“…The benefits of fasting has been demonstrated in the dietary practices of numerous livestock animal species. The utilization of intermittent fasting as a feeding strategy for chickens is widely acknowledged for its capacity to improve flock uniformity by increasing portion sizes, thereby prolonging feeding periods and reducing feed competition (Lindholm, 2019 ; Lindholm and Altimiras, 2023 ). The incorporation of fasting as a pre-slaughter practice for pigs has the potential to enhance carcass hygiene (Faucitano et al, 2010 ), pork quality, and animal welfare (Driessen et al, 2020 ).…”

Guinea pigs have historically been used as a food source and are also an important model for studying the human intestines. Fasting is the act of temporarily stopping the intake of food. This process can alter the microbiota of various animals. This study is the first to investigate the impact of fasting on the cecum microbiome of three guinea pig breeds. We investigated the impact of fasting on the microbiome population structure in the cecum of three guinea pig breeds. This was done by sequencing and analyzing the V4 hypervariable region of the 16S rRNA gene in bacterial communities found in cecum mucosa samples. To achieve this, we established two treatment groups (fasting and fed), for each of the three guinea pig breeds: Andina, Inti, and Peru. The study involved twenty-eight guinea pigs, which were divided into the following groups: Andina-fed (five), Andina-fasting (five), Inti-fed (four), Inti-fasting (five), Peru-fed (five), and Peru-fasting (four). The results indicated a significant difference in beta diversity between the treatment groups for the Peru breed (P-value = 0.049), but not for the treatment groups of the Andina and Inti breeds. The dominant phyla across all groups were Firmicutes and Bacteroidetes. We observed variations in the abundance of different taxa in the cecum microbiota when comparing the treatment groups for each breed. Additionally, there was a higher number of unique taxa observed in the fasting groups compared to the fed groups. We discovered that the genus Victivallis was the only one present in all fasting groups across all breeds. Despite the findings, the resilience of the gut microbiome was not challenged in all three breeds, which can lead to disruptive changes that may affect the overall maintenance of the cecum microbiome. Based on the observed differences in the treatment groups of the Peru breed, it can be suggested that fasting has a greater impact on this particular breed.

The current study aimed to optimize the fasting duration in order to mitigate the detrimental effects of heat stress on broilers raised in hot and humid climatic environments. A total of 500 broiler DOCs were assigned to five distinct treatment groups: T0= Non-fasted controlled temperature (24-26 oC) (NF-CT), T1= Non-fasted heat stressed (30-38 oC) (NF-HS), T2= 6 hours fasted heat stressed (6-h FHS), T3= 8 hours fasted heat stressed (8-h FHS), and T4= 10 hours fasted heat stressed (10-h FHS). Each treatment was replicated five times, with 20 birds in each replicate group. As expected, the birds in NF-CT group showed significantly better performances for all the growth parameters, although birds who fasted for 8-h under heat stress exerted better growth and FCR in comparison to the other HS groups. Fasting of birds under heat stress significantly showed the lowest mortality. Like the NF-CT group, birds in 8-h FHS achieved significantly higher dressing percentage, breast meat, liver yields, and the lowest abdominal fat. Fasting for 8- and 10-h significantly increased breast meat pH and water holding capacity and thus reduced cooking loss. Fasting also improved the breast meat color quality by increasing redness (a*) and reducing the hue angle values comparable with the NF-CT group. A significantly upward trend in villi height (VH), width (VW) and crypt depth (CD) of gut segments was also observed in the birds of the 8-h FHS group. Total bacterial and coliform counts in cecum contents were reduced significantly with the increase in the fasting period. Benefit-cost analysis showed better profitability in the 8-h FHS group than other HS groups. Taken altogether, it can be concluded that broiler chicken exposed to 8-h fasting period is an effective approach to mitigate heat stress under hot and humid climatic conditions.
