“…In natural estrus, the number of mounts received (30.40±3.14) was higher than that verified by Mattoni et al (1988) in Zebu type cows that stayed with vasectomised bulls (9.2 mounts), and similar to that reported by LamotheZavaleta et al (1991) in the presence of penis-deviated bulls (28.8 mounts). In induced estrus, the number of mounts (30.23±3.10) was smaller than that reported by Orihuela et al (1988) in Indubrazil breed cows kept with the bull (51.2 mounts) and similar to that observed in the group in which the bull was absent (34.3 mounts). Smaller number of mounts were observed by Galina et al (1982) in Brahman x Charolais cross cows (18.9 mounts) in the absence of bulls or teaser bulls.…”

The estrus behavior was evaluated during an induced and natural subsequent estrus in twelve Guzera breed cows, in the winter and summer seasons in two consecutive years. The proportion of cows that responded to estrus synchronization was 84.8%. The effect of the interaction season x year of experiment on estrous cycle length was observed. Pro-estrus was longer in the summer (57.69±4.72h) and in the natural estrus (74.23±4.41h) than in the winter (38.95±4.02h) and in the induced estrus (22.40±4.36h). Estrus length was similar in the winter (11.48±0.70h) and in the summer seasons (13.40±0.82h) as well as among cows with induced (12.47±0.75h) and natural estrus (12.41±0.76h). The number of mounts accepted during estrus and the number of mounts accepted/ hour in estrus were similar in winter (29.17±2.86 and 2.59±0.22, respectively) and summer (31.45±3.36 and 2.42±0.26, respectively) as well as between induced (30.23±3.10 and 2.54±0.24, respectively) and natural estrus (30.40±3.14 and 2.47±0.24, respectively). The length and intensity of estrus were not influenced by synchronization or season of the year. Longer period of pro-estrus in summer may favor the identification of sexually active animals in this season. Index terms:Estrus synchronization, season of the year, zebu. RESUMOA manifestação do comportamento estral foi avaliada durante um estro induzido e o estro subseqüente, em 12 vacas da raça Guzerá, no inverno e no verão em dois anos consecutivos. A proporção de vacas que respondeu à sincronização de estros foi de 84,8%. Observou-se efeito de interação entre estação e ano sobre a duração do ciclo estral. O proestro foi maior no verão (57,69±4,72h) e no estro natural (74,23±4,41h), que no inverno (38,95±4,02h) e no estro induzido (22,40±4,36h). A duração do estro foi similar no inverno (11,48±0,70h) e no verão (13,40±0,82h), assim como entre as vacas com estro induzido (12,47±0,75h) e natural (12,41±0,76h). O número de montas recebidas durante o estro e o número de montas recebidas/hora em estro foram similares no inverno (29,17±2,86 e 2,59±0,22, respectivamente) e no verão (31,45±3,36 e 2,42±0,26, respectivamente), assim como entre o estro induzido (30,23±3,10 e 2,54±0,24, respectivamente) e o natural (30,40±3,14 e 2,47±0,24, respectivamente). A duração e a intensidade do estro não foram influenciadas pela sincronização ou pela estação do ano. O maior período de proestro no verão pode favorecer a identificação dos animais sexualmente ativos.Termos para indexação: Sincronização de estros, estação do ano, zebu.

“…For example, not all heifers in a herd mount cows in estrus [ 88 ]. Orihuela et al [ 89 ] found that 60% of the mounts among females were performed by a heavier and larger cow than the one being mounted. Similarly, when evaluating a herd composed of Charolais and Brahman cows, it was observed that most of the mounts were carried out by Charolais cows on Brahman cows, which were comparatively larger and heavier than the latter, while Brahman cows rarely rode Charolais cows [ 90 ].…”

“…Environmental temperature is also a factor, and in general, B. indicus cattle show sexual behavior more frequently during the hot summer months [ 101 ], compared to European cattle that manifest more in cold climates [ 102 ]. However, although Zebu cattle are better adapted to the heat, most of the sexual activity seems to take place during the cooler hours of the night [ 89 , 95 ].…”

The Effect of Maternal Behavior around Calving on Reproduction and Wellbeing of Zebu Type Cows and Calves

The behaviors associated with domestic cattle such as maternal care are quite similar to those behaviors observed in wild ungulates. These behaviors allow the cow to bond with her calf, protect and provide it with nourishment and ultimately reduce the bond at weaning. Although maternal behavior is an important factor influencing the survival and early development of the newborn calf, Zebu type cows around calving have not been studied extensively. Herein, we consider the four main aspects of maternal behavior in cattle and particularly Bos indicus cows and calves. Firstly, we provide a brief description of the behavior of cows around parturition and the behavior of the first stages of the calves’ lives. In the second part, the protective behavior of the mother is analyzed. Subsequently, examples of animal welfare implications followed by an analysis of some factors that affect calf survival, including mother experience and weather conditions, are discussed, and in the last part, reproduction along with some peculiarities of reproductive behavior, and the wellbeing of mother and calves are examined. We concluded that knowledge of maternal behavior of Zebu type cows around calving and interactions with calves might contribute to an enhanced reproductive efficiency of the mother and the welfare of the calf.

Social organization and breed effects following PGF2alpha were studied in mature Angus, Brahman and Senepol cows allocated into two groups (each A = 5, B = 5 and S = 5). Variables including interval to oestrus onset (IEO), oestrous duration (DE), total mounts received (TMR), and oestrous intensity (IE) were derived via HeatWatch. Breed-type influenced IEO (B = 42.6 +/- 6.7 h; S = 54.6 +/- 6.0 h; and A = 27.8 +/- 5.8 h; p < 0.003). Within breeds, dominant B (69.4 +/- 13.3 h) and S (65.5 +/- 7.4 h) cows were slower (p < 0.05) to be detected in oestrus than subordinate (38.1 +/- 4.4 h) and intermediate (40.6 +/- 6.0 h). However, within A, dominant cows (16.4 +/- 12.5 h) were detected in oestrus earlier (p < 0.05) than intermediate (44.3 +/- 9.2 h) and subordinates (32.7 +/- 5.1 h). Angus (21.5 +/- 2.4 h) and B (22.1 +/- 3.0 h) cows had longer (p < 0.01) DE than S (9.1 +/- 2.8 h). Dominants (20.4 +/- 3.0) and intermediates (20.2 +/- 2.3 h) cows had longer DE (p < 0.04) than subordinates (12.1 +/- 2.1 h) although the interaction breed x social order showed that dominant S had shorter DE than dominant A and B (10.1 +/- 3.3; 34.8 +/- 6.0 h; and 20.0 +/- 6.4 h, respectively; p < 0.001). Angus cows had less TMR than B (p < 0.02) and tended to be less than S cows (p < 0.06). Overall, greatest (p < 0.008) IE occurred in the first 9 h after onset of oestrus with no breed effect (p > 0.05). Dominant cows tended (p < 0.10) to have less TMR (3.2 +/- 0.7 mounts) than subordinate (4.1 +/- 0.4 mounts) and intermediate (4.7 +/- 0.6 mounts) throughout, especially 3-6 h after oestrus onset (p < 0.07). Breed and social order both influence PGF2alpha-induced oestrus behaviour.
