Description
Technical Field
The invention relates to the technical field of animal feeds, and particularly relates to high-fat milk powder for kittens as well as a preparation method and application thereof.
Background
According to the report, the death rate of the pet cats ranges from 50% to 90% from birth to the adult stage. There are many factors responsible for the death of kittens, with insufficient energy intake being one of the most important causes. Fats are rich in essential fatty acids required by animals and are a major source of energy for animals.
CN113349307A provides a pet milk powder, which comprises the following components: the whole camel milk powder, the cordyceps sinensis, the medlar, the amino acid components, the compound vitamins, the compound mineral substances, the protein and the prebiotics, the pet milk powder has the advantages of rich nutrition, easiness in absorption and the like, and cannot become fat after being drunk for a long time, and the protein, fat, vitamin and mineral substance contents in the pet milk powder are higher than those of milk, so that the pet milk powder is beneficial to improving the immunity of animals and is an excellent pet nutrition supplement source.
CN106804877A provides a formula pet milk powder, which is composed of the following components: goat milk powder, whey protein powder, cricket protein powder, lecithin, oligosaccharide, oat puffed powder and gastrodia tuber powder. The formula pet milk powder provided by the invention is reasonable in formula, does not contain any additive, contains lecithin and oligosaccharide, and can ensure that the young pet needs nutrition every day and improve the immune mechanism of the young pet.
Although the prior art discloses the formula milk powder for pets, no special milk powder for kittens is provided, but the requirements of kittens on fat demand and utilization are special, the kittens can well absorb and utilize breast milk fat, but the fat in the milk powder is difficult to digest and utilize, and diarrhea can be caused when the milk powder is fed. The reason for this is, on the one hand, that the digestive system of kittens is not developed well and that the amount of pancreatic lipase and bile secreted by the gastrointestinal tract is not sufficient to completely digest the exogenous fat. On the other hand, the fatty acids in the exogenous fats (soybean oil, phospholipid oil, etc.) exist in the form of POP structure, and the saturated fatty acids are high in content and are not easy to digest and absorb, while the fatty acids in the breast milk mainly exist in the form of OPO structure which is easy to digest and absorb. Therefore, the energy level is a main factor for limiting the growth and development of the kittens. In addition, cats are weaned about 8 weeks after birth, and weaning also causes stress to kittens, which in turn causes diarrhea and affects their growth and health.
Therefore, in order to relieve weaning stress of the kittens and meet the nutritional requirements for growth and development of the kittens, the development of high-fat milk powder with balanced fatty acid and high utilization rate becomes a key point of nutrition research of the kittens.
Disclosure of Invention
Aiming at the defects of the prior art, the invention aims to provide high-fat milk powder for kittens and a preparation method and application thereof, wherein the high-fat milk powder for kittens is based on fatty acid of grease and milk fat of kittens, a fat combination with the most suitable fatty acid composition and structure distribution is prepared according to an ideal fatty acid model of the kittens and the special efficacy of functional fatty acid, and a specific process technology is adopted for treatment, so that the fat combination becomes multifunctional structure fat which is more beneficial to digestive utilization of the kittens, and the stress response of the kittens after weaning can be relieved and the growth of the kittens can be promoted.
In order to achieve the purpose, the invention adopts the following technical scheme:
in a first aspect, the high-fat milk powder for the kittens comprises the following components in parts by weight: 20-30 parts of fat component, 15-30 parts of protein component, 35-45 parts of carbohydrate, 1-3 parts of vitamin component and 2-5 parts of mineral component;
the fat component is a combination of DHA algae oil powder, medium chain triglyceride, tributyrin, OPO structural lipid and lecithin.
According to an ideal fatty acid model of the kitten and the special effects of functional fatty acids, the high-fat milk powder provided by the invention enables the fatty acid composition in the final milk powder to be very close to that of the cat breast milk and other nutritional ingredients to be close to the breast milk according to the fatty acid composition of grease and the milk fat of the cat breast milk, so that the requirements of growing development of the kitten on nutrition can be met, the growth of the kitten can be further promoted, the diarrhea rate of the kitten can be reduced, and the stress response of the kitten after weaning can be relieved.
DHA algal oil powder is added into the fat component, so that weaning stress of the kittens can be effectively solved, the milk powder has light fishy smell and good palatability, and feeding of the kittens is promoted; the medium chain triglyceride and the tributyrin can be decomposed into caprylic acid, capric acid and butyric acid under the action of the intestinal pancreatic lipase, the caprylic acid, the capric acid and the butyric acid can rapidly supply energy to organisms, and the medium chain fatty acid has the bacteriostatic action, can adjust intestinal flora, repair intestinal mucosal injury and improve the immunity of the organisms; the OPO structural ester can be hydrolyzed into short-chain saturated fatty acid and unsaturated fatty acid which are better digested, so that the absorption of fat and other nutrient components by the kittens is improved; the fat component of the invention can make the milk powder integrally meet the nutritional requirements of young cats and promote the growth of the young cats through the matching of DHA algae oil powder, medium chain triglyceride, tributyrin, OPO structure fat and lecithin.

Test example 1
200 healthy and disease-free Russian blue cat kittens with similar weights and ages were selected, randomly divided into 20 groups of 10 cats, and fed with the milk powders of examples 1-11 and comparative examples 1-7, respectively. Daily at 8, 11, 00, 15 and 18. Control 1 was fed breast milk only and control 2 was fed commercially available kitten milk powder.
Wherein the diarrhea rate (%) = total number of diarrhea in the group of kitten x 100/(total number of kitten in the group x number of test days);
fat digestibility (%) = (fat intake-fat content in feces) × 100/fat intake.
The test results are shown in Table 1.
TABLE 1
As can be seen from the data in table 1, the nutritional ingredients of the high-fat milk powder for the kittens in the embodiments 1 to 3 of the invention are closer to breast milk, and are easy to be digested and absorbed by the kittens, so that the kittens can be better promoted to grow rapidly, and the survival rate of the kittens is higher, wherein the daily gain of the kittens is more than 9.5 g/day, the fat digestion rate is more than 90%, and the effect is equivalent to that of breast feeding; compared with breast feeding, the diarrhea rate of the kittens is below 0.5 percent after the kittens use the high-fat milk powder, which shows that the milk powder provided by the invention can effectively reduce the diarrhea rate of the kittens.
From examples 4 and 5, it can be seen that when the mass ratio of the DHA algal oil meal, the medium chain triglyceride, the tributyrin, the OPO structural lipid, and the lecithin in the fat component is not within the range defined by the present invention, the daily gain of kittens is 8.29 or 7.19 g/day/cat, the fat digestibility is 88.01% or 86.38%, and the diarrhea rate is 4.76% or 3.81%, all indexes are reduced, which indicates that the mass ratio of each component in the fat component has an influence on the beneficial effects of the milk powder;
from examples 6 to 9, it can be seen that the lack of whey protein, casein, skimmed sheep milk powder and taurine in the protein components can reduce the daily gain of kittens and increase the diarrhea rate when any one of the components is absent;
from examples 10-11, it can be seen that the mass ratio of lactose, galacto-oligosaccharide and fructo-oligosaccharide in the carbohydrate also affects the effect of the milk powder in improving the daily weight gain, increasing the fat digestibility and reducing the diarrhea rate of kittens; as can be seen from the comparison between the example 1 and the comparative examples 1-2, when the vitamin component and the mineral component are added into the high-fat milk powder for the kitten, the nutrition of the milk powder can be more comprehensive, and the growth of the kitten can be better promoted;
from comparative examples 3 to 7, it is understood that DHA algal oil powder, medium chain triglyceride, tributyrin, OPO structural lipid and lecithin in the fat component have a synergistic effect in increasing daily gain, fat digestibility and reducing diarrhea rate of kittens, and the effect of the milk powder is deteriorated in the absence of any one of the components.
Therefore, the high-fat milk powder for the kittens provided by the invention can fully meet the nutrition required by the growth of the kittens, is easily digested and absorbed by the kittens, effectively reduces the diarrhea rate of the kittens, can improve the immunity of the kittens, and promotes the rapid growth of the kittens.
