This document describes the experience in the control and eradication tasks of invasive weeds carried out in the crops of Catalonia since 2005, from its management point of view. The results allow to affirm that is a complex and not immediate process. Since avoiding the arrival of new plants is very difficult and expensive rapid detection and rapid action on introduced weeds are essential for success. This fact highlights the importance of having a good network of technicians all around the agricultural areas that transfer the information when a problem is detected; also having regulations that allow immediate action is essential. The invasion risk evaluation and the viability of weed control increases the likelihood of success in the eradication process and helps optimizing resources. The biological characters that have been observed as most important for the success of a new introduction are described. The criteria to Llenes et al. ITEA-Inf. Tec. Econ. Agrar.

本文件从管理的角度描述了自2005年以来在加泰罗尼亚农作物中进行的入侵杂草控制和根除任务的经验。研究结果证实，这是一个复杂而非立竿见影的过程。由于避免新植物的到来是非常困难和昂贵的，快速检测和快速行动对引进的杂草是成功的关键。这一事实突出了在农业地区周围建立一个由技术人员组成的良好网络的重要性，当发现问题时，技术人员可以传递信息;此外，制定允许立即采取行动的法规也很重要。入侵风险评估和杂草控制的可行性增加了根除过程中成功的可能性，并有助于优化资源。描述了已观察到的对新引种成功最重要的生物学特性。以Llenes等人为标准。ITEA-Inf。侦探。经济学。Agrar。(en prensa)， Vol. xx: 1-20 1 *作者通讯段:FALTA Cita del artículo: Llenes JM, Consola S, Montull JM, Taberner A (en prensa)。经验和控制的malas hierbas invasoras en Cataluña desde el punto de vista de su gestión。修订Bibliografica。ITEA-Información taca Económica Agraria。第xx卷:YY-YY。https://doi.org/10.12706/itea.2020.015 2 Llenes等。ITEA-Inf。侦探。经济学。Agrar。(en prensa)，第xx卷:1-20

The aim of this study was to evaluate the “chorizo gallego” fatty acid profile elaborated with lean and fat from pigs fed with a liquid diet including milk whey compared to pigs fed with a commercial solid feeding. The monounsaturated fatty acids were the major fatty acids. Individually, the fatty acids with the highest proportions were oleic (42 % of total fatty acids), palmitic (24 %), stearic (12-13 %), linoleic (8-11 %), vaccenic (3 %), palmitoleic (2.5 %) and myristic. The statistical analysis showed that 14 out of 22 fatty acids presented significant differences between both diets. The inclusion of whey in the diet González-Torres et al. ITEA-Inf. Tec. Econ.

Iberian pig production in the free-range system is limited by acorn production. In order to provide an alternative, the use of the Gevuina hazelnut has been proposed. Pigs were split up in two groups (n = 6 per group), one of those was provided with commercial feed (according to appetite) and the other was given a commercial feed and 2 kg of hazelnut/ animal and day from 126,6 ± 4,7 kg of weight until slaughter. The hazelnut analysis revealed they have a great proportion of fat (44 %), with a high amount of monounsaturated fatty acids (MUFA) (93.94 %), of which the main fatty acids where palmitoleic acid (29.99 %) and oleic acid (50.60 %). The C18:1n-9 concentration increased in the hazelnut group, as time increased (P = 0.0001), this led to a greater decrease of C16:0 concentration (P = 0.001) in the hazelnut group than in the other group.

自由放养系统中的伊比利亚猪产量受到橡子产量的限制。为了提供一种替代方案，建议使用吉瓦纳榛子。将猪分为两组(每组n = 6头)，其中一组根据食欲饲喂商品饲料，另一组饲喂商品饲料和2 kg榛子，从体重126(6±4.7)kg起至屠宰。分析结果表明，榛子含有大量的脂肪(44%)，含有大量的单不饱和脂肪酸(MUFA)(93.94%)，其中主要的脂肪酸是棕榈油酸(29.99%)和油酸(50.60%)。榛子组C18:1n-9浓度随着时间的增加而增加(P = 0.0001)，这导致榛子组C16:0浓度的下降幅度大于其他组(P = 0.001)。虽然，榛子组的C18:1n-9的最终水平没有增加serrano等人。ITEA-Inf。侦探。经济学。Agrar。(书面报告)，第xx卷:1-15 1 *作者段落通信:anarey@vet.ucm.es Cita del artículo: Serrano MP, Ruiz-de Dulanto N, Rey AI(书面报告)。新替代方案alimentación萨尔瓦多·伊布海姆:使用la avellana Gevuína。ITEA-Información taca Económica Agraria。Vol. 20: 1-15。https://doi.org/10.12706/itea.2020.009 2 Serrano等。ITEA-Inf。侦探。经济学。Agrar。(原封不动)，第二十卷:1-15

Amaranthus palmeri has become one of the most important weed species in the agriculture of the United States of America. During the last few years, there have been reports indicating that this species is invading agroecosystems in other countries and regions, including Spain. The success and weediness of this weed is due to its high reproductive potential, high growth rate, and fast evolution of resistance to herbicides of multiple mechanisms of action. Furthermore, this species has high adaptability that enables invasion of ecosystems different than its center of origin, resulting from its dioecious reproduction, high genetic diversity, and its potential for hybridizing with other Amaranthus species. Due to its weediness, when there are A. palmeri established populations, it is critical to develop integrated mana gement plans that focus on eliminating seed production. In countries or regions where this species is starting to invade, it is recommended that not only regulatory authorities, but also the agricultural sector as a whole, implement aggressive actions to prevent the establishment and dispersion, preferably aiming to eradicate this weed from those places where it is first detected.

The aim of this study was to evaluate the prediction of body weight (BW) of the native Mexican guajolote (NMG) from morphometric measurements (MM) and morphological indices using classification and regression tree analysis (CART). Measures were taken of 244 NMG from the states of Puebla, Chiapas and Campeche. The BW and ten MM were collected, and three morphological indices were estimemated: massiveness (MAS), stockiness (STK) and body condition (CON). The descriptive statistics and Pearson’s correlation (r) of the variables were analyzed and a regression tree was constructed using the CART method. Coefficients of variation <20% were obtained in the MM, an MAS of 13.50%, STK of 111.12% and the CON of 16.81%. Correlations between BW and MM ranged from moderate to high (r = 0.35 to r = 0.91; P < 0.0001). The CON was the variable with the best score (100%) in the normalized importance analysis, followed by MAS (79.2%) and thoracic perimeter (52.8%). The optimal regression tree diagram formed a total of 13 nodes, of which 7 were terminal nodes, demonstrating that the CON is sufficient to predict the BW of NMG. This study allowed to define a prediction model with an observed explained variance of 86.4% and included the CON, body height and wing width, which can be applied by producers to reliably predict body weight of NMG
