The objective of this research was to evaluate the influence of the planting density of cowpea on the production and weed suppression. The cowpea cultivars used were BRS Arace and BRS Guariba. The experiment was a split plot scheme in a randomized complete block design. The plots treatments were the densities and the subplots were the weed control methods. The BRS Arace populations that maximized the interception of irradiance were 166,667 and 181,739 plants ha-1 , before flowering and during the full bloom, respectively. The highest numbers of pods per plot and grain productivity were found in the populations of 128,000 and 121,000 ha-1 plants in BRS Arace.

The objective of this work was to evaluate the growth and productivity of BRS Quênia grass (Panicum maximum) submitted to nitrogen fertilization in Alta Floresta, MT. The highest dry matter yields occurred at doses 150 and 300 kg ha-1 . It was observed the occurrence of green leafhopper (Empoasca kraemeri) in the final period of the experiment. The BRS Quênia grass, under the conditions of the experiment, presented a high response to nitrogen fertilization. The dose of 150 kg of N ha-1 is recommended. Further studies are suggested to verify the susceptibility of BRS Quênia grass under the occurrence of the green leafhopper (E. kraemeri) and to identify the best conditions for the maximum performance of this forage in the region.

There is particular interest in knowledge of the physiological alterations that occur during the transition period, with the aim of understanding the intensity of metabolic alterations and their impacts on animal health. Due to the paucity of data on Moxotó females, related to the dynamics of the energy profile, protein, and mineral metabolites, the present study aimed to evaluate the profile of some blood biomarkers during the transition period. There was significant variation in metabolic dynamics related to energy, protein, and mineral profiles. There is a need for further study of other parameters, rendering them reference values in the different periods of gestation, particularly in the final third of gestation, when metabolic diseases can occur, putting the lives of the animals at risk.

The forest species popularly known as “pau-pretinho” (Cenostigma tocantinum Ducke) is one of the most used in urban arborization of the municipality of Manaus, Amazonas (Brazil). It is a native species to the Amazon and has low susceptibility to attack by pests and pathogens (GARCIA; MORAES; LIMA 2009). Throughout the year 2018, symptoms were observed on the leaves positioned in the lower third of the crown of C. tocantinum trees. The symptoms were characterized by areas of light brown color in the center and dark brown edges observed on leaves.

The objective of this study was to evaluate the effect of the replacement of maniçoba hay with spineless cactus on the metabolic response and renal function of lambs. Blood and urine samples were collected 55 days after introduction of the tested diets. No blood parameters were affected and the urinary concentration of urea, creatinine, and potassium was influenced by diet with decreasing linear behavior. The urinary glucose excretion index and the fractional urinary excretion of glucose increased linearly. The spineless cactus does not negatively impact in the metabolic profile and renal function of confined lambs, suggesting that it may replace up to 100% of the maniçoba hay.

The objective of this study was to verify the influence of boron (B) doses on soil boron availability and sunflower characteristics in Tangará da Serra - MT. A randomized block design with four replicates, six doses of B (0; 0,5; 1,0; 1,5; 2,0 and 4,0 kg ha -1 of B) was used, using boric acid. B content in soil, leaf B concentration, stem diameter, plant height, leaf diameter, mass of 1,000 achenes, shoot dry mass and yield were evaluated. All characteristics were influenced. The dose of 4 kg ha-1 provided toxicity to plants with negative effects on shoot diameter and shoot dry mass.

Questions persist regarding the best phosphorus (P) sources for tropical soils, especially for forest species. We evaluated the effects of four different P sources (single superphosphate - SSP; triple superphosphate - TSP; Arad reactive rock phosphate - ARP and Yoorin thermophosphate - YT) on nutrients accumulation, phosphorus use efficiency and growth on mahogany (Swietenia macrophylla King.) Mahogany is responsive to P fertilizer, however the high water soluble (TSP and SSP) and citric acid (YT) phosphorus sources had a similar effect on mahogany growth. It suggests that the seedlings producer can use any of them but should avoid the use of the ARP source in this stage of plant growth.

An outbreak of delayed enzootic ataxia in lambs in southern in the southern semi-arid state of Pernambuco. Affected lambs (n=18) showed symptoms of ataxia of the hind limbs, as well as difficulty in getting up and inability to walk, with a "dog sitting" posture. Histopathological examination of the spinal cord revealed vacuolization, axonal spheroids and myelin remains phagocytosed by macrophages and demyelination of the white matter. Low serum concentration of copper (6.88 µmol/L) was observed. Serum iron, zinc and molybdenum concentrations were at normal levels for the species. Clinical and laboratory data allowed concluding diagnosis of primary enzootic ataxia.

The objective of this work was to evaluate the reaction of chickpea genotypes to the Embrapa Vegetables germplasm bank for resistance to Meloidogyne incognita race 1 and M. enterolobii, aiming to identify sources of resistance to these root knot nematodes, and to verify haw this culture is affected by M. enterolobii. The two nematodes species were inoculated in the chickpea genotypes, and 104 days after inoculation were evaluated the egg mass index (IMO) and gall index (IG), number of eggs per gram of root (NOGR) and of the reproduction factor (FR). The data were submitted to individual and joint analysis of variance for the two species of nematodes and grouping of means of the treatments by Scott-Knott test. Was verified that for both species root-knot nematodes were not possible to identify resistant chickpea genotypes, but as field control is difficult, researches such as these to search for sources of resistance are important.

The objective of this work was to evaluate the phytotechnical characteristics and corn productivity in a consortium with forages, in different sowing modalities. It was evaluated: dry matter of corn plant, forage and total straw, plant heights, stem insertion, stalk diameters, ear and cob, number of rows of grains, ear masses, ear grains, ear corn, 1000 grains and productivity. The corn consortium with Urochloas did not change the phytotechnical characteristics compared to single corn. As there were no differences in productivity, the modalities of sowing in the line (seed mixed with the fertilizer) are a good alternative, since they reduce operational expenses.

The objective of the present work was to define the dose of N in the necessary cover to the greater development of the cultivated Vanda cultivar. Five treatments, doses of N applied in a cover (0, 30, 60, 90 and 120 kg ha-1 ) and four replicates, were given in equal doses at 10, 20, 30 days after transplantation (DAT). Harvest was carried out at 60 DAT where they evaluated: leaf number, plant height, leaf width, leaf length, plant width, stem diameter and total productivity. The 98.5 kg ha-1 dose of N in cover fertilization provided a better development in field cultivated lettuce.

The objective of this study was to quantify the concentration of hydrocyanic acid (HCN) in the morphological components of fresh maniçoba at different ages of growth and conserved as hay and silage. At the 30th day, the highest HCN values were found in all morphological components and at all ages the HCN concentrations were higher in the leaf. Silage and hay processes promoted a decrease of 67.03 and 91.15%, respectively, in the HCN values in relation to the fresh plant. Maniçoba leaf have a higher HCN content, especially when younger. Forage conservation methods reduce the concentration of HCN in maniçoba.

The interrelations between the number of tuberous root per plant, yield and dry matter content of roots of the Mandim Branca cultivar in 19 years of cultivation were evaluated, as well as the simple linear correlations of these variables with meteorological elements and drought in Jaguaruna, SC, Brazil. The three productive variables presented statistically significant correlations (p <0.05), positive and moderate among them. Mean temperature and precipitation presented negative and moderate correlation coefficients with yield and dry matter content. The maximum temperature presented a direct relation with the three productive variables. The number of tuberous roots per plant showed positive and strong correlations with maximum temperature and negative with drought duration in the first five months after planting. The duration of drought showed an inverse relation with the three productive variables. The results indicated that both water deficiencies and high precipitation in the post-planting period may decrease cassava productivity under the edaphoclimatic conditions of the present study.

One of the factors of greatest concern in current agriculture is the salinization of soil, especially irrigated land, with inadequate management of irrigation and fertilizers used in agriculture, one of the main determinants responsible for increasing the area with degraded soils. In the northeastern wilderness, evapotranspiration overcomes precipitation and, as a consequence, makes it impossible to percolate the water through the profile and, consequently, does not result in the leaching of soil salts. Considering the conditions present in the northeastern semi-arid region and the problems caused by salinization of soils, the present study had the objective of evaluating emergence and initial growth of pigeon pea as a function of two substrates and irrigation water salinity levels. The experiment was conducted at Green House, at the Federal Institute of Education, Science and Technology of Ceará - Campus Sobral. According to the results observed in the trial, the cultivar BRS Mandarim obtained a higher survival rate, with the increase of the level of salinity in clayey substrate; All variables analyzed were influenced by treatments; the cultivar normally germinated up to the level 3.0 dS m-1 , behaving like a plant with moderate capacity of tolerance to the salinity.

Cricopharyngeal achalasia is a disorder that causes decrease in the muscle relaxation of the esophageal musculature. As consequence, the food bolus has its passage interrupted at the oropharynx, through the cranial esophagus sphincter. This work reports the case of a Golden Retriever dog, which after anamnesis and clinical evaluation, was diagnosed through contrast radiography with Cricopharyngeal Achalasia. The treatment consisted in surgery, using the cricopharyngeal myectomy technique. The results of the surgery were favorable, and the patient was monitored for six months after the procedure, ensuring that there was no recurrence of clinical signs.

This work aimed to evaluate the interference of doses of potassium in arugula culture. The experiment was conducted in a rural property in Borborema - SP. A randomized complete block design with five treatments (0; 50; 100; 150 e 200 kg ha1 de KCl) and four replications was used. Were evaluated Dry mass (g); Root size (cm); Number of sheets. There was no significant difference between the treatments and the control in any parameter evaluated. It is concluded that the supply of this nutrient via fertilization does not provide increases in arugula productivity.

The objective of this study was to investigate the effects of diets with cactus cladodes on histomorphometric parameters of the rumen epithelium in goats. The animals submitted to the control diets had a dorsal sac with a greater thickness of the keratinized layer and nonkeratinized layers of the ruminal epithelium compared to those fed with Nopalea cochenillifera Salm-Dyck, without significant difference in treatment with the Opuntia stricta [Haw.] Haw. (O.E.M.). There was no significant difference (P<0.05) for any parameters analyzed in the ventral sac of the rumen. The diets based on Tifton-85 hay associated or not with cactus cladodes O.E.M. can cause a change in the morphology of the ruminal epithelium.

This work aimed to evaluate the quality of pre-ready mixtures for chocolate-flavored cake. The sensory analysis employed approached the acceptance test and the intention to buy test and the ideal test, being performed by 120 consumers. The results obtained through ANOVA indicated that the C sample was the one that presented the highest acceptance, in contrast the F sample showed less acceptance. For the intention of purchase test it was observed that it was proportional to the acceptability of the samples. The Internal Preference Map proved the results of ANOVA and the intention of purchase test.

According to the Sanitary Surveillance, good handling practices are procedures that must be adopted by food service providers in order to ensure hygienic sanitary quality and their compliance with sanitation legislation. The objective of the present study was to evaluate the physical and hygienic conditions of snack bars in the city of Presidente Figueiredo - AM, through a questionnaire of 51 questions, which was adapted from Resolutions 216/2004, 275/2002 and Municipal decree 125/2002. As an overview of the checklist, 68% of the snack bars were considered regular; 29% were good and 3% were bad. Despite the favorable result, many aspects regarding handling food still need to be improved in Presidente Figueiredo’s snack bars.

It was verified the dynamics of biomarkers of cardiac muscle activity (troponin I and CK-MB) in Saanen goats in the peripartum period. There was no significant variation (P>0.05) in the variables in the prepartum, delivery and postpartum periods. Highly negative correlation was observed between plasma ß-Hydroxybutyrate concentration with glucose (r=0.60, P<0.0001) and moderately negative between ß-Hydroxybutyrate and troponin (r=0.45, P<0.0001). Blood levels of Troponin I and CK-MB are detectable in the blood of Saanen goats in the transition period, and these data can be used as reference values for metabolic profile study in different metabolic and reproductive conditions. Scientific investigations are needed to better understand the specific effect of the transition period on myocardial integrity and interaction between biomarkers of energy metabolism in dairy goats.

The cavitary corpus luteum is the premature closure of the place where ovulation occurred. Its basic cause is a failure of the pituitary gland, which ends up releasing a quantity of insufficient luteinizing hormone, for the adequate development of the corpus luteum. We describe at a present case of cavitary corpus luteum, diagnose by histopathological examination, in one of the ovaries of a cow slaughtered in a slaughterhouse. In live animals, the cavitary corpus luteum by rectal palpation has the same characteristics as a normal, large and swollen corpus luteum. It is diagnosed only bay ultrasonography, ovariectomy accompanied by histophatology or post-mortem. The objective of this study is to report the case of cavity corpus luteum emphasizing its importance.

The objective of this study was to evaluate the effect of the monensin increased in the diet of lambs, in feedlot and slaughtered at 45 kg on performance. Were used 12 lambs in a completely randomized design, with the animals distributed in two treatments with six replicates per treatment. Namely: 1) Control diet and 2) Diet increased with monensin. Data were analyzed by GLM procedure of Statistical Analysis System (SAS) and means compared by t test. The use of monensin increased daily weight gain, but didn’t affect consumption. The use of monensin in the diet of confined lambs may be favorable because it can reduce the time of confinement.

Cobalt (Co) is a very important mineral in animal metabolism, mainly for the synthesis of vitamin B12. The objective of this study was to assess the hepatic concentration of Co in goats and sheep in the wilderness of the State of Pernambuco, taking into account factors of seasonality, species and sex. It was observed that hepatic concentrations of Co are at adequate levels and were not influenced by the seasonal period, species and sex. The data serve as a reference for the diagnosis on Co in these species created in the wilderness Pernambucano, but more research is necessary, since the region is known to present animals with several deficiencies of macro and microminerals.

The botanical composition and grazing behavior of goats were evaluated and grazed plants were identified in silvopastoral system area and different seasons of the year in the Mid-North of Brazil, Piaui state. Six adult goats were arranged in completely randomized desing, factorial 3x5, with three seasons of the year (dry, transition and rainy) and five months of evaluation, and six replicates. The time of year influences the forage production and the composition of the pasture, besides the grazing behavior. Regrowths of woody species participate in the diet of goats, being important the management of areas of silvopastoral systems with maintenance of the known species that make up the diet of these animals.

The objective of the study was to report a left unilateral aseptic necrosis of the femoral head in a female dog. It had a history of trauma in the left hind limb, keeping it raised when walking, with pain and discomfort to palpation. It was submitted to a dorsal x-ray examination with a morphological alteration report of the left proximal epiphysis and presence of radiolucent areas, suggestive of the condition diagnosed in the clinical evaluation. She was referred for left femoral head excision surgery and then physical therapy. Because it is easily confused with other locomotor lesions, clinical evaluation together with radiographic examinations is extremely important in this disease.

Rhipicephalus (Boophilus) microplus is the ectoparasite that most affects the cattle herds in the country, responsible for considerable economic losses, due to the harms that cause to the health of the animals. The objective of this work was to evaluate the essential oil of the Indian Clove and the Neem oil for the in vitro control of this ectoparasite. The concentrations of 0.5%, 1% and 2% of the oils were used. The essential oil of Clove of India demonstrated 100% effectiveness at 2% and 97.09% of ovariostatic activity. Neem oil, on the other hand, was not effective in mortality, but it demonstrated satisfactory results ovariostatic activity.

The objective was to evaluate the pregnancy rate using progesterone (P4) after 4 days of the FTAI. A total of 126 multiparous cows were used. The experimental design was completely randomized, with two treatments (T1 and T2), being: T1 - Control and T2 - P4 injectable D14. The cows were submitted to the same hormonal protocol of 3 treatments until the day of the FTAI, differentiating only in the D14. After 40 days of FTAI, the following pregnancy rates were obtained: T1-55.6% and T2-49.20%. It is concluded that the use of progesterone after 4 days of AI does not show differences of conception rate in relation to the control group and its use reduces the profitability of the productive system.

The objective of this study was to evaluate the physical profile of the broiler females fed with increasing levels (0, 3, 6, 9 and 12%) of raw soybean meal in the seven, 14, 21 and 42 days of life. A total of 250 one - day - old male broilers of the Cobb ® lineage were used, the experimental design being entirely random, with five treatments with five replicates containing 10 birds each. There was a significant linear effect of soybean inclusion levels in all evaluated periods. It was concluded that the inclusion of soybean yield levels negatively influences the broiler femur from one to 42 days.

The objective of this study was to characterize the social behavior and the man-animal relationship of dogs attending a public park, in the South Zone of Recife, Pernambuco. For this purpose, questionnaires containing questions regarding the purpose of breeding, frequency of walking and the occurrence of abnormal behaviors were applied to sixty tutors of dogs attending a public park. The data showed that the breeding conditions and the interaction that the dogs maintain with the tutors have generated changes in the social behavior of these animals and the regularity of the walks has markedly reduced the levels of aggression and animal anxiety, promoting adequate socialization and welfare.
