Use of multivitamin, acidifier and Azolla in the diet of broiler chickens

Effect of varying dietary Azolla levels on growth, carcass characteristics, blood biochemical parameters and digestive enzymes of growing Egyptian geese

The present study was performed to determine the influence of dietary levels of Azolla on growth performance, blood parameters and digestive enzymes of growing geese. At 4 weeks old, 120 Egyptian goslings were randomly distributed to 4 groups, 30 to each group. Geese were fed four levels of Azolla (0, 4, 8 and 16%) during the experimental period (4-12 weeks of age). No significant differences were noticed among the experimental groups on growth parameters except body weight gain (BWG) during 4-8 wk of age and feed intake (FI) at 8-12 wk of age. Plasma total protein (TP), globulin, total cholesterol (TC) and low density lipoprotein (LDL) levels were significantly increased by 8% Azolla level. However, urea level was significantly decreased in geese fed on 8% and 16% Azolla levels compared to 4% level and control group. Super oxide dismutase (SOD), reduced glutathione (GSH), catalase (CAT), immunoglobulin (IgG), and lysozyme were significantly reduced by all dietary Azolla levels supplementation. Digestive enzymes were statistically affected by Azolla levels. It can be concluded that use of Azolla in Egyptian geese diets at 8 and 16% achieved positive effects on growth performance and most of blood biochemical parameters during the fattening period.

Willingness to Pay for Safe Chicken Meat in Bangladesh: A Contingent Valuation Approach

The poultry meat industry is primarily dominated by broilers, and conventional broiler meat is claimed to be malicious to human health and environment since it is produced using hazardous feeds and other dietary supplements. This study aimed to evaluate consumers’ willingness to pay (WTP) for safe broiler chicken meat following a contingent valuation model (CVM). Also, consumers’ consumption and different types of perceptions on safe broiler meat were assessed from the data collected among 300 consumers in Bangladesh. Consumers’ health and environmental perception of safe broiler meat are found to be high, indicating that they are more concerned about these attributes in the case of consuming broiler meat. The results reveal that conventional broiler meat losses its appeal to consumers after a certain income level and is mainly consumed by lower- and middle-income groups. This study divulges a unanimous demand for safe broiler meat among the consumers who intend to consume about 36% higher than their present consumption level if the availability was ensured in their local market. The average WTP premium for safe broiler meat is estimated to be about BDT 39.87 per kg. The consumers’ WTP is positively influenced by their education, income level, the current consumption of broiler chicken meat, health perception, and taste and nutrition perception. This study recommends meat producers, entrepreneurs, and farmers adjust their production and marketing plans by incorporating suitable quality control procedures to meet the unfilled consumer demand for safer broiler meat. Besides, slow-growing safer broiler chicken needs to be introduced to improve meat’s taste and nutritional aspects.
