{"title":"Effects of Metabolizable Energy Intake and Body-Weight Restriction on Layer Pullets: 1-Growth, Uniformity, and Efficiency","authors":"Thiago L. Noetzold, Jo Ann Chew, Douglas R. Korver, René P. Kwakkel, Laura Star, Martin J. Zuidhof","doi":"10.3390/poultry2040036","DOIUrl":"https://doi.org/10.3390/poultry2040036","url":null,"abstract":"This study aimed to determine the effects of dietary energy and body-weight (BW) restriction on layer pullets’ growth, uniformity, and feed efficiency. Two experiments were conducted using a precision feeding (PF) system (Experiment 1) and a conventional feeding (CON) system (Experiment 2). Experiment 1 consisted of a 2 × 4 factorial arrangement (eight treatments) with two feed allocation (FA) levels: meal every visit (MEV) or restricted to the lower boundary of Lohmann Brown-Lite pullets; and three dietary metabolizable energy (ME) levels: Low, Standard (Std), and High (2600, 2800, and 3000 kcal/kg, respectively); the fourth treatment enabled birds to choose from the three diets (Choice). Experiment 2 consisted of a 2 × 3 factorial arrangement (six treatments): two FA levels (ad libitum or restricted) and three dietary ME levels (Low, Std, and High). In each experiment, BW, coefficient of variation (CV), average daily feed intake (ADFI), average daily metabolizable energy intake (MEI), and feed conversion ratio (FCR) were recorded. Diet ADFI preferences and feeding motivation were determined only in the PF experiment. ANOVA was conducted on each experiment with the two main effects as fixed factors (FA and dietary ME), and age or period as the sources of variation. Differences were reported at p ≤ 0.05. MEV (PF experiment) and ad libitum-fed (CON experiment) pullets had greater BW compared to restricted-fed pullets (p < 0.05). The lowest CV was observed in the restricted-fed pullets from the PF experiment (p < 0.05). ADFI was greater in pullets fed the Low ME diet in the PF experiment compared to all the other groups, and the lower the dietary ME, the greater the ADFI in the CON experiment (p < 0.05). Choice-feeding pullets preferred feed with greater ME content in the PF experiment (p < 0.05). The lower the dietary ME, the greater the FCR in the CON experiment (p < 0.05). Restricted-fed pullets had greater daily visits, and lower daily meals, meal size, and successful visits to the PF system (p < 0.05). In conclusion, the results of this trial indicated that lower dietary ME increased FCR and ADFI, whereas feed restriction decreased BW and increased feeding motivation. Future steps after this trial will include examining the effects of dietary energy and feed restriction on carcass composition and sexual maturation.","PeriodicalId":24003,"journal":{"name":"World's Poultry Science Journal","volume":"40 20","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136348327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The treatments comprised control rations of corn and soybean meal and rations to which 500 mL/t and 1000 mL/t of cellulase were added. A total of 180 male broiler chickens were used, distributed in a completely randomized design, with three treatments and six replicates. Broiler chicken performance was monitored during the period from 1 to 21 days old. Significant effects were detected for digestibility only between four and seven days old, when a reduced dry matter nitrogen intake was recorded, and for nitrogen digestibility in the broilers fed cellulase-supplemented rations at a dose of 1000 m/L. Among the analyzed digestive organs, only the biometrics of the large intestine were affected significantly at seven days old. The absolute weights of the liver and pancreas and the activities of amylase, alkaline phosphatase, and transaminases were not affected significantly, indicating that cellulase did not affect the metabolism of these organs. No significant effect was detected in the serum for electrolytes, total protein, or alkaline phosphatase. So, the addition of liquid cellulase produced by Humicola grisea did not affect performance and metabolism in 21-day-old broiler chickens.","PeriodicalId":24003,"journal":{"name":"World's Poultry Science Journal","volume":"45 26","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136347775","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: 480 Japanese quail breeders were distributed in a completely randomized design with five treatments and twelve replications of six females and two males each. A control diet (25 mg/kg VE) and four diets supplemented with TFE (3 g/kg) and VE (25, 100, 175, or 250 mg/kg) were used. Fresh yolk samples and the yolk sac and liver from embryos (11 and 15 days) and chicks (hatch and 3 days) were analysed. Data were subjected to ANOVA, a regression linear model, and contrast tests and the level of significance was set at p < 0.05. Results: TF and VE in the maternal diet improved the amount of alfa-tocopherol and total carotenoid content in the yolk. TFE + VE reduced lipid peroxidation and improved the oxidative status in the fresh yolk, in the embryo and chick yolk, and in the liver. Liver superoxide dismutase activity in hatched chicks increased linearly with the VE level and was not altered by TFE. Maternal diets did not influence progeny performance (1 to 28 days) or the relative expression of superoxide dismutase or glutathione peroxidase genes in the liver of chicks. Conclusions: TFE is an effective antioxidant in fresh eggs and supplementation of 3 g/kg TFE and high levels of VE in quail breeders improves the oxidative status of embryos and newly hatched chicks.","PeriodicalId":24003,"journal":{"name":"World's Poultry Science Journal","volume":"7 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135266482","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
