Abstract. There are two types of Japanese quails, reared in Europe – dual-purpose and meat. The aim of the present study was to made an economic analysis of fattening quails from the dual-purpose and heavy production types. Three groups were formed – group 1 (dual-purpose), groups 2 and 3 (heavy type), reared in cages. After quails sexing on the 16th day of age, there were formed six subgroups: 1m, 1f, 2m, 2f, 3m and 3f. Fattening period lasted until 35 days of age. For revenues calculation produced meat and edible offal data per m2, were used. Costs calculation include consumed feed for the period, day-old quail, and other costs. The main production costs were associated with feed and day-old quails: from 80.3 and 82.6% of all costs in the studied groups. The anticipated revenues from produce in group 2 were 10 EUR/m2 higher than those in group 1, and for group 3 – 10.21 EUR/m2 higher than group А. The results indicate that meat type quails fattening is the most economically efficient in quail meat production. Producing quail edible offal is still not developed but could be beneficial for efficiency of quail fattening small farms.

Analyzing marker-assisted breeding is an important method utilized in modern molecular breeding. Recent studies have determined that a large number of molecular markers appear to explain the impact of “lost heritability” on human height. Therefore, it is necessary to locate molecular marker sites in poultry and investigate the possible molecular mechanisms governing their effects. In this study, we found a 104-bp insertion/deletion polymorphism in the 5′UTR of the ADPRHL1 gene through resequencing. In cross-designed F2 resource groups, the indel was significantly associated with weight at 0, 2, 4, 6, and 10 weeks and a number of other traits [carcass weight (CW), semi-evisceration weight (SEW), evisceration weight (EW), claw weight (CLW), wings weight (DWW), gizzard weight (GW), pancreas weight (PW), chest muscle weight (CMW), leg weight (LW), leg muscle weight (LMW), shedding Weight (SW), liver rate (LR), and leg muscle rate (LMR)] (P < 0.05). In brief, the insertion-insertion (II) genotype was significantly associated with the greatest growth traits and meat quality traits, whereas the values associated with the insertion-deletion (ID) genotype were the lowest in the F2 reciprocal cross chickens. The mutation sites were genotyped in 4,526 individuals from 12 different chicken breeds and cross-designed F2 resource groups. The II genotype is the most important genotype in commercial broilers, and the I allele frequency observed in these breeds is relatively high. Deletion mutations tend to be fixed in commercial broilers. However, there is still considerable great potential for breeding in dual-purpose chickens and commercial laying hens. A luciferase reporter assay showed that the II genotype of the ADPRHL1 gene possessed 2.49-fold higher promoter activity than the DD genotype (P < 0.05). We hypothesized that this indel might affect the transcriptional activity of ADPRHL1, thereby affecting the growth traits of chickens. These findings may help to elucidate the function of the ADPRHL1 gene and facilitate enhanced reproduction in the chicken industry.

Genetic variation from a combination of four breeds of chickens (Anak Titan, Alpha, Giriraja and Normal indigenous chickens) were examined for importance of sire, dam, season and sex on growth traits using a Mixed-model Least-Squares and Maximum LIkelihood computer program. The results show that sire and dam genotypes significantly (P<0.05) affected growth. Anak Titan cocks and hens performed best in body weight (BW) with values ranging from 38.45±0.74g and 40.21±0.66g at day old to 1135.93  35.67g and 953.38  35.38g at week 12 respectively. Normal indigenous and Alpha improved indigenous performed better in linear body parameters. Genetic correlation coefficients among parameters for all the breeds were generally high. Positive estimates ranged from 0.15 for breast girth (BG) and keel length (KL) at week four to 0.99 for BG-KL at week tweve while negative values ranged from -0.783 for body weight (BW) and wing length (WL) at week four to -0.99 for BW-BG at week twelve. Heritability estimates for body weight ranged from 0.14 at week one to 0.63 at week four. It can be concluded that appreciable variation exists for growth traits among the strains of chickens. Such variations can be utilized for improvement in the present emvironment.

The aim of the present study was to investigate the meat colour characteristics, using CIE L*a*b* colour description system, of quails from the two main production types reared in Europe: the intermediate heavy (dual-purpose) and heavy (meat-type). Quails were separated by gender in male and female subgroups, as follows: Am, Af, Dm, Df, Mm and Mf, where A group was dual-purpose and D and M groups were from heavy type. Meat colour characteristics of the breast (M. pectoralis superficialis), tenders (M. pectoralis profundus) and leg muscles (M. Iliotibialis lateralis pars postacetabularis) were evaluated on post mortem hour 24 in CIE L*a*b* colour description system. On the basis of L*, a* and b* values, the chroma (С*), colour index (CI) and meat colour index (MCI) were calculated. The lateral surface of M. p. superficialis was substantially darker in the light all-purpose type than in the heavy group М (р<0.001). The lowest lightness values (L*) were detected on M. p. superficialis facies medialis and the outer surface of M. p. profundus. The highest average meat redness was detected on M. p. superficialis facies medialis and the lowest - in thigh muscles (M. iliotibialis). Average yellowness (b*) of all studied muscles were positive in all groups of quails, with statistically significantly lower values in females vs males. The sex-related analysis showed that indices CI and MCI were considerably lower for both surfaces of M. p. superficialis in subgroup Am than in subgroups Dm and Mm (р<0.001). Similar differences were found out for the thigh muscle (р<0.05).

Abstract. Knowledge of genetic parameters is essential for improved reproductive management and increased yield. Quantitative analysis of genetic parameters is lacking for many breeds of buffaloes. This article provides the first estimate of genetic parameters for dual purpose (meat and milk) Brazilian Jaffarabadi buffaloes, using Bayesian inference. Data on milk yield (MY), lactation length (LL), weight at 205 days (W205) and 365 (W365) days of age, and average daily gain (ADG) from 205 to 365 days of age were collected in two herds. Bivariate analyses (using the program MTGSAM) were performed with the Gibbs sampler to obtain estimates of variance and covariance. Average lactation milk yield and lactation length were 1620.2±450.9 kg and 257.6±46.8 days, respectively, and the mean values for weight traits (kg) were 181.6±63.3 (W205), 298.04±116.1 (W365), and 0.73±0.35 (ADG). Heritability estimates (modes) were 0.16 for MY, 0.10 for LL, 0.43 for W205, 0.48 for W365 and 0.32 for ADG. There was a high genetic correlation (0.96) between milk yield and lactation length and very high genetic correlations (0.99) between the three growth traits. Our data suggest that both milk production and growth traits have clear potential for yield improvement through direct selection in this dual purpose breed. The selection for weight at an early age would be successful and selection for MY can be performed in the first lactation.
