

Materials and Methods

[0451]Cobb 500 male broiler chicks were obtained from a commercial hatchery. A total of 26 chicks were randomly assigned to one of 8 replicate pens per treatment. Floor pens (16 ft2 / pen) were located in a curtain-sided house containing controlled heating, circulating fans, heat lamps and fresh wood shavings. Birds were exposed to fluorescent lighting in a 24 h light cycle for the first four days and then 16 light:8 hour dark cycle for the remainder of the experiment. Feed was provided in bell feeders and water supplied via nipple drinkers ad libitum. A 5× dose of Coccivac-B (Intervet) was administered manually with a syringe into the oral cavity of chicks at one day of age.

Materials and Methods

[0459]One digestibility trial with broiler chickens was conducted to determine the effects of dietary enzymes and DFMs treatments on nutrient utilisation. The cages were housed in environmentally controlled rooms. The birds received 20-hour fluorescent illumination and, allowed free access to the diets and water. On day 1, a broiler live coccidiosis vaccine was given to all chicks via drinking water. Paper was provided on cage wire-floor for the first three days to enable recycling of Eimeria Oocystes. The study consisted of the following treatments (Table 5).

Abstract

A feed additive composition comprising a direct fed microbial in combination with a protease, a xylanase, an amylase and a phytase, and a method for improving the performance of a subject or for improving digestibility of a raw material in a feed (e.g. nutrient digestibility, such as amino acid digestibility), or for improving nitrogen retention, or for avoiding the negative effects of necrotic enteritis or for improving feed conversion ratio (FCR) or for improving weight gain in a subject or for improving feed efficiency in a subject or for modulating (e.g. improving) the immune response of the subject or for promoting the growth of beneficial bacteria in the gastrointestinal tract of a subject, which method comprising administering to a subject a direct fed microbial in combination with a protease, a xylanase, an amylase and a phytase.

Description

FIELD OF INVENTION[0001]The present invention relates to methods for improving feed compositions using a direct fed microbial in combination with a specific combination of enzymes, and to a feed additive composition comprising a direct fed microbial in combination with a specific combination of enzymes. The present invention further relates to uses and kits.BACKGROUND OF THE INVENTION[0002]Supplemental enzymes are used as additives to animal feed, particularly poultry and swine feeds, as a means to improve nutrient utilization and production performance characteristics. Enzyme blends are available to improve the nutritional value of diets containing soybean meal, animal protein meals, or high fibre food by-products.[0003]The concept of direct fed microbials (DFM) involves the feeding of beneficial microbes to animals, such as dairy cattle when they are under periods of stress (disease, ration changes, environmental or production challenges). Probiotics is another term for this categ...
