Embodiment 1

[0033] A feed for lactating sows, which is composed of 622 grams of corn, 219 grams of soybean meal, 50 grams of flour, 30 grams of fish meal, 20 grams of fish oil, 6.5 grams of calcium hydrogen phosphate, 1.7 grams of lysine hydrochloride, Arginine 4 grams, valine 2.4 grams, choline chloride 1.5 grams, Yichangsu 0.5 grams, salt 2.4 grams, premix 40 grams.

[0034]The nutritional level of the feed in this example 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.

[0035] The preparation method of lactating sow feed in the present embodiment, comprises the following steps:

[0036] (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;

[0037] (2) Mix the materials st...

Embodiment 2

[0039] A feed for lactating sows, which consists of 591 grams of corn, 220 grams of soybean meal, 80 grams of flour, 30 grams of fish meal, 20 grams of fish oil, 6.5 grams of calcium hydrogen phosphate, 1.7 grams of lysine hydrochloride, 4 grams of arginine gram, 2.4 grams of valine, 1.5 grams of choline chloride, 0.5 grams of Yichangsu, 2.4 grams of salt, and 40 grams of premix.

[0040] The nutrient level (composition and ratio of crude protein, digestible energy, lysine, threonine, and tryptophan) of the feed for lactating sows in this example is similar to that of Example 1, and the preparation method is the same as Example 1.

Embodiment 3

[0042] A feed for lactating sows, which consists of 569.9 grams of corn, 221 grams of soybean meal, 105 grams of flour, 25 grams of fish meal, 20 grams of fish oil, 6.5 grams of calcium hydrogen phosphate, 1.8 grams of lysine hydrochloride, 4 grams of arginine gram, 2.4 grams of valine, 1.5 grams of choline chloride, 0.5 grams of Yichangsu, 2.4 grams of salt, and 40 grams of premix.

[0043] The nutrient level (composition and ratio of crude protein, digestible energy, lysine, threonine, and tryptophan) of the feed for lactating sows in this example is similar to that of Example 1, and the preparation method is the same as that of Example 1.

Abstract

The invention provides a nursing sow feed which comprises following ingredients 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, 0.4-1.0 part of calcium hydrophosphate, 0.1-0.4 parts of lysine hydrochloride, 0.1-1 part of arginine, 0.1-0.5 parts of valine, 0.08-0.2 parts of choline chloride, 0.03-0.10 parts ofgrowth promotion element, 0.1-0.4 parts of table salt and 4 parts of premix. The invention provides a preparation method of the nursing sow feed at the same time. The nursing sow feed is balanced innutrition, high in palatability and easy to digest, and can improve immunity of a sow; the feed intake of the sow can be increased significantly when the feed is eaten; the weight of weaning litter ofsuckling piglets is increased; a death rate of the piglets is reduced; and the quantity of the weaned piglets is increased.

Description

technical field [0001] The invention belongs to the field of feed, and relates to a feed for sucking sows and a preparation method thereof. Background technique [0002] 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. [0003] Different growth stages of pigs have different requirements for nutrients. During the lacta...
