Abstract

The present study is a meta-analysis of the literature on nutritional biochemical efficiency in ruminants, based on publications between 2020 and 2024. The main objective was to evaluate how the digestion and absorption of nutrients, such as proteins, fibers and carbohydrates, impact the health and productivity of ruminants, including cattle, sheep and goats. Twenty-five studies were selected that met the inclusion criteria, such as the use of quantitative data and the availability of nutritional indicators, such as digestibility and volatile fatty acid (VFA) production. Dietary interventions, such as the addition of prebiotics and digestive enzymes, were analyzed to determine their effect on nutritional efficiency. Prebiotics, such as inulin and fructooligosaccharides (FOS), improved fiber digestibility by 12%, while enzymes showed a more variable improvement of 8% in carbohydrate digestibility. The study used statistical tools to assess heterogeneity between studies and robustness of results. Considerable variability in ruminant response to digestive enzymes was identified, and subgroup analysis indicated that species influences the effects of dietary interventions. Although publication bias was not significant, it is recommended that future research publish both positive and negative results to improve overall understanding of interventions. It is concluded that personalized diets, based on species-specific needs, can optimize nutritional efficiency in ruminants.

Abstract

This study conducted a meta-analysis to assess the importance of soil management in improving livestock production. Twenty-five empirical studies published between 2020 and 2025 that met specific inclusion and exclusion criteria were selected, focusing on soil management practices such as crop rotation, direct seeding, and cover crops. The search was conducted in academic databases such as Scopus, Web of Science, and Google Scholar, using relevant terms to ensure the quality and timeliness of the data. The results indicated that all soil management practices evaluated have significant positive effects on forage production and livestock health. Crop rotation showed a 15% increase in forage production, while direct seeding and cover crops increased production by 12% and 10%, respectively. The calculated effect sizes were 0.75, 0.68, and 0.62 for crop rotation, direct seeding, and cover crops, respectively, with moderate variability between studies. Subgroup analysis revealed that the practices were most effective in arid and semiarid regions and in dairy cattle systems. Although slight asymmetry in publication bias was identified, it was not found to significantly affect the results of the meta-analysis. Limitations of the study include variability in methodologies and quality of the studies. In conclusion, adopting sustainable soil management practices can significantly improve livestock production, highlighting the need to consider regional and livestock type-specific factors.

Abstract

This study reports on an intervention conducted in a Cuban dairy farm with structural and technological conditions representative of national production systems, aiming to identify and address key constraints limiting sustainable productivity. The initial diagnosis revealed deficiencies in replacement heifer quality, degraded grazing pastures, and low reproductive efficiency. In response, a four-year strategic transformation plan was implemented, focusing on enhancing productive efficiency and business profitability. The herd comprised predominantly crossbred Holstein cows, with some purebred Holsteins selected for their high milk yield potential. Results demonstrated a marked improvement in performance, with milk yield per hectare increasing from 2,720 to 5,353 liters and reproductive success rising from 70% to 85%. These gains were accompanied by a significant reduction in production costs, achieved through optimized pasture use and reduced dependence on external feed supplements. The intervention transformed the farm into an efficient agribusiness model, characterized by rational input use, sustainable pasture intensification, and genetic and reproductive improvements. Overall, the case study underscores the feasibility of achieving high milk yields under low-input tropical systems by integrating sustainability, productivity, and profitability, offering a replicable model for strengthening the dairy sector in similar environments.
