“…The non-significant effect of the breed observed in the current study on the WBC count, Hb concentration, albumin, cholesterol and triglycerides, as well as the significant effect of the breed on the percentage of lymphocytes, total proteins and creatinine were consistent with what was stated in a previous study by Abdel-Hamid and El-Tarbany [43]. However, the later authors reported controversy results concerning plasma creatinine level as they found Rex to have higher significant level than NZW (0.66 vs. 0.65 mg/dL; P =0.001), but they confirmed the present results with the respect to total proteins, they found Rex to have higher significant values than NZW (5.74 vs.5.52 g/dlL P= 0.014).…”

“…Undoubtedly, the growth performance of NZW and Rex in the current study presented a marked deterioration and was certainly lower than those were recorded in earlier findings [42,43], which could be attributed to exposure to relatively higher ambient temperature [9,44]. On the other hand, the current averages of Al-Gabali rabbits were nearer to those documented previously [2,45].…”

“…The present results were in agreement with those reported by Khalil and El-Zarie [46]; they found that Saudi Gabali (S) had lower average at all ages studied than Spanish maternal line called Vline (V). The growth performance of NZW was similar to that of Rex except for ADFI (P <0.001), the NZW was significantly higher than Rex [43].…”

“…They also found higher levels of liver enzymes (AST and ALT) in native breeds compared with imported ones, which disagreed with the present results, but their experiment was carried out from September to April (comfortable temperature). Abdel-Hamid and El-Tarbany [43] recorded statistically significant differences with respect to the breed for AST, ALT, urea, Hb concentrations, and PCV%, but these differences were in interaction with dietary supplement of the bee pollen. With regard to the current results of liver (ALT and AST) and kidney (urea and creatinine) function tests, it is clear that there is a significant improvement in these functions in Al-Gabali compared to other breeds, which reflects the health status, and consequently less exposure to heat stress and this conclusion is reinforced by Marai and coauthors [11] who observed an increase in liver and kidney function tests in male rabbits under Egyptian semitropical climatic conditions.…”

This study was constructed to investigate the differences between three breeds of rabbits [New Zealand White (NZW), Rex and Egyptian Gabali (Al-Gabali)] under heat stress regarding growth traits, hematological, biochemical and immunological parameters, oxidative stress biomarkers as well as metabolic hormones. Thirty rabbits of each breed (4 weeks of age) were subjected to heat stress (32 ± 1°C, 70-80% relative humidity) in the summer season at the period from mid-July to the end of August 2019. Blood samples were collected at 10 th week of age. The results revealed that body weights of NZW and Rex were higher by 205 and 145 g, respectively than those of Al-Gabali as well as average daily gains of NZW and Rex were higher by 4.42 and 3.40 g/day, respectively compared with Al-Gabali (P <0.05). Average daily feed intake of Rex was lower by 7.65 g/day than those of NZW and 2.89 g/day compared with Al-Gabali (P <0.05) and they had the lowest feed to gain ratios (3.58±0.097). Aspartate aminotransferase, urea and creatinine were significantly lowered in the plasma of Al-Gabali compared with NZW and Rex whereas, Al-Gabali recorded higher total proteins (5.90±0.048 g/dL), total globulins (2.50±0.054 g/dL), antibody titer against sheep red blood cells (6.38±0.111) and superoxide dismutase (7.42±0.163 IU/L) than NZW (5.66±0.069 g/dL, 2.21±0.084 g/dL, 4.90±0.068 and 6.80±0.053 IU/L, respectively) and Rex (5.74±0.072 g/dL 2.25±0.095 g/dL, 4.25±0.095 and 6.88±0.050 IU/L, respectively). Al-Gabali bunnies had higher immunoglobulin G, immunoglobulin A, catalase and glutathione peroxidase than NZW and Rex. However, Al-Gabali recorded the lowest insulin (15.64±0.20 ng/mL), growth hormone (45.80±0.48 ng/mL) and triiodothyronine (136.20±2.15 ng/mL). In conclusion, Al-Gabali rabbits were better adapted to heat stress compared with NZW and Rex, which was reflected in the improvement of health, immunity and oxidative stress indicators as well as lower plasma metabolic hormones, but they didn't have the genetic potential for growth traits.

“…The dosage of 1 g/kg was reported to improve the fatty acid profile (in particular in the case of poly unsaturated fatty acids) in the Japanese quail [119]. Similar results were reported upon addition of the bee-collected pollen to rabbits' diet: the average daily intake, net profit, and the final body weight of rabbits supplemented with 350 mg/kg of the bee-collected pollen were higher compared to the control group [120]. The blood parameters, such as haemoglobin, urea, and packed cell volume, differed significantly.…”

Pollen is recognized as an excellent dietary supplement for human nutrition, which is why it can be found in different forms on the market (granules, capsules, tablets, pellets, and powders). But, the digestibility of pollen's nutrients is strongly affected by the presence of a pollen shell, which can decrease the bioavailability of nutrients by 50% and more. Since consumers have become more aware of the benefits of a healthy diet and the necessity to improve pollen digestibility, different pollen-based functional food products have been developed and extensive studies were done to estimate the beneficial effects of pollen-based feed on animal growth, health, and rigor mortise stage. Considering the positive effects of pollen nutrients and phytometabolites on human and animal health, the aim of this paper was to give an overview of recent achievements in the application of pollen in the formulation of functional food and animal diets. Special attention was paid to the effects of pollen's addition on the nutritional, functional, techno-functional, and sensory properties of the new formulated food products. Anti-nutritional properties of pollen were also discussed. This review points out the benefits of pollen addition to food and feed and the possible directions in the further development of functional food and feed for the wellbeing of everyone.Biomolecules 2020, 10, 84 2 of 36 improvement and for the prevention of some respiratory infections. In addition, they emphasized the fact of the longevity of some residents of Ukraine and Russia which can be linked to their regular consumption of honey enriched with pollen [2]. Since then, a significant "breakthrough" about the application of pollen as a dietary supplement has been made and the number of available research articles has drastically increased.Nowadays, pollen is often recognized as the "only perfectly complete food" [4], and "the world's best food product" [5]. The dominant presence and high content of carbohydrates, proteins, and lipids highlights pollen as an ideal natural supplement that provides energy; it has good nutritional value, regulates certain biochemical functions, and strengthens the body's immune and physiological systems [4,6]. Furthermore, pollen is a rich source of different important compounds (Figure 1)-vitamins (with the prevalence of group-B vitamins) [7,8], carotenoids (such as lutein, β-cryptoxanthin, and β-caroten) [9], minerals [10][11][12], and polyphenols [13][14][15], which makes it attractive for use in the diets of children and adults suffering from certain avitaminoses and loss of appetite.
