Effect of Murraya koenigii and Aegle marmelos combination on resumption of fertility in anestrous goats.

Abstract Dutt, R., Mehrotra, S., Hoque, M., Shanker, U., Singh, G., Agarwal, S.K., Das, G.K. and Singh, S.K 2010. Effect of Murraya koenigii and Aegle marmelos combination on resumption of fertility in anestrous goats. J. Appl. Anim. Res., 38: 249–252. To examine the effect of combined treatment of Murraya koenigii (Curry leaf plant) and Aegle marmelos(Bel) on restoration of fertility in 14 anestrous goats, 50% ethanolic extract doses of both plants were extrapolated from rats (1000 mg kg−1) to goat using dose equivalent system and converted into powder form based on per cent yield. Half the goats (treatment group) were treated with leaves powder for nine d. Experimental goats were subjected to real time B-mode transrectal ultrasonographic scanning of ovaries and serum collection periodically to study the ovarian function in terms of follicular turnover and estrogen, progesterone profiles, respectively. An increase (P<0.05) in small (day 12), medium (day 12, 16), large (day 12) and total (day 12, 16) follicular population was observed in treatment group. Higher (P<0.05) concentrations of estrogen and progesterone were recorded on day 8, 12, 16 and 16, 20, respectively, in treatment group. 85% (6/7) of treated goats expressed estrus at mean interval of 5.33±0.60 d after end of treatment out of which 83.33% (5/6) were confirmed pregnant ultrasonographically. Results demonstrated favourable effect of plants combination on reproductive performance in anestrous goats.

Medicinal Uses of Murraya koenigii and Aegle marmelos for Fertility Augmentation in Animals: A Review

Ethno veterinary research has emerged as a fertile field for the generation (or regeneration) and transfer of appropriate and sustainable animal health technologies to rural and even peri-urban livestock raisers everywhere especially in the third world. Ethno veterinary practices still have significant contributions to animal health and are regarded as sustainable veterinary medicine in the new era (Lin et al., 2003). The prefix „Ethno‟ stands for traditional or indigenous and imbibes the knowledge passed on verbally from generation to generation. There cannot be any shadow of doubt on the poly valency of ethno veterinary medicines obtained from nook and corners of the world. The ethno veterinary practices, therefore, include all aspects of indigenous practices to prevent and treat a range of livestock diseases. As much as 90% of the world‟s population today still relies mainly on local ethno medicine for their health needs (Duke, 1992). Similar figures appear to hold for the livestock sector (McCorkle, 1998).

Ultrasonographic Assessment of Embryonic Mortality in Cows

Embryonic mortality (EM) is generally defined as loss of the conceptus which occurs during the first 45 days of pregnancy, which is the period from conception to completion of differentiation (Committee on Reproductive Nomenclature, 1972). Approximately 30% of pregnancies are lost in the form of embryonic demise and this increases the successive calving interval thereby ultimately affecting the success of reproductive programs in dairy cows (Chaudhary and Purohit, 2012). Early embryonic mortality is a major source of economic loss with mortality rate upto 40% in animal production through repeat breeding and increased cost of artificial insemination (Sareen and Diskin, 1986; Zavy, 1994; Bajaj, 2001) cost of treatment, extended calving intervals and prolonged dry period resulting in reduced milk production (Roche et al., 1981) and reduced net calf crop (Maurer and Chenault, 1983). The cost of losses to farmers due to embryonic mortalities has been estimated as high as 250 million per year in UK (Hensela et al., 1976). Although, it is clearly not possible to extrapolate these figures to the whole world as national International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 7 Number 06 (2018) Journal homepage: http://www.ijcmas.com
