Additionally, integrating local feedstuffs and non-human-edible products can further reduce the carbon footprint and feed expenses. 4.2 Software tools and models for optimal feed formulation The use of advanced software tools and models is essential for optimizing feed formulation. These tools can handle complex variables such as fluctuating feed prices, nutrient compositions, and animal requirements. For example, evolutionary multi-objective optimization algorithms like NSGA-II can minimize feed costs while meeting nutritional requirements, providing a set of optimal solutions for decision-makers (Uyeh et al., 2019). Similarly, precision nutrition models, such as the Agricultural Modeling and Training Systems (AMTS) CattlePro, can simulate the effects of different diet formulation frequencies on dairy cattle performance, demonstrating significant economic benefits from more frequent diet adjustments (White and Capper, 2014). These tools facilitate efficient decision-making and can significantly enhance the economic viability of feed formulation strategies. 4.3 Role of precision nutrition in reducing feed wastage Precision nutrition plays a pivotal role in reducing feed wastage and improving overall feed efficiency. By customizing diets to the specific needs of individual animals, precision feeding ensures that nutrients are utilized more effectively, thereby minimizing waste (Gaillard et al., 2020). For instance, precision feeding can reduce lysine intake and nitrogen excretion in pigs without compromising their performance, leading to lower feeding costs and environmental impact (Andretta et al., 2016). Additionally, precision supplementation in heifer development programs can optimize individual animal intake, reduce feed overconsumption, and improve uniformity in growth and reproductive performance (Dagel et al., 2022). These strategies not only enhance feed efficiency but also contribute to the sustainability of livestock production systems. 5 Impact of Feed Quality on Goat Productivity 5.1 Influence of feed quality on milk yield and meat production Feed quality significantly influences both milk yield and meat production in goats. High-quality feed formulations, such as those incorporating Moringa oleifera silage and Chlorella vulgaris microalgae, have been shown to improve milk production and composition. Specifically, replacing up to 40% of the concentrate mixture with these components increased daily milk production, milk fat, and lactose concentrations, as well as feed efficiency in Damascus goats (Table 1) (Kholif et al., 2022). Similarly, the inclusion of mango seeds as an alternative energy source in the diet of dairy goats resulted in higher milk yield and improved milk composition, including increased total solids, protein, and fat content (El-Sanafawy et al., 2023). For meat production, the use of Ginkgo biloba residues to partially replace alfalfa hay pellets in the diet of finishing goats improved growth performance and meat quality, demonstrating the potential of high-quality feed to enhance both milk and meat productivity. 5.2 Improving digestibility and feed conversion efficiency Improving the digestibility and feed conversion efficiency of goat diets is crucial for optimizing production. Studies have shown that the inclusion of yeast-fermented palm kernel cake protein in place of soybean meal can enhance the digestibility of dry matter, crude protein, and fiber, thereby improving overall feed utilization efficiency (Chanjula et al., 2022). Additionally, the use of agro-industrial by-products like yeast- or EM-fermented cassava peel has been found to maintain feed intake and digestibility while significantly reducing feed costs, thus enhancing feed conversion efficiency (Gunun et al., 2023). Furthermore, the supplementation of diets with bee bread extract has been shown to improve the digestibility coefficients and nutritive value, leading to better feed conversion and daily weight gain in suckling kids (Farag et al., 2021). 5.3 Addressing feed safety concerns (contaminants, mycotoxins) Ensuring feed safety is paramount to maintaining goat health and productivity. Contaminants and mycotoxins in feed can have detrimental effects on animal health and performance. The use of slow-release urea as a partial replacement for soybean meal has been shown to improve feed efficiency and reduce the environmental footprint without compromising animal health, indicating a safer alternative to traditional protein sources (Grossi et al.,
