Feed is the single largest expense in dairy farm production. Thus, it is important for producers to consider alternatives to traditional feedstuffs that could decrease the cost of feeding the animals while maintaining optimum animal performance. Grocery store waste (GSW) is one option to investigate as an alternative for the use of feeding dairy cattle. This includes fruits, vegetables, and bread/pastry products. Ruminants have the ability to derive nutrients from sources humans and other non-ruminants cannot. Therefore, ruminants can play an important role in recycling discarded materials from grocery stores. A literature review was conducted using online databases, such as Science Direct, Pubmed and Agricola. The objective of this review was to determine the nutritional, economical, and environmental benefits of using GSW to feed dairy cattle by evaluating different processing alternatives available to improve preservation and quality of this product. Grocery store waste takes up space in landfills and also contributes to the production of greenhouse gases. One reason so much grocery store waste is produced is because of the high standards of consumers. Consumers will often not buy produce that is blemished, bruised, oddly shaped, or discolored. These products are still nutritionally valuable, yet they are discarded, and cattle can maximize nutrient utilization if these are incorporated into a balanced ration. Viable preservation options include silage and dehydration. Based on these results, GSW can be fed to dairy cattle, potentially reducing costs, and environmental impact with no detrimental effects on production. Further investigation is required to determine nutritional characteristics and to improve preservation methods.
