Comparative Performance of Some Improved Poultry Crossbreds Under Konkan Region of India
ABSTRACT The experiment was conducted at Poultry Farm, College of Agriculture, Dr. B. S. Konkan Krishi Vidhyapeeth to assess the comparative performance of some improved poultry crossbred during laying period. The trial was carried out on five different types of improved poultry crossbred namely, -Giriraja x Delham Red (T1), Delham Red x White Leghorn (T2), Giriraja x Asselkala (T3), Delham Red x Giriraja (T4), Asselkala x Giriraja (T5) and two purebred groups like Delham Red and Vanraja. About 147 experimental birds were replicated three times and each replication consisted of seven birds in seven treatments in a Completely Randomized design. The feed consumption during early laying period and peak laying period differed significantly (P<0.05) between the groups. The average egg production was significantly (P<0.05) different in the treatments during early and peak laying period. The gross returns from the eggs of purebreds was significantly higher (P<0.05) than the crossbreds. It can therefore be concluded that, feed consumption is lower in purebreds than crossbreds. The average egg production is more in purebreds as compared to crossbreds up to peak laying period. Considering the minimum feed consumption and feed cost with maximum egg production and gross returns were observed in purebreds vis-a-vis crossbreds
Comparative Growth Performance of Deccani Lambs Under Various Rearing Systems in Agro-ecological Conditions of Konkan
ABSTRACT The experiment was carried out during winter season (Dec-March) to study comparative growth performance of Deccani lambs under different rearing systems. Twelve Deccani lambs of 3 months age were randomly allocated into three groups of four lambs each viz., T 1 (Grazing), T 2 (Semistallfed), T 3 (Stallfed). T 1 lambs were maintained on 6-7 hrs grazing (100%) with supplementation of concentrate mixture at night as maintenance ration. Both T 2 and T 3 lambs were reared on green roughages of green maize (Zea mays) and Shivan (Gmelina arborea) tree leaves with concentrate mixtures for maintenance. The dry matter intake, average daily gain in body weight, body length, body height, chest girth and total greasy fleece yield was significantly higher (P< 0.01) in stallfed system than grazing and semistallfed systems. The higher intake of dry matter in T 3 (Stallfed) lambs was observed than the lambs reared under the other two systems. Considering superior growth performance of Deccani lambs under stallfed system,present study concludes that , the sustainable lamb production could be promoted in stallfed (Intensive) system in Konkan region of Central India
Volume-6, Issue-2, EFFECT OF DIFFERENT RICE ESTABLISHMENT METHODS ON GROWTH, YIELD AND DIFFERENT VARIETIES DURING KHARIF SEASON
ABSTRACT: A field experiment was conducted in spit plot design with three replication to "Effect of different rice establishment methods on growth, yield and different varieties during kharif season" was conducted at Agronomy farm, College of Agriculture, Dapoli, Distt. Ratnagiri (M.S.) during kharif season of 2014 on was sandy clay loam in texture, moderately acidic in pH (5.63), medium in organic carbon content (0.82 %), electrical conductivity (Ec) 0.035 dSm -1 , medium in available nitrogen (284.82 kg/ha), low in available phosphorus (14.63 kg/ha) and high in available potassium (248.45 kg/ha). The treatments of the experiment were drilling methods of sowing rice seeds were sown by using manually with 15 cm row spacing as per seed rate (60 kg ha -1 ). In early transplanting (15 days age old seedling), transplanting as per as recommended (21 days old age seedling) and thomba methods transplanted seedling with 20x15 cm spacing with 3 to 5 seedling per hills. The other common packages of practices were followed time to time and periodically are observations were recorded on growth and yield for evaluate the treatment effects. The results obtained during the study revealed that grain yield of the different establishment methods were in the order, transplanting as per as recommended (21 days old age seedling at par early transplanting (15 days age old seedling)followed bythomba methods transplanted and drilling methods. The highest plant height (71.09 cm), effective tillers (360.58 m 2 ), length of panicle (21.07 cm), test weight (22.24 g), straw yield (47.42 q ha -1 ), dry matter (1371.92 m -2 ), weight of per panicle (2.15 g), number of filled grains per panicle (97.08) and B:C ratio (1:2.23) were recorded in line transplanting technique. Based on the results obtained, it can be concluded that in areas where labour is available and cheap, transplanting as per as recommended (21 days old age seedling) is a better establishment methods of rice because it produces more yield and gross monetary economic return than other methods
