Abstract
The poultry industry generates a lot of waste, including dead birds, manure, and poultry litter. Poultry waste should never be disposed of improperly because it can seriously harm the environment. The waste can be recycled as a feedstock for use in poultry feed by composting the litter and deceased birds. The compositional profile and organoleptic properties of the meat of growing Japanese quail were examined over the course of a 4-week trial to ascertain the effect of adding compost to the diet. In a completely randomized design (CRD), 1200 newly hatched quail chicks (Coturnix coturnix japonica) were divided into five treatment groups (diets with 0, 2.5, 5, 7.5, and 10% compost), each consisting of 40 birds with six replicates. The addition of compost to the diet had no noticeable effects on the organoleptic qualities of appearance, color, aroma, taste, texture, juiciness, tenderness, and acceptability (P>0.05). The compositional profile characteristics for chicks given compost at any level compared to chicks fed the control diet showed no differences (P>0.05). These findings suggest that the sensory characteristics and compositional profile of growing meat quails can be maintained when fed diets including up to 10% compost.

Abstract
Large amounts of waste, including dead birds, manure, and poultry litter, are produced by the poultry industry. Poultry waste should be disposed of properly to avoid major pollution and health risks. Composting litter and dead birds could be an option to recycle the waste and use in poultry feed. A study was conducted to investigate the effects of feeding composted poultry waste on the organoleptic qualities and compositional profile of the meat of broiler chickens. A total of 300 day-old broiler chicks (500-Cobb) were randomly allocated to five treatment groups replicated six times with 10 birds each, under a completely randomized design (CRD). Five iso-caloric and iso-nitrogenous diets including composted poultry byproducts at concentrations of 0, 2.5, 5, 7.5, and 10% were fed ad libitum to the birds from day 0 to day 35. The sensory grading and meat composition profile of 500 Cobb broiler chickens were tested at 35 days of age. The findings showed that there were no variations in the sensory profiles of the meat from birds given various diets (P>0.05). Although the results were somewhat lower for the chicks fed compost-containing diets than for the control group, this difference was deemed to be insignificant (P>0.05). Similarly, there were no variations in the compositional profile values of the meat between meat from birds fed various diets (P>0.05). These findings imply that broiler chickens may be raised on diets containing up to 10% poultry byproduct compost without any negative impacts on the meat's sensory quality or composition. Additionally, using compost into broiler diets may help to lower the cost of feed.

Abstract
The study was aimed to identify different environmental factors (selected organochlorine pesticides) affecting the river water of Satluj. River Sutlej is about 1400 kilometers long and its water is extensively used for irrigation in Punjab, located both in India and Pakistan, which was also a reason of dispute between both countries for its water share. The study area was divided into four zones, Sulemanki Zone, Islam Zone, Mailsi Syphone Zone and Panjnad Zone. Liquid Liquid Extraction (LLE) technique was used for the collected water samples followed by high performance liquid chromatography (HPLC) UV-Visible detector The current finding revealed that aldrin was not detected during summer period in water samples of SZ-1 (Sulemanki Barrage), SZ-2 and SZ-3 (Maisli Siphon) of the study area. Lindane and DDE were found more in the samples of sediments from the study area at SZ-4 ranging from 2.238-8.226 ppb and 4.234-6.876 ppb, respectively. Heaptachlor (in sediments) was found to be0.032-234 ppb only at SZ-4.Endosulfan concentrations in water (winter) at SZ-3 was 0.06 ppb and at SZ-4,it was 0.05 ppb; dieldrin in water (winter) at SZ-4 was 0.0314 ppb and heptachlor was detected at SZ-1 (0.0315 ppb) and SZ-2 (0.0310 ppb) in water during winter season, were reaching to the Maximum Concentrations Limits (MCL), while all other residues investigated were found below the MCLin all the compartments of the study area set by various agencies like WHO/FAO- Codex Alimenterious. Present findings revealed that although the organochlorine pesticides are banned for agricultural use in many countries, including Pakistan, their presence in various samples might be due to illegal use of these pesticides in the study area and its neighboring regions. The overall study area comprises of mainly urban, suburban and agricultural land being the largest cotton growing area of the country. There is a need to take serious steps to minimize water pollution caused by pesticides to achieve a healthy lifestyle.

Abstract
Abstract In the developed countries, the use of OCPs (organochlorine pesticides) has been banned. However, in South Asia several of them are still in use. In Pakistan and India a constant addition of OCPs into the atmosphere has been indicated by various researchers. In this study levels of selected organochlorine pesticide residues were assessed in sediment and biota collected from four (4) water reservoirs (3 Barrages & 1 Siphon) on the River Satluj Pakistan, along 231 miles (372 km) of River stretch which was further divided into 12 sampling sites. It was aimed to find out the levels of organochlorine pesticide (OCPs) residues in sediments and from selected fish species (Labeo rohita, Wallagu attu, Cyprinus carpio) of the River Satluj Pakistan. The Organochlorine residues (seven pesticides) present in samples of sediments and biota were investigated through multi residue method, using Gas Chromatograph (GC-ECD).In the current study, the concentration of DDT, was investigated in Wallago attu (0.786-3.987 ppb), Labeo rohita (0.779-4.355 ppb) and Cyprinus carpio (1.234-5.654 ppb). DDE was also found in Cyprinus carpio (1.244-6.322 ppb), Wallag attu (0.877-4.221 ppb) and Labeo rohita (2.112-5.897 ppb). Aldrin was not observed in Labeo rohita and Wallago attu. Currently, lindane and DDE was found predominately high in the sediments of study area at SZ-4 (Panjnad Barrage) ranging (2.238-8.226 ppb) and (4.234-6.876 ppb), respectively. Heaptachlor was found only at SZ-4 (Panjnad Barrage) from the sediments with concentration ranging (0.032-234 ppb). In short all other residues investigated were found below the MCL (maximum concentration level) in all the compartments of the study area set by various agencies like WHO/FAO- Codex Alimenterious.

Abstract
The present study was conducted to assess the growth performance, morphometric traits, muscle chemical composition and cholesterol content in four phenotypes of naked neck chicken (black, white-black, light brown and dark brown). A total of 320-day-old chicks, 80 from each phenotype, were randomly stratified into 20 replicates (16/replicate), according to a completely randomized design. The results showed higher final body weight, weight gain, and better FCR in both light brown and dark brown phenotypes whereas time of gains was found to be greater in dark brown phenotype. Keel length and shank circumference were greater in dark brown whereas wing spread was found to be higher in light brown phenotype. Drumstick circumference and body length did not show any significant differences (P > 0.05) across the phenotypes. Dry matter was found to be higher in white black, crude protein in black, white black and dark brown, moisture in light brown, and cholesterol content in black whereas ether extract and ash content were found to be greater in black and white black phenotypes. In conclusion, both light brown and dark brown phenotypes showed superior growth performance and morphometric traits. Similarly, from a health point of view, the dark brown and light brown phenotypes seem superior because their cholesterol content was low. Thus, it is strongly recommended that there should be a conscious effort to improve economically important traits of the light and dark brown birds to be used as dual-purpose slow growing chicken, especially in developing countries.

Abstract
During the present study thirteen Megaderma lyra bats were observed roosting in dark, domed shaped room of Rohtas Fort, district Jhelum. Out of these, six specimens were captured from the roosting site, using hand net. All captured specimens were male. These bats were identified through their unique facial features, an erect and elongated nose-leaf, large oval ears that joined above the forehead and no tail. Mean head and body length of captured specimens was 80 mm, forearm length was 67 mm while average lengths of 3rd, 4th and 5th metacarpals were 51.73 mm, 55.17 mm and 60.42 mm, respectively. Mean skull length was 29.84 mm, breadth of braincase was 12.77 mm. Average Penis length of two specimens was 6.6 mm and total bacular length was 3.08 mm respectively. This is the first record of Megaderma lyra from district Jhelum.

Abstract
![]()
Photodissociation
of vibrationally and electronically excited sulfur
dimer molecules (S2) has been studied in a combined experimental
and computational quantum chemistry study in order to characterize
bound-continuum transitions. Ab initio quantum chemistry calculations
are carried out to predict the potential energy curves, spin–orbit
coupling, transition moments, and bound-continuum spectra of S2 for comparison with the experimental data. The experiment
uses velocity map imaging to measure S-atom production following S2 photoexcitation in the ultraviolet region (320–205
nm). A pulsed electric discharge in H2S produces ground-state
S2 X3Σg–(v = 0–15) as well as electronically excited singlet
sulfur and b1Σg+(v = 0, 1), and evidence is presented for the production and photodissociation
of S2 a1Δg. In a previous paper,
we reported threshold photodissociation of S2X3Σg–(v = 0) in
the 282–266 nm region. In the present study, S(3PJ) fine structure branching and angular
distributions for photodissociation of S2 (X3Σg–(v = 0), a1Δg and b1Σg+) via the B″3Πu, B3Σu– and 11Πu excited states are reported. In addition, photodissociation
of the X3Σg–(v = 0) state of S2 to the second dissociation
limit producing S(3P2) + S(1D) is
characterized. The present results on S2 photodynamics
are compared to those of the well-studied electronically isovalent
O2 molecule.

Abstract
An optimized laser-induced breakdown spectroscopy (LIBS) system was utilized as a robust tool for the detection of high toxic lead (Pb) in often used edible colors available in local markets. Edible colors are extensively used in different food stuffs and sweet dish items. To attain a highly sensitive LIBS system for the determination of trace amounts of toxic Pb in edible colors and to achieve the best detection limit, various parametric dependence studies were performed. The quantitative determinations were accomplished under the condition of local thermodynamic equilibrium in terms of optically thin plasma. Besides toxic Pb, other elements like Ca, Mg, Fe, and Na were also detected in edible colors. To estimate the concentration of toxic lead in edible colors, calibration curves were plotted by preparing standard samples of different lead concentrations in an edible colors matrix. Results of the LIBS technique were compared with the outcomes of the same samples studied using a standard analytical technique of inductively coupled plasma-optical emission spectroscopy to confirm the contemporary LIBS setup. The color samples were found above the safe permissible level due to the mass of toxic lead. Limit of detection of the LIBS setup was found at 0.86+/-0.03 ppm for toxic lead present in edible color samples.

Abstract
A spectrometer based on pulsed nanosecond laser-induced breakdown spectroscopy (LIBS) was employed for the quantitative determination of heavy and essential metals in salts from various sources available in Pakistan. Six salt samples were collected from sea salt and rock salt. Toxic metals (Cu, Cd, and Ni) and other microessentials (Fe, Ca, Co, Mg, Mn, S, and Zn) were investigated from the recorded spectra. The detection system was calibrated using a parametric dependence study. The quantitative analyses were accomplished under the assumption of local thermodynamic equilibrium and optically thin plasma. The results by the LIBS technique were in agreement with the outcomes of the same samples studied using a more standard approach like inductively coupled plasma-atomic emission spectroscopy (ICP-AES). When the concentrations of heavy and essential metals were calculated using a calibration-free LIBS method that does not need a standard salt specimen and dilution, both LIBS and ICP-AES were also in good agreement. The limit of detection of the experimental set up was determined for the observed heavy metals in the studied samples.
