Marsupials have a functional placenta for a shorter period of time compared to that of eutherian species, and their altricial young reach the teats without any help from the mother. We have monitored the short intrauterine development of one marsupial, the tammar wallaby, with high-resolution ultrasound from reactivation of the 100-cell diapausing blastocyst to birth. The expanding blastocyst c...

Samples of weaning foods and other sources of contamination, such as water, mother's nails, utensils and swab samples of feeding bottle nipple, mother's teats and child's hands were collected from a total of 100 houses of Low Income Group (LIG) in Chandigarh. A high incidence of E. coli isolation (72.3%) was noticed amongst the collected samples. Seventy nine per cent of storage containers of w...

Despite the many empirical successes of QCD, there are a number of intriguing experimental anomalies that have been observed in heavy flavor hadroproduction, in measurements of azimuthal correlations in deep inelastic processes, and in measurements of spin correlations in hadronic reactions. Such phenomena point to color coherence and multiparton correlations in the hadron wavefunctions and phy...

An outbreak of buffalopox in domestic buffaloes, with high morbidity and significant production loss, was recorded in the Aurangabad district of Maharashtra State in India in November 2003. The disease was also associated with several cases of human infection, particularly in milkers working with the affected herds. Pox lesions were observed on the udder and teats of the majority of the affecte...

Social status in randomly constituted groups of male CFLP mice was predictable from early suckling behaviour and rate of weight gain in natal litters. High-ranking males were those that had suckled on more anterior teats and gained weight more quickly. Rank was not predicted by any measures of sibling interaction or hormone (testosterone, corticosterone) concentration. Aggressiveness in eventua...

The genetic improvement in litter size in pigs has been substantial during the last 10-15 years. The number of teats on the sow must increase as well to meet the needs of the piglets, because each piglet needs access to its own teat. We applied a genetic heterogeneity model on teat number in sows, and estimated medium-high heritability for teat number (0.5), but low heritability for residual va...

We present a model that simulates the evolution of teat massaging (begging) by suckling piglets (Sus scrofa) and milk distribution among teats (provisioning) by their mothers. Contrary to previous begging models, this one incorporates an ontogenetic dimension in that the inherited begging and provisioning rules are repeatedly allowed to interact, and their consequences for milk intake, growth a...

The article highlights the relevance of udder hygiene, sources milk contamination with microflora, treatment requirements, sanitary condition control teats skin cow udders, as well a list products authorized in Ukraine.
 Proper preparation for milking, namely: special detergents and disinfectants, compliance correct milking procedure significantly reduce risk cows mastitis increase yield. ...
