The present study investigated the effect of parity on plasma insulin level around parturition in Saanen goats. On d -14, -7, 0, 3, 7, 10, and 14 from parturition, plasma glucose, NEFA, free AA, cortisol, and insulin concentrations were analyzed in 10 primiparous and 10 multiparous goats. At parturition, BW of primiparous goats was about 75% of that of multiparous ones (P < 0.001) and then thei...

A study was conducted to investigate serum biochemical and micro mineral status on 18 kankrej cattle during transition period. The transition period for present study was defined as last four weeks before parturition and first four weeks after parturition and it was divided into three stages viz., stage-I (late pregnancy), stage-II (recent parturition) and stage-III (early postpartum). Serum bi...

During parturition, uterine-derived prostaglandins (PG) play an outstanding role regarding the functional elimination of the corpus luteum and the promotion of uterine contraction. The rate-limiting enzyme cyclooxygenase-2 (COX-2), highly regulated in a cell-type and localization specific manner throughout pregnancy, is involved in uterine prostanoid production. Prostaglandins exert their effec...

This study investigated the correlation between the body surface temperature (BST) and core body temperature of ewes and changes in BST during the prepartum stage in pregnant ewes. Four non-pregnant adult ewes were used in the first experiment. The BST of the upper neck, vaginal temperature (VT), and ambient temperature (AT) were measured every 10 min for seven days and analyzed for correlation...

Twelve first-calf, 2-year-old, Hereford heifers were randomly assigned in equal numbers on two levels of energy (17.6 Meal DE/day and 11.4 Mcal DE/day) beginning 100 days prepartum. Jugular blood was collected three times weekly from the heifers starting 14 days before parturition, and continuing through the postpartum period until 20 days following the first estrus. There was no significant ef...

Subclinical mastitis (SCM) is a very common disease of dairy cows. Currently, somatic cell count (SCC) used for SCM diagnoses. There are no prognostic tests to detect which cows may develop during the dry-off period. Therefore, objectives this study were identify metabolic alterations in serum pre-SCM period, at −8 and −4 weeks before calving, through targeted mass spectrometry (MS) assay. Fift...

The process of parturition involves the complex interplay of factors that change the excitability and contractile activity of the uterus. We have compared the relative gene expression profile of myometrium from rats before parturition (21 days pregnant) and during delivery, using high-density DNA microarray. Of 8,740 sequences available in the array, a total of 3,782 were detected as present. F...

Objective: The objective of this study was to evaluate nutritional status of high yielding dairy cattle around parturition. Materials and methods: Nutritional status of cows around the peri-parturient period was investigated for six months in dairy farm. Seven to eight months’ pregnant cows were selected for this study. Blood samples from 24 randomly selected cows were collected at stage-1, -2 ...

In mammals, the activation of maternal behaviour depends on internal maternal factors related with parturition. The nature of these factors may vary between species, although oestradiol, foetus expulsion and intracerebral oxytocin are the most commonly encountered. They induce a period of specific receptivity to some sensory cues provided by the neonate. These cues (tactile, olfactory, auditory...

BACKGROUND Changes in colostrum composition of Egyptian buffaloes and Holstein cows collected at calving, 6, 12, 24, 48, 72, 96, 120 h and after 14 days of parturition were studied. Total solids, total protein, whey proteins, fat, lactose and ash contents were determined. Macro- and micro-elements, IgG, IgM, IGF-1, lactoferrin and vitamins (A and E) were also estimated. RESULTS At calving, th...
