AICRP, on Black Bengal Goat, Department. of ABG, College of Veterinary Science and Animal Husbandry (BAU) Kanke, Ranchi-6 Jharkhand.(India) Received : 02.09.2011 Accepted : 29.03.2012 A total number of 18 does, which had kidded at least once and were found positive for common intestinal nematodes, were treated with Albendazole (Helmigard) @ 5mg/kg body weight orally along with a supportivetherapy of mineral mixture (Calvimin) @ 10 gm orally daily for 20 days. Six goats were kept as untreated control.
The minimum interval from treatment to onset of estrus in does was recorded in Albendazole + Mineral mixturegroup (43 days) which was followed by Albendazole group (46 days) and control group (52days), the averagerequired number of services per conception in does were 1.33, 1.00 and 2.00, respectively. The pregnancy ratesin the three groups were 66.66, 83.33 and 33.33%, respectively in case of does. The Albendazole along withMineral mixture can be administered to the parasitized goats to improve their reproductive performances.
Key words: Albendazole, Mineral, Nematodes, Estrus and Does.
The goat husbandry plays a significant role in the The present study was conducted to see the effect national economy. Inadequate nutrition coupled with high of intestinal parasites on reproductive performance of level of parasitic infection contribute to high reproductive does. For this a total number of 18 does which had and productive wastage in small ruminants. Apart from kidded for at least once and were found positive for this, intestinal helminthes cause significant reduction common intestinal nematodes were utilized and allotted in efficiency of nutrient utilization (Coop and Angus, to three groups viz. T , T and T , each group having 6 1975), poor calcium and phosphorus retention (Sykes animals.
