ABSTRACT
The frequency of mammary neoplasia in different species
varies tremendously. Among women, breast cancer features as one of the most
frequent types of cancer globally. Breast cancer is the cause of almost half
a million deaths worldwide each year. Of these deaths, more than 58 % are
occurring in developing countries. Mammary tumors are rare in cows, mares,
goats, ewes, and sows as evident by few cases reported in literature. In
dairy cattle and milking goats the udders are inspected daily by palpation
when milking and the tumors would be detected soon. The morphological
features of bovine mammary gland are more similar to those in human than in
rodents, the latter being commonly used for cancerogenic studies. There are
several factors that might affect the high rate of tumor development in
women and attenuate the development of tumors in ruminants. Besides diet,
life style, reproductive history, stress load, the general physiology and
metabolism might have an influence. Translational research using different
mammary gland cell populations from several species may lead to comparative
studies and may help reduce the risk and contribute to discovery of new
therapeutic targets to treat breast cancer. In present work the zero
occurrence of mammary gland tumors in ruminants will be reviewed focusing on
literature records and mechanisms underlying the resistance.

ABSTRACT
This paper reconsiders the reliability of the results
obtained by Hristov et al. (2012) from the input-output analysis of
water consumption, by taking into account the effect of uncertainty inherent
in the data. The imprecision and uncertainty is studied within a workable
fuzzy environment as introduced by Beynon et al. (2005), where rank
reversal is plausible. In addition, the water-intensive structure of the
Macedonian economy is investigated by applying Dietzenbacher eigenvector
methodology (1992). As suggested in the analysis of Hristov et al.
(2012), the water-intensive structure of the economy in Macedonia is
confirmed as being mainly focused on agriculture and several industrial
sectors, given that rank reversal is absent. Consequently, there is a need
to introduce changes in the agricultural production technology as well as
the specialization of production in this region.

ABSTRACT
Total 80 Sanjabi ewes (2–5 years old and 50–85 weight
domain) were selected in animal unit of Mehregan farm. The ewes were divided
to 4 treatment groups according to body condition score of (2, 2.5, 3,
3.5 ≤). Blood samples were collected from non-pregnant ewes, then after
mating, two weeks before expected lambing and at lambing day. Blood samples
of newborn lambs were also taken from the jugular vein at birth and 7 days
of age. The reproductive parameters such as number of lambs born per
lambing, kg of lambs born per ewes mating, pregnancy period and lamb birth
weight were determined. Some blood metabolites such as glucose, total
protein, albumin and globulin were determined. The white blood cell and
differential leukocyte counts were also measured. The result of this
experiment indicated that BCS = 3 had a significant effect (P < 0.05) on the
kg lambs born per ewes. Ewes with BCS = 3 had a better performance in the
percentage of lambs born per ewes at mating, while the lambing rate reduced
in ewes with BCS of 3.5 or more. Birth weight of lambs was significantly
affected by BCS of their ewes (P < 0.05). There was a significant effect of
BCS on plasma FSH concentration in ewes with BCS more than 3 but no
significant difference was seen in blood metabolite in this study. Colostrum
productions and the lamb birth weights were affected by body condition score
of ewes. The white blood cell counts, neutrophils and lymphocytes counts did
not change between ewes and lambs. It is concluded that BCS had a
significant effect on kg lambs born per ewes, birth weight of lambs, lambs
weaning weight and colostrum productions (P < 0.05) and the score of 3 at
mating time could optimize profitability of Sanjabi ewes.

ABSTRACT
Valvasor reported in 1689 about rearing horses in
Carniola region. In some passages of the book “The Glory of the Duchy of
Carniola” he was writing also about the Karst horse. Other horse breeds,
mentioned in the publications until 1945 are the Noric horse, Lipizzan
horse, Belgian horse, Ljutomer trotter, Međimurje horse and other breeds. By
directive of the Ministry of Agriculture, the former Dravska Banovina, was
in 1934 divided into the region of cold-blooded horses with three districts
(Međimurje horse, medium heavy Noric horse, light Noric horse) and in two
districts with warmblood horses (American racer and Lipizzaner). The Karst
horse was mentioned in the historical records from 1582. These horses were
strong animals famous for their longevity. The Karst horse breed is the old
Slovenian breed, which directly participated in the formation of the
Lipizzan horse from the 16. century onwards. The breed is extinct now. The
Bohinj horse was tall, broad and powerful. The breed was first mentioned by
Dr. Bleiweis in 1855. The origin of the breed dates in the early 18 century.
The domestic mares were crossbreed with stallions of Nonius breed (Hungarian
stallions). With the introduction of heavy Norican stallions the original
Bohinj horse disappeared. The Kobarid horse was a strong draft horse breed,
previously bred in the Soška dolina and on its outskirts. The breed was
highly appreciated also in the Friuli region. The First World War ruined the
breed structure, and there is no available information about the Kobarid
horse since 1928. The Posavinje horse was also called Savinje horse and was
raised in Savinjska dolina. It was developed by crossing the Noric horse and
Ardenes horse breeds. This medium heavy breed of horse is extinct too.

ABSTRACT
The original pigs were usually declaired in the
literature as domestic, natural, ordinary, black or named by its origin like
Carnolian, Styrian, Solčava, Krškopolje pigs. With the start of pig
breeding, the local pig breed was developed in Carniola region. The source
were partly local pigs, greatest influence had Croatian-hungarian breeds,
which were progressively crossbred, especially with an English Large White
breed. Local breed was resistant, having high legs, flat snout and strong
back. Pigs from the Carniola region, Croatian pigs, German breeds, British
breeds (especially Yorkshire) and Krškopolje pigs were used to upgrade local
population of black spotted pigs in Gorenjska region, however, the role of
each breed can not be well determined. The breed was characterised as
meaty-faty type. Its animals had relatively high growth capacity and good
quality of meat. Their resistance and modesty to the rearing conditions were
highly appreciated. Due to growing market demand for meaty breeds, the breed
was inevitably abandoned. Only few notices were found for the black pig
breeds from Solčava and Styria region. The breeds were resistant and modest.
The both breeds were extinct.
