the cost of feeding cattle [22] also looked at how different bagasse-
vinasse combinations with pineapple peel silage and sweet corn husk
and cob silage affected the daily body weight of animals. According to
the study, Animals fed the bagasse-vinasse mixture with pineapple
saw a weight gain that was much higher than those fed the other two
mixtures. The feed block is an alternative animal feed that must be
created. Forage, concentrate, and other nutrients are included in the
feed block in the proper amounts to suit the animal's nutritional
requirements [18], [34].

2.5 Feed conversion efficiency and waste disposal
Food wastes may be used as animal feed, solving issues with waste
management and food security while reducing the need for
conventional feed production, which is a resource and environment
intensive. When analyzing the use of food waste in animal feed,
factors such as the nutritional value of the wastes, the techniques used
to treat them, and the growth performance of the animals fed these
waste-based diets were all taken into account. Rajeh et al. [31]
identified optimal levels of food loss/food waste inclusion as well as
associated FCR values, as well as nutritional qualities such as dry
matter (DM), crude protein (CP), ether extract (EE), nitrogen-free
extract (NFE), and crude fiber (CF) (2020). Note that only studies
reporting the approximate compositions of the tested food waste
before creating experimental diets and before combining it with other
feed ingredients are included in this section (Table. 2).
It should be made clear that the research in this section only examines
the rough compositions of the food waste that was the subject of the
study before experimental diets were made and before it was
combined with other feed additives. Rajeh et al., [31], the nutritional
profile of food waste may also alter as a result of waste processing
techniques. For instance, fermentation at 60-80 °C for 4–10 led to
nutritional loss when compared to rotating disk drying food waste at
120 °C for 30 minutes. However, using either of the aforementioned
methods, the waste-based feed that was created had an adequate
