Problems solved by technology

In addition, about 60% of the cost of pig breeding in my country comes from feed, which leads to feed and feed additives largely affecting the quality of pig products and the safety of animal-derived food
In order to improve the growth rate of pork and feed remuneration, the abuse of antibiotics and chemical synthetic drugs in the market not only seriously exacerbated the decline of pork flavor and quality, but also endangered human health and caused hidden dangers to food safety

Embodiment 1

[0018] A pasture feed for producing pork with high linolenic acid and linoleic acid, which is mainly prepared from the following substances in weight percentage: 73.83% corn, 16.48% soybean meal, 1.63% bran, 5.00% alfalfa powder, 1.00% stone powder, Calcium hydrogen phosphate 0.40%, salt 0.4%, 98% lysine 0.24%, 98% tryptophan 0.02%, premix 1.0%.

[0019] 1% of the premix can provide the following weights per kilogram (kg) of the complete diet: vitamin A8000 IU; vitamin D 3 000 IU; vitamin E33.6 IU; vitamin B 2 3.2 mg; vitamin B 1 20.012 mg; niacin 16 mg; pantothenic acid 10mg; biotin 0.168 mg; folic acid 1.28 mg; copper 11.2 mg; iron 140 mg; zinc 65.6 mg; manganese 37.6 mg;

[0020] The nutrient level of the forage ration for the production of high linolenic acid and linoleic acid pork prepared in Example 1 is: digestible energy 3250Kcal / kg, crude protein 15%, calcium 0.59%, available phosphorus 0.26%, SID lysine 0.80%, SID egg + cystine 0.44%, SID threonine 0.50%, see Tabl...

Embodiment 2~4

[0022] See Table 2 for the composition of each raw material and the nutrient level of the forage ration for producing pork with high linolenic acid and linoleic acid provided in Examples 2-4. By adjusting the formula of the diet, the nutritional level of each embodiment was consistent.

[0023]

Embodiment 5

[0024] Embodiment 5 control experiment

[0025] A kind of pasture feed grain, without adding alfalfa grass powder, the weight percentages of other substances are: corn 71.05%, soybean meal 16.50%, bran 9.20%, stone powder 1.20%, calcium hydrogen phosphate 0.40%, salt 0.4%, 98% lye Amino acid 0.23%, 98% tryptophan 0.02%, premix 1.0%.

[0026] 1% of the premix can provide the following weights per kilogram (kg) of the complete diet: vitamin A8000 IU; vitamin D 3 000 IU; vitamin E33.6 IU; vitamin B 2 3.2 mg; vitamin B 1 20.012 mg; niacin 16 mg; pantothenic acid 10mg; biotin 0.168 mg; folic acid 1.28 mg; copper 11.2 mg; iron 140 mg; zinc 65.6 mg; manganese 37.6 mg;

[0027] See Table 2 for the nutrient levels of the forage ration prepared in the control experiment.

Abstract

Herbage feed for producing pork having high linolenic acid and linoleic acid contents is disclosed and belongs to the field of pig feed. The feed is mainly prepared from, by weight, 50-75% of corn, 9-17% of soybean meal, 5-30% of alfalfa meal, 0-7% of soybean oil, 0.2-1.0% of mountain flour, 0-0.4% of calcium monohydrogen phosphate, 0.4% of table salt, 0.2-0.4% of lysine, 0-0.12% of methionine, 0-0.1% of threonine, 0.02% of tryptophan and 1.0% of a premix. The feed is capable of maintaining and promoting normal growth and development of growing and fattening pigs, saving protein feed, increasing economic benefit, reducing drop loss, and increasing contents of essential amino acid and flavor amino acids and contents of linoleic acid, alpha-linolenic acid, beta-linolenic acid and other unsaturated fatty acids in pork. Meat of the growing and fattening pigs raised by using the feed is fine, tender, juicy, good in taste and high in nutrition value and can be popularized as high-grade pork in the market. The feed is characterized in that 20% of the alfalfa meal is added, the lean meat rate is increased by 7.99% and the thickness of backfat is reduced by 6.72%.

Description

technical field [0001] The invention belongs to the field of pig feed, and in particular relates to a forage ration for producing pork with high linolenic acid and linoleic acid. Background technique [0002] my country is the largest pork producer in the world, and its pork output accounts for about 50% of the world's total output. In recent years, my country's grain-consuming animal husbandry has developed rapidly, the conflict between humans and pigs competing for grain, shortage of feed resources, and low feed utilization have become the main reasons restricting the development of my country's pig industry. In addition, about 60% of the cost of pig breeding in my country comes from feed, which leads to feed and feed additives largely affecting the quality of pig products and the safety of animal-derived food. In order to increase the growth rate of pork and feed remuneration, the abuse of antibiotics and chemical synthetic drugs on the market not only seriously exacerba...
