The concentration of blood sugar during starvation in the newborn calf and foal.
Abstract: Graham, Sampson and Hester (1941) observed that hypoglycaemia was a pathognomonic feature in a fatal disease of newborn pigs and subsequently made the important observation that
starvation alone could rapidly produce a similar syndrome (Sampson,
Hester and Graham, 1942). In contrast, Hanawalt and Sampson
(I947a) found that older pigs, weighing between 20 and 40 lb., were
resistant to a long period of starvation (24 and 28 days), the main
development of this resistance occurring during the first week of life
(Hanawalt and Sampson, I947b). Thus starvation from birth was
fatal in less than 30 hours, whereas if the pigs were 7 days old when
first starved, death did not follow until nearly 2 weeks later. The
survival time of pigs that are removed from the sow at birth, however, is subject to considerable variation and it has been shown that
the ambient temperature is one of the major determinants in this
respect (Morrill, 1952). Goodwin (1955) believed that hypoglycaemia was a non-specific sign in the pathology of the new-born
pig and that, like azotaemia, it represented a common end-point in
the pathogenesis of many diseases. Hence there are both clinical and
fundamental reasons for observing the effect of starvation on the newborn of other farm animals. Sampson, Taylor and Smith (1955)
found that the new-born lamb does not develop hypoglycaemia so
rapidly as the new-born pig when starved and this paper presents
similar data for the new-born calf and foal. In addition to observing
the stability of the blood-sugar concentration and the general
clinical signs during starvation in these last two species, the present
experiments have provided information on the blood-glucose level
.during the first hours of life.

This research article presents a study on the effects of starvation on the blood sugar levels of newborn farm animals, specifically calves and foals, and how these levels compare to those observed in pigs and lambs. The researchers also delve into influences such as age and environment on an animal’s survival under starvation.
Background
- Previous research revealed that newborn pigs suffering from hypoglycaemia often succumbed to a fatal syndrome associated with starvation. Older pigs showcased resistance to extended periods of starvation.
- Interestingly, survival times for newborn pigs removed from their mothers varied significantly, with ambient temperature cited as a primary factor affecting this.
- Other research suggested that hypoglycaemia was not a specific sign but more of a common end-point observed in the progression of many diseases in newborn pigs.
Purpose of the Study
- The researchers aimed to explore the effects of starvation on the blood sugar concentration of newborn calves and foals. They also intended to understand how factors such as age and surrounding environmental conditions affect the animals’ survival under starvation.
- In addition, earlier studies found that newborn lambs did not develop hypoglycaemia as quickly as pigs when starved. Hence, this research provides similar data for newborn calves and foals, enhancing our understanding of blood sugar concentrations across various young farm animals under starvation.
Methodology and Results
- The researchers observed the stability of the blood sugar concentration during starvation, along with the general clinical signs in calves and foals.
- The study also delivered information on the blood glucose level during the initial hours of life in these animals.
Significance of the Research
- Understanding the blood sugar levels during starvation and the factors influencing these levels can provide critical insights into the health and survival of newborn farm animals under such conditions.
- The research can guide appropriate feeding and healthcare strategies for farm animals, particularly newborns, thus improving their chances of survival and overall well-being.
