	abstract = {In an experiment replicated over three years, ewes were individually fed concentrate diets containing two levels of protein (12 and 18\%) at either maintenance or 1.5 x maintenance from days 35 to 74 of pregnancy, and then at an allowance of approximately 2.0 kgDM/head/day on pasture until parturition. Half of the ewes within each treatment were shorn on day 74. Ewes were CT scanned to measure body composition at days 35, 74, 115 and 140 of pregnancy. Neither protein nor energy level fed during mid-pregnancy had any significant effects on conceptus growth, birth weight or lamb skeletal measurements. Shearing resulted in changes in ewe body composition as well as an increase of 0.36 kg (P<0.01) in lamb birth weights. Lambs from the shorn ewes were 14 mm longer in length (P<0.05) but 8 mm shorter in height (P<0.05) than those from unshorn ewes. Shorn ewes lost 1.3 kg more body fat (P<0.001) than their unshorn contemporaries over the second half of pregnancy. Unshorn ewes lost 0.74 kg of carcass lean over this period, while the shorn ewes gained 0.22 kg (P<0.001). The results show that ewes can be fed maintenance during mid-pregnancy if this allows good quality feed reserves to be built up in front of them for the third trimester. Mid-pregnancy shearing is likely to increase lamb survival in multiple born lambs through higher birth weights.},

	abstract = {This study investigated apparent reproductive failure occurring  in seasonally anoestrous progesterone-primed red deer hinds when they  were induced to ovulate with the GnRH analogue, buserelin. In March  1988 (non-breeding season), each of 11 progesterone-primed red deer  hinds(Groups B and BO) were injected i.m. with 4, 3, 2, 2 and 10 ug  buserelin (Receptal, Hoechst) at -48, -24, 0, 24, and 48 h relative to  the time injected i.m. with 500 ug oestradiol benzoate. During the  breeding season (April), ovulation was synchronised in another 4 hinds  (Group C) using CIDRs. Oestrous behaviour was less noticeable and  delayed (P>0.05) in Group B hinds and peak LH levels were lower (P>0.01)  and occurred later (P>0.01) relative to Group ), BO and C hinds. Two  weeks after CIDR withdrawal 3/5 B, 2/4 O, 3/6 BO and 4/4 C hinds had a  corpus luteum present.  During theses two weeks plasma  progesterone levels were elevated in B, BO and C hinds but were low in  the O hinds. None of the buserelin- and/or oestradiol-induced  ovulations resulted in pregnancy. These results show that ovulations  induced in these anoestrous red deer hinds by the use of a GnRH analogue  or oestradiol were not accompanied by normal hormonal and behavioural  patterns.  },

Serum   gamma-glutamyl transferase (GGT) levels of individual animals were   determined on 21 April. The ewes were divided into 3 classes for   analysis based on the GGT levels: 1.<100 IU/1;2. 100-350 IU/1; and   3.>350 IU/1. At all matings over 4 years the ewes in class 3 had a   lower fertility than class 1. These differences were only significant   at the hogget and two-tooth mating. The total number of lambs weaned   per ewe mated were class 1-5.0; class 2-4.4; and class 3-4.3 (P<0.1).   There were no lifetime effects on fleece weight.    },

	abstract = {Significant numbers of livestock in New Zealand are now grazed on the understorey of Pinus radiata. Fresh foliage of radiata pine contains aromatic monoterpenes and decaying needles resin acids. As livestock grazed under trees are know to eat both fresh and decaying pine needles, a study was made to find out if the meat quality characteristics of lambs grazed under P. radiata were affected. Groups of Romney wether lambs were grazed for 49 d under P. radiata at 100 and 200 stems/ha and on open pasture (no trees). In addition, 2 groups were stall fed for 21 d with 23 and 21\% of their intake as fresh or decaying pine needles respectively. All the lambs were slaughtered on the same day. Meat samples from each were subjected to a range of meat quality tests. Meat from the lambs grazed under the trees, or consuming fresh or decaying needles had slightly different colour and muscle pH levels, but there were no significant effects on its flavour, aroma, texture, juiciness or tenderness. It was concluded that there are no meat taints associated with lambs grazed under radiata pine.},

	abstract = {Matched groups of ewe hoggets were mated to either fertile Southdown rams or vasectomised rams for a 6-week period in 1980 and 1981. The percentage of Romney, Coopworth and Perendale hoggets born in 1979 showing oestrus were 82, 92 and 92, and for those born in 1980 47, 84 and 79 respectively. The lower incidence of oestrus in those born on 1980 can be partly explained by lower hogget pre-lambing weights related to an outbreak of facial eczema in April 1981. Of hoggets joined to fertile rams, the percentages that weaned a lamb were 47, 60 and 67 for those born in 1979, and 13, 53 and 52 for those born in 1980. The percentages of two-tooths joined that weaned a lamb (average for those born in 1979 and 1980) were 71 for those not tupped as hoggets, 74 for those tupped by vasectomised rams, 53 for those tupped by fertile rams but not lambing, and 76 for those lambing as hoggets. There was no suggestion that hogget lambing impaired two-tooth reproduction, but those lambing produced 0.15 kg less wool at the two-tooth pre-mating shearing. The April 1981 GGT level of the 1980-born ewes was inversely related to live weight in April through to September 1981, and to percentage of ewes lambing as hoggets and as two-tooths, and to two-tooth pre-mating fleece weight.},
