“…Some by-product feeds can be very variable in nutrient composition, but the chemical and nutritional compositions of commercial BF is fairly constant (Asko Rantanen, personal communication, Altia Ltd, May 7, 2007).

The objective of the present experiment was to study the effects of partial replacement of barley grain with barley fibre (BF) on animal performance, carcass traits and diet digestibility of growing dairy bulls. The feeding experiment comprised 20 Finnish Ayrshire bulls and 12 Holstein-Friesian bulls, and four treatments (8 bulls per treatment). There were four diets with two offered at stage 1 (from the initiation of the study to 450 kg live weight) and four at stage 2 (from 450 kg live weight to slaughter). The control diet (BF0) included grass silage (460 g kg -1 dry matter) and barley grain (540), BF25 diet included grass silage (460), barley grain (405) and BF (135), BF50 diet included grass silage (460), barley grain (270) and BF (270), and BF75 diet included grass silage (460), barley grain (135) and BF (405). At stage 1 there were only two treatments (BF0 and BF50) and at stage 2, all four treatments were included. All bulls were fed total mixed ration ad libitum. The mean initial live weight of the bulls was 261 kg and the mean final live weight 650 kg. At stage 1 there were no significant treatment differences in dry matter, energy or protein intakes or in live weight gain. At stage 2, replacing barley grain with BF led to a linear decrease of daily live weight gain (P < 0.05) and a linearly reduced feed conversion (kg dry matter kg -1 live weight gain) (P < 0.05). The apparent digestibility of the organic matter and neutral detergent fibre decreased linearly with increasing BF supplementation (P < 0.001). The dressing proportion and the carcass fat score decreased linearly (P < 0.05) with partial replacement of barley grain with BF. On carcass conformation, treatment had a significant (P < 0.05) quadratic effect: the BF25 and BF50 diets were classified highest. The results indicate that 50% of barley starch can be replaced with BF without affecting growth, but feed efficiency factors may decrease when barley starch is replaced with BF. At 75% replacement, feed intake was reduced, which resulted in a lower energy intake and reduced level of performance.

“…Some by-product feeds can be very variable in nutrient composition, but the chemical and nutritional compositions of commercial BF and BP are fairly constant (Asko Rantanen, personal communication and unpublished data, Altia Ltd, 7 May 2007). The nutrient composition of the BF used in the present experiment was quite similar to, for example, that reported by Mäntysaari et al (2007). In this study we chose to compare B and BF diets at a similar proportion of barley grain and BF in the diets and not on an isoenergetic basis, because beef producers in Finland typically use a similar proportion when they replace barley with BF.…”

A 2)2 factorial design with 32 dairy bulls was used to study the effects of partial replacement of a starchy concentrate with a fibrous concentrate and replacement of rapeseed meal with barley protein as protein supplement on performance of bulls with ad libitum access to a total mixed ration feeding. The two energy supplements were flattened barley (B) and a mixture (1:1 on dry matter (DM) basis) of flattened barley and barley fibre (BF). These were fed with either rapeseed meal or barley protein so that the crude protein content of rations was 162 g kg (1 DM. Replacing half of the barley grain with barley fibre increased (P B0.01) the average DM intake (9.3 kg d (1 versus 9.9 kg d (1 ), but had no effect on the average live weight gain (1.27 kg d (1 ). There seemed to be only a minor difference between rapeseed meal and barley protein as protein supplements on animal performance.

“…Some papers have described significant milk FA profile differences between cattle breeds [ 35 , 134 , 149 , 150 , 151 ]. The most often studied milked dairy cattle breeds were Holstein (H), Jersey (J), Simmental, Brown Swiss (BS), Ayrshire (A), and Montbéliarde (M) [ 10 , 49 , 69 , 149 , 152 , 153 , 154 , 155 , 156 , 157 , 158 ]. These results have been summarized [ 18 ] as FA profiles for breeds H, J, BS, A and M. For instance, for MUFA, there were mean variation ranges (in g·100 g −1 of FAs) as follows (for the same order of breeds as listed in the previous sentence): 25.0–39.9; 20.9–22.5; 20.9–29.7; 21.5–24.8; and 16.1–22.0.…”

Fatty acids (FAs) of milk fat are considered to be important nutritional components of the diets of a significant portion of the human population and substantially affect human health. With regard to dairy farming, the FA profile is also seen as an important factor in the technological quality of raw milk. In this sense, making targeted modifications to the FA profile has the potential to significantly contribute to the production of dairy products with higher added value. Thus, FAs also have economic importance. Current developments in analytical methods and their increasing efficiency enable the study of FA profiles not only for scientific purposes but also in terms of practical technological applications. It is important to study the sources of variability of FAs in milk, which include population genetics, type of farming, and targeted animal nutrition. It is equally important to study the health and technological impacts of FAs. This review summarizes current knowledge in the field regarding sources of FA variability, including the impact of factors such as: animal nutrition, seasonal feed changes, type of animal farming (conventional and organic), genetic parameters (influence of breed), animal individuality, lactation, and milk yield. Potential practical applications (to improve food technology and consumer health) of FA profile information are also reviewed.
