Laying hens fed fish meal is also not high

To keep a good egg, so that layers high and stable yield,[link widoczny dla zalogowanych], in addition to laying a good variety and good feeding method, feed quality is good or bad is the most critical. Laying hens with diet, to meet the energy needs of the general case, and then meet the protein needs is the best thing to. Protein feed actually fed to the chickens also have luxurious. Rather, the nutritional needs of the chicken protein is the nutritional needs of amino acids. Therefore, in laying hens diets add only vegetable protein feed (soybean) No, no more egg-laying chickens, but also fed Caixing amount of animal protein feed. Because vegetable protein feed containing the essential amino acid insufficiency. Amino acid insufficiency, the high performance of egg does not come out to play. The main lack of the necessary bean methionine and fish meal of chicken contains essential amino acids, in particular, contain more methionine. Therefore, in addition to the diet added layer cake, but also fed fish meal, chicken and more in order to promote egg production. Fish meal diet with added chickens, make an annual output of 250 to 260 one egg. With fish meal to feed the chickens, although the role of increased egg production, but the fish meal price is too high, especially with 80% and 20% of fish, fish bone meal imports more expensive, with such a meal to chickens, raising the cost too high, its economic benefits but lower than the diet without fish meal, which is the rapid development of commercial laying hens raised today, is very inappropriate. Therefore, it is a large chicken farm in Western countries to feed formula, most no longer use fish meal (known as non-fish meal diet) that is for this reason. Preparation of fish meal-free diet is not difficult, mainly for vegetable protein feed (soybean cake) and lack of methionine, vitamin B12 and vitamin A lack of actual configuration in the diet without fish meal, should be in the corn - soybean diet plus feeding methionine, vitamin B12, the amount attributable to the diet of 18% to 20%, plus some poultry multidimensional factors. This would meet the actual needs of the chicken protein,[link widoczny dla zalogowanych], amino acid composition can balance, you can replace the fish meal fed hens, to achieve the purpose of laying hens more than a year can make egg production ranged from 245 to 250. This is laying by the number of feeding fish meal compared to only produce less than a dozen eggs. Chickens do not have fish meal, fish meal significantly reduced the expenditure, the cost is much higher than the actual laying hens fed with fish meal income, and therefore more cost effective, thus breaking the animal protein is not replaced by other substances that can claim . In the non-fish meal diet, do not add methionine instead of methionine by betaine is required. Diet with betaine instead of 50% or 100% synthetic methionine fed chicken eggs,[link widoczny dla zalogowanych], egg production, egg weight, fertilization rate, death rate and other indicators of Amoy, as compared with the control group was not significant. Highland Brown laying in the late diet with betaine hydrochloride instead of 50% or 100% synthetic methionine,[link widoczny dla zalogowanych], can slow the rate of decline in egg production, feed conversion rate. All this shows that the diet with betaine instead of 50% or 100% synthetic methionine, on the laying performance, nitrogen metabolism without adverse effects, but also to achieve the purpose of laying more, it is feasible.
