| Abstract | The experiment was undertaken to study the effect of collection techniques on cumulus oocyte complexes (COCs) recovery, in vitro maturation (IVM) and in vitro fertilization (IVF) of goat oocytes. COCs were collected by three techniques viz. puncture, slicing and aspiration of goat ovaries obtained at slaughterhouse. It was observed that, the total number of COCs/ovary as well as the number of abnormal COCs/ovary were significantly higher (p < 0.01) in puncture (4.22 and 2.38, respectively) and slicing (4.14 and 2.22, respectively) followed by aspiration (3.28 and 0.80, respectively) technique. In contrast, the number of normal COCs/ovary was significantly higher (p < 0.01) in aspiration (2.48) followed by slicing (1.91) and puncture (1.85) techniques. Only normal quality COCs were cultured in TCM-199 supplemented with 2.5% bovine serum albumin (BSA) plus 10% goat follicular fluid (gFF). The matured COCs were then fertilized in BO medium with fresh buck semen. The results showed that the rates of COCs that reached the maximum cumulus cell expansion (level-3) were 64.14, 65.93 and 65.73%; metaphase-II (M-II) stage were 57.75, 58.23 and 58.57%; normal fertilization (formation of male and female pronuclei) were 34.43, 35.03 and 34.65% in puncture, slicing and aspiration techniques, respectively; there were no significant differences among these rates. The results revealed that the collection techniques have no significant effect (p > 0.05) on in vitro maturation and fertilization of goat oocytes as long as normal quality COCs was used.Key words: Collection techniques, cumulus oocyte complexes (COCs), in vitro maturation (IVM), in vitro fertilization (IVF). |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
