Olive cake by-product improves growth performance and carcass traits in growing finishing pigs

Low inclusion levels of olive cake by-product at growing-finishing diets may improves growth performance and provide healthy fatty acid profile in fat tissues.

Abstract

Soybean meal can be partly replaced by field pea in weanling diets

Increasing inclusion of field pea reduces dietary crude protein digestibility but without negative impact on performance.

Abstract

Survey of serum vitamin D status across stages of swine production and evaluation of supplemental bulk vitamin D premixes

These results revealed that commercial swine may be deficient in serum vitamin D at varying times of the year, and feed-supplement concentrations may vary.

Abstract

Consequences of different dietary energy sources during follicular development on subsequent fertility of cyclic gilts

These results suggest that it is possible to manipulate dietary insulin response in cyclic gilts and, thus, improve reproductive efficiency when feeding starch as the main energy source during the late luteal and follicular phases of the cycle.

Abstract

Effect of feeding on hormones related with feed intake in reproductive sows

Insulin, acylated ghrelin and cortisol could be used as biomarkers to detect situations resulting in a poor energy balance in order to improve handling programs.

Abstract

Mussel meal as a protein source for growing pigs

Mussel meal can be used as protein sources in pig diets maintaining performance and meat quality.

Abstract

Dietary inclusion of extruded B. juncea canola expeller-pressed cake in growing-finishing pigs

The use of B. juncea in pig diets reduces feed intake and performance during de growing-finishing period.

Abstract

Tryptophan requirement of pregnant sows

Tryptophan requirement of pregnant sows increases from 1.7 g/d in early to 2.6 g/d in late pregnancy.

Abstract

Dietary net energy content has a differential effect on carcass performance depending on gender

Higher NE content should be recommended for females slaughtered at 120kg of BW.

Abstract

Colostrum yield is influenced by feeding strategy and sow body condition

Sows with high peripartal feeding show highest colostrum yield and better colostrum composition.

Abstract

Esterified acid oils as fat sources for growing pig diets

The esterified palm acid oils high in MAG and DAG increase saturated fatty acid deposition.

Home

Abstract

New ZnO presentations can be used at lower concentrations in weanling diets

Low concentrations of commercial potentiated ZnO is effective in against of ETEC-challenged weaning pigs.

Abstract

State-of-the-art on use of insects as animal feed

The information synthesized is expected to open new avenues for a large scale use of insect products as animal feed.

Abstract

Dietary crude protein reduction and AA supplementation affects tissue fatty acid composition in pigs

Fatty acid composition of pork lean and fat may be altered by reducing dietary CP and supplementing AA.

Abstract

Effect of feed restriction on performance and nutrient metabolism in pigs co-infected with M. hyo and SIV

Altogether, these results indicate that modifying feeding practices could help to prepare animals to overcome an influenza infection.

Abstract

Anterior teats secrete higher volumes of colostrum than the posterior

Anterior teats appear to contain more IgA and IgG than the posterior ones in sows.

Abstract

The risks of high inclusion of wheat-corn DGGS not be completely alleviated by formulating diets on the basis of NE and SID AA systems

High inclusion of wheat-corn DDGS reduces growth performance and ATTD of energy in growing pigs.
