Lab-grown cells (also known as cell-based or cultured meat) are novel food innovations that face uncertain consumer acceptance. This review examines recent research (2020–2024) on consumer perceptions of lab-grown cells, focusing on three main areas: (1) public awareness and familiarity, (2) psychological and cultural aspects shaping perceptions, and (3) the impact of information on acceptance. Results show that the awareness of lab-grown cells varies widely across regions; in countries with high meat consumption, such as the USA and Australia, or where culinary delights are highly valued, such as France, respondents rated lab-grown cells...

This research explores the addition of mangrove (Sonneratia alba) fruit to reduce the production of methane and the total population of protozoa. The dosage for adding mangrove fruit is 0% (without addition), 1.5%, 3%, and 4.5% in sugarcane tops-based feed. Results include ruminal product fermentation, gas and methane emissions, total protozoa, microbial protein production, microbial biomass, and nutrient digestibility. The research findings showed that an additional 1.5% to 4.5% dose can reduce methane gas emissions and the total number of protozoa. The total number of protozoa at 4.5% (T3) reached 9.89 × 104 cells/ml and methane...

Monitoring the genetic diversity in livestock is a critical component for sustainable management of small and endangered breeds. In this paper we follow up the two most often used metrics of genetic diversity, the average inbreeding coefficients (F) and the effective population (Ne) size in 16 sheep breeds from four countries. The analysis was based on single nucleotide polymorphism (SNP) markers, with about 35 to 49 thousand SNPs and 19 to 98 individuals after quality control. The runs of homozygosity (ROH) method with the cgaTOH software was used to estimate FROH, for three different time points in the...

This study evaluated the potential of spent coffee grounds extract (CGE) as an antioxidant supplement in the diet of Nile tilapia (Oreochromis niloticus). Four experimental diets with varying CGE levels were formulated: 0% (CGE0, control), 2% (CGE2), 4% (CGE4), and 6% (CGE6). Nile tilapia (initial mean body weight = 38.65 ± 0.85 g) were cultured in fiberglass tanks at a stocking density of 20 fish/m2 under continuous aeration. The fish were fed three times daily at 5% of their total body weight. After an 8-week experimental period, the fish fed CGE-supplemented diets exhibited significantly higher growth rate compared to the...
