Low-cost mobile open-circuit hood system for measuring gas exchange in small ruminants: From manual to automatic recording

In the above mentioned article (Fernández et al. 2015), we regret to announce that Table 2 contained an incorrect footnote.

The correct version is supplied below.

Table 2. Daily energy (kJ/kg^0·75 BW) and carbon–nitrogen (g/kg^0·75 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 ^† .
