Description
Technical Field
The invention relates to the technical field of broiler breeding and feed, in particular to a daily ration with high-dose folic acid for broiler breeding and application thereof.
Background
Folic acid is a water-soluble vitamin that must be extracted from feed during poultry growth. Folic acid plays an important physiological function in animal metabolism, is a coenzyme which cannot be deficient in fat metabolism, has important influence on amino acid metabolism and biosynthesis of protein and nucleic acid, and can reduce the content of Urea Nitrogen (UN) and reduce the negative effect caused by homocysteine. The recommended amount of folic acid for the daily ration of the broilers in the front NRC (1994) is 0.55mg/kg, and the recommended amount of the laying hens is 0.25-0.55 mg/kg; the recommended amount of folic acid of broiler chickens in national standard (2004) of China is 0.50-0.55 mg/kg, and the recommended amount of folic acid of laying hens is 0.25-0.55 mg/kg; in the recommendation of vitamin requirements of commercial Disemann company for poultry, the recommended amount of broiler chickens reaches 2-2.5 mg/kg, and the recommended amount of laying hens reaches 1-1.5 mg/kg. In the production of the broilers, breeders want to obtain higher production performance of the broilers, so that economic benefits are guaranteed, and therefore the improvement of the economic benefits of the broilers becomes a very concern for poultry breeders. Folic acid itself is used as a water-soluble vitamin and a carbon transfer body, and plays an important role in promoting the production performance of broiler chickens, so that the recommended amount of folic acid in NRC and domestic standards about poultry daily ration in the past is in accordance with the breeding background at the present stage, and the livestock breeding worker is worthy of consideration again.
Disclosure of Invention
The invention aims to provide a daily ration with high-dose folic acid for raising broilers and application thereof, so as to solve the problems in the background technology.
In order to achieve the purpose, the invention provides the following technical scheme that the daily ration with high-dose folic acid for raising the broiler chickens is characterized in that the growth and development of the broiler chickens are divided into two periods according to the weight of the broiler chickens, wherein the two periods are respectively 1-21 days old and 21-42 days old, the 1-21 days old are used for feeding the early-period daily ration, the 21-42 days old are used for feeding the later-period daily ration, the two periods are both corn bean pulp type daily rations, and the folic acid content of the corn bean pulp type daily ration is 13 mg/kg;
the early-stage daily ration fed for 1-21 days comprises the following components in percentage by mass: 50.12-70.32% of corn, 20-35% of 46 soybean meal, 3-12% of flour (third flour), 0.5-4% of 60 corn protein powder, 1-6% of 46 cottonseed meal, 1.39-3.63% of stone powder, 0.10-0.80% of L-threonine, 0.05-5% of DL-methionine and 2-6% of additive I;
the later-period daily ration fed for 21-42 days comprises the following components in percentage by mass: 52.94-73.18% of corn, 15-40% of 46 soybean meal, 5-16% of flour (third flour), 0.5-15% of 60 corn protein powder, 2-10% of 46 cottonseed meal, 1.58-6.58% of stone powder, 0.06-0.12% of L-threonine, 0.05-3.25% of DL-methionine and 2-8% of second additive;
the corn is dried and crushed.
The proportion of the corn, the soybean meal and the flour is 2:1: 5.
The ratio of the corn protein powder to the cottonseed meal to the stone powder is 1:2: 1.
The corn protein powder is obtained by performing multistage variable temperature extrusion on corn gluten meal.
The first additive comprises the following components in percentage by mass: 1.56 to 3.30 percent of calcium hydrophosphate, 0.24 to 0.63 percent of multi-vitamin and trace elements, 0.54 to 1.64 percent of L-lysine sulfate (70 percent), 0.84 to 3.22 percent of soybean oil, 0.30 to 1.20 percent of sodium chloride and 0.10 to 0.80 percent of choline chloride (60 percent).
The second additive comprises the following components in percentage by mass: 0.96-2.68 percent of calcium hydrophosphate, 0.24-0.63 percent of multi-vitamin and trace elements, 0.51-3.20 percent of L-lysine sulfate (70 percent), 3.51-7.20 percent of soybean oil, 0.30-1.20 percent of sodium chloride and 0.10-0.80 percent of choline chloride (60 percent).
An application method of a daily ration with high-dose folic acid for raising broilers comprises the following steps:
s1, selecting 196 broilers of 1 day old, randomly dividing the broilers into 2 types of treatment of a blank control group and a folic acid group, wherein each treatment is 7 in number of repetitions, and each repetition is 14 in number of repetitions;
s2, feeding normal diet to the blank control group, wherein the folic acid content is 1.3 mg/kg;
s3, feeding the folic acid group with an early-stage daily ration which is 10 times of the folic acid content of the treated group, wherein the folic acid content is 13 mg/kg; when the broiler grows to 21 days, feeding the folic acid group with later-period daily ration which is 10 times of the folic acid content of the treatment group;
s4, screening the broilers fed on the third day and weighing the broilers;
and S5, counting the production performance of the broilers fed on the 21 st day and the 42 th day.
Compared with the prior art, the invention has the beneficial effects that:
the addition of 13mg/kg folic acid in the commodity daily ration obviously increases the weight, daily feed intake and daily weight gain of the AA broiler at 21 days, reduces the feed-meat ratio, and meanwhile, the addition of 13mg/kg folic acid in the commodity daily ration obviously increases the weight, daily feed intake and daily weight gain at 42 days, but has no influence on the feed-meat ratio, so that the production performance of the broiler is improved under the condition of not influencing the health of the broiler, and the economic benefit is improved.

and S5, counting the production performance of the broilers fed on the 21 st day and the 42 th day.
The following data were obtained by performing the tests with reference to the examples:
according to the comparison of the tests, the addition of 13mg/kg folic acid in the commercial daily ration obviously increases the weight, daily feed intake and daily weight gain of the AA broiler at 21 days, reduces the feed-meat ratio, and meanwhile, the addition of 13mg/kg folic acid in the commercial daily ration obviously increases the weight, daily feed intake and daily weight gain of the AA broiler at 42 days, but has no influence on the feed-meat ratio.
