The aims of this study were to investigate whether the Sirtuin 1 (SIRT1) and Hear fatty acid binding protein (H-FABP) genes could be used as candidate genes in the breeding of yak. In 409 indigenous Chinese yaks, two single nucleotide polymorphisms (SNPs) were identified through DNA sequencing technology, including a SNP within the 5'UTR of SIRT1 (g.1906A>G), and a SNP in the exon 1 of H-FABP (g.6643C>T). The chi-square test suggested that all the variations were in Hardy-Weinberg equilibrium (P>0.05). An association analysis suggested that g.1906A>G of SIRT1 gene and g.6643C>T of H-FABP gene exhibited significant correlation with body weight and body length (P<0.01). These results indicated that these SNPs could be used as meritorious and available genetic markers in yak growth traits breeding. [ABSTRACT FROM AUTHOR] more...

Insulin-like growth factor I (IGF-1) influences gonadotrophin-releasing hormone (GnRH) neurons during puberty, and plays an important role in muscle growth in farm animals. The objective of this study was to estimate the genotype frequencies of the polymorphisms of IGF-1 and to determine associations between these polymorphisms and growth traits in Chinese Qinchuan cattle breeds. Five single nucleotide polymorphisms (SNPs), including one in intron 2 (g.5172T>G) and four in intron 3 (g.56495C>A, g.56501C>T, g.56801C>T and g.71090T>G) were identified according to the sequencing results of 487 individual of a Qinchuan cattle population. The chi-square test showed g.5172T>G, g.56495C>A and g.56801C>T were in Hardy-Weinberg equilibrium in all the samples. Six different haplotypes were identified, of which two major haplotypes had a frequency of 48.2% (-TCTTT-) and 16.3% (-TCCTT-). The single marker association analysis showed that the three polymorphisms (g.5172T>G, g.56501C>T and g.71090T>G) were significantly associated with growth traits (at P<0.01 or P<0.05). In conclusion, our results suggest that some polymorphisms in IGF-1 may play a role in determining one of the important genetic factors that influence growth traits in Chinese Qinchuan cattle.

- Abstract
In this study, aimed to determine some morphological traits of Honamlı Goat Breed which are widely reared in Turkey's Mediterranean Region, especially The Taurus Mountains. Data on live body weight, body length, height at withers, height at rump, heart girth, chest depth, tail length, head length, forehead width, the front and rear shank circumference were collected from goats (n=200) kept by traditional farmer. Regression analysis was carried out for live weight with all the linear body measurements. The data were classified on the basis of age and gender pattern. Age and sex significantly (P<0.01) influenced all the body measurements. Live body weight and some linear body measurements were highly (P<0.01) and positively correlated for all ages. Regression analysis show thatlive weight can be estimated using measurements of chest depth, body length, chest circumference, forehead width, and front shank circumference. As regards reproductive traits birth rate, infertility, single and twin births rates were calculated, 87%, 13%, 71% and 28% respectively. The litter size and kid rate values were calculated 1.28 and 1.11 respectively. In this study, a total of 190 heads kids were used, twin and single kids birth weight 3.58 kg and 3.95 kg, weaning weight 24.94 kg and 28.69 kg, suckling period daily weight gain, 0.180 kg and 0.205 kg respectively. The average survival rate at weaning (120 days) was found 80 %. [ABSTRACT FROM AUTHOR] more...

Myogenin gene encodes for skeletal muscle-specific transcription factors with highly conserved basic helix-loop-helix domain and play key role in growth and muscle development. In this study, the polymorphisms of myogenin gene were investigated to check whether they are associated with growth traits in Chinese-Tibetan sheep. In three sheep breeds with a total number of 632 individuals, three SNPs, including two in exon 1 (C109A and C183T) and one in intron 2 (A1403C) were found by DNA sequencing. Among those, C109A is a missense mutation (Gly37Arg). The single marker association analysis showed that the three mutations were significantly associated with growth traits (at P<0.01 or P<0.05). In conclusion, our results suggest that myogenin gene variation may be considered molecular markers for growth traits in Chinese-Tibetansheep. [ABSTRACT FROM AUTHOR] more...

Growth traits are under the control of multiple genes. Understanding the genetic information of related genes is helpful for the selection and breeding course through marker assisted selection. The aim of the current study was to investigate the association of A287G SNP in BMPR-1 B gene with growth traits in chicken. A single nucleotide polymorphism was identified in 240 individuals using the PCR-RFLP technique and confirmed by sequencing. The allelic and genotypic frequencies were compared, using the Chisquared test. Associations between the genotype of each polymorphism and the traits were analyzed using the General Linear Model of statistical software SAS. Three genotypes (AA, AG and GG) were detected in Fayoumi and Rhold Island Red chicken. Sequencing revealed one mutation (287→AG) in the genotype AA in comparison to the genotype GG. The A287G SNP of BMPR-1 B gene was associated significantly with body weight at 2nd (P=0.022), 3rd (P=0.034), 4th (P=0.011), 5th (P=0.035), 6th (P=0.001), 7th (P=0.008) and 8th (P=0.016) week of age. In conclusion, BMPR-1 B gene may be associated with body weight in chicken and may be considered in Marker Assisted Selection program to improve chicken growth performance.

The present study was conducted to compare the fertility of ewes, the survival rates, and the growth performance of lambs that were crossbred by mating German Black-Headed Mutton (GBM) rams with Kıvırcık ewes. The average lambing rates of the GBM x K(F1), Bandırma-ı and Bandırma-ıı genotype, and Kıvırcık ewes were 80.00%, 75.73%, 76.78%, and 83.72%, respectively. The differences in lambing rates between the genotypes were significant (P < 0.01). The genotypes had a significant effect on litter size at birth, but not on fecundity. The differences in lambs' survival rates between the genotypes were significant (P < 0.05). The birth weight (BW), weaning weight (WW), and yearling live weight (YLW) of the lambs were 3.77 kg, 34.11 kg, and 43.71 kg for the GBM x K (F1); 3.74 kg, 32.98 kg, and 44.91 kg for the Bandırma-ı; 3.73 kg, 33.18 kg, and 45.71 kg for the Bandırma-ıı; and 3.45 kg, 30.92 kg, and 42.22 kg for the Kıvırcık lambs. The results of this study showed that crossbreeding between the GBM and Kıvırcık breed did not significantly increase lamb production. However, crossbred lambs did not have significant survival problems when compared to native Kıvırcık lambs and had higher growth performance than purebred Kıvırcık lambs.

BULLS , *WEIGHT gain , *BODY weight , *CATTLE , *MALE livestock - Abstract
Charolais (C)-, Simmental (S)-, and Eastern Anatolian Red (EAR)-sired calves born in 2 locations in Eastern Anatolia were compared in terms of calving traits and preweaning growth characteristics. Breed of sire effects were significant (P < 0.01) for birth weight, 205-day weaning weight, average daily weight gain from birth to weaning, and some body measurements at birth. S- and C-sired calves were heavier at birth and larger for most body measurements at birth than EAR-sired calves. The C- and S-sired calves also had higher 205-day weight than the EAR-sired calves. Although the level of calving difficulty was higher in the S and C crosses, the differences were not statistically significant. Male calves had significantly (P < 0.01) heavier birth and 205-day weights, higher preweaning average daily gain and greater body measurements (e.g., height at withers, heart girth and cannon bone girth) than females. Location differences were also significant (P < 0.01) for survival rate from birth to weaning, preweaning growth rate and 205-day weight. In conclusion, although C- and S- sired calves performed similarly for most traits, all parameters of the preweaning growth were higher in calves sired by S and C bulls than in calves sired by EAR bulls. Therefore, both C and S could be considered as sire breeds for crossbreeding programs to be implemented in Eastern Anatolia, since these breeds did not cause an adverse influence on the calving and growth traits of the crossbred calves.

The possibilities of synchronizing lambing and increasing reproduction by using exogenous hormones in KarakaS ewes raised under rural farm conditions and growth characteristics of their lambs were investigated. 112 KarakaS ewes at 2-5 ages were randomly assigned into treatment (n = 45) and control (n = 67) groups during breeding season. The ewes in treatment group were placed with 60 mg Medroxyprogesterone acetate (MPA) containing intravaginal passaries for 14 days and received 600 IU PMSG injections at passary withdrawal. Ewes in the control group were not treated and allowed to mate at their natural estrus. Ram introduction for both groups was performed in pasture in village common flock in free mating system. Litter size and twinning rates for treatment and control groups were 1.06 and 1.04; and 6.45 and 4.08 %, respectively, for the first two cycles related to passary withdrawal (P > 0.05). When the expected lambing time was considered, the proportions of the lambed ewes in the first 7 and 10 days were 70.97% and 70.97% for treatment, and 20.41% and 26.53% for control group. The differences in lambing rates in both periods between groups were significant (P < 0.05). Birth weight, 1st, 2nd, 3rd and 4th month live weights, weaning weight and daily live weight gain in treatment group lambs were 3.63 ± 0.13, 9.30 ± 0.41, 16.54 ± 0.50, 23.62 ± 0.77, 31.97 ± 0.66, 31.57 ± 0.92 and 0.221 ± 0.008 kg; and, in control group lambs were 3.26 ± 0.12, 10.11 ± 0.44, 17.80 ± 0.53, 26.30 ± 0.82, 34.59 ± 0.75, 34.42 ± 0.96 and 0.244 ± 0.008 kg, respectively. Except birth weight, treatment group lambs' live weights in all periods were lower than control ones (P < 0.05 and P < 0.01). The results of this study indicate that in order to run studies to control reproduction by using exogenous hormones in rural conditions successfully some precautions and technical support are required.

BROWN trout , *TROUT , *FISH populations , *ANIMAL populations - Abstract
Some growth properties of the brown trout Salmo trutta macrostigma (Dumeril, 1858) in Tekederesi, which is a branch feeding the Karasu River, were investigated. The age composition of the population varied between I and V. The population was 64.81% female and 35.19% male and the differences between the sexes were statistcally significant (P < 0.05). The mean fork length and mean body weight of the 54 individuals examined were 16.58 cm and 53.15 g, respectively. The differences between the sexes according to age groups for fork length and total weight were not statistically significant (P > 0.05). The specific and relative growth for length and weight were maximum at the second age. The length-weight relationship of the population was calculated by the least squares method and the logarithmic equation was found to be Log W = -1.4684 + 2.590 Log FL (fork length). The mean condition factor of the population was 1.052, and the differences between the sexes were not statistcally significant (P > 0.05). [ABSTRACT FROM AUTHOR] more...

This study was conducted between March 2001 and February 2002 to investigate the size composition, growth characteristics and stock size of the pikeperch, Sander lucioperca (L. 1758), population of Lake Eğirdir. In the population, the rate of individuals more than 2 years of age and 20 cm was very low. The average length and weight of the commercial catch were also low. The length-weight relationship and von Bertalanffy growth equation were W = 0.006 L3.148 and Lt = 95.4*(1-e -0.0841(t+1.5638) ), respectively, and the average condition factor was 0.992. This last value is higher than those reported in other studies on the pikeperch population of this lake in the last 30 years. The total mortality and exploitation rates were 71.9% and 0.85, respectively. During the study, the annual catch of pikeperch was 50.2 t. In the lake, the stock of pikeperch over 14 cm in length was estimated as 601,299 individuals and 53.4 t in biomass. The present fishing effort should be decreased by 60% for maximum sustainable yield (MSY). In this way, 82.8 t of pikeperch could be obtained from the lake and the biomass of this species in the lake would be increased up to 350 t. [ABSTRACT FROM AUTHOR] more...

Growth and development traits of female Brown Swiss and Holstein Friesian cattle born in the Research Farm of the Agricultural College at Atatürk University were estimated by the Richards growth model by using weight-age data obtained between 1987 and 1998. A, B, k and m parameters of the Richards model were 501 ± 6.88 kg, 0.6666 ± 0.0262, 0.0581 ± 0.0019/month and 4.07 ± 0.44 for Brown Swiss, and 496 ± 7.40, 0.8041 ± 0.032, 0.0515 ± 0.0028/month and 2.64 ± 0.67 for Holstein Friesian cattle. Estimated birth weight and periodic weights taken between birth and 3 years of age for both breeds were close to each other. The highest daily weight gains of both breeds were obtained between birth and 6 months of age. Brown Swiss and Holstein Friesian cattle attained 65% and 95% of their mature live weights at 22.9 and 67.8 months, and 22.5 and 64.7 months, respectively. First calving age and live weight at first calving were 34.4 ± 0.4-months and 392 ± 3.2 kg for Brown Swiss, and 31.6 ± 0.5 months and 377 ± 5.2 kg for Holstein Friesian cattle. While the effects of the first calving age on B, m (P < 0.01) and A (P < 0.05) were statistically significant, its effect on the k parameter was not significant. Effects of calving at intermittent and consecutive years on the growth parameters were not significant. [ABSTRACT FROM AUTHOR] more...

Population structure studies of Aspius vorax (Heckel, 1843) are insufficient despite the species’ commercial importance in Karakaya Reservoir. Thus, the main purpose of this study was to acquire data on some population parameters (age, length- weight relationship, growth, fecundity and mortality) to evaluate the current status of A. vorax for a successful management plan. A total of 249 specimens (102 female and 147 male) were caught and the sex ratio was 1:1.44 (female to male). The age data was estimated from vertebra and ranged between ΙΙ and VΙΙ. Weight increase was allometrical for both sexes. Mean condition factor was CF = 0.839 ± 0.005. The von Bertalanffy growth parameter estimates were L∞ = 93.114 cm, K = 0.153 yrs-1 and to = -1.132 yrs for females, L∞ = 86.494 cm, K = 0.173 yrs-1 and to = -1.078 yrs for males and L∞ = 92.675 cm, K = 0.151 yrs-1 and to = -1. 151 yrs for all individuals. The mean fecundity was 102873. It was found that the stock of A. vorax had been overexploited (E =0.56) in Karakaya Reservoir and the fishing pressure should be reduced to achieve a sustainable fishery., Bu çalışmada, yüksek ekonomik önemine rağmen, Karakaya Baraj Gölü’nde yeterli düzeyde araştırılmamış olan Aspius vorax türünün bu ortamdaki mevcut durumunun belirlenebilmesi için bazı popülasyon parametreleri elde edilmiştir. Toplam olarak 249 birey (102 dişi, 147 erkek) incelenmiş ve eşey oranı erkekler yönüne 1:1,44 olarak tespit edilmiştir. Örnekler ΙΙ- VΙΙ yaş grupları arasında dağılım göstermiştir. Her iki eşey için de büyümenin allometric olduğu anlaşılmıştır. Ortalama kondisyon faktörü tüm bireyler için KF=0,839 ± 0,005 olarak elde edilmiştir. von Bertalanffy büyüme parametreleri dişiler için L∞ = 93,114 cm, K = 0,153 yıl-1 and to = -1,132 yıl, erkekler için L∞ = 86,494 cm, K = 0,173 yıl-1 and to = -1,078 yıl ve tüm bireyler için L∞ = 92,675 cm, K = 0,151 yıl-1 and to = 1,151 yıl olarak hesaplanmıştır. Ortalama yumurta veriminin 102873 olduğu görülmüştür. Yapılan hesaplamalar sonucu Karakaya Baraj Gölü’nde A. vorax stokunun aşırı şekilde sömürüldüğü (E=0,76) ve bu türün bahsedilen ortamda sürdürülebilir avcılığı için üzerindeki av baskısının azaltılması gerektiği anlaşılmıştır more...

Bu çalışmada, Karasu Irmağı'nın Aşkale Mevkiinden Şubat 1996 ve Ocak 1997 tarihleri arasında yakalanan 375 adet Gümüş Balığı (Chalcalburnus mosullensis, Heckel 1843)'nın populasyon yapısı ve büyüme özellikleri incelenmiştir. Populasyonda yaş kompozisyonu I-VI yaşlar arasında dağılım göstermiş olup, %42.13'lük oranla II. yaş grubunun dominant olduğu gözlenmiştir. Populasyonun %51.74'ünü dişiler, %48.26'sını ise erkekler oluşturmuştur. Çatal boy erkeklerde 8.9-18.1 cm, canlı ağırlık 3.6-67.9 g, dişilerde 8.5-18.5 cm, 5.1-79.5 g arasında değişmiştir. Boyca ve ağırlıkça oransal ve spesifik büyüme en yüksek II. yaşta gerçekleşmiştir. Yaş-boy, yaş-ağırlık (Von Bertalanffy eşitlikleri) ve logaritmik boy-ağırlık ilişkileri erkek ve dişiler için sırasıyla; Lt= 20.41 (1-e-°.2485(t+1.47)), L = 21.59 (1-e-0.1978(t+2.13)), W = 80.77 (1-e-0.2485^1.47))2.828, Wt= 103.63 (1-e-0.978(t+2.13))3.082 ve LogW= -1.796+2.828LogFL (r=0.943), LogW= - 2.097+3.082LogFL (r=0.946) olarak hesaplanmıştır. Ortalama kondisyon faktörü erkeklerde 1.023 dişilerde ise 1.047 olarak hesaplanmıştır. In this study, the population structure and growth properties of Chalcalburnus mossulensis (Heckel, 1843) caught from Aşkale Region of River Karasu betwen February 1996 and January 1997 were examined. The age composition of population varied between I and VI ages, and the most abundant age group was the third age group (42.13%). The population was composed of 51.74% females and 48.26% males. The fork length and the body weights of males and females varied between 8.9-18.1 cm, 3.6-67.9 g and 8.5-18.5 cm, 5.1-79.5 g respectively. The specific and relative growth for length and weight were maximum in the second age. The age-length, age-weight (Von Bertalanffy equations) and length- weight relationships of males and females were calculated as Lt= 20.41 (1-e-0.2485(t+1.47)), Lt= 21.59 (1-e-°-1978(t+2-13)), W = 80.77 (i-e-0-2485^-47))2-828, W = 103.63 (1_e-°-1978(t+2.i3))3.082 and LogW= -1.796+2.828LogFL (r=0.943), LogW= -2.097+3.082LogFL (r= 0.946) respectively. The mean condition factor of males and females were found as 1.023 and 1.047 respectively. more...
