“…Organic and sustainable milk production is gaining more and more interests. However, organic milk production still constitutes too small to be an important segment of dairy production [66]. That is why education and advertisement should play an important role in delivering information about the benefits of organic dairy products.…”

Factors Shaping Cow’s Milk Production in the EU

The milk market in the European Union (EU) is adjusting rapidly to the removal of dairy quotas. The most important changes include increased milk yield per cow, increased total milk production, decreased number of cows, and the decreased milk consumption. The main aim of the paper is to examine the milk production changes in the EU. We investigated the dynamics of changes in farm milk production during the period from 1998–2017 in the EU. Moreover, we investigated the impact of the removal of quotas on the production of milk on farms in the EU countries for the period from 2015–2017. Milk production in the EU increased from 151 million tons in 1998 to 165 million tons in 2017 (a 10% increase). A multi-variate regression model was to test which explanatory variables have an impact on milk production in the EU. The most important factors were a gross domestic product, final household consumption expenditure (current prices, million euro), and population (number).

“…Even though the dominant species in US pastures are not native (Sanderson et al, 2012), pastures can increase farm and landscape habitat diversity, especially in areas with extensive row‐crop production (Egan and Mortensen, 2012; Russo et al, 2013). Pastures can also be leveraged to add value to livestock products, particularly in contrast with confinement operations (Hafla et al, 2013).…”

Agriculture in the United States must respond to escalating demands for productivity and efficiency, as well as pressures to improve its stewardship of natural resources. Growing global population and changing diets, combined with a greater societal awareness of agriculture's role in delivering ecosystem services beyond food, feed, fiber, and energy production, require a comprehensive perspective on where and how US agriculture can be sustainably intensified, that is, made more productive without exacerbating local and off‐site environmental concerns. The USDA's Long‐Term Agroecosystem Research (LTAR) network is composed of 18 locations distributed across the contiguous United States working together to integrate national and local agricultural priorities and advance the sustainable intensification of US agriculture. We explore here the concept of sustainable intensification as a framework for defining strategies to enhance production, environmental, and rural prosperity outcomes from agricultural systems. We also elucidate the diversity of factors that have shaped the past and present conditions of cropland, rangeland, and pastureland agroecosystems represented by the LTAR network and identify priorities for research in the areas of production, resource conservation and environmental quality, and rural prosperity. Ultimately, integrated long‐term research on sustainable intensification at the national scale is critical to developing practices and programs that can anticipate and address challenges before they become crises. Core Ideas The LTAR network was established to enhance the sustainability of US agriculture. The LTAR “common experiment” compares business as usual with aspirational management. LTAR sites contribute research observations to the network's database. LTAR network research will support sustainable intensification strategies.

“…However, a comparison of NEFA concentration should consider the productive system to which cows are subject. In particular, organic dairy cows have lower overall milk production and a higher variation of milk yield between individuals [32]. In the same idea, NEFA concentrations in the study cows resembles that of cows identified as low producing individuals in some reports [33].…”

Background Negative energy balance during the transition period is a concern for both conventional and certified organic dairy systems. During early lactation, supplemental strategies are used to cope with nutrient deficiencies that are associated with impaired health, production, and reproduction. As organic certified dairies in the United States face restricted access to dietary supplements, the evaluation of products especially formulated for organic production is needed. Our objective was to assess the effect of supplementing 0.45 kg/d of an organic rumen-protected fat (RPF) on health, metabolic status, and productive and reproductive performance of organic certified Holstein cows from 1 to 150 days in milk (DIM). Two-hundred and two cows were enrolled in a randomized blocked controlled trial conducted from January to July, 2017 in a certified organic dairy located in Northern Colorado (USA). Two groups were randomly assigned to be individually supplemented with organic RPF (ORG; n = 100) or control pellets (CON; n = 102) once per day, in addition to the total mixed ration (TMR). Outcomes of interest included disease occurrence, culling, mortality, serum concentration of glucose and non-esterified fatty acids (NEFA), milk yield (kg/d) and milk components, resumption of cyclicity, time-to-first artificial insemination (AI), conception at first AI, and conception within 150 DIM. Results A significant effect for the inclusion of RPF was found in daily milk yield; RPF supplemented cows had greater milk yield (1.6 kg/d) compared to CON cows up to 150 DIM (P = 0.03). During grazing, multiparous (MP) ORG cows had greater milk yield compared to MP CON cows, whereas no effect was found in primiparous (PP) cows. Health outcomes, serum metabolite concentrations, and reproductive performance were not affected by the inclusion of RPF. Body condition loss was smaller in the ORG group up to 80 DIM; however, there was no effect on body condition during the grazing season and in the overall study period. Conclusions These results indicate that supplementation of RPF increased daily milk yield and prevented body condition loss during transition. However, RPF supplementation did not affect health, serum metabolite concentration, milk components, and reproductive outcomes.
