Efeito do período pós-parto sobre a taxa de prenhez de vacas de corte submetidas à IATF (Inseminação Artificial em Tempo Fixo)

This work aimed to evaluate the influence of postpartum period (precocious - of 28 to 44 days and late - of 45 to 90 days) on the bovine pregnancy rate using fixed-time AI. For that, 678 cows were divided in two groups: precocious group (G-P, n=151) and late group (G-T, n=527). The animals received CIDR® + 2 mL of estradiol benzoate (BE) in the day zero (D0). After eight days (D8) the dispositive was removed and both groups received 2.5mL PGF2α, concurrent with PGF2α injection, they received either 1.5mL of eCG or temporary calf removal (RTB). In the next day (D9), the cows received 1 mL de BE and 24 hours later, the fixed-time AI was performed with Nelore bovine semen. The calves were returned to their mothers. The pregnancy rate was not different between the groups (p>0.05), G-P=40% and G-T=48%. The results indicate that females with less than 45 days of postpartum are able to hormone protocol of fixed-time IA.

Sobrevivência de enxertos de Eucalyptus com metodologia adaptada

One of the important techniques to assist a tree improvement program is the grafting, which is used for the propagation of selected trees. The objective of this study was to evaluate the survival rate using a modified method of lateral grafting on Eucalyptus dunnii, Eucalyptus urophylla and a hybrid of Eucalyptus urophylla x Eucalyptus grandis. The work was conducted by the research teams of Eucatex and Palmasola companies, in September of 2011, and 589 grafts were made. The survival rate of the grafts was evaluated 180 days after grafting. Survival grafts rates were: 74% for E. dunnii, 55% for E. urophylla and 62% for the hybrid E. urophylla x E. grandis. These survival rates were higher than those currently obtained by the conventional method of eucalypt grafting. Thus, the method seems promising to assist in forest tree improvement programs, but further studies are still necessary to refine this grafting approach.

Polinização controlada em eucaliptos nas empresas florestais brasileiras

Controlled pollination is an important tool in a forest genetic improvement program, which permits to choose parents and make specific crosses maximizing gains and providing superior genotypes in less time than conventional pollination. To verify the needs of the forest companies regarding the conduction of controlled pollination orchards in the breeding program, a specific questionnaire was sent in September 2011 to companies associated to IPEF. The objective of the questionnaire was to collect basic information about the current situation of controlled pollination orchards and check the main difficulties and demands related. It was found that use of the controlled pollination orchard has begun to be used by companies in the Brazilian forest sector just a few years ago and is considered to be very important in breeding programs in order to shorten the time to obtain new genotypes; but there is still need of crucial information regarding the management of these orchards. The main demands are: Basic concepts of flowering induction; homogeneity of flowering; hormonal induction and alternative techniques for flowering; relationship between management and genotypes used; variations in the flowering of different genotypes; management of the orchard in the different phenological phases; process of grafting typesand interaction between graft and rootstock, irrigation systems; species identification and flowering map.

Análise energética do milho em sistema de plantio direto, no assenta-mento rural da fazenda pirituba, Itaberá/SP

The aim of this work was to proceed, from the energetic point of view, an analysis of a corn agroecosystem, on the direct planting, located at Pirituba II rural workers placement project, Área III, city of Itaberá/SP. The energetic analysis mesured all operations, together with its fisical demands, the inputs and produced grains, classifying them within their respective flux, based on the definition of energy inputs and outputs, converting them into energetic equivalents and, so, determining the energetic matrix of de agroecosystem. The caloric index used were cultural efficiency and cultural liquid energy. The results showed the dependence of the studied systems on the chemical energy sources, from fertilizers (39,49%), agrotoxics (27,74%), and fossile energy of diesel (24,94%). The energetic values of the direct and indirect energy showed a very big difference between them, what means that the energy sources used in the system are not balanced. The cultural efficiency found was 12,86 and cultural liquid energy got to 115.025,92 MJ x ha-1. Later on, obtained data was compared to already existing data in Bueno (2002), who researched conventional planting system. The cultural inputs of both systems were energeticaly different: 9.696,97 MJ x ha-1 (direct planting), e 8.783,78 MJ x ha-1 (convencional planting). The outputs had very different results: 124.722,89 e 79.118,38 MJ x ha-1, respectively. So, we had much more cultural liquid energy on the studied system: 115.025,92 MJ x ha-1, compared to convencional system: 70.334,60 MJ x ha-1. The energectic loss of nitrogened fertilizers contributed for the high energetic loss of both energetic studied matrices. There are few contribution from biological energy source in both systems.
