	abstract = {Three selection experiments, two involving Romneys (at Wallaceville and Ruakura) and the third involving Perendales (at Ruakura), have resulted in breeding lines showing significant divergence in faecal nematode egg count (FEC), under natural challenge. The High and Low FEC lines in each experiment experienced 18, 8 and 11 years of selective breeding respectively to 1996. The geometric means of FEC in the three experiments were 7.3, 2.0 and 4.5 times greater in the High than the Low lines, equivalent to divergences of 2.12, 0.80 and 1.27 phenotypic standard deviations. In the present analysis, the High and Low lines were compared for greasy fleece weights using both yearlings (YFW) and mixed-age ewes (EFW). Relative to the Low lines, the corresponding High lines had greater YFWs by 14.6{\textpm}3.0, 7.9{\textpm}2.4 and 5.3{\textpm}3.1\% respectively (mean of three, 9.1{\textpm}1.6\%), and they had greater EFWs by 14.9{\textpm}1.7, -3.2{\textpm}3.8 and 8.0{\textpm}2.7\% (mean of three, 10.9{\textpm}1.3\%). The conclusion is that single-trait selection for reduced FEC in Romneys and Perendales is associated with reduced greasy fleece weight, when they and less resistant animals graze together. },

	abstract = {A study was carried out in two groups of flocks to estimate the  relationship between susceptibility to facial eczema (FE) and susceptibility  to nematode parasites. Faecal egg count (FEC) data on lambs born in 1989- 92 from 53 sire groups were collected on the Ruakura Romney flocks which  have been divergently selected for resistance/susceptibility to FE. In  addition, the Romney flocks selected at Rotomahana/Tokanui Stations for  resistance/susceptibility to FEC were sampled to provide the converse (i.e.  FE data) on lambs born in 1988 and 1989, and representing 43 sires. Faecal  samples for FEC were collected from lambs in January and March  (separated by an anthelmintic treatment) and the FEC data were analysed  using a loge transformation. FE susceptibilities, using the enzyme gamma- glutamyltransferase (GGT) as an indicator, were obtained in the FE flocks at  Ruakura after an oral sporidesmin challenge in May, and in the FEC flocks  at Tokanui after unintentional field challenge; the GGT data were also  analysed using a loge transformation. The weighted average heritabilities of  loge GGT and loge (FEC+100) were 0.44},

The characteristics of standard  curves and the precision of measurements were comparable between the EIAs  and corresponding radioimmunoassays (RIAs). The applicability of the EIAs  was demonstrated by using them to measure oestradiol-17b and progesterone  concentrations in media sampled daily from cultures of bovine granulosa cells.   The EIAs detected the characteristic switch in cellular steroidogenic capacity  from oestradiol-17b to progesterone production typical of cultured granulosa  cells. There was a significant linear correlation (P<0.001) between the EIAs  and RIAs in the concentrations of steroids measured in granulosa cell culture  medium by the two immunoassay formats. These findings may encourage  other laboratories to consider converting "in-house" RIAs to EIAs, thereby  eliminating the potential health and environmental hazards associated with the  radioisotopes required for RIA.  },

	abstract = {Four trials involving the intra-uterine insemination of a total of 840 Coopworth ewes were conducted to assess the fertilization capacity of ram semen stored at 15 C. Semen from Polled Dorset rams was collected by artificial vagina, diluted with either a standard milk diluent or a synthetic diluent (RSD-1) to a concentration of 200x10 6 sperm/ml, cooled to 15 C, placed in 0.25 ml straws and held at 15 C for various periods [Day 0 (4h), Day 1 (28 h), Day 2 (52 h), Day 3 (76 h) and Day 4 (100 h)] before insemination. Ewes were synchronised, with CIDR devices inserted for 14 days and 400 i.u. PMSG was given at time of device removal. Laparoscopic assisted intra-uterine inseminations were performed between 52 h and 56 h after device withdrawal. A total of six inseminators were used throughout the trial series with between 3 to 5 inseminators per trial. Conception rates were determined by plasma progesterone levels at day 19 and pregnancy confirmed by real time ultrasonic scanning at day 50 post mating. There were significant differences between trials in the proportion of ewes treated that exhibited oestrus prior to insemination with lower percentages in the non-breeding season. There was considerable discrepancy between the two methods of pregnancy detection. A high proportion of the non-tupped ewes deemed pregnant by progesterone were not pregnant at scanning. There were no differences between trials in the proportion of ewes pregnant after insemination with Day 0 semen. There were no significant differences between the diluents at any particular time of storage however, the overall pregnancy rate was higher for the milk diluent (50.1\% v 45.0\%). There was a significant effect of storage time, with the mean overall values for storage periods of 0, 1, 2, 3 and 4 days being 49.4 46.5, 40.3, 29.6 and 20.0\% respectively. Significant differences between inseminations were recorded ranging from 52.6\% to 35.0\%. The similarity in conception rates between diluents to different storage times is in marked contrast to the estimations of percentage motile sperm obtained with these treatments. This indicates that further modification of the diluent is necessary and that for this to be achieved more critical and quantitative measurements of sperm motility and function are required.},

	abstract = {The aim of this study was to gain evidence that the FecB and FecXI genes influence ovarian development in foetal life. Foetuses which were homozygous carriers of the Booroola gene (BB), Inverdale gene (II), heterozygous carriers of the Inverdale gene (I+) and non-carriers of both the Booroola (++) and Inverdale genes (++) were recovered at days 40 or 90 of gestation. To eliminate the effects of litter size in the Booroola study, equal numbers of BB and ++ embryos were transferred to recipient ewes.  Subsequently no gene-specific differences in litter size were noted at the equivalent of days 40 and 90 of gestation. From these studies the FecB gene was shown to affect body weight, the weight of the mesonephros, and development of germ cells. In essence, at day 40 the mean body weight and mean weight of the mesonephros were lighter in the BB foetuses compared to the ++ animals (P<0.05). Moreover the development of the BB ovaries appeared to be retarded relative to that of the ++ ovaries with respect to mitosis and meiosis of germ cells and also the timing of germ cell atresia. In the Inverdale foetuses, which were recovered after natural matings, differences were observed at the level of the ovary but none were noted with respect to body weight, or weight of mesonephros. At day 40 of gestation the ovaries of the putative II foetuses were significantly lighter (P<0.05) than those of the I+ or control animals. Moreover at day 90 the ++ and putative II ovaries contained significantly fewer (P<0.05) germ cells (i.e. ~110,000) compared to those in the authentic or putative I+ animals (i.e. ~240,000).  The differences in either the Booroola or Inverdale foetuses were not accompanied by any significant differences in plasma or pituitary concentrations of follicle-stimulating hormone or plasma inhibin. The results are consistent with the notion that the FecB and FecX genes influence ovarian development in foetal life.},

The aims of this paper are to report on genetic parameters for age at first oestrus (AFO) in heifers, weight at first oestrus (WFO) in heifers, scrotal circumference (SC), 13-month weight (W13) and calving day (CD), to compare the performance of young animals in the selection and control herds, and to assess prospects of achieving a correlated response in calving rate.  Three selection herds and a control were set up, with single selection objectives being SC, AGE+ and AGE-, where {\textquoteright}+{\textquoteright} and {\textquoteright}-{\textquoteright} indicate selection for greater or lesser AFO. Phenotypic coefficients of variation were 15\% for AFO, 11\% for WFO, 8\% for SC, and 8\% for W13. Corresponding heritability estimates from Waikeria were 0.15, 0.30, 0.24 and 0.33, compared with those from other New Zealand research herds which averaged 0.34, 0.37, 0.38 and 0.36 respectively. The genetic correlation estimate for AFO and SC was - 0.81},

	abstract = {This study was undertaken to investigate the effects of time from CIDR withdrawal and ewe age on conception rates in a sheep artificial insemination programme. Four groups each of 50 Romney ewes (balanced for ewe age, two-tooths vs mixed age) were synchronised by intravaginal insertion of CIDRs for 11 days. Ewes in each group were inseminated at 36h, 42h, 48h or 54h respectively from CIDR withdrawal by cervical insemination using 200 million sperm per insemination of fresh semen. Conception was determined by measuring non-return rates using harnessed rams. Conception rates increased (P<0.10) with the interval between CIDR withdrawal and fixed time insemination thus: 36h, 37\%; 42h, 49\%; 48h, 59\%; and 54h, 60\%. Conception rates were greater in mixed age ewes (58\%) than in two tooth ewes (43\%) (P<0.05). There was no interaction between the effects of age and time of insemination relative to CIDR withdrawal. It is concluded that there may be advantages in extending the interval between CIDR withdrawal and insemination to 48 to 54 h as opposed to the current industry recommendations of 45 to 48 hours.},

Autumn liveweight  gains were not significantly different averaging 44g/hd/day. Carrying  capacity was lowest on lotus pastures in all seasons. White clover  pastures had the highest carrying capacity in all seasons though only  significantly greater than red clover in autumn. No differences in  total animal production per hectare were found in spring. Red clover,  however, had 45\% more animal production in summer than white clover or  lotus pastures. This increased production was attributed to a greater  consumption of legume due to both the dominance of red clover in the  upper sward horizons and an active selection of red clover by the goats.  },

There was a positive relationship between the  calpastatin : calpain I ratio and protein degradation and a negative  relationship with calpain I. This result is at variance with the idea  that calpain I activity limits the rate of protein degradation.  },

	abstract = {A selection experiment at Waikite (Rotorua) began in 1971 with closed Angus herds selected for adjusted 13-month weight (AS1), adjusted 18-month weight (AS2) or with random replacement (ACO). A closed Hereford herd, selected for adjusted 13-month eight (HS1), was also established. At both 13 and 18 months of age, annual responses in live weight in the AS1, HS1 and AS2 herds averaged 0.96, 0.62 and 0.48\% of the ACO herd means (calvings 1972-85). Five correlated responses were estimated. 1. Cow weight: From all ages of cows recorded over 4 seasons (on average 11 years of selection completed), AS1 and AS2 cows were 7.5 and 8.2\% heavier respectively than ACO cows; HS1 cows were 2.5\% heavier than AS1 cows, the same margin as in 1971. 2. Maternal weaning weight: (AS1 and AS2 herds only, relative to ACO): responses was estimated in a tester herd from calvings in 1982-86. The maternal grandsires were selected AS1 and AS2 bulls born after almost 2 generations (6 years) of selection. The AS1 herd was superior by 8.6 kg (5.7\%) and the AS2 herd by 2.2 kg (1.5\%). 3. Scrotal circumference: From the 1982-85 crops, the AS1 and AS2 bulls had respectively 0.9 (P<0.01) and 0.3 cm larger circumferences at 13 months of age and 0.7 (P<0.01) and 0.4 cm below corresponding AS1 values. 4. Height at withers: AS1 and AS2 bulls from the 1981 calf crop were respectively 3.5 and 2.5 cm taller (P<0.05) than the ACO bulls; the HS1 bulls were 2.3 cm taller (P<0.05) than the AS1 bulls. 5. Food intake: Average intake of silage by Angus bulls from the 1980 and 1981 crops were 10.4\% and 11.7\% greater (P<0.01) for AS1 and AS2 than ACO cattle respectively. Expressed relative to body weight, there was no significant difference due to herd. The pooled regression of daily intake of dry matter on 18-month weight was 0.0091 kg/kg (P<0.05), with a correlation of 0.32. The correlations of pre-fasting plasma tryptophan and the fall in plasma tryptophan concentration with average previous intake were 0.50 and 0.41, for bulls fasted over a 48 h period.},

Two perennial ryegrass cultivars, selected on the basis of leaf shear strength (LS and HS) were fed to Romney wethers in May and October 1988 indoors for 2 weeks to measure voluntary intakes. Higher daily intakes of LS than HS (102 gDM/kg0.75 v 86 gDM/kg0.75) were recorded in October, but no significant differences were observed in May, apparently as a result of high amounts of dead matter in the herbage. Eight rumen fistulated wethers were fed either LS or HS cultivars in May. Cr-EDTA-Ru-phenanthroline marker solution was infused for 6 days to measure rumen outflow and total faecal collection was made for digestibility determination in May. Total faecal collection was also made in October following the measurement of voluntary intake. In both experimental periods eating behaviour was also recorded. Low digestibilities were observed in May with no significant differences between LS and HS (65\% v 67\%), but in October high digestibility of HS than LS was observed (76\% v 73\%), and also longer rumination times for sheep fed HS than LS were recorded in October (542 min/kg/DM/day v 426 min/kgDM/day). The rate of DM disappearance of herbages containing low amount of dead matter (8\%) when suspended in the rumen of cows, was significantly greater for LS than HS.
