Resumo: | The effects of early weaning (EW) and temporary calf remova' (TCR) on beef cattle cows and their calvos wereevaluated. Also were assessed: the weight at beginning of the breeding season (WBBSc), the weight at beginning of the earlyweaning (WEWc), the weight at the end of breeding season (WEBSc), the final weight (FWc), the average daily gain (ADGc),and the pregnancy rate (PR), for the cows. It was evaluated the early weaning weight (EWWcalf), the weight at the end of thetrial (Ewcalf), and the average daily gain (ADGcalf), for the calves submitted to EW or TCR. The breeding season started at 12/01/97 and finished at 02/28/98. The EW was measured at 01/03/98, and the TCR at 12/02/97, 01/03/98, and 02/03/98. WBBSc,WEWc, WEBSc, and FWc were 427.0 and 446.9 kg, 432.9 and 343.9 kg, 464.0 and 452.4 kg, 472.5 and 435.5 kg, for the cowssubmitted to EW and TCR, respectively, with no significance (P>0.05). However, the ADGc, from 12/01/97 to 02/28/98, was0.421 and 0.059 kg/day to the EW and TCR, respectively (P< 0.01). The PR was 90%, for the EW group, and 23.8 %, for theTCR group (P<0.01). The Ewcalf was 143.1 and 172.1 kg, for the EW and TCR groups, respectively, (P<0.01). The ADGcalfwas 0.237 and 0.532 kg/day (P<0.01), respectively, for calves submitted to EW or TCR group. The cows submitted to EWshowed a higher PR and ADGc. However, the calves in the TCR group showed higher Ewcalf and AVDcalf than the EW calves. |

Para as vacas, foram avaliados: peso ao início do acasalamento (PIAv), peso ao início do desmameprecoce (PDPv), peso ao final do acasalamento (PFAv), peso final (PFv), ganho médio diário (GMDv) e taxa de repetição deprenhez (TP). Para os terneiros, foram avaliados: peso ao desmame precoce (PDPt), peso ao final do experimento (PFt) eganho médio diário (GMDt) de terneiros submetidos aos tratamentos DP e AI. A estação de acasalamento foi de 01/12/97 a 28/02/98, o DP foi realizado em 03/01/98 e o AI, em 02/12/97, 03/01/98 e 03/02/98. Os dados de PDPv, PFAv, GMDv, PDPt, PFte GMDt, foram obtidos através de análise de variância e avaliados pelo teste-F. A TP foi analisada pelo Qui-quadrado. O PIAv,PDPv, PFAv e PFN, foram de 427,0 e de 446,9 kg, 432,9 e 343,9 kg, 464,0 e 452,4 kg, e 472,5 e 435,5 kg, para as vacas do grupoDP e AI, respectivamente, sem diferença significativa (P>0,05). Entretanto, o GMDv, no período de 01/12/97 a 28/02/98, foide 0,421 e 0,059 kg/dia, para DP e AI, respectivamente (P< 0,01). A TP foi de 90%, para DP, e 23,8 %, para AI (P<0,01). OPFt foi de 143,1 kg, para DP, e 172,1 kg, para AI (P<0,01), e o GmDp-Pf foi de 0,237 e 0,532 kg/dia (P<0,01), para terneirosDP e AI, respectivamente. As vacas submetidas ao DP apresentaram maior TP e maior GMD, entre janeiro e maio, enquantoos terneiros do grupo Al apresentaram maior PFt e GMD.Departamento de Diagnóstico e Pesquisa Agropecuária.
