Abstract
In the present experiment, there were two groups constituted of Pearl and Lavender varieties of guinea fowl. A total of 300 day-old keets 150 from Pearl and 150 from Lavender variety of guinea fowl were used. The aim of the experiment was to study comparative egg weight, fertility, hatchability, growth performance, carcass traits, hematological and biochemical parameters in Pearl and Lavender varieties of guinea fowl. For the study of growth performance, body weight and feed uptake were recorded at 2 weekly intervals throughout the experimental period. Growth parameters were studied in three different periods viz. Starter (1st-4th week), Grower (5th-8th week), Finisher (9th-12th week) and overall period (1st-12th) at two weekly intervals. At the end of 84th day, six birds from each group were randomly sacrificed for study of carcass yield, yield of cut up parts, organ weights and processing losses. At that time blood was also collected for haemato-biochemical parameters. The results of experiment indicated that the average egg weights were significantly (P<0.05) higher in Pearl as compared to Lavender variety of guinea fowl. The fertility and hatchability were higher in Pearl than Lavender variety of guinea fowl. Pearl had significantly (P<0.05) higher body weight gains than Lavender during all the periods. Pearl had significantly (P<0.05) lesser feed intake than Lavender variety of guinea fowl. Pearl had significantly (P<0.05) better Feed conversion ratio than Lavender during all the periods. The mean of dressing percentage with and without giblet were significantly (P<0.05) higher in Pearl than Lavender variety. The cut up parts in terms of thigh, breast and drumstick weight were significantly (P<0.05) higher in Pearl than the Lavender group. The organ weights in terms of gizzard weights were significantly (P<0.05)
higher in Pearl than the Lavender group. The blood picture revealed that the mean value of Hb was significantly (P<0.05) higher in Pearl than the Lavender variety. The mean values of total protein and globulin were significantly (P<0.05) higher in the Pearl than the Lavender variety
whereas albumin was significantly (P<0.05) higher in the Lavender than the Pearl variety. From the results of present investigation it can be concluded that Pearl has better performance than Lavender variety of guinea fowl.
