Performance of Rabbits Fed Diets Containing Different Levels of Energy and Lesser Galangal (Alpinia Officinarum)

Abstract

This work aimed to study the effect of two different levels of ration energy supplemented with Alpinia officinarum. Rabbits were classified into six equal groups (G1-G6). The 1 st and 4 th groups received basal ration with 100 % and 90 % energy requirement and served as first and second control respectively. The 2 nd and the 3 rd groups received basal ration with 100 % energy requirement supplemented with Alpinia officinarum at the level of 0.5 and 1.0 %, respectively. The 5 th and 6 th groups received basal ration with 90 % energy requirement with Alpinia officinarum at the level of 0.5 and 1.0 %, respectively. The 90% energy containing diet showed significant increased (P<0.05) in DM and CF digestibility, while EE digestibility was significantly (P<0.05) decreased. Lesser galangal as feed additives showed significant (P<0.05) increased in DM, OM, CF, NFE digestibility and TDN value. There were significant interaction values between energy and supplementation levels on digestibility coefficient of DM, OM, CF, EE, NFE and TDN value. Supplementation of Lesser galangal at 0.5 % or 1% significantly increased final body weight gain, ADG, feed conversion, while slightly decreased feed intake. The 90% energy and 1% lesser galangal (G 6 ) recorded the best values of final body weight, body daily weight gain and feed conversion.The interaction values between energy and lesser galangal levels significantly increased (P<0.05) the carcass weight, dressing percentages and carcass cuts. The 90% energy and 1% lesser galangal (G 6 ) recorded the best values of carcass weight, dressing percentages and carcass cuts. Lesser galangal significantly (P<0.05) decreased the lungs (weight and % of SW); content of stomach and empty of small intestine (weight and % of SW). The interaction values between energy and lesser galangal levels significantly (P<0.05) increased the liver and total internal offal's (% of SW); lungs, full and content of stomach as well as digestive tract content (weight, g and % of SW). Dietary 90% energy requirements with 0.5 % or 1% lesser galangal showed the high values of net revenue, economical efficiency and relative economic efficiency, while recorded the low value of feed cost/ kg live body www.ccsenet.org/jas Journal of Agricultural Science Vol. 3, No. 4; December 2011 ISSN 1916-9752 E-ISSN 1916 242 weight (LE). Rabbits received the 90 % energy requirement with 0.5 % lesser galangal recorded the highest value of relative economic efficiency (111.4%) and the lowest value of feed cost/ kg live body weight (5.45 LE).

Effect of Dietary Inclusion of Galangal (Alpinia Galanga) on Growth Performance and Some Physiological Parameters of Broiler Chicks

“…Also, Srividya et al (2010) suggested that this positive effect on the performance traits of laying chickens due to galangal supplementation may be because it improves intestinal enzymes (glucase, oxidase, catalase, and peroxidase) that may be associated with better digestibility of different nutrients. Ibrahim et al (2011) reported that galangal has strong antioxidants and stimulates the body's immunity process; this may increase the growth performance and health status of laying hens that are reared under heat stress conditions. Blood constituents Data from Table (3) shows the chick's blood analysis, where it is noted that when compared to the control group, serum glucose levels were increased significantly (P=0.001) with galangal treatments, reaching 115.5, 117.4, 118.7, and 118.1 %, respectively.…”

“…The antioxidant action of galangal, according to Zhao et al (2010), is attributable to the presence of polyphenols, anthocyanin, glycosides, and thiocarbamates, which scavenge free radicals. Galangal also has a strong antioxidant capacity due to a combination of polyphenolic components (Ibrahim et al, 2011;Das & Santhy, 2015;Pahwa et al, 2016 andAbdel-Azeem andBasyony, 2019). The objective of this investigation was to study the impacts of galangal supplementary in broiler diet on productive performance, blood biochemical parameters, antioxidant status, carcass traits, economic efficiency and production index.…”
