Problems solved by technology

However, there are few studies on the simultaneous use of fermented raw materials and exogenous acidic additives, and the optimal ratio of various fermented raw materials and the optimal amount of additives will be a long-term research topic

Embodiment 1

[0021] Example 1: Effects of each addition amount combination on feed intake of piglets before weaning

[0022] In this experiment, 56 lactating sows were selected from the same farm, 8 per group. A total of 573 piglets, 82 in group A; 80 in group B; 81 in group C; 83 in group D; 84 in group E; 82 in group F and 81 in the control group. Feed the creep feeds produced by the combination of the 6 additions respectively, start the creeping at the age of 14 days, and wean at the age of 22-28 days. The creep feed intake of piglets in each group at the age of 14-22 days was counted separately.

[0023] Table 1: Feed intake of piglets in the experimental group before weaning (g)

[0024]

[0025] It can be seen from Table 1 that the feed intake of piglets in group D before weaning was the largest, and the feed intake of groups B, D, and F was significantly higher than that of groups A, C, E and the control group. This indicated that the addition combination of D group had the st...

Embodiment 2

[0026] Example 2: Effects of each addition amount combination on piglets' weaning weight and feed intake in the first 3 days after weaning

[0027] The samples of lactating sows and piglets in this experiment are the same as those in Example 1, and on the basis of Example 1, the weaning weight of the weaned piglets and the feed intake of creep feed after weaning were counted respectively.

[0028] Table 2: Weaning weight and feed intake (g) of piglets in the test group in the first 3 days after weaning

[0029]

[0030] It can be seen from Table 2 that group F has the largest feed intake, reaching 347g on the third day after weaning, which is significantly higher than other groups and the control group. Group D and Group B followed, and Group D also reached more than 300g on the third day. This indicated that the addition combination of F and B groups was beneficial to increase the feed intake of piglets after weaning.

Embodiment 3

[0031] Example 3: Effects of various addition amount combinations on the survival rate of piglets before weaning

[0032] In this experiment, a total of 146 lactating sows from different batches in the same farm were selected, with a total of 1468 healthy piglets. The number of sows and piglets in each group is as follows. The 6 addition combinations and the creep feed produced without adding fumaric acid and fermented soybean meal were fed respectively, the creeping was started at the age of 14 days, and the cows were weaned at the age of 22-28 days. The number of weaned piglets and survival rate of piglets in each group were counted separately.

[0033] Table 3: Survival rate of piglets in the experimental group before weaning

[0034]

[0035]

[0036] It can be seen from Table 3 that the survival rate of piglets in group E before weaning is the highest, reaching 99.5%, followed by group B. The survival rate of group C and control group was relatively low. Except ...

Abstract

The invention relates to a composition for adjusting and controlling the acidity of a creep feed and an application of the composition. The composition comprises the following components in parts by weight: 10-18 parts of fermentation type components, and 0.08-0.18 part of an exogenous acidic additive and is used for the creep feed. The creep feed comprises the following components in parts by weight: 27-35 parts of corn, 12 parts of puffing corn, 10-18 parts of fermentation type components, 10-15 parts of whey powder, 5-8 parts of milk powder, 4-6 parts of glucose, 4-5 parts of dried porcine soluble, 2-4 parts of plasma protein powder, 2-3 parts of soybean oil, 1-3 parts of calcium hydrogen phosphate, 0.5-1 part of stone powder, 0.5-1 part of salt, 0.2-0.5 part of composite mineral substance additives, 0.15 part of choline chloride, 0.08-0.18 part of exogenous acidic additives, 0.05-0.08 part of threonine, 0.04-0.06 part of tryptophan, 0.02-0.04 part of lysine, 0.02-0.03 part of methionine, 0.02-0.04 part of an antioxidant, and 0.01-0.02 part of a mildewproof agent. Compared with the prior art, the composition can adjust and control the acidity of intestinal tracts of piggies, adjust the microbial population mechanisms of gastrointestinal tracts, reduce anti-nutritional factors and reduce the generation probability of nutritive diarrhoea.

Description

technical field [0001] The invention belongs to the technical field of pig feed, and relates to a composition for regulating the acidity of creep feed and an application thereof. Background technique [0002] Piglet creep feed is the carrier for piglets to transition from milk to solid feed. The digestive tract of lactating piglets is not fully developed and lacks a variety of digestive enzymes, while creep feed can promote the development of piglet digestive tract and the formation of various digestive enzymes. , It is of great significance for piglets to accept solid feed. Successful creep feed can improve the health of piglets before and after weaning, and reduce the stress of weaning piglets. Therefore, this also puts forward higher requirements for the design of the creep feed. The design of the creep feed should take into account both the food-attracting performance and the internal nutritional level of the piglets. [0003] In recent years, with the rapid developmen...
