This study estimated the genetic parameters for reproductive and performance traits and determined which ones can be used as selection criteria for egg production in laying hens using the Bayesian inference. The data of 1894 animals from three generations of White Leghorn laying hens were analyzed for fertility (FERT), hatchability (HATC), and birth rate measurements at 60 weeks of age (BIRTH), body weight at 16 and 60 weeks of age (BW16 and BW60), age at sexual maturity (ASM), egg height/width ratio, weight, and density at 28, 36, and 40 weeks of age (RHW28, RHW36, RHW40, WEGG28, WEGG36, WEGG40, DENS28, DENS36, and DENS40, respectively) traits. The genetic parameters were estimated by the Bayesian inference method of multi-trait animal model. The model included the additive and residual genetic random effects and the fixed effects of generation. The a posteriori mean distributions of the heritability estimates for reproductive traits ranged from 0.14 ± 0.003 (HATC) to 0.22 ± 0.005 (FERT) and performance from 0.07 ± 0.001 (RHW28) to 0.42 ± 0.001 (WEGG40). The a posteriori mean distributions of the genetic correlation between reproductive traits ranged from 0.18 ± 0.026 (FERT and HACT) to 0.79 ± 0.007 (FERT and BIRTH) and those related to performance ranged from –0.49 ± 0.001 (WEGG36 and DENS36) to 0.75 ± 0.003 (DENS28 and DENS36). Reproductive and performance traits showed enough additive genetic variability to respond to selection, except for RHW28. This trait alone would have little impact on the genetic gain because environmental factors would have a higher impact compared to those from the additive genetic factors. Based on the results of this study, the selection applied on the BIRTH trait can be indicated to improve FERT and HATC of eggs. Furthermore, the use of the WEGG40 could improve egg quality in this population.

Abstract Background Patients with glioma are highly symptomatic and often have functional limitations from the time of diagnosis. Measuring health status may have value in determining impact of disease. This study provided a description of health status and utility scores in glioma patients throughout the illness trajectory using the EQ-5D (a functional measure of general health status). Furthermore, it evaluated the information provided by the MD Anderson Symptom Inventory-Brain Tumor (MDASI-BT; a measure of symptom burden and interference) in describing health-related quality of life as assessed by the EQ-5D. Methods Glioma patients completed the EQ-5D and MDASI-BT. Disease and clinical details were collected by medical record review. Linear regression evaluated whether MDASI-BT scores adequately predict patient health outcomes measured by the EQ-5D. Results The sample included 100 patients (65% male, 78% with a glioblastoma, median age 52 [range, 20–75], 56% in active treatment). Seventy-two percent of patients reported functional limitations in at least 1 area. Extreme cases reported inability to perform usual activities (8%) and significant anxiety/depression (5%). The MDASI-BT neurologic factor and activity-related interference (walking/activity/work) explained 52% of the variability in the EQ-5D in this patient population while adjusting for the effect of tumor grade, recurrence status, and performance status. Conclusions The majority of glioma patients reported at least 1 functional limitation on the EQ-5D. Over half of the variance in the EQ-5D was explained by the MDASI-BT, performance status, tumor grade, and recurrence status. The resultant model demonstrates the significant contribution of symptom burden on health status in glioma patients.

Breeding Techniques

Global experience related to increased pork production shows that breeding work has become an integral part of the technology, since it is impossible to further improve breeding and performance traits of animals without it and therefore the greater production of better quality pork. The paper presents the results of the breeding process arrangement for creation of F1 parental pig. Substantiation of breeding techniques when creating the final parental groups of sows (F1) with a high adaptive ability was based on complex methods to evaluate breeding animals, including traditional methods of domestic breeding and breeding indices. Evaluation of combination compatibility of breed-linear hybrids with the use of breeding indices during mating of parent initial forms allows to determine efficiency of using Yorkshire sows with Landrace boars, and Landrace sows with Yorkshire boars (final parental sows (F1)), which had significantly better reproductive indicators in comparison with BLW х BM genotype sows. Particularly efficient compatibility was recorded when selecting Yorkshire sows and Landrace boars. It was determined that in modern conditions an increase in the efficiency of breeding and pedigree work in pig breeding was based on the use of genetic methods, including: individual assessment of pedigree species according to the main breeding traits, evaluation of genome of each breeding animal, and use of breeding indices allowing to identify the true genetic potential of animals and predict performance traits of their offspring. The research relevance lies in using the innovative methodology for comprehensive assessment of combination compatibility of parental pairs, unified for pig husbandries and pig farms, which will make it possible to 10% accelerate the breeding process of forming the final parental forms of sows, ensure obtaining offspring with predictable reproductive, fattening and meat traits, and good adaptive ability.
