The development and availability of follicles is an indicator to predict which of the follicle sizes are suitable to recover the oocytes assisted by means of ultrasonography of transvaginal oocyte retrieval (OPU). Thus, the study was done in order to characterize the follicular recruitment and distribution in response to the repeated removal of follicles, and thus to determine the availability of follicles and immature oocytes harvested repeatedlyfor two consecutive days of OPU in beef cows. Results indicated that 24-h OPU showed significantly greater numbers of medium and large follicles than small categories (P<0.05). However the 48-hr of OPU does not showed any differences of follicles categories (P>0.05). The mean total number of follicles and immature oocytes recovered were higher (P<0.05) in 24-hr OPU (13.76±1.2 and 7.38 ± 1.7) compared to 48-hr OPU (9.08 ± 1.5 and 3.54 ± 1.00) with the oocyte retrieval rate of 51.22% and 38.17%, respectively. The morphological classification indicated the 24-hr oocyte retrieval produced 62% of suitable immature oocytes that can be used for in vitro embryo production. In conclusion, the repeated removal of two consecutive days of OPU has averted the development of dominant follicle, and thus, gave an atmosphere to the subordinate follicles to continue growth relatively to an equal proportion of small, medium and large categories of follicles. Due to the reduction of follicle and recovery rate at 48-hr it is suggested that OPU be carried out later than 48 hour so that the follicle has more time to increase the diameter size.

This study was conducted with the aim of investigating the&#xD;effectiveness of Neem leaf extracts, Azaridachta indica, an indigenous medicinal plant, against helminths of goats. Two extracts were prepared with distilled water using two different techniques; that is, the Neem leaves Water Extract (NLWE) and decoction of Neem&#xD;leaves(NLD). This study was carried out using 20 goats from a government farm in Perak. The two extracts showed variable degrees of efficacy in naturally infected goats, as measured by faecal egg count. Further evaluation is required to establish the efficacy.

This study was done to evaluate the status of resistance to nematode populations on four major groups of anthelminthics. Nematode faecalegg count reduction tests (FECRT) were conducted on six free grazing small holder goat farms (namely Farms A-F) in Perak.The four drug groups tested in this study were Benzimidazoles, Imidazothiazoles,Macrocyclic Lactones and Salicylanilides. Faecal samples were subjected to the standard procedures of McMaster for worm egg estimation and also larval cultures for third stage larvae identification. Results of Farm A, Farm C and Farm D showed resistance to all 4 drugs groups of anthelminthic that were tested and the major worm population of this farm were Haemonchus contortus (49.75%), Trichostrongylus colubriformis (47.71%) and Cooperia sp. (2.53%). The results of Farm B and Farm F showed resistance to all the 3 groups of anthelminthics except Levamisole and the worm population of this farm was Haemonchus contortus (47.30%), Trichostrongylus sp. (38.44%), Oesophagostomum columbianum (13.50%) and Cooperia sp. (0.76%) Farm E was resistant to Benzimidazoles andsuspected resistance to 3 drugs groups; Levamisole, Macrocyclic Lactones and Closantel. The worm population for Farm E was Haemonchus contortus (71.35%), Trichostrongylus sp. (27.6%) and Oesophagostomum sp. (2%). These farms have a history of using the same anthelminthics over the past few years, thus leading to the severe case of anthelminthic resistance. Recommendations have beenmade to control helminths using alternative approaches such as cut and carry feeding, herbal medication using Neem leaves (Azadirachta indica) and rotational grazing as well as improvement in management of animals to increase their immunity.
