Problems solved by technology

[0004] There are very few domestic and foreign literatures on the research and application of low-protein diets in meat duck diets. Only Zhang Huihua et al. 15-44 days of age, reducing dietary crude protein by 1.5 percentage points) and adding different sources and levels of methionine have no significant effect on the growth performance of "Xianhu" meat ducks, and there is no low-protein diet in Beijing duck diets. research report

Embodiment Construction

[0012] The following examples are intended to illustrate rather than limit the invention.

[0013] Taking Peking duck as the test object, adopting the ideal amino acid pattern of Peking duck disclosed in the present invention, and referring to the nutritional requirements standard of Peking duck (NRC, 1994) for other nutritional requirements, when keeping the total amount and ratio of dietary amino acids and other nutritional levels unchanged 1 to 2 percentage points of crude protein in Peking duck diets, that is, from 20% (control group) to 19% (test group 1) and 18% (test group 2) at 1 to 14 days of age, respectively. ); the dietary crude protein was reduced from 18% (control group) to 17% (test group 1) and 16% (test group 2) from 15 to 42 days of age. The control group, test group 1 and test group 2 each set up 5 repetition groups, and each repetition group had 30 Peking ducks, which were fed for 42 days. The ideal amino acid pattern and dietary crude protein and amino aci...

Abstract

The invention discloses an ideal amino acid mode of south peking duck and application thereof in low-protein daily ration. The ratios of lysine to methionine to sulphur amino acid to threonine to tryptophan in the ideal amino acid modes for 1-14-days-old south peking ducks and 15-42-days-old south peking duck are 100:45:76:70:22 and 100:48:86:75:20 respectively. According to the ideal amino acid mode of the south peking duck disclosed by the invention, the protein level in the daily ration of the peking duck can be reduced by 1% to 2% so as to achieve the aims of maintaining the growth performance and reducing the nitrogen content in the excrement.

Description

technical field [0001] The invention belongs to the field of animal nutrition, and in particular relates to an ideal amino acid pattern of a southern Peking duck and its application in low-protein diets. Background technique [0002] The nutrition of protein is essentially the nutrition of essential amino acids and non-essential amino acids. Ideal protein means that the amino acid composition and ratio of protein in feed are consistent with the amino acid composition and ratio of protein required by animals. The ideal protein amino acid pattern mainly includes two patterns based on total amino acids and digestible amino acids. At present, the research on the ideal protein amino acid pattern at home and abroad mainly focuses on pigs and broilers, and there are few studies on Peking duck. Hou Shuisheng et al. (2005) reported that the ideal pattern of Peking duck 1-14 days old and 15-35 days old lysine: methionine: sulfur-containing amino acid: threonine: tryptophan is 100:46:7...
