Evaluation des Doses Variables du Miel Local de Apis Mellifera Adansonii Latr. 1789 dans les Rations des Poulets de Chair

Le miel est un produit renfermant des propriétés nutritives susceptibles de stimuler les performances zootechniques des volailles. L’objectif de cette étude était de déterminer le taux d’incorporation optimal du miel dans les rations des poulets de chair. Un échantillon de 105 poussins de chair a été  réparti en trois lots de 35 sujets et chaque lot  subdivisé en 5  répétitions   de 7 sujets. Les lots traités 1 et le traité 2 ont reçu des doses du miel dans la ration alimentaire respectivement au démarrage 0,5% et 1%, en croissance 1% et 2% et en finition 1% et 4%. Le premier lot a servi de témoin. Les lots ont été comparés sur les variables de croissance pondérale.   Les résultats ont  montré au cours de la phase de démarrage une amélioration significative (P < 0,05) sur la consommation volontaire des aliments (30,5g contre 34,8g), du GMQ (22,7 g/jour contre 23,4g/ jour), l’IC (1,3 contre 1,4)et le poids vif  à 14 jours (359g contre 377g).Par contre au cours de là phase de croissance, aucune différence significative n’a été notée dans la ration contenant 1% de miel. En revanche pendant la phase de finition, une amélioration significative a été observée sur tous les paramètres étudiés. Cette étude suggère l’utilisation du miel à la dose de 0,5% pendant les phases de démarrage et de croissance et à 1% au cours de la phase de finition.   Honey is a natural bee product containing nutritional properties able to stimulate the performance of poultry. The study aimed to determine the optimal rate of honey in the rations of broiler. A sample of 105 chicks has been randomized and then divided into three groups of 35 chicks each (One control and two treated groups). Then each group was then divided in 5 replicates of 7 chicks. The treated groups received doses of honey at the starting 0.5% and 1%, in growing 1% and 2% finally in finishing stage 1% and 4% respectively. Groups were compared on the growth parameters. The results showed that during the starting stage, a significant improvement (P < 0.05) was observed on feed intake (30.5g vs 34.8g), DWG (22.7g per day vs 23.4g per day), feed efficiency (1.3 vs 1.4) and body live weight (359 vs 377g at 14 days). However, during the growing stage, no significant difference was observed on feed containing 1% of honey. Moreover, during the finishing stage, all the studied parameters were improved by honey at 1%.Therefore, the present study indicated the useful of honey at 0.5% during the starting and growing stages while 1% may be used during the finishing stage

Evaluation of cassava hybrids performance obtained by controlled pollination of elite accessions from Niari landscape in the Republic of Congo

Open Access Journal; Published online: 03 May 2018Cassava is the main crop in the Congo but its low yield doesn’t meet the needs of Congolese populations. The low yield is due to the use of less effective sensitive varieties to diseases, non-mastering of techniques and biotic constraint of which the African cassava mosaic. This study aims at selecting resistant genotypes to the African cassava mosaic and assessing their agronomic and production performances. Six elite accessions selected based on a villager participative approach have been crossed by controlled pollination with three clones (192/0401, 192/0325 and 197/0162) distributed by the International Institute for Tropical Agriculture (IITA). Growth, agronomic and production parameters of genotypes from the controlled pollination were evaluated at the station. Of the ten tested genotypes, the one resulting from the crossing (Mahabama x I92/0401) did not show any symptom of the cassava mosaic disease 12 months after planting. Apart from the root length, foliar surface and the height of the plant, this genotype differed from the others only by the biomass, the diameter of the stem, the harvest index, the rate of starch, the rate of dry matter and marketable or non-marketable tuberous roots. The genotype (Mahabama x I92/0401) will be included in the cassava improvement section plan in the Republic of Congo

Effects of supplementary feeding on the growth performance of late-weaning piglets in tropical areas

Supplementary feeding of piglets in the maternity ward is essential for late weaning at 45 days. The objective of this study was to test the hypothesis that a solid diet could improve the zootechnical performance of piglets at weaning. Thirty-six piglets were divided between three sows: suckling piglets only fed milk by sow A (group 1, control); suckling piglets fed by sow B and receiving the starter feed between days 30–45 (group 2); suckling piglets fed by sow C and receiving both types of feed, prestarter at day 15 and starter at day 30 until day 45 (group 3). Individual weighing was carried out as soon as the prestarter feed was introduced on day 15, then on day 30, finally on day 45. At weaning, piglets fed both types of feed had higher (p < 0.05) live weights at 45 days of age (11.2 ± 2.5 kg vs 8.0 ± 1.7 kg), feed intakes (292 ± 45 g/d vs 134 ± 45 g/d) and average daily weight gains (206 ± 49 g/d vs 101± 30 g/d). In conclusion, solid feed significantly improved (p < 0.05) the feed intakes and growth rates of piglets by day 45. This study showed the need to distribute prestarter and starter feeds in farms enhancing late weaning. This practice opens up prospects for improving animal production performance in pig farming in tropical areas

Effects of hospital facilities on patient outcomes after cancer surgery: an international, prospective, observational study

Background Early death after cancer surgery is higher in low-income and middle-income countries (LMICs) compared with in high-income countries, yet the impact of facility characteristics on early postoperative outcomes is unknown. The aim of this study was to examine the association between hospital infrastructure, resource availability, and processes on early outcomes after cancer surgery worldwide.Methods A multimethods analysis was performed as part of the GlobalSurg 3 study-a multicentre, international, prospective cohort study of patients who had surgery for breast, colorectal, or gastric cancer. The primary outcomes were 30-day mortality and 30-day major complication rates. Potentially beneficial hospital facilities were identified by variable selection to select those associated with 30-day mortality. Adjusted outcomes were determined using generalised estimating equations to account for patient characteristics and country-income group, with population stratification by hospital.Findings Between April 1, 2018, and April 23, 2019, facility-level data were collected for 9685 patients across 238 hospitals in 66 countries (91 hospitals in 20 high-income countries; 57 hospitals in 19 upper-middle-income countries; and 90 hospitals in 27 low-income to lower-middle-income countries). The availability of five hospital facilities was inversely associated with mortality: ultrasound, CT scanner, critical care unit, opioid analgesia, and oncologist. After adjustment for case-mix and country income group, hospitals with three or fewer of these facilities (62 hospitals, 1294 patients) had higher mortality compared with those with four or five (adjusted odds ratio [OR] 3.85 [95% CI 2.58-5.75]; p&lt;0.0001), with excess mortality predominantly explained by a limited capacity to rescue following the development of major complications (63.0% vs 82.7%; OR 0.35 [0.23-0.53]; p&lt;0.0001). Across LMICs, improvements in hospital facilities would prevent one to three deaths for every 100 patients undergoing surgery for cancer.Interpretation Hospitals with higher levels of infrastructure and resources have better outcomes after cancer surgery, independent of country income. Without urgent strengthening of hospital infrastructure and resources, the reductions in cancer-associated mortality associated with improved access will not be realised
