Experiment was conducted on 100 Gir cows of different parity and stage of lactation maintained at Ashti Dairy Farm, Ashti taluka Partur, district Jalna of Maharashtra state. The present experiment was carried out to know the effect of parities and stage of lactation on milk parameters <italic>viz</italic>; WeeklyMilk Yield (WMY), WeeklyFat CorrectedMilk Yield (WFCMY), Fatand Solid Not Fat (SNF) percent and correlation between Body Condition Score (BCS), Body Weight (BW) and body measurements viz; height at wither, height at hook, heart girth and body length with milk parameters. The Least Squares Analysis of Variance has revealed significant effect of parity on the WMY, WFCMY and Fat percentage whereas, significant effect of stages of lactation on the WMY and WFCMY of Gir cows. The positive to negative significant correlation coefficients of body condition score with WMY (0.110); Height at wither with WMY (0.131) and Fat percent (-0.156); Hearth girth with WMY (0.125) and Fat percent (-0.155) and Body length with Fat percent (-0.139) respectively.
The present study was carried out from the data obtained on the reproduction performance of 95 Tharparkar cattle over the period 1995-2014. The overall least squares mean and standard error for age at first calving, service period, gestation period, dry period and intercalving period were 1769.07± 29.80, 117.53± 2.39, 281.62± 0.37, 105.03 ± 2.09 and 399.97 ± 2.44 days, respectively. The Least Squares Analysis of Variance has revealed that there was a significant effect of sire ( P<0.01) and period (P<0.05) on age at first calving and the service period is significantly influenced by period and parity of the animal .Similarly the gestation period was affected by parity, dry period was affected by period of study and inter calving period was substantially influenced by period and parity of the animal. The observed correlation coefficients among different reproductive traits were significant to highly significant where as the estimates of heritability for the same traits were low to moderate. The significant effect of several non-genetic factors on most of the reproductive traits suggesting that they are low heritable and cannot be improved by conventional selection methods but can only be improved through effective management practices, nutrition, health etc..
Background: Subacute ruminal acidosis is one of the most important nutritional diseases in cattle. The consequence of feeding excessive amounts of rapidly fermentable carbohydrates in conjunction with inadequate fiber to ruminants leads to subacute ruminal acidosis. Cattles are at a high risk of developing SARA. The present research work was undertaken to study haemato-biochemical alterations in SARA affected cattle treated with different treatment regimens. Methods: Present work was done to study the efficacy of sodium bicarbonate powder, Azadirachta indica (Neem) dried leaves powder and Saccharomyces cervisiae (Yeast) in sub-acute ruminal acidosis (SARA) in cattle. Out of 148 cattle screened, 24 (16.22%) were diagnosed as SARA, 13 (56.52%) animals were in mid stage of lactation followed by early and late lactation (5 cases, 21.74% each).Result: After sodium bicarbonate treatment, animals showed changes in various haemato-biochemical parameters. However decreased neutrophils and ALT was also observed. After treatment of Azadirachta indica reduction in lymphocyte and eosinophil count was seen.
A study was conducted to estimate the draft performance and to aware farmer for working efficiency of Red Kandhari bullocks. Carting trials were carried out with pneumatic (C1) and iron cart (C2), on field (R1), kaccha (R2) and tar road (R3) with load of L1 (1000kg), L2 (750kg) and L3 (500 kg). The draft generated by bullock with combination of C2, L1 and R1 has given the highest draft of 141.18 kg, where as the combination of C1, L3 and R3 has given the lowest draft of 25.63 kg. combination of C1, L3 and R3 has given the highest speed of 5.66 km/hr, whereas; the combination of C2, L1 and R1 has given the lowest speed of 2.32 km/hr. Combination of C2, L1 and R1 has given the highest horse power of 1.21, whereas; the combination of C1, L3 and R3 has given the lowest horse power of 0.53. The overall performance of Red Kandhari bullock with pneumatic carts showed significant differences (P <0.01) and superiority compared to iron cart as far as the draft, carting speed and horse power were concerned.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
