title: Usage of probiotic in country-type broiler's chicken diet and its effects over the carcass yield, morphology and the gastrointestinal pH

description: SUMMARY This study had as an objective to evaluate the carcass yield, morphology and intestinal pH of male country hick broilers raised on Tifton-85 pickets, fed with commercial probiotic supplemented ration. A total of 210 one-day-old males broiler's chicken from the Peeled Neck lineage were raised in experimental boxes on a conventional shed until 30 days of age, and from 30 to 90 days of age they had access to Tifton-85 pickets (Cynodonspp.). The carcass yield variables evaluated were live weight at 90 days, carcass weight (with foot, neck and head), carcass weight (without foot, neck and head), thigh, chest, wings, edible viscera, inedible viscera, abdominal fat, pH, length and weight of the gastrointestinal tract compartments (gut, duodenum, jejunum, ileus, proventriculus, gizzard, and cecum). All data went through analysis of variance, and the means of the treatments were compared by the F test with 5% of probability. Variables of carcass yield, primary and secondary cuts, length, weight and pH of gastrointestinal tract compartments were not influenced (P&gt; 0.05) by treatments with and without probiotic addition. Inclusion of 300 g / ton of the probiotic Bacillus subtilis DSM 15,544 in broiler's chicken from the Peeled Neck lineage had no influence over the carcass yield, pH and morphology of the gastrointestinal compartments of the birds in the period and levels in the present experiment. The sanitary challenge was not enough to demonstrate the effectiveness of probiotic action.

title: Structural characteristics and chemical composition of andropogon grass pasture managed under different defoliation intensities and rest periods

description: SUMMARY This study aimed to evaluate the agronomic, structural traits and chemical composition of andropogon grass subjected to different defoliation intensities and rest periods. Two defoliation intensities (15 and 30 cm) and four rest periods (25; 35, 45 and 55 days) were evaluated in a factorial completely randomized design, with four replications. The rest period promoted a linear decreasing effect (P &lt;0.05) on the dry biomass of leaf blades in the two defoliation intensities. The dry biomass of stems showed an increasing linear effect (P &lt;0.05) according to the rest periods in the two defoliation intensities. Production was recorded at 2427.71; 2907.39; 3325.72 and 3749.45 kg ha−1 for the periods of 25; 35; 45 and 55 days, respectively. The dry matter content showed an increasing linear effect (P &lt;0.05) as a function of the rest periods evaluated in the two defoliation intensities. The rest period indicated a decreasing linear trend (P &lt;0.05) for the crude protein content in the two defoliation intensities. A decrease of 0.9 and 0.7 g kg−1 was verified for each day of the rest period. For each additional day in the rest period, there was an increase of 1.2 and 1.5 g kg−1 DM in the neutral detergent fiber content at intensities of 15 and 30 cm. The andropogon grass pasture managed with a 25-day rest period and defoliation intensity of 30 cm showed high leaf/stem ratio and good nutritional value.

title: The addition of the salmon oil in the freezing of equine semen

description: SUMARY The aim of the present study was to verify the effect of salmon oil addition on cryopreservation of equine semen. The experiment consisted of two treatments. Treatment 1 (T1) (control diluent), BotuCrio® was used without addition of salmon oil and treatment 2 (T2) (experimental diluent) BotuCrio® plus (with) 2% salmon oil. Three ejaculates of four stallions were used, totalizing 12 collections (n=12). Overall motility and progressive motility were evaluated by the Hamilton Thorn Research (HTR) Ceros 10.8 program, as well as the plasma membrane functionality through the hyposmotic test. Both treatments did not present statistical differences in relation to motility (T1 25,2±1,7 a, T2 29,7±1,9 a) and progressive motility (T1 11,0±1,1 a, T2 14,1±1,3 a). With respect to the hyposmotic test, the treatment 2 plus 2% of Salmon oil, presented better protection of sperm membrane functionality in relation to the control treatment (T2 77,3±1,0 a, T1 68,0±1,0 b). It can be concluded that salmon oil, although not altering the total and progressive motility, confers a better efficiency of sperm membrane functionality after thawing in equine semen.

title: An investigation of methicillin-resistant Staphylococcus pseudintermedius (MRSP) in domestic and shelter dogs in Montenegro (RS-Brazil)

description: SUMMARY The interaction established between man and their pets has been increasing progressively. The diagnosis of animals carrying methicillin-resistant Staphylococcus pseudintermedius (MRSP) becomes important since positive results for this opportunistic bacteria has been found in humans. The aim of this study was to investigate methicillin-resistant Staphylococcus pseudintermedius (MRSP) in domestic dogs attended in a veterinary clinic and shelter dogs. Anal and nasal swabs from 53 domestic dogs and 46 shelter dogs were collected between the months of August and October of 2015, resulting in 198 samples, which were sent for routine laboratory analysis and subsequently used for this study. Phenotypic tests for bacteria identification and susceptibility to oxacillin were performed for the investigation of MRSP. A total of 23 samples (11.6%) from 21 dogs were positive for S. pseudintermedius, however none of the isolates were MRSP. Nasal and anal swabs had similar positivity and two dogs were carriers of the bacteria in both analyzed sites (anal and nasal). Our results showed a higher positivity for S. pseudintermedius in domestic dogs compared to shelter dogs, as well as indicating the importance of collecting more than one colonization site. This is the first study to perform a comparison among different animal creating sites in Brazil.

title: Strategies to include sweet potato meal associated with the use of exogenous enzymes, in broiler chicken feed

description: SUMMARY This work evaluated the effect of including sweet potato meal (SPM), as an alternative to corn in broiler chicken diets, on performance, carcass yield, intestinal morphometry, organ biometry, meat quality and drumstick pigmentation. The study used 936 male Cobb-500 chicks. The experiment had a completely randomized, 3x2 factorial design, with three diet types. These included corn as the energetic ingredient in the standard diet (corn-soybean meal, CSM), and an increasing (ISP) and decreasing (DSP) inclusion of sweet potato meal as a corn substitute, in association with exogenous enzymes, for a total of six treatments with six repetitions and 26 birds per plot. During the period of 1 to 21 days, there was an interaction (P&lt;0.05) for the weight gain (WG) variable; the CSM diets promoted greater WG in relation to the ISP and DSP groups, when supplemented with exogenous enzymes. There was an increase (P&lt;0.05) in surface absorption of the jejunum villi and relative weight of the pancreas, and worse feed conversion (FC), for the ISP and DSP diets. With exception of the pancreas, for the entire period of 1 to 39 days the performance, yield of the carcass and cuts, meat quality, relative weight of the liver, and feet pigmentation variables were not affected (P&gt;0.05) by the factors evaluated. Sweet potato meal, independent of the inclusion program (ISP/DSP) and enzyme supplementation, could partially substitute corn in broiler chicken feed, guaranteeing good performance, carcass yield and meat quality.

title: Macronutrient and amino acids composition of milk replacers for dairy calves

description: SUMMARY Other than crude protein (CP), crude energy (CE) and crude fiber (CF) content, the adequate supply of essential amino acids (EAA) is an important factor in milk replacer evaluation. The aim of this study was to analyze milk replacer samples as regard to nutrients, especially EAA, composition and simulate the attainability of calves' requirements in different feeding systems. Forty-one milk replacer samples were collected from 14 brands and analyzed for nutrient composition. The near infrared spectroscopy technique was used for AA content estimation. Samples presented adequate levels of CP (21.2±2.90%) and ether extract (14.5±3.41%) for calves fed according to the conventional (4L/d), but not for intensive milk feeding system (&gt;6L/d). High values of CF were observed in the samples (1.6±0.86%). The EAA composition of milk replacer samples was lower than expected for a liquid feed supposed to replace whole milk. None of the analyzed samples presented adequate lysine (5.72±1.09% CP) or methionine (1.65±0.38% CP) to meet calves' daily requirements, regardless of feeding system. Higher crude protein milk replacers are needed. Alternatively, supplementation of milk replacers with EAA is recommended.

title: Antimicrobial activity and phytochemical prospection of vegetal extracts of Ocotea silvestris Vattimo-Gil and Ocotea diospyrifolia (Meisn.) against serotypes of Salmonella of poultry origin

description: SUMMARY The aim of this work was to evaluate the antimicrobial activity of plant extracts Ocotea silvestris Vattimo-Gil and Ocotea diospyrifolia (Meisn.) Mez against 10 serotypes Salmonella enterica of poultry origin of the highest incidence in the western region of Paraná, as well as to perform the phytochemical screening of the compounds of the two species. After obtaining the aqueous extract and the organic extracts (ethyl alcohol, ethyl acetate and hexane) was determined Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) by technique microdilution broth. Phytochemical prospecting performed according to qualitative methodology of precipitation and colorimetry. The extracts presented inhibitory and bactericidal activity in different concentrations (200 to 25 mg.mL-1) against the serotypes of Salmonella, varying according to the solvent extractor. The ethyl acetate extract presented the best results, followed by the alcoholic, aqueous and hexane extract. It is noteworthy that studies of antimicrobial activity with vegetable extract within the genus Ocotea are scarce, however, the Lauraceae family presents significant biological activities, mainly related to its essential oils. Phytochemical prospecting detected the presence of steroids and alkaloids in both Ocotea species, which may justify the antimicrobial potential found for Salmonella serotypes. It is concluded that these plants represent an alternative for the control of Salmonella in the poultry sector, reflecting a new perspective for studies with natural products.

title: Cassava bagasse and annatto colorific (Bixa orellana L.) in diets for slow-growing broilers from 30 to 90 days of age

description: SUMMARY The performance and breast skin color of slow-growing broilers from 30 to 90 days old fed diets with different inclusions of cassava bagasse and annatto colorific were evaluated. 308 slow-growing broilers were used in a completely randomized experimental design, in a factorial scheme with an additional treatment 3 X 2 + 1, with three levels of annatto colorific as a pigmentant agent (1%, 2% and 3%), two levels of cassava bagasse (10% and 20%) and an additional treatment (control diet), totaling seven treatments, four replicates and 11 broilers per experimental unit. Feed intake and feed conversion were affected by treatments, with interaction. The weight gain and final weight were influenced by the treatments and the best results were found for the inclusion of 10% cassava bagasse and 2% annatto colorific. There was no effect of treatment and no interaction on carcass yield. The color parameters L*, a* and b* were not influenced by treatments. The inclusion of 10% cassava bagasse and 1% annatto colorific for slow-growing broilers from 30 to 90 days of age is recommended. However, the use of these ingredients proved to be economically unfeasible.
