The effects of dietary Kigelia pinnata leaf (KPL) on growth, carcass, muscle fatty acids, antioxidant status, cholesterol, physicochemical properties, and sensory profile of Longissimus thoracis et lumburum (LTL) muscle in rabbits are investigated. Seventy-two, 32 d old male New Zealand rabbits (684 ± 18 g) are randomly assigned to diets containing either no KPL (KPL-0), 5% KPL (KPL-5) or 10% KPL (KPL-10) for eight weeks, and euthanized, and the LTL is refrigerated for 6 days. Dietary KPL does not influence growth performance and carcass cuts in rabbits. Abdominal fat is lower in KPLrabbits than in the KPL-0 rabbits. Supplemented LTL has lower intramuscular fat and cholesterol, and higher crude protein, polyphenol content, glutathione reductase, and catalase compared with the control LTL. Concentration of C18:3n-3, C22:6n-3, and C20:5n-3 is higher in supplemented LTL than the control LTL. Supplemented meat has lower cook loss than the KPL-0 meat at 24 h postmortem. The KPL-10 meat has higher redness and lower malondialdehyde content than other meats on d 6 postmortem. Juiciness and overall acceptance of the supplemented meat are higher than that of the KPL-0 meat. Supplementation with KPL-10 enhances muscle n-3 fatty acids, sensorial quality, and oxidative stability of rabbit meat. Practical Applications: Practical applications: Rabbit meat is replete in n-6 polyunsaturated fatty acid (PUFA) but low in n-3 PUFA, which heightens its n-6/n-3 ratio. Higher n-6/n-3 PUFA intake can pose serious health risks to consumers. This suggests a need to ameliorate the n-3 PUFA of rabbit meat. Dietary KPL causes ≈147-184% increase in n-3 PUFA and a 66-77% decrease in n-6/n-3 ratio in rabbit meat. Moreover, KPL improves sensorial quality and oxidative stability and lowers intramuscular fat and cholesterol content of rabbit meat. These results support the delivery of a healthier rabbit meat that responds to consumer demands. This study explicates the potential of KPL in ameliorating the nutritional value and sensory quality of rabbit meat.

Fishmeal (FM) is the main protein source in fish feed. However, it is quite expensive due to its limited resources. Therefore, finding a dietary alternative to the FM to sustain fish production is crucial, and the current study was performed to assess the impact of poultry offal silage (POS) with or without betaine supplementation; as an effective and cheaper alternative to FM; on feed efficiency, growth performance, spleen morphology and intestinal morphometry of Nile tilapia (Oreochromis niloticus) fingerlings. Four dietary treatments were formulated: (1) FM based diet, (2) FM‐B; FM diet +0.7% betaine, (3) POS diet and (4) POS‐B; POS diet +0.7% betaine. Each dietary treatment consisted of three replicates (n = 10/replicate), and the experiment was continued for 16 weeks. By the end of the experiment, spleen and intestine specimens were collected from 15 fish (n = 5/replicate) for histopathological assessment. The results were statistically analysed using GLM procedures of SAS 9.4. Feed efficiency increased in both POS‐B and FM‐B groups (p = 0.01), while body weight and body weight gain showed only weak tendencies towards an increase (p = 0.10 and 0.12, respectively). The villi length was the highest in POS‐B fed group (p < 0.01). In addition, melanomacrophage centres of the spleen increased in both betaine‐supplemented groups (p < 0.01). From our findings, we conclude that betaine supplementation with poultry offal silage improved production performance and immune status of Nile tilapia fish.

“…5% of total body) and have long been an ideal model for investigating BAT development and functions ( Hardman et al, 1971 ; Harris et al, 1986 ; Comeglio et al, 2018 ). The abundant BAT might be a factor that keeps rabbits lean and enables rabbits to yield low-fat meats ( Abdelatty et al, 2021 ). Naturally, the classical BAT of rabbits losses its thermogenic phenotype during the growth period ( Derry et al, 1972 ).…”

Brown adipose tissue (BAT) represents a valuable target for treating obesity in humans. BAT losses of thermogenic capacity and gains a “white adipose tissue-like (WAT-like)” phenotype (BAT whitening) under thermoneutral environments, which could lead to potential low therapy responsiveness in BAT-based obesity treatments. However, the epigenetic mechanisms of BAT whitening remain largely unknown. In this study, BATs were collected from rabbits at day0 (D0), D15, D85, and 2 years (Y2). RNA-sequencing (RNA-seq) and the assay for transposase-accessible chromatin with high-throughput sequencing (ATAC-seq) were performed to investigate transcriptome and chromatin accessibility of BATs at the four whitening stages, respectively. Our data showed that many genes and chromatin accessible regions (refer to as “peaks”) were identified as significantly changed during BAT whitening in rabbits. The BAT-selective genes downregulated while WAT-selective genes upregulated from D0 to Y2, and the de novo lipogenesis-related genes reached the highest expression levels at D85. Both the highly expressed genes and accessible regions in Y2 were significantly enriched in immune response-related signal pathways. Analysis of different relationships between peaks and their nearby genes found an increased proportion of the synchronous changes between chromatin accessibility and gene expression during BAT whitening. The synergistic changes between the chromatin accessibility of promoter and the gene expression were found in the key adipose genes. The upregulated genes which contained increased peaks were significantly enriched in the PI3K-Akt signaling pathway, steroid biosynthesis, TGF-beta signaling pathway, osteoclast differentiation, and dilated cardiomyopathy. Moreover, the footprinting analysis suggested that sequential regulation of potential transcription factors (TFs) mediated the loss of thermogenic phenotype and the gain of a WAT-like phenotype of BAT. In conclusion, our study provided the transcriptional and epigenetic frameworks for understanding BAT whitening in rabbits for the first time and might facilitate potential insights into BAT-based obesity treatments.
