REASONS FOR PERFORMING STUDY In horses, aortic sinus of Valsalva aneurysms or tears in the aortic root are well-recognised conditions in breeding stallions, often leading to sudden death. A more uncommon form of aortic rupture, located proximal to the ligamentum arteriosum has been reported in 3 Friesian horses. OBJECTIVES The purpose of this study was to phenotypically characterise aortic ru...
Five Chios and five Friesian rams were used to study the effect of season on semen production. Semen samples were collected with an artificial vagina. In spite of the large variation of most of the semen characteristics among rams of the two breeds, seasonal variation in semen quantity (volume, concentration and total number of spermatozoa per ejaculate) and quality (percentage of motile sperma...
Milk performance (protein and fat content) and milk fatty acids (FA) profile of dairy cows under supplementation with two sources of concentrate, oilseeds (C, cottonseed) at two levels, low (5kg DM/cow/day) and high (7 kg DM/cow/day), and cereal grains (B, barley) at high rate (7 kg DM/cow/day), were studied in three herds (n=36) of spring calving Holstein-Friesian dairy cows (200 days in milk)...
Hydrocephalus is uncommon in horses. However, in recent years, it has become clear that the prevalence of hydrocephalus is greater in Friesian horses than in other breeds probably due to their limited gene pool. Before identification of candidate genes that predispose to the development of hydrocephalus in Friesian horses can be pursued, an in-depth, phenotypic, pathological description of the ...
BACKGROUND Thoracic aortic rupture and aortopulmonary fistulation are rare conditions in horses. It mainly affects Friesian horses. Intrinsic differences in biomechanical properties of the aortic wall might predispose this breed. The biomechanical and biochemical properties of the thoracic aorta were characterized in warmblood horses, unaffected Friesian horses and Friesians with aortic rupture...
To determine whether long-term administration of growth hormone (GH)-releasing factor (GRF) and(or) thyrotropin-releasing hormone (TRH) alters ovarian follicular fluid (FFL) concentrations of insulin-like growth factor-I (IGF-I), progesterone, and estradiol (E2), and follicular growth, Friesian x Hereford heifers (n = 47; 346 +/- 3 kg) were divided into the following four groups: control (vehic...
Phenotypic characterization of Bunaji (White Fulani) and Bunaji x Friesian breed cattle of the institutional herd of National Animal Production Research Institute (NAPRI) Shika; Kaduna State, Nigeria was carried out for the purpose of comparism. A total of 163 cattle were used comprising 20 Bunaji Bulls, 106 Bunaji cows and 37 Bunaji x Friesian. Data measured directly from the animals in the he...
TCP-nets are an extension of CP-nets which allow the expression of conditional relative importance of pairs of variables. In this paper it is shown that a simple logic of conditional preferences can be used to express TCP-net orders, as well as being able to represent much stronger statements of importance than TCP-nets allow. The paper derives various sufficient conditions for a subset of the ...
The synaptonemal complex (SC) was analyzed in four F, hybrids of Bos taurus taurus and B. faurus zndicus including Gyr-Simmental (G-S), Nelore Simmental (N-S), Gyr-Holstein-Friesian (G-H) and Nelore-Piemontese (N-P). We analysed the frequency of various types of SC abnormalities and the frequency of cells with SC abnormalities. The results were compared with similar observations made on purebre...
