The study was undertaken to evaluate the slaughter house goat ovaries, follicle and cumulus-oocytecomplexes (COCs) with the view of in vitro production of embryos. Goat ovaries were categorized as right, left, with corpus leutum (CL) and without CL group. Ovaries were then evaluated on the basis of weight (gm), length (cm), width (cm), total number of follicle on the surface of each categorized ovaries, number of follicle aspirated, total number of COCs, normal COCs and abnormal COCs. The length (cm) of right ovaries (1.19±0.09) was found significantly (p<0.05) higher than left ones (1.15±0.04). The number of normal oocyte was found significantly higher (p<0.05) in left ovaries (1.18±0.10) then right ovaries (1.11±0.09). Other parameters, including width, weight and total number of COCs aspirated per ovary did not differ significantly (P<0.05) between right and left ovaries. When compared the ovaries in between with-CL and without-CL group, significantly (p<0.05) higher number of normal COCs (1.12±0.07) were found in without-CL group with an increase of length (1.17±0.01), total number of follicles (5.21±0.03), number of aspirated follicles (2.74±0.12) and total number of COCs (1.99±0.14), but decrease in weight (0.66±0.03), width (0.76±0.02) and abnormal COCs (0.87±0.15) per ovary. Therefore, it could conclude that, both right and left ovaries is great source for large number of oocyte and without-CL ovaries is considered as a suitable source to supply quality oocyte for in vitro embryo production of goat.

The experiment was conducted to study the effect of treatment of rice straw with urea and a urease containing midden soil on the chemical composition of treated rice straw, feed intake of the animals, nutrients digestibility, body weight gain, feed conversion efficiency and overall economy of feeding for a period of 105 days. Twelve indigenous growing cattle (live weight 130.00 +/- 1.67 kg) were selected and divided into four groups having three animals in each group. The animals received 3.0% urea + 2.0% midden soil treated rice straw (group A), 3.0% urea + 3.0% midden soil treated rice straw (group B), 3.0% urea + 4.0% midden soil treated rice straw (group C) and 3.0% urea + 5.0% midden soil treated rice straw (group D). In addition, all the animals were supplied with 2 kg green grass, 450 g concentrate mixture and 40 g salt per 100 kg body weight. Treatment of rice straw with 3.0% urea + 2.0% midden soil lead to an increase in crude protein content from 3.30 to 7.08%, which was further increased by 7.40, 7.90 and 8.14% if treated with 3.0% urea + 3.0% midden soil, 3.0% urea + 4.0% midden soil and 3.0% urea + 5.0% midden soil, respectively. The total live weight gain by the end of the experimental period (105 days) was 39.00, 42.50, 46.50 and 49.00 kg for groups A, B, C and D respectively. The addition of 5.0% midden soil as a urease source with 3.0% urea (D) treated rice straw not only significantly (P<0.01) increased the coefficient of digestibility of dry matter (DM), crude protein (CP), crude fibre (CF), ether extracts (EE) and nitrogen free extract (NFE), but also significantly (P<0.05) increased the coefficient of digestibility of (OM) compared to treatment of rice straw with 3.0% urea + 4.0% midden soil (C), 3.0% urea + 3.0% midden soil (B) or 3.0% urea + 2.0% midden soil (A). Digestible organic matter (DOM), digestible crude protein (DCP), digestible crude fibre (DCF), digestible nitrogen free extract (DNFE) and total digestible nutrients (TDN) contents were significantly (P<0.01) higher in diet D, compared to diets A, B and C. Total profit of meat production in group D was significantly higher (P<0.01) than in groups A, B and C.

Twelve indigenous growing cattle (live weight 130.00 ± 1.67 kg) were selected and divided into four groups having three animals in each group. Group A, B, C and D supplied 3.0% urea + 2.0% midden soil, 3.0% urea + 3.0% midden soil, 3.0% urea + 4.0% midden soil and 3.0% urea + 5.0% midden soil treated rice straw. In addition to this all the animals were supplied 2 Kg green grass, 450 g concentrate mixture and 40 g salt per 100 kg body weight. Rice straw treated with 3.0% urea+ 2.0% midden soil resulted an improvement in crude protein content of rice straw from 3.30 to 7.08% which was further increased by 7.40, 7.90 and 8.14% treatment with 3.0% urea + 3.0% midden soil, 3.0% urea + 4.0% midden soil and 3.0% urea + 5.0% midden soil respectively. The addition of 5.0% midden soil as a urease source with 3.0% urea (D) treated rice straw not only significantly (P<0.01) increased the coefficient of digestibility of DM, CP, CF, EE and NFE but also significantly (P<0.05) increased the coefficient of digestibility of OM than other treatments. Digestible organic matter (DOM), crude protein (DCP), digestible crude fibre (DCF), digestible nitrogen free extract (DNFE) and total digestible nutrients (TDN) contents were significantly (p<0.01) higher in diet D in comparison to diet A, B and C.
