birth weight,

the measured heaviness of a baby when born, usually about 3500 g (7.5 pounds). In the United States, 97% of newborns weigh between 2500 g (5.5 pounds) and 4500 g (10 pounds). Babies weighing less than 2500 g at term are considered small for gestational age. Babies weighing more than 4500 g are considered large for gestational age and are often infants of mothers with diabetes.

birth weight,

n the measured heaviness of a baby when born.

---

birth

a coming into being; the act or process of being born. See also parturition.

---

birth canal

the canal through which the fetus passes in birth; comprising the uterus, cervix, vagina and vulva.

birth cohort

see cohort.

birth control

a term rarely used in dealing with animals. Instead see population control, contraception.

birth defects

see congenital defects.

birth difficulties

dystocia.

birth injury

occurs to the fetus during birth. Includes rib fracture and meningeal hemorrhage.

birth interval

the interval between succeeding parturitions. See also calving interval.

multiple birth

the birth of two or more offspring produced in the same gestation period.

birth order

the chronological order of births in a multiple birth. May have significance in causing stillbirths if the intervals between births are prolonged because of inertia.

premature birth

expulsion of the fetus from the uterus before termination of the normal gestation period, but after independent existence has become a possibility. In humans prematurity is defined as a pregnancy of less than 37 weeks in a pregnancy normally lasting 40 weeks.

birth process

comprises maturation of the fetus, relaxation of the bony pelvis and associated ligaments, softening and relaxation of the cervix, vagina, vulva and perineum, correct disposition of the fetus, contractions of the uterine myometrium and finally the only component under voluntary control, contraction of the abdominal muscles.

birth rate

the number of births during one year for the total population (crude birth rate), for the female population (refined birth rate), or for the female population of reproductive age (true birth rate). Not a term much used with reference to animals. See calving, lambing rate.

birth size

stature, including height at withers, crown to tail head length at birth.

birth weight

the weight at birth. A significant determinant of survival in any species and of the occurrence of dystocia. See also prolonged gestation.

weight

heaviness; the degree to which a body is drawn toward the earth by gravity. See also Tables 4.1 and 4.2.

apothecaries' weight

an outmoded system of weight used in compounding prescriptions based on the grain (equivalent 64.8 mg). Its units are the scruple (20 grains), dram (3 scruples), ounce (8 drams) and pound (12 ounces). See also Tables 4.2 and 4.3.

atomic weight

the weight of an atom of a chemical element, compared with the weight of an atom of carbon-12, which is taken as 12.00000.

avoirdupois weight

the system of weight still used for ordinary commodities in some English-speaking countries. Its units are the dram (27.344 grains), ounce (16 drams) and pound (16 ounces).

birth weight

weight of the newborn at the time of birth.

body weight

the animal's weight. In herbivores this is often debatable because of the variation in 'gut-fill' depending on the availability of palatable food. In the absence of scales the weights of large animals are often estimated on the basis of their age and their girth just behind the elbow. Called also liveweight. See also body condition score.

body weight-to-surface area

determination of many drug dosages is physiologically more accurate when based on body surface area rather than body weight; used particularly in cancer chemotherapy. For conversion table for use in dogs see Table 21.

equivalent weight

the weight in grams of a substance that is equivalent in a chemical reaction to 1.008 g of hydrogen. See also chemical equivalent.

weight gain

increase in body weight for specific periods; the principal measure of productivity in meat animals.

weight loss

the loss of body weight from that previously measured. This estimate must take into account the difference in 'gut-fill' and the effects of developing pregnancy and recent parturition.

metric weight

see Tables 4.1 and 4.2.

molecular weight

the weight of a molecule of a chemical compound as compared with the weight of an atom of carbon-12; it is equal to the sum of the weights of its constituent atoms. Abbreviated mol. wt. See also Table 6.

shifting weight limb to limb

sign indicative of lameness especially in horses; while standing the horse is continually shifting its weight from one limb to the opposite one of the pair.

birth weight

The weight of a newborn child which, in the US, averages 3.2 kg at 37-wk/term. See Low-birth weight, Very low-birth weight.

Patient discussion about birth weight.

Q. How to loss weight like a diet with tea,pills or other kind of healthy thing.

A. drink 8 oz of warm water with 1 tablespoon of lemon... first thing in the morning

Q. what is the normal weight of a baby? what does it say if one weights less or more than the normal ?

A. Here is a site I use very often, and this is the page concerning infants' growth and development. Because it's a statistical measure changing from different ages and races, you might find an answer there. It's all videos of pediatricians lectures:

Q. what is the right weight for a baby who just has been norn to weight ?

A. The average weight for a newborn is 2.5 - 4 kilos. A baby that weighs less than 2.5 kilos is considered 'small for gestational age' and a baby that is born over 4 kilos is considererd 'large for gestational age'.
