Abstract
AbdallahMasoud El SayedMasoud: Evaluation of chenopodium quinoa willd as a new fodder crop underEgyptian condition. Unpublished M.Sc. Thesis, Department of Animal production, Faculty of Agriculture,Ain Shams University, 2016.
This study aimed to evaluate the productivity, chemical composition ofchenopodium quinoa willd as well as In vitro and In vivo evaluation of inclusion quinoa hay in lambs ration. Two seedtypes of Chenopodium quinoaWilld .cv. Hualhuas and CICA were cultivated at two different locations (non saline soil and saline soil).At harvest stage, plant from one square meter in the central of each plot were cut at ground level and productivity was determined. Invitro evaluation of quinoa hay was applied on two steps the first was to evaluate the feeding value of Chenopodium quinoa willd plant as a single source of feed in comparison with clover hay, where the two stage in vitro technique was applied and the second was to evaluate effect of substituting clover hay with quinoa hay in ruminant rations, where the one stage In vitro technique developed was applied. The best substituting level of quinoa cultivated under saline soil condition was applied in the growth trial. Which twelve growing Barqi male lambs with mean initial live body weight of 24.58 ±1.34 kg were divided into two similar groups, six animals each. The animals were randomly assigned to receive one of the two rations for 90 day. Feed intake, nutrient digestibility, rumen fermentation parameters, blood parameters, body weight gain and feed conversion were evaluated.
In general, CICA cultivar significantly produced higher forage yield than that obtained from Hualhuas .The maximum forage yield of CICA cultivar recorded under non-saline at summer season.The cultivated quinoa varieties recorded lower OM content and higher Ash, Protein, Ether Extract, natural detergent fiber (NDF) and acid detergent fiber (ADF) contents but lower OM content compared to clover hay. No significant (P>0.05) differences were recorded for In Vitro DM and OM disappearance (IVDMD and IVOMD) for quinoa plants (CICA cultivar) cultivated under salinity condition compared to clover hay.The feed intake as dry matter intake (DMI) and total digestible nutrient intake (TDNI)eitheras g h-1 d-1 or g kg0.75 d-1 was recorded numerically higher value for quinoa group compared tocontrol group.The differences were not significant (P>0.05) for both DMI and TDNI as g kg0.75 d-1. The animals fed ration containing quinoa hay recorded lower average total bacterial count, total Entodenium and total protozoa count in comparison with the animals fed alfalfa hay as single source of roughage and higher values of ammonia concentration compared to quinoa group at 0, 3 and 6 hrs post feeding as well as the mean values. No significant differences were recorded between the control and quinoa groups in all nutrients digestibility as well as the nutritive values as TDN and DCP. The quinoa group recorded significantly higher serum total protein content compared to control group. While no significant differences were recorded in Albumin Globulin, Cholesterol, ALT, AST, Alkaline phosphates, Urea and Creatinine.Insignificant differences were recorded between the control and quinoa group in final body weight, total gain and average body weight gain. Also non significant differencesin the feed conversion as DM, CP and TDN for the control group were observed compared to quinoa group.
It could be used quinoa as a feed for sheepreplaced by 50% forage portion in sheep rations.
