Modern dairy farming faces the dual challenge of meeting global food demands while mitigating its environmental impact, particularly greenhouse gas (GHG) emissions, such as methane (CH4), a potent contributor to climate change. This review explores the role of Precision Livestock Farming (PLF) technologies in monitoring and reducing CH4 emissions from dairy cattle. We evaluate state-of-the-art methods, including direct monitoring (e.g. respiratory chambers, GreenFeed systems) and indirect approaches (e.g. infrared milk spectroscopy, AI-driven analytics), alongside mitigation strategies such as nutritional optimisation, genetic...

This study aimed to estimate heritabilities of piglet birth-weight traits and to investigate the relationships between piglet birth-weight and litter-size traits using field data from Czech Large White and Landrace sows. Data including 86 241 piglets from 5 536 litters were analysed using repeatability, genetic, and genomic models. The investigated piglet-weight traits included arithmetic mean birth weight (MBW), within-litter standard deviation (SDBW), coefficient of variation in birth weight (CVBW), and the proportion of small piglets in the litter (SMALL). Heritability rates of piglet-weight traits were low, with the highest estimates for...

This study aimed to evaluate the effects of dietary administration of peppermint (Mentha piperita) alone and in combination with southernwood (Artemisia abrotanum) on performance, body and carcass composition, physicochemical characteristics, and amino acid composition of breast meat in broilers under Eimeria challenge. A total of 160 14-day-old male broilers (Ross 308) were randomly assigned to four dietary groups: the control (C) group was fed a basal diet; the CC group received a grower diet containing the coccidiostat robenidine; the M group was fed the diets with the addition of 20 g peppermint/kg of diet; the MS group...

This study was conducted to examine the effects of Moringa oleifera (MO) seed powder on the performance and gut health of broilers challenged with E. coli. A total of 720 one-day-old Ross 308 broiler chicks were randomly allocated to 72 pens across two separate rooms, following a 2 × 6 factorial design. The factors per room included (i) challenge: no or yes, and (ii) feed additive: control (none), antibiotic [oxytetracycline (OTC) at 0.5 g/kg], MO 0.1%, MO 0.2%, MO 0.4%, and MO 0.8%. At 9 days old, birds in both challenged and non-challenged rooms were inoculated with 1.5 ml of E. coli-O157:H7...
