This study compared the effect of 2 pasture-based feeding systems, namely a traditional perennial ryegrass (PRG) diet, and a recently introduced, more sustainable multispecies swards (MSS) diet, on the functional lipid profile of raw milk. In addition to the 2 pasture diets, the study uniquely examined the combined effects of breed, namely Holstein Friesian (HF) or Jersey Holstein Friesian (JFX), and lactation stage in Ireland, spanning from March to November. Bulk milk samples (n = 144 yearly) for the 4 groups examined were collected for 4 wk per each of the 9 mo specified.

- The study aimed to assess how diversifying grass swards and reducing nitrogen fertilizer affect dairy cow performance over three years on different pasture types (monoculture, mixed with clover, and multispecies).
- Results showed no major differences in overall pasture production or sward nutritive value among the different types, but the multispecies sward led to higher milk and milk solids yield compared to the nitrogen-heavy monoculture.
- The breed of cows also played a role, with Jersey crossbreds producing less milk but with higher fat and protein content compared to pure Holsteins, resulting in more efficient milk solids production based on body weight.
Article Synopsis
- Low-voltage electrical safety training is crucial for workers, but traditional lecture-based methods are often ineffective.
- Virtual reality (VR) offers an immersive experience that enhances engagement and safety during training, making it a promising tool for industrial safety applications.
- A study involving 18 participants showed that VR training led to improved knowledge retention and positive feedback, suggesting it is a viable alternative to traditional methods.
In recent years, significant emphasis has been placed on the composition of pasture-based cow feed and the potential benefits of incorporating multispecies swards to improve sustainability and biodiversity. This study compared the effects of a conventional perennial ryegrass (PRG) monoculture supported by high-chemical N usage with a low-chemical-N application multispecies sward system (MSS) on the composition and quality of milk across lactation using spring-calving Holstein-Friesian (HF) and Jersey Holstein-Friesian (JFX) cows. Bulk milk samples (n = 144) were collected from each group at morning and evening milking on a weekly basis (n = 36) throughout lactation and analyzed for gross composition and physicochemical properties.

Trams often operate in shared or mixed-traffic environments, which raise safety concerns, particularly in hazardous situations. This paper adopts an international, mixed-methods approach, conducted through two interconnected studies in Melbourne (Australia) and Birmingham (UK).
