[0058] Test design

[0059] Randomly divide 1,000 1-day-old Peking ducks into 60 pens with controllable environmental temperature, and feed 20 ducks in each pen. The size of each pen is 200cm×120cm×40cm. The feeding period is 21 days. The routine diet of Peking ducks in the early growth stage. At the age of 21 days, select 300 healthy Peking ducks with the same weight and size, and randomly divide the selected 300 21-day-old Peking ducks into 5 treatment groups, each treatment group has 6 repetitions, and each repetition has 10 ducks , the feeding period is 21 days old to 42 days old; 5 treatment groups adopt respectively the meat duck low-protein diet in embodiment 1,2 and control example 1,2,3 to feed;

Abstract

The invention provides low-protein daily ration for meat ducks and application of the low-protein daily ration. The meat duck low-protein daily ration comprises the following raw materials in parts byweight: 137.2-155.8 parts of soybean meal, 721.2-751.8 parts of corn, 44-56 parts of rapeseed meal, 8-12 parts of soybean oil, 14.8-15.7 parts of calcium hydrophosphate, 11.4-11.6 parts of stone powder, 9.5-10.5 parts of a premix, 2.8-3.2 parts of salt, 9.6-12.9 parts of a compound amino acid and 0.9-1.1 parts of a compound enzyme preparation; the meat duck low-protein daily ration can meet various nutritional requirements of meat duck growth, and the crude protein content in the meat duck daily ration is effectively reduced; besides, the nitrogen content in the meat duck manure is effectively reduced, full utilization of nutritional ingredients of daily grain seeds of meat ducks is achieved, the utilization rate of the meat duck feed is increased, and pollution to the environment due tothe fact that the nitrogen element in the meat duck manure is too high is reduced.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a low-protein ration for meat ducks and an application thereof. Background technique [0002] China is the largest waterfowl breeding country in the world, and the waterfowl industry has grown rapidly. It has gradually become an important pillar of the rural economy and farmers' income. According to the survey data of the national waterfowl industry technology system, China produced more than 3.8 billion meat ducks in 2018, and the output of duck meat exceeded 7.5 million tons, accounting for about one-third of the total poultry meat. But along with the fast development of meat duck industry, the environmental pollution that meat duck breeding causes is more and more serious. Chinese meat ducks produce more than 30 million tons of excrement every year, and these excrements cause serious pollution to the ecological environment around the farm. How to effectively reduce the discharg...
