Incorporation of additives such as Cysteine hydrochloride and Ethylene diamine tetra acetic acid (EDTA) either in TEYFC or in EYC extender improved the post preservation quality of bucksemen. 2. Semen of Beetal bucks was superior at all the hours of preservation than that of Cross bred bucks.ThesisItem Open Access Effect of Nitrogen Phosphorus Potassium and PGR on Growth Yield Quality and Processing of Cape -Gooseberry (Physalis Peruviana Linn)(Birsa Agricultural University, Ranchi, 1988) Keshow Kumar Jha; B.P. JainStudies on the effect of four levels of nitrogen (60Kg, 80Kg, 100Kg and 120Kg/ha), three levels of phosphorus (50kg, 75kg, and 100 Kg/ha) and two levels of potassium (50 kg and 100Kg/ ha) and two levels of GA3 (20 and 40ppm) and ethrel (200and 300ppm) were made on growth, yield , quality and storage capability of cape gooseberry during 1991-1992 and 1992-1993 in the department of horticulture, Birsa Agriculture university kanke Ranchi. Higher dose of nitrogen (120Kg/ha) phosphorus (100 Kg/ ha) and potassium (100Kg/ ha) had shown promising effect on growth, yield and quality of cape- gooseberry. Jam can be stored upto 365 days at room temperature with very good taste in N3P3K2 treatment. In second experiment crop was grown with the recommended dose of N,P, K i.e 80:80:80 (singh et. al , 1977). Higher dose of GA3 (40ppm) gave 54.25q/ha and ehtrel (300 ppm ) gace 51.05q/ha whereas control gave only 48.50 q/ha. A yield of 74.18 q/ha was attained with the application of NPK @ 120, 100, and 100Kg/ ha in control with maximum cost : benefit ratio of 1:2.13.ThesisItem Open Access Some Aspect of Mastitis in Buffaloes(Birsa Agricultural University, Ranchi, 1987) Praveen kumar; Dr. A.K.SinhaHazarduous effect of mastitis on the socio-economic status of the farmers through the loss of milk and health of the animals leading to their culling and sacrifice is well established. With a view to asses the incidence and prevalence of mastitis in buffaloes in and around Ranchi in different farms with respect of daily milk yield, month of lactation, parity, types of infection and quarterwise infection by different indirect tests, the present investigation work was undertaken. To study these aspects of mastitis in buffaloes one organised farm, three unorganised farms and several private owners comprising the mixed group in and around Ranchi were taken for this study. Out of 259 milch animals 112 buffaloes were examined for incidence and prevalence of mastitis by indirect tests viz.trypsin inhibitor test, modified California mastitis test and bromothymol blue indicator card test and clinical observations were carried out to detect clinical, subclinical and chronic mastitis in these animals. To find out the causative organisms of mastitis and for their cure; culture, isolation, identification, sensitivity to different drugs, biological test for confirmations and drug trials for their treatment with different drugs were carried out in 29 buffaloes who were found positive for mastitis. Comparison of indirect tests for its suitability in detecting mastitis and efficacy of treatment for selection of drugs and line of treatment were carried out to have a better result of the research,ThesisItem Open Access Cumulative Effect of Long-Term Manuring and Fertilization On yield And Some of The Properties of An Acid Paleustalf Soil Under Irrigated Condition In Multiple Cropping System(Birsa Agricultural University, Ranchi, 1989) Shailendra Kumar Singh; B.S.MathurThe present project was undertaken to assess the changes brought out by the cumulative effect of manure, lime, sulphur and fertilizers, after 15 years of continuous application, on status of major nutrients, different forms of aluminium, phosphate fixing capacity etc. in surface and subsurface layers. The important findings are summarised below : 1.The fine particles in the surface and subsurface soil increased without affecting the textural class clay loam. 2. Fertilized soils were more reddish than the control and the colour did not change due to continuous cropping. 3. Acidity increased in surface and subsurface soil in fertilized plots and it was more in ammonium sulphate than the urea treated soil on equal nitro gen basis. Acidity increased with time. Treatment N was more acidic than NP and NPK. 4. With the increase in soil acidity all forms of Al also increased from the initial value in both the layers. 5. P-fixing capacity of soils increased with increase in soil acidity. 6. Organic carbon level of surface soil increased by 15.5 per cent over the initial value after 6 years of continuous application of FYM but decreased after 10 years. Use of chemical fertilizer lowered its level ranging between 4.9 and 29.6 per cent Organic carbon content in the surface was not affected. soil 7. Available N, P and K increased in surface and subsurface soils with passing of time. 8. Normal dose of NPK was better than subnormal or super-normal doses. Urea proved better than ammonium sulphate in increasing the yield of crops. 9. NPK was better than N, NP or PK in increasing the yield of crops.ThesisItem Open Access Studies on Maize Germplasm Complexes By Line X Tester Analysis(Birsa Agricultural University, Ranchi, 1986) Dilip Kumar Ganguli; D.P.SrivastavaPresent investigation was taken up to evaluate some newly developed germplasm complexes of maize for their future utilization in crop improvement programme. Eleven diverse germ plasm complexes used as females were crossed with three open pollinated heterozygous testers, of different genetic base, as males. Thirtythree cross combinations along with fourteen parents and one check variety were evaluated for two years for variability, heterosis and combining ability. The line x tester analysis for combining ability was done with crosses alone. Pooled analysis of variance components, combining ability variances and combining ability effects were done for twelve quantitative characters. Simple correlation and rank correlation was done to ascertain the association of parental performance and general combining ability effects and also for determining tester efficiency. The parents and crosses were found to differ significantly for almost all the characters in both the years. The mean values of the crosses were more than the parental mean of various characters. The phenotypic coefficient of variation was higher for grain yield, ear height, number of kernels/ear and 100-grain weight. Large number of crosses were found to give significant heterosis over mid-parent, better parent and over the check variety in majority of the characters. The manifesta tion of heterosis was strongest for some characters in the less favourable environment while for other characters a better envi ronment gave better heterotic effect.ThesisItem Open Access Studies on Some Aspects of Reproduction in Different Breeds of Pigs and Relationship between Reproductive performance and Blood Biochemical Profile(Birsa Agricultural University, Ranchi, 1987) Birendra Kumar Singh; Dr. B. K. SinghThe present investigation was conducted to compare the reproductive performance of three breeds of pigs viz. Large white Yorkshire, Landrance and Hampshire during three seasons. The relationship between reproductive efficiency and blood biochemical profile during different stages of reproduction was also studied. Furthermore, the changes in vaginal epithelium during different stages of oestrous cycle and pregnancy were observed using biopsy technique. 1. The average age at puberty in large white Yorkshire landrace and Hampshire was noted as 320.54, 1.95, 314.68, 1.62 and 316.52, 1.56 days. The influence of breed on attainment of puberty was significant (P-0.05). The influence of season on puberty attainment was also significant(p0.01) and gilts born during rainy season attained puberty earlier as compared to gilts born during winter and summer season. 2. The mean duration of oestrous cycle and average duration of oestrus did not differ significantly between breeds during different seasons. A significantly (p-0.01) higher occurrence of oestrus was recorded during winter (42.06 +0.47%) than summer (24.16=0.51) and rainy season (33.10 +0.49). 3. The mean duration of 1st, 2nd and 3rd stage of farrowing was 2.49 -.18, 2.27+.162 and 2.31 + 0.19 hours respectively. The total duration of farrowing was 5.46 +.628, 8.95 +.74 and 6.87 +.60 hours in large white Yorkshire, landrace and Hampshire respectively and the differences were statistically significant (P 0.01). The overall placental weight was 1.25 +0.54 Kg.ThesisItem Open Access Role of Reticuloendothelial System in the Immunopathology of Marek's Disease(Birsa Agricultural University, Ranchi, 1986) Madhurendu Kumar Gupta; Dr G. J. JhaIt can be concluded from this work that the macrophages or the RE system has a pivotal role in protection against MD. Its depletion reduces the immunity to MD and stimulation leads to protection almost as much as by the vaccination itself. It remains to be found out if the vaccine also acts in the same way as activation of the RE system by the inert substances. Another interesting finding was that the LAI test could help in detection of the birds resistant or susceptible to MD. But its efficacy can differ from age to age. Hence its utility appears to be more in the third and fourth month of age when the disease is more likely to develop.ThesisItem Open Access Comparative Histological and Histochemical Studies on the Liver of Black Bengal Goats ( Carpa Hircus ) and Chotanagpur Sheep(Birsa Agricultural University, Ranchi, 1987) Massarat Khan; Dr. J. PrasadThe liver capsule measured 28.08 in goat and 18.62 in sheep. It was surrounded by a layer of flattened mesothelial cells. It was composed of collagen, elastic and reticular fibras and occasional smooth muscle. The liver capsule indicated intense reactions for bound protein and DMA moderate to weak reactions for PAS positive substances, glycogen, bound lipid, acid mucopolysaccharides and calcium salts in both the species: however reactions for PAS positive carbohydrates and alkaline phosphatase ware of higher intensity in sheep, whereas, a negative reaction was noted for alkaline phosphatase in the liver capsule of goat. Reactions for natural fats, MA, acid phosphatase and ferric iron were found to be absent. Stromal connective tissue contained scanty amount of elastic, collegen fibres and abundant of reticular fibros. The fibroblasts vara comparatively more in the stronal tissues of the sheep. Stromal connective tissus showed intansa reactions for bound protein and DNA moderate to weak reactions for glycogen/ bound lipid, acid mucopolysaccharides and calcium salts in both goat and sheep. The PAS positive carbohydrates and alkaline phosphatase activity in the stromal connective tissus was of higher degree in sheep. Noutral fats, MA, acid phosphatase and forric iron were found to be absent in both the cases.ThesisItem Open Access Comparative Histological Histochemical Studies on Certain Sex-Related Endocrines of Normal and Vasectomized Male Goats(Birsa Agricultural University, Ranchi, 1987) Malay Kumar Roy; Dr. R.D. SinhaComparative histology and histochemistry of pitui tary gland, pineal body, adrenal gland, thyroid gland and Leydig cells of testes were studied in the normal and vasectomized male goats. The normal goats were grouped under prepubertal (3-4 months), circumpubertal (6-7 months) and postpubertal (10-18 months) animals. The prepubertal vasec tomy was done at 3 months of age while postpubertal vasectomy was conducted at the age of 9 months. From vasectomized goats, the tissues were collected after 1, 3 and 9 months of operations.
