Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of feed, in particular to a pig fattening period feed additive containing amino acid chelate and compound feed. BACKGROUND

[0002] Pork is the main meat consumption product of Chinese residents, and its output and consumption are in the leading position in the world. The development of pig industry is of great significance to guarantee the domestic meat food safety supply.

[0003] At present, with the gradual development of pig breeding towards scientific and large-scale, the market has higher requirements for breeding industry, and improving the body shape of pigs, increasing the lean meat rate and meat quality have become the main means for breeders to improve economic benefits. The digestive system of large pigs in the fattening stage is already perfect, the adipose tissue grows vigorously, the lean meat rate decreases, and a large amount of energy and protein is needed. If the feed is not reasonably matched, it not only cannot meet the growth needs of large pigs, but also will lead to increased back fat and decreased lean meat rate, and also will lead to increased mortality.

[0034] Preparation of the feed additive for fattening pigs: the above raw materials were crushed and put into a mixing tank, and mixed for 50 min to obtain the feed additive.

[0035] Comparative Example 1

[0036] Different from Example 1, the betaine was not added in the feed additive for fattening pigs, and was replaced by an equal amount of theaflavin.

[0037] Comparative Example 2

[0038] Different from Example 1, the theaflavin was not added in the feed additive for fattening pigs, and was replaced by an equal amount of betaine.

[0039] Comparative Example 3

[0040] Different from Example 1, the percentage content of betaine was 5%, and the percentage content of theaflavin was 8%.

[0041] Comparative Example 4

[0042] Different from Example 1, the amino acid chelate was replaced by inorganic trace elements, and the contents of the elements were the same as in Example 1.

[0043] Four hundred healthy fattening pigs of about 50 kg were selected, and the breeds of the test pigs were "Duchangda". The pigs were randomly divided into 8 groups, with 50 pigs in each group. The pigs were fed in the following manner:

[0044] Treatment 1 group: basal diet + 1% of the feed additive for fattening pigs of Example 1.​

[0045] Treatment 2 group: basal diet + 1% of the pig fattening period feed additive of Example 2.

[0046] Treatment 3 group: basal diet + 1% of the pig fattening period feed additive of Example 3.

[0047] Treatment 4 group: basal diet + 1% of the pig fattening period feed additive of Comparative Example 1.

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

[0049] Treatment 6 group: basal diet + 1% of the pig fattening period feed additive of Comparative Example 3.

[0050] Treatment 7 group: basal diet + 1% of the pig fattening period feed additive of Comparative Example 4.

[0051] Control group: basal diet.

[0052] The basal diet was composed of corn, peanut meal, bran and sweet potato powder in a mass ratio of 50:20:18:25.

[0053] The pigs in each group were allowed to eat and drink freely during the test period. The amount of feed added to the trough was gradually increased to avoid waste, and the amount of feed added to the trough was estimated according to the amount added each time and the amount remaining. The pigs were fed 3 times a day, and routine immunization and deworming were performed. The test lasted for 30 days. The body weight of each pig was measured at the beginning and end of the test, and the average daily gain was calculated. The total feed intake during the test was measured, and the average daily gain and feed conversion ratio were calculated. The incidence of disease and death was recorded, and the incidence and mortality rates were calculated. After the test, 5 pigs with similar body 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 gain = (final weight - initial weight) / test days;

[0055] Feed conversion ratio = average daily gain / average feed intake.

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

[0057]

[0058] As shown in Table 1, compared with the control group, the average daily weight gain of the present application is higher than that of the control group, and at the same time, the feed conversion ratio is reduced, which shows that the pig fattening period feed additive of the present application can accelerate the growth rate of the fattening pigs and reduce the feed conversion ratio. Backfat thickness is an important carcass trait of pigs, and backfat thickness is negatively correlated with lean meat rate. As shown in the control group, the pig fattening period feed additive of the present application can reduce the backfat thickness of the fattening pigs and improve the lean meat rate. Betaine and theaflavins can synergistically improve muscle composition and fat absorption, promote the decomposition of pig fat, and improve the lean meat rate of pig carcass. Treatment group 4 does not add betaine, treatment group 5 does not add theaflavins, and treatment group 6 changes the ratio of the two, which makes the fattening effect of pigs worse and the lean meat rate lower. As shown in treatment group 4 and treatment group 5, betaine and theaflavins in the pig fattening period feed additive can promote the growth of pigs and improve the lean meat rate, and the two have a synergistic effect. Treatment group 7 uses inorganic trace elements to replace amino acid chelated trace elements, not only the fattening effect is poor, but also the immunity of pigs is reduced, which shows that amino acid chelated trace elements are beneficial to improve the immunity of pigs and promote the growth of pigs. In summary, the pig fattening period feed additive of the present application has a balanced nutrition, reasonable component matching, can effectively improve the growth rate and lean meat rate of pigs, and is a safe and efficient pig fattening period feed additive, which solves the problems of slow growth and low lean meat rate of pigs during the fattening period.

[0059] As shown in the above examples, the present application provides a pig fattening period feed additive and a compound feed containing amino acid chelates, which can effectively improve the growth rate and lean meat rate of pigs, and is a safe and efficient pig fattening period feed additive, which solves the problems of slow growth and low lean meat rate of pigs during the fattening period.

[0060] The above only describes the preferred embodiments of the present application, and it should be noted that for those skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered as the protection scope of the present application.
