Some Reproductive Characteristics of Honamlı Goats
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.
TURKISH JOURNAL OF VETERINARY AND ANIMAL SCIENCES
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
Morphometric Dimentions of the Genitalia of Savanna Brown Goats between Day 24 and 30 Postpartum
This study was carried out to determine changes in ovarian and uterine dimensions in Savanna Brown (SB) goats between days 24 and 30 postpartum (pp). The mean (± sem) weight of the right ovary (ROV) was significantly higher (P < 0.05) at day 28 pp. The diameter of the largest follicle in the ROV was greater (P < 0.05) at day 28 pp. The weight of follicular fluid (FF) from all follicles in both ovaries was heavier (P< 0.05) at day 28 pp. The number of follicles > 0.3 cm in diameter in the ROV was higher (P< 0.05) at day 30 pp than day 26 pp. Mean weight of FF from the left ovary (LOV) was heavier (P< 0.05) than from the ROV during the period of study. The inter-caruncular distance in both the right (Rh) and left (Lh) uterine horns was longer (P< 0.05) at day 30 pp. The left oviduct was longer (P <0.05) than the right oviduct at day 30 pp. It is concluded that pp ovarian follicle activity was higher in the ROV than LOV and inter-carunucular distance and left oviductal length were significantly longer between days 28 and 30 pp.

Background: Improved reproduction requires understanding the biometry of goats' female reproductive system. Objectives: The present study was conducted to record the biometry of the female genital organs of the Arabia (Arbia) goats in Algeria according to age, body condition score, and pregnancy. Methods: A total of 149 reproductive tracts (from 80.54% non-pregnant and 19.46% pregnant goats) from three slaughterhouses were collected and measured. Each organ's length, width, thickness, and weight were measured using slide calipers and an electric weighing balance. The ages of the fetuses in pregnant goats were determined by measuring their crown-rump length. Analysis was carried out using SPSS software, version 21. Results: The reproductive tract dimensions increase with age, body condition score, and stages of pregnancy. The left ovary's weight, length, and width showed very significant (P<0.001) increases across age. The measurements of the uterine horn (except thickness) increased significantly (P<0.001) with age. The fallopian tube, the uterine body, and the cervix measures showed significant increases (P<0.001) between the first and third age groups. The ovary and the uterine body dimensions showed highly significant (P<0.001) increases across body condition scores. Pregnancy had no significant effect on the ovary and cervix dimensions. The uterine horn measurements showed significant increases (P<0.05) throughout gestation, and those of the uterine body showed highly significant increases (P<0.001) along the pregnancy stages. Conclusion: This study will provide baseline information on the morphology of the female Arbia breed reproductive system.

Mellado, M., Mellado, J., García, J.E. and López, R. 2005. Lifetime reproductive performance of goats as a function of growth traits and reproductive performance early in life. J. Appl. Anim. Res., 27: 113–116.The primary aim of this study was to evaluate the association between reproductive performance of 476 dairy goats in their first reproductive cycle with reproductive efficiency late in their life. Does with an initially high body weight at birth (>3.2 kg) subsequently produced litters that were 6% larger than does with <2.7 kg at birth. Does with the higher weight gains as kids, had litters that were 8 and 15% heavier at birth and at 25 d of age throughout adult life than goats with the lowest gains during the first month of life. Does that gave birth to multiples in their first reproductive cycle subsequently had 10% more (P<0.01) average kids per doe joined, and 8% more (P<0.01) litter weight at birth I doe joined than does that had single kids at their first reproductive opportunity. It was concluded that managing for optimum doe weight as kids and strict culling of does with lighter litters at birth or at 25 d of age during their first kidding seems to be a practical option to improve lifetime reproductive performance in dairy goats without nutritional restrictions.
Size of genitalia of Iranian goats in pregnancy
Bangladesh Veterinarian, 2012
Reproductive organs with no apparent abnormalities were collected from seventy pregnant goats slaughtered at Ahvaz abattoir of southern Iran. The weight of uteri and ovaries, diameter and length of gravid and non-gravid uterine horns, and diameter and length and thickness of ovaries were measured. Gravid uterine weight increased (4205.0 ± 962.7g in last month) with the advancement of pregnancy. The dimensions of ovaries in different months of pregnancy were not significantly different.

This study was carried out to determine the effect of non-genetic factors on growth and reproductive traits in Saanen goats. For this aim, total of 274 Saanen goats and kids were investigated for growth and reproductive traits in South Marmara Region of Turkey. Fertility parameters were evaluated during two reproductive years. Saanen kids were measured from birth to 6 months of life. The average live weights at birth, weaning, 60 th , 90 th , 120 th and 180 th days of age were calculated and determined as 3.05±0.04kg, 11.80±0.27kg, 12.26±0.08kg, 14.20±0.32kg, 17.41±0.45kg, 25.01±0.65kg, respectively. The effects of sex and birth type on live weights until 90 th days of age; maternal age only on birth weight; month at birth on all of investigated days were found significant statistically. The pregnancy, birth rate per pregnancy (BR P), birth rate per mating (BR M), infertility, abortion, kidding rate (single, twin or triplet), survival rate (until weaning), number of kids per parturition (NKP), number of kids per mating (NKM) were found; 92.98%,
