The inbreeding coefficient refers to the degree of advancing of any society. In 2006 an experiment was conducted to find the inbreeding coefficient in the middle Euphrates area of Iraq (Al-Qadisiyia and Babylon) and to study the relationship between the related and unrelated marriages as well as reproductive parameters. Results indicated that inbreeding coefficient was (F=0.0167). The percentage of unrelated marriage was higher in ( Al-Qadisiyia 44.9% compared to Babylon 36.5%) and the total was 55.3% Non–fertile families in middle Euphrates region was 2.5% No relationship was found between fertility outcome and consanguineous, non-consanguineous marriage.

Effective Service

Practical use is made of an increase in the ovulation rate of gilts over the first few oestrous cycles. In large herds it may well be easier to increase the interval between entry into the herd and first service in order to improve the size of the first litter. The present study considers existing herd records, taken from the Easicare management system, in which the relationship between age at first litter and reproductive parameters in the first parity are examined. A total of 3778 gilt litters were involved, mostly Large White or Landrace, from 14 nucleus or multiplication herds. Average age at first litter ranged from 342 to 376 days across herds and total numbers born per litter from 9.03 to 11.27. Within herd variation in age at first service ranged from a standard deviation of 19 days to 40 days, that of litter size being more consistent, ranging from 2.45 to 3.21. The within herd regressions between these traits were generally small, averaging 0.007 piglets per day, and insignificant (p>0.05).

ABSTRACT Background: Intellectual disability (ID) can be inherited in families through consanguineous marriage. The ID in an individual can be associated with the ID, epilepsy, and mental illness in their parents. Such connections can be seen more closely among consanguineous marriages in tribal and nontribal population in India. Objective: This study shows a few common patterns of the consanguineous relationship in the parents of children with ID in India. Materials and Methods: This is a case series research design. Extreme or deviant case sampling was applied. Data were collected in homes, camps, and clinical settings in the Barwani district of Madhya Pradesh, India. The patterns of consanguineous marriages and the relationship between children with ID and their relatives with ID, epilepsy, and mental illness were analyzed and reported with pedigree charts. Results: Multiple patterns of consanguineous marriages in tribal and nontribal populations were observed. ID was found to be associated in children with their relatives of the first, second, and third generations. Conclusion: ID may inherit in individuals from their relatives of the first, second, and third generations who have ID, epilepsy, or mental illness and married in the relationship. Appropriate knowledge, guidance, and counseling may be provided to potential couples before planning a consanguineous marriage.

Effect Of Age

Abstract The aim of the study was to determine the relationship between age and temperament as well as reproductive results in female raccoon dogs. The study was carried out at two raccoon dog breeding farms located in south-eastern Poland. A total of 189 foundation stock females were evaluated for temperament using a modified behavioural empathy test. Animals were classified into five temperament groups: very fearful (VF), fearful (F), confident (C), aggressive (A) and very aggressive (VA). The animals with calm temperament (C) formed the largest group (49.9%) whereas the smallest number of animals was classified as VA (5.6%). The influence of age on the temperament of raccoon dog females and the number of young born and weaned (P≤0.01) was revealed. At the same time, temperament did not affect reproductive parameters (P>0.05). Summing up, the results of this study indicate lack of correlation between temperament and reproductive parameters. It can be assumed that the elimination of aggressive animals from the foundation stock will not compromise production results and can help to facilitate handling and improve animal welfare.

Control Study

Introduction: Congenital Hypothyroidism (CHT) is a condition in which the thyroid stimulating hormone (TSH) is equal to or more than 10 MU/L and the thyroxine hormone (T4) is less than 6.5 M/L. CHT is one of the most important preventable causes of mental retardation in infants. The present study aimed to determine the incidence of CHT and the associated factors. Method: At first, a descriptive research was done to examine the incidence of CHT in the period of 2006-2014 in Shadegan city, Khuzestan province. Then, a case-reference and a case-control study was done to investigate the relationship between CHT and demographic characteristics, environmental factors and medical factors. The cases in this study were neonates with CHT (transient and permanent). The results showed that the venous TSH score for these neonates was equal to or higher than 10 MU/L and their T4 level was lower than 6.5 MU/L. The subjects in the control group were infants that did not suffer from CHT whose venous TSH and T4 scores were lower than 10 MU/L and higher than 6.5 MU/L, respectively. The relationship between the aforementioned factors with the illness was determined using multiple logistic regression statistical model. The SPSS 18 software was used to analyze the findings of this research. Findings: In this study, the incidences of neonatal CHT in Shadegan were 17, 21.5 and 12.59 per thousand newborn infants in 2012, 2013 and 2014, respectively. Conclusion: The parents' record of consanguineous marriage increases the likelihood of developing CHT; therefore, couples that wish to marry have to be educated and made aware in marriage counseling centers, both in the field of consanguineous marriage and CHT.

SummaryIn order to investigate the association between mean inbreeding coefficient (α) and healthy life expectancy at birth (HALE; years) the present ecological study on 63 countries was done. Statistical analysis showed that HALE negatively and positively correlated with log10α and log10GNI per capita, respectively (p<0.001). It should be noted that log10α and log10GNI per capita were significantly correlated with each other (p<0.001). After controlling for log10GNI per capita, significant negative correlations between log10α and HALE were observed. The countries were stratified according to their GNI per capita into low- and high-income countries. In countries with high income, after controlling for log10GNI per capita, the correlation between HALE at birth and log10α was significant (for males r=−0.399, df=32, p=0.001; for females r=−0.683, df=32, p<0.001). In high-income Asian and African countries, where consanguineous marriage is common, after controlling for log10GNI per capita, the correlation between HALE at birth and log10α was significant (for males r=−0.819, df=8, p=0.004; for females r=−0.936, df=8, p<0.001). It seems that consanguinity influences HALE independent of country income.

Cultivar Grillo vines are characterized by problems with flower biology (the fertility of basal buds) and fructification (millerandage). In this study, to manage the variability in bunch weight with winter pruning and to program others canopy management practices (i.e. early defoliation), three different treatments of bud load were set up by leaving the cane with 3, 6 or 10 buds. The effects of bud load and cane length were studies regarding bud fertility, shoot leaf area, and the number of flowers and berries, as well as the relationship between leaf area and percentage of fruit set, leaf area/flower and percentage of fruit set, and the number of hens and chicks berries. Shoots in the distal position had higher values of fertility and inflorescences with a greater number of flowers, while no ‘apical’ effect of the buds emerged. A good relationship was found between fruit set and the number of flowers, leaf area at flowering and yield, and square centimeters/flower and percentage of fruit set. Cane length was found to be a valid tool for managing bunch weight variability; the value of the leaf area/flower can be used to program early defoliation practice carried out to manage berry set.

Intramuscular Fat Content

The fatness and muscularity of Polish Landrace, Polish Large White gilts and sows and their hybrids were determined on the basis of ultrasound measurements in three consecutive parities, and then the relationship between these parameters and reproductive performance was established. Ultrasound measurements demonstrated the highest fat thickness in first parity and the highest fat area over LD muscle in hybrid gilts (PL × PLW). Pure-bred gilts were characterized by poorer muscularity. Fatness level affected the reproductive parameters of females in which the thickness of backfat in UP2 point was above 22.25 mm, the thickness of backfat in UP4 point was above 17.36 mm and the fat area over LD muscle was above 25.81 cm2. These females achieved better farrowing rates and higher numbers of born piglets. Decreased mortality, higher gains of piglets and higher body weight at weaning were observed, and the weaning to service interval was shortened in fatter females. Intramuscular fat content did not affect reproductive parameters. Muscularity negatively affected reproductive performance parameters, except gestation period. Too-high muscularity was related to the lowest levels of reproductive indices. The analysis of gilts and sows’ fatness and muscularity levels can help to predict their reproductive performance in the future and thus optimize production results.
