Resumen :
This study evaluated the relationship between prenatal characteristics and body condition
and endocrine profile. A total of 25 non-lactating multiparous females were used. Body condition,
measured as body weight and perirenal fat thickness, non-esterified fatty acids (NEFA), leptin,
progesterone and 17β-estradiol were recorded at mating and 12 d of gestation. Ovulation rate,
number of foetuses, ovary and foetal weight, length and weight of uterine horn, available space
per foetus and maternal and foetal placental morphometry were recorded at 12 d of gestation.
Ovulation rate showed a positive linear relationship with number of foetuses, ovary weight and
NEFA. A negative linear relationship between ovulation rate and perirenal fat thickness and leptin
was obtained. Ovulation rate was maximum when body weight and 17β-estradiol were 4.4 kg and
22.7 pg/mL, respectively. Foetal weight showed a positive relationship with perirenal fat thickness
and a negative relationship with leptin. An increase in progesterone and NEFA concentration was
related to a positive linear increase in number of foetuses and in uterine horn weight. Space available
per foetus was affected both by the number of vessels that reach the implantation site and by position
of the foetus in the uterine horn. In conclusion, body condition during mating and early gestation
should be maintained within an optimal range to ensure the best prenatal characteristics. While 17βestradiol, NEFA and leptin affected the ovulation rate, progesterone and NEFA affected foetal
development. The number of vessels that reach the implantation site determines early foetal survival
