Technical Field

[0001] The invention relates to the technical field of feed, in particular to a pig fattening feed additive and compound feed containing amino acid chelate. Background Art

[0002] Pork is the main meat product consumed by Chinese residents, and its production and consumption are both world-leading. The development of the pig farming industry is of great significance to ensuring the safe supply of domestic meat.

[0003] At present, as pig farming gradually develops towards scientific and large-scale development, the market has higher requirements for the breeding industry. Improving the body shape of pigs, increasing lean meat rate and meat quality have become the main means for farmers to improve economic benefits. The digestive system of pigs in the fattening stage is already perfect, the fat tissue grows vigorously, the lean meat rate is reduced, and a large amount of energy and protein are required. If the feed is not properly matched, it will not only fail to meet the growth needs of pigs, but also lead to increased back fat thickness and reduced lean meat rate, and also increase the mortality rate.

[0035] Comparative Example 1

[0036] Different from Example 1, betaine was not added to the pig fattening feed additive, but was replaced by an equal amount of theaflavins.

[0037] Comparative Example 2

[0038] The difference from Example 1 is that the theaflavins are not added to the pig fattening feed additive, but are replaced by an equal amount of betaine.

[0039] Comparative Example 3

[0040] The difference from Example 1 is that the percentage of betaine is 5%, and the percentage of theaflavins is 8%.

[0041] Comparative Example 4

[0042] The difference from Example 1 is that the amino acid chelate is replaced by inorganic trace elements, and the content of each element is the same as that in Example 1.

[0043] 400 healthy fattening pigs weighing about 50 kg were selected. The experimental pigs were of the "Du Changda" breed and randomly divided into 8 groups, with 50 pigs in each group. Feeding was carried out as follows:

[0044] Treatment group 1: basic diet + 1% of the pig finishing feed additive of Example 1.

[0045] Treatment group 2: basic diet + 1% of the pig finishing feed additive of Example 2.

[0046] Treatment 3: basic diet + 1% of the pig finishing feed additive of Example 3.

[0047] Treatment group 4: basic diet + 1% of the pig fattening feed additive of comparative example 1.

[0048] Treatment 5: basic diet + 1% of the pig fattening feed additive of Comparative Example 2.

[0049] Treatment group 6: basic diet + 1% of the pig fattening feed additive of comparative example 3.

[0050] Treatment group 7: basic diet + 1% of the pig fattening feed additive of comparative example 4.

[0051] Control group: basal diet.

[0052] The basic diet consists of corn, peanut meal, bran and sweet potato flour in a mass ratio of 50:20:18:25.

[0053] During the test, each group of pigs was free to eat and drink water. The amount of feed to be added next time was estimated based on the amount added to the trough each time and the remaining amount. The amount of feed was gradually increased to avoid waste. Feed was added three times a day, and immunization and deworming were performed as usual. The test lasted for 30 days. The weight of each pig was measured at the beginning and end of the test, and the average daily weight gain was calculated. The total feed intake during the test in each pen was measured, and the average daily weight gain and feed-to-meat ratio were calculated. The incidence and mortality were recorded, and the incidence and mortality were calculated. After the test, 5 pigs of similar weight were selected from each group for slaughter, and the back fat thickness and lean meat rate were measured. The results are shown in Tables 1 and 2.

[0054] Daily weight gain = (final weight - initial weight) / number of test days;

[0055] Feed-to-meat ratio = average daily gain / average feed intake.

[0056] Table 1 Growth indexes of pigs in each treatment group

[0057]

[0058] As can be seen from Table 1, compared with the control group, the average daily weight gain of the present invention is higher than that of the control group, and at the same time, the feed-to-weight ratio is reduced, indicating that the feed additive for pigs during the fattening period of the present invention accelerates the growth rate of fattening pigs and reduces the feed-to-weight ratio. Backfat thickness is an important carcass trait of pigs, and backfat thickness is negatively correlated with lean meat rate. It can be seen from the control group that the feed additive for pigs during the fattening period of the present invention can reduce the backfat thickness of fattening pigs and increase the lean meat rate. Betaine and theaflavins can synergistically improve muscle composition and fat absorption, promote the decomposition of pig fat, and increase the lean meat rate of pig carcasses. Treatment group 4 did not add betaine, treatment group 5 did not add theaflavins, and treatment group 6 changed the ratio of the two, and the fattening effect on pigs became worse, and the lean meat rate decreased; it can be seen from treatment groups 4 and 5 that betaine and theaflavins in the feed additive for pigs during the fattening period can promote the growth of pigs and increase the lean meat rate, and the two act synergistically. In the treatment of group 7, the amino acid chelate trace elements were replaced with inorganic trace elements, and not only the fattening effect was worse, but also the immunity of the pigs decreased, indicating that the amino acid chelate trace elements are beneficial to improving the immunity of pigs and promoting the growth of pigs. In summary, the feed additive for pig fattening period of the present invention is comprehensive and balanced in nutrition, and the components are reasonably matched, which can effectively improve the growth rate and lean meat rate of pigs, and is non-toxic and residue-free. It is a safe and efficient feed additive for pig fattening period, which solves the problems of slow growth and low lean meat rate of pigs during fattening period.

[0059] It can be seen from the above embodiments that the present invention provides a pig fattening feed additive and compound feed containing amino acid chelate, which can effectively improve the growth rate and lean meat rate of pigs, is non-toxic and residue-free, and is a safe and efficient pig fattening feed additive, which solves the problems of slow growth and low lean meat rate of pigs during the fattening period.

[0060] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
