	abstract = {The pattern of GH secretion was studied in Coopworth sheep which  have been selected for low (Lean) or high (Fat) ultrasonic backfat depth over  15 years. At each of two developmental stages (February and May) Lean and  Fat ram lambs were fed ad libitum or fasted for 48 hours (n=6 per treatment).   Animals were blood sampled via an indwelling jugular cannula every 10  minutes for six hours, then slaughtered and the pituitary glands removed and  weighted.   Mean GH was greater for Lean than Fat animals (2.82 versus 1.42 ng/ml,  p<0.001), in February than in May (2.47 versus 1.62 ng/ml, p<0.001) and for  fasted than fed animals (2.48 versus 1.62 ng/ml, p<0.001). Analysis of GH  secretory patterns showed that peak frequency for Lean animals was more  than twice that for Fat animals (2.64 versus 1.17 peaks/6 hours, p<0.001).   There was no difference in the peak amplitude. In line with their higher GH  concentrations, Lean animals had significantly heavier pituitaries than Fat  animals (0.74 versus 0.52 g, p<0.001).   Selection for leanness in Coopworth sheep has altered the GH secretory  pattern of the animals. The pituitary weight may explain some of these  changes in GH secretion.  },

	abstract = {Twenty four Coopworth ewes, selected on the basis of an   increased ovarian response to lupin grain supplementation, were   ovariectomised and fitted with a Foley catheter in the abomasum. They   were individually penned and offered a low protein pelleted diet at   maintenance levels. Following a five week stabilisation period 12 ewes   were infused abomasally with 100g/d whey protein concentrate in 1 litre   of water for 8 days. Twelve ewes received 1 litre of water only. Blood   samples were collected four times daily for FSH analysis, from 2 days   before until 2 days after infusion.     Protein infusion did not influence FSH levels. Mean values were 8.5   ngFSH/ml plasma for both treatments and means for individual ewes   ranged from 4.5 to 11.5 ng/ml. These results indicate that the reported   increase in FSH with increased protein intake is not due to a direct   effect on the pituitary gland.    },
