This study aimed to investigate the effect of diets with different proportions of concentrate in finishing lambs Texel on carcass characteristics and meat sheep. Twelve Texel lambs with an initial weight of 20.1 ± 2.34 kg were used. The treatments consisted of three levels of concentrate in the total ration (60,80 and 100%) and four replicates per treatment.As the values of loin eye area, finish and weight of rib and ham were higher (P <0.05) for animals receiving 80 and 100% concentrate diet compared to animals consuming 60%. Lambs receiving 100% of the diet with high grain had higher incomes, loin eye area and carcass finish, these characteristics relevant to the issue by providing animals most productive portion of edible meat and satisfactory quality to the consumer market. The levels of concentrate in the diet did not alter the qualitative parameters and sensory from lamb feedlot these characteristics that may ensure greater acceptance of the final product, so it is recommended the use of diets containing high concentrate to sheep.

Objective: To verify the effects of fish oil and soy on nitric oxide (NO) and blood pressure in patients with metabolic syndrome (MS). Subjects and methods: Sixty women with MS were investigated in a parallel randomized design study. The first group maintained their usual diet; the second group received 25 g/day of soy; the third group received 3 g/day of n-3 fatty acids, and the fourth group the same amount previously cited of n-3 fatty acids and soy. Results: Serum nitric oxide metabolites showed significant increase after 90 days in the fish oil and soy groups. Systolic pressure reduced after 45 days of treatment with fish oil, whereas diastolic pressure decreased significantly throughout the study in the soy group. Conclusions: NO increase and blood pressure reduction with fish oil or soy protein reinforce the importance of the influence of NO on blood pressure in patients with MS. Source

This study evaluated the population dynamics and ownerships of dogs and cats from the city of Jaguapitã, southern Brazil. The human to dog and cat ratios were 4.6 and 21.5, respectively. Comparatively more dogs (n=2,460) than cats (n=571) were within the households and there were significantly more male (55.8%; 679/1,217) dogs relative to females (44.2%; 538/1217). Most cats (69.2%; 180/260) did not received any antiparasitic medication, were not immunized against rabies (91.2%; 237/260) or any specific infectious disease (91.5%; 238/260). Less than half (40.8%; 106/260) of these was below oneyear- of age, but a significant number of cats was without any definite breed (81.2%; 211/260), and not spayed (93.5%; 243/260). Most dogs were of the mixed breed (69.5%; 846/1217), between one and four-years old (42.6%; 519/1217), and not spayed (96.3%; 1172/1,217). An elevated population of dogs received anthelminthic drugs (71%; 865/1,217), but most of these were not immunized against rabies (63.8% 777/1,217) or other infectious disease (58.6%; 713/1,217). Most (68.7%; 770/1,120) households were owners of a pet dog and/or cat; 54.4% (610/1,120) of these owned only dogs, 4.9% (55/1,120) were the owners of cats only, while 9.4% (105/1,120) owned pet dogs and cats. The results obtained are similar to those described in populated cities of Brazil and other countries. However, the free street access of pets associated with the reduced level of immunization against canine and feline infectious diseases coupled with the responsibility of ownership demonstrated by most residents make these animals highly susceptible to zoonotic and infectious diseases. Additionally, the free street access of unsprayed pets increases the risk of contact with other animals and the transmission of disease. Source

The aim of this research was to identify the occurrence of pathogens causing subclinical mastitis in grade B milk farms of the Jaguapitã county, state of Paraná, Brazil. California Mastitis Test (CMT) were carried out in 400 milk samples from 100 animals and 157 teats from 55 animals (55%) were positive, showed score two or higher to CMT. When these 157 positive samples to CMT were transported for bacterial culture in blood agar, 25.48% (40/157) samples showed no bacterial growth or more than two types of bacterial colonies grew, 28.03% (44/157) were Coagulase-negative staphylococci (CNS), 8.28% (13/157) were Streptococcus uberis, 7.64% (12/157) were Staphylococcus aureus, 7.64% (12/157) were Corynebacterium spp, 7.01% (11/157) were Staphylococcus intermedius, 4.46% (7/157) were Staphylococcus hyicus, 3.82% (6/157) were Bacillus spp., 2.55% (4/157) were Streptococcus dysgalacteae, Enterobacteria and Yeasts. We conclude that CNS is the most relevant subclinical mastitis causative agent. Source


The objective of this study was to determine the gamma-glutamyl transferase (GGT) levels and its relationship with diarrhea and passive transfer of immunity in Holstein calves within 24 hours and 30 days of life from Leopolis municipality, the north Parana region. Colostrum is rich in immunoglobulins and vital for immunity to newborn calves, since bovine placenta does not allow the passage of immunoglobulin to the fetus. Calves undergo various challenges that can lead to disease and death in the first month of life, including diarrhea. Diarrhea has a multifactorial etiology, and the passive immunity transferred through ingestion of colostrum is able to protect the calf against many of these etiologic agents. GGT measurements indirectly infer the amount of immunoglobulin ingested by the calf. Higher serum GGT levels (381.72 IU / L) were found at 24 hours, and a significant reduction was observed at 30 days (66.22 IU / L). When the presence or absence of diarrhea was associated with GGT levels above and below 200 IU / L, no statistical significance (P> 0.05) was observed, since 80% of animals with diarrhea had serum GGT levels higher than 200 IU / L. Under the conditions of this study, there was no relationship between the GGT concentration and the occurrence of diarrhea, and no mortality was observed despite some animals presented diarrhea. © 2016, Universidade Federal de Uberlandia.
