The present investigation was undertaken to study the morphological characteristics of foetal membrane of swamp buffaloes of Assam. Animals were calved normally and no cases of retention of placenta were recorded. The average expulsion time, weight, length, width and number of cotyledons of foetal membranes were 241.20+ 22.05 minutes, 3.47+0.12 kg, 171.87+ 2.99 cm, 30.83+ 0.73 cm and 114.83+ 5.56 respectively. A highly significant (P<0.01) positive correlation between birth weight of the calf and weight and width of the foetal membranes and a significant (P<0.05) positive correlation between birth weight and number of small cotyledons of foetal membranes were recorded in the present study. There was no significant effect of parity on various characteristics of foetal membranes except the number of large cotyledons. The number of large cotyledons was significantly (P<0.05) higher in animals of third to fifth lactation than in animals of first and second lactation. The sex of calves had no significant effect on various characteristics of foetal membranes.
Background: The experiment was conducted at farmer’s field to study the growth response and efficiency of feed conversion of Assam local goats under different systems of management.Methods: Twenty goats of one month of age were randomly selected in village Lachima of Nalbari district, Assam. The goats were randomly divided in two groups comprising of ten kids in each group viz, T0 (Control) where goats were reared under extensive system of management with traditional grazing and browsing and T1 (Experimental) where goats were reared under intensive system of management with ad lib. concentrate and fodder feeding. Conclusion: The average initial and final body weight of the goats during the experimental periods in T0 and T1 groups were recorded as 2.90±0.03 kg and 2.89±0.04 kg and 10.36±0.26 kg and 16.05±0.53 kg respectively with highly significant difference (P less than 0.01) from 3rd week of the experiment till the end of the experiment. The overall changes in body measurement showed highly significant difference between the groups. The feed conversion efficiency on DM basis was recorded as 3.49 in the treatment group. Due to significantly higher growth rate in the intensive management system, it assures higher income in small holders’ goat production system.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
