Responses of pubertal rabbits to dietary supplementation of ginger (Zingiber officinale rosc) rhizome powder

Abstract

Seventy two (72) sexed crossbred rabbits aged 6 months were used to determine the effect of ginger rhizome powder (GRP) supplementation on reproductive organ and serum sex hormonal characteristics of pubertal rabbits. The experimental rabbits were divided into 2 treatment groups comprising 36 males and 36 females. Each group was divided into 4 dietary treatments (BT1, BT2, BT3 and BT4 ) of 9 animals and replicated thrice with 3 animals per replicate in a completely randomized design (CRD). The animals were fed formulated diet containing 2900 Kcal ME kg-1 and 18% crude protein supplemented with GRP at the rate of 0, 5, 10 and 15 g kg-1 feed respectively. Rabbits in each dietary group were fed 50gms of Guinea grass leaf meal containing 27.6% CF (dry matter basis) occasionally as additional fibre sources. Feed and water were offered ad libitum and the study lasted for 10 weeks. Testosterone values of BT (5.83 ng mL-1) and BT (6.28 ng mL-1) and follicle stimulating hormone (FSH) levels of BT (1.15 mIU mL-1) were significantly influenced (p<0.05) by ginger rhizome powder. Bucks on BT3 and BT4 had lower luteinizing hormone (LH) level than the BT1 bucks. For the females, FSH and LH values ranged significantly (p<0.05) from 0.90 to 2.05 mIU mL-1 and 0.90 to 3.15 mIU mL-1 respectively. The 17â - estradiol and progesterone levels also ranged significantly (p<0.05) from 166.35 to 175.05 pg mL-1 and 15.45 to 16.80 ng mL-1 respectively. Ovarian weight of rabbit on BT was significantly (p<0.05) higher than those on BT1 but similar to those on BT2 and BT4 treatments. It was therefore concluded that the use of ginger rhizome powder in rabbit diets improved the weight of the ovary as well as enhances serum progesterone, estrogen and testosterone levels.

Proximate composition and mineral content of spices increasingly employed in the Mediterranean diet

“…The results of the present study were not in agreement with earlier studies (30,31) , which reported different mineral contents in ginger powder. In addition, the study of Prakash et al (15) showed that ginger powder contained 9⋅41 mg/100 g iron, 104⋅02 mg/100 g calcium and 204⋅02 mg/100 g phosphorous, of which calcium content was in accord to the present study.…”

Proximate, total phenolic, carotenoid, antioxidant activity, color, and FTIR analysis of red ginger powders (Zingiber officinale var. Rubrum) through the evaporation-crystallization process

“…The ready-to-drink red ginger product contributed 59.308-64.418; 12.741-24.112; 0.102-0.279; and 48.961-52.651% of the red ginger powder product for ash, fat, protein, and carbohydrate contents, respectively. These results also align with research conducted by [29], which showed that ginger powder is very rich in ash content and followed by water content. The ash content illustrates the amount of mineral elements contained in ginger so that high ash content can indicate the content that is good for health.…”

Process optimization for the development of fruit‐based diet drink: A low‐calorie approach

“…The tea extract influenced the sodium content of the diet drink significantly ( p ≤ .05), which is due to the sodium content of tea extract that is, 0.09% being determined to be the maximum quantity of sodium content in black tea. On the other hand, herb extract also contributed significantly ( p ≤ .05) to the sodium content of DDs which might be due to the presence of sodium in a ginger root, that is, 38.96 μg/g (Ogbuewu et al, 2014). Tea extract concentration affects potassium content of DDs inversely (Table 3) owing to its contribution in tea, that is, 30,362 μg/ 100 ml (Klepacka et al, 2021).…”
