Control group
The compound premix feed for the laying hens in the young period of the control group is fed for 10 weeks according to the use instruction of the feed of the control group, and the growth state of the laying hens is recorded.
Design of experiments on the production conditions of the layer in the young period
Selecting 800 healthy young-period laying hens of 1 week old, and randomly dividing the 800 young-period laying hens into 4 treatment groups, wherein each treatment group comprises 200 laying hens; 200 hatchling-period laying hens of each treatment group of examples 1, 2, 3 were compared with the 200 hatchling-period laying hens of the control group for 5 weeks of growth.
In the vitamin mixture of the feed raw material:
the trace folic acid can enhance the lipase activity of the intestinal contents of chickens, promote the decomposition of proteins in the intestinal tracts of young chickens to generate polypeptide, and simultaneously, the folic acid can stimulate the secretion of lipase and enhance the effect of lipase activity, so that the utilization rate of crude fat is improved.
Methionine is one of amino acids necessary for the growth of livestock animals, is a framework amino acid of biological synthetic protein, and methionine and lysine are essential amino acids for the development of chickens; meanwhile, as protein supplementation is crucial for the laying hens in the young period, the protein intake of the laying hens in the young period can be obviously increased by adopting the formula amount of methionine, and meanwhile, the laying hens in the young period can be promoted to develop, gain weight and enhance liver and kidney functions.
Pantothenic acid can prevent the occurrence probability of slow growth, reproductive dysfunction, reduced adaptability and the like of the laying hens in the young period, and creates important conditions for the future growth and development of the laying hens.
Because the weight of the laying hen in the young period is increased rapidly, the necessary iron element in the growing process of the blood meat is supplemented by the addition of ferrous sulfate, so that the low-pigment microcytic anemia of the laying hen in the young period caused by iron deficiency can be effectively prevented.
The citric acid can promote sucrose conversion, and has flavor improving effect.
In the Chinese herbal medicine additive of the feed raw materials:
the prepared rehmannia root and the Chinese angelica are selected for compatibility, and the dosage proportion relation is 2:1, simultaneously, the angelica and the white paeony root are selected for compatibility, so that the vitality of the young layer chicken can be improved, the nutrition absorption can be accelerated, and the balance of the muscle mass of the young layer chicken can be regulated. The radix Salviae Miltiorrhizae in the Chinese herbal medicine additive can enrich blood, promote the growth of young chicks, enhance resistance, and enhance effects when matched with radix Angelicae sinensis. The deer horn gum is used together with astragalus and deer horn gum, which is more beneficial to the growth and survival of the laying hens in the young period and prevents the immune system diseases of the laying hens.
The following is a table for comparing the growth of the layer in the young period
The feed for the young layer chickens provided by the invention can be used for better weight increment, accelerating the growth and development of the young layer chickens, enabling the layer chickens to spend the young layer period more quickly, and well ensuring the survival rate of the young layer chickens.
Of course, the present invention is capable of other various embodiments and its several details are capable of modification and variation in light of the present invention, as will be apparent to those skilled in the art, without departing from the spirit and scope of the invention as defined in the appended claims.
