Selcuk Journal of Agricultural and Food Sciences
This study was carried out to investigate the some reproduction characteristics of Honamlı goat breed that are rearing commonly in Taurus Mountains in the Mediterranean region of Turkey. The materials of the study was formed with the five years records from 2011 to 2016 of 27 flocks (average 220 bucks and 4400 does) chosen from 36 flocks within the scope of National Public Small Ruminant Improvement Project, which was raised under extensive conditions in Beyşehir and Derebucak districts of Konya. At the end of the research; kidding rate, survival rate, twin birth rate, fecundity, litter size and the averages for birth weight, weaning weight and daily weight gains for the five consecutive years were found as 85%,87%,15%,0.94,1.10,3.64 kg,19.14 kg,0.180 kg, respectively. Effects of farm, birth type and gender on live weights and daily weight gains were found to be statistically significant (P<0.01).
Prenatal development of Iranian goat fetuses
The goal of the present study was to establish the basic information about the prenatal development of Iranian goats. Pregnant goat reproductive organs which had no apparent abnormalities were collected from Ahvaz city abattoir (southern Iran) for study of prenatal development of fetuses. After splitting of uteri and separating of fetal membranes fetuses were expelled. Then the weights of fetuses and fetal membranes, lengths of tibia, radius, crown-rump lengths (CRL) and, chest circumference were measured. Analyses of data were done by SPSS.16 software and comparisons of mean values were performed by Duncan's method. The results showed that the lengths of tibia, radius, CRL and chest circumferences were increased by approaching the final months of pregnancy. Also the weights of fetuses and fetal membranes were increased from early to late stages of fetal ages. It is concluded that various parameters of fetal intra uterine growth could be attributed to the breed, nutritional status, age and genetic factors
Determination of factors affecting pregnancy rate in Turkish Saanen goats
Ankara Üniversitesi Veteriner Fakültesi Dergisi, 2014
Reproductive performance in goats is one of the important trait which has a major effect on commercial farm income. The objective of this study was to evaluate the factors effecting reproductive performance of Turkish Saanen goats with using Logistic Regression. The records of Turkish Saanen goats, aged 2-4 (2.05 ± 1.19), were used in this study. Data were analyzed with using stepwise multivariate logistic regression analyses. The response variable was pregnancy and the model included milk yield, insemination type and insemination day. As a result, milk yield at the insemination day (P<0.001) was one of the major factor with insemination type (P<0.05) and the increase in insemination day (P<0.05) was tend to be significant factor for the likelihood of pregnancy and were determined as the main factors. Milk yield at the insemination day 99.9% effects pregnancy and artificially inseminated goats were 2.4 times less likely to become pregnant than the naturally inseminated goats. The increase of insemination day also caused 30.0% increase in likelihood of pregnancy. As a conclusion, milk yield on the insemination day is the most significant factor affecting the pregnancy likelihood in Saanen goats. On the other hand, artificial insemination is not very effective to get higher pregnancy rates in Saanen goats.

This study was carried out to determine some reproductive and kid growth characteristics as well as some lactation traits of Kilis goats raised under semiintensive conditions in Kilis Province in Turkey. The animal material of the study comprised 502, 698, and 753 heads of Kilis goats in 2013, 2014, and 2015, respectively. At the end of study, multiple birth rates were calculated between 31.5% and 35.7% during the years. Lactation length and lactation milk yield were determined to be between 207.1 ± 0.81 and 232.4 ± 0.65 days and between 315.7 ± 4.16 l and 375.6 ± 3.4 L, respectively during the years. Lactation characteristics of the goats changed due to lactation number. Birth and weaning weights were found as 3.6 ± 0.02 kg and 12.3 ± 0.04 kg, respectively. It was also detected that birth weight was affected by year, sex, birth type, and farm diversity while weaning weight was not affected by birth type. It was concluded that the Kilis goat has satisfactory milk yield and multiple kidding rates in semiintensive conditions in Kilis Province.
Determination of Pre-parturition and Post-parturition Behaviors of Norduz Goats
Kafkas Universitesi Veteriner Fakultesi Dergisi, 2009
The objective of this study was to determine of pre-parturition and post-parturition behaviors of Norduz Goats. Animal subjects consisted of 18 primiparous single-birth does aged 2-3 years. During the kidding time, the goats were recorded with digital video cameras for one hour pre parturition and 24 h post-parturition in order to register parturition traits. Twelve does (67%) gave birth while being recumbent and six (33%) while standing (P<0.01). The majority of kidding (n=12, 67 %) occurred between 12.00-18.00 h, followed by 18.00-24.00 h (n=4, 22%) and 00.00-06.00 h (n=2, 11%). The majority of does (n= 83 %) accepted and nursed their kids after parturition; however, 3 does (17%) rejected their kids after parturition. Of those does who accepted their kids, 14 (93%) refrained from feeding throughout the observation period, whereas only 1 (7%) left her kid to feed during this period (1/15). The duration of parturition, the duration of placenta expulsion, the latency to first sniffing, the latency to first licking, the latency to first suckling, the duration of first suckling, the latency to first standing, and the duration of standing at the birth site were 21.99±2.49 min., 120.74±6.98 min., 0.64±0.39 min., 0.82±0.22 min., 22.65±2.37 min., 0.62±0.13 min., 17.50±2.42 min. and 4> hrs., respectively. These results clearly suggest that in Norduz goats the parturition behavior occurs within four hours after the parturition, and also Norduz goats are observed to be having a normal maternal behavior regarding with investigated behavioral characteristics
Obstetrical problems and their management in Iraqi goats
Small Ruminant Research, 1994
The study was conducted on 576 Iraqi goats suffering from dystocia (n = 308), uterine prolapse (n = 115), retained placenta (n = 95) and postpartum metritis (n = 58). Treatment of different types of dystocia in goats included medical (hormonal; n = 36), manual (correction and traction; n = 148) and surgical (Caesarean section; n = 124). Efficiency of each treatment was: 66.6%, 82.4% and 93.5%, respectively, with a significant difference (P < 0.01 ) between methods. Does with uterine prolapse were treated by repositioning and suturing the vulva. Good prognoses were obtained in 80% (92/115 ) of cases. Animals affected with retained placenta were treated by manual removal of placenta plus L.A. tetracycline injection (n = 33) or 2 mg oestradiol benzoate plus 20 i.u. oxytocin i.m. (n = 32), or 7.5 mg prostaglandin (PGF2,, i.m. (n = 30). High success rate was obtained (86.6%) with the PGF2,-treated group. Manual treatment with antibiotics and treatment with oestradiol benzoate plus oxytocin had 60.6% and 62.5% response, respectively, with a significant difference between prostaglandin-treated group and others (P < 0.01 ). Goats with postpartum metritis were subjected to 20 mg/kg BW L.A. tetracycline i.m. (group 1 ; n = 20); 20 mg/ kg BW LA tetracycline i.m. plus oestradiol benzoate ( 2 mg i.m. ) followed by 20 i.u. of oxytocin i.m. (group 2; n = 20); received 20 mg/kg BW LA tetracycline i.m. plus 7.5 mg prostaglandin F2~ i.m. (group 3; n=20). A high success rate (88.8%) was obtained in the third group, while the other treatments had 55% and 75% responses in groups 1 and 2, respectively (P < 0.01 ). Caesarean section was the safest method for treatment of caprine dystocia. Injection of PGF2,, or oxytocin plus oestradiol alone or in combination with antibiotic directly after parturition will reduce the incidence of retained placenta and postpartum metritis.

Relationship between placental traits and birth related factors in Damascus goats
Livestock Science, 2014
The relationship between placental traits and litter related factors of Damascus goats were investigated. In total, 39 Damascus goats of same age were used in the study. One-way ANOVA was used for statistical comparison and a Poisson regression analysis was used to determine the effect of litter size and sex on cotyledon number. Pearson correlation coefficient was used to determine the relationships between variables. Cotyledon efficiency (CE), cotyledon number (CN), number of small, medium and large cotyledons, cotyledon density (CD), individual cotyledon surface area and litter weight have been determined significant for litter size (p o0.05). A positive correlation was revealed between placental weight (PW) individual cotyledon weight (ICW) (r ¼ 0.88, P o0.05), cotyledon weight (CW) (r ¼ 0.64, P o0.05), large cotyledons number (LCN) (r ¼ 0.54, P o 0.05), also between birth weight (BW) and PW (r ¼0.47, P o 0.05) and litter weight (LW) (r¼ 0.38, P o 0.01). CW was negatively correlated with CD (r ¼ À0.55, P o 0.05) and placental efficiency (PE) (r ¼ À0.82, P o 0.05). PW and PE were found highest in twin births. Single kids at an average of 4704 7 147 g were born heavier than twin kids (4315 7 333 g). While CW did not differ between single and twin births ICW was much higher (double) for twins. Sex had no effect on CN (P4 0.05); however litter size was found significant according to Poisson regression results. The most important finding of this study was the significant variance in cotyledon numbers between single and twin births. There was a notable increase of small and medium cotyledon numbers and a significant decrease of large cotyledons for single births while the exact opposite occurred for twin births. This significant correlation initiated to a new parameter for measuring the efficiency of placental exchange.

This study aimed to determine the reproductive characteristics of Saanen goats of Australian origin using an estrus synchronization program with hormones (MPA and PMSG) in two different mating periods (Period I and Period II) and to investigate the survival rates and growth performances of kids. According to the results of the research, it was determined that pregnancy rate and litter size were higher in the mating period I (87% and 2.16) compared to mating period II (80.5% and 2.03), and it is hypothesized that this situation is related to the length of dry period of the goats. Although the mortality rate (P˂0.001), and body weight (P˂0.05) at birth were affected by kidding season, the survival rate and their body weights of the Saanen-kids at days 30, 60, 90, and 120 were not affected by the kidding season (P>0.05). These results indicate that the kidding season should be an environmental factor to be taken into account when planning the production. In addition to this, it is important to optimize the care and management conditions, especially during the kidding season, due to the high multiple birth types for the estrus synchronization program in Saanen goats.

The present study was carried out to determine the growth and survival rate, the environmental factors affecting these characteristics and the reproductive characteristics of Hair goats raised under farm conditions in the province of Adıyaman, Turkey, for the first time in the region, from birth to weaning (90 days). The birth weight data of 13,751 kids born to Hair goats raised in 48 different enterprises between 2016-2018 was acquired, and the weaning weight data of 12,855 kids were used in the study. As a general average over three years, the birth weight, 60-day live weight, weaning weight and daily live weight gain (DLWG) of the kids were 2.80±0.007, 11.34±0.041, 15.59±0.062 kg and 141.72±0.690 g, respectively. Among the environmental factors examined related to these characteristics, the effects of the dam's age, the enterprise, the year of birth, the gender and the birth type were found to be statistically significant (p<0.05, p<0.01, p<0.001). The average survival rate of kids in weaning was 93.48%. Aside from gender, the effect of the dam's age, year of birth and birth type on the survival rate was determined to be significant (p<0.001). In the study, litter size and twin birth rates were generally 1.10 and 8.71%, respectively. The results of this research, based on the above data, revealed Hair goat breeding to be sustainable and successful in the region.
