	abstract = {A series of 4 herbage allowance trials was conducted over 2 years with beef cattle on a well-drained site in Northland. Two trials were conducted in autumn/winter (April-July) and 2 in spring (October and November). Analysis of the data, for each seasonal period combined over the 2 years, showed large differences in the relationships between daily live- weight gain and herbage allowance between the 2 seasons. At the same allowance, beef cattle grew faster in spring than in autumn/winter. Relationships between allowance and daily live-weight gain were: Autumn/winter: LWG = 0.48-1.37* 0.65 allowance Spring:    LWG = 1.09-2.82* 0.45 allowance These differences were not associated with differences in in vitro digestibility (70 to 78\% in all trials) or N concentrations. Allowances required for maintenance were lower in spring than in autumn/winter and potential growth rates in spring approximately double those in autumn.},

	abstract = {The relationship between maternal behaviour and ewe productivity was determined by least squares analyses of records for 1 year on 1050 ewes of 6 genotypes and 3 age groups. A 1 to 5 score was assigned to each ewe based on observations during tagging of lambs within 24 h of birth. Maternal behaviour was better (by 0.26 score) in 6-tooth (6th) than 4th ewes which had a score 0.27 units higher than 2th ewes. Maternal behaviour score increased by 0.18 for each unit increase in litter size (range 1 to 4). When the effect of litter size on maternal behaviour was removed, ewe genotype differences in maternal behaviour score were small. Lambs weaned/lambs born, corrected for litter size, age and genotype of ewe, increased by 0.06 for each unit increase in ewe behaviour score. The rate of increase was greater within high litter sizes. Weight of lamb weaned/ewe lambing was higher for ewes with higher scores for maternal behaviour.},

	abstract = {The soil type is an important factor influencing the occurrence of trace element deficiencies in grazing animals in New Zealand. Cobalt and selenium deficiencies occur mainly on soils from acidic rocks. Cobalt deficiencies may also occur on soils from more basic parent materials where the soils have been strongly leached. Selenium deficiencies is less easily predicted on the basis of soil characteristics. Copper deficiencies are more likely in stock grazing on peat soils, gley soils, certain pumice soils, saline soils, recent soils and some steepland soils. For all 3 elements, classification of occurrences of deficiency by soil type has provided a basis for delineating areas where deficiencies are likely, areas where they are unlikely and areas of marginal status. This has enabled a rational approach to investigations and the application of treatment and control measures.},

	abstract = {The effects on two-tooth reproduction of 3 times of shearing relative to joining either in early March or early April were investigated. Ewes were shorn either 4 or 2 weeks before joining or remained unshorn throughout. Ewe fertility was increased by shearing 4 weeks before joining compared with the other shearing treatments. Joining ewes in April increased fertility. It is concluded that ewes should be shorn at least 4 weeks before joining and joined in April rather than March if lamb production is to be maximised.},

	abstract = {Two experiments involving 715 suckling beef cows were conducted to determine the effects of oestrogen treatment at the time of PRID insertion on the synchronisation of oestrus and conception rate to timed AI. Experiment 1 examined the route of administration and dose level of oestrogen while Experiment 2 studied the effect of oestrogen treatment at PRID insertion and/or an injection of prostaglandin at the time of PRID removal. Treatment with oestrogen resulted in an 18\% improvement in synchrony and a 9\% increase in conception rate. A dose level of oestrogen 4 times that given by intramuscular injection was required to achieve similar results when it was administered via a gelatine capsule attached to the PRID.},
