Use of by-products in liquid feeding
The use of by-products from the agri-food industry reduces feed costs. This study explores the nutritional value of eight potential by-products for liquid feeding.
Transition to diets without zinc oxide (2/2): additives
It is difficult for a single additive to mimic the effect of the addition of antibiotics or ZnO. This is why we need to combine groups of additives in water and feed, so they act both, as prevention and treatment.
Insects as an alternative raw material in pig feed
Products obtained from insects have a high proportion of crude protein: 40-44% in the case of the black soldier fly larvae, or up to 60% in the case of black fly larvae or in grasshoppers, and even reaching 70% in the case of silkworms.
How efficient are the current hyper-prolific lactating sows? (2/2)
In the previous paper, the effects of nutrient restriction and consequent catabolism during lactation on sow reproduction yield have been addressed. In the present paper, the efficiency of sows in using energy from feed and body mass is considered.
How efficient are the current hyper-prolific lactating sows? (1/2)
The study described here was designed to determine if the body tissue mobilization during lactation imposed by feed restriction could affect litter size and sow performance in the subsequent lactation.
Transition to diets without zinc oxide
With the restrictions on antimicrobial use as a preventive measure, a new era is born in the design of pre-weaning and grower diets. The transition to this new scenario must be approached in a comprehensive way.
Nutrition and immunity
Biological alterations in immune and intestinal systems occur immediately after weaning that affect subsequent pig growth and health.
Effects of feed processing and diet composition on the nutritional value
Pelleting and extrusion can potentially increase energy and nutrient digestibility of swine diets and their effects are affected by the diet composition.
