In the above mentioned article (Fernández et al. Reference FERNÁNDEZ, LÓPEZ and LACHICA2015), we regret to announce that Table 2 contained an incorrect footnote.

The correct version is supplied below.

Table 2. Daily energy (kJ/kg0·75 BW) and carbon–nitrogen (g/kg0·75 BW) balances, heat production (HP) and retained energy (RE) of female dry Manchega sheep (n = 12; 58 ± 1·2 kg BW as average; four sheep per diet) with the three offered diets based on cereal grain (CGR), fibrous by-products (FBP) and alfalfa hay (ALH) calculated by indirect calorimetry (RQ method) and carbon–nitrogen balance (CN method)

s.e.m., standard error of mean; degrees of freedom = 2; MEI, metabolizable energy intake; RQ, respiratory quotient; CO2, carbon dioxide; CH4, methane; C, carbon; N, nitrogen.

* Calculated as RE = MEI − HP.

† Calculated as RE = 51·8 × C retained − 19·4 × N retained.

‡ Calculated as HP = MEI − RE † .
