RESUMO Objetivou-se com este experimento avaliar o efeito da inclusão de torta de mamona destoxifi cada (TMD) na ração de poedeiras comerciais sobre o desempenho e a qualidade interna ABSTRACT This experiment aimed to evaluate the use of detoxifi ed castor cake (DCC) in the diet of laying hens on performance and internal and external quality of eggs. A total of 200 laying hens with 40-50 weeks of age, of Hy-Line W-36® line, with 1543±34g body weight, were distributed in a completely randomized design with fi ve treatments (0, 5, 10, 15 and 20% of DCC in diet)

Kiwifruit (Actinidia deliciosa cv. Hayward) was introduced into Northwest Portugal at the early 1970's increasing its importance up to date. The main objective of orchard management is to find out the cultural techniques suitable for the region, in order to obtain good yield and quality fruit. Winter chilling (≤ 7.2ºC) plays a significant role in kiwifruit break dormancy. Insufficient chilling can be countered by chemical agents as hydrogen cyanamid (Dormex). The objective of this research was to quantify the efficiency of hydrogen cyanamide (0%, 4%, and 6%) on bud break dormancy and yield and fruit quality. Experiments were carried out over two years on a mature 'Hayward' kiwifruit orchard. The results showed that 4% Dormex was the most efficient in increasing marketable yield due to increase of flower bud formation and higher level of fruit set. There were no significant differences among treatments in soluble solids content, flesh firmness and dry weight. Titrable acidity showed higher values with increased Dormex concentration.

The sampling methods for soil and plant evaluation in integrated production systems need to be refined for their use in experiments. This study purposed a sampling representativeness model to evaluate soil carbon and physiological parameters of marandu palisadegrass intercropped with double rows of eucalyptus in a silvopastoral system in southeastern Brazil. Four transects were delimited within the silvopastoral system and the soil was sampled at 0-5, 5-10, and 10-20 cm depths to evaluate two parameters of soil organic matter: total organic carbon (TOC) and soil microbial carbon (Cmic). We also evaluated three physiological parameters of marandu palisadegrass: stomatal conductance, transpiration rate, and photosynthetic rate. The sampling strategy was evaluated by the Hatheway and Modified Maximum Curvature (MMC) methods.We found that cultivation of the alley with forage grass and double rows of eucalyptus must be considered to ensure sampling representativeness in a silvopastoral system, once TOC and Cmic and physiological parameters showed variation within the integrated production system. The MMC method could be useful to evaluate silvopastoral systems for experiments and characterization of agricultural areas, as 11 soil samples are representative to evaluate Cmic and TOC, and 13 samples are enough to evaluate the physiological parameters in marandu palisadegrass. The Hatheway method could be applied to experiments that need higher accuracy with a reduction in the minimum difference to be detected between the treatments and a consequent increase in the number of samples to be collected.

RESUMOO Brasil está no primeiro lugar do ranking de maior número de equinos da América Latina, sendo também o terceiro do mundo. A Sulpirida é um D-2 antagonista do receptor da dopamina de baixo custo e em alta disponibilidade. Várias drogas e protocolos já foram testados em experimentos, a grande maioria teve como propósito obter um aumento no índice reprodutivo das éguas. A Sulpirida vem sendo utilizada há alguns anos com a finalidade de fazer com que seja precoce o retorno do ciclo estral quando em fase de transição considerando que a sua ação está ligada ao aumento da Prolactina e dos receptores gonadotróficos. Objetivou-se, através deste estudo, uma revisão narrativa da literatura científica, entre os anos de 2002 a 2016, através de busca eletrônica sobre a utilização da Sulpirida, nas seguintes bases de dados: Pub Med, PubAg e Google Acadêmico. A Sulpirida se fez eficaz na maioria dos trabalhos discutidos. A via de administração que obteve melhores resultados foi a via intramuscular, já que essa via apresenta maior biodisponibilidade quando comparada a via endovenosa, a via oral, entretanto, não foi discutida devido a baixa biodisponibilidade. Assim, conforme os estudos analisados, a Sulpirida auxilia e melhora o desenvolvimento folicular em éguas, aumentando sua eficiência reprodutiva.

USE OF SULPIRIDE IN FOLICULAR DEVELOPMENT IN MARES ABSTRACTBrazil ranks first in the ranking of the largest number of horses in Latin America, and is also the third in the world. Sulpiride is a low-cost, high-availability D-2 dopamine receptor antagonist. Several drugs and protocols have already been tested in experiments. Sulpiride has been used in a few years with the purpose of making the precycle or the return of the cycle the same when the transition phase is that its action is Recebido em 03/03/2017 e aprovado para publicação em 27/03/2017
