Serum follicle-stimulating hormone (FSH), luteinizing hormone (LH), and prolactin (PRL) levels were examined during consecutive reproductive states in Mongolian gerbils. The results indicate that FSH, LH, and PRL levels peak at proestrus, estrus, and diestrus, respectively. During early gestation in primiparous gerbils, gonadotropin levels were the lowest on day 6. This was followed by an incre...

AIM This study was conducted to find out the relationship of prepartum udder and teat measurements with subsequent milk production traits in primiparous Nili-Ravi buffaloes. MATERIALS AND METHODS A total of 12 Nili-Ravi buffalo heifers were selected from Buffalo Farm, Central Institute for Research on Buffaloes, Regional Station- Bir Dosanjh, Nabha, Patiala, Punjab. The udder length (UL), udd...

Central prolactin (PRL) modulates neuronal activity, which is physiologically relevant and behaviorally meaningful. The stimulatory or inhibitory behavioral effects of exogenous PRL are strongly associated with dose and time of treatment. Central PRL injections produce a dual modulation of striatal dopaminergic responses in males. The activity of the striatal monoaminergic system can be modulat...

This study was conducted to evaluate the influence of category (heifers, primiparous or multiparous cows) on pregnancy rates in a large scale resynchronization ovulation program. Nelore heifers (n = 903), primiparous lactating cows (n = 338) and multiparous lactating cows (n = 1,223) were synchronized using a conventional protocol of estradiol/P4-based fixed-time artificial insemination (FTAI)....

Early weaning is used to advance postpartum ovulation in beef cows, but triggers a stress response, affecting cows' and calves' welfare. Our aim was to compare the response to early weaning in multiparous and primiparous cows. Seventy-one days after birth, calves from 14 primiparous and 11 multiparous cows were weaned. Since birth, cow's body weight (BW), body condition (BC), milk yield and cal...

The aim of the present study was to determine follicle development and resumption of ovarian activity in Bulgarian Murrah buffaloes by transrectal ultrasonographic monitoring of the ovaries during the first 50 days after after calving throughout the breeding season. The investigation included 18 clinically healthy Bulgarian Murrah buffaloes divided into two groups: Group I (n=8, primiparous buf...

The objective of the current study was to evaluate the dynamics of infection and the immunological response to varying numbers of Escherichia coli injected into the mammary glands of primiparous cows during the periparturient period. Primiparous cows have been shown to be more resistant to intramammary E. coli challenge, and an increase of the inoculum dose by 2 log10 units induced a more rapid...

Background Exclusive breastfeeding (EBF) is recommended for 6 months of age, with continued breastfeeding for 2 years of age or beyond. There is paucity of information on the disparity in Knowledge, Attitudes and Practices (KAP) on EBF between primiparous and multiparous mothers. This study compared the KAP on EBF between primiparous and multiparous mothers attending Wajir County Hospital, Waji...

Brangus cows (n = 29) were used in three experiments to evaluate the effects of parity (multiparous vs. primiparous) and potential genetic merit for milk production (high vs. low) on forage intake during late gestation, early lactation, and late lactation. Cows were selected for milk production based on their sire's EPD for milk production (MEPD). Cows had ad libitum access to (130% of previous...

Background and Aim: Post-Traumatic Stress Disorder is one of the anxiety disorders which occur in postpartum period. The prevalence of PTSD – induced by preeclampsia has been already reported as 28%, however no study was found to compare PTSD in primiparous and multiparous women. This study was therefore conducted to compare PTSD in primiparous and multiparous women. Methods: This comparative d...
