Description

A full-price compound feed for improving the quality of blue fox fur

technical field

The invention relates to a complete compound feed.

Background technique

The blue fox is a precious fur animal belonging to the order Canidae Carnivora. It mainly feeds on high-protein and high-fat animal feed. Up to now, how to scientifically and rationally match feed, reduce feed cost, and make all nutritional indicators meet the growth needs of blue foxes is an urgent problem to be solved. The production performance and fur quality of the blue fox are mainly affected by the nutritional level of the diet. Among them, the fat content accounts for a relatively high proportion in the fur animal feed, which provides the fat requirement suitable for the growth of the blue fox, which can meet its energy demand and increase protein. utilization efficiency.

At present, the effects of different nutritional levels of energy and protein combinations, enzyme preparations, and prebiotics on blue foxes have been studied at home and abroad, but the effects of different fat contents on the growth performance, fat metabolism, fat-related gene expression and fur quality of blue foxes have been studied. There are few studies, with mixed results.

Feed composition and nutritional level (air-dried basis)% of each embodiment scheme of table 1

The forage prepared in Examples 1 and 2 and Comparative Experiment 1 and 2 was fed to blue foxes and related tests were carried out, specifically as follows:

1. Blue fox feeding and management

The test base is Nehe Boruite Blue Fox Breeding Co., Ltd. Clean and disinfect cages, food boxes, sinks, etc. before the test. During the test period, blue foxes were reared in single cages with a size of 1.00m×0.70m×0.80m. Feed once a day at 7:00 am and 5:00 pm, feed freely, let each fox eat enough and drink water freely. The experimental period was uniformly carried out outdoors under natural light, and was raised by fixed breeders to eliminate the influence of different external environments and management on the experimental blue foxes. Clean sinks and food troughs daily. Disinfect the test site regularly, carry out epidemic prevention for the test blue fox, and set up disinfection facilities at the door. Observe the conditions of the blue foxes in each group every morning and evening, observe whether the food intake and drinking water are normal, and whether the feces are abnormal, etc., and make records on the day.

2. Detection indicators and detection methods

2.1 Determination of growth performance indicators

At the age of 18 weeks, the blue fox was weighed on an empty stomach before the morning feeding at the end of the early breeding period. After that, at the age of 26 weeks, the blue fox was weighed on an empty stomach before the morning feeding at the end of the winter hair period, and recorded as the final weight of the winter hair period. The body weight of the experimental foxes in the winter fur period was changed, and the feed consumption was calculated.

Average daily gain (g/d) = (weight at the end of the stage - weight at the beginning)/days of the test;

Average daily feed intake (Average daily feed intake, g) = total feed intake for each stage/test days;

Feed to meat ratio (Feed/Gain, %) = average daily feed intake/average daily weight gain;

Metabolizable energy/Gain (MJ/kg) = average daily metabolizable energy/average daily gain

2.2 Determination of nutrient apparent metabolic rate index

At the age of 26 weeks, that is, the end of the winter hair period, 6 healthy blue foxes with normal food intake and defecation were randomly selected in each group as the digestion and metabolism test animals (consistent with the blue foxes in the growth index test). The metabolism test adopts the method of collecting feces. During the test period, the blue foxes are free to eat and drink, and the feed intake is accurately recorded every day. After weighing the excrement collected every day, add 10% of the fresh weight to 10% hydrochloric acid solution and mix well, and store it at -20°C. The urine collected every day and the mass The 10% hydrochloric acid solution was mixed thoroughly at a volume ratio of 50:1, stored at -20°C, and collected continuously for 3 days. After all the experiments were completed, the excrement and urine collected from the same group were fully mixed and stored at -20°C for later use; when the experimental blue fox was 26 weeks old, that is, at the end of the winter hair period, the sample collection method for the digestion and metabolism test was the same as that in the early breeding period. same. The feeding management during the digestion and metabolism test was exactly the same as the daily feeding management. About 100g of feces samples were selected from each group for the preparation of air-dried samples. The selected feces samples were first dried in an oven at 120°C for 15 minutes to inactivate the enzyme activity, and then dried at 65°C. Prepare samples to be tested. Crude protein content was determined by the Kjeldahl method.

Adopt Kjeldahl method, weigh air-dried feces sample 0.2g, be accurate to 0.0001g, pour into the bottom of digestion tube without loss, add mixed catalyst (copper sulfate: the mass ratio of sodium sulfate is=1:15) 3.2g, Then add 10 mL of concentrated sulfuric acid with a mass percentage of 98%, and let stand overnight. The next day, heat on the digestion electric furnace at 260°C for 40 minutes, then raise the temperature of the digestion furnace to 410°C and heat for 30 minutes until the digestive juice becomes transparent, leave the digestion furnace at the end, place it in the fume hood until no gas escapes from the digestion tube, and cool down Afterwards, the crude protein content was determined directly using an automatic protein analyzer (KT-2300, FOSS).

Nitrogen deposition (g/d) = ingested nitrogen - fecal nitrogen - urine nitrogen;

Net protein utilization rate (%)=(nitrogen deposition/ingested nitrogen)×100;

Protein biological titer (%)=[nitrogen deposition/(ingested nitrogen-fecal nitrogen)]×100.

2.3 Sample collection and processing

After the end of the whole test period, six blue foxes were selected in each group, and 2 hours after eating, they were killed by electric shock. After the killing, the blue foxes were measured by the farm professionals for their body length (from the tip of the nose to the root of the tail), and then the skin was taken. A series of primary processing processes, skilled technology, to avoid the impact of human factors on the quality of fur.

Skin length: measure the distance (cm) from the tip of the fox fur to the base of the tail;

Needle villi length: Take 3 points (neck, mid-back, and sacrum) on the midline of the back of each fox fur, separate the fur along the midline and insert it into a thin steel ruler with a scale to measure its length (cm);

Needle hair fineness: put the wool sample flat on a glass slide and fully expand it, cover it with another glass slide, seal the two ends with adhesive tape, measure the diameter of the needle hair and fluff with an eyepiece micrometer under an optical microscope ( μm), and then compared.

Fur grade identification: Hire fur animal experts to evaluate and grade the fur quality according to the maturity, luster, smoothness of needle hair, thick undercoat, and fur color or clarity.
