Embodiment Construction

[0015] In this experiment, a single factor design was adopted, and 240 healthy, long-weaned piglets (half male and female) were selected and randomly divided into 4 treatments, each treatment had 6 repetitions, and each repetition had 10 piglets. The pre-feeding period was 4 days, and the test period was 20 days. The test diet was formulated according to the nutritional requirements of pigs in the US NRC (2012). Record the food consumption of each group and the number of each repeated diarrhea head every day. During the experiment, the feeding management procedures and immunization procedures were carried out according to the conventional commercial pig feeding management manual.

[0016] Sample collection and storage Feces collection: adopt the full collection feces method, 3 days before the end of the test, collect feces at 06:30 every day, collect samples according to a certain proportion, put them into sample bags in time, and store them in a refrigerator at -20°C.

Abstract

The invention discloses a suckling pig feed capable of reducing discharge of heavy metals in excrement and preventing diarrhea. The suckling pig feed comprises the following components by weight percent: 60.5% of corn, 16% of soybean meal, 10% of extruded soybeans, 3.5% of fish meal, 4% of whey powder, 2% of wheat bran and 4% of premix, wherein every 100g of premix contains 0-16g of calcium citrate, 0-5g of lactic acid type acidifying agent, 0.75-1.25g of enteric zinc oxide, 0.1-0.2g of zinc glycinate, 0.0125-0.025g of copper lysine, 0.125-0.2g of ferrous glycinate and 0.0250-0.0500g of manganese methionine. The suckling pig feed has the advantages that various organic trace elements, enteric zinc oxide and the like contained in the suckling pig feed can help effectively reduce the additive amount of inorganic trace elements in the suckling pig feed, control diarrhea of weaned piglets and promote growth and reduce environmental pollution caused by heavy metal residues in the suckling pig excrement; calcium citrate and the lactic acid type acidifying agent can help reduce the pH values in the stomachs of the suckling pigs; meanwhile, micro-ecology can help maintain normal intestinal floras and reduce diarrhea of the suckling pigs.

Description

technical field [0001] The invention belongs to the field of feed, and in particular relates to a suckling pig feed capable of reducing excrement heavy metal discharge and preventing diarrhea. Background technique [0002] Under the current intensive pig raising conditions, some pig farms or feed production enterprises add a large amount of inorganic high copper, high zinc, high iron and other trace elements to feed pigs in order to control the diarrhea of ​​weaned piglets, promote the growth of weaned piglets and improve the fur. The amount of copper and zinc added has reached or exceeded the minimum poisoning dose of pigs. Except for a small part absorbed by pigs, most of them are discharged into the environment with feces, seriously polluting the natural environment and affecting animal health and livestock product safety. Adding 3000mg / kg high-dose zinc oxide to the diet of weaned piglets can control diarrhea in piglets. However, long-term use of high zinc will destroy ...
