M.The research work entitled ‘Effect of Dry Period on the Subsequent Production and Reproduction Performance in Holdeo (Holstein Friesian x Deoni) Straightbreds’ was conducted for present investigation. It involves investigations of productive and reproductive characteristics viz,, Lactation milk yield. Peak milk yield. Days to reach peak milk yield, Lactation period. Dry period. Service period, Gestation period and Inter calving period. The study included 20 years data (1976-1995) on total number of animals 223 Holdeo straightbred cows. The overall least squares means were recorded for LMY (1491.58 ± 21.62 kg), PMY (7.12 ± 0.02 kg), DRPMY (35.82 ± 0.16 days), LP (288.58 ± 2.14 days), DP (141.24 ± 1.52days), SP (156.96 ± 2.49 days), (273.77 ± 0.06 days) and ICP (429.43 ± 2.44 days). The LMY, PMY,LP, DP, SP, GP and ICP in Holdeo cow was not significantly affected by period of calving, season of calving and lactation order and dry period. The DRPMY was significantly affected by lactation order and dry period (P < 0.05) in Holdeo straightbred cows. However, period of calving and season of calving had non-significant effect on DRPMY. Overall least squares means of DP in Holdeo cow was 141.24 ± 1.52 days. The effect of period of calving on GP was significant (PO.01), however, season of calving lactation order and dry period was non significant effect on GP. Overall least squares means for GP in Holdeo cows was 273.77 + 0.05 days. Only period of calving had significant (P < 0.01) effect on GP.ThesisItem Open Access Studies on reproduction and production characteristics of buffaloes at organized farm(Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani, 42154) Pendor, Vipinkumar Khushalrao; Thombre, B. M.The study was conducted for Murrah, Surti and Jaffiabadi buffaloes, entitled “Studies on Reproduction and Production Characteristics of Buffaloes at Organized Farm” in total data on reproduction and production characteristics of Murrah, Surti and Jaffiabadi buffaloes were 76, 47 and 06 animals respectively. Data were collected by evaluating the actual records of each individual animal at Department of Animal Husbandry and Dairy Science, College of Agriculture, Vasantrao Naik Marathwada Krishi, Vidyapeeth, Parbhani, (M.S).The results obtained from this investigation for Murrah buffaloes were AFC, SP, ICP, LMY, PMY, DRPMY, LP and DP as 1510.12 ± 38.37, 205.35 ± 7.03, 515.35 ± 7.03, 877.29 ± 45.59, 6.05 ± 0.15, 44.51 ± 1.89, 305.89 ± 7.13 and 212.18 ± 9.42 respectively. The results obtained from this investigation for Surti buffaloes were AFC, SP, ICP, LMY, PMY, DRPMY, LP and DP as 1781.22 ± 40.18,217.78 ± 6.94, 527.78 ± 6.94,. 809.59 ± 44.87, 5.51 ± 0.15, 44.27 ± 1.41, 315.32 ± 6.53 and 223.64 ± 9.11 respectively. The results obtained from this investigation for Jaffiabadi buffaloes were SP, ICP, LMY, PMY, DRPMY, LP and DP as 206.72 ± 22.96, 516.72 ± 22.96, 1912.30 ± 116.86, 8.16 ± 0.46, 43.77 ± 0.76, 334.83 ± 52.25 and 181.66 ± 39.64.In present investigation we found lowest AFC, SP and ICP in Murrah Buffalo as compared to Surti and Jaffiabadi buffaloes. The highest LMY, PMY and LP and lowest DRPMY and DP were found in Jaffiabadi Buffalo as compared to Murrah and Surti Buffaloes.ThesisItem Open Access Comparative performance of production and reproduction traits in red Kandhari and jersey X red Kandhari cross-bred cows(Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani, 1990) Atharkar, Arunkumar Ambadasrao; Sakhare, P.

R.The present investigation entitled ‘Teeding and management practices of crossbred cattle in Osmanabad district” was undertaken to study the different package of practices followed for crossbred cattle. Twenty villages from Osmanabad district were selected with the objectives to enumerate breeds in terms of age, sex in population of crossbred cattle, to study feeding practices crossbred cattle, to determine existing management practices and to study the constraints in feeding, management practices. The data was collected from the 200 respondents in Bhoom tahsil. The study revealed that die crossbred cattle is mostly used for the milch purpose. The population of females was more than that of male. Average lactation milk yield and lactation period were 2830.80± 42.35 (kg), 280 ± 5.18 (days), respectively. Average dry period recorded was 78.30 ± 2.06 (days), while the calving interval recorded was 358.30± 928(days). Open and kaccha housing pattern was followed in almost all cases. Additional ration for pregnant animals were given by very few number of farmers. Cent percent farmers adopted health and sanitation measures as cleaning of milking utensils, cleaning of hands and washing of udder before milking. Vaccination schedule was followed nearly about 83.50 per cent Green fodder is mostly available in Kharif and Rabi season It is also available in summer, where there is ample quality water is available, as most of the area in Bhoom was dry land. Grazing + stall feeding was adopted as method of feeding by majority of the respondents. There was very few farmers who adopted urea treatment and silage preparation Inadequate availability of green fodder, high cost of fodder and inadequacy of own grazing land are some feeding constraints. While production and marketing constraints includes low rate of milk, unavailability of credit for purchasing animals, irregular milking of cow and uncomfortness of animals in summer season. Whereas technical problems include nonavailability of labourers, unavailability of veterinary care hospitals and lack of knowledge about sterilization of cattle shed. Also lack of extension education facilities for educating farmers on scientific.feeding and management of cattles was observed.ThesisItem Open Access Productive and reproductive performance of murrah buffalo breed on organized farm(Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani, 40633) Dhaigude, Priyanka Narayan; Thombre, B. M.The study was conducted for Murrah buffalo, entitled “Productive and Reproductive Performance of Murrah Buffalo Breed on Organized Farm.” In total, data on productive and reproductive performance of 213 Murrah buffalo were collected by evaluating the actual records of each individual on Chitale Dairy Farm, Bhilwadi, Tal. Plus, Dist. Sangli. The results obtained from this investigation revealed that the LMY, PMY, DRPMY, LP, DP, Fat per cent, SNF per cent, AFC, SP, ICP and BE were as 1865.34 ± 10.83 kg, 8.45 ± 0.60 kg, 42.52 ± 0.25 days, 287.96 ± 0.34 days, 161.27 ± 0.30 days, 7.17 + 0.14 per cent, 9.24 per cent, 1522.45 ± 1.90 days, 138.99 ± 0.34 days, 449.12 + 0.56 days and 75.72 per cent respectively. The R observed were 0.47 ± 0.12, 0.18 ± 0.09, 0.19 ± 0.08, 0.21 ± 0.09 and 0.20 ± 0.09 for LMY, LP, DP, SP and ICP, respectively. From the above the study it could be concluded that Murrah genotype dose not adapted to the seasonal changes. There is urgent need to correct the management as period effect affects the Murrah genotype. The management factor had indirectly affected the productive and reproductive performance. The period effect which is basically of non-genetic origin contributed to certain extent in the manifestation of the production and reproductive characteristics. All though the data is on small herd of Murrah individuals but has given firm guidance for manipulation of non- genetic components efficiently while deciding about future selection and breeding programme. The periodic census for evaluation of Murrah buffalo is required. The performance recording of the Murrah buffalo under organized farm conditions is an important aspect to cover up genetic improvement.
