Lipid additives are of particular importance in the diet of high-yielding dairy cows. The aim of this study was to determine the effects of a specially designed energy-protein supplement on dairy cows’ performance and milk composition. The experiment was conducted on 24 Polish Holstein-Friesian cows fed total mixed ration. Two kilograms of energy-protein supplement/cow.day were added to the ration for one group of cows whereas the other was fed solely the total mixed ration. The supplement consisted of whole flax seeds, wheat bran, flaxseed and fish oils, and rapeseed cake and its composition is protected by a patent. Feed intake and daily milk yield were recorded automatically for each cow. Gross milk composition and fatty acid profile of milk were determined. An ANOVA was performed to determine the influence of the supplement on performance traits and milk composition. Energy-protein supplement had a positive impact on dry matter intake and milk yield of cows. It had a little effect on the gross milk composition and somatic cell count. The effect of the additive on fatty acids in milk was beneficial, therefore its use in high-yielding dairy cows nutrition is recommended to improve health-promoting properties of milk.

The aim of this research was to observe the effect of heat stress on milk yield and milk compositions of Holstein Friesian crossbred (HF) dairy cows. To fulfill the objectives, a total of 9 Holstein Friesian crossbred cows were selected for this study. Green grasses (German, Para) were supplied adlibitum and concentrate feeds (mixture of wheat bran, rice polish, mustard oil cake, di-calcium phosphate and salt) were supplied at the rate of 2.0 kg/day/cow. Management practices for all the cows were similar following the BAU Dairy farm practices. Data were collected on milk yield (l/h/d), relative humidity (%) and barn temperature (0C). The obtained temperature humidity index (THI) of July, August, September and October were 84.95, 81.99, 81.40 and 79.57, respectively. The highest THI was found in July which indicated higher heat stress during this month. A significant difference (p<0.05) in milk yield of cows was found among different months of July to October. The highest milk yield (6.10±0.50 l/h/d) was found in October among observed months. The compositions of milk such as total solids (TS), solids-not-fat (SNF), fat, protein, lactose, and ash also differed significantly (p<0.01). The highest values (%) of TS, SNF, fat, protein, lactose and ash content of milk were found in October as 12.63, 8.80, 3.83, 3.69, 4.39 and 0.72, respectively and lowest values (%) were in July as 12.20, 8.50, 3.71, 3.50, 4.30 and 0.69, respectively due to the high THI value. From these results, it is concluded that heat stress has strong effect on milk yield and milk composition of HF cows in Bangladesh. Management strategies are needed to minimize heat stress and attain optimal dairy animal performance.Asian J. Med. Biol. Res. June 2016, 2(2): 190-195

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 &lt; 0.05), whereas the ether extract (EE) intake of the cows receiving the PMUP was higher than that of the control (P &lt; 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 &lt; 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.

As a major health problem facing dairy farmers worldwide with substantial economic, production and welfare consequences, lameness has attracted much attention over the last two to three decades (Boelling, 1999). Lameness as a linear type trait is measured by locomotion scoring as there is a high genetic correlation between lameness and locomotion score. Studies have included locomotion (as a predictor of lameness) and have associated lameness with no effect, an increase and sometimes a decrease in milk production of cows. Several reasons have been given for these differences and the need still arises for estimates of the effect of lameness on milk yield in herds with current dairy management. The objective of this study was to quantify the effect of lameness on the daily milk yield (DMY) of dairy cows.

AbstractThis study observes the effects of manipulating the diet in its physical form and in cereal composition of the concentrate on sorting behaviour, feed intake, composition of milk, and degree of discomfort in dairy cows. In a commercial dairy farm with 360 mid-lactation Holstein cows (averaged 105 days), three treatments of feeding handling were applied sequentially during 120 days, each separated by periods of 30 days of resting: (1) Time of chopping of the total mixed ration (TMR): 15min (N= 180) and 23min (N= 180), (2) Physical form of the concentrate: meal (N= 180) and pellet (N= 180), and (3) Cereal composition in the concentrate: mix of corn, barley and wheat in traditional proportions (3.6:1:1) (N= 120), barley only (N= 120) and corn only (N= 120). Animals feeding TMR chopped for 23min selected less and consumed more ration, and had more milk protein and less discomfort than cows feeding TMR chopped for 15min. The physical form of the concentrate, meal or pellet, did not affect feed sorting, but the meal form resulted in greater feed intake and milk fat percentage. The type of cereal in the concentrate did not affect feed sorting but affected feed intake, milk yield and milk composition. In conclusion, it is recommended using TMR chopped during 23min instead of 15min and using the traditional mix of cereals in the concentrate (corn, barn and wheat) instead of using only one cereal.

Effect Of Feeding

Abstract The aim of the study was to compare the effect of feeding a hybrid rye grain in rations for dairy cows during the first 100 days of lactation on body condition, milk yield and milk composition. Feeding cows with concentrates containing in its composition 25% or 40% of the ground hybrid rye did not decrease the intake of concentrate or PMR rations as compared to the control group. The introduction of 25% or 40% of the rye hybrid variety Visello to the concentrates did not reduce the milk yield of the cows during the first 100 days of lactation. No significant differences in the chemical composition of the milk were observed. The cows fed rye maintained their weight and body condition during the first 100 days of lactation at the same level. The addition of hybrid rye grains in the amount of 25% to concentrate had no significant effect on the fatty acid profile of the milk whereas 40% of rye improved fatty acids composition by decreasing C18:0 and increasing C18:1 n-9 in the milk.

AbstractThe objective was to determine the effects of avoparcin, bovine somatotropin (bST) and the additive effects of both avoparcin and bST on milk yield, milk composition, live-weight changes and reproduction parameters in post-partum dairy cows. Forty-eight autumn calving cows were allocated using a split-plot within randomized complete-block design to the following treatments: (i) control (2 ml saline plus 1 kg untreated concentrate per day); (ii) avoparcin (2 ml saline plus 1 kg concentrate containing 100 mg avoparin per day); (Hi) bST (25 mg bST in 2 ml saline plus 1 kg untreated concentrate per day); and (iv) avoparcin plus bST (25 mg bST in 2 ml saline plus 1 kg concentrate containing 100 mg avoparcin per day). All injections were given subcutaneously and treatment continued for 84 days beginning 55 (s.e. 4) days after calving. The cows were offered grass silage ad libitum supplemented with 7·2 kg cereal-based concentrates daily. Milk yield and milk composition were measured thrice and once weekly, respectively. The cows were weighed and body condition score was assessed every 2 weeks.Mean daily milk yield of cows assigned to control was 20·1 (s.e. 1·5) kg, avoparcin, 21·5 (s.e. 1·5) kg, bST, 23·9 (s.e. 1·0) kg and avoparcin plus bST, 25·2 (s.e. 1·2) kg over the 84 days of the trial. bST increased milk yield proportionately by 0·18 compared with all cows not given bST (P < 0·01). Avoparcin did not significantly increase milk yield. There was no effect of any treatment on milk composition, body weight or body condition score. None of the experimental treatments had any effect on calving to first service interval, calving to conception interval, number of services per conception or overall conception rate.These results show that in early lactation, avoparcin alone had no effect on production or reproduction parameters in dairy cows; bST alone increased milk yield but did not affect any other production or reproduction parameter. There was no significant additional increase in milk yield when avoparcin and bST were given in combination, compared with bST alone.

Locomotor activity and daily milk yield of dairy cows during the perioestrous period in successive lactationsThe experiment was conducted in a herd of high-producing Holstein-Friesian cows, using the AfiFarm Herd Management Software, to analyze their locomotor activity during 236 oestruses in relation to the daily milk yield determined during the periooestrous period in four successive production and reproductive cycles. Day "0" was the day of the observed oestrus. Locomotor activity and milk production levels were monitored five days before and five days after oestrus. A correlation was noted between high milk yield and the reproductive performance of cows. An increase in milk yield was accompanied by extended inter-pregnancy and inter-calving intervals and a drop in the insemination index which also tended to decrease in multiparous cows. Primiparous and the highest-yielding cows were characterized by the highest levels of locomotor activity. The physical activity of cows increased by around 67% during oestrus. However, daily milk yield declined at oestrus, compared with the average milk production levels determined five days before and five days after oestrus in each lactation. The installation of pedometers supported the detection of oestrus, including silent oestrus, in dairy cows, and the AfiFarm system was found to be an effective tool for dairy farming and herd management.

Time Of Feeding

Twelve multiparous and ten primiparous cows in late lactation were used in a 16-wk study to determine the influence of feeding times of a protein supplement (PS) on dry matter (DM) intake, ruminal fermentation, milk yield and milk composition. One mixed ration consisting of 50% whole crop oat silage, 10% alfalfa silage and 40% grain concentrate was offered twice daily with two-thirds at 08:00 h and the remainder at 18:00 h. In addition, a PS was offered in one meal per day at either 08:30 h or 00:30 h at an amount equal to 12% of the mixed ration DM intake. Half of the cows were assigned to each of the two dietary treatments which were designated as DAY (08:30 h) or NIGHT (00:30 h). Eight cows in the production study, previously fitted with large-diameter rumen cannula, were used to study treatment effects on rumen fermentation and ruminal in situ nutrient disappearance. Rate of passage of PS was measured using chromium-mordanted PS. Time of feeding PS had no effect on DM intake or body weight. Milk yield and milk composition were not influenced by treatment. Treatment had no effect on in situ DM and crude protein disappearance or ruminal rate of passage of PS. Concentrations of all VFA were not influenced by treatments. All measured volatile fatty acid concentrations were higher during the period of 01:00–06:00 h for cows fed the PS at night. Results indicate that timing of feeding a PS can alter ruminal fermentation characteristic without influencing animal performance.
