	abstract = {Thirty-eight adult Merino breeding ewes were drenched with Ivomec  and given a controlled release anthelmintic (benzimidazole) capsule in  August 1992 and December 1993.   Mean FEC in the Untreated group peaked over lambing at 600epg in 1992  and 800epg in 1993. Mean FEC in the Treated group remained below 50epg  during the active period of the capsule. The Treated ewes had a higher  survival rate, were heavier, grew more wool from late July 1993 and weaned  more and heavier lambs in 1993 than the Untreated ewes.   At a mean Merino wool price of 500c/kg greasy, returns from the increased  wool production more than equates with the anthelmintic treatment cost.   Increased returns would be gained from improve ewe survival and increased  lamb production.  },

	abstract = {Lambs grazing ryegrass infected with endophyte (Acremonium lolii) may exhibit staggers or diarrhoea or both, with little correlation between these two conditions. Associated mycotoxins/toxins other than the staggers-inducing lolitrems are likely to be responsible for metabolic changes causing reduced intake, elevated temperature and diarrhoea. These mycotoxins are not necessarily confined to the base of the leaf sheath and stem as is the case for lolitrems. The distribution of mycotoxins to proximal portions of vegetative ryegrass and the effect of these plant components on grazing animals was investigated. Following experimental confirmation in 1991 of nil correlation between staggers and diarrhoea, groups of lambs were grazed in autumn 1992 on 100\% endophyte-infected hybrid ryegrass cv. Grasslands Marsden (Lollium boucheanum Kunth.), using a leader-follower system. Upper and lower leaves, and pseudostem were progressively removed by four groups of lambs on three day breaks, replicated twice. Liveweight gain ranged from 164 g/day in lambs having first offer, to 28 g/day in those grazing the base of the plants (P<0.01). Rectal temperature averaged 40.2 C being slightly above normal in all treatments. Faecal moisture was high; ranging from 79-87\% throughout the experiment with no significant differences due to treatment. Observed faecal soiling was greatest in lambs receiving high leaf component (P<0.05). Clinical staggers, barely detectable in lambs grazing leaf, became severe as the proportion of pseudostem in the diet increased (P<0.01). In contrast to the clear association between endophyte and staggers in lambs grazing the base of infected ryegrass, consistently high faecal moisture, and consequent faecal soiling occurred regardless of the part of the plant consumed, but tended to be greatest in lambs grazing leaf. Analysis of plant components suggested that peramines may be associated with this problem.},

	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.},

	abstract = {Fat and lean Coopworth ewes that were daughters of fat and lean rams were joined with rams from the Invermay lean and fat selection lines to study the effects of genotype (fat, lean) and mid-pregnancy feeding level on foetal weight and ewe carcass measurements at day 135 of gestation. Ewes offered a high level of feed during days 30 to 100 of gestation gained 3\% while those on a low level lost 9\% of their day 30 live weight. All ewes were offered the same level of feeding from day 100 until slaughter on day 135. Mid-pregnancy nutrition had no effect on foetal weight. Litter size had significant effects on foetal weight (single 4.56 kg, twin 3.99 kg, triplet 3.24 kg). The weight of foetuses of the lean genotype adjusted for litter size and nutrition was 270g heavier (P<0.01) than that of the fat genotype. The weight of placenta, and placentome number/foetus decreased with litter size and were associated significantly with foetal weight. Fat genotype, however, had no effect on placental weight or placentome number. Fat genotype of the ewe and foetus did not affect a number of foetal skeletal size parameters but influenced foetal weight despite ewe nutrition. Consequently it appears that this influence on foetal weight is independent on any effect of the placenta per se.},
