[PMID: 38255668 PMCID: PMC10817457 DOI: 10.3390/life14010053] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2023] [Revised: 12/12/2023] [Accepted: 12/22/2023] [Indexed: 01/24/2024] Open
Abstract
The purpose of the study was to investigate the effects of dietary hempseed or camelina cakes on the fatty acid profiles of intramuscular fat in quail. A total of 189 one-day-old quail were allocated to three dietary treatment groups. The diet of the control (C) group was supplemented with 10% rapeseed cake, whereas the rapeseed in experimental 1 (HE) and experimental 2 (CA) groups was replaced by, respectively, hempseed cake and camelina cake in the same proportions. The length of the study was 42 days. Dietary enrichment with camelina cake increased the α-linolenic fatty acid (ALA) content in the meat of CA group 2.5 times (p < 0.01). The muscle tissues of CA contained 3.4-3 times more eicosapentaenoic acid (p < 0.01), 1.2 times more docosapentaenoic acid (p < 0.05-p < 0.01) and 1.3 times more docosahexaenoic acid (p < 0.01) and, thus, demonstrated the increase in total long chain (LC) n-3 polyunsaturated fatty acids (PUFA) (p < 0.01) and total n-3 PUFA (p < 0.01) compared with the C group. The ALA and total n-3 PUFA content in the breast and leg meat of HE-treated quail were, respectively, 1.3 and 1.1 times higher (p < 0.01) than in the C group but the accumulation was lower compared to the CA group. The content of γ-linolenic acid was found to be 1.21-1.31 times higher in HE quail meat (p < 0.01). However, hempseed cake supplementation had a negative effect on growth performance. The supplementation of quail feed with camelina or hempseed cakes resulted in the production of healthy meat with an increased n-3 PUFA content.

Potential of Full-Fat Silkworm-Based Diets for Laying Quails: Performance and Egg Physical Quality. Animals (Basel) 2023; 13:ani13091510. [PMID: 37174547 PMCID: PMC10177170 DOI: 10.3390/ani13091510] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2023] [Revised: 04/21/2023] [Accepted: 04/27/2023] [Indexed: 05/15/2023] Open
Abstract
The present research was conducted to determine the optimal inclusion level of full-fat silkworm chrysalis meal (SWM) into laying quails' diets, focusing on performance traits and egg physical quality. A total of 240 31-day-old female Japanese quails were randomly assigned to four dietary groups (12 replicates/treatment; 5 quails/replicate); quails were initially fed a standard commercial diet for pullets until 63 days of age. When oviposition started, the experimental groups received the following diets: a conventional corn and soybean-based diet (control diet-C) and three other diets, including 4%, 8%, or 12% of full-fat SWM (SWM4, SWM8, SWM12, respectively). Experimental diets were provided until quails reached 119 days of age. Birds displayed satisfactory productive performance throughout the trial. SWM12 and SWM8 had higher (p < 0.001) egg production but also a higher feed conversion ratio compared to C. At the end of the trial, the eggs edible portion increased, and shell weight decreased with increasing the SWM dietary inclusion level (p < 0.001). At the same time, SWM12 displayed an increase in albumen pH (p < 0.05), even though in the normal range for quail egg. Overall, full-fat SWM (up to 12%) can be considered a promising feed ingredient for laying quails, although higher inclusion levels (>8%) require special attention because SWM also contains anti-nutritional factors.
