Amino Acid Requirements

SummaryA trial was conducted, using 12 mature thoroughbred horses in a cross-over design, to compare the protein and amino acid digestibility of dry lucerne chaff (LC) against a controlled fermented lucerne (CFL) product (HNF Fiber®; Fiber Fresh Feeds Ltd, Reporoa, New Zealand). Crude protein levels were higher in CFL compared to LC, and when individual amino acids were analysed, the majority (88%) of these were also higher. Crude protein digestibility was significantly (18%) higher in CFL diets (P < 0.001) compared to LC. Significant differences (P < 0.05) were seen in individual amino acid digestibility in favour of the CFL diet for lysine (24%) and methionine (30%), as well as threonine, histidine, tyrosine, leucine, isoleucine, valine, alanine, proline, serine and aspartamine. Although amino acid requirements in horses are still poorly defined, the higher availability of amino acids in CFL compared to LC should be taken into account when formulating horse diets including these feedstuffs.

Breeding Programs

The common bean (Phaseolus vulgaris L.) represents a sustainable and affordable source of protein, namely, to populations with vegetarian dietary habits. Despite the national germplasm genetic diversity, little is known about the Portuguese accessions’ nutritional and protein quality, leading to their underuse in breeding programs. To fill this gap, a representative collection (106 accessions) was cropped under two contrasting environments (traditional versus heat stress) and evaluated in terms of nutritional quality by near-infrared spectroscopy. Protein quality was assessed, under the stressful environment, considering the individual amino acid contents and the activity of trypsin inhibitors through mass spectrometry (LC-MS/MS) and spectrophotometry, respectively. On top of strong genotypic control, the nutritional composition (protein, fat, fiber, moisture and ash) was also highly influenced by the environment and by genotype × environment interaction, with a clear nutritional quality ranking change for the accessions in heat stress conditions. Classified into three clusters, the accessions from the cluster with the highest individual amino acid and protein contents also showed higher trypsin inhibitor activity (TIA). Since different levels of TIA had no translation into contrasting protein digestibility, breeders focusing on common beans’ protein quality improvement, especially under challenging warming climate conditions, may take advantage of this group of accessions.
