Erosion and economic valuation of nutritional supplementation in cultivated soil with burned and non- burned sugarcane in Campos dos Goytacazes – RJ | Author : Niraldo José Ponciano, Ana Carolina Guzzo Monteiro, Sérgio Gomes Tosto, Paulo Marcelo de Souza, Cláudio Roberto Marciano | Abstract | Full Text | Abstract :The efficiency of Brazil in the production of sugar and ethanol is unquestionable, however, the challenges still remain for
the management of the burning of the straw in the pre-harvest of sugarcane, which has generated negative externalities.
Water erosion is one of the most aggressive forms of environmental degradation and which has caused huge losses.
This
work was carried out in the municipality of Campos dos Goytacazes, RJ, Brazil, in order to estimate soil erosion losses in an
area planted with sugarcane under two types of crop management. The Universal Soil Loss Equation (EUPS) was used to
obtain the erosion rates and the Replacement Cost Method (MCR) to carry out the economic valuation of the ecosystem
service.
The results show that the rate of soil loss from sugarcane burned was four times greater when compared to the rate
for sugarcane harvested raw for both areas studied. The replacement cost of lost nutrients in the cultivation of sugarcane
under harvesting system with previous burning was R$6.73 and R$15.91 per hectare of lowland and coastal tableland,
respectively, while in the sugarcane harvesting unburned system the cost per hectare was R$ 1.66 for the lowland and R$
7.56 per hectare for the coastal tableland.
It is concluded that the crop management system influences environmentally the
preservation of soil fertility and the cost of fertilization of the crop. |

| Monitoring of soybean grains (Glycine max L. Merril) stored in metal silos | Author : Leticia Almeida Sorano, Rienni de Paula Queiroz, Guilherme Araújo Brustolin | Abstract | Full Text | Abstract :The main post-harvest concern is with the processing and storage, which plays a fundamental role, since they seek to
guarantee the quality of the product that comes from the field. The storage process is the activity that stores and conserves
the grains, aiming to guarantee the quality of the product regardless of the time it is kept in storage (BROOKER, 1992 apud
LIMA, 2013). The objective of this work is to monitor the classification, temperature and humidity of soybeans at the
Coopergrãos Cooperative, located in Nova Andradina – MS, and how these variables interfere with the quality and longevity
of grains stored in silos. The temperatures were obtained through thermometry performed with the Thermo Collector MOD.
V5 FOCKINK, where weekly temperatures during the months of May, June and July were monitored for each cable and its
respective sensors. During this monitoring period, two samples of soybean grains were collected on different days in June to
gauge moisture. The samples were withdrawn with the interval of 20 minutes to representatively express the material
present in the silo, and were collected at the end of the conveyor belt. There was no proliferation of microorganisms or
insect pests, where the grain mass did not present favorable humidity and the temperature was below the optimum for its
proliferation. In the classification, we found the total number of defects above the allowed for soybean, but it was framed as
Out of Type which does not prevent the sale of grains for other uses in the commercialization. |

A 4 x 6 factorial design was used, with six evaluation times. Continuous activities (feeding, rumination, other activities and leisure) and punctual (salt intake, water intake, urination and defecation) were evaluated, as well as food behavior variables. From the inclusion level of 10% of the RUC, an effect (P <0.05) was observed for rumination, other activities and leisure time. The period of the day had an influence on all the behavioral variables studied independently of the inclusion level of wet brewery residue, being the 20% level with the best results. |
| Current scenario of milk active in the rural properties of Presidente Figueiredo, Amazonas, Brazil | Author : Ytaiara Lima Pereira, Mariana Silva Albuquerque, Francisco Martins de Castro, Luiz Aldiney Alves de Oliveira, Paulo Cesar Gonçalves de Azevedo Filho, Jomel Francisco dos Santos | Abstract | Full Text | Abstract :The objective was to characterize the current dairy cattle production of Presidente Figueiredo - AM. In the period from 2017 to 2018, 11 active dairy farms were visited. 57.4% of the producers stated that they only performed one milking daily, justifying this practice due to the low productivity of the animals, on average 40 liters / day. 81.82% of the interviewees know the IFAM, however, all the interviewees have not yet participated in any action promoted by the institute. Dairy farming in Presidente Figueiredo is characterized by low production and low technology. Most of the producers are new to the activity and require technical instruction to improve sanitary, reproductive, nutritional and milking management to leverage better dairy production results. |
| Serum biochemistry and carcass of broilers, in natural heat conditions, supplemented with organic zinc and vitamin E | Author : Jackelline C Ost Lopes, Jefferson D Martins Ferreira, Agustinho V de Figueirêdo, João B Lopes, Sidclay F Maia, Mabell N Ribeiro, Vânia de S L Aguiar | Abstract | Full Text | Abstract :The objective of this study was to evaluate the effect of organic zinc and vitamin E on diets for broilers exposed to natural cyclic heat conditions, from 1 to 21 days of age, on carcass and cut yield, skin resistance and serum biochemistry. A total of 600 male and female Ross 308 chicks were used and distributed in a completely randomized design in a factorial scheme. The treatments consisted on inclusion of organic zinc (0 and 120 mg/kg) in association with vitamin E (0, 300 and 600 mg/kg) in the birds diets. The carcass yield was higher with 120 mg of organic zinc/kg when compared to the treatment without the mineral. Serum triglycerides decreased with 300 mg and 600 mg of vitamin E supplementation. There was interaction between the levels of zinc and vitamin E promoting the fall of blood albumin levels. Organic zinc provides higher carcass yield and vitamin E, associated or not with zinc, improves the serum biochemistry of broiler chickens under natural cyclical heat conditions up to 21 days of age. |
| Lipids for dairy cows – performance and milk composition | Author : Dhemerson da Silva Gonçalves, Rogério Mendes Murta, Camila Marques Oliveira, Hélio Oliveira Neves, Antônio Eustáquio Filho, Thiago Carlos e Silva | Abstract | Full Text | Abstract :The objective of this revision is to study and compare the effects of the use of different levels and lipid sources in the
production and composition of milk in dairy cows. Using lipids aims to increase the productive performance per animal and
the energy concentration of the diet to supply the energy deficit at the beginning of lactation and to obtain greater efficiency
of milk production. Several sources are used, such as lump of cotton, soybeans, sunflower, vegetable oils and calcium salts
of long-chain fatty acids. Recent work suggests higher percentage of fat in the diet ranging from 8-9%. The use of fats in the
diet at the beginning of lactation brings benefits in the performance of animals. |
