Embodiment 1

[0018] After many years of follow-up testing of more than 200 barley seeds, stems, barley seedlings, and whole-plant barley samples in many places and varieties, the inventor found that six common mycotoxins in Yunnan barley (aflatoxin B1, deoxynivalenol, gibberella zebras ketene, fumonisins, T-2 toxins and ochratoxins) were rarely detected, and none of them exceeded the standard, and their safety was significantly better than that of conventional grain-based feed materials such as corn, bran and DDGS. The following table shows the measured values ​​of the main nutrients of several kinds of barley and bran (in Yunnan).

[0019] Table 1 Dry matter basis of measured values ​​of main nutrients of barley products, whole plant barley and bran, unit %

[0020]

[0021] It can be seen from the above table that the starch content of barley seeds is twice that of bran, so the net energy level it can provide is much higher than that of bran, and the crude fiber level of straw or whea...

Embodiment 2

[0023] After the whole barley plant matured and dried naturally in the field, when the seed moisture was lower than 20%, the above-ground part was harvested, crushed to 98% and passed through an 80-mesh sieve, and the experimental ration for lactating sows was prepared, and compared with the traditional bran ration, Measure the nutritional level of different diets and calculate the price cost of different diets.

[0024] Table 2 Comparison of ratio, cost and nutritional level between traditional bran ration and whole-plant barley ration for lactating sows

[0025]

[0026]

[0027] Table 2 shows two formulas comparing the traditional bran diet and the whole-plant barley diet for lactating sows. The soybean meal used in this experiment is high-protein soybean meal with a protein content of 43%. From the measured data in Table 2, it can be seen that when the proportion of wheat bran in the diet reaches 30%, the net energy of the diet can only reach 2200 kcal / kg, the crude ...

Embodiment 3

[0029] The traditional bran diets A, B and the whole-plant barley diets C, D were used to feed lactating sows, and the weaned individual weight of piglets at 30 days old, the individual weight of 60 days old piglets and the annual productivity of sows (annual fattening pigs provided number).

[0030] Table 3 Feeding test results of traditional bran ration and whole-plant barley ration Unit: head, kg

[0031]

[0032] As can be seen from the results of Example 3, the use of whole plant barley can completely replace the bran in the diet of lactating sows, and can obtain better reproductive benefits, improve the health status of piglets, and improve the daily gain of piglets. Therefore, when piglets are 30 At the age of weaning, the individual weight of the piglets suckled by sows in the whole plant barley group increased by 34.5%, and the individual weight of 60-day-old piglets increased by 18.7%, and the number of fat pigs provided by sows increased by 32.3% %, greatly impr...

Abstract

The invention relates to a lactational sow daily ration prepared by using whole-plant barley for replacing bran. The whole-plant barley is used for completely replacing the bran in the lactational sowdaily ration, wherein the whole-plant barley is a harvested overground part when the grain moisture is lower than 20% after husky barley is mature and naturally air-dried in a field, and is smashed to 98% and sieved through a 60-80-mesh sieve. The preferred daily ration is prepared from, by weight, 55-59% of corn, 3% of glucose, 17.5-20.5% of bean pulp, 3.5-5% of fish meal, 9-15% of the whole-plant barley, 1% of soya-bean oil, 1% of a 1% pregnant sow premix, 1.4% of mountain flour, 0.25-0.6% of light calcium, 0.1-0.2% of a sodium chloride premix, 0.1% of choline, 0.4% of baking soda, 0.18-0.2% of lysine and 0.07-0.1% of methionine. The lactational sow daily ration prepared by using the whole-plant barley for replacing the bran has the advantages that the whole-plant barley is used for replacing all the bran, thereby reducing the harm caused by mold contamination to the sow daily ration, simplifying the work of planting, harvesting and storage of the whole-plant barley, providing the higher nutritional level and friendlier environmental nitrogen emission amount, and reducing the cost of the lactational sow daily ration.

Description

technical field [0001] The invention relates to the field of animal husbandry, in particular to a ration for lactating sows in which bran is replaced by whole plant barley. Background technique [0002] In pig production, the diet nutrition and composition of sows play an important role in the reproductive performance of sows, which in turn determines the production efficiency of pigs. In traditional sow diets, in order to ensure the health of the digestive tract of sows and maintain a suitable body condition, more than 30% of bran must be included. However, bran is a raw material with low net energy and high crude fiber. The bran sow diet can basically meet the nutritional needs of sows during pregnancy, but it cannot meet the lactation and postpartum recovery needs of lactating sows, especially high-yield (litter size ≥ 10) lactating sows. How to solve the contradiction between dietary crude fiber and high net energy level has always been the key technology to overcome hi...
