Description

Feed for lactating sows and preparation method thereof

technical field

The invention belongs to the field of feed, and relates to a feed for sucking sows and a preparation method thereof.

Background technique

The fecundity of sows is the most important link in the pig production process, and the number of healthy weaned piglets that each sow can provide each year determines the benefits of pig production. my country is a traditional big pork consumption country. Pork is the main source of meat for our people, accounting for more than 60% of daily meat consumption. However, the pig production level in my country is still relatively backward compared with developed countries in the world. At present, the main problems of lactating sows in my country are low feed intake and insufficient lactation, which lead to slow growth of suckling piglets; low immunity of sows and piglets, and high mortality of suckling piglets.

Different growth stages of pigs have different requirements for nutrients. During the lactation stage, not only the nutritional needs of the mother but also the nutritional needs of the piglets must be met, so the sows need to eat as much feed as possible. Since the sows are relatively weak after delivery and their desire to eat food is relatively poor, it is necessary to fully consider the nutritional needs of the sows, the palatability of the feed, and improve the immune performance of the sows during the lactation period.

In view of this, it is necessary to provide a feed suitable for lactating sows to meet the nutritional needs of lactating sows.

Contents of the invention

Aiming at the problems of low feed intake, poor lactation ability, and slow growth of suckling piglets in my country at present, the first purpose of the present invention is to provide a feed for lactating sows, which can significantly increase the weaning litter weight of suckling piglets. , the number of weaned piglets.

The second object of the present invention is to provide a preparation method of the above feed for lactating sows.

The first purpose of the present invention is achieved through the following technical solutions:

A feed for lactating sows, comprising the following components in parts by weight: 40-70 parts of corn, 10-30 parts of soybean meal, 0-15 parts of flour, 1-5 parts of fish meal, 1-3 parts of fish oil, calcium hydrogen phosphate 0.4-1.0 parts, 0.1-0.4 parts of lysine hydrochloride, 0.1-1 parts of arginine, 0.1-0.5 parts of valine, 0.08-0.2 parts of choline chloride, 0.03-0.10 parts of elongin, salt 0.1～0.4 parts, 4 parts of premix.

Further, the feed for pregnant sows includes the following components in parts by weight: 62.20 parts of corn, 21.9 parts of soybean meal, 5 parts of flour, 3 parts of fish meal, 2 parts of fish oil, 0.65 parts of calcium hydrogen phosphate, lysine salt 0.17 parts of salt, 0.4 parts of arginine, 0.24 parts of valine, 0.15 parts of choline chloride, 0.05 parts of elongate, 0.24 parts of table salt, and 4 parts of premix.

The nutritional level of the feed in the present invention is digestible energy: 3380kcal/kg; crude protein: 17.75%; lysine: 1.0%; cystine+methionine: 0.51%; threonine: 0.60%; tryptophan: 0.21% ; Valine: 0.87%. Guaranteed Lysine: Methionine + Cysteine: Threonine: Tryptophan = 100:51:60:21.

During the lactation stage, sows must not only ensure the growth of the mother, but also meet the needs of the piglets for breast milk. Therefore, the energy, protein, and amino acid requirements of lactation feeds are higher than those of pregnancy feeds. Through the ideal protein model, the essential amino acids that are lacking in feed materials are supplemented, and amino acid balanced rations are formulated to ensure the supply of various essential amino acids and meet the maintenance needs, growth needs, and lactation needs of lactating sows, so that sows will not be lactating. Period fat loss is too serious.

Corn is known as the king of feed in my country. Because of its high energy, good palatability, high feeding value and moderate price, it is an indispensable feed raw material for pigs, chickens and other grain-consuming livestock and poultry. Corn contains 2% linoleic acid, which is the highest content in corn. Linoleic acid is octadecadiene fatty acid, which cannot be synthesized in animals and can only be provided by food materials. It is an essential fatty acid for animals. Soybean meal is rich in protein content, generally more than 40%, and the digestibility is 85% to 92%. It is a high-quality protein raw material, and the level of protein content is also a standard for measuring the nutritional value of feed.

Flour belongs to energy feed, but its crude protein content ranks first in cereals and is rich in B vitamins, which play a role in bonding during the pelleting process of feed, making the pelleting effect of feed better. As a high-quality protein feed raw material, fishmeal is rich in calcium and phosphorus, and contains some unknown growth-promoting factors. Improve the palatability of the feed, promote the feed intake of sows, increase the feed intake of sows, and improve the production performance of sows. Fish oil is rich in polyunsaturated fatty acids, most of which are essential fatty acids for animals. Studies have reported that adding fish oil to the diet of lactating sows can significantly increase the content of DHA and EPA in milk. Fish oil can reduce blood sugar and blood lipids and improve insulin resistance. Therefore, adding fish oil to the diet of sows in the late pregnancy and lactation period can stabilize blood insulin and leptin secretion, increase the feed intake of sows and improve the growth performance of suckling piglets.

The body of sows presents a negative balance of energy and nutrients throughout the lactation period, and the intake of dietary nutrients is not enough to meet the needs of lactation, especially energy, which requires mobilization of body reserves. The efficiency of valine in animals to produce ATP (adenosine triphosphate) is much higher than that of other amino acids. Valine can also be metabolized into succinyl coenzyme A in cells, thereby providing energy for mammary gland development and maintaining normal physiological functions, and promoting lactation. Lysine is the first limiting amino acid in pigs. It can not only be used as a substrate for protein synthesis, but also as a regulatory factor to regulate protein synthesis. Adding lysine can increase the birth weight and litter weight of piglets. Arginine can promote the development of mammary glands in sows, improve the development of intestinal mucosa in suckling piglets, improve the immune performance of piglets, increase the daily weight gain of piglets, and reduce the mortality of piglets.

The main ingredient of Yichangsu is soybean isoflavones. Soybean isoflavone is a kind of compound with weak estrogenic effect extracted from soybean. It has the same performance as estrogen and fully meets the needs of safe production of animal products.

Calcium: 17.5g; phosphorus: 5.0g; sodium chloride: 15g; copper: 250mg; iron: 2000-4000mg; manganese: 500-1000mg; zinc: 2500mg; 7.0mg; Selenium: 3mg; Vitamin A: 50～175KIU; Vitamin D3: 20～125KIU; Vitamin E: 1000～3000mg; Vitamin K: 50～150mg; Folic acid: 80～150mg; Niacin: 250～500mg; 600～1000mg; riboflavin: 100～150mg; vithiamine: 25～30mg; vitamin B6: 25～30mg; biotin: 5～10mg; vitamin B12: 0.5～2mg; the balance is carrier.

The carrier of the premix is one of corn flour, wheat flour, defatted rice bran, zeolite powder, bentonite or any combination thereof. Preferably, the carrier of the premix is zeolite powder.

A high level of vitamin E is added to the premix. Vitamin E is the vitamin most closely related to the reproductive performance of animals. It is an essential substance to maintain the normal structure and function of the reproductive system. The main mechanism by which it affects reproductive performance is through antioxidant action. Supplementing VE increases the content of VE in breast milk and piglet serum, enhances its antioxidant capacity, and improves immune performance, thereby improving the reproductive performance of sows and the growth performance of piglets.

The second purpose of the present invention is achieved through the following technical solutions:

A preparation method for above-mentioned feed for lactating sows, comprising the following steps:

(1) firstly mix lysine hydrochloride, arginine, valine, salt, choline chloride, and ethanol according to the formula quantity, then add the premix and mix evenly to obtain the mixture;

(2) Mix the materials step by step. The order of addition is to add half the amount of corn, soybean meal, flour, the mixture obtained in step (1), and the remaining corn. After mixing, spray the fish oil on the surface of the feed in a mist state. Mix evenly, enter the granulator to granulate, and obtain the finished feed for lactating sows.

In the step (2), the diameter of the annular membrane of the granulator is 3.0-4.0mm, the preparation temperature is 75-90°C, the mixing time is 90-150 seconds, and the compression ratio is 1:5-8.

Preferably, the annular membrane aperture of the granulator is 3.5mm, the conditioning temperature is 80°C, the mixing time is 120 seconds, and the compression ratio is 1:6.

Compared with the prior art, the present invention has the following beneficial effects:

(1) The present invention uses an ideal protein model to supplement the essential amino acids lacking in feed materials and formulate amino acid balanced rations to ensure the supply of various essential amino acids and to meet the maintenance needs, growth needs, and lactation needs of lactating sows, while ensuring Sows will not lose too much fat during lactation;

(2) The present invention adds a certain amount of fishmeal to the feed. Fishmeal belongs to animal protein feed, which is rich in nutrition and has strong palatability, and can significantly improve the feed intake of sows; fish oil has positive effects on reducing blood sugar and blood lipids and improving insulin resistance. It can stabilize blood insulin and leptin secretion, increase the feed intake of sows and improve the growth performance of suckling piglets;

(3) The addition of valine in the present invention can provide energy for mammary gland development and maintain normal physiological functions, and promote lactation; Yichangsu can promote the growth of animals, improve its reproductive performance, promote the development of animal mammary glands, and increase lactation. Arginine can promote the development of mammary glands in sows, improve the development of intestinal mucosa in suckling piglets, improve the immune performance of piglets, increase the daily weight gain of piglets, and reduce the mortality of piglets.

(4) The feed for lactating sows of the present invention has balanced nutrition, strong palatability, easy digestion, and can improve the immunity of sows. The feed can significantly improve the feed intake of sows and improve the weaning litter weight of suckling piglets. Reduce the mortality rate of piglets and increase the number of weaned piglets.
