Problems solved by technology

[0003] Ducks have no sweat glands, are covered with feathers, and have poor adaptability to high temperatures. Therefore, in the hot summer every year, intensive duck farmers have to face how to alleviate the appetite caused by high temperature, feed conversion rate, body weight growth rate and production performance. falling problem

Embodiment 1

[0017] Example 1 Linwu duck diet against heat stress

[0018] Formula: 85% compound feed pellets + 15% Twisted Mountain mung bean forage pellets.

[0019] Among them, the neutral detergent fiber content of the compound feed is 27.08wt%, and the acid detergent fiber content is 19.88wt%; the compound feed is the large duck feed pellets specially used by Shunhua Duck Industry;

[0020] The content of neutral detergent fiber and 28.95% of acid detergent fiber is 31.88%.

[0021] Preparation of Mung bean forage granules from Mung bean: After the mung bean grass is mowed, it is dried in the sun, crushed and pressed into forage granules. The particle size is the same as the particle size of compound feed (diameter 4mm, length 12-18mm).

Embodiment 2

[0022] Example 2 Linwu duck diet against heat stress

[0023] Formula: 70% compound feed pellets + 30% Twisted Mountain mung bean forage pellets.

[0024] The rest are the same as in Example 1.

Embodiment 3

[0027] Example 3 Cultivation test

[0028] The Linwu ducks used in the breeding experiment were all 42 days old, male, healthy and basically the same weight.

[0029] Breeding experiments were divided into three treatment groups according to the different ingredients of the feed, namely: (1) full compound feed group; (2) 85% compound feed + 15% forage pellets group; (3) 70% compound feed +30% Forage Pellet Group. Three replicates were set for each treatment group, with 12 ducks in each replicate. The feeding amount of feed is fed according to the internal feeding standard of Shunhua Duck Industry. The animals were fed twice a day at 8:00 in the morning and 5:00 in the afternoon, each lasting 30 min, and the breeding experiment lasted for 28 days.

[0030] The feeding amount and remaining amount of each feed in each duck house were recorded every day during the experiment. On the 5th, 15th, and 25th days of the feeding experiment, one duck was randomly selected from each du...

Abstract

The invention belongs to the field of poultry breeding, and specifically discloses a Linwu duck diet with heat stress resistance and application of desmodium intortum forage grass. The Linwu duck dietwith heat stress resistance comprises 60-90% by weight of a compound feed and 10-40% by weight of the desmodium intortum forage grass. The diet provided by the invention contains desmodium intortum forage grass granules, the decrease of feed intake of Linwu ducks caused by high temperature stress can be effectively alleviated, and the feed intake of the Linwu ducks is no longer sensitive to hightemperature. At the same time, the weight gain of the Linwu ducks in summer can be increased, the feed conversion rate is not improved (the feed conversion rate is not decreased due to addition of theforage grass), the duck meat quality of the Linwu ducks is improved, the content of free amino acids in duck meat is increased, and the diet of the present invention can be used as a reasonable dietfor the Linwu ducks in high temperature summer.

Description

technical field [0001] The invention belongs to the field of poultry breeding, and particularly relates to a heat stress-resistant Linwu duck ration and the application of Xuantuoshan mung bean forage in relieving heat stress of Linwu ducks. Background technique [0002] Poultry is a warm-blooded animal. Once the ambient temperature exceeds its isothermal zone, heat stress will occur, the most obvious of which is to further affect the production performance and health of poultry by reducing feed intake and nutrient metabolism. Slower weight gain, lower egg production, higher mortality, etc. In poultry farming, there are various measures to mitigate the negative effects of heat stress, such as improving ventilation in poultry houses, changing farming methods, and adjusting the supply of nutrients in the diet. [0003] Ducks have no sweat glands and are covered with feathers, so they have poor adaptability to high temperature. Therefore, in the hot summer every year, duck int...
