The research has been accomplished in the Department of Anatomy and Physiology of the Lithuanian Veterinary Academy, in the Research Center of Digestive Physiology and Pathology and in the Center of Practical Training and Experiments of the Lithuanian Veterinary Academy in 2005 - 2007. The study consists of 50 pages. There are 3 tables, 13 pictures and 5 appendixes presented in it. In order to achieve high cattle productivity it is very important to establish optimal conditions for neonate calves breeding, to stimulate development of digestive tract and activate development of useful microflora, especially on the first month of calves breeding. The purpose of this work was to determine the influence of probiotic “Yeasture” to growth, wellness and microflora of the digestive tract of neonate calves, feeding probiotic to the calves on the first month of age. The experiment has been accomplished on Lithuanian-White neonate calves throughout the indoor period from November to January. Two groups of neonate calves were organized: control group (n=8) and experimental group (n=8). Calves of the experimental group were made to drink a preventive dose of the probiotic “Yeasture” every day, id est 5 g per day according to recommendations of the manufacturer. When the neonate calves were fed with the probiotic “Yeasture” supplement for the first month of age, their daily overweight had increased averagely by 16.1 percent. Probiotic “Yeasture” had no influence to daily overweight on the... [to full text]

Mechanically pressed Brassica napus L. meals’ digestibility nutritional compositions were evaluated with digestibility studies. Two growth trials were conducted identifying the meals’ maximum dietary inclusion level in broiler chicken diets. Heat reduced nutrient digestibility of mechanically pressed black canola meal (MPBCM). Meals with higher residual oil had higher AMEn. Enzyme addition did not affect MPBCM AMEn but increased standardized ileal amino acid digestibility (SIAAD) of meal with high residual oil. Carbohydrase increased AMEn of mechanically pressed yellow canola meal (MPYCM) while lipase generally improved SIAAD. MPBCM with 12 and 17% residual oil can be fed up 15% in the starter and grower diets but at 10% in finisher diet. Mechanically pressed black canola meal (MPYCM) with 12% residual oil should be fed in the starter and finisher diets at 10% and 15% in grower diet. Meal with 17% residual oil should be fed only at 10% in finisher diet. / Masters Thesis

The interrelation among maternal dietary intake, pregravid weight, amount and pattern of gestational weight gain and cigarette smoking in influencing the balance between fetal growth and maternal postpartum weight retention was in investigated in 1,330 healthy participants in the PEI Nutritional Counselling Program. Among nonsmokers, gestational weight gain was the main predictor of postpartum weight retention and explained 65.3% of its variability, while explaining only 4.7% of infant birth weight variability. Women with higher postpartum weight retention gained more weight during pregnancy and most of the difference between higher and lower weight retention groups occurred in the first 20 weeks. When comparing infant size between smoking and nonsmoking mothers, birth weight increased linearly with maternal weight gain in all weight status groups except in overweight nonsmokers where birth weight reached a plateau at weight gains $>$17 kg. Among smokers, infant length increased at a higher rate with weight gain than nonsmokers. Although higher weight gains seemed to partially mitigate the effect of smoking on the risk of small-for-gestational-age (SGA) infants, such risk remained $>$10% at elevated weight gains among underweight smokers. The effects of smoking in reducing maternal and infant weights were not mediated by lower energy intake, as smokers consumed more energy than nonsmokers after controlling for physical activity and pregravid weight. The independent relative risks of SGA infants due to maternal smoking, pregravid underweight and low weight gain, were 3.23, 1.80 and 1.72 respectively, implying that smoking has the greatest effect on SGA. Based on current smoking prevalence in Canada, the population etiologic fraction of SGA due to the direct effect of smoking is 30.8%; approximately twice that for maternal underweight or low weight gain. Efforts to increase infant birth weight through higher maternal weight gain would require impractically high ene

The purpose of this study was to determine the relationship- between prenatal weight gain relative to initial weight and change in smoking habits relative to prepregnancy smoking habits on infant birth weight. The convenience sample was 100 women who had been prenatal clients at a clinic for low income women and who delivered term infants during a one year period. Women were selected who had term deliveries and were without medical problems during the pregnancy.Prepregnancy weight-for-height was determined using the 1959 Metropolitan Life Insurance Table. Weight gain throughout the pregnancy was charted on the appropriate graph. Changes in smoking habits during the pregnancy were evaluated verbally. Roy's Adaptation Model was the conceptual framework for this study. The physiological mode of this model depicts people as individuals who are constantly adapting to a changing environment. Procedures for the protection of human subjects were followed.The first research question illustrated that women who gained adequate weight and reduced or quit smoking had infants with higher birth weights. The second research question showed that, overall, women who quit or reduced the amount smoked early in pregnancy had infants with higher birth weights than women who quit or reduced later in pregnancy or-who did not change smoking habits. The third research question determined that nonsmokers had infants with higher birth weights than smokers.Women who smoke will have infants with lower birth weights than those that do not smoke. Women with inadequate weight gains during pregnancy are more likely to have infants: with lower birth weights than women with adequate weight gains. Health care providers must be able to relay, the risks of inadequate weight gain and smoking to pregnant women. / School of Nursing

The purpose of this study was to examine maternal and infant factors associated with body mass index (e.g., maternal weight gain, infant birth weight, infant feeding methods, and motor coordination) among obese pre-adolescents and adolescents aged 8-18 years enrolled in the Pediatric OverWeight Education and Research (POWER) program operated by Riley Hospital for Children in Indianapolis, IN, between October 2008 and September 2011. POWER, a three-phase, 12-month multi-disciplinary program to reduce childhood obesity funded by Indiana University Health, enrolls obese children (Body Mass Index [BMI] greater than the 95th percentile for age and gender) through referrals from pediatricians throughout Indiana. Prior to the child’s initial visit, each family completes a comprehensive background and family history profile, approved by the Indiana University-Purdue University (IUPUI) Institutional Review Board, that includes questions related to the obese child’s motor skill development, infant feeding methods, maternal prenatal weight gain, and infant birth weight. Data related to these four categories collected during Phase 1 (12 weeks) was examined using date from 253 pre-adolescents (8-12 years of age), and 285 adolescents (13-18 years of age), to determine their impact on the subjects’ BMI. No relationship between a mother’s prenatal weight gain and the child’s BMI was seen. There was a significant correlation between infant birth weight and BMI in the pre-adolescent group. Breastfed subjects entered the POWER program at a lower BMI than non-breast fed subjects and had consistently lower BMIs throughout the program compared to the non-breastfed subjects. Differences in physical activity were observed between adolescents and pre-adolescents. Paired analysis indicated the POWER program was associated with a significant reduction in BMI overall, and among both age groups throughout Phase 1 of the program. Adolescents were especially successful in reducing their BMI compared to preadolescents. Further research is needed to identify the association of maternal and infant factors and BMI among obese children. / Department of Family and Consumer Sciences
