Abstract: Diets combining herbage and total mixed rations (TMR) are increasingly used in temperate regions for feeding ruminants,
but little information is available regarding the effects on nutrient intake and digestion of this feeding management in beef cattle.
The aim of this study was to determine the effects of combining TMR (10% CP and 13% ADF), and legume-based herbage
(14% CP and 27% ADF) on intake, nutrient digestion, ruminal fermentation, microbial N flow and glucose and nitrogen
metabolism in heifers. The experiment was a 3 × 3 Latin square design replicated three times; each period lasted 18 days
(10 adaptation days and 8 measurement days). Nine cross-bred (Aberdeen Angus × Hereford) heifers (214 ± 18 kg) fitted with
permanent rumen catheters and housed in individual metabolic cages were assigned to one of three treatments: 24 h access to
TMR ( T), 24 h access to herbage ( H) or combined diets with 18 h access to TMR and 6 h access to herbage ( T + H). Data were
evaluated using a mixed model. Animals fed T+H ( TMR 71% and herbage 29%) diets tended to have a higher dry matter intake
as a proportion of their BW than animals fed T. The T+ H diet did not change ruminal fermentation (pH, N?NH3 and volatile fatty
acids) or the N metabolism relative to the T diet, but increased the glucagon concentration and altered glucose metabolism.
Conversely, animals fed T +H had increased purine derivatives excretion, increased N use efficiency for microbial protein synthesis
and decreased plasma urea and urinary N excretion relative to animals fed H diet. The use of combined diets led to consumption
of nutrients similar to a TMR diet, without reducing nutrient use and could improve N utilization compared with the
herbage-only diet. MenosAbstract: Diets combining herbage and total mixed rations (TMR) are increasingly used in temperate regions for feeding ruminants,

ABSTRACT.
As an important cereal disease in humid and semi-humid areas, Fusarium head blight (FHB) has caused severe epidemics on wheat (Triticum aestivum L.) in different countries worldwide. By causing both yield loss and quality degradation, FHB presents a two-fold threat to farmers and consumers. Since the beginning of FHB research at the International Maize and Wheat Improvement Centre (CIMMYT) in the early 1980s, a large-scale FHB screening has been conducted to identify and incorporate new resistance genes into elite CIMMYT germplasm. Candidates of the 15th Fusarium head blight screening nursery (FHBSN) were derived from different CIMMYT wheat breeding programs and were tested for 3 years successively in El Batán, Mexico, before being included in the 15th FHBSN set. From 2010 to 2012, a set of 44 out of 2794 lines were gradually selected depending on their FHB indices, pedigree information, and phenological traits like plant height and days to heading. The performance of these lines varied across years under different disease pressure, but they all showed high level of resistance compared to the susceptible checks. In 2013, the nursery was again evaluated in El Batán, as well as in artificially inoculated field trials in Norway, Uruguay, the Netherlands, and Japan (2014), and in naturally infected experiments in Toluca, Mexico, and Canada. Although not all lines demonstrated strong resistance across environments, promising lines with good FHB resistance can still be identified in each location. The genotypes were haplotyped with PCR-based markers for ten loci on seven chromosomes associated with known FHB resistance, and the results suggested that 24 of the genotypes (55 %) carried the 4BS QTL as in Wuhan 1, which was the most frequent QTL in this nursery, and the 7A QTL as in T. dicoccoides was noticed in five (11 %) of the genotypes. The resistance QTLs on chromosomes 3B, 5A and 6B as in Sumai 3 and 3A as in T. dicoccoides were not detected in any of the genotypes denoting the uniqueness of these lines. Fifteen (34 %) of the genotypes may not carry any of the ten QTLs examined. The results provide valuable information that could be successfully utilized by breeders to select resistant parents for crosses since novel resistance sources were detected for better targeted crosses toward diversifying and/or pyramiding FHB resistance.
