There have been few studies on the use of diets and strategies to reduce length postpartum anoestrus in dairy goats, especially tropical semi-arid regions. This review discusses factors influencing return ovarian activity goats. During period, goats are puerperal their reproductive tract is being prepared for a new conception. Anoestrus necessary tissue renewal uterus (uterine involution...

There is no doubt that in breast-feeding women, suckling with its associated hyperprolactinaemia prevents the resumption of ovarian activity for prolonged periods (see McNeilly, 1979). The extent of this suppression varies greatly among species but in all for which there are adequate data it appears to depend critically upon the intensity of the suckling stimulus (Lamming, 1978). Our recent dat...

Two experiments were performed to test the hypothesis that suckling behavior of calves with similar growth potential varies depending on cows' level of estimated milk production and stage of lactation. Eleven mature cows, which varied in estimated 205-d milk production (996 to 2354 kg/205 d), nursing heifer calves of similar growth potential were used in Exp. 1. Suckling behavior of calves was ...

background: vanadium is an important environmental and industrial pollutant. it has a status of reproductive toxicant and is reported to cross placental barrier. objective: the current study was performed to assess the therapeutic efficacy of tiron and its combination with selenium against vanadium induced toxicity in lactating and suckling rats. materials and methods: rats were exposed to vana...

Physicochemical and organoleptic characteristics of meat (longissimus muscle) from Criollo Cordobes (CC) and Anglonubian (AN) suckling kids were analysed to determine the effects of genotype and slaughter weight. Forty suckling entire male kids, 20 CC and 20 AN were assigned to two age/slaughter weight groups (I: 60+2days old and ⩽11kg, and II: 90+2days old and >11kg). Colour, shear force and c...

For detection of cholera enterotoxin activity, suckling hamster, mouse, and rat models were compared. It was found that not only suckling mice but also suckling rats and hamsters were sensitive to cholera enterotoxin. Among these models, suckling hamsters were the most sensitive and gave positive results with about 1/100 the cholera toxin seen in suckling mice and rats.

In Préalpes de Sud ewes after an autumn lambing, the mean post-partum interval to first LH surge was 10 +/- 1 days and 17 +/- 1 days for non-suckling and suckling ewes, respectively. Post-partum interval to first luteal phase, estimated from plasma progesterone concentrations, was similar in non-suckling and suckling ewes (27 +/- 1 days and 28 +/- 5 days, respectively). Interval to first oestru...

BACKGROUND There are not many studies exploring parity differences in early lactation performance and the results obtained are fairly often contradictory. The present study investigated the effect of different maternity home practices in St. Petersburg, Russia, as well as of physiological breast engorgement and maternal mood, on milk production in primi- and multiparous women on day four. The a...

We aimed (i) to determine differences in bacterial flora of teat duct and mammary gland of ewes before and after suckling, (ii) to evaluate factors potentially affecting those. We collected samples of teat duct material and mammary secretion from 11 ewes immediately before and after sucking by lambs, as well as 120 min later. We processed samples bacteriologically and compared changes in infect...

The mother-offspring social unit is a universal feature in the social life of all mammals and nursing is the most direct and vital component of maternal investment in young. Living in diverse environments, various ungulate species have different strategies for rearing offspring, from bearing a single, relatively large newborn and supplying only limited amounts of milk, to bearing several relati...
