A selection experiment with Romney Marsh sheep was used to evaluate direct responses to selection. Two flocks were maintained; a) the selection line formed in 1979 by the Romney Group Breeders to select for high prolificacy, defined as the number of live lambs born per ewe joined per year and b) a control line, established in 1982, where flock replacements were chosen at random. Predicted responses per year of birth female group and per year respectively were 0.033 and 0.027 live lambs. The rate of predicted response per year was within the theoretical expected range from 0.01 to 0.03 of the mean. The rates of realized response in prolificacy per year of birth female group and per year respectively were 0.026 and 0.021. These estimates of realized responses represented between 0.01 and 0.02 of the control line mean per year.

Purpose: In this study effects of a paternal participation program during cesarean section on paternal infant attachment were investigate. The experimental treatment was an integrative nursing intervention to promote father to infant attachment. Methods: Study design was a non-equivalent control group posttest design. The program consisted of emotional support to spouse and father towards infant attachment immediately following cesarean birth. Participants were 66 men, partners of women with normal full term pregnancy having a cesarean section with spinal or epidural anesthesia, (experimental group, 34; control group, 32). The experiment was carried out from August 1 to October 30, 2010. Control group data were obtained from May 1 to June 30, 2012. Posttest was performed 72 hours after cesarean birth. A self-report questionnaire including a paternal attachment instrument was used. Data were analyzed using t-test, propensity score matching, and analysis of covariance with the SPSS/WIN 18.0 program. Results: Total score for paternal infant attachment in the experimental group was significantly higher than the control group (p<.001). After matching, significant differences were found between the two groups through all subcategories. Adjusted mean score for paternal infant attachment verified experimental effects. Conclusion: Results indicate that this paternal participation program during cesarean section is effective in improving paternal infant attachment.

This study was carried out to investigate the fertility and farrowing date in post-weaning sows using PG600 and inseminated with frozen semen. A total of 48 sows of Landrace, Large White and Duroc after 7-week lactation were used at the Chungnam Provincial Animal Breeding Station. The results obtained were summarized as follows: 1. Motility had no significant differences between the breeds, but NAR acrosome was highest in Landrace, followed by Duroc and Large White(p<.01). 2. Interval from weaning to estrus and length of estrus were, respectively, 3.7 days and 52.6hours of sows treated with PG600, and 6.5 days and 53.8 hours for control sows. The average interval from weaning to onset of estrus was significantly(p<.01) shorter by 2.8 days in PG600 treated sows compared to control sows. 3. In Landrace, Duroc and Large White, farrowing rate and number of pigs born alive per litter were 55.0%, 10.0; 43.8%, 8.1; and 16.7%, 3.5, respectively. Average pig weight at birth and survival rate at 56 days had no significant differences between the breeds. 4. Farrowing rate, number of pigs born alive per litter, average pig weight at birth and survival rate at 56 days were, respectivey, 45.8%, 101, 1.56kg and 94.5% for sows treated with PG600, and 37.5%, 7.0, 1.66kg and 93.8% for control sows. Sows treated with PG 600 had an average of 3.1 more pigs at farrowing compared to control sows.

The aim of the present work was to study the effects of a polyherbal supplement on cross bred does, starting from the last month of pregnancy to weaning, on milk yield, kid birth weight and growth rate. Thirty does were divided into three treatments of ten each in individual pens: low level supplementation (LS), high level supplementation (HS) and non-supplemented treatment (NS) as control. Low supplemented goats were given 125 mg/kg BW/d of polyherbal combination; high supplemented goats were given 250 mg/kg BW/d. The study was carried out in 2008. Fifty-nine kids were born from all the experimental animals. There was no difference on milk yield between supplemented groups and control (p>0.05), although polyherbal supplementation had positive effect on litter birth weight and growth rate compared to control. Weaning weights were higher (p<0.001) in LS and HS compared to NS does. In both supplemented treatments compared to control, mortalities and morbidities were also lower in kids born. It is concluded that pre-partum to weaning supplementation increases kids growth rates and weaning weights, as well as reduces kid mortalities, but it doesn't have significant effect on milk production.

Background: Family planning is widely practiced today to resolve the over-growing population and overcome obstacles that thwart socio-economic growth. While Ghana was the first country in Africa to implement family planning program, its birthrate is still twice as much as world average due to weak infrastructure and strategic plans to enforce the policy. Thus, there is a need to objectively verify the factors that affect family planning of fertile women of Ghana. Methods: Total of 630 self-administered questionnaires were distributed from April 8 to 17 of 2013 to collect data. Six-hundred eighteen questionnaires were analyzed, excluding the 12 incomplete questionnaires. Collected data were analyzed using PASW SPSS ver. 18, and logistic regression analysis was performed to verify the factors that affect practice of family planning. Results: Satisfaction with health and medical facilities, experience with family planning education and awareness of birth control methods significantly affected practice of family planning. Based on analysis using odds ratio, enforcement rate of family planning increased by 4.574 times when the subjects were satisfied with health and medical facilities, by 3.920 times when received family planning education, and by 3.284 times when they were aware of birth control methods. Conclusion: By adopting family planning education program, government should be able to change fertile women's perception of family planning. A strategic plan is necessary in order to increase access to medical facilities, improve service satisfaction, and induce women to enforce family planning voluntarily.

Purpose. The purpose of this study was to evaluate the premature infants' responses to infant massage (tactile and kinesthetic stimulation). These responses measured by weight, physiological (vagal tone, heart rate, oxygen saturation) and behavioral responses (behavioral states, motor activities, and behavioral distress). Methods. This study was conducted using an equivalent control pretest-posttest design. The sample was divided into two groups of 13 infants with gestational age less than 36 weeks at birth, birth weight less than 2000g, and no congenital anomalies. The experimental group received the massage intervention twice daily for 10 days. The data were collected for 10 minutes prior to and 10 minutes after the massage. Results. The vagal tone was significantly higher after massage than before massage in the experimental group, while no change in the control group. The experimental group had significantly higher scores for awake state and motor activity than the control group. Significantly greater awake state, more fidgeting or crying, and increased motor activity were reported after massage than before massage. Conclusions. The results of this study showed that massage therapy might enhance optimal physiological responses and behavioral organization of premature infants. Nursing staff in the NICU can use massage to promote the infant's capability to respond positively to his environment and to provide developmental support for healthy premature infants.

Purpose: This study was conducted to investigate the effects of multimodal sensory stimulation on growth and mother-infant interaction in infants with low birth weight (LBW). Method: A non-equivalent control group time-series study design was used. The participants were 38 LBW infants and their mothers (19 in the intervention group and 19 in the control group). The data were collected from September 1, 2003 to March 31, 2004. For the mothers in the intervention group, this researcher instructed mothers in the multimodal sensory stimulation therapy, in turn the mothers used these techniques on their infants once a day during the 4-week research period. The researcher measured weight, length, and head circumference of the LBW infants once a week for 4 weeks and made a film of the mother playing with the infant for 5 minutes in the last week of the research period. Results: Compared to the control group, LBW infants in the intervention group showed significant increases in weekly weight gain (F=3.82, p=.012) and had significantly higher scores for mother-infant interaction (t=3.93, p>.000). Conclusion: The results suggest that multimodal sensory stimulation therapy can be used to increase the growth of LBW infants and improve mother-infant interaction.
