The Netherlands is faced with a surplus of manure and a serious concern about the effect of ammonia emissions on environmental acidification and the pollution of ground and surface water. Sows, weaners and slaughter pigs excrete 75%, 38% and 63% of the phosphorus consumed, and 76%, 46% and 67% of...

A review. Due to the competitive prices of liquid by-products feeding costs can be reduced by 10-17% when pigs are fed diets with liquid by-products. Moreover there is evidence for improved growth performance and pig health, and for a lower mortality rate. Of the liquid by-products, 70% have a high ...

The Technical Model for Pig Feeding (TMV) was developed in the Netherlands. This model predicts the influence of feed intake, feed composition, genotype, sex and climate on growth, body composition, marginal ratio (ratio of lipid/protein deposition per MJ of energy) and mineral excretion of healthy ...

A discussion. Because the gain to be expected from keeping a primiparous sow is always higher than that expected from a replacement gilt, the culling of these sows should be avoided. In practice, however, about 14% of primiparous sows are culled, and 50% of this culling is for reproductive reasons. ...

Several factors have an effect on growth rate and growth composition in pigs. Factors either alone or in combination affect production. Therefore models have been developed in order to predict growth rate and body composition under different environmental conditions. Models are useful tools in the...

During 1.5 years, 382 non-pregnant, pregnant and lactating sows were fed on diets containing 12% tapioca and 40% cereals, 10% tapioca, 40% cereals and 6% meat meal tankage or 35% tapioca with no cereals or animal protein. All diets contained metabolizable energy 12.17 MJ, 15.2% crude protein, 0.59% ...

The effect of nutrition on reproduction of gilts is reviewed briefly. Original experiments are described in which 720 Dutch Landrace gilts were fed from 12 until 38 weeks old on diets containing different amounts of protein, based on lysine content. A shortage of protein during rearing markedly...
