New feeding strategies to reduce polluting gas emissions from manure
Incorporating fibrous by-products in the feed reduces the emission of ammonium from manure and nitrous oxide in agricultural fields
Prevention of worker health and safety problems in Pork Production
After reviewing some of the main hazards for pork producers in previous articles, this article is devoted to practical measures describing how to reduce risks of illnesses and injuries from those hazards.
Safety around manure handling
Liquid manure in deep anaerobic storage, contains sulfur (from amino acids in feed, manure or in water) which certain bacteria (anaerobes) use as a substitute for oxygen. They produce H2S as an end product, which is toxic to living tissue, by stopping the energy supplying reactions in the tissue cells.
Manure foaming issues
Foaming in swine manure is not a recent issue. The unusual aspect of foaming manure today is the significant increase in foaming events.
PRRSv stability in manure and implications for transport biosecurity
About 50% of the vehicles used for transporting pigs in the United States are not washed between loads, so this article evaluates the ability of heating treatments to inactivate PRRSv present in manure-contaminated environments.
Computer simulation to find the best feeding strategy
Production of pig meat worldwide exceeds that of any other meat. Traditionally, linear programming is used to generate minimum cost diets that to meet the pig nutrient requirements. Of greater importance to the pig producer than least cost diets is the maximisation of gross margin (per pig place or per pig place per year).
Fattening: Cleanliness and feed
This new test has to do with the correct feed and levels of hygiene in the pens.
Dimension and design of the farrowing unit
The Danish pig producers’ research organisation has tested a number of different designs. They recommend pen dimensions of 2.7x1.8 m to accommodate modern prolific breeds.
Water quality in pigs
Water is the most essential nutrient to livestock nutrition and must be considered as much as possible. It should be drinkable, it should not contain harmful substances and should be readily available for the animals concerned.
Phosphorus requirements of growing-finishing pigs reared in a commercial environment
A challenge in animal production today is to raise livestock within new environmental rules and regulations. Although most states in the United States regulate swine waste application based on N concentration, more are changing to P-based regulations.
Use of plant extracts in swine
The swine production industry has a growing interest in the use of essential oils. Essential oils are products of complex origin. They have antimicrobial and antioxidant effects, they stimulate appetite and intestinal secretions and they are even immunostimulants.
Material for the manipulation activities of the pig: better to face the problem than ignore it!
Pigs must have permanent access to a sufficient quantity of material to enable proper investigation and manipulation activities, such as straw, hay, wood, sawdust, mushroom compost, peat ...
What causes coughing in pigs?
Any factor that irritates or inflames the respiratory system will elicit the physiological response of either sneezing or coughing or both. Although alarming and indicative of disease, coughing is at least a sign that normal physiological responses are taking place and should not in isolation be necessarily seen as a bad thing. We may have sudden or generalized outbreaks of coughing as well as a constant coughing in pig groups. There are infectious pathogenic agents that are normally associated with coughing or laboured breathing in pigs such as Actinobacillus, Bordetella, Haemophilus, Pasteurella Streptococcus, Mycoplasma, SIV, PRRSV or PCV2.
