“…Even though pregnancy rates found in the present experiment seemed to be low, they are consistent with pregnancy rates found at early lactation (90 days postpartum) in DP cows at the same experimental station (Aguilar-Pérez et al 2009a, 2009b. In DP systems in Mexico, the interval between parturitions births exceeds 500 days, mainly caused by the extensive postpartum anoestrus period, originated by the negative effects exerted by suckling and the feeding of cows with low-quality pastures (Rojo-Rubio et al 2009). Low pregnancy rates have been reported in cows grazing Leucaena (Jones et al 1989;Hammond 1995) associated with the ingestion of the nonprotein amino acid mimosine and the effect of its metabolites 3,4-DHP and 2,3-DHP.…”

The aim of the study was to evaluate the productive and reproductive performance of dual-purpose (DP) cows with a restricted concentrate allowance and access to a forage association of Leucaena (Leucaena leucocephala) and Stargrass (Cynodon nlemfuensis). Twenty-four multiparous Holstein × Zebu cows were used during the first 98 days postpartum. .97 ± 0.6, TL = 11.9 0.6) with a similar composition (P > 0.05). There were no differences (P > 0.05) between treatments for changes in live weight (CT −29.6 kg, LT −33.3 kg) and body condition (CT −1.3, LT −1.4, in a 1-9 scale). Population of ovarian follicles per cow was similar between treatments throughout the experiment. Pregnancy rate was 33% for CT and 25% for LT, with no significant differences (P > 0.05). Grazing an association of Leucaena and Stargrass can replace part of the concentrate without detrimental effects on production and reproduction in DP cows.

“…Dual Purpose (DP) livestock system has been widely described by Espinosa & Wiggins (2003), Bartl et al (2009) and Rojo-Rubio et al (2009). In American tropic regions, it is located from Mexico (Hernández- Morales et al, 2013;Albarran-Portillo et al, 2015;Salas-Reyes et al, 2015) to northern Brazil (García-Martínez et al, 2016), including Venezuela (Urdaneta et al, 2013), Colombia (Cortés-Mora et al, 2014), Ecuador (Torres et al, 2015), Costa Rica and Peru (Bartl et al, 2009;Lentes et al, 2010).…”

Mixed crop-livestock farms are widely spread in different tropical regions in the world; they contribute to food security, rural development, sustainability and poverty alleviation. The effect of scale on performance of dual purpose (DP) cattle farms was evaluated in two Mexican ecological zones: dry (DT) and wet tropics (WT). In 2011, a questionnaire of 184 items distributed into technical and social characteristics was applied to a representative sample of 3,285 farms with 50 or less cows (0.97%). The farms were classified into three groups according to their dimension: very small (1-9 cows), small (10-19 cows) and medium (20-50 cows). A general linear model (GLM) with two factors and their interactions was applied. Significant effects in dimension and ecological zone were found as well as seven interactions between both factors (p<0.05). Native pastures were used in all farms for grazing. However, small farms' herds frequently grazed on cultivated pastures and on crop residues (p<0.05). Medium farms showed the highest grazing surface, but in the WT silage and green fodder were used while in the DT dry fodders were used (p<0.001). The interactions between factors showed a bigger specialization in milk production in DT farms, whereas WT farms were more specialized in meat production. The mixed crop-livestock system in tropic region requires an increase in herd size according to farm's own productive structure, which is strongly influenced by the ecological zone. The systems would improve with the active participation of smallholders to identify and achieve best practices, higher technological adoption level and with an effective support from public and private Institutions.Additional keywords: marginalization; subsistence; dual purpose; tropics; resilience.

“…The prevailing climatic conditions for the new settlements led to altered production objectives (i.e., less milk and more meat). Even with current technology and knowledge, raising livestock for the purposes of milk production is still difficult in tropical areas (González-Sedano et al 2010;Rojo-Rubio et al 2009). The livestock introduced by the Spaniards had to endure most parasitic problems naturally as there were no medicinal drugs available for treatment and the local flora had never been used previously to treat imported farm animals for such parasites.…”

Issues in Agroecology – Present Status and Future Prospectus

Parasites are one of the most important threats to domesticated livestock worldwide. For several decades, their control has been based only on therapeutic interventions using chemical products at fixed intervals throughout the year. Results have demonstrated that dependence on these chemical products, as a single form of control, is not economically and ecologically sustainable. The problem has been augmented due to the emergence of endoparasite and ectoparasite populations resistant and multiresistant to the primary families of chemical products used to control them. Yet, these chemicals continue to be overused as the primary method for parasite control. Even more, their toxicity to animals, environmental contamination, and economic cost are of increasing concern. This limited approach to parasite control has environmental consequences with likely negative impacts to human and animal health. For example, most endectocides used to control parasites (endoparasites and ectoparasites) in domesticated animals are eliminated in the milk produced by females. Thus, there is strong concern regarding human consumption of dairy products containing such chemicals. Currently, market demands focus on healthy livestock production with emphases on the high standards in animal health and welfare based on quality production practices. The sustainable production of domesticated livestock needs strong changes, such as considering agroecologically oriented as well as novel approaches for parasite control. Thus, the use of existing drugs should be more strategically implemented and combined with other nonchemical alternatives for ruminant livestock. New strategies for controlling parasites in ruminant livestock should begin with the premise of not eliminating or eradicating parasitic organisms, but instead basing actions on economic thresholds (similar to IPM strategies for agricultural crops). In this review, we discuss the problem and current situation regarding parasites and their control using ranching operation methods. We discuss regions where the problem of chemical resistance is of strong concern and include the ecological and socioeconomic effects of parasite control (or lack therefore). We present information about novel approaches such as improving the nutritional status of the host and biological control methods for integration with domestic livestock in order to decrease the use of and reliance on chemical products.
