ABSTRACT Lutein and zeaxanthin are the major xanthophyll pigments found in corn kernels. These pigments provide the orange-red color of the broiler chicken skin and of the egg yolk. Therefore, knowing the corn xanthophyll content is important for the poultry feed producer. The objective of this study was to determine the lutein and the zeaxanthin content in corn cultivated in Colombia and in corn imported to Colombia from the United States, Argentina, and Brazil. Large differences in total lutein plus zeaxanthin content were found among the corn samples analyzed, with the highest mean level found in Colombian corn (2,758µg/100g), followed by Argentina (1,861µg/100g), United States (1,041µg/100g) and Brazil (947µg/100g). Large differences in lutein plus zeaxanthin content were also found among different corn hybrids cultivated in Colombia. Differences among geographical regions might be due to differences in UV-B radiation or in the light hours received by the crop during its growth. The differences among different corn hybrids might probably be due to genetic differences. Corn growers might be interested in cultivating hybrids higher in lutein and zeaxanthin as these pigments are very important in poultry production and human eye health.

ABSTRACT The objective of the present study was to evaluate the effect of lipopolysaccharide (LPS) administration on activation and apoptosis of primordial follicles. There was no difference in the total number of follicles as well as in the different types of follicles. Furthermore, the LPS challenge didn’t modulate the expression of genes related with ovarian reserve (HAM), oocyte survival (Survivin), activation rate (Pten, KIT, KITL1, KITL2, AKT1, SIRT1), and follicular abnormalities. Therefore, the LPS exposure with 24h interval had no effect on activation rate and primordial follicles abnormalities, and also had no effect on expression of anti-apoptotic genes and genes related with ovarian reserve, oocyte survival, activation rate, and primordial follicles abnormalities.

ABSTRACT Among the diseases that cause dyspnea in felines, primary pulmonary neoplasia is rare and tends to affect senile cats. This study reports the case of a seven teen year old FeLV infected cat who was diagnosed acinar adenocarcinoma of the lung and kidney metastasis. It presented prostration and anorexia and was hospitalized with dyspnea and pleural effusion. Chest radiography indicated increased radiopacity in the cranial portion of the right hemithorax, compatible with presence of intrathoracic mass and the cytologic analysis of pleural effusion suggested feline infectious peritonitis. The animal died two days after, and the definitive diagnosis was concluded after necropsy and histopathological examination. Pulmonary adenocarcinoma should be included with differential diagnosis of respiratory diseases in cats, especially the elderly.

There is great technological potential for the use of lactic acid bacteria (LAB) isolated from artisanal dairy products, such as cheese, and it has generated an increasing interest in the study and identification of these microorganisms, in addition to the evaluation of their potential probiotic properties. Andrade et al. (2014) and Silva et al. (2019) described in vitro probiotic potential of LAB isolated from Minas artisanal cheese produced in the Canastra and Araxá regions, respectively. However, to date, there is no research in the literature on the in vitro probiotic potential of LAB isolated from artisanal cheeses produced in the Serra Geral region, as well as their raw materials and production environment. Thus, the present study aimed to evaluate the in vitro probiotic potential of LAB isolated from those cheeses, raw milk, endogenous starter cultures and swabs from surfaces. The LAB used (Table 1) were previously isolated and identified by Caldeira (2021).

ABSTRACT Hamster breeding is becoming increasingly popular, mainly because of the simplicity of breeding, low cost, and characteristics of these animals: they are small, quiet, and do not require a large space. Because of this ease of keeping, some people choose to keep more than one animal of the same species in a single enclosure. In some cases, this sociability can lead to fights, because hamsters are extremely territorial animals, which can cause significant injuries. Knowledge of the most efficient methods for wound healing is essential in medicine for wild and exotic animals, as it allows faster clinical treatment and thus, stress reduction. The present case report refers to the therapeutic treatment of an extensive skin lesion in a golden hamster (Mesocricetus auratus) using ozonized sunflower oil. The treatment, which lasted 23 days, allowed complete healing of the lesion.

ABSTRACT Lymphoma is the most common lymphoproliferative disorder in cats. However, cutaneous lymphomas are uncommon in this species and can be classified as epitheliotropic or non-epitheliotropic. Epitheliotropic lymphomas are typically of T-cells and have tropism for epidermis and/or adnexal epithelium. Non-epitheliotropic lymphomas can be of either T-cell or B-cell and involve predominantly the dermis. The present study describes a case of multifocal cutaneous anaplastic large T-cell lymphoma. The skin nodules were multiple and variable in size, alopecic and erythematous in appearance and randomly distributed. Immunohistochemistry revealed positivity for the CD3 antigen, consistent with T-lymphocytes. This neoplasm should be remembered whenever multiple cutaneous nodules are observed in cats.

ABSTRACT Developing countries face great challenges to couple agricultural intensification and sustainable supply chain development. This paper explores the opportunities for innovation in the conservation of the locally adapted Curraleiro Pé-Duro (CPD) cattle. The CPD is a historical Brazilian breed, related to regional culture, which exhibits remarkable adaptability in tropical biomes. The research method consisted of interviewing and analyzing the discourse of CPD breeders in Tocantins, Brazil. The systematization of the data resulted in four categories and eleven subcategories, which were defined a posteriori. Our findings reveal motivational aspects, potentialities, and prospects for valuation, besides the needs and perceived challenges faced by CPD farmers. A better understanding of the current situation may guide public policies, encourage stakeholders, benefit farmers, and lead to sustainable agri-food initiatives. The empirical contributions of our diagnosis are discussed, and we show how they bring forward and provide valuable lessons to prospect innovations in the conservation of CPD cattle. These findings may support scholars and people who are also interested in accessing and supporting the conservation of indigenous livestock. In general, the study supports the definition of strategies, planning, and investments for the value chain, including the participation of upstream and downstream segments of the farms.
发展中国家如何将农业集约化与可持续供应链发展结合起来，面临着巨大的挑战。本文探讨了在保护当地适应的Curraleiro p - duro (CPD)牛方面的创新机会。CPD是一个历史悠久的巴西品种，与区域文化有关，在热带生物群落中表现出卓越的适应性。研究方法包括对巴西托坎廷斯地区CPD育种者的访谈和话语分析。数据的系统化产生了四个类别和十一个子类别，这是后验定义的。我们的研究结果揭示了CPD农民的需求和面临的挑战之外，价值评估的动机方面、潜力和前景。更好地了解当前形势可以指导公共政策，鼓励利益相关者，使农民受益，并导致可持续农业食品倡议。讨论了我们诊断的经验贡献，并展示了它们如何为CPD牛保护的前景创新提出并提供宝贵的经验教训。这些发现可能会支持那些对获取和支持土著牲畜保护也感兴趣的学者和人们。总体而言，该研究支持价值链战略、规划和投资的定义，包括农场上游和下游部分的参与。

ABSTRACT The aim of study was to determine the relationship between metabolic parameters, body weight and body growth of piglets at birth and weaning. The experiment included 80 piglets obtained from F1 generation sows. Body weight was measured at birth (BW0), 24h (BW1) after birth and on day 25 (at weaning, BW2). Blood sampling was performed at the beginning of life (3rd day after birth) and at weaning (21st day after birth). BW0 and BW1 positively correlated with cholesterol and negatively with urea values at the beginning of life and RBC values at weaning. BW2 positively correlates with albumin and cortisol values at the beginning of life, total proteins, and globulins at weaning, and negatively correlates with erythrocyte values at weaning. Piglet growth from birth to weaning (BWG2-0) correlates positively with total proteins, albumin, and cortisol at the beginning of life and total proteins at weaning. ROC analysis shows that MCHC, TPROT, GLOB, CHOL and AST at the beginning of life can distinguish fast-growing from slow-growing piglets from birth to weaning period. The use of blood parameters enables early recognition of growth rate in piglets, which can help to optimize all further steps to achieve the best possible growth.

ABSTRACT A case of infection with Dirofilaria immitis in a cat is reported here with clinical signs of apathy, anorexia, dyspnea, polypnea, slight dehydration and pale mucus membranes. The radiographic examination showed cardiomegaly, lobar arteries dilation of the cranial lobes and tortuosity, enlargement of the caudal lobar arteries. In the right lobe of the lung parenchyma, interstitial pulmonary opacification tending to alveolar opacification was seen. The clinical signs, the movements, and the morphology of the microfilariae in the direct examination of fresh blood, peripheral blood smear and Knott’s modified test supported the diagnosis. We alert to the need for clinicians to consider feline heartworm diseases as a differential diagnosis in endemic areas when cats show respiratory signs.
