This investigation was carried out to evaluate the effect of incorporating 10% and 15% non-heat treated (NHT) and 10% and 15% heat treated (HT) Amaranth (Amaranthus hypochondriacus) seed powder into concentrate feed mixture consisting of rice (Oryza sativa) bran/polish and milling by products of black gram (Vigna mungo) fed to lactating goats (Capra hircus), on their body weight and blood serum parameters. A randomized complete block design with four replicates was used to compare five treatment groups. Control diet consisted of natural grass together with rice polish and milling by products of black gram, whereas Amaranth seed powder in different ratios as mentioned above was added to four experimental rations. All diets were formulated to meet NRC standards for dairy goats. Body weight was recorded and blood samples of the animals were drawn at the beginning of the experiment before commencement of the feeding trial and after every 30 days for a period of 03 months, during the feeding trial. The mean total cholesterol (TC) concentrations in the control, 10% NHT, 15% NHT, 10% HT and 15% HT experimental animals were 113.7, 112.03, 110.75, 101.99 and 120.01 mg/dL and the mean high density lipo-protein cholesterol (HDLC) concentrations were 75.48, 77.39, 72.56, 70.88 and 76.55 mg/dL respectively, at the end of the experiment. In contrast the mean low density cholesterol (LDLC) concentrations were 33.2, 28.6, 30.3, 27.8 and 38.3 mg/DL respectively, at the end of the experimental period. The mean triacylglycerol (TAG) concentrations ranged from 26.29-49.57(mg/dL), whereas mean weights of the lactating goats ranged from 39.35-47.42kg respectively, between different treatment groups. Total serum cholesterol, high density lipo-protein cholesterol and low density lipo-protein cholesterol content of all goats increased with the time irrespective of the diet. According to results, the tested feed rations have no significant effect (P>0.05), on the body weights of the animals and the tested blood serum parameters, compared to the control. Results from this study may hamper some of the initial enthusiasm with respect to potent cholesterol lowering properties of Amaranth products, in ruminant animals.
