title: Ingestive behavior of steers finished on soybean hull and/or white oat grain

description: Abstract The objective of this research was to measure the ingestive behavior of steers finished exclusively with concentrate containing soybean hulls (ground) and/or white oat grain.We used 32 steers with Charolais or Nellore predominance.The animals were randomly distributed in the treatments, blocked according to genetic predominance, and allocated in individual pens. Diets were isonitrogenous, being the treatments: Soybean hulls; White oat grain or the Mixture (equal parts), plus limestone and protein nucleus. Steers that received the diet based on soybean hulls remained more time in idle compared to the ones that received the mixture, and these remained more time in idle than the steers that received the diet based on white oat grain. Steers that received the diet based on soybean hulls ruminated less time than the steers fed the mixture, and these less time than those fed white oat grain. Exclusively concentrate diets based on soybean hulls although presenting high soluble fiber content in neutral detergent, are not sufficient to promote an appropriate ingestive behavior of steers of Charolais or Nelore racial predominance.

title: Effect of raising the cutting height in corn on performance and carcass traits of lambs

description: Abstract This experiment was conducted to evaluate the effect of raising the cutting height of the corn plant destined to silage production, in relation to the dry biomass production and possible influence on the performance of confined lambs. The treatments tested were: SM20: Corn silage harvested at 20 cm height. SM80: Corn silage harvested at 80 cm height. Cutting at 80 cm from the ground reduced the dry biomass production by 2.375 kg DM ha-1, but did not reduce the carrying capacity and improved the digestibility of the feed by 4.59%, besides improving the carcass conversion, carcass transformation efficiency and carcass yield by 1.04%, 4.68% and 2.20%, respectively for animals fed silage of corn cut at 20 cm from the ground. Production of silage harvested farther from the ground provides smaller volumes per area, but increases the quality of the final feed and improves the performance of the animals.

title: The use of the sweet potato branches in the hay production

description: Abstract Sweet potato branches have satisfactory characteristics for animal feed, but have not been exploited in the form of hay. The objective of this work was to evaluate the use of the sweet potato branches for the hay production and genetic divergence in sweet potato clones. Were evaluated ten sweet potato clones, conducted on the field in randomized blocks and 5 repetitions. Dry matter content, green mass and dry mass yield (DMY), leaf and stem ratio of branches and total and commercial root production (CRP) were determined. Gotten the hays, were evaluated the characteristics: DM, CP, NDF, ADF, lignin, starch, soluble sugars, macro and micronutrients. The genetic divergence among the sweet potato clones was estimated. The UFVJM-54 clone allied high CRP with bigger DMY. The hay presented content of CP ranging from 11.99% to 15.09%, NFD 47.22 to 55.55%, ADF 22.92 to 28%, and 6.87 to 13.72% of LIG. In a general way, the contents of minerals in hays were satisfactory. The clones were separated into 5 different groups. The sweet potato branches can be used for the hay production. The UFVJM-37, UFVJM-46 and UFVJM-54 clones are recommended for crossing with the other genotypes.

title: Effects of supplementation with combination of polyunsaturated oils in diet of horses in maintenance and during marcha training

description: Abstract This study aimed to evaluate the effects of supplementation with polyunsaturated oil on lipid and mineral blood biomarkers in two different groups of horses. Was used 6 healthy horses in maintenance (MT-g) and 10 healthy horses in marcha gait training (GT-g). The MT-g and the GT-g received 100mL and 300mL/day/animal of combination of polyunsaturated oils, respectively, during 8 weeks. Blood was collected in pre-test and after 4 and 8 weeks, after overnight fasting and it was measured: total cholesterol, HDL cholesterol, LDL cholesterol, triglyceride, NEFA, LPS, glycerol, Ca, P, Mg, and Cl. The supplementation produced significant increase in NEFA and reduction in lipase in both groups. In addition, the LPS content in both groups had a large decrease (~35%) from the pre-test to the 8th week of supplementation. In the MT-g, the LDL cholesterol and glycerol increased significantly after 4 weeks but returned to the pre-test levels after 8 weeks, and the triglyceride content decreased (~62%) after 4 weeks. The total cholesterol concentration in the GT-g increased after 4 weeks (~70%), but after 8 weeks it decreased to levels similar to those observed in the pre-test. The mineral biomarkers increased in the MT-g and GT-g, after 8 weeks. In the MT-g and in the GT-g, Ca decreased. In conclusion, supplementation with a combination of polyunsaturated oils increased NEFA concentration and reduced LPS activity in both groups, unlike the concentrations of the other biomarkers that showed different variations between groups, indicating that both NEFA and LPS the changes in their concentrations during supplementation may be more sensitive and more indicated for these types of evaluation. In addition, some blood mineral concentrations reduced significantly in both groups of horses, and thus, they need to be evaluated in horses under chronic oil supplementation

title: Leaf blade area estimate of Digitaria pentzii under different cutting Heights

description: Abstract Pasture studies require information on leaf area, as it is one of the main parameters for evaluation of plant growth. Thus, the objective of this study was to estimate the leaf blade area of pangolão grass (Digitaria pentzii Stent.) using non-destructive methods by regression model analysis. The experimental design consisted of randomized blocks, with three cutting heights (10, 15, and 20 cm) and four replications. Three hundred leaf blades of pangolão grass were randomly collected, and their respective lengths (L) and widths (W) determined using a digital caliper. The leaf blade area of pangolão grass was estimated by the gravimetric method, using linear and power regression models to explain the leaf blade area as a function of the product of L and maximum W. The real leaf blade area presented an average value of 18.64 cm2, ranging from 4.29 to 45.95 cm2. The leaf blade area of pangolão grass, regardless of cutting height, was estimated with greater accuracy by the power model. The power model, Ŷ=LW1.007, can be used to estimate the leaf blade area of pangolão grass based on leaf blade L and W values.

title: Use of milk with different fat concentrations as extenders for equine cooled semen

description: Abstract Two trials were performed to verify the viability of extenders equine cooled semen. The objective of the first trial was to verify the efficacy of whole and semi-skimmed UHT milk compared to skim milk. Fresh semen samples were analyzed and later diluted in UHT whole milk, semi skimmed and skimmed milk. Sperm motility and vigor, CFDA / PI and HOST tests were performed post-dilution (0h), and in semen cooled at 5oC after 24 and 48h. There was no difference between the 3 extenders, for sperm motility (p = 0.9880), vigor (p = 0.7249), CFDA / PI (p = 0.3882) and HOST (p&gt; 0.01). There was a decrease in semen quality over time (p &lt;0.01), regardless of the extender used. It can be stated that in the absence of skimmed UHT milk, semi-skimmed and whole milk can be used since they do not impair the quality of refrigerated semen stored for up to 48 hours. In the second trial the objective was to verify the efficacy of the skim milk compared to commercial extenders (Botusemen® (BS) and Botusemen Special® (BSS)). Soon after semen collection, the samples were diluted with UHT skim milk (LD), Botusemen® (BS) and Botusemen Special® (BSS). Semen analysis followed the same protocol as the first experiment. BSS-cooled semen showed higher HOST and CFDA / PI (p &lt;0.001) in 24h and 48h indicating that BSS diluent promotes increased sperm longevity compared to the others analyzed.

title: Effect of feeding crude or treated tung meal (Aleurites fordii) in the diet of Rhamdia quelen on growth, digestive enzymes and biochemical parameters

description: Abstract This study evaluated the addition of tung (Aleurites fordii) meal to the feed of Rhamdia quelen, as an alternative to animal protein sources. Silver catfish juveniles were fed different diets which included crude tung meal, chemically treated tung meal and a control without tung meal. The chemical treatment was based on the sequential application of acid and alcohol solutions and reduced the phytic acid from 1.63 to 0.61% and condensed tannin content from 0.025 to 0.018%. The nutritional response of fish to these ingredients was evaluated over nine weeks, based on growth performance, digestive enzyme activity and biochemical responses. After nine weeks, the diet containing crude tung meal caused reduced growth (weight: -57.9%; total length: -21.09%; specific growth rate: -99.74%). This diet also reduced acid protease and lipase activities, decreased concentrations of glucose, cholesterol and triglycerides in plasma and decreased liver glycogen and glucose concentrations. However, after nine weeks, fish fed with treated tung meal showed higher growth (weight, total length and specific growth rate similar to control) and reduced metabolic changes, possibly due to the removal of antinutrients and toxic substances. At the 32% level of inclusion, the chemically treated tung meal can be considered an alternative protein source for silver catfish.

title: Reproducibility and repeatability of radiographic measurement of the cardiac silhouette in poodles

description: Abstract The potential of reproducibility and repeatability of a semi-automatic system of radiographic measurement was evaluated. For this purpose, the vertebral heart score (VHS) and normalized cardiac area (NCA) were evaluated in radiographs of healthy poodles and of patients with mitral regurgitation. Considering the subjective aspect of the cardiac silhouette analysis by different observers, it is believed that even with a semi-automatic system this evaluation could be affected by the previous experience of the observer in radiodiagnosis. Fifty seven thoracic images were analyzed by two groups of observers with different levels of experience in radiology: (A) without experience (n = 2) and (B) with experience (n = 2). Regardless of radiodiagnostic experience it was observed good repeatability and reproducibility for VHS, and also for ACN in observers with experience in radiodiagnostics and previous familiarity with the software.

The mineral biomarkers increased in the MT-g and GT-g, after 8 weeks. In the MT-g and in the GT-g, Ca decreased. In conclusion, supplementation with a combination of polyunsaturated oils increased NEFA concentration and reduced LPS activity in both groups, unlike the concentrations of the other biomarkers that showed different variations between groups, indicating that both NEFA and LPS the changes in their concentrations during supplementation may be more sensitive and more indicated for these types of evaluation. In addition, some blood mineral concentrations reduced significantly in both groups of horses, and thus, they need to be evaluated in horses under chronic oil supplementation

title: Deteriorating potential of the mesophilic microbiota, psychrotrophic, termoduric and spore raw milk

description: Abstract Considering that technological problems and economic losses are basically caused by spoilage microorganisms on dairy industry, therefore the aim of this study was to quantify the mesophilic aerobic, psychrotrophic, thermoduric and aerobic spore-forming in raw milk produced in northern Paraná and also verify the proteolytic and lipolytic capacity of these microorganisms. Twenty samples of raw milk were analyzed and were determined mesophilic aerobic, psychrotrophic, thermoduric mesophilic, psychrotrophic thermoduric and aerobicspore-forming counts and proteolytic and lipolytic capacity from each group. The average counts of aerobic mesophilic were 1,79x106CFU/mL, above the limit established to Normative Instruction 76 (3,0x105CFU/mL); 55% samples had scores within the standards. Psychrotrophic counts ranged from 1,0x102 to 9,9x106CFU/mL and in 30% samples this count was higher than mesophilic. The average mesophilic thermoduric was 2,4x104CFU/mL, psychrotrophic thermoduric was 1,7x102CFU/mL and aerobic spore-forming was 5,0x101CFU/mL. As for the spoilage profile, all groups showed higher lipase and proteolytic activity, with a predominance of lipolytic bacteria. The values found indicates the inappropriate hygienic-sanitary management during milking and maintaining molk refrigerated for long periods until pasteurize, it can favorsthe proliferation of spoilage microbiota, which can promote significant changes in the quality and yield of milk and dairy products, even after the heat treatment.
