AbstractThis research paper addresses the hypotheses (1) that milk produced from hay-fed cows differs from that of silage-fed cows and (2) that silage type has an important impact, too. Four diets differing in forage type but with equal estimated milk production potential and a forage:concentrate ratio of 0.85 : 0.15 were compared regarding their effect on feed intake, milk yield and milk properties. The forages tested were hay, grass silage, conventional short-chopped and long-chopped maize silage subjected to a novel processing technology (Shredlage®). Twenty-four dairy cows were fed two of the four diets in two consecutive runs in an incomplete (4 × 2) Latin-square design (n = 12 per diet). Each experimental period lasted 22 d, with 12 d of adaptation and 10 d of sampling. During sampling, feed intake and milk yield were recorded daily, milk composition and coagulation properties were determined four times. The composition of the diet ingredients was analysed weekly. Data were analysed with a mixed model considering feed, period and their interaction as fixed effects. Stage of lactation, milk yield and milk composition from the pre-experimental period were used as covariates in the model. Dry matter intake was lower with the long-chopped processed maize silage compared to the other three groups. There were some diet differences in intakes of net energy for lactation and absorbable protein in the duodenum, but this did not result in changes in milk yield. The milk fat content was higher with the grassland-based diets compared to the maize silage diets. No treatment effect on milk acidity and rennet coagulation properties was observed. In conclusion, there were no indications for specific physico-chemical properties of milk from a hay-based diet, and maize processing technology was not of large effect either. Future investigations should focus on sensory differentiation of the milk produced with different forages.

Mansbridge (1995) reported that replacing ground wheat with a mix of ground wheat and maize grain increased milk protein concentration, which led the authors to speculate that increased inclusion of maize grain increased rumen by-pass starch. Indeed, de Visseret al(1990) reported that feeding less rapidly degradable starches has led to increased milk protein concentration.The objective of this study was to examine the effects of starch concentration and source on feed intake, milk yield and milk composition of dairy cows.

Context Several agro-industrial by-products such as oil palm meal could be useful as animal feeds in support of low cost of feed for livestock production. Aims This study investigated the effects of oil palm meal and urea pellet (PMUP) as a protein replacement for soybean meal (SBM) on feed intake, nutrient digestibility, rumen fluid characteristics, milk yield and milk composition in lactating dairy cows. Methods Five multiparous, early to mid-lactation, Holstein-Friesian crossbred dairy cows (75% Holstein-Friesian × 25% Thai Native Bos indicus) were randomly allocated in a 5 × 5 Latin square design to receive PMUP replacement for SBM at 0, 25, 50, 75 and 100% in concentrate. Key results The results show that roughage, total dry matter (DM), organic matter (OM) and acid detergent fibre (ADF) intakes in the cows fed with 25–75% PMUP were significantly higher than in the cows fed 100% PMUP (P < 0.05), whereas the ether extract (EE) intake of the cows receiving the PMUP was higher than that of the control (P < 0.05). Accordingly, the apparent digestibility, ruminal ammonia nitrogen (NH3-N) and total volatile fatty acid (VFA) of cows fed with PMUP replacement of SBM at 25–75% was higher than that in cows fed with 100% PMUP. In addition, milk yield and milk composition were not significantly different among treatments, whereas feed costs per kg milk yield was lowest in cow fed with 100% PMUP (P < 0.05). Conclusions Replacing SBM with PMUP up to 50–100% in concentrate could reduce costs of feed per kg milk yield, but lower feed intake, nutrient utilisation and rumen fermentation were observed in cow fed with 100% PMUP. The use of PMUP from 25–75% replacement of SBM had no significant effects on the feed intake, nutrient utilisation, rumen fermentation and milk production. Therefore, the level of PMUP replacement of SBM in concentrate for lactating dairy cow should not exceed 75%. Implications PMUP could be used as a protein replacement for SBM in concentrate for lactating dairy cows. These findings should be applied further in practical farm condition in order to increase livestock production efficiency.

The objective of this study was to research the influence of the sweet sorghum straw fermented by the Compound Microbial Agent on the milk yield and milk composition of the cows. The results indicated that sweet sorghum straw bio-feed fermented by the Compound Microbial Agent in bags could increase the feed intake (11.4%) and milk yield(14.2%) compared with the control group, it also has improved milk protein (14.03%) and butterfat rate (16.3%) ,and has reduced the somatic cell's number(5.15%) compared with the control group. The sweet sorghum straw fermented by the Compound Microbial Agent has reduced the milk-feed ratio (20.8%).It has improved the feed digestibility and utilization and reduced the costing.

Effect Of Feeding

Feeding the dairy cow during the transition phase (dry to lactating) has been found to effect subsequent feed intake and milk yield (Moorby et al., 1996; Olsson et al., 1998). The aim of this study was to compare the effect of feeding a liquid feed during the prepartum period on; feed intake, milk yield, milk composition, live weight loss and blood metabolite levels.
