Description:
METHOD FOR IMPROVING GROWTH PERFORMANCE AND/OR BONE PERFORMANCE OF ANIMAL

Technical Field

The invention is related to a method for improving growth performance and/or bone performance of an animal. In particularly, the invention is related to a method for improving growth performance and/or bone performance of an animal by administering to the animal 25-Hydroxy Vitamin D 3 and phytase.

Background of Invention

Phytase is a type of enzyme that catalyzes the hydrolysis of phytic acid, which is indigestible for organisms, to phosphorus which is digestible for organisms, including 3- phytase and 6-phytase. Phytase has been widely used as animal fee additive, which may increase use efficiency of- phosphorus in plant feed by 60%, and decrease phosphorus excreted from feces by 40%, so it is significantly useful to improve production benefit in livestock, agriculture and reduce pollution of phosphorus from phytic acid, (see US 3,297.548; Nelson T. S. et al, J Nutrition, 101; 1289- 1294, 1971; and Nelson T. S. et at, Poult Sci. 47: 1842- 1848, 1968)

25-Hydroxy Vitamin D :> has also been used widely as an animal feed additive. For example, US 2003/0170324 discloses a feed premix comprising 25-Hydroxy Vitamin D3 which may be added to poultry, swine, canine, or feline food; US 2005/0064018 discloses adding a combination of 25-Hydroxy Vitamin D 3 and vitamin D s to animal feed to improve swine 's bone strength; and US 5,695,794 discloses adding a combination of 25- Hydroxy Vitamin D 3 and vitamin D 3 to poultry feed to ameliorate the effects of tibial dyschondroplasia.

Surprisingly, the inventors of the invention found that a combination of 25-Hydroxy Vitamin D 3 and phytase can improve growth performance and/or bone performance of an animal and provide synergistic effect.

Content of Invention

Therefore, the invention provides a method for improving growth performance and/or bone performance of an animal, comprising administering to the animal an effective amount of 25-Hydroxy Vitamin D3 and phytase.

In the invention, the term "animal" includes al l animals including human. The examples of the animals include non-ruminants and ruminants. Ruminants include but are not limited to sheep, goat and cattle; and non-ruminants include but are not limited to horse; rabbit; pig including but not limited to infant pig, piglet, growing-fattening pig, sow and boar; and poultry such as turkey, duck and chicken (including but not limited to broiler chicken, egg-laying chicken) etc.. In the invention, the term "growth performance" means average daily weight gain (ADWG), average daily feed intake (ADFi) and/or feed conversion rate (FCR) of the animal.

In the invention, the term "bone performance " means fresh weight, length, radius, breaking strength, and/or bone mineral density (BMD), and/or ash, Ca and/or P contents of the bone of the animal .

According to the method of the invention, administration of 25-Hydroxy Vitamin and phytase to an animal can provide synergistic effects to improve growth performance and/or bone performance of the animal. The term "synergistic effect" means the phenomenon of 1+1>2, i.e., two or more substances mutually provide better effect than the summation of effects produced by each one of the substances, or the phenomenon of "mutually promotive effect", i.e., the effect produced by one substance is reinforced in the presence of the other substances.

In the invention, 25-Hydroxy Vitamin ¾ may come from any source, including commercial routes or direct synthesis. For example, 25-Hydroxy Vitamin D ? of the invention is synthesized according to the method described in US 4,310,467 and US

3,565,924.

In the invention, the phytase may be any type of phosphatase enzyme that catalyzes the hydrolysis of phytic acid (myo-inositol hexakisphosphate) and releases a usable form of inorganic phosphorus. The phytase of the invention may be 3-phytase, 6-phytase or a combination thereof.

The phytase of the invention may come from any source including plant and microbiological source, A preferable plant source for phytase is malt. Preferred microbiological sources for phytase are Aspergillus oryzae, Aspergillus niger, Aspergillus jieuum and Peniophora lycii, and the phytase from Aspergillus niger has been commercialized for use in animal feed. Phytase has also been isolated from E.coli, B. subtilis. and other thermostable microbes. Genes encoding phytase have been cloned from many microorganisms, and phytase can easily be produced and purified in industrial scale. Moreover, phytase can be genetically engineered such that it is more resistant to thermal, light, and/or chemical degradation. Examples of commercial phytase are Natuphos 5000 L, Natuphos™ 5000 G, Ronozyme® Hiphos M/L, etc.

A preferred phytase of the invention is 6-phytase (E.C, 3.1.3.26), preferably produced by a genetically modified strain Aspergillus oryzae (DSMZ 22-594).

The activity of phytase is measured in FTU units: 1 FTU (also-called FYT) is the amount of phytase that liberates 1 pmole phosphate per minute at pH 5.5 and 37°C.

The amount of 25-Hydroxy Vitamin Ό% and phytase for administration depends on the particular conditions of the animal. Usually, based on the body weight of the animal to be administered, 25-Hydroxy Vitamin D3 is administered in an amount of 0,2-20 Mg/kg body- weight per day, preferably 0.5- 15 μβ/kg body weight per day, more preferably

1-10 μgfkg body weight per day, even more preferably 1.5-5 μ§/な| body weight per day, and most preferably 2 μg/kg body weight per day; and the phytase is administered in an amount of 15- 150 FTU/kg body weight per day, preferably 20- 120 FTU/kg body weight per day, more preferably 30-100 FTU/kg body weight per day, even more preferably 50- 80 FTU/kg body weight per day, and most preferably 60 FTU/kg body weight per day.

The administration may be carried out once a day, or two or more times within one day to the animal. In addition, 25-Hydroxy Vitamin D 3 and phytase may be administered simultaneously, or separately and successively, for example, administered in an interval of 10 mins. 20 mins, 30 mins, 40 mins, 50 mins, 1 h, 2 h, 3 h or 4 h.

The 25-Hydroxy Vitamin D 3 and phytase may be directly administered to the animal as a feed composition, or as components of an animal feed or in drinking water of the animal.

Accordingly, in one embodiment, the invention provides use of a composition comprising 25-Hydroxy Vitamin D3 and phytase as an animal feed or feed additive.

Preferably, the animal feed or the animal feed with addition of the feed additive comprises 5-500 μΐ/kg, more preferably 10-300 .ug'kg, even more preferably 20-200 ^ig/kg, even more preferably 40- 100 pg/kg, and most preferably 50 ug ' kg of 25-Hydroxy Vitamin D 3 ; and 500-4000 FTU/kg, more preferably 800-3000 FTU/kg, even more preferably! 000-2500 FTU/kg, even more preferably 1 200-2000 FTU/kg, and most preferably 1500 FTU/kg of phytase *

Examples

Example 1

Piglets of an initial body weight of 7+0,5 kg were fed a basal diet ad libitum until 1O±0.5 kg. Groups of 8 piglets each were fed as follows:

A: basal diet, neither 25-Hydroxy Vitamin D3 nor 6-phytase was added;

B: basal diet + 50 ^ig/kg 25-Hydroxy Vitamin D ¾ and no 6-phytase was added;

C: basal diet + 1500 FTU/kg 6-phytase, and no 25-Hydroxy Vitamin D 3 was added;

D: basal diet + 50 μξ/kg 25-Hydroxy Vitamin D 3 + 1500 FTU/kg 6-phytase.

The formulation of the basal diet was as follows:

* Premix provide in 1000 g of the basal diet: VA. 6600 IU; VD 3> 2000 IU; VH. 50 IU; VK 3) 2 mg; VB ; , 4.5 mg; VB 2 , 8 mg; VB 6 , 6 mg; VB i 2 . 60 μ§; Niacin, 20 mg; pantothenicacid, 32 mg; Folic acid, 0.8 mg; Biotin, 0.23 mg; Choline, 750 mg; I ' e, 150 mg; Zn, 2340 mg; Cu. 120 mg; Mn, 50 mg; I, 0.6 mg; and Se, 0.3 mg

The 25-Hydroxy Vitamin D 3 used herein was obtained from DSM Nutritional Products Ltd.( Hy - DR. 1.25% Beadlet, Basel, Switzerland), and the 6-phytase used herein was also obtained from DSM Nutritional Products Ltd.(Ronozyme® Hiphos GT , Basel, Switzerland).

After the feeding term ended, the piglets were not fed for 12 hours and then weighed. Average daily weight gain (ADWG) during the term was calculated, average daily feed intake (ADFI) was calculated based on the feed weight before the feeding and rest feed weight: after the feeding, and feed conversion rate (FCR) was also calculated based on the average daily weight gain and average daily feed Intake (ADFI ADWG)). The experiment was run 6 times in parallel and averages were obtained as follows.

The data indicate that, compared with the piglets administered with neither

25-Hydroxy Vitamin D 3 nor 6-phytase or with any one of 25-Hydroxy Vitamin l>, and 6- phytase, the piglets administered with both 25-Hydroxy Vitamin D 3 and 6-phytase had quicker weight increase and lower FCR, so 25-Hydroxy Vitamin P 3 and 6-phytase had synergistic effect in improving growth performance of the piglets.

Example 2 Piglets of an initial body weight of 10±0.5 kg obtained from Example 1 were fed a basal diet ad libitum until 20±0.5 kg. Groups of 8 piglets each were fed as follows:

A: basal diet, neither 25-Hydroxy Vitamin D 3 nor 6-phytase was added;

C : basal diet + 1500 FTU/kg 6-phytase, and no 25-Hydroxy Vitamin D3 was added; D : basal diet + 50 .ug/kg 25-Hydroxy Vitamin D 3 + 1500 FTU/kg 6-phytase.

The formulation of the basal diet was as follows:

* Premix provide in 1000 g of the basal diet: VA, 6600 IU; VD 3 , 2000 IU; VE, 50 IU; VK 3 , 2 mg; VBj, 45 mg; VB 8 mg; VB 6 , 6 mg; VB 12 , 60 mi Niacin, 20 mg; pantothenicacid, 32 mg; Folic acid, 0.8 mg; Biotin, 0.23 mg; Choline, 750 mg; F ' e, 150 mg; Zn, 2340 mg; Cu, 120 mg; Mn, 50 mg: I, 0.6 mg; and Se, 0.3 mg

The used 25-Hydroxy Vitamin I>, was obtained from DSM Nutritional Products Ltd.( Hy

• DR. 1.25% Beadlet. Basel, Switzerland), and the used 6-phytase was also obtained from DSM Nutritional Products Ltd.(Ronozyme R Hiphos GT, Basel, Switzerland).

After the feeding term ended, the piglets were kept in limosis for 12 hours and then weighed. Average daily weight gain (ADWG) during the term was calculated, average daily feed intake (AD Ft) was calculated based on the feed weight before the feeding and rest feed weight after the feeding, and feed conversion rate (FCR) was also calculated based on the average daily weight gain and average daily feed intake (ADFI/ADWG). The experiment was run 6 times in parallel and averages were obtained as follows.

The above experimental data also indicate that the simultaneous administration of 25- Hydroxy Vitamin D : , and 6-phytase improved the weight gain and reduced FCR of the piglets and provided synergistic effects. Example 3

After the feeding of example 2 ended, fresh weight, length, radius, breaking strength, bone mineral density (BMD), and ash, Ca and P contents of the piglets ' femurs were measured as below:

Femur fresh weight: left femur was drawn out, muscles and hamstrings were stripped off to separate the femur (no injury of periosteum and cartilage cap), and then the femur fresh weight was measured.

Femur length: Femur length was measured by Vernier Caliper after the femur fresh weight was measured.

Femur radius: femur radius (cannon circumference of femur) was measured at a middle position after the femur fresh weight was measured.

Femur breaking strength: femur breaking strength was measured by Electronic Universal Material Mechanics Testing Machines (South China University of Technology, Guangzhou, China) to show the tibial strength. The span was set as 5 cm and the loading speed was set as 3 min/min. The bone was broken at a middle point. The sensor indicated the biggest force loaded during the breaking term, which was expressed as breaking strength (N).

Femur bone mineral density: femur bone mineral density was measured by Bone Densitometer SD-200 (Beijing Search Institute of Nuclear Industry, Beijing, China) with a radioactive source of low energy nuclides (241 Am). The bone for measuring (fresh sample) was positioned under the detector, and the driving device was started to synchronously move the radioactive source and detector. The amount of radiation penetrating through the bone was detected and bone mineral content (BMC, g/cm) per unit of length was calculated based on the permeation rate. Femur bone mineral density (BMD, g/cm 2 ) was calculated based on the scan length and the bone mineral content (BMC).

Femur ash content: After wrapped with filter papers, the femur was dipped in anhydrous ethanol for dehydration for 24 h and then extracted by ether for degrease for 24 h. After dried to constant weight at 100-105 °C, the dry weight of the dehydrated and degreased femur was recorded. Later, the femur was crushed, carbonized under low temperature until there was no smoke, transferred to a high temperature furnace for burning at 550 °C for 3 h, taken out into a drier for half an hour, and then weighed. It was put into the high temperature furnace for burning for 3 h, into a drier for cooling for half an hour, and then weighed again until the difference between two adjacent weighings was less than 1%. Finally, the ash content of the dehydrated and degreased femur was calculated by:

Ash Content (%) = [ash content after ashed(g)J / [dry weight of degreased bone before ashed (g)] x 100% Femur ash Ca content: measured by EDTA direct volumetric method (see China State Standard GB/T 6436-92).

Femur ash P content: measured by P-Mo-V acid colorimetric method (see China State

Standard GB/T6437-92).

Each group was measured twice and averages were obtained as follows:

The data indicate that, the administration of 25-Hydroxy Vitamin D ; and 6-phytase improved bone performance of the piglets. Special ly, the simultaneous administration of 25-Hydroxy Vitamin D 3 and 6-phytase provided synergistic effects in improving bone mineral density and breaking strength, and increasing Ca and P contents of the bone.

The above examples illustrate the invention without limitation. It should be understood that any person skilled in the art may make obvious amendments and modification to the invention, which should be covered within the protection scope of the present invention.
