Cassava residue biological fodder for pig fattening and preparation method thereof

Abstract

The invention discloses cassava residue biological fodder for pig fattening. The cassava residue biological fodder for pig fattening is prepared from the following three pig fodder formulas in three weight ranges of 28-50 kg, 50-75 kg and 75-100 kg. The invention further discloses the formulas and a preparation method. According to the cassava residue biological fodder for pig fattening, the formulas and the preparation method, cassava residues are adopted as a raw material of the fodder, raw material cooperation is scientific and reasonable, the fodder is high in palatability, pig feeding ispromoted, the nutrition requirements of a pig fattening stage are met, the pig disease resistance and the lean meat yield can be improved, a feed conversion ratio reaches (2.2 to 2.9) to 1, the morbidity of pigs is reduced, and the growth performance of the pigs can be improved; after the pigs eat the fodder, the fodder utilization efficiency is high, resources are saved, and pig meat does not contain the fattening stage fodder, so that the pig meat product quality is guaranteed; compared with ordinary fodder, the cassava residue biological fodder for pig fattening has the advantage that the profit of each fattening pig is improved by 100-125 yuan.

Description

technical field [0001] The invention belongs to the technical field of livestock feed production, in particular to a cassava residue biological feed for pig fattening and a preparation method thereof. Background technique [0002] my country's animal husbandry is developing rapidly, and the stock of livestock and poultry and the annual output of livestock and poultry products are increasing year by year, so the demand for feed is also increasing year by year. The total output of feed in my country has increased from 137 million tons in 2008 to 194 million tons in 2012, an increase of 41.6%. However, with the development of my country's economy and the advancement of urbanization, the area of ​​cultivated land in our country is decreasing year by year. In 2012, my country's cultivated land area was 1.826 billion mu, which was close to the red line of cultivated land (1.8 billion mu) stipulated by the state in 2007. In short, the shortage of feed raw materials in my country ...

Problems solved by technology

Secondly, cassava with high hydrocyanic acid has a bitter taste, which often causes discomfort, anorexia, and even nausea and vomiting in animals.

Thirdly, when more cassava is added to the feed and the pelleting temperature is high, it is easy to make the feed stick into agglomerates, which affects the pelleting process of the pellets.

[0005] At present, there are three stages in the fattening stage of pigs: the early stage, the middle stage, and the late stage. The nutrients required for each stage of growth are different. However, there is no relevant feed for different stages of fattening pigs on the market. Pig fattening feed products are all the same, however, the growth needs of animals is a real-time variable amount, especially the most obvious change with growth, so it cannot provide reasonable nutritional requirements for pigs, resulting in less or no weight gain of pigs Increase, some even do not increase but decrease, the growth rate is slow, and the feeding time is long, which increases the feeding cost

Moreover, due to the constraints of pig breeding space, environment, captive breeding methods and captive breeding conditions, the chances and risks of pigs being infected with various bacteria, viruses, parasites and mycoplasma diseases have increased, resulting in a reduction in the benefits of large-scale pig breeding and a decrease in the cost of farming for farmers. Increase

The abuse of antibiotics and other drugs, on the one hand, causes bacteria and viruses to develop drug resistance; on the other hand, it causes drug residues, which brings about the safety of animal food

In addition, the combination of feed is unreasonable, resulting in excessive nutrient excretion of fattening pigs, which wastes resources and adds a lot of burden to the breeding environment. More importantly, the finished pig meat also contains feed during the finishing period, which seriously aggravates The decline in the flavor and quality of pork has seriously endangered human health, and also caused hidden dangers in food safety, causing consumers to panic about the quality of pork
