“…Goetsch et al (2003) reported that restricted intake of concentrate (approximately 2% LW) and ad libutum intake of roughage can yield average daily gain and average daily gain:dry matter intake similar to ad libutum consumption of a mixed diet. Also, in agreement with the findings in goats, Yrjänen et al (2003) reported that there was no difference in milk yield, milk composition of Finnish Ayrshire cows fed TMR or separate feeding.…”

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).

“…No beneficial effects on rumen function determined by TMR feeding if compared to separate feeding of concentrate as frequent meals during the day were already previously observed by Yrjänen et al . (). Our results seem also to corroborate the finding by Fan et al .…”

This study was designed to evaluate the effects of two feeding methods on milk yield, composition and fatty acid (FA) profile obtained from dual-purpose cattle. Twenty-four Aosta Red Pied cows beyond peak of lactation were assigned to two groups and fed hay and concentrates in the proportions 0.69 and 0.31 on a dry matter basis for 10 weeks. Concentrates were offered separately from forages 6 times a day (separate ration, SR) or as a total mixed ration (TMR). The feeding method did not significantly influence dry matter intake (16.8 vs. 16.9 kg/head/day for SR- and TMR-fed cows, respectively), milk yield (17.4 vs. 17.5 kg/head/day), milk fat, protein and lactose contents (36.4 vs. 35.2, 33.5 vs. 32.8, and 47.3 vs. 47.4 g/kg) and yields (607.9 vs. 613.4, 567.4 vs. 572.7 and 805.5 vs. 829.7 g/head/day). The overall milk FA profile was very similar between groups. Milk concentrations of FA used as indirect markers of rumen function (C18:2 t10c12, odd- and branched-chain FA) and the extent of ruminal biohydrogenation were comparable (P > 0.05) between SR- and TMR-fed cows, suggesting that ruminal pH did not vary considerably as a consequence of the feeding strategy applied.

“…Frequent feeding with concentrate or partial TMR use to limit the load of concentrate to rumen are alternatives approaches to minimize negative effects of separate feeding. Some researchers [44,45,46], reported better feed intake and improvements in milk protein and fat contents with frequent feeding, but some others [47,48,49,50], did not observe any differences, and Fan et al [51], revealed that ad libitum roughage and 4 times concentrate supply was better feeding regimes for dairy cows during warm season. However, frequent feeding with concentrate or partial TMR usage did not improve any performance parameters of the dairy cows in the present study.…”

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.
