Targeted CSN2 codon-67 genotyping supports A2-oriented breeding and herd management. We compared Kompetitive Allele-Specific PCR (KASP) with a locally implemented gel-based tetra-primer amplification refractory mutation system PCR (T-ARMS PCR) workfl...
The application of natural colorants in cheese manufacture is gaining increasing interest as an alternative to synthetic additives. This study investigated the incorporation, stability, and technological effects of blackcurrant (Ribes nigrum L.) anth...
European Protected Designation of Origin (PDO) and Protected Geographical Indication (PGI) cheeses represent a diverse sector in which geographical origin, production rules, species, territorial context, and market orientation shape product value. Th...
Heat stress is frequently associated with reduced dry matter intake (DMI), milk yield, and physiological alterations in Holstein dairy cows. The aim was to evaluate how prior exposure to heat stress affects feed intake, milk production, energy balanc...
Milk sample collection before attaching the milking cluster for bacteriological and cytological examination is a standard clinical diagnostic procedure in dairy production. Collecting samples premilking can be difficult under certain field conditions...
Tail inflammation and necrosis in dairy cows are increasingly reported, yet the early stages of their development and dynamics remain unclear. We conducted a longitudinal study to characterize the macroscopic pathogenesis of tail lesions throughout t...
Lameness is a major welfare and economic disorder in dairy production and a clinical sign with multiple causes. This review focuses on claw horn disruption lesions (CHDL), a major cause of periparturient lameness. Although hoof-centered prevention an...
The chemical composition of donkey and sheep milk showed significant differences, with donkey milk containing less fat and protein and a higher level of lactose, while sheep milk had more dry matter and a higher proportion of casein and saturated, un...
Injectable trace mineral supplementation (ITMS) has been proposed to support physiological adaptation during critical stages in dairy cattle; however, field-based evidence from pasture-based seasonal-calving systems remains limited. This study evalua...
Our first objective was to quantify the associations between health-related events (HRE) before insemination, the relative increase in estrus intensity (REI) at insemination, and the probability of cow-level pregnancy per artificial insemination (P/A...
Dairy cattle are particularly susceptible to welfare challenges that can negatively impact their behaviour, physiological responses, milk yield, and overall health. These challenges include rough handling by unfamiliar people, extreme climatic condit...
Teat-end hyperkeratosis (THK) is a welfare concern in dairy cows, associated with pain, discomfort, and increased mastitis risk. Identifying risk factors associated with THK may support targeted preventive management. This cross-sectional observation...
Effective colostrum management is essential to ensure adequate transfer of passive immunity (TPI) and reduce neonatal morbidity in calves. This study evaluated the impact of pasteurization on colostrum microbiological and immunological quality and it...
Chemical contamination of milk represents a relevant food safety concern, particularly in countries where systematic monitoring programs are still limited. In Algeria, information on human exposure to aflatoxin M1 (AFM1) and per- and polyfluoroalkyl...
Postpartum dairy cows fed more rapidly fermentable starch sources have depressed dry matter intake (DMI), compounding the risk of negative energy balance and hepatic lipid accumulation. Rumen-protected choline (RPC) is supplemented to periparturient...
Heat stress (HS) is a major issue affecting productivity and physiological responses in dairy cattle. Advances in gene function research have made it possible to identify favorable genotypes for HS tolerance. This study evaluates the combined effects...
This study investigated the impact of moderate teat-end hyperkeratosis on milk somatic cell count (SCC) and bacterial count (BC) in Holstein cows. Comparing teat-end scores (TS) 2 and 3, we found that TS3 quarters exhibited significantly higher SCC (...
The dairy industry is increasingly seeking natural alternatives to synthetic additives to meet the growing demand for clean-label and functional foods. Bee-derived products (BDPs), including propolis, honey, bee pollen, bee bread, and royal jelly, re...
Breed and herd are major determinants of milk productivity and efficiency. This study evaluated 1508 lactating cows from three dairy (Holstein, Brown Swiss, Jersey) and three dual-purpose (Simmental, Rendena, Alpine Grey) breeds across 41 multi-breed...
Mycotoxins are toxic fungal secondary metabolites that can contaminate the feed of dairy animals and can be transferred into milk and dairy products. This study aims to assess the occurrence of major mycotoxins in 190 samples of milk-based infant foo...
This study evaluated the effects of replacing alfalfa hay with sulla [Sulla coronaria (L.) B.H. Choi & H. Ohashi] hay or sulla haylage in pasture-based diets for lactating Sarda ewes on milk production, milk composition, and nutrient utilization...
