Energy metabolism of pregnant zebu and crossbred zebu dairy cattle
The purpose of this study was to determine the energy partition of pregnant F1 Holstein x Gyr with average initial body weight (BW) of 515.6 kg and Gyr cows with average initial BW of 435.1 kg at 180, 210 and 240 days of gestation, obtained using respirometry. Twelve animals in two groups (six per genetic group) received a restricted diet equivalent to

Genomic Analysis of Taurine and Indicine Ancestry in the Montana Tropical Composite Population. [PDF]
ABSTRACT The Montana Tropical cattle, a Taurine and Indicine composite, were developed in Brazil since 1994 and were based on crossing four biological types of cattle: zebu (mainly Nelore), tropical adapted taurine (mainly Senepol and Romosinuano), British taurine (mainly Angus) and continental taurine (as Charolais, Simental and Limousin).

Inbreeding depression in Zebu cattle traits. [PDF]
SummaryThe productivity of herds may be negatively affected by inbreeding depression, and it is important to know how intense is this effect on the livestock performance. We performed a comprehensive analysis involving five Zebu breeds reared in Brazil to estimate inbreeding depression in productive and reproductive traits.

Anticorps monoclonaux anti-IgGs de zébu. Réactivités comparatives
En utilisant des anticorps monoclonaux (Amclx) anti-IgGs de zébu, plusieurs sortes d'épitopes ont pu être identifiés : spécifiques du zébu, communs au zébu et au boeuf, au zébu et au mouton ou aux trois espèces.

Ingestive behavior of Guzerat and Sindhi heifers under the effects of feed restriction=Comportamento ingestivo de novilhas Guzerá e Sindi sob efeito de restrição alimentar [PDF]
This study aimed to evaluate the effect of feed restriction on the ingestive behavior of Guzerat and Sindhi heifers. A total of 36 heifers were used, 18 from each breed, randomly distributed in a completely randomized design, in a 2 x 3 factorial scheme.
