Description

Technical Field

[0001] This invention relates to the field of feed product technology, specifically to a compound rabbit feed and its preparation method. Background Technology

[0002] my country's rabbit industry began in the 1980s, encompassing multiple sub-sectors such as meat rabbits, fur rabbits, and Angora rabbits, and has now become a major rabbit-raising country globally. my country is also a major consumer of rabbit meat, with an average annual consumption of nearly 400g per person, 12.5% ​​higher than the world average. Compared to other livestock and poultry meat, Chinese-raised meat rabbit meat has unique nutritional advantages of "three highs and three lows": high protein, high lysine, and high phospholipids, and low fat, low cholesterol, and low calories. Therefore, it is widely known as "beauty meat," "brain-boosting meat," and "health-promoting meat," and is one of the key meat varieties advocated for development in the "China Nutrition Improvement Action Plan." Furthermore, meat rabbits have diverse commercial value; in addition to the industrial utilization of their meat, fur, and wool, they can also be sold as pet rabbits and laboratory rabbits, further broadening the channels for economic benefits from rabbit farming.

[0003] The prospects for meat rabbit farming are broad. As a herbivorous animal, its "grass-for-meat" farming model has low costs. At the same time, meat rabbit farming has the advantages of short cycle and quick results. Domestic rabbits are prolific animals with a gestation period of only 28-30 days. They have strong reproductive capacity, fast growth rate, and relatively small investment scale, resulting in a high input-output ratio and significant farming advantages. Summary of the Invention

[0024] Example 6: Rabbit Feed Trial and Results 1. Laboratory animals Domestic rabbits with consistent health status and similar weight (female rabbits weighing 2.5±0.2kg, and meat rabbit kits at 7 days old, weighing 120±10g) were selected. Among them, there were 160 breeding female rabbits (20 randomly assigned to each group) and 240 meat rabbit kits (30 randomly assigned to each group). All rabbits had no history of disease, complete immunization records, and were kept in a uniform and standardized environment.

[0025] 2. Experimental Feed Experimental group: The feed of this invention (containing antimicrobial peptides and a variety of natural ingredients, with a nutritional ratio that meets the needs of high-density breeding and meat rabbit growth); the feed particle size, feeding method, and feeding amount are consistent, and water is available freely.

[0026] 3. Test conditions The experimental site was a standardized rabbit hutch, with the temperature controlled at 18-25℃, humidity at 60-70%, and light at 12h / day. Breeding does were raised in a high-density breeding mode (each does reproduce once every 35 days, with a stocking density of 3 rabbits / m²), while meat rabbits were raised at a conventional large-scale stocking density (10 rabbits / m²). The experimental period consisted of two breeding cycles (70 days) for does and a 60-day growth cycle for meat rabbits (from 7 days to 67 days old).

[0027] 4. Measurement Indicators and Methods Nutritional requirements and kit survival rate: Record the number of kits born to the doe, the number of kits that survived the birth, and the number of kits weaned (at 28 days of age). Calculate the kit survival rate (number of weaned kits / number of kits that survived the birth) × 100%. Measure the milk production of the doe during the experiment (measured once every 5 days, and the average milk production was calculated).

[0028] Meat rabbit growth and feeding costs: Record the initial weight and final weight of meat rabbits in the experiment, and calculate the average daily weight gain (final weight - initial weight) / number of days in the experiment.

[0029] Immune function: On days 30 and 60 of the experiment, 10 rabbits were randomly selected from each group, and serum was collected to measure the levels of immunoglobulins IgG and IgA (enzyme-linked immunosorbent assay). The incidence of disease in the rabbit population during the experiment was recorded (number of sick rabbits / total number of rabbits × 100%) and the incidence of stress response (number of rabbits exhibiting stress symptoms such as lethargy and loss of appetite / total number of rabbits × 100%). 5. Test Results

[0030] The feed of this invention can quantitatively meet the comprehensive nutritional needs of high-density breeding does, significantly improve the survival rate of kits, accelerate the growth rate of meat rabbits, effectively improve breeding efficiency, and at the same time significantly enhance the immune function of rabbit groups, reducing the incidence of disease and stress response.
