	abstract = {FeedSmart is an app designed for smartphones, tablets, and computers to help farmers make instant and accurate decisions around feed management. The accuracy of the FeedSmart app was assessed in an intensive controlled nutrition trial, over two consecutive years. The objective of the trial was to compare a maintenance (M) diet to a restricted diet, 0.6 of maintenance (R), over a 55-day period in sheep. In the first year, 48 animals were split between M and R groups. In the second year, 274 ewes were divided into light (L) and heavy (H) groups, then into M and R. The FeedSmart app was used to calculate the area required for both M and R groups. Based on previous data, restricted animals were expected to lose 7.1\% of their body weight over the 55-day period. The changes in year 1 M and R groups and year 2 HM and HR groups were not significantly different from the expected changes. The weight changes in the year 2 LM and LR groups were significant, but were within the errors associated with the calculations underlying the FeedSmart app. In these trials, the FeedSmart app provided an accurate tool for feed management.

	abstract = {The Inverdale gene (FecX) affects ovarian development, during both  foetal and adult life. There is evidence for affects on germ-cells, the  follicle and the corpus luteum. In I+ewes, follicles ovulate at a small  diameter with fewer granulosa cells and the resulting corpora lutea are  individually smaller compared to those in control (++) animals. This  appears to be due to the granulosa cells in I+ follicles being more  responsive to follicle-stimulating hormone (FSH) and acquiring receptors  for luteinising hormone (LH) earlier than in cells from ++ ewes. These  differences between I+ and ++ ewes in ovarian characteristics occur in  the absence of any obvious differences in the peripheral plasma  concentrations of FSH and LH or the ovarian secretion rates of inhibin,  oestradiol and progesterone. In II animals, ovarian follicular growth  is impaired at the primary stage of growth during foetal, neonatal and  adult life. No normal follicles beyond this stage of growth have been  observed. II animals also have castrate levels of FSH and LH and  undetectable plasma levels of ovarian steroid or inhibin. In ~35\% of II  animals, abnormal surface-visible structures have been observed with a  morphology consistent with that of a sertoli-cell or sex-chord stromal  tumour. These structures, which secrete inhibin, appear to develop from  clusters of oocyte-free follicles.   },

	abstract = {Two hundred and thirty 5-year-old Romney ewes were synchronised with progestagen intravaginal sponges and injected with dexamethasone 142 or 143 days after the median mating day of the first and second cycles of oestrus. Seventy-one \% of the lambs were born 30 to 50 h after injection. The ewes were offered 2 pasture allowances for the last 6 weeks of pregnancy (approximately 6 and 1 kg DM/ewe/d). Lambs were vigour scored (1 to 10) and probed for rectal temperature and ewe lambs were cross-fostered as soon as possible after birth in order to obtain a 2 4 factorial design incorporating birth type (single and twin) rearing types (single and twin), pre-natal nutrition of dam (high and low allowance), and pre-natal nutrition of foster dam (high and low allowance). Lambs born from high allowance ewes had higher rectal temperatures at birth than those born from low allowance ewes, and female lambs had higher rectal temperatures than male lambs. Single-born lambs scored higher on vigour than those born as multiples. Increasing vigour was associated with increasing birth weight for all lambs, but increasing temperature was associated with increasing birth weight only for male lambs. There were no effects of pre-natal nutrition on lamb growth either through the dam or foster dam. The effect of birth type on lamb live weight was significant to 9 weeks of age whereas the effect of rearing type was significant to 33 weeks. There were no significant birth type x rearing type interactions at any age.},
