The present study was aimed at assessing the effect of supplementing wheat flour with guava powder on physic-chemical and sensory characteristic of biscuits. Guava fruit was prepared as dehydrated powder and used at different levels (0, 2.5, 5, 7.5 and 10%) of wheat flour substitution for biscuit formulation. The effects of guava powder supplementation on physicochemical and sensory characteristics of biscuits were evaluated. Diameter of guava flour supplemented biscuits increased (from 4.72 cm to 4.86 cm) while spread ratio decreased (from 9.44 to 9.00), significantly. Protein (6.54% to 9.03%) and fiber (0.24% to 1.8%) also increased significantly by increasing the concentration of guava flour while moisture, fat and ash remain unchanged and NFE decreased. Sensory evaluation of biscuits showed that supplementation of guava flour improve color, texture, taste, aroma and over all acceptability. The supplementation seems to be suited for wheat flour substitution and it is possible to obtain biscuits of better quality within the standard for biscuits.

The aim of this study was to determine the effect of tocopherol and selenium on the performance of buserelin (GnRH analogue) for estrus induction in anestrus mares. A total of 18 seasonally anestrus mares were divided into three equal groups (n=6 in each) after ovarian scanning. Mares in group A (treatment group) were treated with tocopherol and selenium intramuscularly along with daily dose of buserelin. Mares which came into heat within ten-day buserelin protocol, further injections of buserelin for those mares were stopped. Mares in group B were treated with buserelin intramuscularly only for ten days. Mares which came into heat within ten-day buserelin protocol, further injections of buserelin were stopped. Blood/serum was collected from each experimental mare kept in different groups (A-C) at days 1, 11, 12, 13 and 14. Onset of estrus signs was 83.3, 33.3 and 0% in group A, B and C, respectively, that was significant (P<0.05) among groups. Follicular dynamics were 20.24±3.00, 14.59±2.24 and 10.35±0.63mm in groups A, B and C, respectively with significant (P˂0.05) difference. Change in serum E2 contents was significantly (P˂0.05) different among groups A, B and C whereas progesterone concentration showed non-significant difference among groups.
