3 discuss
In poultry feed, can utilize phosphorus to should be 0.40～0.60%, and can only provide 0.1～0.2% utilized phosphorus in plant feed.For meeting in the animal body growth and development process the demand of phosphorus, usually in feed, add 1～3% high phosphorus feedstuff.So far still mainly use the raw materials such as calcium monohydrogen phosphate, bone meal.But the quality problems of calcium monohydrogen phosphate are more at present, are mainly the harmful element content overproofs such as fluorine, lead, arsenic, easily cause the poultry depauperation, and store in vivo, cause body poisoning, death.These harmful elements are discharged contaminated environment with ight soil, enter human body by approach such as grain, drinking-water again, damage.And also there are potential safety hazard in various degree in the restriction of the raw material sources of bone meal and sanitary index problem, some countries have forbidden that homology animal protein raw material is for animal and fowl fodder for this reason.Studies have shown that, the high phosphorus pollution on the environment is just more and more endangered and is being coerced the human lives.Pig fowl is limited in one's ability to utilizing of phytate phosphorus, in feed, unemployed phosphorus is directly excreted, enter water system with liquid dung, rainwater, the eutrophication that causes high phosphorus etc. in water system, make water plant, microbiological anomaly growth, ecological balance heavy damage in water, cause water pollution to go bad, foul, the water resource severe exacerbation, disruption of ecological balance etc.In recent years the red tide in lake, reservoir, coastal waters, red tide frequency and area are more and more higher, are exactly illustration.This is the Tough questions that the animal husbandry production development faces.
Simultaneously laying hen opens that Postpartum Diets forms and whether a day trophic level is rationally that the feeding quality quality is directly connected to the performance of production performance of layer chicken and the quality of egg quality, relation people's food security and the economic benefit of laying hen industry, can be described as the key point that poultry is produced, therefore must give enough attention.
Add the utilization rate that phytase improves phytate phosphorus in feed, thereby reduce the consumption reduction Feed Manufacturing cost of the phosphorus source forages such as calcium monohydrogen phosphate, bone meal, significantly reduce the pollution of phosphorus to environment, alleviate so that thoroughly stop fluorine poisoning of calcium monohydrogen phosphate etc.This result of the test shows, in the laying hen diet, adds phytase, can reduce by 50% left and right of calcium monohydrogen phosphate use amount, in conjunction with the use of probiotic, can obtain preferably laying hen production achievement.Lateral comparison, can make local poultry dealer obtain higher economic benefit, again can be from protection of the environment, and the angle of sustainable development, filter out the high-quality feed that meets local breeding environment.
Compare every performance in layers index and egg quality index between three test group and control group, the visible difference all not significantly (P>0.05) of respectively organizing, but the production performance index of three test group and egg quality are all a little more than control group, explanation is in this test under identical feeding and management condition, add phytase in the diet of three test group, reduce the consumption of Phos in feed formula simultaneously, can improve equally the biological effectiveness of phosphorus in egg feedstuff.Explanation again, the interpolation of phytase can bring economic benefit to production, can alleviate the immense pressure that the livestock and poultry breeding industry high phosphorus causes environment again, fundamentally protection of the environment sustainable development.
In addition, protein allowance is the principal element that affects laying rate and egg quality, and suitable protein level can obtain higher and lasting laying rate, egg size and protein content.In this test, the average egg production of three test group, average egg weight and protein content are all a little more than control group, in comparatively desirable state, the needs that three test group Different Dietary Protein Levels can meet the laying hen growth fully and produce are described, and can obtain larger economic well-being of workers and staff.
Quality of egg inferior is to cause laying hen one of the major reason of loss of already helping always, and the Major Nutrient that affects quality of egg have calcium, phosphorus, sodium, potassium, zinc, manganese, VD and VC etc.Calcium is the main component of eggshell, and in feed, during calcium deficiency, the thickness of eggshell and density reduce, so in the feed of laying hen, sufficient calcium should be arranged.Phosphorus be animal the essential and a kind of mineral element in close relations with the metabolism of calcium, in daily ration the phosphorus level not enough or with calcium in nonequilibrium condition, can reduce laying hen egg yield and eggshell quality, high levels of phosphorus is unfavorable for the absorption of calcium, also can reduce eggshell quality.Sodium, potassium, zinc, manganese, VD and VC reasonably can significantly improve quality of egg under scope.The shell thickness of three test group, density index are all than more excellent, and eggshell quality, in higher level, illustrate that the match ratio of calcium, phosphorus, sodium, potassium, zinc, manganese, VD and VC in three test group daily rations is more reasonable, and quality is higher.
