Abstract
Description
Technical Field
[0001] The invention relates to the technical field of feed processing, in particular to a mixed feed of fresh edible leaf grass and whole corn and a preparation method thereof. Background Art
[0002] In recent years, my country's social and economic level has been developing rapidly, and people have higher requirements for pork quality and flavor. Technicians are increasingly eager to study fermented feed to replace antibiotics. It is of great significance to find fermented feed that can resist pig diseases and improve pork flavor quality that meets market demand and pork with low cost and good meat quality.
[0003] These products happen to be the raw materials for making fermented feed, which is a new type of biological feed formed by artificially controlling the degradation of toxic substances in the substrate under the technology of microbial fermentation. Generally speaking, this new type of feed can not only improve the disease resistance of pigs, but also improve the digestion metabolism and muscle quality of pigs, while reducing the incidence of diseases and the use of antibiotics. This can largely alleviate the shortage of feed raw materials and maximize resource utilization, which not only protects the environment, but also complies with my country's sustainable development strategy.
[0004] Research in recent years has found that adding fermented feed can improve the growth performance, muscle quality and digestion metabolism of chickens, cattle, sheep and other livestock and poultry. In subtropical areas, abundant rainfall provides a good environment for the growth of forage, especially for the growth of edible grass. Eating leaf grass is a perennial grass herb with a well-developed root system and tall plants. It is an important forage feed resource in southern my country. It likes warm and humid climates and is suitable for cultivation in tropical and subtropical areas. It is drought-resistant, acid-resistant, lodging-resistant, disease-resistant, and has good adaptability and regeneration. It has a low crude fiber content, a slightly sour taste, and good palatability. It is a favorite of many livestock and poultry and is an important high-quality green forage in the south.
[0005] Therefore, there have been relevant studies on processing edible leaf grass into fermented feed for feeding animals. However, it was found in experiments that the effects of feed fermented by different animals, different forages, different addition amounts, and different fermentation methods on animals are completely different. For this reason, a mixed feed of fresh edible leaf grass and whole corn and a preparation method thereof are proposed to solve the above-mentioned problems. Summary of the invention

[0035] Comparative study on the effect and benefit of feeding whole corn fermentation to growing and finishing pigs:
[0036] Materials and Methods
[0037] 1 Test materials
[0038] Whole corn plant: The whole corn plant is crushed, the fermentation strains are mixed, and the fermentation bags are sealed. The temperature is controlled at 15-25°C. The nutritional components of the fermented corn plant are as follows: dry matter 22.46%; organic matter 19.22%; crude protein 1.90%; crude fat 0.62%; total carbohydrates 16.70%; dry matter-based gross energy 17.87MJ / kg;
[0039] 2 Experimental animals and design
[0040] A single factor experimental design was used to select 12 growing pigs (Songliao Black) with similar body weight (45.34±0.56) kg and randomly divided into two treatments. The control group was fed a basic diet, referring to the nutritional requirements of growing and finishing pigs in NRC (1998); the experimental group, in the 1st to 4th week, 5th to 8th week and 9th to 12th week of the experiment, replaced the basic diet with 55%, 65% and 75% fermented corn whole plant in equal amounts. Detailed diet composition and nutritional level are shown in the table below:
[0041]
[0042]
[0043] 3. Determination indicators and methods:
[0044] The pigs' coat color, feeding and activity status, and diarrhea were observed every day. The experimental diet was photographed at the beginning of each stage. At the end of the 4th, 8th and 12th week of the experiment, the experimental pigs and their morning feces were photographed and compared. Production performance: the pigs' feed intake and residual feed amount were accurately recorded every day, and the average daily feed intake (ADFI) of each pig was calculated. At the beginning and end of each stage: the experimental pigs were weighed on an empty stomach, and the average daily weight gain (ADG) of the pigs was calculated. The wet feed-to-weight ratio (F / G) and the dry matter intake / weight gain ratio (DMI / G) were calculated based on ADFI and ADG.
[0045] Results and Analysis: After adding fermented whole corn to the diet, the water content was higher, the texture was softer, looser, and had a sour aroma. The growth and finishing pigs fed the fermented whole corn diet had less dandruff, improved the pigs' skin color, and increased brightness. The hair was longer and harder. The pigs in the experimental group were slightly longer and narrower in back, while the pigs in the control group were slightly shorter and wider in back. Observation of pig feces showed that the pigs fed the fermented whole corn diet had a higher water content, a shiny texture, a soft texture, no lumps, and no constipation.
[0046] Corn stalks have a high crude fiber level. Fiber has the function of stimulating gastrointestinal development and accelerating the circulation of chyme in the digestive tract. It is an indispensable component of pig feed. The results of this study showed that the fermented whole corn prepared in this study preserved the green and juicy fresh corn. Feeding the fermented whole corn diet achieved the fermented wet feeding of pigs. The high fiber and fermentation metabolites in the diet increased the intestinal health of pigs and caused corresponding changes in feces and appearance. Studies have shown that within a certain range, the low digestible energy (DE) concentration caused by high fiber in the diet can usually meet the DE demand by increasing feed intake through its own physiological regulation. Therefore, in the early stage of the experiment, there was no difference in the weight and daily weight gain of growing and fattening pigs when 55% of fermented whole corn was added. In the later stage of the experiment, due to the increase in the proportion of fermented whole corn in the diet to 65% to 75%, the excessive moisture in the diet limited the dry matter intake of pigs after they were full at the maximum. At the same time, high fiber, low nutrient and energy intake led to reduced nutrient and energy intake, resulting in a lower growth rate. Therefore, the appropriate proportion of fermented whole-plant corn replacement in the diet needs further study.
[0047] In this study, an average of 65% fermented whole corn was used to replace the daily diet of growing and finishing pigs. On the basis of wet feed, the feed intake increased by 2.25 times, but the cost was reduced by 2.98 times. Although the weight gain of pigs fed with fermented whole corn decreased, the reduction in feed costs could exceed the value-added loss due to the slowed growth rate. Therefore, feeding whole corn fermentation to growing and finishing pigs can increase breeding benefits, and growing and finishing pigs can be fed with fermented whole corn.
