摘要
本研究旨在探讨北京鸭4-21 d不同相对湿度(RH)对其42 d体况的影响。将48只北京鸭随机分为4个处理(A:RH60 %,B:RH67 %,C:RH74 %,D:RH81 %),每个处理3个重复,每个重复4只鸭。从 4 天到 21 天采用不同的湿度处理。42 d时,4组鸭的体重(BW)、平均日增重(ADG)、平均日采食量(ADFI)和饲料转化率(FCR)均无显著差异(P > 0.05)。D 组的斜体长明显高于 A 组(P < 0.05)。与 A 组相比,其他组的胸深明显增加,B 组和 C 组的腹脂重明显增加(P < 0.05)。C 组和 D 组的肝脏重量和肝脏指数明显高于 B 组(P < 0.05)。B 的腹脂比明显高于 A(P < 0.05)。D 的胆固醇(CHOL)明显高于 A 和 C(P < 0.05),C 的甘油三酯(TG)明显高于 A 和 B(P < 0.05),B 的低密度脂蛋白胆固醇(LDL-C)明显高于 A、C 和 D(P < 0.05)。B 的 pH 值明显高于 A(P < 0.05),A 的亮度(L*)明显高于 B 和 C(P < 0.结果表明,育雏期环境相对湿度对鸭的生产性能没有影响,但会引起一些氧化应激损伤和肉质变化。此外,育雏期接受不同相对湿度处理的鸭子在成熟后对相同环境的适应性也不同。
The influence of relative humidity during the first 21 days post-hatch on the production performance, biochemical indices, and meat quality of Pekin ducks.
This study aims to investigate the effects of different relative humidity (RH) during 4-21d of Beijing ducks on their condition at 42 d. A total of 48 Pekin duck were randomly allotted into 4 treatments (A:RH60 %, B:RH67 %,C:RH74 %,D:RH81 %), each having 3 replicates of 4 ducks. Different humidity treatments were applied from 4 to 21 days. At 42 d, there were no significant differences (P > 0.05) in body weight (BW), average daily gain (ADG), average daily feed intake (ADFI), and feed conversion ratio (FCR) among the 4 groups. Oblique body length in D was significantly higher than that in A (P < 0.05). Compared with A, the chest depth of the other groups was significantly increased, and the abdominal fat weight of B and C was significantly increased (p < 0.05). Liver weight and liver index in C and D significantly higher than that in B (p < 0.05). Abdominal fat ratio in B was significantly higher than that in A (P < 0.05). Cholesterol (CHOL) in D was significantly higher than that in A and C (P < 0.05), triglyceride (TG) in C was significantly higher than that in A and B (P < 0.05), and low-density lipoprotein cholesterol (LDL-C) in B was significantly higher than that in A, C, and D (P < 0.05). pH in B was significantly higher than that in A (P < 0.05), brightness (L*) in A was significantly higher than that in B and C (P < 0.05), redness (a*) in B and C was significantly higher than that in A and D (P < 0.05), and yellowness (b*) in C was significantly lower than that in A and D (P < 0.05).The results indicate that the RH of environment during the brooding period has no impact on duck production performance but induces some oxidative stress damage and changes in meat quality. Additionally, ducks subjected to different RH treatments during the brooding period exhibit varying adaptability to the same environment as they mature.
期刊介绍:
First self-published in 1921, Poultry Science is an internationally renowned monthly journal, known as the authoritative source for a broad range of poultry information and high-caliber research. The journal plays a pivotal role in the dissemination of preeminent poultry-related knowledge across all disciplines. As of January 2020, Poultry Science will become an Open Access journal with no subscription charges, meaning authors who publish here can make their research immediately, permanently, and freely accessible worldwide while retaining copyright to their work. Papers submitted for publication after October 1, 2019 will be published as Open Access papers.
An international journal, Poultry Science publishes original papers, research notes, symposium papers, and reviews of basic science as applied to poultry. This authoritative source of poultry information is consistently ranked by ISI Impact Factor as one of the top 10 agriculture, dairy and animal science journals to deliver high-caliber research. Currently it is the highest-ranked (by Impact Factor and Eigenfactor) journal dedicated to publishing poultry research. Subject areas include breeding, genetics, education, production, management, environment, health, behavior, welfare, immunology, molecular biology, metabolism, nutrition, physiology, reproduction, processing, and products.
