SALGADO O, Roger; VERGARA G, Oscar  and  SIMANCA S, Juan. RELATIONSHIPS BETWEEN WEIGHT, BODY CONDITION AND MILK PRODUCTION IN COWS UNDER DOUBLE PURPOSE SYSTEM. Rev.MVZ Cordoba [online]. 2008, vol.13, n.2, pp.1360-1364. ISSN 0122-0268.

Objective. Evaluate the relationship between body weight, body condition and milk production in response to supplementation with whole cotton. Materials and methods. Two experimental treatments were applied to 13 cows using a randomized design: G1 (n=7), cows supplemented with 2 kg of cotton seed, and G2 (n=6), no supplemental seed. Results were analyzed using Spearman correlations. Results. There was a positive correlation between body weight and body condition (p<0,05) in the supplemented and non supplemented cows. Although there was no correlation between the variation in body weight and milk production (p>0,05) in the supplemented cows, there was positive correlation (p<0,05) for the non-supplemented cows. The body condition and milk production showed a positive correlation among (p<0,05) in the non-supplemented cows, but not in the supplemented cows (p>0,05). Conclusions. The supplementation with cotton seed had important positive relationship among body weight, body condition, and milk production in cows of first birth managed under pasturing conditions.
