Istraživanje je provedeno na uzorcima mišićnog tkiva (but i plećka) i jetre junadi u dobi od 9 do 12 mjeseci koja su tovljena ekstenzivno (n=12) ili intenzivno (n=12). Svaki uzorak je podijeljen na dva jednaka dijela od kojih je jedan analiziran u sirovom stanju, a drugi nakon termičke obrade kuhanjem u vodi na 100°C. Rezultati su iskazani u apsolutno suhoj tvari mesa.

The dairy sector, including primary animal products and processed dairy foods, is a core sector for agricultural development. In 2006 the agriculture sector contributed about 10.4% of GDP, in 2008 8.4%, 2009 7.8%, 2011 8.7% and 2012 8.2%. Dairy farming dominates agricultural production and total livestock production contributes almost 60% of agricultural GDP. Milk production should be primarily directed towards cheaper and better quality of products. This is possible with active credit lines, more investment in the modernization and expansion of existing production capacity, as well as with construction of new large specialized farms, and new technologies, especially in the way of housing and handling of animals, nutrition, hygiene, etc. Current work is a brief review of the dairy sector at the past quarter century prepared by using data from different sources.

During four weeks of the experiment 64 Wistar rats were divided into four groups of 16 individuals each (eight individuals of both sexes) and fed a commercial feed mixture for rats (group C) or diet containing 70% commercial mixture for rats and 30% freshly cooked egg yolks from laying hens fed diets with 3% fish oil (group F), 3% palm olein (group P) or 3% lard (group L). Dietary supplementation with egg yolks significantly increased the hepatic cholesterol pool in rats, regardless of the type of fat in the diet of laying hens from which the eggs originated. The content of alinolenic acid in the liver of male rats in group P was 4-6 times higher compared to males in the other groups. Liver lipids and their fatty-acid composition differ by both, sex and dietary modified egg yolk composition in rats.

Therefore, the aim of this study was to investigate the biochemical indicators and serum minerals, for monitoring the nutritional status. Until now subject research did not include testing of the effect of biochemical parameters and hormonal status of the blood of sheep on the quality of milk and milk products. Persistence of this connection is justified by the fact that most of the ingredients of milk just derived from the blood. The main objective of this research was to explore metabolic parameters of sheep's blood, and their relative importance on the quality and quantity of milk components. The study included a total of 127 sheep blood samples from two different areas (Livno and Travnik) in summer feeding period (July, August and September). The animals were marked with the appropriate number of ear tags on the basis of which we always took samples from the same animals through different periods. In sheep blood serum, the concentration of biochemical parameters (glucose, cholesterol, triglycerides, total protein, albumin, urea, AST, ALT, AP, GGT, LDH, calcium, phosphorus and magnesium) and metabolic hormones (triiodothyronine, thyroxine, and insulin cortisol), and samples of milk: milk parameters (milk fat, lactose and protein) as well as fatty acid composition of the milk.

The cows were in their third or fourth parity, had a moderate level of milk production in their previous lactation, and did not have a history of milk fever. The anionic diet significantly improved plasma calcium status, as compared to the control (2.18 vs. 1.99 mmol L–1) and nonsignificantly reduced the incidence of subclinical hypocalcemia (1/12 vs. 5/12) without affecting other periparturient diseases. Other plasma mineral levels were unaffected, except chloride, which was higher in the anionic group. The results show that an anionic diet could improve calcium status around the time of parturition and reduce the incidence of subclinical hypocalcemia when fed to moderate producing dairy cows not predisposed to milk fever.

Beside basic feeds, animals require dietary mineral supplements in order to maintain good health and production, especially if kept in confinement permanently. Adequate mineral uptake together with food and water intake represents one of the basic requirements for successful animal production. Animal feeding practice uses numerous mineral supplements to provide calcium. Limestone (calcium carbonate) is the most widely used out of them all.

The differences between copper toxicity and copper requirement are very small. Although copper is found in adequate amounts over most regions worldwide some deficient areas have been reported in scientific literature. In order to examine the copper status in sheep, during summer of 2003 it were collected samples of soil, plant and blood of sheep at Nišići plateau in Central Bosnia. The results indicated low copper content in pasture (0.56 ppm and 0.72 ppm in May and July, respectively). Low level of copper in blood of sheep (0.39 ppm) confirms this deficiency. Although the soil contained 18.85 and 20.01 ppm of Cu in May and June, respectively, due to interaction with other elements such as Fe, Mo and S it is impossible to give general opinion on the Cu status without studying them.

Milk samples (n=139) were taken from five regions during the spring, summer and winter season. Iodine concentrations were determined by the inductively coupled plasma mass spectrometry (ICP-MS) method. The mean ( standard deviation) milk iodine concentration was 60.9 +/- 67.5 mu g/kg and ranged from 4.4 to 378.7 mu g/kg. Winter milk had higher iodine content (84.0 +/- 88.2 mu g/kg) than the spring (45.3 +/- 46.7 mu g/kg) and summer milk (51.3 +/- 51.0 mu g/kg), although two of five investigated regions did not follow this tendency and had the similar milk iodine content in all three seasons. Very low iodine concentrations (<20 mu g/kg) were found in 41 milk samples from four regions indicating extensive iodine deficiency in dairy cows. Milk samples from...

Alibegović-Zečić Fahira, Crnkić Ć.
Research in the field of horse nutrition, in contrast to the other farm animal species, reached little advancement until the late fifties of previous century. Since that time, popularity of horse keeping increased and significant amount of equine nutrition research was conducted with great advancement in this area. Today is possible to modify horse diet much more precisely than before with minimal risk of consequences following nutrient imbalances. In balancing rations for horses general feeding practice must be followed by exact calculation of nutrient requirements for each class of horse. Only well balanced diet can provide a sufficient intake of nutrients for maintenance requirements, growth, reproduction and work. Balancing diet should be taken individually concerning body weight, physiological state, expected daily feed consumption and intensity of exercise for each horse, as well as climatic conditions and other factors that can affect nutrient requirements. Because unique digestive tract functions and horse feeding behaviour it is important to pay attention on selection of feeds, feeding regimen and water requirements. Balancing diet first requires appropriate feed composition tables and nutrient requirements tables for each horse class. Table data enable us to prepare daily ration to satisfy horse needs in all nutrients and energy. However, well balanced diet also must have positive effects on digestive functions, fertility, as well as health and animal welfare in general. This is reason why the other factors need to considered in diet formulation including forage to concentrate ratio, amounts and sequence of feeding individual feeds, physical form of feeds, number and amount of daily meals, timing of feeding etc. All changes in diet should be conducted gradually over a seven to 10 day period. Diet is to be economic particularly in keeping group of horses or in seasonal variations of feed price.
