1. Use of Sunflower and Soybean as Bioindicators to Detect Atrazine Residues in Soils
RESUMO: A atrazine é seletiva para milho, cana-de-açúcar e sorgo e pode interferir em culturas sucessoras, como girassol e soja. Apesar da problemática, são poucos os estudos acerca do efeito residual desse herbicida nessas culturas. Assim, o objetivo desta pesquisa foi avaliar o efeito residual da atrazine por meio da biodisponibilidade do herbicida em

2. Developments of reproductive management and biotechnology in the pig
Abstract This review aims to describe changes in production environment, management tools and technology to alleviate problems seen with the present hyperprolific sow model. Successful parturition in the pig includes the possibility to express adequate maternal behaviour, rapid expulsion of piglets, complete expulsion of placenta, elimination of uterine cont

3. Identification of differentially expressed microRNAs in middle-size ovarian follicles of Meishan and Duroc sows
ABSTRACT This study aimed to investigate the roles of miRNA in the development of ovarian follicles in sows with high ovulation rate. The miRNA expression profiles in middle-size ovarian follicles between Meishan and Duroc sows were characterized by Affymetrix miRNA GeneChip. Seven differentially expressed miRNA were identified. KEGG pathways analyzed the pr

4. Perdoar e Punir em tempos de Transição: O Recurso de Graça no Conselho de Estado do Brasil (1828-1834)
Resumo O objetivo desse trabalho é discutir os principais aspectos relacionados ao modo como o recurso de graça era tratado no segundo Conselho de Estado brasileiro. Foram analisados cerca de 160 casos presentes nas atas do conselho. Vimos que a maioria das decisões do imperador seguem a opinião do conselho; os casos se relacionam principalmente a crimin

5. Desempenho e termorregulação de porcas lactantes alojadas em diferentes localizações no interior de um galpão com sistema de resfriamento evaporativo em ambiente tropical
ABSTRACT The effects of housing lactating sows at different locations in a shed with evaporative cooling system (ECS) on their thermoregulation and reproductive and productive performance of the sow and the litter in summer were determined. 34 females were used in the three lines of cages at these locations: near the pad cooling; in the middle of the shed an

6. Leaching of Imidazolinones in Irrigation Systems in Rice Cultivation: Sprinkling and Flooding
RESUMO: Herbicidas do grupo das imidazolinonas têm sido utilizados em arroz irrigado e apresentado longa persistência no solo, principalmente em áreas de várzea, com baixa drenagem, podendo ocasionar contaminação ambiental. Objetivou-se, com este trabalho, avaliar a lixiviação e o residual dos herbicidas pertencentes ao grupo das imidazolinonas em si

7. Reproductive performance of fixed-time artificial insemination in swine and factors for the technology success
RESUMO: A inseminação artificial em tempo fixo (IATF) surge como uma biotecnologia para definir o melhor momento para realizar uma única IA, reduzindo o número de células espermáticas por fêmea inseminada. Os protocolos de IATF podem se basear na detecção do estro ou na data de desmame e têm como objetivo sincronizar a ovulação a partir do uso de

8. The influence of sowing dates on the oil content and fatty acid composition of standard, mid-oleic and high-oleic types of sunflower (Helianthus annuus L.)
Abstract This study aimed to determine the oil ratios and fatty acid compositions of sunflowers grown in the warm climate of the Çukurova region at different sowing dates. It was found that the crude fat ratios of standard, mid-oleic and high-oleic sunflower types were 42.57%, 39.35% and 39.07%, respectively. Crude oil ratios of high-oleic and mid-oleic su

9. Arginine improves nutritional quality of sow milk and piglet performance
ABSTRACT The objective of this study was to evaluate the effect of L-arginine supplementation in lactation diets on the productive and reproductive performance of pluriparous sows and their litters. Seventy-six sows of the same genetic line were assigned to four treatments in a completely randomized design with 19 replicates. The experimental unit was the so

10. Correlation between urinary tract infection and reproductive performance of sows
ABSTRACT This study aimed to assess the prevalence and influence of urinary tract infection on the reproductive performance of sows. The animals underwent urine tests using reagent strips and diagnosed as positive or negative. They were then divided into two groups of 30 positive and 30 negative sows for urinary tract infection. Each sow was considered an ex

11. Application of computational fluid dynamics on a study in swine facilities with mechanical ventilation system
ABSTRACT: Ventilation systems used in swine facilities deserve to be studied because they directly affect productivity in the pig farming sector. Bearing this in mind the uniformity of air distribution and temperature is essential to animal welfare in this breeding environment. Thus, the purpose of this study was to identify whether changes in air entrances

12. Microenvironments in swine farrowing rooms: the thermal, lighting, and acoustic environments of sows and piglets
ABSTRACT: The present research hypothesized that the thermal, lighting and acoustic environments in commercial swine farrowing rooms vary over time and from crate to crate. This study was conducted on 27 replicates in two commercial farrowing rooms in North Central Indiana, each equipped with 60 farrowing crates. Temperature, relative humidity, light intensi
