Abstract

We evaluated the effect of inclusion of fine mesquite pod meal (FPM) in the diet on performance, preference and palatability of diets in feedlot lambs. Five diets were formulated with increasing levels of FPM (0, 1.5, 3.0, 4.5 and 6.0%). For performance evaluation, the design was completely randomized with five treatments and seven replications. For palatability and preference analysis, the same design was used, but the treatments consisted of diets with 0 and 3% FPM and fourteen replications. The palatability was assessed considering the amount of feed consumed within 30 min., and the preference, considering the feed intake after 24 hours. FPM had no influence on weight gain, but caused a reduction in intake and an increase in dry matter digestibility for inclusion level above 2.4%. The greatest contribution of FPM inclusion is due to the increase in neutral detergent fiber digestibility. The preference and palatability in feedlot lambs is not affected by the inclusion of 3% FPM.

Highlights

The growing demand for high quality sheep meat increased production of lambs for slaughter, which generated the need to improve production systems to meet the customer requirements (Schönfeldt & Gibson, 2008)
The understanding of the processes of food intake and the intervening factors in animals is of great importance for nutritionists, since these determine the potential amount of nutrients ingested and, according to digestibility, indicate the amount of nutrients available to meet the requirements for maintenance
This study evaluated the effect of inclusion of fine mesquite pod meal in the diet on performance, intake, digestibility, palatability and preference of diets offered to feedlot lambs

Summary

Introduction

The growing demand for high quality sheep meat increased production of lambs for slaughter, which generated the need to improve production systems to meet the customer requirements (Schönfeldt & Gibson, 2008). The fine mesquite pod meal is a byproduct derived from the processing of mesquite pods This is a low density ingredient, in the form of yellowish powder and has excellent binder and flavoring characteristics probably because it consists of readily available carbohydrate, but, this characteristic has not yet been properly studied. In this way, this study evaluated the effect of inclusion of fine mesquite pod meal in the diet on performance, intake, digestibility, palatability and preference of diets offered to feedlot lambs
