- Rotavirus species A (RVA) significantly contributes to acute gastroenteritis in both humans and various animals, including rabbits, but detailed genetic studies on rabbit strains are limited.
- A new rotavirus strain (C-3/15) identified from a Mexican commercial rabbitry outbreak revealed a G3 P[8] genotype, which hasn't been previously reported in rabbits and shows close genetic ties to human rotaviruses.
- This finding suggests possible interspecies transmission of rotaviruses, marking the first molecular study of RVAs in rabbits in Mexico and highlighting the presence of human-associated genotypes in a rabbit with enteric disease.

The objective of this study was to analyze published results that support the hypothesis that the polyherbal product BioCholine Powder has rumen bypass choline metabolites through a meta-analysis and effect size analysis (ES). Using Scopus, Web of Science, ScienceDirect, PubMed, and university dissertation databases, a systematic search was conducted for experiments published in scientific documents that evaluated the effects of BioCholine supplementation on the variables of interest.

Article Synopsis
- This study assessed the impact of dietary essential oil supplementation (EOS) on the growth, blood antioxidant levels, immune responses, and gut structure of weaned piglets using a meta-analysis of 31 studies.
- Results showed that EOS significantly improved daily feed intake, weight gain, and final body weight while reducing the feed conversion ratio and diarrhea occurrence.
- EOS also enhanced antioxidant markers in the blood and improved the immune response, alongside increasing intestinal villus height, suggesting that essential oils have beneficial effects as a dietary additive in piglets.
Article Synopsis
- Previous research highlights that sufficient choline nutrition during late gestation enhances fetal development, but early gestation's role remains under-explored.
- The current study examines the effects of a herbal choline source, Biocholine, on the development of offspring from ewes supplemented during early gestation.
- Results showed no significant differences in birth and weaning weights, milk yield, or quality between supplemented and non-supplemented ewes, but those given Biocholine had increased newborn weight despite reduced placental membrane development.
Article Synopsis
- - The study aimed to assess how bee pollen (BP) and propolis (PRO) affect the performance, health, and meat quality of growing rabbits, using 160 hybrid rabbits divided into four treatment groups.
- - Rabbits receiving propolis supplementation (PRO50) showed significant improvements in daily weight gain and feed efficiency, while all treatments with propolis and the combination of bee pollen and propolis reduced Eimeria oocyst counts, indicating better health.
- - Overall, propolis at the specified dosage was found to enhance growth and prevent coccidiosis in rabbits without compromising their health or the quality of their meat.
Article Synopsis
- * Three groups of tilapia were fed either a commercial diet only or the same diet supplemented with 250 mg or 500 mg of herbal vitamin C per kg.
- * Results showed that herbal vitamin C improved fish growth, reduced DNA damage, and significantly altered the water metabolite composition, with the 500 mg dose being the most effective.
Article Synopsis
- Electronic devices, specifically electronic noses (e-noses) like the Cyranose 320, are being tested for detecting volatile organic compounds (VOCs) in fresh Mexican cheese made from different dairy cattle breeds.
- The study utilized a combination of the e-nose and Solid-Phase Micro-extraction Gas Chromatography-Mass Spectrometry (SPME/GC-MS) to identify and analyze the VOCs present in the cheese samples.
- Results showed that the e-nose successfully distinguished between cheese made from Jersey and Holstein milk, with certain VOCs being more prominent in one breed, indicating its potential use in cheese authentication processes.
Article Synopsis
- - The study aimed to assess a polyherbal additive's (PA) effects on growth, energy use, and meat traits in finishing lambs, using 28 Pelibuey × Katahdin lambs assigned to four different treatment groups.
- - Results showed that lambs receiving low doses of PA (particularly the PA1 group) had improved growth rates, energy efficiency, and muscle characteristics compared to the control group, without significant impacts on overall intake or carcass yield.
- - PA3 treatment resulted in lower serum urea and higher serum albumin levels, indicating potential health benefits, but more research is suggested to fully understand PA's effects on lamb productivity and metabolism.
Choline chloride is used to provide choline in dog foods; however, in other domestic species, it has been replaced with a polyherbal containing phosphatidylcholine. A polyherbal containing , , , , and was evaluated in adult dogs through body weight changes, subcutaneous fat thickness, blood metabolites, and gene expression. Forty dogs (4.

- A study evaluated the effects of a polyherbal feed mixture on the growth and health of 40 Holstein calves, examining blood chemistry, biometry, and gene expression during their pre-ruminant to weaning period.
- The optimal treatment dosage of the polyherbal mixture was found to be 4 g/d, resulting in better weight gain, hip height, and thoracic girth compared to other doses.
- Gene analysis showed upregulation in processes related to immune response and metabolism, indicating beneficial effects on the calves' health and growth from the herbal treatment.
Digestion of cell wall fractions of forage in the rumen is incomplete due to the complex links which limit their degradation. It is therefore necessary to find options to optimize the use of forages in ruminant production systems. One alternative is to use exogenous enzymes.
