ABSTRACT Salmonella Gallinarum is capable of causing high mortality in birds of the order Galliformes. This study aimed to relate the presence of clinical signs with the recovery of Salmonella Gallinarum from organs and c loacal swabs of Japanese quails (Coturnix coturnix) experimentally infected. A total of 70 female quails were housed in a pair per cage and divided in two groups (IG: quails inoculated with 1.5x106 CFU of Salmonella Gallinarum Nalr/mL and CG: control group). After the inoculation, birds were evaluated three times a day to verify the presence of clinical signs. Birds that presented ruffled feathers, eyes closed and remained quiet in the cage were removed for euthanasia, as well as the same number of birds from the inoculated groups that presented no clinical signs and from the control group. Cloacal swabbing was performed following euthanasia for the sampling of liver, spleen, caeca, ovarian follicles and lung for microbiological procedure. Quails with clinical signs and quails found dead presented positivity of 100%. While inoculated quails with no clinical signs presented a lower positivity (38.5%). Therefore, quails with septicemia caused by SG present clinical signs of the disease and the pathogen can be isolated and quantified in the organs.

Fowl typhoid a high-impact disease in the poultry industry, this study aims to verify the clinical signs of the disease in experimentally inoculated with quail Salmonella Gallinarum 54 Japanese female quails were distributed into two groups. The inoculated group (GI) SG (32 quail) and control group (CG) (16 birds). A total of six birds were euthanized before the start of the experiment, organs samples (liver, spleen, ovarian follicles, cecum and lung) were collected for the microbiological analysis. The birds of the GI group received 0,7mL of inoculum (1.5x106 CFU/mL) and birds of the CG group received 0,7 mL of saline solution. Thereafter, the quails were observed for ten consecutive days in three daily periods (8:00, 11:00 e 14:00) in order to observe clinical signs of disease. After four days of inoculation was verified prostration, apathy, ruffled feathers, diarrhea, bird's stay in the corner of the cage with closed eyes and reluctance to move (13/32). Some macroscopic changes were observed in euthanized birds with clinical signs like splenomegaly and splenic necrosis in 84,6% (11/13) and 23,0% (3/13) respectively, hepatomegaly and liver necrosis in 15,4% (2/13) e 23% (3/13) respectively, and atrophy and hemorrhage of ovarian follicles in 15,4% (2/13) and 7,7% (1/13) respectively. the birds that died was observed only hepatosplenomegaly. So we can conclude experimentally inoculated with Salmonella Gallinarum quail have the typical clinical signs of fowl typhoid observed in others birds of Galliforme order.

Background: Coccidiosis is one of the most dangerous diseases infecting Japanese quails. This work was conducted to study the efficacy of immunization of Japanese quail against the challenge with different Eimeria species causing coccidiosis and to optimize the dose of live sporulated oocysts that give immunity without adverse effects. Methods: Dropping samples were collected from different Japanese quail pens of the Central Poultry Development Organization, Bhubaneswar, Odisha, India. Isolation, identification, single oocyst isolation and propagation were done for each species. On the 2nd day of age, Japanese quails were divided into 10 groups and orally inoculated with low doses, 100 and 1000 live sporulated oocysts, of each isolated Eimeria species separately. Four weeks post-immunization, the quails were challenged with a high dose of the respective species. Immunization efficacy was assessed regarding clinical signs, mortality rate, weight gain, feed consumption, feed conversion ratio, oocysts output, lesion scores and hematological parameters. Result: All collected samples were Eimeria positive. Three Eimeria species were isolated and identified as E. bateri, E. uzura and E. tsunodai. Experimental results revealed that the immunized quails, either by 100 or 1000 oocysts of any isolated species, showed better results compared to the challenged, non-immunized controls. The 100-oocysts dose gave better results than those of 1000-oocysts dose without significant differences. These results indicated the effectiveness of immunization as an important tool in the management of Japanese quail coccidiosis.

The present study aimed to evaluate the effect of dietary Moringa oleifera (M. oleifera) leaves and/or seed powder on laying Japanese quail performance in terms of egg production, egg quality, blood serum characteristics, and reproduction. In total, 168 Japanese quails (120 hens and 48 males) at eight weeks of age in laying period were randomly distributed to four treatment groups, with six replicates per group and seven birds (five hens and two males) per replicate. The first group (G1) served as a control group, while G2, G3 and G4 groups were supplemented with M. oleifera leaves (ML) and M. oleifera seeds (MS) and their combination ((1 g/kg ML; 1 g/kg MS; and 1 ML g/kg + 1 MS g/kg (MSL), respectively). From the results, feed consumption, feed conversion ratio, egg weight, fertility and hatchability from fertile eggs, egg and yolk index, and Haugh unit were not affected by dietary treatments. However, egg production, egg mass, eggshell thickness, and hatchability were significantly increased and blood aspartate transaminase (AST) and urea decreased in the MS treatment. Both triglycerides and total cholesterol were reduced (p < 0.05) in all treatments with ML, MS, and MSL, with no significant differences in alanine aminotransferase (ALT), albumin, total protein, globulin, and A/G ratio among dietary treatment. Our results clearly indicated that the inclusion of M. oleifera seeds in Japanese quail diet significantly increased egg production and improved hatchability, along with some egg quality parameters, and also lowered some blood biochemical components.

Dietary Treatments

One hundred and eighty (180) unsexed twenty-one day-old growing Japanese quails (Coturnix coturnix japonica) were fed for 28 days with diets in which maize was replaced with cassava grit at 0, 25 and 50% with or without β-glucanase supplementation. The birds were randomly grouped into six treatments in three replicates of ten birds per replicate. Diet 1 was the control without cassava grit while diets 2 and 3 had 25 and 50% of their maize contents replaced with cassava grit respectively. Diets 4, 5 and 6 were the same as diets 1, 2 and 3 respectively but for the inclusion of β-glucanase at 100mg/kg. Feed and water were supplied ad libitum throughout the period of study. Feed intake (590.98g), weight gain (93.77g) and FCR (6.35) were significantly (p<0.05) affected by the dietary treatments. 6 Among the haematological parameters monitored RBC (4.46x10 /UI) and WBC 3 (26.52x10 /UI) were significantly (p<0.05) affected by dietary treatments. Thiocynate (2.57 mg/ml), AST (290.6 U.I/L) and ALT (33.6 U.I/L) were also significantly (p<0.05) influenced by the experimental diets. Replacement of 25 or 50% maize with cassava grit in diets of the Japanese quail diets did not have negative effect on haematology and serum biochemistry of the birds. There were however significant differences (p< 0.05) affected by the treatments while caeca length and the lungs weight were statistically similar across the treatments. Replacement of maize with cassava grit at 25 and 50% in Japanese quail diets had no negative effect on haematology, serum biochemistry and carcass characteristics of the birds.

This study aimed at evaluating the use of scanning electron microscopy in the study of the post-vaccinal respiratory reaction of the tracheal epithelium of quails (Coturnix coturnix japonica) immunized against Newcastle disease. A number of 36 quails were distributed into four groups: T1 <FONT FACE=Symbol>¾</FONT> control birds (non-vaccinated); T2 <FONT FACE=Symbol>¾</FONT> birds vaccinated with Ulster 2C strain; t3 <FONT FACE=Symbol>¾</FONT> birds vaccinated with B1 strain; t4 <FONT FACE=Symbol>¾</FONT> birds vaccinated with LaSota strain. Regardless the experimental group, birds did not show detectable clinical signs of post-vaccinal respiratory reaction. However, the analysis of tracheal fragments by scanning electron microscopy showed that birds vaccinated with B1 and LaSota strains developed epithelial sloughing of the trachea, whereas those vaccinated Ulster 2C strain did not develop this change, demonstrating intact tracheal epithelium, similar to the control group.

The aim of this study was to determine the pathological effects of formalin on female quails. Seventy-five 1-day-old female Japanese quails (Coturnix coturnix japonina) were divided into five equal groups (A–the eighth week. No clinical signs were observed in quails fed 2.5 mL formalin/kg feed. Depression, dullness and anorexia were prominent in quails fed 20 mL formalin/kg feed. Feed intake, body weight, egg production and egg weight together with absolute and relative weight of organs, erythrocyte and leukocyte counts, hemoglobin concentration and hematocrit were decreased at higher doses, i.e., 10 and 20 mL formalin/kg feed. Total serum proteins and globulin significantly increased (P B / 0.05) in all formalin fed quails compared to control birds. No gross lesions were observed in the 2.5 mL formalin/kg fed group. At higher doses (10 and 20 mL formalin/kg feed) hemorrhages on the thigh muscles, decreased weight and reduction in area and folds of different segments of oviduct were recorded. Reduced size of liver, heart and kidneys was recorded in quails fed 20 mL formalin/kg feed compared to controls and other birds. The histopathological changes in oviduct consisted of degeneration of mucosal glands characterized by vacuolation of nuclei of cells. It was concluded from the study that formalin feeding to female quails at 2.5 mL/kg feed is without harmful effects, however, higher doses are not without health risks.

ABSTRACT Coturniculture has increased significantly in the last decades. There are several pathogens that can affect these birds. Among the diseases, fowl typhoid stands out as a disease with a potentially great impact to the poultry industry. The objective of this the study was to evaluate the effect of doses and administration routes of live 9R vaccine on protection of Japanese quails against experimental infection with Salmonella Gallinarum (SG). Two hundred and fifty birds were used, divided into five groups: G1, oral vaccination with one dose; G2, oral vaccination with 2 doses; G3, subcutaneous vaccination with one dose; G4, subcutaneous vaccination with two doses and G5 not vaccinated. All birds from all five groups were challenged with SG at an age of 45 days. SG was quantified in the periods of one, four, seven and twelve days after the challenge. The presence of clinical signs and macroscopic lesions of the disease were observed. The groups vaccinated by subcutaneous route had a higher egg production and lower mortality rate. Birds receiving a dose of the vaccine by subcutaneous route also showed lower amount of SG in the liver and spleen seven days after the challenge.
