Dwarf broiler breeders in single-bird cages (DC), in floor pens (DF) and normal broiler breeders in floor pens (NF) were compared for their own and their offspring’s performance. No differences were observed in rate of egg production at 147–329 days of age between the NF and DF birds (48 vs. 47%) whereas the DC birds laid at the rate of 40%. Hen-housed egg numbers for the same period followed the same general pattern (NF, 81; DF, 82; DC, 70 eggs/bird). DF and DC birds consumed less feed per dozen eggs than the NF birds (3.4 vs. 4.3 kg/doz). Egg weights in the early part of the production cycle were not significantly different among the groups but at 294 days of age the normal birds laid larger eggs than the dwarfs (65 vs. 62 g). Dwarfs in cages reached 50% production earlier than the DF or NF birds. Female offspring from the three groups grew at the same rate and weighed 1.7 kg at 56 days of age but there were significant differences in feed conversion (NF, 2.46; DF, 2.43; DC, 2.53 kg/kg body weight produced). Male offspring had small but not statistically significant differences in body weight at 56 days (NF, 2.16; DF, 2.12; DC, 2.09 kg) or feed conversion (NF, 2.30; DF, 2.29; DC, 2.34 kg/kg body weight). Mortality in the offspring ranged from 2.7 to 9.2% but did not differ significantly. Income over feed costs per broiler started did not differ from the three groups regardless of the meat price – feed price combination considered. However, when profit was computed on a breeder hen basis, the DF females were more profitable than either the NF or DC females.

<p>Oxidative stress is related to pregnancy complications that could increase maternal and infant mortality. This study aimed to determine the effect of propolis extract supplementation during pregnancy on oxidative stress level and pregnancy outcomes utilizing Malonedealdehyde (MDA) and 8-Oxo-2′-Deoxogunosine (8-OHdG) levels, maternal body weight, and the average number of fetuses as the parameters. The study was conducted by using a posttest only control group design on 24 pregnant Wistar rats, which were divided into four groups. Group I was control, Group II-IV were the treatment groups given propolis extract of 1.8mg, 3.6mg, and 7.2mg/200gBW/day, respectively. The standard feed given was AIN93G dose of 20g/day and distilled water ad libitum. Propolis extract was given using a gastric feeding tube every morning for 20 days. At the end of the treatment, body weight was meisured and blood collected for assessed MDA and 8-OHdG levels  by ELISA method  and then we performed abdominal surgery to count number of fetuses. The result are there were decreasing level of MDA and 8-OHDG by administration of propolis significantly (p&lt;0.05) group: I: 2,04±0,091, II: 1,55±0,067, III: 1,05±0,176, IV: 0,73±0,075 (mmol/mL) (p=0.001); 8 OHdG level (ng/mL) group I: 10,02±0,403, II: 8,60±0,078, III: 7,89±0,051, IV: 7,53±0,063 (p=0,001). Average of maternal body weight (g) were increased: group I: 228,33±3,93, II: 237,17±4,36, III: 244,83±4,02, IV: 248,00±5,76 (p=0,001) and Average number of fetuses tend to increased as well, group I : 8,5±0,05, II: 7,8±0,41, III: 9,5±1,05, IV: 9,6±0,52 (p=0,02). The conclusion of this research are supplementation of propolis extract in pregnant rats can reduce oxidative stress and improve pregnancy outcomes.</p>

ObjectivesThe present study aimed to estimate the prevalence of low birth weight (LBW), and to investigate the association between maternal body weight measured in terms of body mass index (BMI) and birth weight in selected countries in Africa.SettingUrban and rural household in Burkina Faso, Ghana, Malawi, Senegal and Uganda.ParticipantsMothers (n=11 418) aged between 15 and 49 years with a history of childbirth in the last 5 years.ResultsThe prevalence of LBW in Burkina Faso, Ghana, Malawi, Senegal and Uganda was, respectively, 13.4%, 10.2%, 12.1%, 15.7% and 10%. Compared with women who are of normal weight, underweight mothers had a higher likelihood of giving birth to LBW babies in all countries except Ghana. However, the association between maternal BMI and birth weight was found to be statistically significant for Senegal only (OR=1.961 (95% CI 1.259 to 3.055)).ConclusionUnderweight mothers in Senegal share a greater risk of having LBW babies compared with their normal-weight counterparts. Programmes targeting to address infant mortality should focus on promoting nutritional status among women of childbearing age. Longitudinal studies are required to better elucidate the causal nature of the relationship between maternal underweight and LBW.
