Nonanatomical reduction of femoral neck fractures in young patients treated with femoral neck system: a retrospective cohort study.

Purpose: Negative buttress reduction should be avoided in the treatment of femoral neck fractures (FNFs) using conventional fixation. As the femoral neck system (FNS) has been recently developed and utilized widely to treat FNFs, the association of reduction quality with postoperative complications and clinical function has not been clarified. The purpose of this study was to evaluate the clinical effect of nonanatomical reduction in young patients with FNFs treated with FNS.

Estimation of genetic correlations of two key feed efficiency traits with production traits in male Hu sheep.

Increased body growth and feed efficiency are important for breeding due to expensive feed costs.

Whole Genome Sequencing Analysis to Identify Candidate Genes Associated With the rib eye Muscle Area in Hu Sheep.

In sheep meat production, the rib eye area is an important index to evaluate carcass traits. However, conventional breeding programs have led to slow genetic progression in rib eye muscle area. Operationalizing molecular marker assisted breeding is an optimized breeding method that might improve this situation.

The growth traits are economically important traits in sheep. Improving growth rates will increase the profitability of producers. The aim of this study was to identify alleles of (encoding T-cell surface glycoprotein CD8 beta chain) that are aberrantly expressed in different tissues and to assess the effects and associations of its different genotypes on weight and size traits in sheep.

Polymorphisms in the ovine gene associated with blood physiological indices.

This study aimed to analyze the effects of polymorphisms in on blood physiological indices of 1065 sheep. The coefficients of variation of the red blood cell count (RBC), hemoglobin concentration (HGB), mean platelet volume (MPV), mean erythrocyte hemoglobin content (MCH), and red blood cell distribution-coefficient of variation (RDW-CV) were greater than 10%, and there was a very significant correlation between the main indices such as RBC, white blood cell, and platelet count (PLT) and most other indices ( 0.01).

Detecting Single Nucleotide Polymorphisms in and and Elucidating Their Association with Sheep Growth Traits.

Herein we detected single nucleotide polymorphisms in and by DNA sequencing and the KASPar technology and analyzed their association with sheep growth traits. Two synonymous mutations, g.1826 C > T and g.

Polymorphism and expression of the HMGA1 gene and association with tail fat deposition in Hu sheep.

Hu sheep is an excellent short fat-tailed breed in China. Fat deposition in Hu sheep tail affects carcass quality and consumes a lot of energy, leading to an increase in feed cost. The objective of this study was to analyze the effects of polymorphism on tail fat weight in Hu sheep.

Ovine ELOVL5 and FASN genes polymorphisms and their correlations with sheep tail fat deposition.

Reducing tail fat deposition can increase the economic value of a carcass and improve feed efficiency. This study aimed to explore ELOVL5 and FASN polymorphisms associated with tail fat deposition and their expression levels of sheep. Association analysis showed that ELOVL5 synonymous mutation g.

Expression of ovine CTNNA3 and CAP2 genes and their association with growth traits.

Growth traits is a critical economic trait for animal husbandry. In this study, the SNPs of CTNNA3 and CAP2 genes were investigated to check whether they are associated with growth traits (body weight, body height, body length and chest circumference) in Hu sheep. The result of the association analysis indicated that the mutation in CTNNA3 (g.

Effect of feed efficiency on growth performance, body composition, and fat deposition in growing Hu lambs.

The present study aimed to investigate the relationship between growth performance, body composition, and fat deposition factors, and feed efficiency in growing lambs. We measured average daily feed intake (ADFI) and body weight (BW) from 653 Hu sheep that were fed a pellet diet. The residual feed intake (RFI) not significantly genetic and phenotypic correlated with the metabolic body weight (MBW) and average daily gain (ADG), but it was significantly genetic and phenotypic correlated with ADFI and the feed conversion ratio (FCR) ( < 0.

Whole-genome resequencing identified candidate genes associated with the number of ribs in Hu sheep.

The number of ribs is an important economic trait in the sheep industry when the sheep are raised for mutton. However, in sheep, the genetic mechanisms regulating rib number are poorly understood. In the present study, we aimed to identify important candidate genes that affect the increase in rib number in sheep.
