Abstract

The intake of the dry matter (DM), the crude protein (CP) and the metabolizable energy intake (ME) in megacalories per day (Mcal/day) were not affected by the diets. In contrast, the intake of neutral detergent fiber (NDF), in g/kg BW, increased linearly. An increasing linear effect was also observed for the ether extract (EE) intake, whereas a decreasing linear performance was observed for the non-fibrous carbohydrate (NFC) intake. The digestibility of DM, organic matter and NFC decreased linearly with the sunflower cake inclusion, whereas the digestibility of CP, NDF, and EE were not influenced by the diets. No effect was observed for the concentration of serum glucose or urea nitrogen serum. No effect was observed on the urea nitrogen serum in the hours after feeding; however, including sunflower cake in the diets resulted in a quadratic performance for the serum glucose concentrations in the hours after feeding. The average daily gain (ADG) had a decreasing linear effect, and the food conversions of the DM, CP, NDF, NFC and ME had increasing linear effects. The feeding costs decreased with the level of sunflower cake.

Highlights

Goat farming in the Northeast of Brazil has an important socio-economic role and is mainly focused on meat and milk production
An increasing linear effect was observed for the ether extract (EE) intake, whereas a decreasing linear performance was observed for the non-fibrous carbohydrate (NFC) intake
The dry matter intake was not influenced by the inclusion of the sunflower cake in the diets (Table 4), even with the increase in the neutral detergent fiber percentage in the diets (Table 3)

Summary

Introduction

Goat farming in the Northeast of Brazil has an important socio-economic role and is mainly focused on meat and milk production These products are an important nutritional and income source, especially for small producers (Simplício, 2003). Producers are faced with limitations in obtaining feed for the animals that is rich in protein and energy, especially during the dry season, when the supply of forage is scarce, resulting in low animal performance (Dantas Filho, 2007). To overcome this adversity, producers make use of concentrated feeds, which are expensive. The present study was conducted to evaluate the inclusion of sunflower cake from the biodiesel production in the diet of crossbred Boer kids through the study of productive performance, apparent digestibility, blood parameters and feeding costs
