Background: GnRH-1 mainly exists in hypothalamus and it is vital to gonad development and sexual maturity of animals. This study mainly analyzed the association between GnRH-1 polymorphism and carcass traits of quails, Research conclusions can provide references for breeding of new species of quail.Methods: From 2018 to 2019, 31 female samples of Chinese Yellow quail, beijingbai quail and Korean quail were collected in Luolong District, Luoyang City, Henan Province, China.SNP mutation sites of GnRH-1 gene were investigated in China yellow quail, Beijing white quail and Korean quail through PCR amplification and DNA sequencing technologys. Moreover, correlation analysis between polymorphism sites of GnRH-1 gene and carcass traits of quail was performed. Result: According to research results, a total of 14 SNP mutation sites of GnRH-1 were detected in China yellow quail, Beijing white quail and Korean quail, which were C71T, C108T, C168T, C178T, A184G, C206T, A209C, C215T, A252G, A279T, C281T, C293G, C339T and C458T. For A209C and C281T, only 2 genotypes were detected in China yellow quail and Beijing white quail, while for the remaining 12 SNP mutation sites, 3 genotypes were detected in three quail species. Correlation analysis showed that A209C, A279T, C281T and C339T were significantly correlated with liver weight (P less than 0.05), A209C, C281T and C339T were significantly correlated with dressing percentage (P less than 0.05), C215T and A279T were significantly correlated with breast muscle weight(whole) (P less than 0.05), A209C was significantly correlated with body weight, dressed carcass weight and whole net carcass weight (P less than 0.05).

Genetic And Phenotypic Correlations

Abstract The aim of this study was to estimate coefficients of heritability as well as genetic and phenotypic correlations among body weight and carcass traits. The dataset contained records of 387 birds from the second crossbred generation. The following traits were recorded: body weight (BW) at 11 weeks, carcass weight (CW), breast muscle weight including superficial and deep muscle (BMW), leg muscle weight including thigh and shank (LMW), wings weight (WW), skin with subcutaneous fat weight (SW), abdominal fat weight (AFW), skeleton with the back muscle and inedible elements (SBM), and liver weight (LW). Estimates of variance components were obtained by the average information - REML algorithm in the ASReml package. Very high slaughter yield (74.90%) was obtained. Generally, the coefficients of heritability were high. The highest one of 0.75 was estimated for body weight at 11 weeks. High coefficients of h2 were estimated for breast muscle weight (0.69), wings weight (0.70), carcass weight (0.65), skin with subcutaneous fat weight (0.57) and skeleton with the back muscle (0.58), whereas h2 of liver weight was 0.29. Both phenotypic and genetic relationships between the recorded traits were usually positive. Generally, it seems that the crossbreeding scheme can be perceived as a suitable proposal for the breeding practice.

Criterion Variables

In this study, canonical correlation analysis was applied to estimate the relationship between body measurements and carcass traits of 28 male cross bred rabbits of about 12 weeks of age, reared under semi intensive system. Four body measurements, pre-slaughter weight (PSW) , body length (BL), chest circumference (CC), and ear length (EL) as predictor variable while dressing percentage ( DP) , hot carcass weight (HCW) and cold carcass weight (CCW) as criterion variables. Pre-slaughter weight and body length had significant (P<0.001) simple correlation coefficients with the carcass traits except for dressing percentage. The three canonical variate pairs ranged between .99 to .42 and only the first pair was significant (P<0.001). From the analysis pre-slaughter weight and body length can be regarded as the main factors as live measurement traits, while dressing percentage did not have pronounced effect on the emerged criterion variables.

The Relationship

This study examined the relationship of iodine value (IV) with carcass weight, fat depth, muscle depth, and predicted lean yield from 37,488 pork carcasses. Five IV categories were formed, which were defined as low (<64.99), medium-low (65.00–69.99), medium (70.00–74.99), medium-high (75.00–79.99), and high (>80.00). Correlation analysis indicated IV was weakly correlated (r ≤ 0.26; P < 0.05) with all carcass traits, however the categorical analysis revealed that greater IV was associated with heavier weight and leaner carcasses. Segregation systems of pork carcasses based on IV should consider the relationships of IV with other carcass parameters before implementation.

The Relationship

In this study, canonical correlation analysis was applied to layer data to estimate the relationships of egg production with age at sexual maturity, body weight and egg weight. For this purpose, it was designed to evaluate the relationship between two sets of variables of laying hens: egg numbers at three different periods as the first set of variables (Y) and age at sexual maturity, body weight, egg weight as the second set of variables (X) by using canonical correlation analysis. Estimated canonical correlations between the first and the second pair of canonical variates were significant (P &lt; 0.01). Canonical weights and loadings from canonical correlation analysis indicated that age at sexual maturity had the largest contribution as compared with body weight and egg weight to variation of the number of egg productions at three different periods. &nbsp;

In 1986, 247 ganders of the Selected Chinese and Selected Synthetic strains, and Large Embden and Small Embden- sired strain crosses at the Greenbelt farm of the Centre for Food and Animal Research in Ottawa, Canada, were evaluated. The Chinese and Synthetic (developed from the Pilgrim, Chinese and Hungarian) strains had been selected for four generations to increase egg production over a 24-wk laying period and body weight at 16 wk of age, and simultaneously decrease total fat content. Two Embden strains, Large and Small, denoting contrasting body sizes, had been imported from the United States of America for potential use in crossbreeding as terminal sire strains. Strains and strain crosses were ranked from high to low, for body weights at 9 and 16 wk of age, liveweight at slaughter and eviscerated carcass weight. Large Embden × Selected Chinese were largest followed by Small Embden × Selected Synthetic and Small Embden × Selected Chinese strain crosses, in turn followed by the Selected Chinese and Selected Synthetic strains. Small Embden-sired crosses were not significantly different except for body weight at 9 wk of age and eviscerated carcass weight. The Large Embden × Selected Chinese strain cross had a dressing percent of 63, significantly higher than 60–61% for the remaining strains or strain crosses. In general, the ranking of strains and strain crosses for liver weight was similar to rankings for body weights, except that the Small Embden-sired crosses were not significantly different from the Selected Chinese strain, and the Small and Large Embden-sired Selected Chinese crosses had similar liver weight. The Selected Synthetic strain had a significantly smaller neck than that of the other strains and strain crosses; Small Embden-sired crosses were not significantly different. Large Embden × Selected Chinese and Small Embden × Selected Synthetic strain crosses and the Selected Chinese strain had similar neck weight. When fat was expressed as a percentage of carcass weight, the strains and strain crosses had similar proportion of abdominal fat. On the other hand the Large Embden × Selected Chinese strain cross had significantly more intestinal fat (4.83%) than any of the strains and strain crosses (2.97 to 3.73%) and a similar proportion of total fat (10.87%) to the Small Embden × Selected Chinese strain cross (8.79%) but significantly more than the remaining strains and strain crosses (7.53 to 8.20%). The correlations of body weights at 9 and 16 wk of age with eviscerated carcass weight (0.65 and 0.90), abdominal fat weight (0.32 and 0.59), intestinal fat weight (0.27 and 0.55) and total fat weight (0.23 and 0.47) were deemed potentially useful. The correlations between percentage of fat parameters and body weights were low (0.20 a n d 0.37) or negligible. The inherent potential in the large-bodied Embden strain for growth can complement the small-bodied Selected Chinese strain that excels in egg production, fertility and hatchability to produce a strain cross with considerable promise for commercial production of goose meat. Key words: Chinese strain, Synthetic strain, Embden strain, body weights, abdominal and intestinal fat

Abstract Background: G-protein subunit beta 1 like ( GNB1L ) encodes a G-protein beta-subunit-like polypeptide. Chicken GNB1L is upregulated in the breast muscle of high feed efficiency chickens, and its expression is 1.52-fold that in low feed efficiency chickens. However, no report has described the effects of GNB1L indels on the chicken carcass and growth traits.Results: This study identified a 31-bp indel in the 5' untranslated region (UTR) of GNB1L and elucidated the effect of this gene mutation on the carcass and growth traits in chickens. The 31-bp indel showed a highly significant association with the body weight at 8 different stages and was significantly correlated with daily gains at 0 to 4 weeks and 4 to 8 weeks. Similarly, the mutation was significantly associated with small intestine length, breast width, breast depth and breast muscle weight. Moreover, DD and ID were superior genotypes for chicken growth and carcass traits.Conclusions: These results show that the 31-bp indel of GNB1L significantly affects chicken body weight and carcass traits and can serve as a candidate molecular marker for chicken genetics and breeding programs.

The purpose of this study was to examine the effect of short-term (7 days) undernutrition on Type I (soleus) and Type II (plantaris, gastrocnemius) muscles in rats. Male Sprague-Dawley rats ( N = 20) were randomly assigned to one of two groups: a control group ( n = 10) in which animals were allowed to have water and pellets ad libitum and an undernourished group ( n = 10) in which animals were allowed to have 37% of the total food intake of the control group and water ad libitum. Body weight and food intake were measured daily. After 7 days, rats were anesthetized and the soleus, plantaris, and gastrocnemius muscles and liver were dissected. Body weight, liver weight, muscle weight, Types I and II fiber cross-sectional area, and myofibrillar protein content were determined. After 7 days of undernutrition, the undernourished group showed significant decreases ( p < .05) compared to the control group in body weight, liver weight, muscle weight of soleus, plantaris, and gastrocnemius muscles, and cross-sectional areas of Types I and II fiber of the plantaris and gastrocnemius muscles.

Abstract. The objective of this study was to investigate the effect of sex of Japanese quails (Coturnix coturnix Japonica) on fattening performance and carcass characteristics. The quail chicks were divided into three groups, made up of 96 males or 92 females or 36 individuals of each sex, resulting in a total of 256 chicks. The chicks in the groups were raised using the same feeding regime (24% CP, 2900 kcal/kg ME) and housing conditions for 42 days. There were significant (P<0.01) differences between male and female groups in weekly live body weight (lbw) gain values on day 35, in average live body weight gain on days 35 and 42, and in lbw gain values between days 14 and 42. Slaughter weight and liver weight were significantly different between groups (P<0.01). The differences between the two sex in mixed group in average body weight gain, average lbw on days 35 and 42, average lbw gain, lbw gain between days 14 and 42, slaughter weight, hot carcass yield, and liver weight were found significant (P<0.01). Lbw, lbw gain, feed consumption, slaughter weight, hot carcass yield, weights of heart, liver and giblets were higher in female quails while feed conversion rate was lower. As a result, these data suggest that separate raising of male and female Japnese quails might be more advantageous.
