Aim:The main objective of the study was to determine the deleterious effect of fluoride on plasma trace minerals of fluorotic cattle and to evaluate the effect of Tamarindus indica leaf powder toward correction of the same.Materials and Methods:A total of 30 cattle exhibiting chronic sign of fluorosis and 10 healthy cattle from nonfluorotic area were incorporated in this study. Fluorotic cattle were divided into three equal groups consisting of 10 cattle each. Group I from fluoride free area served as healthy control. The Group II received no treatment and served as disease control. Groups III and IV were supplemented with tamarind leaf powder at 15 g and 30 g/day with feed for 60 days. Plasma mineral status was evaluated after 60 days of treatment with double beam atomic absorption spectrophotometer.Results:Statistical analysis of data revealed a significant (p<0.05) decrease in mean plasma copper (Cu) (0.344±0.007 ppm), zinc (Zn) (0.692±0.06 ppm), and iron (Fe) concentration (1.100±0.01 ppm) in fluorotic cattle in comparison to healthy cattle (0.58±0.010, 2.342±0.04, 1.406±0.04 ppm, respectively). Significant (p<0.05) increase in Cu, Zn, and Fe was recorded after supplementation of tamarind leaf powder to the fluorotic cattle.Conclusion:It was concluded that fluorotic cattle might be supplemented with T. indica leaf powder with feed for the correction of the decreased level of certain plasma minerals.

Aim:The study was conducted to determine the serum levels of certain hormones in post-partum anestrus cows following treatment with controlled internal drug release (CIDR) and Ovsynch protocol.Materials and Methods:A total of 30 postpartum anestrus cows were divided into three equal groups after thorough gynecoclinical examination. The Group 1 animals received an intravaginal progesterone device on day 0 and 2 ml of prostaglandin F2α (PGF2α) on day of CIDR removal (7th day), Group 2 cows were treated with ovsynch protocol (gonadotropin-releasing hormone [GnRH]-PGF2α-GnRH) on day 0, 7 and 9, respectively, and Group 3 cows were supplemented with mineral mixture and treated as control. The serum estrogen, progesterone, triiodothyronine, and thyroxine concentration were estimated using enzyme-linked immunosorbent assay kit and absorbance was read at 450 nm with Perkin Elmer Wallac 1420 Microplate Reader.Results:There was a significant increase in progesterone level in Group 1 after withdrawal of CIDR as compared to other two groups. However, the estrogen assay revealed a greater concentration in Group 2 against Group 1 on day 7 of sampling. However, there was no significant difference for serum triiodothyronine (T3) and thyroxine (T4) irrespective of treatment protocols and days of sampling.Conclusion:Treatment with CIDR based progesterone therapy and drug combinations may affect the reproductive hormonal balance like estrogen and progesterone, which is inevitable for successful return to cyclicity and subsequent fertilization and conception. However, as far as serum T3 and T4 concentration concerned it may not give an astounding result.

Aim:The objective of this study was to evaluate the effect of feeding fermented fish silage (FFS) on serum biochemical parameters of Japanese quails (Coturnix coturnix japonica).Materials and Methods:A total of 192, 7-day-old broiler Japanese quail chicks of either sex, were randomly distributed into four dietary treatments with four replicates in each group having 12 chicks in each replicate pen. The dietary treatments were T1 – Control diet, T2 – Diet containing 5% FFS, T3 – Diet containing 10% FFS, and T4 – Diet containing 15% FFS. Group body weight and feed consumption were recorded at weekly intervals. Feed conversion ratio (FCR) was derived by dividing the feed consumed with the weekly body weight gain. At the end of the experiment, 8 birds from each treatment were selected randomly and sacrificed by cervical dislocation to study the carcass traits expressed as % pre-slaughter live weight. At 5 weeks of age, about 2 ml of blood was taken from the jugular vein of each selected bird, and serum samples were separated after centrifugation. Total protein, albumin/globulin (A/G) ratio, calcium, phosphorus, triglyceride, total cholesterol, high density lipoprotein-cholesterol (HDL-C), very low density lipoprotein-cholesterol (VLDL-C), low density lipoprotein-cholesterol (LDL-C), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were estimated in the serum.Result:The cumulative body weight gains from 1 to 5 weeks of age did not vary significantly between control and 5% FFS group. However, a linear decrease in body weight gain was observed by increasing the levels of FFS beyond 5% in the diet. The cumulative feed consumption was significantly higher in case of birds under control group during 1-5 weeks of age as compared to birds fed FFS based diet (5%, 10%, and 15%). No statistical difference in cumulative feed conversion ratio could be noticed during 1-5 weeks of age. The eviscerated yield decreased and giblet weight increased due to the dietary supplementation of FFS at 15% level. The breast meat yield decreased due to dietary supplementation of FFS at 10% and 15% level in the diet of broiler Japanese quails. The effect of FFS was found to be nonsignificant (p>0.05) with respect to serum total protein, globulin and A/G ratio under different treatments whereas significant difference observed in serum albumin concentration. Dietary supplementation of FFS at 10% and 15% level significantly increased the AST concentration in serum. There was no significant difference among the treatments regarding the parameters such as ALT, calcium, phosphorous, triglyceride, total cholesterol, HDL-C, VLDL-C, and LDL-C.Conclusion:The serum-biochemical parameters are influenced by the dietary supplementation of FFS in broiler Japanese quails.

Through a survey in Kakatpur block, Odisha, twenty-one numbers of anestrous cattle were selected and equally divided in to three groups (T0, T1 and T2, n=7) for the experiment. T0 was kept as control (farmer's practice), while T1 and T2 were provided with area specific mineral mixture (Ca, P, Mn, Cu, Zn) at 50g/day/animal and bypass fat at 100 g/day/animal, respectively for 60days. Average daily gain was significantly higher in T1 and T2 as compared to that of T0. Significant improvement in blood glucose, cholesterol, triglyceride and SGPT status was observed after various treatments. Due to mineral supplementation, all blood mineral status was improved. T1 and T2 groups exhibited better ovarian status and conception rate after treatment. Although, highest conception rate was observed in T2 group. Therefore, it can be concluded that supplementation of mineral mixture and bypass fat improved reproductive efficiency of anestrous animals along higher daily gain.
