Simple Summary: Different components of the coconut are being looked into and used as a potential substitute to create or substitute animal feed components. Different coconut products and by-products—such as coconut water, milk, copra, testa, flour, raw kernels, oil, and desiccated coconut—are used with livestock, especially ruminants and aquaculture industries. However, the use of coconut in animal feed may be limited by several things that make it less nutritious. There is a possibility to research new technologies, such as pre-treating coconut to reduce the effects of anti-nutritional substances before they can be used to feed the animals. This review article describes a few important discoveries, which gives a somewhat hopeful view of the future. Different parts of the coconut can and should be used more in animal feed. Coconut in animal feed makes it much cheaper to feed animals and helps them in the digestion process, growth, and health. However, innovative methods of processing, extracting, and treating coconut need to be encouraged to improve nutritional quality and make coconut products function efficiently in feed. The price of traditional sources of nutrients used in animal feed rations is increasing steeply in developed countries due to their scarcity, high demand from humans for the same food items, and expensive costs of raw materials. Thus, one of the alternative sources is coconut parts or coconut as a whole fruit. Coconut is known as the 'tree of abundance', 'tree of heaven', and 'tree of life' owing to its numerous uses, becoming a very important tree in tropical areas for its provision of food, employment, and business opportunities to millions of people. Coconut contains a rich profile of macro and micronutrients that vary depending on the parts and how they are used. It is frequently chosen as an alternative source of protein and fiber. Its uses as an antibacterial agent, immunomodulant, and antioxidant further increase its importance. Using coconut oil in ruminant feed helps to minimize methane gas emissions by 18–30%, and to reduce dry matter intake up to 4.2 kg/d. The aquaculture sectors also use coconut palm as an alternative source because it significantly improves the digestion, growth, lipid metabolism, health, and antioxidative responses. However, coconut is not widely used in poultry diets although it has adequate amount of protein and carbohydrate due to anti-nutritional factors such cellulose (13%), galactomannan (61%), and mannan (26%). This review considered the importance and potential of coconut usage as an alternative ingredient in feed and supplements in various livestock sectors as it has plentiful nutrients and functional qualities, simultaneously leading to reduced feed cost and enhanced production.

Royal jelly (RJ) was applied as a supplement in feed to examine its impact on rabbit buck fertility. The aims were to evaluate the effect of RJ on sperm progressive motility and on histology of testis in rabbits. Twenty male rabbits were divided into four groups, each consisting of five bucks: Control (0mg), T1 {100mg RJ/kg body weight (BW)}, T2 (200mg RJ/kg BW), and T3 (300mg RJ/kg BW), with dietary treatment administered for 8 weeks. Sperm progressive motility (%), testis weight (g) and diameter of seminiferous tubule (µm) were measured. T1 group showed significantly higher (P<0.05) sperm progressive motility and seminiferous tubule diameter compared to the other groups, while an excessive concentration of RJ had a negative impact on the sperm quality, potentially because its components may result in an imbalance in redox reactions due to antioxidative activity. It is concluded that an appropriate dose of RJ improved the reproductive characteristics, but the results do depend on the dose administered to the rabbit. [ABSTRACT FROM AUTHOR]
