Prevalence Of Anemia

Author has studied the average birth weight using the birth register from Syktyvkar and Vorkuta of Komi Republic. The prevalence of anemia was higher in Vorkuta. Infants born to woman with anemia were heavier than infants of non-anemic mothers were (Sykvyvkar, р<0,001). Babies of anemic mothers from the third or more deliveries were heavier than from the first deliveries (Vorkuta, p<0,001).

Natural Service

SUMMARYGilts were allocated at 55 kg live weight to one of three treatments: 1. 1·4 kg of food daily to service, served at puberty, and 1·4 kg of food daily throughout pregnancy.2. 1·4 kg of food daily to service, served at the third heat, and 1·4 kg of food daily during pregnancy.3. 2·3 kg of food daily to service, served at the third heat, and 1·4 kg of food daily during pregnancy.An attempt was made to encourage early puberty by stimulation using the presence of a boar. Natural service with boars was used on all gilts.There were no significant differences between the treatments in time taken to reach puberty and the gilts were mated at 77, 97 and 116 kg live weight on Treatments 1, 2, and 3 respectively. The gilts on Treatment 1 had a significantly lower conception rate and a significantly smaller litter size than those on Treatments 2 and 3. However, the average birth weight did not vary significantly among treatments.

Reproductive Characters

The aim of the experiment was to analyse reproductive characters in hybrid pig combination (CLW x CL) x (D x Pn). These reproductive traits of sows were studied: number of all, live born and weaned piglets, loses from live born piglets till weaning. These influences with an impact on reproductive characters were monitored: order of litter, number of piglets in a litter, birth weight of piglets, influences of sex and litter order on birth weight of piglets. An average number of all born piglets per sow and litter it was 13.25 piglets. From this an average number of live born piglets it was 12.48 piglets per sow and litter and from each litter there was 11.40 of weaned piglets. The highest number of live born piglets was reached in sows on the fourth litter – 14.50 piglets. On eighth and nineth litter fertility decreased to 11.60 and 11.00 piglets. Statistical conclusive difference (P ≤ 0.05) was found between fourth (14.50) and nineth (11.00) litter. Among birth weight in both sexes a statistical conclusive difference (P ≤ 0.05) was found. Higher birth weight (1.46 kg) was found in boars in comparison with gilts (1.40 kg). The highest birth weights in gilts were reached in litters of sows on the second and nineth litters – 1.49 kg and 1.48 kg. Birth weight decreased on tenth litter with average weight of 1.28 kg. The highest birth weight in boars was detected on the seventh litter but on the seventh litter piglets of only one sow were weightened so the result 1.67 kg is not objective. The second highest average birth weight was reached on the third litters – 1.53 kg. On the contrary the lowest average birth weight was on the fourth and tenth litters where boars reached weight of 1.28 and 1.25 kg. Statistical conclusive difference (P ≤ 0.05) was found between the second (1.53 kg) and tenth (1.25 kg) litter.

Reproductive Characters

The aim of the study was to evaluate influences which affect reproductive characters of sows in chosen reproductive breeding. These reproductive traits of sows were studied: number of all, live born and weaned piglets, losses from live born piglets till weaning. These influences which affect reproductive characters were studied: order of litter, number of piglets in litter, birth weight of piglets and influence of sex on birth weight of piglets. An average number of all born piglets per litter it was 11.74 animals. From that 11.33 live born piglets per sow and litter. 10.15 piglets were weaned from each litter in average. It represents 11.68 % of losses in live born piglets till weaning. An influence of litter order on number of live born piglets in litter was studied in an experiment. The first litters show 11.36 of live born piglets in average, the second litters 10.38 piglets, the third litters 10.43 piglets and the fourth litters 10.75 piglets. Maximum was reached on fifth litter with 13.33 of live born piglets. From the sixth litter number of live born piglets was decreasing. On the sixth litter it was 12.33 piglets, on the seventh only 9.40 of live born piglets. Between fifth litter (13.33 piglets) and seventh litter (9.40 piglets) statistical conclusive difference (P ≤ 0.05) was found. The sixth litters showed the highest number of weaned piglets – 11.00. On the contrary the lowest number of weaned piglets it was on the seventh litter – 8.40 piglets. Statistical conclusive difference among the numbers of weaned piglets according to litter order it was not proved. Higher average birth weight (1.50 kg) was found in boars in comparison to gilts (1.46 kg). Next birth weight of gilts and boars was studied in dep endence on litter order. The lowest birth weight in both sexes was found on the first litters – gilts (1.27 kg) and boars (1.36 kg). Gilts reached the highest birth weights on the seconds and the sixths litters (1.62 kg). Statistical conclusive difference (P ≤ 0.05) was found in gilts among litters one (1.27 kg) and two (1.62 kg) respectively six (1.62 kg). Boars reached the lowest birth weight (1.36 kg) on the first litter. The highest birth weight of boars (1.73 kg) was reached on the fourth litter. Statistical conclusive difference (P ≤ 0.05) was found among these litters. Next statistical conclusive difference (P ≤ 0.05) was found between the first (1.36) and sixth (1.70 kg) litter and statistical conclusive difference (P ≤ 0.01) between the first and the second litter (1.68 kg).

Avon Longitudinal Study

Abstract Background Evidence suggests that exposure to particulate matter with aerodynamic diameter less than 10 μm (PM10) is associated with reduced birth weight, but information is limited on the sources of PM10 and exposure misclassification from assigning exposures to place of residence at birth. Methods Trimester and source-specific PM10 exposures (PM10 from road source, local non-road source, and total source) in pregnancy were estimated using dispersion models and a full maternal residential history for 12,020 births from the Avon longitudinal study of parents and children (ALSPAC) cohort in 1990–1992 in the Bristol area. Information on birth outcomes were obtained from birth records. Maternal sociodemographic and lifestyle factors were obtained from questionnaires. We used linear regression models for continuous outcomes (birth weight, head circumference (HC), and birth length (BL) and logistic regression models for binary outcomes (preterm birth (PTB), term low birth weight (TLBW) and small for gestational age (SGA)). Sensitivity analysis was performed using multiple imputation for missing covariate data. Results After adjustment, interquartile range increases in source specific PM10 from traffic were associated with 17 to 18% increased odds of TLBW in all pregnancy periods. We also found odds of TLBW increased by 40% (OR: 1.40, 95%CI: 1.12, 1.75) and odds of SGA increased by 18% (OR: 1.18, 95%CI: 1.05, 1.32) per IQR (6.54 μg/m3) increase of total PM10 exposure in the third trimester. Conclusion This study adds to evidence that maternal PM10 exposures affect birth weight, with particular concern in relation to exposures to PM10 from road transport sources; results for total PM10 suggest greatest effect in the third trimester. Effect size estimates relate to exposures in the 1990s and are higher than those for recent studies – this may relate to reduced exposure misclassification through use of full residential history information, changes in air pollution toxicity over time and/or residual confounding.

Zinc Levels

Background: According to 2018 World Health Organization (WHO) data globally, an estimated 17.3% of the population has inadequate zinc intake, with estimates ranging from 5.7% in Oceania to 7.6% in Europe, 9.6% in America and the Caribbean, highest in Africa (23.9%) and Asia (19.6%). Zinc is important for the function of a number of enzymes and growth hormones during pregnancy. In pregnant women, the relative zinc concentration decreases up to 35% due to the influence of hormonal changes and the transport of nutrients from mother to baby. Objectives: The purpose of this study was to identify the effect of giving zinc tablets to pregnant women with zinc deficiency in the third trimester on body weight and length of babies born at the Makassar City Health Center. Methods: This type of research is True Experimental with a pretest-posttest design with a control group. The sample in this study was 62 samples of third trimester pregnant women, and the sampling technique used was purposive sampling. Measurement of zinc levels in third trimester pregnant women using the Elisa reader kit at the Research Laboratory of the Hasanuddin University Teaching Hospital. The research instruments were in the form of a research explanation sheet, respondent's consent sheet, respondent's checklist sheet, and the mother's zinc tablet consumption control sheet for 14 days. Results: Judging from the average value of newborns in pregnant women who did not have zinc deficiency, the average value of birth weight in pregnant women with zinc deficiency was 15.70 g/dL and 18.95 g/dL. zinc deficiency with a value (p < 0.05), while pregnant women with zinc deficiency have an average birth length of 10.00 g/dL and mothers who do not have a deficiency of 19.87 g/dL with a value (p < 0.05). So, it can be concluded that giving zinc tablets to pregnant women in the third trimester has an effect on Birth Weight (BBL) and Birth Length (PBL). Conclusion: Giving zinc tablets has an effect on increasing zinc levels in third trimester zinc deficiency pregnant women and increasing birth weight and length of the baby.

Objective: To determine the relationship between serum zinc level at term pregnancy and newborn anthropometry. Methods: This study is an observational study with cross-sectional design. Serum zinc level at term pregnancy was measured and then anthropometric measurement was done to the newborn, including birth weight, birth length and head circumference at birth. The data were statistically analyzed using regression correlation test. Results: Mean serum zinc level at term pregnancy is 36.01 μg/dl (SD=18.34 μg/dl), the average birth weight is 3158 gr (SD=480.4 gr), the average birth length is 48.42 cm (SD=1.75 cm) and the average head circumference at birth is 33.13 cm (SD=1.14 cm). There was no statistically significant relationship between serum zinc levels at term pregnancy and birth weight (p-value=0.152). Meanwhile, there are statistically significant relationships between serum zinc level at term pregnancy with birth length and head circumference with pvalue 0.026 and 0.012, respectively. Conclusion: Serum zinc level at term pregnancy is correlated with birth length and head circumference, but is not correlated with birth weight.

Birth Characteristics

The Åland Islands were recently ranked as Finland’s healthiest region with lower prevalence of several non-communicable diseases compared with the national mean. We have compared birth characteristics of 1697 individuals born on the Åland Islands between 1937 and 1944 with contemporaneous data from the Helsinki Birth Cohort Study (HBCS;n=11,808). This is a first step towards a potential future analysis of Ålandic health from a life-course perspective. Mean birth weight and length were calculated for both cohorts. Birth weight was entered into a multiple linear regression model with sex, maternal age, marital status and birth year as predictors. Mean birth weight in the Åland cohort was 3499 g, 87 g (95% CI 62; 111) higher compared with the HBCS. Sex and maternal marital status were the strongest predictors of birth weight. More detailed studies are needed to explore the potential effects of this difference in average birth weight between cohorts.

Four Levels

For 4 consecutive years, calf production was compared for Shorthorn cows fed at four levels during winter pregnancy and barn-nursing: (I) ad libitum corn silage plus 1.0 kg mixed hay/100 kg initial body weight daily; (II), (III) and (IV) approximately 80, 60 and 40%, respectively, of level-I intake. Half of the cows on each level received 0.45 kg linseed oilmeal (LOM) per head, daily, and half of both the LOM and no-LOM cows received supplemental vitamin A (84,000 IU per head, weekly).Neither the 4-year average birth weight (32.8, 32.3, 34.8, 32.4 kg for levels I to IV, respectively) nor the 4-year average daily gain to weaning (0.85, 0.89, 0.89, 0.89 kg for levels I to IV, respectively) were significantly different (P > 0.05). The 4-year average wither height and body depth at birth were similarly not different for the four levels. Supplementing the dam’s ration with LOM and/or vitamin A had no significant (P > 0.05) effect on either weight and body measurements at birth or gain to weaning. It was only during year 3, when level-IV cows’ (non-LOM-supplemented) daily intake was 0.033 kg digestible protein and 0.36 kg total digestible nutrients per 100 kg initial weight, that protein supplementation significantly (P < 0.05) increased birth weight and body measurements of their calves. There was little difference in survival of calves from cows fed at different levels or fed LOM versus no LOM. Contrary to expectations, vitamin A-supplemented cows appeared to produce calves with poorer survival.
