“…Milk yield did not significantly differ among the groups although it tended to be higher in the Ko group, which could be related to the higher feed intake and, possibly, a better ruminal utilization of diet components (Maltz et al., ). Couvreur et al.…”

The study tested the hypothesis that certain pastoral forages and olive by-products, available in arid areas, may positively influence fatty acid composition and physicochemical properties of goat's milk. Thirty indigenous goats (body weight = 25.2 kg; age = 4.1 years) were allocated to three groups. During 60 days, the goats received ad libitum either dried olive leaves + Stipa tenacissima (group OL), khortane grass hay (group Ko) or oat hay (control diet, group OH). Milk samples were collected and analysed for total solids, fat, protein, lactose and ash content and fatty acid profile. Average milk yield did not statistically differ among groups. Milk total solids from OL group were higher in comparison with Ko and C groups (15.3, 14.7 and 14.5%, respectively; p < 0.05). Fat content was also higher for the OL group as compared to the other groups (5.44 vs. 5.01 and 4.66%, respectively, for Ko and OH). No significant differences were observed for the milk content of lactose, protein and ash. The percentage of saturated fatty acids of total milk fat was higher in OL and Ko groups compared to the C group (p < 0.001); the milk whereof was characterized by the highest percentage of monounsaturated (p < 0.01) and total unsaturated fatty acids. Milk fat of Ko and C groups showed significantly higher proportions of rumenic (CLA cis-9 trans-11) and vaccenic acids (C18:1 trans-11) compared to OL milk. The feeding system based on Stipa tenacissima and dried olive leaves resulted in the milk lowest proportion of trans-fatty acids and the highest proportion of polyunsaturated ω3-fatty acids (p < 0.05).

“…14 The scientific literature on feeding mixed rations to dairy goats and sheep is sparse and the conclusions are mainly based on studies done with total-MR with a high proportion of 45-70 % of concentrates. 1,32 In Switzerland however, rations for sheep and goats are roughage-based and concentrates are normally fed individually. 42 It has not been surveyed systematically what kind of mixed rations are fed to Swiss dairy goats and sheep (components, quality), how these are prepared and how they are offered to the animals (feeding frequency, amount per feeding and day, etc.)…”

12 dairy goat and 12 sheep farms were visited. The feeding facilities, the feeding management and the composition of the rations fed were recorded. To make a comparison between species, the number of animals feeding simultaneously and the number and types of agonistic interactions during feeding were assessed by direct observations. They were conducted for 6 hours after the morning feeding. It was hypothesized that goats and Schlüsselwörter: Fressverhalten, Sozialverhalten; kleine Wiederkäuer, Bauernhof can be decreased by offering more feeding places.

“…These differences affect rumen retentition time of feed particles, rumen pH, and microbial population (Huuskonen et al 2014). Increasing concentrate in the diet or using it separately may reduce rumen pH and digestibility of dietary fibre (Archimede et al 1995).The 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 (Fox et al 1990;Maltz et al 1991;Gordon et al 1995;Monzon-Gil et al 2010).…”

The objective of this study was to compare the effects of two feeding systems (total mixed ration; TMR vs. roughage and concentrate offered separately; SF) on performance and milk composition of German Fawn (n= 16) and Saanen (n= 16) dairy goats. Animals were randomly allocated into 2 sub-groups and fed TMR or SF system. Roughage:concentrate ratio were arranged as 60:40 in TMR groups. Wheat straw (25%) and chopped alfalfa hay (75%) were used as roughage. Roughage was offered at ad libutum while concentrate was given in two equal meals (total 800 g/goat per day) in SF groups. The study was lasted 50 days. Live weights were recorded before morning feeding. Milk yields were recorded weekly. Individual milk samples were collected to determine total solids, fat, protein, casein, lactose, and urea-N. Feeding systems did not affect (P>0.05) milk yield, body weight, total solid, fat, protein, and casein concentrations. Separate access to roughage and concentrate decreased dry matter intake (P<0.01) and tended to decrease urea-N concentration (P= 0.053). Milk yield of German Fawn does was lower than Saanen does (P< 0.01; 1205.4 g/d vs. 1476.8 g/d). When milk composition of two genotypes were compared, protein was higher (P<0.01) in German Fawn does than Saanen does. In conclusion, there was no advantage of mixed diet over separate feeding for dairy goats having moderate milk yield (1200-1500 g/d).
