Sowing and flowering delays can be an efficient strategy to improve coexistence of genetically modified and conventional Maize
The coexistence between genetically modified (GM) and non-GM maize (Zea mays L.) fields is subjected to regulation in several countries. A strategy to reduce cross-pollination from GM to non-GM fields was evaluated, on the basis of reducing the flowering coincidence by sowing at separate times. The trial included narrow plots in which transgenic maize was sown before, simultaneously, and after ...

Agronomic performance of different pea cultivars under various sowing periods and contrasting soil structures
Yield variability of spring pea (Pisum sativum L.) in farmers' fields is mainly due to soil compaction at sowing and abiotic stresses during the reproductive period. Winter peas flower earlier, and thus should be less sensitive to abiotic stress at the end of the cycle, but because of their sensitivity to frost they must be sown late in autumn when soils are very wet. Pea breeders are working on ...

Seasonal infertility: the cause, the cost and can you prevent it from happening?
Still summer and already warning for the upcoming seasonal infertility?! A good understanding of what causes seasonal infertility or the so-called after-summer dip can help in preventing and limiting the negative consequences. What is seasonal infertility? It is the natural phenomenon occurring in September and October when healthy sows spontaneously return to service about 4 weeks after ...

Emergence of polymer-coated corn and soybean influenced by tillage and sowing date
No tillage often delays soil warming and drying, thus sowing too early in the spring may compromise seed viability due to prolonged exposure to cold and wet soil in the northern Corn Belt. Coating seed with a temperature-activated polymer may circumvent the adverse effects of exposing seeds to cold and wet soil. Germination and emergence of noncoated and polymer-coated corn (Zea mays L.) and ...

Characterization of selected nutrients and bacteria from anaerobic swine manure lagoons on sow, nursery, and finisher farms in the Mid-South USA
Received for publication October 31, 2008. Swine (Sus scrofa domestica) production in the Mid-South USA comprises sow, nursery, and finisher farms. A 2007 packing plant closure started a regional shift from finisher to sow and nursery farms. Changes in manure stored in lagoons and land-applied as fertilizer were expected but were unknown because nutrient and bacterial levels had not been ...

Swine Production Tips and Feeding Strategies to Dodge Temperature Variations : Beating the Heat in Farrowing!
The effects of heat stress on lactating sows has been studied by several research institutions worldwide. We can look at primiparous (first parity) or multi-parous sows but the results are similar (Williams, 2009) For this discussion, let us look at farrowing room environment conditions of 68°F (desired) vs. 77°F (hot). The period that should be most scrutinized is the ambient ...

Scrutinize herd retention by rethinking gilt development
Not everyone will agree with my arguments in this article. However, I’m tired of hearing complaints about current sow mortality rates and general agreement that additional research is needed in gilt development; yet remain disappointed in the lack of tangible, practical strategies that producers can take home and implement at the ‘slat level’ to make meaningful changes in their ...

Farrowing feeding for sow production: What to consider to improve profitability and productivity
Feeding a Farrowing Sow: What Should we Consider? From feeder costs to feed palatability, here are some of the hot topics to think about when you are choosing the right sow feeding system for your farrowing rooms. Farrowing Feeding Methods Farrowing sows play an essential role in pig production since sow and litter performance can influence the swine industry’s next outcomes. Considering ...

A higher birthweight due to preventive actions!
The majority of pig breeders knows the yearly production cycle. A productive first half of the year turning into a period with possible heat stress followed by seasonal infertility in September to end with less viable piglets in October and November. Breaking this cycle completely is impossible due to the fact that some of the causes are deeply wired into the genetic code of the pig. Although, ...

A Guide to Optimizing Sow Feed Intake
Creating the optimal environment for farrowing sows can help to minimize the challenges producers face when it comes to maintaining proper body condition and raising healthy piglets, as sow well-being will always be a constant concern within our industry. Improvements to sow feeding are a clear opportunity for improvement to body condition, overall health, increased productivity and overall herd ...

The Importance of Feed Intake in Lactation on a Sow’s Productivity
Feeding Systems in Farrowing: The Questions of a Producer Alain and Donald Lefebvre are the owners of Ferme Aldo. In 1999, they decided to do a research on feed intake at their farm. Although this was some years ago, the results are still relevant to swine production today. The findings of the study, generated using Gestal feeders, from the ALDO farm were conclusive: maximizing feed intake ...

Electronic sow feeding system
In 2013, the company Börde Porc GmbH & Co. KG set up a modern sow management farm in one of the most fertile plains of Germany, the so-called "Magdeburg Börde". The new houses provide space for around 2,400 productive sows and 600 gilts. Once again, Big Dutchman was allowed to prove its capability by providing the required sow equipment. To date, Börde Porc's location ...

Feed Blending in Farrowing: An Optimal Feeding Solution
The Next Frontier in Lactating Sow Nutrition Advances in research regarding the nutrient requirements of the lactating sow have academics and producers alike realizing the need for feeding precisely to the needs of the herd, which can vary considerably from published values. For example, in the Swine NRC (Nutrient Requirements of Swine, published by National Research Council in 2012) gilt and ...

Model-based approach to quantify production potentials of summer maize and spring maize in the north China plain
The North China Plain (NCP) belongs to the major maize (Zea mays L.) growing areas in China. Maize yields have increased steadily since the 1980s, but in recent years average yields have stabilized around 5000 kg ha–1. The objective of this study was to quantify the production potential of summer and spring maize in the NCP. For this purpose the CERES-Maize model was calibrated and validated. The ...

Stability of Cytoplasmic male sterility in maize under different environmental conditions
Cytoplasmic male sterility (CMS) is a maternally transmitted trait, whereby a plant is unable to produce viable pollen. Studies have revealed that this trait is a tool for enabling efficient and reliable coexistence between genetically modified (GM) and non-GM cultivation by biocontainment of GM maize (Zea mays L.) pollen. Maize has three types of male-sterile cytoplasm (T, S, and C), the ...

Discovering the Links Between Boar Management and Fertility
A late 2019 report on boar fertility indicated that “Boars, like sows, must be treated with compassion and dignity, to maintain a positive and economic well-being for the animal and producer.” This is something many UK pig farmers are well aware of, and yet it pays to lean in and listen to a bit more about the latest discoveries of links between boar management and their fertility. ...

Lighting for Farrowing Shed - Case Study
Each pig production phase has different demands that require different lamps in different lighting intensities. The light should suit the phase in pig production and the type of pig house. Take the farrowing house as an example, offering optimal 200-300lx light intensity on the ground and 8-16 light hours can promote piglets and sow lactation, resulting in higher weaning weights. Also an ...
