Effect of Increasing Supplementation Levels of Coffee Pulp on Milk Yield and Food Intake in Dual-Purpose Cows: An Alternative Feed Byproduct for Smallholder Dairy Systems of Tropical Climate Regions
Se presenta el artĂculo en texto completoCoffee is one of the main traded commodities worldwide, unfortunately, it generates
massive amounts of by-products like coffee pulp (CoP), which could be utilized as an alternative
feedstuff for cattle contributing to mitigate coffee production environmental damage. The objective of
this work was to evaluate the effect of increasing levels of CoP supplementation on milk production,
milk composition, and grass dry matter intake (GDMI) by dual-purpose tropical cows. A 4 Ă— 4
Latin square experimental design was conducted, where four multiparous dual-purpose Holstein x
Cebu cows with an average live weight of 477 ± 7 kg and milk yield of 12.1 ± 2.7 kg/d were used.
The cows grazed 10 h/d on a Cynodon plectostachius sward with a stocking rate of three cows/ha.
All cows received 6 kg/d DM of an experimental concentrate (EC), and the treatments consisted of
four supplementation levels of CoP: T1 = 0, T2 = 0.6, T3 = 0.9, and T4 = 1.2 kg DM/d, which was
provided on top of the concentrate and mixed with the EC. Grass intake was determined by the
n-alkanes technique. A significant difference was observed for the average total daily DM intake
(p 0.05) were observed for milk yield, milk composition,
body weight, and GDMI for all the inclusion levels of CoP. It was concluded that CoP can be included
at levels of 0.6 to 0.9 kg DM/d in the diets of cows without compromising milk yield or GDMI.This research was funded by the ICAMEX-Estado de MĂ©xico under grant number 15-2005-
