title: Effects of in feed removal of antimicrobials in comparison to other prophylactic alternatives in growing and finishing pigs

description: ABSTRACT The utilization of antimicrobials in animal production, causes selection of resistant bacteria. The objective of this study was to compare the utilization of alternatives in association with preventive antibiotic therapy in swine feed during the growing and finishing phases. 1,045 animals were used from 60 to 190 days of age and were subjected to six treatments with 16 repetitions as follows: 1) antibiotic free; 2) antibiotics; 3) prebiotic; 4) probiotic; 5) essential oils; and 6) organic acid. Animals were weighted, and clinical history was recorded including mortality and diarrhea. At the abattoir, pneumonia index and gastric ulcers were investigated. The cost for each treatment was discussed. No difference between treatments were observed (P&gt;0.05) regarding feed conversion rate (2.64±0.03), overall average weight gain (107.06±0.9kg), average daily weight gain (856.49±7.7g) and carcass weight (92.4±0.7kg). The application injectable drugs in animals presenting clinical symptoms, represented US$ 0.56/intervention, without difference between the treatments (P&gt;0.05). Furthermore, independently of the treatment, high frequency of pneumonia was observed (&gt;0.90). No difference for the degree of gastric ulcer nor feces consistency were observed (P&gt;0.05). The utilization of antibiotic therapy and alternatives to antibiotics in feed did not produce benefits to the production indices and sanitary performances of the animals.

title: Carnauba (copernicia prunifera) straw as an alternative bedding material for dairy cows housed in a Compost barn system

description: ABSTRACT The replacement of bedding in compost dairy barns (CB) comprises a recurrent management practice, but bedding materials are often not readily available in all regions and the choice of alternative materials is necessary. The objective was to evaluate the thermal attributes of carnauba straw (CS) bedding in compost dairy barn facilities. Environmental monitoring operations were performed at a commercial farm located in Northeast Brazil. Mini weather stations were used to evaluate environmental variables. The THI was evaluated as one of the comfort parameters. Analysis of the spatial distribution of bed surface temperature (BST) in the CB was performed using geostatistical techniques. The cows remained out of the comfort zone according to THI results. The BST indicated satisfactory performance and from the thermal point of view can be used as alternative bedding material in CB facilities. However, it was observed that the CS showed fast biomass degradation compared to conventional materials, widely known. In addition, inadequate temperature values (&lt; 45°C) were found in the deeper of the CS bed, signaling higher risks of pathogenic microbial activity. Additional studies are needed for searching the proper management plans that increase the life span of the bed formed by carnauba straw.

title: Does the lowering strategy before the stockpiling period modify the marandu palisade grass production and structure?

description: ABSTRACT The objective was to identify lowering strategies for Urochloa brizantha cv. Marandu in the beginning of the stockpiling period that increase forage production and improve the structure of stockpiled canopies. Three lowering strategies were evaluated: maintenance of marandu palisade grass with 15cm four months before the stockpiling period; maintenance of palisade grass with 30cm for four months, and lowering to 15cm before the stockpiling period; and maintaining of palisade grass at 45cm for four months, and lowering to 15cm before the stockpiling period. The experimental design was completely randomized, with four replications. At the end of stockpiling, the number of reproductive tillers and forage mass were higher in the canopy under 15/15cm than in the others; the percentage of live leaf was higher in the canopy under 45/15cm than under 15/15cm. Forage production during the stockpiling period was higher in the canopy under 15/15cm and lower in the under 45/15cm. Maintaining 15cm marandu palisadegrass for four months before the stockpiling period increases forage production during this period. The lowering of the marandu palisadegrass from 45 to 15cm at the beginning of the stockpiling period improves the structure of the stockpiled canopy.

title: Morphogenesis of stockpiled Marandu, Piatã, Xaraés and Paiaguás brachiariagrass cultivars

description: ABSTRACT The objective this study was to identify differences in the morphogenic patterns of four Urochloa brizantha cultivars (marandu, piatã, xaraés and paiaguás grasses) during the stockpiling period. A completely randomized design was used, with three replications, in experimental plots of 9m². The evaluations took place over 2 years. The grasses were stockpiled for 92 (Year 1) and 95 (Year 2) days. The leaf appearance rate of paiaguás grass was higher, compared to other grasses. In Year 1, the stem elongation rate of xaraés grass was higher than other grasses. At the end of stockpiling period of Year 1, the tiller population density (TPD) was higher in the paiaguás grass, intermediate in the xaraés and marandu grasses and lower in the piatã grass. At the end of the stockpiling period in Year 2, TPD was higher in the paiaguás grass canopy, intermediate in the marandu and piatã grasses canopies, and lower in the xaraés grass canopy. Paiaguás grass has greater leaf growth during the stockpiling period and is therefore suitable for use under stockpiled grazing. Xaraés grass has high stem elongation during the stockpiling period, which is why its use under stockpiled grazing must be accompanied by adjustments in pasture management.

title: Tillering dynamics in spring and summer of marandu palisade grass pastures previously used under deferred grazing

description: ABSTRACT This work was conducted to evaluate the effect of deferred pasture condition of Brachiaria brizantha cv. Marandu in the late winter on tillering during the growing season. The treatments were three pasture conditions at late winter: short pasture, tall pasture and tall/mown pasture. In September and October, tiller appearance rate (TApR) and tiller mortality rate (TMoR) were greater in the tall/mown pasture. In November and December, tall pasture presented greater TApR. From November to January the TMoR was greater in the tall pasture. The tiller stability index of short and tall/mown pastures were greater in October. The short pasture presented a greater tiller number than the tall and tall/mown pastures during the entire experimental period. Deferred and short pasture of marandu palisade grass at late winter presents in general lower tiller mortality and higher population density of tillers from the early spring onwards, in comparison to tall pasture. The mowing of marandu palisade grass with high forage mass at the late winter, although it only temporarily compromises the population stability of tillers, also stimulates its fast tillering from spring on.

title: Evaluating performance and determining optimum sample size for regression tree and automatic linear modeling

description: ABSTRACT This study was carried out for two purposes: comparing performances of Regression Tree and Automatic Linear Modeling and determining optimum sample size for these methods under different experimental conditions. A comprehensive Monte Carlo Simulation Study was designed for these purposes. Results of simulation study showed that percentage of explained variation estimates of both Regression Tree and Automatic Linear Modeling was influenced by sample size, number of variables, and structure of variance-covariance matrix. Automatic Linear Modeling had higher performance than Regression Tree under all experimental conditions. It was concluded that the Regression Tree required much larger samples to make stable estimates when comparing to Automatic Linear Modeling.

title: Availability of siblings in Brazil: a methodological study on kinship relationships

description: Abstract When fertility declines, it is not only the number of children that becomes smaller, but the number of siblings as well. To determine changes in the number of siblings over time in Brazil, this study uses a method that is designed to estimate, through mathematical models which use only fertility and mortality rates, the availability of surviving siblings in different cohorts. The results indicate that, at the beginning of the demographic transition, the mean number of the born alive siblings is established at high levels and suffers a sharp decline during the transition, mainly due to falling fertility. They also show that the mean number of the surviving siblings at older ages tends to be very similar for older and younger cohorts. However, the mean number of surviving siblings during the childhood of these cohorts tends to differ greatly. This is due to high mortality, especially infant mortality, on the one hand and, on the other, from fertility decline which reduces the number of live births in more recent cohorts while the reduction of mortality increases their chances of survival. The study's conclusion points out the following trends: the mean number of surviving siblings will tend to settle at lower levels in coming years and the mean number of surviving siblings tends to be increasingly closer to the mean number born alive. Despite current low levels of fertility, it would be incorrect to speak of the extinction of siblings and, consequently, of cousins, uncles, etc.

title: Factors related to the quality of life elderly people from a Quilombola Community of Paraíba

description: Abstract The article presents factors related to the quality of life of the elderly in a quilombola community in Paraíba. A cross-sectional study, conducted with elderly people of both sexes, residents of the Quilombola community Caiana dos Crioulos, Alagoa Grande/PB, Brazil, registered in the E-SUS as residents of that community. The dependent variable is health-related quality of life (HRQOL) and the independent ones are socioeconomic-demographic profile, health status, nutritional status and muscle strength. Spearman correlation, simple and multiple linear regression (CI 95%; p&lt;0.05) were performed to verify the relationship between the variables. Forty-five elderly people (66.6% women) were evaluated, with a mean age of 71.3 years, 42.2% of which had poor HRQOL in the physical component and 44.4% in the mental component. Symptoms indicative of depression, the number of chronic non-communicable diseases (NCDs) and the sitting-rising test together explained 37% (R²=0.379, p&lt;0.05) of poor HRQOL. Symptoms indicative of depression, the number of CNCDs and the siting and rising test are related to poor HRQL in this population in the physical component. Comprehensive and priority care by public health services is suggested in order to control and reduce the occurrence of physical and psychological diseases and maintain muscle strength.

title: Who needs housing in Latin America? Co-residence in housing deficit estimates

description: Abstract Two long and persistent phenomena in Latin America are poor quality housing and the response of the co-residence of homes and families out of necessity, with a wide dispersion in the way they are measured. The objective of this article is to define the problem conceptually and to unravel the theoretical matrix that underlies the different ways of measuring the quantitative component of the housing deficit, especially with regard to the accounting, or not, of secondary family nuclei as requesting units of living place. Secondly, it contributes to the discussion based on the demographic analysis of the co-residence structures empirically analyzed in the metropolitan regions of Bogota and Buenos Aires. As a result, it was possible to identify that the co-residence of nuclei and households can be a non-exclusive functional residential strategy for the poorest groups, especially in the Bogotan context, and that its existence facilitates mutual care inside the dwelling. However, co-residence also hides an unsatisfied demographic demand, concealed by complex dysfunctional residential arrangements, highly representative numerically in the two contexts analyzed. The treatment of these situations raises a debate on the targeting of public policy to solve the housing deficit, and the situations that should be prioritized to guarantee the right to housing from the perspective of housing needs and not just market needs.
