Effect of Using Onion Seed and Moringa Seed Oil on Productive and Physiological Performance of Growing Rabbits Under Hot Climate Conditions.

Abstract

A completely random experiment was conducted to evaluate onion and moringa seed oils or their mixture under climate summer conditions on growth performance, carcass traits, rectal temperature, respiration rate, blood biochemistry, digestibility coefficients, and economic efficiency of growing rabbits, from June, to August, 2015.A total of 108 Bauscat rabbits, weaned at 5 weeks of age with an average initial body weight of 528.80 ± 1.49,g were randomly distributed into four experimental treatments (27 rabbits/ each) and each treatment was sub-divided four 3 replicates of nine rabbits each. Rabbits were fed the basal diet either un supplemented or supplemented with 1g onion seed oil/Kg diet, or 1gmoringaseed oil/Kg diet and their combination 0.5 g onion seed oil + 0.5 g moringa oil/Kg diet throughout the whole experimental period which lasted for 3 months. The experimental basal diet was isonitrogenous (CP=17.0 %) and isocaloric (2536 Kcal/Kg DE).Results obtained showed thatthe percentages of total saturated fatty acids (TSFA) in moringa oil (23.88%) were higher than in onion oil (8.71%). Moringa oil contains a high level of monounsaturated fatty acids (MUSFAs) especially oleic acid (71.43%) than onion oil (8.71%). Total unsaturated fatty acids (TUSFAs), especially PUSFAs (linoleic) in onion oil were higher than that in moringa oil .Under the high ambient temperatures final body weight, daily gain and total gain of growing rabbits were significantly (P ≤ 0.05) increased and feed conversion values were improved with dietary supplementation with either moringa oil or onion oil and their mixture compared with those of the control group from 5-17 weeks of age. However, feed intake and viability rate were not significantly influenced by experimental dietary

Effects of Rocket Seed Oil, Wheat Germ Oil, and Their Mixture on Growth Performance, Feed Utilization, Digestibility, Redox Status, and Meat Fatty Acid Profile of Growing Rabbits

“…Oral administration of RSO, WGO, and their mixture improved the serum total protein as well as albumin and globulin levels compared to the control group. In agreement with the current results, the serum total protein as well as albumin and globulin levels improved significantly (p ≤ 0.05) when the rabbits were given the mixture of moringa oil and RSO, followed by individual moringa oil and RSO supplementation or growing rabbits that received moringa oil alone or with onion oil [70,71]. The significant increase in serum total protein and albumin observed in rabbits that were administered orally with RSO, WGO, and their mixture indicated the ability of these oils to stimulate the regeneration of hepatic tissue, which increased protein synthesis in the liver and improved the functional status of the liver cells [12,83] or these oils had a positive effect on thyroid hormone secretion, which could affect the metabolism of nutrients (Table 5).…”

“…In parallel to our results, using onion or moringa oils or a mixture of them significantly (p ≤ 0.05) improved digestibility coefficients of CP and EE compared to the control group. Meanwhile, the digestibility of DM, OM, CF, and NFE was not affected significantly by the addition of different oils [70,71]. In this line, the addition of 1 g RSO/kg diet or 1 g onion seed oil/kg diet and their combination in the growing rabbit's diet increased (p ≤ 0.05) the digestion coefficients of CP and EE compared to the control group [17].…”

Effect of Spraying Moringa Oil on Embryonic Development, Hatchability, Physiological Parameters, Post-Hatch Chick Growth and Bacterial Contamination of Fertile Quail Eggs

“…Spraying Japanese quail eggs with natural disinfectants or natural oils as natural disinfectants (pre-incubation) is a good way to improve the growth performance (feed intake, body weight and body weight gain) of chicks at 14 days of age and improved feed conversion as reported by Abdel-Hafez, 2017 andFouad et al, 2018). Sayed Ahmed et al, (2019) found that the dietary Moringa oil supplementation may help overcome the negative effects of heat stress on growth performance…”

“…There was a non-significant difference in counts of different white blood cells (%) in chicks (Table 8). Sayed Ahmed et al, (2019) noted that total blood protein and globulin were significantly increased (P≤0.05) due to dietary Moringa oil compared to the control group. However, the globulin level has been used as an indicator of increased immunity and a source of antibody production.…”
