	abstract = {This experiment investigated the effects of differing nutritional levels on yearling pregnancy loss, and the live weight and survival of their offspring to weaning. Yearlings were offered either Medium or Ad-libitum levels of herbage from four days prior to breeding (P-4) until P145. Nutrition during pregnancy had no effect on pregnancy loss or lamb live weight from Day 0 of lactation (L0) until L55. Lambing percent was higher (P <0.05) in the Ad-libitum treatment compared to the Medium treatment. Single born lambs were heavier (P <0.05) than twin born lambs at L0 and at L55. Ad-libitum treatment yearlings were heavier (P <0.05) than Medium treatment yearlings at L55. Modelling of the live weight trends indicated that from P-4 until P145 the pregnant yearlings in the Medium and Ad-libitum treatment groups consumed 8.1 and 14.4 kg DM/kg of lamb live weight at L55. This indicates that the greater yearling live weight gain in the Ad-libitum group utilised more herbage during the yearling{\textquoteright}s first winter without any increase in the performance of their offspring. The extra 9 kg gained by the yearlings fed Ad-libitum may have positive effects on future performance as they will gain a suitable live weight for breeding as a two year old earlier.},

Sire progeny groups accounted for 6.5\% of the variation among samples in loose wool felting (P<0.10) and 12\% in yarn shrinkage (P<0.05). Fibre traits most highly correlated with feltball diameter were loose wool bulk (r = 0.65 for Romneys and 0.73 for {\textonequarter}M), crimp frequency (r= 0.53 and 0.41 respectively) and lustre (-0.30 and -0.40 respectively). Loose wool bulk (r= -0.25) and greasy fleece weight (r=-0.40) were most correlated to yarn shrinkage. These results suggest that low-shrinkage wools could be produced by selecting rams on shrinkage of yarn. Loose wool feltability might also be changed by direct or indirect selection. },

	abstract = {The effects of a supplemental oral drench of rumen-protected methionine (Mepron{\textregistered}) on wool growth and weight gain was studied in 2-3y non-mated Romney ewes during nine months from March to December. Three groups of 20 sheep received either 0, 4 or initially 8 (later 2) g of methionine daily. The ewes were rotationally grazed as a single mob on ryegrass-white clover pasture with winter restrictions. Pasture availability was monitored weekly. Mid-side wool samples were taken at two-monthly intervals and analysed for yield. Full fleece samples were collected during end of trial shearing and analysed for yield, fibre diameter, colour, staple length, crimp and style. Sheep were weighed weekly and herbage intakes estimated in August and November. Blood samples for plasma cysteine determinations were collected in June, August and November. There were no significant differences between the control and 4g/d groups in clean wool growth from mid-side patches (mean 1260 mg/cm{\texttwosuperior}/d), greasy fleece weight (4.12kg) or final live-weights (63.1kg). Average estimates of pasture intake were non-significantly lower in supplemented sheep in August but approached significance in November (P<0.11). There were no treatment effects on wool growth rate or wool characteristics even though Mepron increased (P<0.05) plasma cysteine concentrations (umolar) (control 40.5 vs 4g/d 45.3) in June and in August (25.9 vs 31.1) but not in November. Weight-adjusted back-fats depths were lower in both supplemented groups compared to controls (P<0.05). We conclude that simple deficiencies in sulphur-containing amino acids were not limiting for wool production in these grazing sheep. },

For {\textonequarter}M and R sheep born in 1995, the {\textonequarter}M genotype had a lower hogget greasy fleece weight, weaning weight and 12 month live weight.

	abstract = {Skin samples removed from sheep foetuses at weekly intervals during gestation were studied to examine how between breed differences in follicle development are induced. Immunocytochemical methods were used to examine the localisation of the peptide transforming growth factor-Beta1 (TGFb1 ). Our observations indicate general localisation of TGFb1 in the skin between 83 and 104 days of gestation in both Romney and Merino breeds. This coincides with the maturation of primary follicles and the development of sebaceous and sweat glands. TGFb1 immunoreactivity was maintained in primary follicles (particularly the presumptive inner root sheath cells in lower regions of the bulb), sweat gland and sebaceous gland but by day 134, a more discrete localisation was observed in the inner root sheath (IRS), outer root sheath (ORS) and sebaceous gland with intense immunoreactivity in the sweat gland. The timing of the localisation and the lack of difference between the breeds suggest that variation in the TGFb1 level is unlikely to have a regulatory role in primary and secondary follicle initiation but may play a role in regulating the diverse differentiation pattern of various cell types within the follicle. The intense immunoreactivity in mature sweat glands suggests a possible osmoregulatory role for TGFb1 in the skin.   },

	abstract = {Variation in the clean fleece weight (W) between ewe hoggets born in  
1988 from the Massey University fleece weight selected (FW) and control (C)  
flocks was related to variation in four components: predicted skin surface area  
(S), mean number of fibres (follicles) per unit area of skin (N), mean fibre  
cross-sectional area (A) and mean staple length (L).  Mean W ({\textpm}pse) was 3.34  
and 2.48 {\textpm} 0.07 kg for the FW and C lines, respectively.  Of the components, L  
(147 and 126 {\textpm} 3.1 mm; P<0.001), N (29.6 and 27.0 {\textpm} 0.83 fibres/mm2;  
P<0.05) and A (1096 and 1002 {\textpm} 28.0 {\textmu}m2; P<0.05) were significantly greater  
in the FW line (n=27) when compared to the C line (n=22). 
 
The difference in W between the two lines was apportioned into contributions  
from the various components using the percentage deviation technique.  The  
influence of combined components, wool weight per unit area (N x A x L),  
fibre volume (A x L) and total number of fibres (S x N) on W was also  
examined.  The most important contributor to the difference in W between  
lines was L with A and N being less important; the contribution of S was  
relatively small.  Wool weight per unit area had far more influence on 
between line differences in W than wool growing surface area (S) and fibre 
volume was more important than the total fibre number. 
 
Attempts were also made to assess the relative importance of the components  
of fleece weight between sheep within each line.  The standardised partial  
regression coefficients of log transformed values of each component on W  
were; for the selected line, L = 0.26, A = 0.36, N = 0.16, S = 0.38; for the  
control line, L = 0.08, A = 0.58, N = 0.45, S = 0.53.  High values of S relative  
to the other components of W suggest that the size of animal is more important  
in determining the phenotypic differences in fleece weight within the line than  
the genetic differences between lines.

vaginal insertion of CIDR and treated with gonadotrophins for superovulation.   
Of the 12 hoggets 9 had two or more successive plasma samples with > 0.9  
ng/ml progesterone (P4) indicating they had ovarian activity prior to treatment.   
Mean P4 concentrations prior to treatment (d - 3) were 0.69 {\textpm} 0.18 ng/ml and  
had risen to 1.50 ({\textpm} 0.38), 1.72 ({\textpm}0.35), 1.36 ({\textpm}0.11) and 1.31 ({\textpm}0.10) ng/ml

The mean number of follicles and corpora lutea were 5.0 ({\textpm}0.95) and 1.8

an LH peak within 25 hours after CIDR removal.  In addition, those ewes  
treated during late cycle tended (P>0.10) to have a better ovarian response than  
those treated at early or mid cycle.  These results suggest it may be necessary  
to use two CIDR to maintain a sufficiently long period of P4 elevation. In  
addition, the day of the cycle that the CIDR is inserted may be important to  
achieve maximum response from ovulation enhancement treatment in ewe  
hoggets. },

	abstract = {The prenatal development of wool follicles has been described separately  
for the Merino and Romney but a comparative study of both breeds and their  
cross has not been undertaken.  This study compared the rate and timing of  
follicle development in midside skin samples from Romney, Merino and  
Merino-Romney cross (MxR) foetuses slaughtered at weekly intervals from day  
76 to 144 of gestation. 
 
The development pattern of total number of follicles per unit area of skin  
differed between genotypes as indicated by a significant (P<0.001) genotype x  
gestational age interaction.  The total follicle density of each genotype  
increased from day 76 to day 105 at which time the follicle density of the  
Romney peaked at 229 follicles/mm2.  Total follicle density of the MxR  
continued to increase to between 420 and 510 follicles/mm2 between day 104  
and 122 of gestation and the Merino reached a peak of 1170 follicles/mm2 at  
day 125 of gestation.  The density of immature (i) and mature fibre-bearing (f)  
primary follicles (P(f+i)) did not differ (P>0.10) between genotypes over time,  
with each genotype reaching a maximum density of P(f+i) between days 83 and  
90 of gestation.  Primary follicles (P) began to reach maturity by gestational  
day 90 in the MxR and by day 97 in the Merino and the Romney (P>0.10).  In  
all genotypes, secondary follicle (S) initiation began at around day 90 with a  
small proportion starting to form fibres by day 105 of gestation.  There was a  
significant interaction between genotype and gestational age for both the  
density of S(f+i) (P<0.0001) and the density of S(f) (P<0.01).  Specifically, 
S(f+i) increased to 175 follicles/mm2 in the Romney, 440 follicles/mm2 in the 
MxR and 900 follicles/mm2 in the Merino at 105, 105 and 125 days gestation  
respectively, after which S(f+i) density stayed relatively constant up to birth. 
 
These results indicate that follicle initiation and fibre formation in different  
genotypes occurs at similar ages during fetal growth.  The high total follicle  
density in the Merino is due to a high S density which, in turn, is due to S  
initiation continuing for longer than in either the Romney or MxR.  These data  
provide a model for the identification of certain physiological factors which  
affect secondary follicle initiation and development. },

However, at 8 months of age (5 months after cessation of treatment),  
ultrasound backfat depths (Mean{\textpm}SE) were significantly (P<0.05) higher in  
lambs previously treated with excipient (3.4{\textpm}0.3 mm) than in those treated with

Four groups of each breed, consisting of 12 cows per group, were offered pasture allowances of 10, 20, 30 or 40 kg dry matter (DM)/cow/d. In experiment 2, the energy metabolism of 6 Jerseys and 6 Friesians was compared by means of open circuit calorimetry. Energy balances were established for each cow when offered pasture at ad libitum, and at 75\% National Research Council (NRC) requirements. In Experiment 1, on average Friesians produced 26\% more milk, 6\% more milkfat, 13\% more protein and 24\% more lactose. At the lowest level of feeding (10 kg DM allowance/cow/d) Friesians produced more milk but less milkfat and protein than the Jerseys. Friesians consumed more pasture dry matter (av 13\%), lost more live weight and had a lower food conversion efficiency (61 v 67 g milkfat/kg DM consumed) than the Jerseys. It was calculated that milkfat per ha, at a common live weight was lower for the Friesians than Jerseys particularly at high rates of stocking. Partitioning of gross energy into digestible energy or metabolisable energy was not significantly affected by breed in Experiment 2, but the efficiency of utilisation of metabolisable energy for milk and tissue (balance energy) was higher for Jerseys than Friesians (0.58 v 0.48 respectively). The results suggest that in mid lactation Friesians produce more milk and milk solids per cow than do Jerseys because of the greater feed intake of Friesians. In contrast, the higher food conversion efficiency, utilisation of metabolisable energy and dry matter consumption per unit live weight of Jerseys allows them to achieve a higher production per hectare than the Friesians. Comparisons between breeds at other stages of lactation is warranted, particularly in light of current discussions about the system of payment for milk.},

Semen collected and diluted by the New Zealand Dairy Board gave similar conception rates (46\%) to semen collected at Rotomahana (42\%). Results in 1984 indicated that there was a small but non-significant decrease in conception rate with semen storage time up to 15 hours (5 h 68\%, 10 h 61\%, 15 h 57\%). In 1985 there was a highly significant difference between 5 and 20 h storage (46\% v 25\%) and this result was consistent over ewe ages and dose rate. In 1985, 200x10 6 sperm dose was compared to 100x10 6 dose in 3 subtrials. The overall conception rates were 45.7\% and 37.5\% respectively (P<0.05). In 1984 diluted semen stored in glass and inseminated using a fine glass pipette gave a higher, but not significant, conception rate than semen stored in mini straws and inseminated using a standard cattle pistollet (66\% v 58\%). In 1985 all semen was stored in glass and inseminated with either a glass pipette (conception rate of 49.8\%) or a cattle pistollet (43.2\%). This difference was non-significant, although there was a significant interaction of insemination equipment with dose rate. A significantly higher conception rate was achieved for cervical (52.8\%) than blind insemination (29\%) when ewes were inseminated {\textquoteright}on time{\textquoteright} in 1985 and this effect was consistent over dose rate.

All first-order interactions among the effects of storage time, insemination method and {\textquoteright}on-oestrus{\textquoteright} v {\textquoteright} on-time{\textquoteright} were non-significant in the 1984 trial.},
