Figures & data

Table 1. Effect of the bolus (Inoxeramic, 51 g) on growth parameters.

ADGWS (g)
Majorera	122.95^a	104.37^b	5.98
Palmera	99.45	100.99	8.25
Tinerfeña	112.86	104.99	5.08

ADGBS (g)
Total	126.38	122.12	2.51
CY%
Total	48.83	48.17	1.09
Note: Superscript ‘a’ and ‘b’ mean significant differences between groups (P < 0.05).
SEM – standard error of means; CG – control group; BG – bolus group; ADGWS – average daily gain between weaning and slaughtering; ADGBS – average daily gain between birth and slaughtering; CY – carcass yield.
