Development of a novel 21-day reinsemination program, ReBreed21, in Bos indicus heifers. Repositório Alice
ANDRADE, J. P. N.; GOMEZ-LÉON, V. E.; ANDRADE, F. S.; CARVALHO, B. P.; LACOUTH, K. L.; GARCIA, F. Z.; JACOB, J. C. F.; SALES, J. N. S.; WILTBANK, M. C.; MELLO, M. R. B..
The aim was to develop a program for resynchronization of ovulation (ReBreed21) that allowed reinsemination of non-pregnant Bos indicus heifers every 21 d using timed AI (TAI) without the need for detection of estrus. The Rebreed21 program begins 12 d after previous TAI (Day 0) by inserting an intravaginal P4 implant (Day 12) that is removed 7 d later (Day 19) combined with treatment with 300 IU of eCG. On Day 21, early pregnancy diagnosis (Doppler PD) is performed based on CL vascularity. Nonpregnant (NP) heifers immediately received AI combined with 100 mg of GnRH. The program is replicated 12 d after second TAI to produce a breeding season (BS) of 42 d with 3 potential TAIs. Two ex periments were conducted as a proof of concept for this rapid rebreeding...

Feed intake and prediction assessments using the NRC, CNCPS and BR-CORTE systems in Nellore and Red Norte steers finished in feedlot R. Bras. Zootec.

The objective of this research was to evaluate the dry matter intake (DMI) and nutrient consumption in Nellore and Red Norte steer finished in a feedlot and compare the actual and predicted values by NRC (2000), CNCPS 5.0 and BR-CORTE systems. Forty-one animals, 19 Nellore and 22 Red Norte steers, with initial live weight of 361 ± 31 kg and 367 ± 30 kg, respectively, were used. The experiment lasted 84 days, with 28 days for adaptation and 56 experimental days. The animals were weighed at the beginning and at end of each 28-day period after 16 hours fasting. The dry matter intake was estimated by LIPE, chrome oxide and indigestible dry matter (DMi) markers. There were no differences between Nellore and Red Norte DMI when expressed in kg/day (10.66 vs....

Genetic parameters of Girolando crossbred cows in dairy herds in the state of Acre, Brazil. Repositório Alice
BRAGA, A. P.; CARNEIRO JUNIOR, J. M.; PINHEIRO, A. K.; SILVA, M. S..
This study aimed at estimating genetic parameters for milk production and conformation characteristics in Girolando crossbred dairy cows reared in the High and Low Acre region using the restricted maximum likelihood methodology, under an animal model. We estimated the variance components and genetic parameters using the REML/BLUP procedure (Restricted Maximum Likelihood Methodology/Best Linear Unbiased Prediction). The estimated average for milk production for 305 days of lactation (P305) was of 1523.25 ± 481.11 kg, with a heritability of 0.38 for this characteristic. The conformation characteristics showed no significant correlation with milk production. The phenotypical correlations between the linear characteristics of type were, in general, positive...

Ingestive behavior of Girolando heifers in integrated crop, livestock (ICL), and forestry (ICLF) systems. Repositório Alice
SOUZA, E. C.; SALMAN, A. K. D.; CRUZ, P. G. da; CARVALHO, G. A.; SILVA, F. R. F..
Aiming to compare integrated crop, livestock (ICL) and forest (ICLF) systems in relation to ingestive behavior of dairy heifers, a 2 × 2 crossover trial was conducted with two periods and two systems. Eight Girolando (3/4holstein × 1/4 Gyr) heifers were evaluated in pasture of Xaraés palisade grass (Urochloa brizantha 'Xaraes' syn Brachiaria brizantha) managed with intermittent stocking. The ICLF systemhad eucalyptus trees planted in tiers with 65% crown cover. Ingestive behavior parameters were obtained using acoustic data collected with mP3 recorders for 48hours. Statistical analysis was performed using the mixed procedure of SAS, and means were compared using the Tukey-Kramer test at 5% significance. The dry mater intake (DMI), number of daily grazing...
