Replacement of corn with mango meal for dairy goats

Abstract

SummaryBackground: the high volume of mangos harvested during the season, associated with inappropriate management of the fruit after harvesting results in increased waste of this valuable resource. Mango fruit, rich in carbohydrates, has potential use in animal feeding. Objective: to evaluate the effect of replacing corn with whole mango meal (0, 330, 660, and 1000 g/Kg on dry matter basis) in the diets of dairy goats on rumen fermentation kinetics, intake, milk yield and composition, and economic results. Methods: eight lactating Saanen crossbred goats (48.7 ± 1.99 Kg body weight) were used in the experiment, which started 48 days postpartum and lasted until completing 124 days of lactation. The experimental design consisted of a double Latin square (4×4) with four treatments, four periods and four animals per square. Results: a reduction (p<0.05) was observed in gas production from total carbohydrates and fiber carbohydrates. Replacement of corn with whole mango meal showed no effect on DM intake (1,890 g/d), crude protein (278 g/d) and neutral

Utilization of Avocado and Mango Fruit Wastes in Multi-Nutrient Blocks for Goats Feeding: In Vitro Evaluation

“…The effects of feeding MB including avocado wastes to goats on milk yield and composition have been recently studied [10], but to our best knowledge, there is no information on the possibility of including mango wastes in MB. However, several studies have investigated the direct feeding of mango wastes to ruminants [11][12][13] and non-ruminants [14,15], indicating that they can be used as alternative feeds [16]. The aim of this study was therefore to assess the chemical composition and in vitro ruminal fermentation of two type of wastes from avocado and mango, peels and a mixture of pulp and peels (PP), and to analyze the in vitro ruminal fermentation of MB including PP wastes of each fruit.…”
