Introduction: The article presents the results of a long-term study of quantitative traits in winter triticale varieties and accessions grown in the soil/climatic conditions of the central region of Belarus using conventional and intensive cultivation technologies. The effects of the intensification level on the yield, performance constituents and triticale grain quality are described. Purpose: to assess the variability of quantitative traits in winter triticale grown by conventional and intensive cultivation technologies in Belarus. Material and methods: Winter hexaploid triticale varieties and promising accessions grown by traditional and intensive technologies in a competitive variety trial nursery were studied. The plot area was 10 m2; the replication number was three; the design was randomized; the seeding rate was 4.5 million viable seeds per hectare; the observation period was in 2011-2020. Upon intensive cultivation, additional doses of nitrogen fertilizers, trace elements (Cu, Mn), growth regulators and fungicides were applied. The contents of crude protein, gluten and starch in grain were determined by near-infrared spectroscopy Results and discussion: During the observation period, the average yield from the winter triticale accessions in the competitive variety trial nursery was on 69.3 dt/ha and 77.8 dt/ha upon the application of traditional and intensive cultivation technologies, respectively. The additional factors of intensification increased the yield by 8.5 dt/ha or by 12.3 %. The constituents of the main spike performance as well as contents of crude protein and gluten in winter triticale grain also grew. Strengthening of intensification of the cultivation technology didn’t significantly affect the test weight, 1000-grain weight or crude protein content. Conclusions. The use of additional methods of intensification was demonstrated to change the absolute values of the winter triticale indicators, to have no key impact on the level of their environmental of genotypic variability. The test weight and crude protein content were the most stable traits, while the gluten content and yield – the least stable ones, as their values were determined by both varietal specificity and environmental factors

Higher Fatty Acids

The availability of dietary Mg for five lactating cows decreased in proportion to the amount of animal fat added to their winter ration. Previous workers have reported that increasing crude protein content of the herbage is associated with decreasing availability of Mg for the cow, and that the content of higher fatty acids in grass and hay increases with increasing crude protein content. It was suggested that nitrogen fertilizers increase the fat content of the herbage, thereby reducing the availability of Mg. (Abstract retrieved from CAB Abstracts by CABI’s permission)

Mischkolz, J. M., Schellenberg, M. P. and Lamb, E. G. 2013. Early productivity and crude protein content of establishing forage swards composed of combinations of native grass and legume species in mixed-grassland ecoregions. Can. J. Plant Sci. 93: 445–454. We evaluated the early establishment productivity of forage swards of native, perennial, cool and warm season grasses, and legumes as they have the potential to provide non-invasive, productive, and drought resistant rangelands. Seven species with agronomic potential and a broad native geographic distribution were selected for testing including: nodding brome [Bromus anomalus (Coult.)], blue bunch wheatgrass [Pseudoregneria spicata (Pursh)], western wheatgrass [Pascopyrum smithii (Rydb.)], side oats grama [Bouteloua curtipendula (Michx.)], little blue stem [Schizachyrium scoparium (Michx.)], purple prairie clover [Dalea purpurea (Vent.)], and white prairie clover [Dalea candida (Willd.)]. Forage swards, including all seven monocultures, 21 two-species mixtures and a mixture with all species, were planted in two sites, Saskatoon and Swift Current, Saskatchewan. Western wheatgrass (WWG) had the highest overall plant density and the strongest effect on the forage yield of the forage swards; however, productivity and crude protein content were not reduced when other species were also included in the forage sward. Dalea spp. did not establish as well as the other species, but had the highest crude protein concentrations. This work provides insight into forage sward development at the establishment stage; additional work is required to determine long-term species impacts for well established forage swards.

Dietary Crude Protein

AbstractThis study investigated the effects of 100 g/kg increments of crude protein (approx. 250 (P25) to 550 (P55) g/kg of crude protein) in paired iso-energetic diets on the growth performance of the juvenile Australian short-finned eel (1·83 (s.e. 0·01) g average wet weight). The highest growth response was obtained with treatment P45 followed by P35, P55 and P25. It appeared that food efficiency ratio (FER) increased with increasing crude protein content in low energy diets (treatments P25 and P35). However, 100 g/kg increase in dietary crude protein content (from 450 to 550 kg crude protein per kg diet) in high energy diets resulted in lower FER for treatment P55 than for the treatment P45. The protein efficiency ratio (PER, %) was higher in low protein:low energy diets (treatments P25 and P35) than that of high protein:high energy diets (treatments P45 and P55). The protein productive values (PPV, %) for treatments followed a similar trend to PER in this experiment. The lowest PPV was obtained by the treatment P55 and it was significantly different from that of the other three treatments. A proportional increase in dietary crude protein content in paired iso-energetic diets did not significantly change the whole body protein content. However, a small increase in whole body protein content with increasing dietary crude protein in each group was detected. In conclusion, the present study showed protein sparing effects of lipids and carbohydrates in the diets of the short-finned eel. Further studies specifically investigating the effects of dietary carbohydrate to lipid ratios at different protein levels would improve diet formulation and reduce nutrient impact in intensive recirculation systems.
