This study contributes new insight into the comparative nutrient profiles of neo-tropical species “agouti (Dasyprocta leporina); nine-banded armadillo (Dasypus novemcinctus): opossum (Didelphis marsupialis) and lowland paca (Cuniculus paca)” compared to domestic species “cattle, veal (Bos taurus); sheep (Ovis aries); goat (Capra aegagrus hircus) and pigs (Sus scrofa domesticus)”. The research aimed to assess the chemical and mineral content present in the livers of these species as there was a growing interest for more sustainable and healthier meat sources. Analysis revealed significant differences in the composition of crude fat, iron, calcium, potassium, sodium, and phosphorus between the neo-tropical and domestic species. Neo-tropical species exhibited higher levels of crude fat, iron, calcium, and potassium, while domestic species showed higher levels of sodium and phosphorus. The results highlighted the potential nutritional advantages of incorporating underutilized neo-tropical offal into human diets, particularly in regions facing micro-nutrient deficiencies, particularly in iron, calcium and potassium.

The present study evaluated the effect of six phytoadditives (PFA) on the quail egg quality and performance of layer quails. 360 birds (6 weeks old) were randomly distributed into eight groups [n = 45 (15-birds/replica)] viz. negative control (NC, maize-soya-based diet), positive control [PC, herbal growth promoter (Reproforte plus™) was supplemented at 0.05 % (w/w)] and T1, T2, T3, T4, T5, and T6 groups supplemented with 1.0 % PFA i.e. turmeric, garlic, fenugreek, cumin, Aloe vera and oregano powders, respectively. The PFAs were fed for 22 weeks. The PFA inclusion improved (P < 0.05) hen-day egg production and feed-conversion ratio during the first three months of treatment without any effect on feed intake. The PFA-supplementation enhanced the yolk colour (b* and a* values) and the eggs’ antioxidant activity compared to NC. While serum protein profile and enzymes showed no change (P > 0.05), the serum cholesterol (mg/dl) was significantly reduced in the T2 (garlic) and T3 (fenugreek) groups and LDL was reduced significantly in the T3 group. The PFA supplementation enhanced the overall acceptability of the eggs. The return on investment (%) was higher for the T1 (turmeric), T3 (fenugreek) and T5 (A. vera) groups. It may be concluded that PFA supplementation is beneficial economically and enhances egg quality.

Influenza is a major infectious disease challenge affecting animal and human health globally, and wild birds are historically the primary reservoirs of all the known Influenza A virus subtypes. Here, we detected the Highly Pathogenic Avian Influenza (HPAI) virus in exotic and aquatic birds in three different locations in Nigeria. On the 8th of February 2021, exotic birds: Yellow Golden Pheasant (Chrysolophus pictus), Sultan chicken (Gallus gallus domesticus), Lakenvelder chicken (Gallus gallus domesticus), and Common pheasant (Phasianus calchicus), imported from Libya and transported across the Niger Republic border to Nigeria, were presented to the National Veterinary Research Institute, Vom, for screening. Also, a family in Lagos State bought some exotic aquatic birds from a live bird market in Sokoto State, Nigeria, where sudden death was recorded with the birds showing few clinical signs. Similarly, the sudden death of some aquatic birds was reported in Mandela Parks and Gardens in Asaba, Delta State, few weeks after some captured wild birds were introduced to the Park and Gardens. Oropharyngeal, cloacal, and tissue samples were all collected from the reported cases. Total viral nucleic acid was extracted and screened for Influenza A viruses using real-time RT-PCR. The HPAI viruses H5N1 and H5N8 were detected in the imported aquatic (geese and ducks) and exotic (yellow golden pheasant) birds. The samples tested negative for low-pathogenic Avian Influenza Virus (H9N2) as well as other avian viruses, viz., Avian avulavirus-1 (Newcastle disease Virus) and infectious bronchitis virus. This highlights the role of these birds in the local transmission and spread of the HPAI virus to domestic poultry. The findings call for proper biosecurity and quarantine measures for exotic and wild birds to reduce the potential risk.

Background
Exocrine pancreatic carcinoma has been rarely reported in the Mustelidae family, with occasional descriptions in ferrets (Mustela putorius furo) and other species. Although the European mink (Mustela lutreola) belongs to this family, exocrine pancreatic carcinoma has never been documented in this species. The aim of this report is to describe a case of exocrine pancreatic carcinoma with abdominal carcinomatosis in a European mink.
Case: A six-year-old, 0.79 kg, non-neutered male European mink from a French zoological institution presented an abdominal distension and difficulty defecating for several days.
Diagnostic Examinations: Physical examination and ultrasonography revealed a perirenal effusion adjacent to a 4 cm abdominal mass. Fine-needle aspiration of the effusion yielded haemorrhagic fluid. Biochemical analysis indicated renal impairment, while haematological evaluation revealed non-regenerative anaemia and lymphopenia. The animal died a few minutes after anaesthesia induction. Post-mortem examination identified a haemorrhagic abdominal effusion and a 4 cm neoplastic mass located near the mesenteric lymph node and pancreas. The tumour had infiltrated the left kidney and liver. Histopathological analysis confirmed the diagnosis of exocrine pancreatic carcinoma with mesenteric carcinomatosis affecting the liver and kidney.
Clinical Relevance: To the best of our knowledge, this condition has not been previously reported in the European mink.

Bisphenol A (BPA), a polycarbonate monomer commonly found in plastics, is an endocrine disruptor compound (EDC) that mimics the activity of steroid hormones. This study aimed to examine BPA’s effects on Mongolian gerbils’ ovary. Pregnant females (n = 5) were assigned to four groups and exposed by gavage to BPA at two doses (↓BPA, 50 µg/kg; ↑BPA, 5000 µg/kg), an oil vehicle (OC) or remained untreated (IC) from the eighth gestational day until weaning. One female from each offspring was euthanized at six months of age, and had their ovaries processed histologically. Cytochemistry was performed: HE for quantification and classification of follicles; Gomori’s Trichrome for collagen fibers; Resorcin-Fuchsin, for elastic fibers; and reticulin, for reticular fibers. Immunohistochemistry was used to analyze estrogen receptor alpha (ERα) and beta (ERβ), and the proliferative index. Results showed no significant differences in primary or secondary follicle counts among the IC, OC, ↓BPA, and ↑BPA groups. Antral follicles showed a higher incidence in the ↑BPA (6,4 ± 1,0) compared to the IC (2,7 ± 0,4) and OC (2,8 ± 0,4) groups. Collagen fiber density was significantly higher in the ↑BPA group (38,0 ± 7,5) compared to the OC group (20,7 ± 6,2). Similarly, elastic fibers were increased in the ↑BPA group (7,4 ± 0,9) relative to ↓BPA (1,8 ± 0,4), OC (2,3 ± 0,5) and IC (2,6 ± 0,9), as were reticular fibers (↑BPA: 31,5 ± 1,8; ↓BPA: 17,8 ± 2,6; OC: 14,1 ± 2,3; IC: 12,9 ± 1,2). Additionaly, BPA-exposed groups exhibited fewer interstitial glands, suggesting a reduction in steroidogenic potential. The tissue response to estrogens was elevated among animals from the ↑BPA group within activated follicles, regarding receptors alpha and beta. Higher proliferation indexes were present within activated follicles and interstitial steroidogenic glands from the ↑BPA group as well. Therefore, dysregulation of estrogenic response and establishment of fibrosis observed in our results indicate deleterious effects on the ovary’s morphophysiology, potentially leading to a pathological environment. This attests that perinatal exposure to BPA affects the offspring even in a long-term manner.

Intestinal diverticula are a well-documented phenomenon in humans, but their occurrence and characteristics in domestic rabbits remain underexplored. While pseudodiverticula have been reported in rabbit species, true diverticula—with all layers from mucosa to serosa—are yet to be described. This case report presents a 3-yearold neutered female rabbit with an unusual presentation of true diverticula in the jejunum, leading to diverticulitis and partial intestinal obstruction.

Background
Encrusting cystitis diagnosis and medical management in domestic ferrets (Mustela putorius furo) has never been documented.
Case description
A client-owned, 6.5-year-old, neutered, male domestic ferret was presented for lethargy, abdominal pain, straining to urinate for 12 days, and red, purulent urine. On physical examination, the ferret was quiet, alert, and responsive, had a distended and inexpressible bladder, large and firm kidneys, and was displaying signs of severe pain including vocalization on abdominal palpation and when attempting to urinate. Sonographic evaluation showed an irregular, layered, hyperechoic mass lesion present in the lumen of the urinary bladder with extensions of the layered luminal material into the urethra, and severely dilated renal pelves and ureters. These severe, urinary bladder changes were consistent with pseudomembranous, encrusting cystitis. Following a discussion with the owner about options for humane euthanasia versus exploratory surgery, euthanasia was elected. The remains were taken home with the owner and a necropsy was not performed.
Conclusion and case relevance
To the author’s knowledge, this paper reports the first known case of suspected encrusting cystitis in a domestic ferret including radiologic and ultrasonographic findings.

Exposure to 17α-ethinylestradiol (EE2), a synthetic estrogen, during the developmental period has been found to induce pathological changes in the morphology and function of the gerbil ovary. However, the extract of pequi oil from the fruit Caryocar brasiliense Cambess exhibits anti-inflammatory, antifungal, and anticarcinogenic properties. This study aimed to assess the effects of prenatal exposure to pequi oil and EE2 on ovarian folliculogenesis in gerbils. Pregnant female gerbils were divided into five groups: Control; EE2, which received EE2 (15 µg/kg/day) during gestation; Vehicle (Ve), which received only the vehicle; EE2/Pe, which received EE2 and pequi oil (300 mg/kg); and Pe, which received only pequi oil. Female offspring were euthanized at 12 months of age, and their ovaries underwent histological processing. Body and ovarian weights remained unchanged in this study. However, the experimental groups showed a decrease in the number of primordial follicles compared to the control group. Notably, the EE2/Pe group exhibited an increase in the number of secondary follicles compared to the other groups. Statistical analysis revealed significant differences in the number of atretic follicles among the groups, with both the EE2/Pe and Pe groups exhibiting the highest numbers of atretic follicles. In summary, the detrimental effects on ovarian morphophysiology induced by EE2 exposure during pregnancy were evidenced by a global reduction in ovarian follicles and an increase in the number of atretic follicles. Consequently, the indiscriminate use of endocrine disruptors, particularly during pregnancy, can lead to significant alterations in the ovarian reserve.

Pregnant female gerbils were divided into five groups: <em>Control</em>; <em>EE<sub>2</sub></em>, which received <em>EE<sub>2</sub></em> (15 µg/kg/day) during gestation; Vehicle (<em>Ve</em>), which received only the vehicle; <em>EE<sub>2</sub>/Pe</em>, which received EE2 and pequi oil (300 mg/kg); and <em>Pe</em>, which received only pequi oil. Female offspring were euthanized at 12 months of age, and their ovaries underwent histological processing. Body and ovarian weights remained unchanged in this study. However, the experimental groups showed a decrease in the number of primordial follicles compared to the control group. Notably, the EE2/Pe group exhibited an increase in the number of secondary follicles compared to the other groups. Statistical analysis revealed significant differences in the number of atretic follicles among the groups, with both the <em>EE<sub>2</sub>/Pe</em> and <em>Pe</em> groups exhibiting the highest numbers of atretic follicles. In summary, the detrimental effects on ovarian morphophysiology induced by EE2 exposure during pregnancy were evidenced by a global reduction in ovarian follicles and an increase in the number of atretic follicles. Consequently, the indiscriminate use of endocrine disruptors, particularly during pregnancy, can lead to significant alterations in the ovarian reserve.</p></div>","PeriodicalId":100464,"journal":{"name":"Emerging Animal Species","volume":"11 ","pages":"Article 100049"},"PeriodicalIF":0.0,"publicationDate":"2024-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S277281372400009X/pdfft?md5=089da21a5180870ec745a8ece5747a30&pid=1-s2.0-S277281372400009X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142162170","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study was carried out to describe the occurrence and pathological findings in infections with Eimeria spp. in budgerigars. Postmortem examination was conducted on the carcasses of 32 Budgerigars received from various pet shops, pet bird breeders and pet bird owners of Puducherry. The budgerigars were of either sex and their age ranged from 1 to 5 years. The reported clinical signs were anorexia, lethargy, loss of body weight and diarrhoea. Coccidiosis was diagnosed in 46.87 % (15/32) of the cases. Gross features were localized in the small intestine and included serosal congestion, catarrhal, haemorrhagic and necrotic enteritis. The intestinal scraping revealed oocysts of Eimeria spp. Histological examination of various portions of the small intestines revealed catarrhal, haemorrhagic or necrotising enteritis and the developmental stages of Eimeria spp. in the intestinal and the crypt epithelium and also in the lumen of the intestine. Other changes were crypt cell proliferation and mononuclear cell infiltration.
