Resumo Os faisões estão diminuindo em todo o mundo, por isso informações atualizadas sobre sua população e seus habitats são importantes para conservação e manejo. O presente estudo foi realizado no vale Palas, distrito de Kohistan, Paquistão, no final da primavera (maio e junho) de 2020 e início da primavera (março e abril) de 2021 para avaliar a população e o estresse antropogênico. O foco principal foram três espécies simpátricas de faisão, incluindo Tragopan de Chifres Ocidental (Tragopan melanocephalus), Monal-do-Himalaia (Lophophorus impejanus) e Faisão Koklass (Pucrasia macrolopha). Foi utilizado o “Método de Contagem de Chamadas” para avaliar a população em campo, e foi realizada uma pesquisa por questionário para documentar a avaliação de risco dos moradores locais do vale. As avaliações populacionais revelaram que o Faisão Koklass está mais adaptado às crescentes atividades antrópicas e que sua população se mantém mais ou menos semelhante à população de 22 anos atrás. Nos últimos 22 anos, Tragopan de Chifres Ocidental e Monal-do-Himalaia perderam cerca de 40 a 50% de suas populações. A interferência humana, sob a forma de caça ilegal, desmatamento e sobrepastoreio, era comum no vale. O estudo conclui que o habitat do vale Palas é ideal para espécies de faisão; no entanto, a interferência humana, por meio de urbanização, fragmentação de habitat, caça ilegal e desmatamento, está ocorrendo em ritmo acelerado, causando estragos na população de faisões.

Abstract Pheasants are declining everywhere in the world and therefore updated information about their population and habitats are important for conservation and management. The present study was conducted in the Palas Valley, District Kohistan, Pakistan in late spring (May and June) 2020 and early spring (March and April) 2021 to assess the population and anthropogenic stress. The major focus was on three sympatric pheasant species, including Western Horned Tragopan (Tragopan melanocephalus), Himalayan Monal (Lophophorus impejanus), and Koklass Pheasant (Pucrasia macrolopha). We used the “Call Count Method” for the population assessment in the field, and a questionnaire survey was conducted to document the risk assessment of local residents of the valley. The population assessments revealed that the Koklass Pheasant is more adapted to increasing anthropogenic activities and its population appeared more or less similar as 22 years ago. In the past 22 years, Western Tragopan and Himalayan Monal have lost about 40–50% of their populations. Human interference in the form of illegal hunting, deforestation, and overgrazing was found to be common in the valley. The study concludes that the Palas Valley habitat is ideal for pheasant species; however, human interference in the form of urbanization, habitat fragmentation, illegal hunting, and deforestation is occurring at a rapid pace, causing havoc in the pheasant population.

ABSTRACT The purpose of this study was to assess the impact of a blend of essential oils from eucalyptus, citrus, bromohexene HCl, thymole and camphor on the growth performance, carcass characteristics, meat quality, intestinal morphology, serum biochemistry, and immune response of broiler chickens. A total of 240 day-old chicks were divided into four groups, each with six replicates containing ten birds. The experiment was conducted under a completely randomized design (CRD). Different concentrations of the oil blend (0mL/kg, 0.15mL/kg, 0.30mL/kg and 0.45mL/kg) were added to the diet. The findings showed that, in comparison to the other groups, the birds that were given a blend of essential oils at concentrations of 0.30 and 0.45 mL/kg showed improved weight gain, feed efficiency, carcass yield, villus height, crypt depth, and greater immune response against Newcastle disease vaccination (p<0.05). Nonetheless, there was no statistically significant difference in the yields of the breast and thighs, feed consumption, mortality, weights of the liver, wing, heart, and gizzard, or abdominal fat between the treatments. The addition of a blend of essential oils at the doses of 0.30 and 0.45 mL/kg significantly lowered the pH of the meat in comparison to the other groups (p<0.05). All blood biochemical markers, including total serum protein, albumin, globulin, glucose, cholesterol, triglyceride, and uric acid, revealed no variations between the treatments. In conclusion, adding 0.30mL/kg of a blend of essential oils to broiler diets may be the optimum level to improve overall performance without adversely affecting the blood biochemical profile. eucalyptus citrus HCl characteristics quality morphology biochemistry chickens 24 dayold day old CRD.

ABSTRACT The objective of this study was to evaluate the effect of eubiotics on the intestinal morphology of broilers. For this purpose, 125 birds were divided into six groups with two replicates each (10 birds in each replicate). Group A was given a Basal diet. All groups except group A were challenged with Salmonella enterica serovar Enteritidis. Group B was provided the basal diet, group C was fed a Probiotic-added diet; group D was fed a Prebiotics-based diet; group E was given essential oils plus the basal diet; and group F was provided with organic acids plus the basal diet. Two separate experiments were carried out for Salmonella recovery, checking the cecal tonsils and conducting an intestinal pathomorphic evaluation. Villus length, villus width, villus surface area, and crypt depth were measured by micrometry. There was an overall improvement (p<0.05) in intestinal morphometric parameters for all the treatment groups except for the negative control group, which showed the lowest villus height and villus depth values. Maximum villus height (p<0.05) of the duodenum was achieved by group E, which was fed a diet containing essential oils, whereas a maximum villus surface area index (p<0.05) was recorded for the birds of Group D, which were fed a diet containing prebiotics. Maximum villus height (p<0.05) and surface area index in ileum mucosa was recorded (p<0.05) in the birds of group D (treated with prebiotics). It is concluded that there is an overall increase in the gut histology of broilers fed non-antibiotic based feed. purpose 12 10 (1 replicate. replicate . replicate) Enteritidis Probioticadded Probiotic added Prebioticsbased Prebiotics recovery evaluation length width micrometry p<0.05 p005 p 0 05 (p<0.05 values prebiotics treated prebiotics) nonantibiotic non antibiotic feed 1 ( p<0.0 p00 (p<0.0 p<0. p0 (p<0. p<0 (p<0 p< (p< (p

Resumo A tecnologia Biofloc é muito destacada hoje em dia por causa de seus tremendos efeitos na aquicultura. Os micróbios foram enriquecidos com a fonte de carbono orgânico mais barata, i. e., cascas de banana em pó, e foram incorporadas em diferentes aquários de criação de alevinos de carpa-capim sob diferentes tratamentos C/N (10: 1, 15: 1 e 20: 1) e 10% de troca diária de água. O crescimento inicial dos alevinos foi registrado. O experimento foi resolvido em triplicatas por 60 dias e executado paralelamente ao grupo controle fornecido com ração comercial e troca diária de água. Seu efeito foi avaliado medindo o crescimento dos alevinos e os parâmetros da água de cada aquário. O% de ganho médio em peso e comprimento dos alevinos foi obtido significativamente mais alto (28,12 ± 0,30g e 17,29 ± 0,46 cm respectivamente) em aquários contendo cascas de banana em pó puro com 10% de troca de água e a relação C/N foi ajustada em 20: 1 (T3) do que outros tratamentos e controle. A amônia e outros parâmetros da água também estavam sob controle no T3 mais do que nos outros grupos experimentais e de controle. Por todas as contagens, concluiu-se que a maior razão C/N no sistema de bioflocos tem o potencial de incrementar a taxa de crescimento de C. idella reduzindo a toxicidade e pode ser usada como substituto da farinha de peixe.

Abstract Biofloc technology is much highlighted these days because of its tremendous effects on aquaculture. Microbes were enriched on cheapest organic carbon source i. e., powdered banana peels and were incorporated in different aquaria rearing grass carp fingerlings under different C/N treatments (10:1, 15:1 and 20:1) and 10% water daily water exchange. The initial growth of fingerlings was recorded. The experiment was settled in triplicates for 60 days and run parallel to control group provided with commercial feed and daily water exchange. Its effect was evaluated by measuring the growth of fingerlings and water parameters of each aquarium. The average % gain in weight and length of fingerlings was obtained significantly highest (28.12 ± 0.30g and 17.29 ± 0.46cm respectively) in aquaria containing pure powdered banana peels with 10% water exchange and C/N ratio was adjusted at 20: 1 (T3) than other treatments and control. Ammonia and other water parameters were also under control in T3 than other experimental and control groups. By all counts, it was concluded that the highest C/N ratio in biofloc system had the potential to increment C. idella growth rate by reducing toxicity and could be used as fish meal substitute.

Resumo A indústria avícola está entre as indústrias altamente desenvolvidas do Paquistão, atendendo a demanda de proteína da população em rápido crescimento. Por outro lado, os resíduos de aves não tratados estão causando diversos problemas de saúde e ambientais. O presente estudo foi desenhado para verificar o potencial de espécies de fungos queratinolíticos para a conversão de resíduos de penas de frango em composto biofortificado. Para tanto, três espécies de fungos foram isoladas de amostras de solo. Essas cepas foram cultivadas puramente e, em seguida, caracterizadas fenotipicamente e genotipicamente. As pesquisas do BLAST da sequência de nucleotídeos do rDNA 18S dos isolados de fungos revelaram que os dois isolados de fungos pertenciam ao gênero Aspergillus e um pertencia ao gênero Chrysosporium. A temperatura ótima para Aspergillus flavus, Aspergillus niger e Chrysosporium queenslandicum foi de 29, 26 e 25 oC, respectivamente. A. flavus apresentou degradação máxima de penas (53%), A. niger degradou resíduos de penas em até 37%, enquanto C. queenslandicum apresentou 21% de atividade queratinolítica em penas de frango em suas respectivas temperaturas ótimas. O potencial de degradação dessas espécies de fungos mostrou sua capacidade de formar composto de importância agroindustrial.

Abstract Poultry industry is amongst highly developed industries of Pakistan, fulfilling the protein demand of rapidly increasing population. On the other hand, the untreated poultry waste is causing several health and environmental problems. The current study was designed to check the potential of keratinolytic fungal species for the conversion of chicken-feather waste into biofortified compost. For the purpose, three fungal species were isolated from soil samples. These strains were pure cultured and then characterized phenotypically and genotypically. BLAST searches of 18S rDNA nucleotide sequence of the fungal isolates revealed that the two fungal isolates belonged to genus Aspergillus and one belonged to genus Chrysosporium. Optimum temperature for Aspergillus flavus, Aspergillus niger and Chrysosporium queenslandicum was 29, 26 and 25 oC, respectively. A. flavus showed maximum (53%) feather degradation, A. niger degraded feather waste up to 37%, while C. queenslandicum showed 21% keratinolytic activity on chicken feathers at their respective temperature optima. The degradation potential of these fungal species showed their ability to form compost that has agro-industrial importance.

The study aimed to test whether the ultrasonographic morphometry and characteristic traits of udders and teats could be used to identify clinical mastitis in forty-eight adult Holstein-Friesian dairy cows. The inclusion and exclusion criteria were also declared with the help of the California Mastitis Test and Somatic Cell Count. Clinically, dairy cows (n = 48) were in their third lactation in order to undergo both ultrasonographic and phenotypic morphometry. Udder parenchyma as echotexture, teat width, teat width at the rosette of Furstenberg, teat cistern width, teat wall thickness, teat canal length, and ratios of TC/TWT, TWT/TW and TC/TW, as well as supramammary lymph node size, were evaluated, whereas phenotypic morphometric traits, i.e., udder circumference, udder depth, udder length, teat length, teat circumference, teat diameter, and the shortest distance from teat ends to floor were measured. There was substantial difference between morphological parameters of the teat such as, teat width, teat width at the rosette of Furstenberg, teat wall thickness, ratio of TC/TWT, ratio of TWT/TW, ratio TC/TW, teat canal length, echogenicity variables, and phenotypic morphometric traits, except for the teat cistern width. Pearson correlation indicated a strong correlation between lymph node length and lymph node width. Clinical mastitis in cattle is related to udder and teat morphometric traits. Incorporating these characteristics into the selection and breeding programme may aid in the selection of animals for mastitis resistance. Ultrasound is an effective imaging and morphological assessment tool for the diagnosis and prognosis of clinical mastitis in dairy cows.

ABSTRACT The present study aimed to evaluate the influence of various levels of synbiotics on growth performance and intestinal morphology of fast-growing broilers during different phases. A total of 720, one-day-old straight run broilers (Ross 308) were randomly divided into 12 treatment groups according to a completely randomized design having three supplemented diets of synbiotics (a combination of probiotics and prebiotics) (0.5, 1, and 1.5%) reared at four phases [starter (1-11 days), grower (12-22 days), finisher (23-35 days), whole life (1-35 days)]. Every treatment was replicated six times with ten birds each. The parameters were evaluated in growth performance (feed intake, body weight, feed conversion ratio, and mortality) and intestinal morphology (Villus height, Crypt depth and Villus to Crypt ratio). Results of the present study revealed that growth performance, feed intake (p=0.0029), body weight (p=0.0001) and feed conversion ratio (p=0.0001) were improved with 1 percent synbiotics diet supplementation,while1.5 percent synbiotics level showed lower body weight. Crypt death (p=0.0529) has been marginally greater in the whole life. It can be inferred that a 1 % synbiotics supplemented diet has had a beneficial impact on growth and gut health throughout life.

RESUMO O objetivo do presente estudo foi avaliar a prevalência e efeitos hematológicos de Toxoplasma gondii em ovelhas e cabras no distrito Dera Ghazi Khan. Amostras de sangue (n=204) foram coletadas para incluir cabras (n=101) e ovelhas (n=103), além de idade, gênero e raça dos animais. Amostras foram coletadas aleatoriamente de 25 rebanhos de 7 conselhos sindicais: Vehova, Tibbi Qaisrani, Lakhani, Kohar, Tuman Qaisrani, Nutkani e Kot Qaisrani of Tehsil Taunsa Sharif com pelo menos 4 animais em cada rebanho. Todos os ruminantes foram divididos em três grupos baseados em idade, raça e gênero. A prevalência foi detectada usando dois kits, LAT e ELISA. A prevalência total suspeita em cabras através dos kits LAT e ELISA foi (35.64%), (32.67%) e em ovelhas foi (25.24%), (23.30%) respectivamente. O Toxoplasma gondii teve efeito significativo em cabras em grupos de idade e não significativo em todos os outros grupos de cabras e ovelhas. Toxoplasma gondii teve efeito significativo em todos os parâmetros hematológicos como hemoglobina, células totais de leucócitos, granulócitos, linfócitos, plaquetas e glóbulos vermelhos, exceto monócitos. O presente estudo conclui que toxoplasmose é prevalente entre ruminantes, e revela a possibilidade de transmissão para humanos com o uso de animais hospedeiros como fonte de proteína.

ABSTRACT The present study was carried out to evaluate the prevalence and hematological effects of Toxoplasma gondii in sheep and goat in district Dera Ghazi Khan. Blood samples (n=204) were collected comprise goats (n=101) and sheep (n=103) alongwith age, gender and breeds of animals. Samples were collected randomly from 25 flocks of 7 different union council Viz. Vehova, Tibbi Qaisrani, Lakhani, Kohar, Tuman Qaisrani, Nutkani and Kot Qaisrani of Tehsil Taunsa Sharif at least 4 animals from each flock. All ruminants divide into three groups based on age, breed and gender. The prevalence was detected through two different kits Viz. LAT and ELISA kit. The overall prevalence suspected in goats through LAT and ELISA kit was (35.64%), (32.67%) and in sheep was (25.24%), (23.30%) respectively. The Toxoplasma gondii had a significant effect on goats in age groups and non-significant all other groups of goats and sheep. Toxoplasma gondii had a significant effect on all hematological parameters like Hemoglobin, total leukocyte cells, granulocytes, lymphocytes, platelets, and red blood cells, except monocytes. In conclusion of the current study, toxoplasmosis is prevalent among ruminants, reveals the possibility of transmission to humans on the use of host animals as protein source.
