This study aimed to evaluate the nutritional metabolic condition of Santa Ines ewes in antepartum and postpartum period, in order to avoid toxemia. Were used 50 Santa Ines ewes management under the same condition of handling and feeding, distributed into five groups, according to the gestation period: G1-P-60 (60 days before partum), G2-P-30 (30 to 21 days before partum), G3-P0 (at partum to 4 days post partum), G4-P+30 (30 days after partum) and G5-P+60 (60 days after partum). The blood collection was conducted in the morning by venipuncture of the jugular in two vacuum tubes. The metabolites evaluated were: protein metabolism (total protein, albumin, globulin and urea), energy (glucose) and mineral (magnesium (Mg), calcium (Ca) and phosphorus (P)). To determine the differences between the means was applied the Tukey test at 5% probability. The serum concentrations of the protein metabolism (total protein, albumin and globulins), the mineral metabolism (calcium, phosphorus and magnesium) and the energy metabolism (glucose) according to the experimental phase showed significant differences (P<0.05), where the average Β-hydroxybutyrate remained within the reference values for the breed. None of gestation stages presented metabolic deficiencies in protein and energy inputs for the diet and tested management phase. The mineral calcium showed low levels at the end of gestation and early lactation.

Dermatophytosis, commonly known as ringworm, is a zoonotic disease caused by complex fungi that grow as hyphae and attach to the skin, hair and nails or claws. About 40 species of fungi of the genera Microsporum spp., Trichophyton spp. and Epidermophyton spp. are considered dermatophytes, and Microsporum canis is the genus most commonly isolated from cats. This study investigated the occurrence of dermatophytes in cats without clinical signs of skin diseases. The study involved the physical examination of 50 clinically healthy cats and the collection of samples for direct examination and fungal culture at a university veterinary hospital. The resulting data were evaluated by the chi-square association test. Of the 50 cats, 11 (22%) presented dermatophytes, with a predominance of Microsporum spp. The other 39 animals were diagnosed for non-dermatophytic fungi. Sex, breed and the presence of contactants showed no statistical difference, although there was a predominance of adult animals. The high dermatophyte infection rate confirms that cats without clinical signs can harbor these fungi, acting as asymptomatic carriers, contaminating the environment and increasing the infection rate. This study confirms that cats without clinical signs can be carriers of ringworm, which underscores the importance of the adoption of control methods even for clinically healthy animals.

The objective of this study was to evaluate the use of a vegetal source of choline as a replacement of choline chloride in the diet for broilers from one to 21 and 22 to 42 days of age. In the first experiment, we used 1500 Cobb male broilers at one day of age, distributed in a completely randomized design with ten treatments, five repetitions and 30 birds per experimental unit. In the second experiment, we used 1000 Cobb male broiler at 22 days of age, distributed in a completely randomized design with ten treatments, five repetitions and 20 birds per experimental unit. The treatments consisted of five levels of choline chloride 60% (400, 500, 600, 700 and 800 mg kg-1) and five levels of vegetal source of choline (100, 150, 200, 250 and 300 mg kg-1). There was no difference between the performance parameters of broilers in the periods of one to 21 and 22 to 42 days of age. The use of up to 100 mg kg-1 of a vegetal source of choline can replace the use of choline chloride, in the studied levels, in corn-soybean meal diets for broilers from one to 21 and 22 to 42 days of age.

Serum samples from 315 horses from Costa Rica, Central America, were examined for the presence of antibodies against Sarcocystis neurona, Neospora spp., and Toxoplasma gondii by using the surface antigen (SAG) SnSAG2 enzyme-linked immunosorbent assay (ELISA), the NhSAG1 ELISA, and the modified agglutination test, respectively. Anti-S. neurona antibodies were found in 42.2% of the horses by using the SnSAG2 ELISA. Anti-Neospora spp. antibodies were found in only 3.5% of the horses by using the NhSAG1 ELISA, and only 1 of these horses was confirmed seropositive by Western blot. Antibodies to T. gondii were found in 34.0% of the horses tested, which is higher than in previous reports from North and South America. The finding of anti-S. neurona antibodies in horses from geographical areas where Didelphis marsupialis has wide distribution suggests that D. marsupialis is a potential definitive host for this parasite and a source of infection for these horses. © American Society of Parasitologists 2011.

This study assessed the physical, chemical, and microbiological characteristics of traditionalMaiorchino cheese (Italy) made from raw ewe’s milk or from a mixture with goat’s milk. Cheese samples from the same batch were analyzed after 20 days and 6, 8, 12, 17 and 24 months of ripening. A decrease in moisture level lead to progressive total solids concentration (fat, total nitrogen, total solids and chloride) during ripening. Aw values decreased from 0.97 (day 20) to 0.85 (month 24), while pH increased from 4.99 to 5.41 (6 months) followed a by reduction until 4.85 (month 24). In samples analysed 20 days after cheesemaking, aerobic mesophilic count was 1.8•107 CFU/g, Enterobacteriaceae were 2.7•106 CFU/g, Staphylococcus spp. were 1.8•104 CFU/g, and yeasts 4.5•105 CFU/g. Sulphite reducing bacteria were not found. Lactic bacteria count at 30°C (LAB30) and 42°C (LAB42) was about 108 CFU/g (day 20); LAB30 reduced until month 8; LAB 42 reduced until month 12; both were not detectable at months 17 and 24. Cheese-making process does not consider commercial starter cultures and LAB group is heterogeneous because of its natural microflora. Yeasts were considered as typical microflora of Maiorchino. Volatile compounds were examined at 6, 12 and 24 months of ripening; 54 components were identified. Statistical analysis showed that the seasoning period of 12 months was the best forMaiorchino flavour attributes. The characterisation of Maiorchino traditional cheese may be considered as significant for this old traditional product, with the aim of obtaining the PDO certification. © F. Conte et al., 2015.

During dry seasons, equines are traditionally fed hay. However, if not prepared under favorable climatic conditions and if not properly stored, hay does not preserve its nutritional value. The aim of this research was to evaluate the chemical composition in Stylosanthes guianensis cv. Mineirão and Estilosantes Campo Grande hay varieties, used to feed equines over 225 days of storage. Treatments consisted of Stylosanthes guianensis cv. Mineirão and Estilosantes Campo Grande hay varieties, assessed at six moments of storage: 0, 45, 90, 135, 180, and 225 days. The experiment followed a completely randomized split-plot design. In the comparison between varieties, differences (P<0.05) were found for dry matter, acid detergent insoluble nitrogen, neutral detergent fiber, and lignin. The storage period altered (P<0.05) the concentrations of dry matter, calcium, and crude protein in both hay varieties. The beta-carotene content in the leguminous plants did not decline (P>0.05) over the 225 days of storage. The storage period had little impact on the nutritional quality of the assessed hays. The Stylosanthes guianensis cv. Mineirão and, mainly, Estilosantes Campo Grande hay varieties have potential to be used in equine diet.

Aim of the present work is to report data concerning the maintenance of the cold chain by retail food business operators. A total of 401 refrigerators and 105 freezers from 112 retails (big, medium, small size) were monitored for display temperatures. In addition, the surface temperature of 341 stored food products was recorded. Storage temperatures were respected in the majority of retail markets, with the exception of small retails, where cold chain was not respected. Among all food samples, yogurt was stored at temperature higher than law limits. Our findings show that retailers, in particular those from small markets, are not always familiar with cold chain maintenance. In our opinion, much more attention should be paid in keeping food at cold temperature in order to ensure food safety. © N. Costanzo et al.

The effects of adding tallow (T), poultry visceral oil (PVO), degummed soybean oil (DSO), and a mixture of T + PVO and T + DSO in different proportions in diets for broiler chickens were evaluated. The treatments were defined according to the lipid sources (LS) and their mixtures added to the diets and also according to the proportion of metabolizable energy (ME) originated from each LS (25, 50, and 75% of ME for each LS added to the feed). The experimental design was completely randomized. There were no differences (P>0.05) between treatments for body weight and food intake. Feed conversion (CA) of birds fed diets containing DSO and DSO + T (75 and 25% of ME) were lower than those chickens that were fed the diets with PVO and T (50 and 50% of ME); but showed similar results (P>0.05) to chickens of other treatments. The values found for abdominal fat and yield and composition of carcass were not affected by LS (P>0.05). It was concluded that the use of different lipid sources in diets for broiler chickens has no effect on performance and yield and carcass composition.

The objective of this study was to identify by electrophoresis the changes in the fractions of muscle proteins during the post mortem period of different genetic groups and analyse the tenderness of meat samples refrigerated for 24 hours (not aged) and aged for 7 days. Were used forty-eight samples of Longissimus muscle from bovines of 4 genetic groups: 12 Nelore; 12 crossed 1/2 Aberdeen-Angus 1/2 Nelore x Brahman; 12 Brangus; 12 crossed 1/2 Aberdeen- Angus 1/2 Nelore x Pardo submitted to superprecoce biological model. From each sample two slices was retired, one of them was not aged and the other was aged for 7 days at 2°C. In the analysis of shear force, both the nonaged samples, as those subjected to seven days of maturation did not differ on meat tenderness, but all of them showed acceptable tenderness, which can be explained by the low age at slaughter, which was provided by the fattening system that these animals were submitted. In the eletrophoretic analysis of bands of protein was noted degradation of myosin heavy chain and Troponin-T and the appearance of the 30 kDa fragment for all genetic groups after the 7 days period of aging. All the genetic groups showed good meat tenderness, regardless the ageing time.

In humans and canines, the aging process increases the risk of neurodegenerative diseases such as Alzheimer's disease and cognitive dysfunction syndrome in senior dogs. These pathological changes in different brain areas cause dementia syndromes, generating an apparent cognitive deficit characterized by behavioral changes such as alterations in memory and learning processes. The deleterious effects on quality of life in human patient affected by AD, promote the need to find similar pathologies affecting other species, making these, experimental models useful for the investigation of human suffering. Recently it has been suggested a close similarity between several of the clinical, anatomical and physiological characteristic of the Alzheimer's disease and the cognitive dysfunction syndrome senior dogs, which includes the formation and accumulation of amyloid plaques, apoptosis of cholinergic neurons with a consequent reduction of the neurotransmitter acetyl - hill, progressive type cognitive deficits and alterations in the sleep-wake cycle, among others. Thus, progress in understanding the processes involved in the pathophysiology of cognitive dysfunction syndrome senior dogs, and recognizing their similarities to those that occurred during the Alzheimer's disease, has facilitated studies aimed at understanding some aspects that have not been well detailed neurodegenrativas disease in humans. Moreover, considering the high probability of getting the cognitive dysfunction syndrome senior dogs, which is identified in several canine populations, allows for the possibility of proposing the dog changes, as an optimal model for research experimentate neurodegenerative processes associated with aging in humans.
