“…Main differences of these feeding systems are ways of supply of concentrate and level of feeding (restricted or ad libitum). Increasing concentrate in the diet or using separately may reduce rumen pH and digestibility of dietary fiber [9,10]. TMR is a proper feeding system to solve problem with low ruminal pH which is having a negative effect on the microbial growth and milk fat content [11,12,13].…”

The aim of this study was to investigate the effects of different feeding systems on milk production and milk composition of dairy cows. Thirty-two dairy cows having similar lactation number, Days in Milk (DIM), live body weight and milk production was divided into four groups. First group received Total Mixed Ration (TMR) ad libitum, second group received roughage and concentrate limited and separately in two meals, third group fed with partial TMR which included half of the concentrate in roughage part of the diet and remained concentrate was offered in two meals, and the last group was fed with roughage and concentrate separately and roughage was offered limited in two meals and concentrate was offered limited in four meals. The feeding systems affected dry matter intake (P<0.05). Limited feeding groups were fed on roughage and concentrate separately, the roughage intake in these groups was decreased, concentrate ratio was increased in the diet as well especially in the group receiving concentrate in two meals (P<0.05). In TMR group, milk yield was significantly increased due to increase in their feed intake (P<0.05, 2 kg/day higher than others). Milk total solid, fat and urea nitrogen contents were affected by feeding systems. Restricted and separate feeding system groups had lower total solid, fat and urea nitrogen in milk (P<0.05). In conclusion, the results showed that restricted and separate feeding of concentrate and roughage may not be applicable in practice as it decreased feed intake, milk yield and milk fat test.

“…Increasing concentrate in the diet improves the nutritional status of the goat by increasing energy, protein, mineral and vitamin intake and optimises the efficiency of feed utilization for growth, gestation or milk production (Cerillo et al, 1999). However, concentrate supplementation may reduce the digestibility of dietary fibre (Archimede et al, 1995). It is possible to overcome the difficulties in concentrate use for dairy animals by assigning a proper feeding system such as total mixed ration (TMR) and free-choice feeding with feed ingredients (Görgülü et al, 1996;Fedele et al, 2002).…”

The present study was carried out to compare feeding methods in respect to milk yield and milk composition and to assess dietary preferences of lactating suckling Damascus goats receiving feed ingredients as multiple choices under confinement conditions in Northern Cyprus. A total of 36 Damascus goats was allocated to 4 experimental groups with three replicates comprising three goats each for a total period of 7 weeks. The treatment groups were 1. 0.5 kg concentrate and ad libitum lucerne hay, 2. 1.0 kg concentrate and ad libitum lucerne hay, 3. ad libitum total mixed ration (TMR) containing 40% lucerne hay and 60% concentrate, 4. free choice feeding among the main feed ingredients of the concentrate (barley, soyabean meal, wheat bran) and lucerne hay. The results showed that milk yield, concentrate intake, hay intake, total feed intake, crude protein (CP) and metabolizable energy (ME) intakes and liveweight change were affected (P<0.05) by feeding methods. Choice-feeding increased dry matter, energy and protein intake and milk yield but decreased liveweight loss. Feeding methods had no significant (P>0.05) effects on fat, protein or dry matter contents of milk. However, lactose and non-fat-solids content were affected significantly (P<0.05) by feeding methods, as lactose and non-fat-solids content of the groups increased according to their concentrate intakes.It can be concluded that TMR has satisfactory results in respect to lactational performance of suckling goats and that goats can select a diet corresponding to their nutrient requirements when they are given a choice among different feed ingredients. It is also concluded that free-choice feeding may have the potential to improve production performance of Damascus goats in early lactation.

“…Indeed, the chemical composition of the diet can affect the distribution of rumen bacteria species and their efficiency (Archimede et al, 1995); in particular, the number of cellulosolytic bacteria tends to increase with a diet rich in NDF or forage (Weimer et al, 1999). Moreover, Shingfield et al (2005) and Nielsen et al (2004) showed that changes in dietary starch and NDF affect the ratio of odd-chain, iso-and anteiso-FA in milk, as a consequence of changes in rumen microbial strains.…”

Little information is available about the effect of different forage species on the rumen biohydrogenation process. The aim of the present work is to compare the in vitro production of cLA and c18:1 isomers after incubation of three different herbage species in rumen liquor from sheep. Pasture herbage samples of lucerne (Medicago sativa; MS), ryegrass (Lolium multiflorum; LM) and oats (Avena sativa; AS) were submitted to in vitro fermentation with sheep rumen inoculum. Samples were collected at 2, 4, 6 and 8 hours of fermentation.The fatty acid profile of MS was characterised by 11.62 (g/100 g of lipid extract) of linoleic acid (LA) and 27.08 (g/100 g of lipid extract) of α-linolenic acid (LNA), whereas LA in the other two herbages was 6.60 (g/100 g of lipid extract) and 6.95 (g/100 g of lipid extract) in AS and LM, respectively; LNA was 52.20 (g/100 g of lipid extract) and 54.49 (g/100 g of lipid extract) in AS and LM, respectively. The crude fat content of botanical species was respectively 11.90 (g/100g DM) for AS, and 15.77 (g/100g DM) for LM and 26.17 (g/100g DM) for MS. Rumenic acid (RA, cis-9, trans-11 CLA) was the predominant CLA isomer and the maximum yield was attained with AS after 6 hours of fermentation (0.81 g/100 g of lipid extract); RA concentration remained quite low with the other two herbages. The concentration of the other isomer (trans-10, cis-12 CLA) was always very low; the maximum yield (0.09 g/100 g of lipid extract) was reached after 6 hours with AS. The maximum yield of vaccenic acid (VA, trans-11 C18:1) was reached after 8 hours with MS (2.64 g/100 g of lipid extract). This herbage also produced the highest amount of trans-10 C18:1 at 6 and 8 hours (0.17 g/100 g of lipid extract). AS appeared to have induced the highest amounts of RA relative to the other two forages. The differences in conjugated dienes and c18:1 isomers content during fermentation could be due not only to different amounts of LA or LNA in the herbage, but also to different releasing times of FA from the plant substrate.
