TL;DR:
Sows actively immunized against GRF weighed less and had more backfat at d 110 of gestation than HSAi sows; in vitro glucose oxidation and lipogenic rate of adipose tissue were greater (P < .05 for treatment x day interaction) in GRFi than in HSAo sows at d110 of gestation; across treatment, mammary gland oxidation of glucose and glucose clearance rates increased and adipose tissues utilization of glucose decreased.

EFFECT OF FEED RESTRICTION ON SERUM SOMATOTROPIN, INSULIN-LIKE GROWTH FACTOR-I-(IGF-I) AND IGF BINDING-PROTEINS IN CYCLIC HEIFERS ACTIVELY IMMUNIZED AGAINST GROWTH-HORMONE RELEASING-FACTOR
DOMESTIC ANIMAL ENDOCRINOLOGY, 10(4), 315–324.
MeSH headings : Animals; Carrier Proteins / blood; Cattle / metabolism; Electrophoresis, Polyacrylamide Gel; Estrus / metabolism; Fatty Acids, Nonesterified / blood; Female; Food Deprivation / physiology; Growth Hormone / blood; Growth Hormone-Releasing Hormone / immunology; Growth Hormone-Releasing Hormone / physiology; Insulin / blood; Insulin-Like Growth Factor Binding Protein 2; Insulin-Like Growth Factor I / analysis; Random Allocation; Somatomedins / analysis; Vaccination
TL;DR:
The increase in serum ST levels observed during feed restriction was blocked by active immunization against GRF, however, feed restriction resulted in decreased serum IGF-I in GRFi heifers in spite of initial low levels of IGF-i (due to GRFi).

Active immunization of pigs against growth hormone-releasing factor: Effect on concentrations of growth hormone and insulin-like growth factor 1
Journal of Animal Science, 68(2), 427.
MeSH headings : Animals; Antibody Formation; Female; Growth Hormone / blood; Growth Hormone-Releasing Hormone / immunology; Immunity, Active; Immunization / veterinary; Immunization, Secondary; Insulin-Like Growth Factor I / analysis; Random Allocation; Somatomedins / analysis; Swine / immunology; Swine / metabolism
TL;DR:
Cyclic gilts were used to determine the effect of active immunization against growth hormone-releasing factor GRF(1-29)-NH2 on concentrations of growth hormone (GH) and insulin-like growth factor 1 (IGF-1) and the concentrations were lower in GRF-HSA than in HSA gilts (P less than .05).

In the first experiment, crossbred multiparous sows nursing 7.9 +/- .4 pigs per litter at 25.2 +/- .3 d of lactation were subjected to one of three treatments during the middle 8-h segment of a 24-h experimental period to evaluate effects of morphine and suckling on secretion of LH and prolactin and occurrence of estrus after weaning.

TL;DR:
The results indicate that the period of post-weaning anoestrus in summer is prolonged because of altered activity of the hypothalamic-pituitary axis, possibly because of changes in sensitivity to the feedback of oestradiol.

PULSATILE ADMINISTRATION OF GONADOTROPIN-RELEASING HORMONE TO ANESTROUS SOWS - ENDOCRINE CHANGES ASSOCIATED WITH GNRH-INDUCED AND SPONTANEOUS ESTRUS
