| Zusammenfassung: | The invention discloses a formula feed suitable for laying hens in winter as well as preparation and application thereof. The formula feed for the laying hens in winter consists of a daytime feed anda night feed. According to the energy-egg ratio difference caused by the temperature difference change of the laying hens in winter, the daytime feed and the night feed are accurately designed, the nutritional requirements of the laying hens for egg laying and energy maintaining are met, the production potential of the laying hens in winter is improved, the egg laying rate is increased by 6.1-11.1%, and the feed cost of a single chicken is saved by 0.4-0.6 yuan. According to the formula feed for the laying hens in winter, stress reaction of feeding of the two kinds of feed does not occur in the process of feeding the laying hens, the effect of transporting nutrient substances by organisms of the laying hens is enhanced, digestion and absorption of protein are promoted, and the immune response of the organisms is a |
