There appears to be a west to east cline in the four north Wales counties in: (i) the proportion of calves sold during the autumn months September to December; (ii) the proportion of December milk sales in relation to the September sales; (iii) the proportion of the dairy and breeding herd in milk during the winter; (iv) the quarterly rates of conception in heifers during the period 4 December to 4 March. There does not appear to be any relation between percentage winter milk production and percentage tillage area in this region. It is postulated that the west to east cline is dependent mainly upon factors other than husbandry and that climatic conditions, particularly the hours of bright sunshine during the winter months, have a marked influence upon the breeding performance of cows and heifers during the period December to March.This investigation has formed part of the survey of animal health and production in Wales, and thanks are due to the scientific branch of Messrs Cooper, McDougall and Robertson, Berkhamsted, for financial support. Grateful acknowledgement is made to the Ministry of Food, Colwyn Bay, for readiness in providing data and helpful advice; to Messrs Pritchard, Auctioneers, Bangor, and Messrs Beardmore, Auctioneers, Abergele, for permission to examine their records; to the Milk Marketing Board for providing the data on milk sales; to Profs. A. N. Worden and E. G. Bowen for the interest they have taken in the work.

The distribution of Mesolithic sites in Wales is controlled to a great extent by the terrain, for physiographically, Wales is a highland block defined on three sides by the sea and for the greater part of the fourth side by a sharp break of slope. Geologically the Principality is composed almost entirely of Palaeozoic rocks, of which the 600-foot contour encloses more than three quarters of the total area. There are extensive regions above 1,500 feet and 2,000 feet and in the north the peaks of Snowdonia and Cader Idris rise to 3,560 feet and 2,929 feet respectively. Indeed North Wales consists of an inhospitable highland massif, skirted by a lowland plateau and cut deeply by river valleys, providing only limited areas for settlement. The hills and mountains of Snowdonia with their extension at lower altitudes into the Lleyn Peninsula, and the ranges of Moelwyn, Manod Mawr, Arenig Fach and Cader Idris, are discouraging obstacles to penetration, save for a short distance along the river valleys. To the east of these peaks are extensive tracts of upland plateau dissected by rivers, bounded on the west by the vale of the river Conway and cleft by the Vale of Clwyd. To the east of this valley lies the Clwydian Range and further again to the east these uplands descend with milder contours to the Cheshire and Shropshire plains.To the south the district merges into the uplands of Central Wales, which are continuous until they are replaced by the lowland belt of South Wales.


Dairy farming is vulnerable to seasonal variable factors such as temperature, cold climatic conditions, and rainfall. These affect the production and reproduction traits of dairy animals. Seasonal variability also affects the quantity of consumption and marketing of milk considerably. The study aimed to assess the seasonal fluctuation in milk production in Sivagangai District Cooperative Milk Producer Union Limited (SDCMPUL), Tamil Nadu. The study used secondary data. The milk production data were collected from SDCMPUL, Karaikudi, Tamil Nadu. The data covered the period from 2001-02 to 2020-21. The study used descriptive statistics, CAGR, and paired ‘t-test to determine the variation of milk production according to seasonal changes. The MS office - Excel software and SPSS software were used to analyse the data. The results revealed that the mean milk production of the lean and flush season was 2.46 and 2.30 lakh liters, and the CAGR of milk production in SDCMPUL, Tamil Nadu, during the period 2001-02 to 2020-21 was 5.65 percent, and it was 5.23 percent in lean season and 6.11 percent in the flush season while the growth rate of milk production during the lean and flush season was positive and was significant statistically. It was found that the quantity of milk production was higher in the lean season than a flush season; however, the variability of milk production was more in the flush season than in the lean season.

The paper presents the study results of Vigainavolok I materials. This settlement is located on the west of Lake Onega in Karelia. The monument was investigated by G.A. Pankrushev in 1963-1966. Its area was 8,000 m. 26 buildings remains were revealed. The area of 2748 m was studied. The inventory collection includes more than 25 thousand pieces of ceramics and about 7 thousand pieces of stone, clay and metal. The buildings served as dwellings and workshops. The collection includes sinkers that are marked as direct signs of fishing. Favorable climatic conditions for the development in the forest zone, confined to the coast of a large body of water, settlement equipment, osteological materials of the Stone Age monuments characterize fishing as one of the determining factors in the life of the population.

Recent studies confirms the fact that Abrosia artemisifolia L. sin A.elatior., specie has spread from the west of the country to the central; and south areas, invading agricol crops, provoking great production losses if the intervention in not efficient and made in due time. In the present paper there are presented the effect of several tested herbicides in different phases of vegetation, in climatic conditions of 2006-2007.

The objective of this study was to evaluate the economic impact of supplementing dairy cows with mixtures of polyherbal products supplying conjugates of choline (BioCholine, BC), lysine (OptiLysine, L) and methionine (OptiMethionine, M), considering the costs of veterinary treatments, the nutraceutical effects of the mixtures, the partial cost and returns of milk production. Eighty postpartum Holstein cows were randomly assigned to individually receive. The pellets no containing (Control, 20 cows) and containing polyherbal products (g/d) (BC20, 19 cows; BC40, 17 cows; BC20+L40+M20, 12 cows, and BC40+L80+M40, 12 cows) were offered to cows during the milking through automatic feeders in the course of 90 days in a commercial farm. Treatment costs were grouped in terms of antibiotics, healing, anti-inflammatories, glucogenics, hormonal, intra-mammary treatments, restorative and vitamins. Milk production was not affected (P>0.05) by polyherbal additives but there were numerical differences in the number of treatments and costs; animal health cost per cow showed a high variation coefficient (average 347%). Cows receiving BC40 and BC20+L40+M20 had reduced animal health cost per cow but only the treatment BC40 showed residual effects post experiment with an economic improvement of 2.1% over the control group, showing benefits associated to a reduction in the number of doses with antibiotics and doses of immune-stimulants. Cows receiving BC40 had the best milk yield numerically in combination with the lower number of animal health costs which resulted in the highest income.

On 29th November 1950 workmen employed by the Merseyside and North Wales Electricity Board were relaying a cable on the west side of Castle Esplanade, Chester. In cleaning up the western side of the trench with a spade, 18 in. below the present pavement level and 29 ft. to the south of St. Martin's Court, one of the men cut through a small earthenware vessel and a shower of coins and silver bullion poured into the bottom of the trench. It is distressing to record that although the Grosvenor Museum is only 100 yards from the site, the discovery was not reported. No significance was attached to the find; one of the men stated later that they thought they were milk checks. Three of the men put handfuls of coins into their pockets; others were distributed to children near, and the rest shovelled back into the trench. The engineer-in-charge took several to his office for thepurpose of identification, but later forgot about them. One of the men sent some of the coins to Hunter Street Girls' School, by his niece, for identification, and the mistress immediately sent them to the Curator of the Grosvenor Museum.This happened on 10th December, and the Curator at once appreciating the significance of the discovery, set to work to recover as much as possible of the hoard, and reported the matter to the City Coroner. As a result he recovered a hundred coins, twelve ingots of silver, and a fragment of the vessel.

ABSTRACTA carved coping stone found on the site of a spring near the amphitheatre, Silchester, and first reported in 1873, was rediscovered in 2014. It does not compare in its carved detail with coping stones from the amphitheatres at Chester and London, nor with that recovered from the West Gate, Silchester, in 1890; nor does its basal width correspond with that of the arena wall of the Silchester amphitheatre. It is likely to have formed part of a monumental basin, similar to that found at Coventina's Well, Northumberland, and to have commemorated the location of a spring and its associated (unknown) deity. Similarity with the type and decoration of architectural stone used in the construction of the forum-basilica suggests a Hadrianic–Antonine date.

The pattern and character of Northern Ireland farming is to-day very different from what it was a century ago. The farms, although still relatively small, were then very much smaller, and the output of farm products was very low. The changes in farm organisation consequent upon the gradual increase in the size of farms made it possible for the occupiers to keep more stock. Indeed, the tendency to-day for consolidation of holdings into larger units is being accentuated by economic conditions and developments in farm mechanisation.Climatic conditions have also played a big part in the expansion of stock farming. While the rainfall cannot be regarded as excessive, at least in the east, it tends to be unduly persistent in the harvest months so that crop production, especially of cereals, is a risky business. In the west, with a higher rainfall, it is even more so. This enforced limitation of cropping has induced farmers to concentrate more on the production of livestock and their associated products.

Abstract The Great Oxidation Event (GOE) is marked by the loss of readily oxidizable detrital minerals and the onset of oxidative weathering. One of the oldest post-GOE weathering surfaces, which extends for almost 350 km along strike, occurs in Griqualand West, South Africa. It is best preserved east of the Blackridge thrust, where oxidized paleoweathering profiles are developed below the unconformity at the base of Mapedi-Gamagara red beds. In the Maremane Dome, the red beds preserve pisolitic hematite laterites, which indicate a highly oxygenated atmosphere and suggest hot and humid climatic conditions. The Mapedi and Gamagara Formations are undated east of the Blackridge thrust but were thought to be lithological correlatives of the ≥1.91 Ga Mapedi red bed sequence to the west. Here, we report a U-Pb zircon age of 1.25 Ga for a felsic tuff in red beds of the Mapedi Formation in the Kalahari manganese field. The new tuff age shows that the Mapedi red beds east of the thrust were deposited >650 m.y. after the Mapedi Formation to the west, and therefore they are part of a distinct Mesoproterozoic sequence. Based on lithologic and sedimentological similarities, the Mapedi-east and Gamagara formations are likely to be correlatives that were deposited on an ancient weathering surface at ca. 1.25 Ga. Our findings suggest that key evidence for a highly oxygenated atmosphere during the early Paleoproterozoic actually formed at ca. 1.25 Ga during a major episode of Mesoproterozoic oxidative weathering.
