Barley Genotypes

Twenty-three barley genotypes were grown in field plots and the seed-yield components and seed composition were investigated. Ten malting and feed cultivars and waxy endosperm selection lines had the standard concentration of lysine in their seed protein. The other genotypes were five different natural or induced high-lysine mutants and/or selection lines developed from them. High-lysine lines were lower yielding than the most productive normal lysine cultivars because of a decrease in weight per seed, accompanied by a reduced content of the carbohydrates extractable with dimethyl sulfoxide. Ris� mutant no. 7 was exceptional in having fewer seeds per unit area and a normal carbohydrate content. Within the group of lys 3 homozygotes derived from Ris� no. 1508, the higher yielding lines had more seeds per unit area, higher concentrations of extractable carbohydrates, and lower concentrations of crude protein. Similar trends with yield also occurred among the lines homozygous for the lys gene from Hiproly. The yields of the most productive lys and lys 3 homozygotes approached that of Clipper, the leading Australian malting cultivar, but were 25% lower than that of the most productive feed barley, Cutter. The other mutants, Ris� no. 7, Ris� no. 29 and Clipper 500, were lower yielding than the better lys and lys 3 selections. The possibilities for improving the yield and energy content of the latter two high-lysine types by selection are discussed.

Abstract Two experiments were conducted to test the hypothesis that the standardized total tract digestibility (STTD) of P and digestible energy (DE) and metabolizable energy (ME) in a new variety of high-lysine sorghum is not different from values obtained in conventional sorghum varieties or in corn. In experiment 1, 48 barrows (18.63 ± 0.89 kg) were housed individually in metabolism crates and randomly allotted to 1 of 8 diets. Diets were based on high-lysine sorghum, red sorghum, white sorghum, or corn as the sole source of P and these diets either contained no microbial phytase or 500 units/kg of phytase. Feces were collected using the marker to marker approach with 5-d adaptation and 4-d collection periods. Data were analyzed by ANOVA using the Mixed Procedure of SAS. Results indicated that phytase supplementation improved (P ≤ 0.05) STTD of P in all ingredients, but the STTD of P in high-lysine sorghum was not different from the STTD of P in other grains (Table 1). In experiment 2, 32 barrows (18.54 ± 0.77 kg) were housed individually in metabolism crates and randomly allotted to 1 of 4 diets. Diets contained high-lysine sorghum, red sorghum, white sorghum, or corn as the only energy-containing ingredient. Feces and urine samples were collected using the marker to marker approach with 5-d adaptation and 4-d collection periods. Data were analyzed as explained for Exp. 1. The ATTD of gross energy in high-lysine sorghum was less (P ≤ 0.05) than in corn, but the DE and ME in high-lysine sorghum was not different from corn. In conclusion, supplementation of phytase improved STTD of P in cereal grains, and values for STTD of P, as well as for DE and ME in high-lysine sorghum, were not different from corn, which indicates that high-lysine sorghum can replace corn in swine diets.

Three experiments were conducted to evaluate the nutritive value of four new high-lysine barley mutants, their parent variety Sultan and the high-lysine variety Lysimax. The problem of low yield, frequently encountered in previous studies with high-lysine barley, was overcome for Lysimax in this study; cv. Lysimax yielded 4% more than cv. Sultan. The highest lysine levels: 4.87, 4.75 and 3.96 g 16 g−1 N occurred in cv. Lysimax and Risø mutants (RM) 609 and 1405 compared with 3.48, 3.43 and 3.55 g 16 g−1 N in cv. Sultan and RM 1242 and 1385, respectively. Compared with cv. Sultan, the glutamic acid levels in RM 1405 and 609 and cv. Lysimax were 7.2, 25.8 and 31.3% lower, respectively. Likewise, the proline levels in RM 1405 and 609 and cv. Lysimax were 10.3, 32.2 and 37.9% lower, respectively. In the first experiment, with rats, the barleys were the sole protein sources in the diets. In the second experiment, with young pigs, only cv. Lysimax and RM 1405 were used (700 g kg−1 diet) in two starter diets. In the third experiment, the diets fed to the pigs in the second experiment were diluted with an N-free mixture and fed to rats. In the first experiment, biological values (BV) of cv. Lysimax and RM 609 (89.0% and 91.0%, respectively) were significantly greater than that of cv. Sultan (73.9%). Compared with Sultan true protein digestiblities (TD) and energy digestibility (ED) were slightly lower (P < 0.05), at most 3.6 and 4.2 percentage units, in RM 609, 1385 and 1405 and cv. Lysimax, respectively. In the second experiment with young pigs, the apparent BV of the Lysimax diet (84.1%) was higher (P < 0.05) than that of the RM 1405 diet (77.4%). The ED was 2.1 percentage units lower (P < 0.05) for the Lysimax diet than for the RM 1405 diet. In the third experiment with rats, the BV for the Lysimax diet was higher (P < 0.05) than for the RM 1405 diets, TD and ED were similar (P > 0.05). It is concluded that the development of high-lysine barley varieties is beneficial for meeting the requirements of indispensable amino acids for monogastric animals. Moreover, N excretion into the environment is substantially reduced due to a reduction in the prolamin protein fraction which is rich in glutamic acid and proline.
