Abstract: The efficiency of an alternative freezing protocol for goat embryos of different morphology and quality was tested. Fifty-eight embryos on Day 6-7 stage were transferred as fresh or after freeze-thawing (n=29/group). For freezing, embryos were placed into 1.5M ethylene-glycol solution for 10min. During this time, they were loaded in the central part of 0.25mL straw, separated by air bubble from columns containing PBS/BSA 0.4% plus 20% BFS. Straws were then frozen using a freezing machine from 20ºC to ?6ºC at a cooling rate of 3ºC/min, stabilization for 15min (seeding after 5min), from ?6 C to ?32ºC at 0.6 C/min,and plunged into liquid nitrogen. Frozen embryos were thawed for 30s at 37ºC in a water bath. Embryos subjected to fresh transfer were maintained in holding medium (37ºC). Fresh and frozen-thawed embryos were transferred at day 7 post-estrus to 30 recipients. Kidding and kid born rates were similar (P> 0.05), respectively, for recipients receiving fresh (66.7% or 10/15; 55.2% or 16/29) or frozen-thawed (60% or 9/15; 51.7% or 15/29) embryos. The cryopreservation of goat embryos using slow-freezing protocol and 1.5MEG resulted in similar efficiency rates of fresh embryos. [Congelação de embriões caprinos em diferentes estádios de desenvolvimento e qualidade utilizando etileno glicol e taxa de resfriamento lenta]. Resumo: Este estudo testou a eficiência de protocolo alternativo de criopreservação de embriões caprinos de diferentes qualidades morfológicas. Foram utilizados 58 embriões, coletados entre o sexto e o sétimo dia do ciclo estral (n=29/grupo). Embriões congelados passaram por solução 1,5M etilenoglicol por 10min e foram aspirados durante esse tempo para parte central de palheta 0,25mL, separada por bolhas de ar de colunas contendo PBS 0,4% BSA e 20% SFB. As palhetas foram congeladas em máquina de congelação de 20ºC a -6ºC, com taxa de resfriamento de 3ºC/min, estabilização por 15min (seeding após 5min), -6ºC a -32ºC a 0,6ºC/min, e imersas em nitrogênio líquido. Os embriões foram descongelados por 30s a 37ºC, em água. Embriões frescos foram mantidos em solução de manutenção (37ºC). Embriões frescos e congelados/descongelados foram transferidos para 30 receptoras no sétimo dia do ciclo estral. A taxa de partos e a de crias nascidas (respectivamente) foram similares (P>0,05) para receptoras recebendo embriões frescos (66,7% ou 10/15; 55,2% ou 16/29) ou congelados/descongelados (60,0% ou 9/15; 51,7% ou 15/29). O protocolo de criopreservação de embriões utilizado no presente estudo resultou em índices de eficiência semelhantes aos de embriões frescos.

Aims: Aim was to analyze the economic viability of an integrated crop-livestock-forest (ICLF) system area, in the municipality of Pindaré-Mirim, State of Maranhão, Brazil, using the consortium of maize (Zea mays L.), forage species Urochloa brizantha cv. Marandu and Eucalyptus (Eucalyptus urograndis). Study Design: Case study. Place and Duration of Study: The work was developed in a Technological Reference Unit of ICLF of Embrapa Cocais, located in the municipality of Pindaré-Mirim - Maranhão, Brazil, between January 2016 and July 2017 and The experimental area was 3 ha, divided into three subareas: Treatment I - single corn planting; Treatment II - Barreirão system; and Treatment III - Santa Fé system. Methods: In this work, the method of operational costs was used. The following economic performance measures were calculated: Gross income (GI), Gross margin (GM), Net margin (NM), Profit, Leveling point (LP) and Rates of return (RR). The economic indicators calculated were: Net Present Value (NPV), Internal Rate of Return (IRR) and Benefit-Cost Ratio (RBC). The data collected from the costs and revenues of each treatment were tabulated and treated with the help of Microsoft Office Excel. Results: All the treatments presented a profit, being the Barreirão System the one that had better results, presenting P of 163 bags of maize ha-1, GI of US$ 1974, profit of US$ 780, LP in 99 bags, of 60 kg, of corn ha-1 and RR of 65.33%. Treatments I and III presented, respectively, P of 135 and 143 bags of maize ha-1, GI of US$ 1635 and US$ 1732, profit of US$ 504 and US$ 543, LP in 94 and 99 bags of corn ha-1 and RR of 44.63% and 45.67%. Conclusion: The results obtained reinforce the importance of studying the economic feasibility of ICLF system to provide the investor with the conditions for better decision making.
