Embodiment 2

[0034] The large group application test of embodiment 2 premix

[0035] The additive composite premix formula for gilts of the present invention is the same as that in Example 1

[0036] Experimental design: 817 LY gilts were selected for the experiment, including 399 gilts in the control group and 418 gilts in the experimental group. The experiment continued from the time the sows reached a body weight of 50kg until the end of the third estrus.

[0037] Experimental diet: the experimental diet used corn and soybean meal as the main raw materials, and the experimental group was fed the diet formulated with the gilt premix of the present invention. The control group was fed the diet formulated with commonly used fattening pig premix. The proportion of premix added is 4%.

[0038] Data collection: Carefully observe and record the health of each sow's limbs and hooves every morning from 0800 to 1000. The criteria for judging limb and hoof diseases in this experiment are: crack...

Abstract

The invention discloses a compound premix additive for improving bone development of replacement gilts. The compound premix additive is prepared from, by weight, 30-40 parts of vitamin complex, 40-60 parts of trace element composite, 30-40 parts of choline chloride, 40-60 parts of L-lysine hydrochloride, 10-15 parts of DL-methionine, 5-10 parts of L-threonine, 120-150 parts of calcium hydrophosphate, 120-150 parts of monocalcium phosphate, 250-280 parts of limestone powder, 90-110 parts of salt and 85-265 parts of bran. By adoption of the compound premix additive, bone toughness and strength of the replacement gilts can be improved, reserve quantity of nutrients such as vitamins, trace elements and the like in the replacement gilts is increased, and accordingly occurrence rate of the foot-and-leg disease of the gilts is decreased, health of feet and legs of the gilts is protected, and lives of the gilts are prolonged.

Description

technical field [0001] The invention relates to the field of animal husbandry, in particular to a compound premix additive for improving the bone development of gilts. Background technique [0002] In recent years, with the development of intensive production, the nutritional needs of gilts have become a new focus of animal nutrition research. Sow limb and foot disease is common and frequent all over the world, and it has become one of the main reasons for the culling of young sows. Studies have reported that the annual incidence of foot and foot disease in sows in large-scale pig farms in my country is generally above 30%, and some studies have even reported that the incidence of foot and foot disease in sows in the early pregnancy, middle and late stages and lactation period is as high as 72.5%, 72.9% and 76.0%, respectively. %. Due to the high culling rate of limb and foot disease in my country, a large number of gilts need to be supplemented every year. Therefore, the b...
