■生姜(Zingiberofficinale)在反刍动物营养中作为生长促进剂和免疫刺激剂具有巨大的潜力。本研究评估了补充姜粉对Ossimi公羊瘤胃发酵的影响,生化参数,和抗氧化剂水平。
■15只Ossimi公羊,年龄10±1.3个月,体重30±1.5公斤。将公羊随机分为三个实验组:对照组(G1)接受标准饲料,而姜粉(G2和G3分别为5g和7g/kg体重[BW])在标准饲料之前混合在水中给予G2和G3组。
■对照组记录的干物质(DM)摄入量高于生姜处理组(p<0.05)。与对照组相比,生姜处理组在增重和饲料转化率方面显示出优越性(p<0.05)。DM的消化系数,粗蛋白,高剂量(7g/KgBW)的生姜补充显着增加了粗纤维(p<0.05),而有机物,乙醚提取物,无氮提取物的消化率保持不变。与对照组相比,给予5克生姜的公羊血清中的总蛋白和球蛋白明显减少(p<0.05),但是给予7克生姜的公羊有更多的这些蛋白质(p<0.05)。在生姜组中,血清肌酐水平明显低于对照组(p<0.01),尿酸,尿素,总脂质,甘油三酯,总胆固醇,葡萄糖,血清丙氨酸转氨酶,天冬氨酸转氨酶,碱性磷酸酶,和γ-谷氨酰转移酶。给生姜的公羊有明显的生长激素,胰岛素样生长因子-1,总超氧化物歧化酶,GSH-Px,TAC,免疫球蛋白(Ig)A,和IgG增强(p<0.01),与对照组相比,丙二醛浓度降低(p<0.01)。总短链挥发性脂肪酸显著增加,乙酸,丙酸,和异戊酸(p<0.05),NH3N和原生动物显著减少(p<0.01)。
■生姜粉(5g和7g)可以改善生长,免疫反应,抗氧化状态,和公羊的瘤胃参数。需要进一步的研究来评估生姜对不同类型动物的影响(牛,水牛,和山羊)开发新的饲料添加剂。
UNASSIGNED: Ginger (Zingiber officinale) has great potential as a growth promoter and immunostimulant in ruminant nutrition. This study assessed the impact of ginger powder supplementation on Ossimi rams\' rumen fermentation, biochemical parameters, and antioxidant levels.
UNASSIGNED: Fifteen Ossimi rams, aged 10 ± 1.3 months and weighing 30 ± 1.5 kg. Rams were randomly divided into three experimental groups: The control group (G1) received standard feed, while ginger powder (5 g and 7 g/kg body weight [BW] for G2 and G3, respectively) mixed in water was administered to groups G2 and G3 before their standard feed.
UNASSIGNED: The control group recorded higher dry matter (DM) intake values (p < 0.05) than the ginger-treated groups. The ginger-treated groups showed superiority (p < 0.05) in weight gain and feed conversion compared to the control group. The digestion coefficients of DM, crude protein, and crude fiber were significantly (p < 0.05) increased by a high dose (7 g/Kg BW) of ginger supplementation, whereas organic matter, ether extract, and nitrogen-free extract digestibility remained unchanged. Compared to the control group, the rams given 5 g of ginger had significantly less (p < 0.05) total protein and globulin in their serum, but the rams given 7 g of ginger had significantly more (p < 0.05) of these proteins. In the ginger groups, these levels were significantly (p < 0.01) lower than those in the control group for serum creatinine, uric acid, urea, total lipids, triglycerides, total cholesterol, glucose, serum alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, and gamma-glutamyl transferase. Rams given ginger had significant growth hormone, insulin-like growth factor-1, total superoxide dismutase, GSH-Px, TAC, immunoglobulin (Ig) A, and IgG enhancement (p < 0.01), and a decrease (p < 0.01) in malondialdehyde concentration compared to the control group. Significant increases in total short-chain volatile fatty acids, acetic, propionic, and isovaleric acids (p < 0.05), and significant decreases in NH3N and protozoa (p < 0.01).
UNASSIGNED: Ginger powder (5 g and 7 g) can improve growth, immune responses, antioxidant status, and ruminal parameters in rams. Further study is needed to evaluate the effect of ginger on different types of animals (cow, buffalo, and goat) to develop new feed additives.
