Ruminants, Volume 5, Issue 2

Understanding the genetic and phenotypic basis of economically important traits is essential for designing effective breeding programs in livestock. This study aimed to evaluate the phenotypic performance and estimate genetic parameters for one repro...

The conservation of local breeds plays a strategic role in maintaining genetic variability, ensuring adaptive responses to environmental challenges, and preserving the cultural and socioeconomic structures of traditional communities. In this context,...

The rumen is the largest compartment of the ruminant stomach and plays a central role in the digestive physiology of bovine, ovine, and caprine species [...]

Cytokine and Anti-Müllerian Hormone (AMH) profiling were performed in prepubertal Murrah buffalo heifers’ post-progesterone supplementation and Co-synchronization (Co-synch) protocol. Cytokine (IFNγ, IL6, IL1, IL13, TNFα, and T...

The objective of this study was to evaluate whether the addition of fibrolytic enzymes to the diet of cattle in confinement improves feed digestibility weight gain; as well as evaluating the profile of fatty acids in the ruminal environment and in me...

This study evaluated the effects of organic trace mineral supplementation on growth performance, antioxidant indices, mineral status, and diarrhea incidence in dairy calves raised in arid climates. Twenty-five male Holstein calves were randomly assig...

Virtual fencing (VF) technology represents an innovative approach to livestock management, utilizing GPS-enabled collars to establish invisible boundaries through auditory and mild electrical stimuli. While VF offers potential benefits such as enhanc...

Leonardite (LEO), a microbial derived product rich in humic and fulvic acids, has been tested, due to its beneficial properties for health and well-being, as a feed additive, mainly in non-ruminant species. Although there are some reports of LEO supp...

In 2020, the European Union endorsed its “Farm-to-Fork” strategy, emphasizing the need for transparency in the food production chain and communication of the sustainability level and nutritional value of food products to the consumer thro...

Fetal programming suggests that maternal nutrition during gestation influences offspring growth, development, and productivity. This study evaluated the effects of prenatal protein-energy supplementation on the lifetime performance of Nellore cattle....

Enteric methane emissions from ruminants substantially contribute to global greenhouse gas emissions, necessitating effective mitigation strategies that also support animal productivity. This study assessed the efficacy of a multi-component feed addi...

Data for growth (birth, weaning and yearling weights) and carcass (longissimus muscle area, intramuscular fat percentage and depth of rib fat) traits and 50K SNP marker data to calculate the genomic relationship matrix were collected from 738 Brangus...

The aim of this study is to review the supplementation of polyphenol on milk composition and milk fatty acid content in dairy animal. A systematic review of literature was carried out by using Google Scholar, Scopus, and Science Direct databases. The...

The estimation of body chemical composition is necessary to determine the nutrient requirements of growing/finishing cattle, but recent analyses indicate that published equations provide erroneous results when applied to diverse breed types and sexes...

The phalanges of Karagouniko ewes and Hellenic goats were the subject of the present quantitative study, with the objective of determining whether any differences existed on the corresponding bones of the different digits. The lengths of the phalange...

Contamination by multi-mycotoxins in cattle feed can lead to increased susceptibility to diseases and loss of performance. The present study aimed to investigate the occurrence of multiple mycotoxins present in the diet of beef cattle feedlots in Bra...

The purpose of this study was to evaluate the effects of short- and long-distance road transport and temperament on β-endorphin (β-EP) concentrations in 23 Limousine bulls, aged 12 ± 2 months old, taking into account the related effe...
