Correlation Estimates of Some Performance Traits of Thari Cattle

The studies were carried out during the year of May 2014 to May 2015 to estimate the correlation among some performance traits of Thari cattle. The recorded data which include three sires with 15 daughters from each sire and four lactations of each daughters were observed. The averaged birth weight and weaning of three sires daughters was found 17.7 + 1.75, 17.38 + 1.01, 17.4 + 1.92 and 43.18 + 2.07, 42.6 + 2.49, 42.7 + 4.19, respectively. The result showed that higher birth weight was observed in daughters of sire- B whereas the lowest birth weight was found in daughters of sire- C and the higher weaning weight was found in daughters of sire- A and lowest weaning weight was found in daughters of sire-B. The milk yield of 1st, 2nd, 3rd and 4th lactation yield of all daughter were found averaged 861.60±70.40, 1046.78 ± 62.36, 1200.91 ± 111.21 and 1070.87 ± 54.56 liters, respectively. The result showed that 3rd lactation yield was significantly (P<0.05) higher than 1st, 2nd and 4th. The sire wise birth weight, weaning, milk yield and lactation length showed a non-significant different. The results of simple correlation for birth weight x weaning weight and milk yield x lactation length were 0.478 and 0.548. The result of environmental correlation for birth weight x weaning weight and milk yield x lactation length were 0.05 and 0.91. The results of genetic correlation for birth weight x weaning weight and milk yield x lactation length were -0.008 and -0.67. The results of phenotypic correlation for birth weight x weaning weight and milk yield x lactation length were 0.06 and 0.24, respectively.

Population Density of Grey Francolin (Franclinus Pondicrianus L.) in District Tando Allahyar, Sindh, Pakistan

The population density of Grey Francolin (Franclinus Pondicrianus L.) is distributed throughout the Baluchistan, KKPK, Punjab, and Indus plains of Sindh Province, Pakistan. The grey francolin is a prime game bird of our country. This species has been declared threatened worldwide according to the Red Data Book, also published by the International Union for Conservation of Nature in 2018. There is no information available regarding the density of the population of Grey francolin in different populations in the district of Tando Allahyar, Sindh, Pakistan. Keeping this in mind, the present study was carried out to find the density population of Grey francolin birds in the habitat area to observe the conservation measurements. The study was conducted through direct sighting with the help of local residents of the particular areas using the Visual Encounter Method. The observations were recorded at three fixed transects, with a length of 300 to 350 m and a width of 30 to 60 m laid down at every site for recording the birds by nearest line. In Tando Allahyar, Sindh, Pakistan, the population density of Grey francolin varies significantly based on breeding practices and habitat characteristics. The observed densities were 0.90 birds per hectare in cultivated open land and 0.16 birds per hectare in wetland and associated natural vegetation. This suggests a notable influence of habitat and breeding practices on Grey francolin population

Correlation Estimates between Carcass Traits of Nili Ravi and Kundhi Buffalo

Present study was designed to estimates the correlation between carcass traits of Nili Ravi and Kundhi buffalo.

Effect of Dextrose Sugar on the Growth and Production of Oyster Mushroom (Pleurotus ostreatus) through Tissue Culture

The study was conducted to investigate the dextrose sugar effect as carbon source on mycelial growth and production of Oyster mushroom (Pleurotus ostreatus). The experiment was performed in Mushroom Laboratory, Plant Pathology Section, Agriculture Research Institute, Tandojam, during 2013-2014. Mycelial growth was developed by using tissue culture on medium (PDA) potato dextrose agar with various concentrations of dextrose sugar. Analysis of variance for concentrations was statistically highly significant for all the parameters. In some cases among the different concentrations, 2.0% dextrose sugar showed after 2 days of micro propagation, the mycelial growth (1.9 cm) was recorded, followed by 1.5% dextrose sugar that showed (1.7 cm). The earlier spawn mycelia growth was observed in case of amending same 0/2% dextrose sugar (24.5 days). The pinhead first appeared (29.5 days) after the date of spawning by using 2.0% dextrose sugar. The minimum period (4.2 days) for maturation of mushroom fruiting body were recorded at 20% and 1.5% dextrose sugar. The maximum numbers of fruiting bodies (56.2) were observed with an application of dextrose sugar at 2.0%. The maximum number of bunches per bag (16.5) were harvested with an application of dextrose sugar 2.0%. The highest (350.5 g) fresh yield of Oyster mushroom Pleurotus ostreatus was recorded from 2.0% am ended of dextrose sugar
