Abstract:

Le potentiel des plantes connues pour leurs vertus médicinales suscite un grand intérêt dans un contexte mondial de réduction des risques d’antibiorésistance. Dans le cadre de la nutrition animale, l’usage des extraits de plantes se positionne dans une démarche de gestion intégrée de la santé des animaux dans le but de favoriser la construction de leur immunité et de limiter l’apparition des maladies. Le soutien des fonctions immunitaires par l’apport d’extraits de plantes est un moyen de renforcer les capacités d’adaptation des poulets, notamment chez le poussin. Pour mettre en œuvre leur usa

Dans un objectif d’amélioration de la compétitivité, les poulets de chair sont sélectionnés sur leur vitesse de croissance et leur efficacité alimentaire. Ces deux critères ont ainsi été multipliés respectivement par 4 et par 3 en 60 ans. La sélection d’animaux capables d’ingérer une grande quantité d’aliment a permis ces gains de productivité, avec différentes conséquences en termes de bien-être animal car les animaux les plus performants sont aussi le plus souvent les plus fragiles.

Le poulet de chair a connu une amélioration spectaculaire de sa productivité, grâce aux progrès concomitants des méthodes d’élevage, de la nutrition, de la génétique et de la médecine vétérinaire. Ces progrès se sont traduits par une forte réduction de l’âge à l’abattage, principal déterminant de la qualité sensorielle de la viande. Ce critère a été le principal élément de la segmentation qualitative de la filière.

Whereas, leaves of most plants in our agroecological zone contain these nutrients and can be obtained at no cost, it is necessary to utilize them for similar purposes to reduce cost and enhance the wellbeing of the an

Abstract:

An in vitro method was developed to predict inorganic P release from maize-soyabean poultry feeds containing supplemental phytase (EC31·3·8), and to quantify the effect of acid phosphatase (EC 3·1·3·2), fungal protease (EC 3·4·23·6) and Aspergillus niger cellulase (EC 3·2·1·4) on phytate dephosphorylation. Pepsin (EC3·4·23·1) and pancreatin digestion periods were preceded by a 30 min pre-incubation at pH 5·25 to simulate digestion in the crop of poultry. Pancreatin digestion was carried out in dialysis tubing, with a ratio of about 1:25 (v/v) between the digesta and dialysing medium, to simula

Extrusion cooking, a high-temperature short-time processing technique holds promise for lowering enzyme inhibitor activities and improving nutrient bioavailability in grain legumes, thus improving their feeding value. The effect of extrusion cooking of two grain legumes; pigeon pea (Cajanus cajan) and bambara groundnut (Vigna subterranean) at varied temperatures on growth performance, endogenous enzyme activity and organ development of 35d-old meat-type chickens was investigated. Pigeon pea and bambara groundnut were milled and extruded at two temperatures (100 C and 140 C)from which six diets

Abstract:

The high cost of feed has become a great challenge in poultry production. Good quality and cheap feed is therefore crucial for optimal growth performance of poultry chickens. In this study the effect of Euphorbia heterophylla Leaf Meal (EHLM) on the performance, carcass characteristics, nutrients digestibility and economics were evaluated. Broiler chicks numbering one hundred and eighty (180) of Ross 308 strain were fed for 4 weeks. The birds were randomly allotted to six experimental diets with three replications of 10 birds each. The diets were formulated with the inclusion of EHLMat 0, 5, 1

Abstract:

Exogenous proteases are promoted for their ability to counteract the negative effects of antinutritional elements such as trypsin inhibitors in broiler chickens. This is because these anti-nutritional substances are proteinaceous, making them candidates for hydrolysis by proteases. However, there still is insufficient knowledge on the sensitivity of this phenomena to protease dosing, hence this study was designed to evaluate the dose sensitivity of broiler starter chickens fed a high trypsin inhibitor soyabean-based diet supplemented with a mono-component protease.

The CPM was improved by mix-grinding 1000g of it with fresh and succulent leaves CM at 0, 10, 20, 30 and 40% levels, respectively and included in the diets.
