ABSTRACT
The present study was aimed on the genetic improvement of non-descriptive goats through estrus synchronization and by crossbreeding with Beetal goats they were reported to be a good milker, having higher body weight and dressing percentage. AVIKESIL-S, indigenously developed progesterone intra-vaginal sponges were utilized for estrus synchronization in does maintained at livestock farm complex, Veterinary College, Hassan. Response to estrus synchronization was noticed in all the does (100%) under study, irrespective of the genetic background. Natural service was practised with three mating designs ie. G1-Beetal × Beetal, G2-Beetal × non-descriptive, G-3 non-descriptive × non-descriptive. Pregnancy test was performed with ultrasonography at 45 days post-mating. The conception rates in does of G1, G2 and G3 groups were 87.5, 87.5, and 75.0% respectively. Kidding rate were 85.7, 85.7 and 100.0% in G1, G2 and G3 groups, respectively. Litter sizes were 1.5, 1 and 1 in G1, G2 and G3 groups, respectively. Average birth weight in G1, G2 and G3 groups were 3.82±0.20, 2.82±0.12 and 2.00±0.09 kg, respectively and average daily gain in G1, G2 and G3 groups were 42.86±1.69, 33.81±1.28, and 33.57±0.87 g, respectively. Better growth performances were noticed up to 3 months of study period in G1 and G2 compared to G3 groups. It could be concluded that combined utilization of ES technology and crossbreeding in non-descriptive goats would provide superior kids for bulk marketing and ease management by avoiding dispersed kidding. Also more number of animals would be available for selection thus increasing the selection intensity their by improving the genetic improvement
ABSTRACT
Hypersensitivity is a common clinical multi-etiological problem. Many desensitizing treatments are there to overcome hypersensitivity. The aim of the study is to evaluate the effect of desensitizing dentifrice containing sodium calcium phosphosilicate and Diode laser on the tensile bond strength of composite to dentine. Materials and Methods: Thirty sound human molars were used. Enamel was wet abraded to expose flat dentin surfaces and polished with sandpaper. The specimens were then divided into three groups (n = 10) based on the type of dentin-desensitizing treatment given. Group 1- was the control group where no desensitizing agent was used. Group 2-was treated with desensitizing dentifrice containing sodium calcium phosphosilicate. Group 3- was treated with Diode laser. Afterwards, the desensitized specimens were treated with one step self-etch adhesive (Tetric N Bond) according to manufacturer's instructions and composite micro cylinders were packed. The specimens were then examined for tensile bond strength using universal tensile machine. Statistical analysis: The recorded values were subjected to statistical analysis using the SPSS software. One-way ANOVA, and Post-hoc Tukey HSD test were performed to evaluate the tensile bond strength values. For the entire evaluation, P < 0.05 was considered to be statistically significant. Results: Higher tensile bond strength was seen in the control group when compared with the experimental groups Conclusion: Based on the results of this study, dentifrice and Laser pretreated dentin has lower tensile bond strength with resin composites as compared to dentin that is untreated
