AbstractProgenies of Oryza sativa cv. Nipponbare induced with 0.4% ethyl methane sulphonate (EMS) were screened for quality mutants and the preliminary quality mutant population was constructed in present experiment. A total of 2210 materials were first screened using near infrared reflectance spectroscopy (NIRS) from which 208 quality mutants were obtained for a second screening and then yielded 73 quality mutants including amylase content (AC), gel consistency (GC), gelatinization temperature (GT), protein content (PC), rapid viscosity analysis (RVA) parameters and amino acid contents. The screening yielded 11 PC mutants with a mutation frequency of 4.98‰, followed by 7 rice floury viscosity mutants (3.17‰), 5 AC mutants (2.26‰), 4 chalky mutants, GT and GC mutants (1.81‰), and 2 ASV mutants (0.9‰). The relative contents of 17 kinds of amino acid mutations, including 7 kinds for essential amino acids and 10 kinds for nonessential amino acids were identified. With the variation of 10% as the screening standard, mutants were obtained for lysine and leucine at 0.45‰ and for valine at 4.98‰, but no mutants were found for isoleucine, phenylalanine, threonine. For nonessential amino acids, mutants of glutamic (0.45‰), arginine (3.62‰), alanine (3.17‰), serine (0.45‰), glycine (0.45‰), tyrosine (1.81‰), proline (2.71‰), and histidine (0.45‰) were obtained, but none was found for aspartic, phenylalanine nor threonine. At 100% as the screening standard for methionine and cysteines, the mutation frequency of these two amino acid mutants were 0.9‰ and 4.98‰ respectively. Quality mutants in this preliminary library of rice could play important role in gene function and breeding of rice quality.

This paper presents a study of the effect of the feed additive «Abiotonic» on the indicators of egg and meat productivity when applied to laying hens. It was found that with the additional introduction of this additive into the standard diet of poultry, the content of nonessential amino acids in their meat is 10% higher compared to the same parameters in the meat of chickens of the control group, the content of partially nonessential amino acids is by 8,5%, and of irreplaceable amino acids is by 6,7%. In addition, in the meat of laying hens, which used the feed additive «Abiotonic», the content of selenium (Se) is 29,4% higher than in the meat of birds of the control group, and iron (Fe) – by 20%. The average daily gain in live weight of the birds in the experimental group was 3,6 g more than in the control hens. Microbiological research made it possible to establish that poultry meat, regardless of the introduction of the feed additive «Abiotonik», meets the established requirements and is safe for human consumption. «Abiotonic», in addition, significantly improves the egg production of birds. It was found that the weight of eggs with the introduction of this feed additive in the diet in addition to the compound feed increased by an average of 1,2 g, and the egg production increased by 23 eggs in 7 days.

Corn Ddgs

This study was conducted to determine apparent ileal amino acids digestibility (AIAAD) of diets with different levels of corn distiller’s dried grains with solubles (DDGS) and to determine AIAAD of corn DDGS by difference and regression methods in broiler chickens. One hundred and fifty 30-day-old male broiler chickens were used in the experiment. The corn DDGS were incorporated into basal diets at graded levels (0, 4, 8, 12, and 16%). All birds were killed at the age of 35 days and the contents of the lower half of the ileum were collected. AIAAD was calculated using chromic oxide as the indigestible marker. For AIAAD of DDGS determination, difference and regression methods were used. AIAAD of Lys (78.6%) and Met (91.3%) were the significantly highest in the diet without DDGS in comparison with other diets (P < 0.01). AIAAD of the rest of essential and nonessential amino acids were the lowest in the diet with 8% of DDGS in comparison with the diets with 0 or 16% of DDGS (P < 0.01). The apparent ileal crude protein digestibility was also the lowest in the diet with 8% (61.8%) of DDGS (P < 0.01). The highest differences in AIAAD of DDGS determined by the difference method and in the diet without DDGS (basal diet) determined by the regression methods were found in Lys and Met. There were very low differences between DDGS and basal diet in AIAAD of nonessential amino acids, except Ala and Asp. These results show that higher levels of DDGS decrease AIAAD.

Abstract The following nutritional criteria were evaluated for their usefulness in predicting outcome in a prospective study of 66 randomly selected hospitalized patients with a variety of diagnoses: total protein, albumin, and transferrin concentrations in serum, creatinine height index, weight height index, phenylalanine/tyrosine ratio (Phe/Tyr), concentration of branched-chain amino acids in serum, and ratio of essential to nonessential amino acids in serum. The cases were followed from admission to discharge, and were classified into the following three groups: 43 "well"; 14 with "complications" but recovered; and nine "dead". Statistical analysis (Scheffe's s-test) demonstrated the means of "well" and "dead" groups to be different for total protein, albumin, transferrin, and Phe/Tyr. In individual patients the nutritional criteria, even for those with fatal outcome, were poor indicators of outcome. These nutritional criteria are useful in identifying hospitalized groups that are at maximum risk (i.e., death), but are much less useful for individual patients.

Amino acid excretion was studied in young, healthy men during summer, fall and winter months in a southwestern U. S. location. Both untimed and timed urine samples were employed. The amino acids determined were alanine, arginine, cysteine, glutamic acid, glutamine, glycine, histidine, lysine, methyl histidine, serine, threonine and valine. Supplemental determinations included urine volume, creatinine, uric acid, urea, sodium and potassium. Using untimed urine samples and expressing values as ratios with creatinine, significant seasonal variation was found for alanine, arginine, cysteine, glutamic acid, glycine, lysine and serine.
