Automated activity monitoring (AAM) systems are critical in the dairy industry for detecting estrus and optimizing timing of artificial insemination (AI), thus enhancing pregnancy success rates cows. This study developed a predictive model to improve by integrating AAM data with cow-specific environmental factors. Utilizing from 1,054 cows, this compared outcomes between two AI timings—8 or 10 h post-AAM alarm. Variables such as age, parity, body condition, locomotion, vaginal discharge...

Integrated systems are efficient technologies used for diversifying production and promoting agricultural sustainability. The benefits of double intercropping well-established in research. With advancements sustainable food technology, some studies have explored triple by adding legumes. However, methods must be comprehensively understood. This study aimed to evaluate the dry mass, fermentation profile, nutritive values silage from maize based intercropping. experiment was conducted field,...

SUMMARY Sunflower as silage is an alternative to be used in the off-season, when water shortage makes traditional crops unfeasible. However, exclusive sunflower silages have levels above 70 g/kg DM ether extract, which may impair ruminal fermentation. Thus, ensiling with tropical forages can bring benefits quality of silage. This study evaluated fermentation profile and nutritional value cultivars Urochloa brizantha off-season. was a completely randomized experimental design four...
