Description
Technical field
The present invention relates to a kind of agricultural university No. 3 joints grain small laying hens in brooding period compound premix.
Background technology
Agricultural university's No. 3 joints grain small laying hens is the layer breed that Wu often believes the Chinese oneself that academician, Yang Ning professor, professor Ning Zhonghua etc. cultivate.Because agricultural university's No. 3 joints grain small laying hens has advantages such as small, that feed consumption is few, egg product is good, No. 3 short and small breeding layer chicken persons of agricultural university have obtained than culturing the higher benefit of general goods laying hen.
Agricultural university's No. 3 joints grain small laying hens is compared with common laying hen, and have following characteristics: (1) bodily form small footprint size is few; The adult chicken body weight 1.60kg of agricultural university's No. 3 joints grain small laying hens, lighter by about 25% than common laying hen, its natural height is shorter about 10 centimetres than plain edition laying hen; (2) feed consumption is few, and feed conversion rate is high; The average daily ingestion amount of laying period agricultural university No. 3 joints grain small laying hens has only about 90g, lacks about 20% than common chicken, and feedstuff-egg ratio is generally at 2.1: 1, and high level can reach 2.0: 1, improves efficiency of feed utilization about 15% than common chicken; (3) premunition is stronger; Agricultural university's No. 3 joints grain small laying hens has stronger resistance to Marek's disease, and is also strong than common chicken to the resistance of general bacteriosis, so there is higher survival rate laying period; (4) a little less than docile, the ability of circling in the air of personality, manageability is fitted and is raised in cages and put in a suitable place to breed on ground such as forest land, orchard.
The common chicken of weight ratio of No. 3, agricultural university joint grain small laying hens is little, but neither be more little good more, and body weight is bigger slightly, and more favourable to keeping the peak of laying eggs.But; Physiological metabolism and the nutritional need of No. 3 short and small laying hens of agricultural university are different with the general goods laying hen; So to various nutrition such as forage protein, amino acid, vitamin, trace element need be different with the general goods laying hen, with general goods laying hen chick premix No. 3, the agricultural university joint grain small laying hens chick of feeding, be difficult to reach SBW; And the uniformity and survival rate are lower, have influenced the performance of laying period productive potentialities.
Summary of the invention
The purpose of this invention is to provide a kind of agricultural university No. 3 joints grain small laying hens in brooding period compound premix.
Agricultural university provided by the invention No. 3 joints grain small laying hens in brooding period compound premix is made up of following component: 27-33 mass parts DL-methionine, 18-22 mass parts lysine sulfate, 5.5-6.55 mass parts Choline Chloride, 1.125-1.245 mass parts aureomycin, 2.6-3.3 mass parts phytase, 0.4-0.6 mass parts anti-oxidant, 370-450 mass parts stone flour, 80-90 mass parts salt, 230-270 mass parts calcium monohydrogen phosphate, 221.5-77.7 mass parts medical stone, No. 3 joints of 25 mass parts agricultural universities No. 3 joints grain small laying hens chick composite trace element and 7 mass parts agricultural universities grain small laying hens chick B B-complex;
In every kilogram of said agricultural university No. 3 joints grain small laying hens chick composite trace element, contain 7.25-8.75g copper, 72-87.9g iron, 71.75-87.5g zinc, 71.87-87.77g manganese, 0.37-0.45g iodine, 0.31-0.37g selenium, all the other are carrier;
In every kilogram of said agricultural university No. 3 joints grain small laying hens chick B B-complex; Contain 4250-5300 ten thousand IU vitamin As (VA), 1000-1200 ten thousand IU cholecalciferols (VD3), 9-11 ten thousand IU vitamin Es (VE), 7-9g prokeyvit (VK3), 6.93-8.91g vitamin B1 (VB1), 25.6-30.4g vitamin B2 (VB2), 13.86-17.82g vitamin B6 (VB6), 0.07-0.09g cobalamin (VB12), 0.46-0.54g biotin, 128.7-158.4g nicotinic acid, 3.8-4.75g folic acid, 36-45g calcium pantothenate, 4.5-5.5g anti-oxidant, all the other are carrier.
The quality proportioning of above phytase is based on the phytase of 5000U/g, and during actual the use, the enzyme activity of the phytase that the addition of phytase can adopt according to reality converts.
In the said agricultural university No. 3 joints grain small laying hens chick composite trace element, carrier can be stone flour.
In the said agricultural university No. 3 joints grain small laying hens chick B B-complex, carrier can be corn protein powder.
The application of said agricultural university No. 3 joints grain small laying hens in brooding period compound premix in preparation agricultural university No. 3 joints grain small laying hens in brooding period daily ration also belongs to protection scope of the present invention.
The present invention also protects a kind of agricultural university No. 3 joints grain small laying hens in brooding period daily ration, it is characterized in that: said daily ration contains said agricultural university No. 3 joints grain small laying hens in brooding period compound premix.
Agricultural university provided by the invention No. 3 joints grain small laying hens in brooding period compound premix; Be to develop specially according to the physilogical characteristics and the nutritional need of agricultural university's No. 3 joints grain small laying hens; With strong points; Can satisfy the nutritional need of agricultural university No. 3 joints grain small laying hens chick better, feeding effect is obvious, and survivability of chicks is high, the body weight compliance rate is high, good evenness.The present invention has great economic worth for the breed of laying period agricultural university No. 3 joints grain small laying hens.
