The quality of raw milk depends on initial microbial contamination and conditions of storage until industry processing. Considering the influence of time and storage temperature on raw milk microbiota, the objective of this work was to quantify and monitor the multiplication of these groups under different conditions. For this purpose, 41 samples of raw milk were collected immediately after milking, stored in the following storage conditions: 25 °C/2 h; 35 °C/2 h; 7 °C/24 h; 7 °C/48 h and 7 °C/60 h and analyses of aerobic mesophilic, psychrotrophic and proteolytic psychrotrophic microorganisms. The milk samples analyzed in the study had an initial mean count of mesophilic aerobes of 5.38 Log CFU/mL at Time Zero. The milk stored at 25 °C/2 h and 35 °C/2 h kept the mesophilic aerobic counts within the limits established by the legislation (5.48 Log CFU/mL), with an increase in counts of psychrotrophic and proteolytic microorganisms. When stored at 7 °C/24 h and 7 °C/48 h, the count of mesophiles exceeded the established parameters. A significant increase in the count of proteolytic psychrotrophs and psychrotrophs was also observed during storage at 7 °C from 24 h. The results of this study indicate that the temperature of 7 °C is not suitable for the milk conservation, since it was not able to control the microbial multiplication. Thus, the results contribute to the change in milk storage temperature proposed by the new Brazilian legislation.

Urinary bladder rupture is rarely reported in adult horses and is usually associated with parturition, history of trauma or urethral obstruction. This paper reports two cases in mares free of these predisposing factors, diagnosed through clinical manifestations, abdominal ultrasound and abdominocentesis, corrected by cystorrhaphy through laparotomy. While recovery was satisfactory in one case, the other case had complications in celiorraphy such as development of incisional hernia, small colon eventration and intestinal adherences, opting by the euthanasia of the animal. These reports are important because of the rarity with which they occur in adult mares. The different prognoses may be related to the severity of each case, according to the location and extension of the wound, which directly or indirectly influence the technique and recovery of the animals.

An Andean fox was transferred to the Wildlife Hospital of the Universidad San Francisco de Quito for evaluation of injuries caused by a run over. Clinical signs of hypovolemic shock were detected. Radiographies showed multiple pelvic fractures and free fluid in retroperitoneal cavity. The presumptive diagnosis was hemorrhagic shock caused by blood loss secondary to a pelvis fracture. An emergency xenotransfusion using blood from a domestic dog was performed without acute transfusion reactions observed. This is the first report of successful xenotransfusion between a domestic dog and an Andean fox presenting a procedure that could be applied in emergency situations.

In recent years, the relationship between humans and companion animals has tightened considerably and resulted in the expansion of the range of pet food industry products available in the market. In this context, snacks have gained greater popularity as pet owners seek to please their animals by providing such foods. Due to the growing importance of the snack segment, a need exists for accurate information on the nutritional composition of these products, such as fat concentration. No studies were found that evaluated the effectiveness of different methods applied for determining the content of this nutrient in dog snacks. In addition, too much mineral content can pose health risks. Thus, the objective of this study was to compare three methodologies for determining fat in pet snack products. The moisture, calcium and phosphorus content of each was also determined to compare the obtained results with each value stated on their product labels. Fat determination methods evaluated were ether extract (EE), ether extract after acid hydrolysis (EEHA), and fat content obtained from Ankom XT15 analyzer (ANKOM). Twenty-four snacks produced by 17 companies were evaluated. The results of the three methodologies were compared using the Tukey test. The comparison between the results of the laboratory analysis and the values stated on the labels was performed using descriptive statistics. There was no difference between the three methods evaluated (p = 0.34) regarding fat content. Regarding the nutritional compliance of the labels, 25% (n = 6) of the snacks presented higher moisture content than the declared amount, 50% (n = 12) presented lower fat content, 25% (n = 6) lower phosphorus content and, in 50% (n = 12), the calcium content was not within the minimum and maximum range stated on the label. Therefore, due to the absence of difference between the results, any of the three fat determination methodologies could be used. Regarding compliance of labels for calcium, phosphorus and fat content, greater control over the nutritional composition of these foods is required since most pet owners tend to supply large quantities of snacks to dogs, leading to excessive daily energy intake.

In nature, cockatiel (Nymphicus hollandicus) feed consists of a huge variety of seeds, fruits, flowers, leaves, and insects. In captivity, their feed is generally poor, as many breeders offer only a mixture of seeds as food, leading to nutrient deficiency and even obesity. This paper presents a study on cockatiel feeding behavior in artificial environments at different stages of development (growth, maintenance, and reproduction), to evaluate their preference from the offer of six different food types (sunflower seed, oats, millet, rice, ration, and a cornmeal based feed or farinhada), and an analysis of their preferences for locations in the cage. No significant differences were observed about the final weight of the birds during the stages of development. Consumption of millet seeds was significantly higher in the growth stage, but at this stage, the birds showed a preference for oats. On the other hand, at the reproduction and maintenance stages, they showed a preference for sunflower seeds. The birds in the reproduction stage were the ones that visited the nest, and the nest grid, the most. Among all the cage locations, all birds showed a preference for the perches.

Tilapia skin is being already use in humans and wild animals present burning wounds and showed a great result. The objective is to evaluate if tilapia skin used as an occlusive curative improves equine wound healing in two horses present chronic wound. Both animals are males, adults, both of breed Mangalarga Marchador South America. Every seven days wound we measured, photographed, biopsied for histopathological analysis, cleaned and tilapia curative was changed. Image J software was used to measure wound area. Tilapia skin as an occlusive biological factor seemed to improve healing process, wounds present an area reduction and clinical improvement during 35 days treatment, even though is still waiting for complete wound healing. In equine tilapia skin curative seemed to speed up healing process and allowed reduced curative change from every two days to once a week. This implies in decrease animal´s stress, less pain and treatment cost reduction since we used less bandage amount. Beside that tilapia skin industrial waste. Furthermore, it allowed avoid using antibiotics, which reduces environment pollution and there´s no antibiotic resistance issues.

We characterized the network of cattle movements in Mato Grosso, Brazil—a state responsible for a significant amount of Brazilian beef exports. In this analysis, we were particularly interested in the importance of slaughterhouses in the network of cattle movements, in the characteristics of the trade for different purposes (especially for reproduction, fattening, and slaughter), and about the importance of the main traders. We found that the median distance of all movements was 79.0 km, with an interquartile range between 37.2 and 163.2 km, which suggests a relatively short-range trade pattern; roughly 20% of the premises purchasing more animals were responsible for 95% of the animals purchased and 20% of the premises selling more animals were responsible for 86% of the animals sold, indicating the importance of the cattle trade hubs. Fitting the degree distribution using a power-law distribution, we obtained a scaling parameter of 2.59, indicating that the cattle movement network of Mato Grosso is less dense than other observed cattle movement networks. The networks for fattening, reproduction, and slaughtering only comprised 73%, 56%, and 25% of all nodes and 52%, 30%, and 17% of all edges, respectively; and slaughterhouses had the highest in-degrees and total degrees, followed by markets and farms, playing the role of main cattle trade hubs. Therefore, slaughterhouses are potentially useful as surveillance points to detect cases, and controlling important trader premises may optimize the use of resources for controlling diseases.

Considering the importance of leptospirosis in both equine husbandry and public health, as well as the relevance of knowledge of current serogroup and the small number of studies addressing this disease in equines in Northeastern Brazil, the present study performed a serological survey of Leptospira spp. in a serum bank of 1,267 equines originating from 177 municipalities, located in four states in Northeastern Brazil: Ceará, Rio Grande do Norte, Paraíba and Pernambuco. The microscopic agglutination test (MAT) was used for diagnosis of leptospirosis using 24 serovars as antigens. The frequency of reagent equines was 29.7% (376/1,267), and 68.9% (122/177) of municipalities had at least one positive reaction. The serogroups reagent were Australis (37.2%), Icterohaemorrhagiae (29.3%), Tarassovi (9.6%), Sejroe (5.8%), Pomona (5.3%), Grippotyphosa (4.5%), Pyrogenes (2.4%), Bataviae (1.9%), Ballum and Hebdomadis (1.3%), Mini (0.5%), Celledoni, Shermani, and Javanica (0.3% each). There were significant statistical differences regarding sex and age, with a higher frequency in females (P= 0.014), and in animals ≥ 6 years (P=0.001). We concluded that seropositivity to Leptospira spp. is high in equines in Northeastern Brazil, with a predominance of serologic reactions to the Australis serogroup in the border areas between the states, and the Icterohaemorrhagiae serogroup in coastal areas or their vicinity. The high degree of seropositivity found points to the need to implement prophylactic strategies, both intraspecies infection prophylaxis and rodent control. We also recommended avoiding animal crowding and separating animals according to sex and age group during handling.
