Problems solved by technology

The invention patent declared by the inventor in the previous period is a dynamic feeding method to improve the utilization rate of pig feed (Wu Xin, et al. A dynamic feeding method to improve the utilization rate of pig feed, application number: 201310097752.X), this method was first proposed A feasible method of dynamic feeding, but this method requires multiple feed changes in a day, so this method brings inconvenience to the operation of artificially fed group animals
At present, the feeding of most sow groups is still manual operation.

Embodiment 1

[0021] The invention relates to a feeding method of a dynamic nutrient level feed for sows, which is a feeding method used by the present invention for feeding late-gestation sows from 80 days of gestation to delivery.

[0022] 1. Select raw materials according to feeding standards, including corn, soybean meal, wheat, wheat bran, corn DDGS, fish meal, calcium hydrogen phosphate, stone powder, lysine 98, soybean oil, baking soda, salt, premix, etc., according to the current Raw materials for formulating basal rations according to the feeding standards are different. Refer to the feeding standards (1998) published by the National Research Council (NRC) and the Chinese pig feeding standards (2004) to prepare the corresponding stage. Diet A with the nutritional level. Diet A contains crude protein (16.48%), crude fat (4.09%), salt (0.4%), crude fiber (4.18%), etc. The feed ingredients and their nutritional levels are shown in the table 1;

[0023] 2. Then, on this basis, formula...

Embodiment 2

[0033] A simple feeding method of dynamic nutrient level feed for sows. This is the feeding method of the present invention for raising lactating sows from gestation 110 days to after giving birth to weaning.

[0034] 1. According to the current feeding standards, select raw materials and formulate basal rations with different nutritional requirements. Refer to the current commonly used feeding standards published by the National Research Council (NRC) (1998) and Chinese pig feeding standards. Breeding standard (2004), formulating ration A with corresponding nutritional level; ration A contains crude protein (16.48%), crude fat (4.09%), salt (0.4%), crude fiber (4.18%), etc. , Feed ingredients and their nutritional levels are shown in Table 1.

[0035] 2. On this basis, formulate a B diet that reduces the levels of nutrients such as crude protein, crude fat, and salt by about 5-30%. Among them, crude protein (13.61%), crude fat (2.92%), salt (0.3%), crude fiber (4.42%), etc....

Abstract

The invention discloses a method for feeding sows dynamically according to nutritional levels. The method comprises the following steps: A, selecting raw materials and preparing a daily ration A with the nutritional level at the corresponding stage; B, preparing a daily ration B with reduced nutrient level in crude protein, crude fat and salt, wherein the daily ration B comprises corns, bean pulp, wheat, wheat bran, corn DDGS, calcium hydrophosphate, mountain flour, lysine 98, soya-bean oil, baking soda and salt; C, feeding the daily ration A in the morning from 7am to 12pm, and feeding the daily ration B at the afternoon from 12pm to 21pm; and D, feeding twice every day and half for the morning and the afternoon respectively, and adjusting appropriately according to the previous feed intake. The method is feasible and is simple and convenient to operate, the feed intake of sows and the utilization rate of the feed are effectively improved, dynamic feeding for sows can be carried out conveniently, the quality of milk of sows is enhanced, the reproductive performance is improved, the feeding cost is lowered, and ammonia gas and other harmful gas in pigpen air is reduced.

Description

technical field [0001] The invention belongs to the technical field of pig feed feeding, and more specifically relates to a feeding method of dynamic nutrient-level feed that increases the feed intake of sows and improves the health level of sows, and is especially suitable for feeding sows in late pregnancy and lactation stages . Background technique [0002] Low feed intake of lactating sows is a major problem in current pig production, especially for modern lean breeds of lactating sows (Dong Guozhong. Importance of feed intake of lactating sows. Animals Nutrition Acta, 2007, 19: 446-453). Loss of appetite is a common phenomenon during pregnancy in sows. Low feed intake during lactation can have a detrimental effect on the reproductive performance of breeding pigs, leading to problems such as insufficient nutrient intake, postpartum anemia, and weak piglets, which not only affect sows Moreover, it will affect the growth and development of piglets. More seriously, it wil...
