In order to maintain a good layer and make the layer high in yield and stable, in addition to good breeds and good feeding methods, the quality of the feed is the most critical. The rations of laying hens are generally best for satisfying the needs of the protein if they meet energy needs. In fact, it is also very important to feed protein feed to chickens. To be precise, the nutritional needs of chickens for protein are the nutritional needs of amino acids. Therefore, only adding vegetable protein feed (bean cake) to layer chicken diet can not, chickens can not produce more eggs, but also add appropriate amount of animal protein feed.
Because the animal protein feed contains incomplete essential amino acids. Incomplete amino acid, the high performance of chicken egg production can not be achieved. The main lack of essential methionine in the bean cake, fish meal in the essential amino acids are contained, especially contains more methionine. Therefore, in addition to addition of soybean cake in the diet of layer chickens, fishmeal should be fed to promote the production of eggs. Feeding chickens with diets supplemented with fishmeal can produce 250-260 eggs a year.
Feeding chickens with fishmeal has an effect of increasing egg production, but the price of fishmeal is too high. In particular, imported fishmeal containing 80% fish and 20% fish bones has a higher price. Feeding chickens with such fishmeal will raise the cost of feeding. The economic benefits are lower than those without fishmeal, which is very unacceptable for the rapid development of commercially-oriented laying hens. Therefore, in the feed formulation of large-scale chicken farms in many countries in Europe and America, most of them no longer use fishmeal (called no fish meal diet).
The preparation of fishmeal-free diets is not difficult. It is mainly aimed at the lack of methionine, vitamin B12 and vitamin A in the vegetable protein feed (bean cake). When the diet is not prepared with fishmeal, it should be added to the corn-bean meal diet. Feed methionine, vitamin B12, the amount should account for 18% to 20% of the diet, plus some more multi-dimensional poultry. In this way, the actual needs of the chicken for the protein can be satisfied, and the composition of the amino acids can be balanced, which can be used instead of fishmeal feeding for laying hens, so that the laying hens can produce more eggs, and 245-250 eggs can be produced one year. This results in only a dozen fewer eggs compared to the number of eggs laid with fish meal. Feeding chickens without fishmeal greatly reduces the cost of fishmeal. The economic benefits are far higher than the actual income of laying hens fed with fishmeal. Therefore, it is more cost-effective to break the argument that animal proteins cannot be replaced by other substances. .
In fish meal-free diets, methionine is not added, and betaine can be used instead of methionine. Using betaine instead of 50% or 100% synthetic methionine to feed egg breeders in the diet, the egg production rate, egg weight, fertilization rate, and deadweight rate were not significantly different from the control group. Hydatidiine hydrochloride replaces 50% or 100% of synthetic methionine in the diet during the late egg-laying period in Hyland brown hens, which can slow down egg production and increase feed conversion. All these indicate that the use of betaine instead of 50% or 100% of synthetic methionine in the diet has no adverse effect on egg production performance and nitrogen metabolism, and can also achieve the goal of multiple egg production. Therefore, it is feasible.
Alternative Tea
Substitute tea refers to the use of edible plant leaves, flowers, fruits (fruit), roots, etc., using the way of drinking tea (by brewing, boiling, etc.) is a kind of products commonly known.
Substitute tea is divided into leaf, flower, fruit and rhizome; The way of drinking the same as tea is generally composed of one or more items in the two categories of "medicine and food homology" and "can be used for health care" in the food classification stipulated by the Ministry of Health. Tea products made from the roots, stems, leaves or fruits of these plants.
The way of drinking the same as tea, generally by the ministry of Health provisions of food classification of medicine and food homologous category, can be used for health care category, two types of goods in the single or multiple items, with the roots, stems, leaves or fruits of these plants made of tea products.
Substitute tea has certain effect and auxiliary effect for some special groups, belonging to the health conditioning products.
