High LDH in fattening calves (weaned), reasons?
4 answers
Elevated lactate dehydrogenase (LDH) levels in fattening calves post-weaning could be influenced by various factors. Research suggests that LDH activity in cattle can fluctuate during feeding trials, with peaks observed at different time points. Additionally, serum growth hormone (GH) concentrations were found to vary between different breeds and sexes of calves, potentially impacting metabolic processes that could affect LDH levels. Furthermore, weaning strategies can also play a role, as delayed weaning was associated with improved average daily weight gain compared to abrupt weaning, which could impact metabolic markers like LDH. Therefore, a combination of factors such as feeding regimes, breed differences, and weaning practices may contribute to higher LDH levels in fattening calves post-weaning.
Are separate biofertilizers necessary for intercropping?
5 answers
Separate biofertilizers can significantly enhance intercropping systems. Studies show that biofertilizers like mycorrhiza fungi and bacteria can improve nutrient content, essential oil quality, and yield in intercropping setups. Biofertilizers aid in nutrient transfer between plants, balancing belowground competition, and increasing overall productivity in intercropping systems. Additionally, the application of biofertilizers has been found to positively impact essential oil, fatty acid, and phenolic compound content in intercropped plants, leading to a more sustainable cultivation system compared to sole cropping under low-input conditions. Therefore, utilizing separate biofertilizers for intercropping can be crucial for maximizing yields, improving essential oil quality, and promoting sustainable agriculture practices.
