“…Restricted suckling is the method where there is a little more research on zebu cattle, perhaps because of the advantages that it offers as an effective procedure to shorten the calving interval, without shortening the duration of lactation. In an early study, Bastidas et al (1984) used Brahman cows and first-calf heifers undergoing a twice-daily suckling (45 minutes of suckling each time) from 30 days post-partum until weaning at seven months, and found that the mean pregnancy rate was 63.06 ± 0.06% and was influenced by nursing and number of parturitions. The pregnancy rate was 33% higher in twice-daily suckled cows.…”

Information on approaches to weaning zebu (Bos indicus) and water buffalo (Bubalus bubalis) calves is scarce in proportion to studies of breeds of B. taurus cattle, whether dairy or beef. Little research has been done to test or validate methods evolved in cattle-ranching to these other species. Hence, expanding our understanding of appropriate, speciesspecific methods of weaning could support the development of approaches or strategies that have the potential to improve animal welfare and productive performance in temperate or tropical climes. This review focuses on traditional and current weaning strategies in an attempt to improve productivity and animal welfare for water buffaloes and zebus. For the case of the water buffalo, it examines common, routine weaning techniques and procedures as well as novel approaches, while for the zebu it discusses abrupt versus gradual and early versus late weaning as strategies and routines usually employed during this process. Finally, it analyses how new weaning techniques may reduce stress while enhancing productivity at the same time. These approaches include fence-line weaning, nose-flaps (plastic devices that prevent the calf from grabbing a teat to suckle), restricted suckling and a section on practical tips to decrease the stress induced by weaning in zebus. A better understanding of certain weaning techniques could, therefore, benefit calf welfare while simultaneously increasing cows' reproductive performance. Unfortunately, data on such approaches is scant, so despite published findings, several key issues remain unsolved living room for additional studies.

“…In the case of sheep (Dingwall et al 1982) and cattle (Bastidas et al 1984b), such manipulations had no significant effect on the growth of the offspring or the yield of milk and from this one must conclude that the quantities of milk consumed by the offspring were similar, the essential difference being that this milk was obtained in one or two controlled bouts per d rather than ad lib.…”

Nutrition and body condition are known to influence reproductive performance in a wide range of mammals, including marsupials, a large number of eutherians, both wild and domesticated, and man. Nutrition is known to influence reproduction on at least four levels. First, growth and the onset of puberty are clearly under nutritional control, and for a number of species, critical body-weights for ovulation or the onset of spermatogenesis have been described. Second, postpubertal ovulation rate is known to be profoundly influenced by both proximal nutrient intake and body condition in a number of species. Third, early embryonic wastage is frequently associated with plane of nutrition although even in some of the best studied mammals such as the sheep, the evidence remains equivocal (see Robinson, 1983). Finally, the return to Oestrus post-partum is known to be regulated in many species by the sucking activity of the young. In many species with long periods of maternal dependence, plane of nutrition during lactation has a significant effect in delaying the onset of normal ovarian activity.Currently, the level of understanding of how these four categories regulate fertility is very poor. A number of studies have shown that plane of nutrition can influence the pattern of pituitary luteinizing hormone (LH) release (Fitzgerald et al. 1982; Foster et al. 1 9 8 5~; Piacsek, 1985;Steiner, 1987) and evidence is accumulating that undernutrition may directly modulate the operation of the gonadotrophin-releasing hormone (GnRH) pulse generator (Foster et al.
