“…Also, volatile fatty acids play a direct role in bacterial cell integrity (Maertens et al, 2006). The present results are in correspondence with those obtained by Easa et al, (2018) who documented that supplemented 200 mg copper sulfate/kg in rabbits' diets significantly improved nutrient digestibility of DM%, OM%, and CP%. Also, Abd El-Moneim et al, (2013) found that the digestibility of CP was insignificantly improved by supplemented 40 or 80 mg Cu per liter in drinking water.…”

“…Another research study on other forms of Cu such as nano-copper by Refaie et al, (2015) revealed that supplementing weaning rabbit diets with nanocopper at dose 50 or 70 mg /kg diet led to an increase in FBW and PI compared to control. Also, Easa et al, (2018) recorded that NZW rabbits utilized a diet with CuSO 4 or Cu-nano showed significant greater growth performance compared to control rabbits. Finally, Charmaine and Hans (2021) documented that Cu can be included in growth promoting for weaning and growing pigs by reducing post weaning diarrhea and enhancing growth performance because Cu plays an important role in the digestive tract and bacterial count and changes the 3dimensional structure of bacterial proteins, which prohibits bacteria from exerting their pathogenic action and might disrupt enzyme structures and functions of bacteria by binding to sulfur or carboxylate-containing groups and amino acid groups of proteins.…”

This study was conducted to assess the influence of pumpkin seed oil (PSO), copper sulfate (CuSO 4 ) and their synergistic effects on the productive performance, physiological response and economic efficiency of weaning rabbits. Sixty weaned Californian male rabbits at 5 weeks of age with an average initial weight of 582.83 ± 34.47 g were randomly distributed into four experimental groups (15 each). The first group was fed the basal diet and served as a control (G1). While, the 2 nd (G2), fed the basal diet supplemented with 5 ml of PSO/kg diet; the 3 rd (G3), fed the basal diet supplemented with 200 mg CuSO 4 /kg diet and the 4 th (G4), fed the basal diet supplemented with 5 ml PSO and 200 mg CuSO 4 /kg diet. Results showed that rabbits in G3 and G4 had significantly higher final body weight (FBW), total body gain (TBG) and performance index (PI), while having lower feed consumption (FC) and feed conversion ratio (FCR) compared with 174 EL SPEIY e t al G1. Plasma IgG and IgM concentrations, total antioxidant capacity (TAC), and superoxide dismutase (SOD) significantly increased while, malondialdehyde (MDA) was decreased in all supplemented groups compared with G1. Economic efficiency was significantly improved in G3, followed by G4, while the worth value of economic efficiency found in G2 which significantly decreased compared with the control group. Conclusion:Pumpkin oil showed an improvement in productive performance and various blood characteristics, as well as copper, but copper had a great advantage in improving economic efficiency, especially when added alone, unlike pumpkin oil, which showed a decrease in economic efficiency compared to the control.

“…The elaborative review by Elghandour et al [5] advised the cautious incorporation of feed additives in equine nutrition. Few studies have been conducted on livestock species, including ruminants [6], poultry [7], swine [8], and rabbit [9]; however, the research conducted on the horses is scanty as per the literature collected. The results from any of the aforementioned species might not be approved in equines due to the variations in vulnerability levels, pharmacodynamics, and pharmacokinetics compared with other livestock species.…”

Applications, challenges, and strategies in the use of nanoparticles as feed additives in equine nutrition

et al. 2020

The rapid expansion of nanotechnology has been transforming the food industry by increasing market share and expenditure. Although nanotechnology offers promising benefits as feed additives, their usage in equines is primarily geared toward immunotherapy, hyper-immunization techniques, drug delivery systems, grooming activities, and therapeutic purposes. Nanoparticles could be engaged as alternatives for antibiotic feed additives to prevent foal diarrhea. Gold nanoparticles are proved to provide beneficial effects for racehorses by healing joint and tendon injuries. Because of the poor bioavailability of micro-sized mineral salts, the usage of nano-minerals is highly encourageable to improve the performance of racehorses. Nano-Vitamin E and enzyme CoQ10 for equines are no longer a simple research topic because of the increased commercial availability. Employing nanotechnology-based preservatives may offer a promising alternative to other conventional preservatives in preserving the quality of equine feed items, even during an extended storage period. While nanoparticles as feed additives may provide multitudinous benefits on equines, they could elicit allergic or toxic responses in case of improper synthesis aids or inappropriate dosages. The safety of nano-feed additives remains uninvestigated and necessitates the additional risk assessment, especially during their usage for a prolonged period. To adopt nano-feed additives in horses, there is an extreme paucity of information regarding the validity of various levels or forms of nanoparticles. Further, the currently available toxicological database on the topic of nano-feed additives is not at all related to equines and even inadequate for other livestock species. This review aims to provide new insights into possible future research pertaining to the usage of nano-feed additives in equines.
