The objective of this study was to investigate antimicrobial activity, during the storage period, of animal feed and any effects on in vitro rumen digestion by supplementing different levels (5.55, 11.1, and 22.2 g/kg) of freeze dried citrus peel (FDCP) to the feed compared to untreated feed and feed treated with an antifungal agent (AA) at 0.05 g/kg. In a preservation test, feed supplemented w...

This study was performed with growing chicken (14 to 56 d of age) to evaluate the effects of feeding them a barley or triticale-based diet. The treatments were corn diet (1) as a control, hulless barley diet with (5) or without (2) enzyme, triticale diet with (6) or without (3) enzyme and hulled barley diet with (7) or without (4) a commercial β-glucanase enzyme. In a digestibility trial, 21 ma...

It's expected that the Brazilian production of industrialized feed for horses reach 2 million tons by the year 2020. Feed processing consists of physical, chemical or biological modifications that are made in the feed. These modifications can increase the availability of nutrients for horses and/or preserve the quality of these nutrients in the raw material. The objective of this review was to ...

Cross-linking of lignin to arabinoxylan by ferulates limits in vitro rumen digestibility of grass cell walls. The effect of ferulate cross-linking on dry matter intake (DMI), milk production, and in vivo digestibility was investigated in ad libitum and restricted-intake digestion trials with lambs, and in a dairy cow performance trial using the low-ferulate sfe corn mutant. Silages of 5 inbred ...

Protein is the major component for shrimp feeds and must be nutritionally appropriate and readily digestible. In vitro protein digestibility of feeds and feed ingredients, and their inhibitory effect on the digestive proteases of juvenile Farfantepenaeus paulensis were examined. The analysis included animal (four types of fish meal, meat meal and blood meal) and plant (soybean meal and wheat fl...

This study aimed to evaluate the nutrient digestibility of growing rabbits fed diets with different levels of either Leucaena leucocephala (LLM) or Moringa oleifera (MOLM) leaf meals and also to compare total collection and TiO2 marker methods for estimating digestibility. A total of 30 California growing rabbits (1.81±0.19 kg live weight on average) were randomly distributed into five experime...
