Performance and Metabolism of Dairy Cows Fed Bean Seeds (Vicia faba) with Different Levels of Anti-Nutritional Substances

The aim of this study was to determine the effect of selected bean cultivars with different levels of anti-nutritional substances on performance and metabolism of dairy cows. In the current twelve-week-long study, 32 dairy cows at 3 to 6 weeks after parturition were divided into four groups. Diets were balanced to have an analogical content of crude protein and energy. Experimental groups (MI, ME, MET) were mixed to the milking concentrate consisting of 20% bean seeds (MI - MISTRAL cultivar with a low content of anti-nutritional substances; ME - MERKUR cultivar with high content of anti-nutritional substances; MET - MERKUR cultivar with technologically reduced the amount of anti-nutritional substances). Clinical evaluation of dairy cows’ health and feed intake showed no negative effect of the bean supplementations. Energy, nitrogen and mineral metabolisms were not impaired either. No significant differences were found between groups in milk performance (daily milk yield, protein and lactose production) during the study. On the basis of these results, the bean can be used in 20% in the milking concentrate of dairy cattle. Health risks associated with anti-nutritional content of the native bean are not significant for high-producing dairy cattle.

Impact of genotypes and parity on some vital reproductive and productive attributes in the local (L×L, n = 100) and four crossbred cows (L×F, L×SL, L×JR and L×S; n = 318) raised in randomly selected smallholder dairy farms scattered all over Natore District and adjacent areas have been assessed during a period from September 2007 to June 2010. With regard to reproductive attributes, significant differences existed among the cattle genotypes (P<0.05) except for gestation length (GL) and age at weaning (AW). The lowest age at puberty (AP) was found for L×F (21.42±0.37 months), while the highest for L×L (31.67±0.74 months). In terms of productivity, L×F cows produced the highest daily milk yield (DMY; 6.22±0.13 L), coupled with the highest total lactation yield (TLY; 2163.43±47.77 L), while L×L produced the lowest values (1.49±0.04 L and 416.40±12.3 L, respectively) for the traits. The effect of parity on both reproductive and productive attributes showed that the middle-aged dairy cows of the 3rd and 4th parities performed better than the younger (1st and 2nd parities) or the older (5th and beyond) ones. Considering the overall performance, the L×F cows could be ranked as the best genotype followed by their L×SL, L×JR, L×S and L×L counterparts in the study area.

Aiming determination of the variability of production traits (daily milk yield and composition) and microclimate parameters (ambient temperature and humidity) in the barns; as well as the correlation between the analyzed groups of traits, 1,636,192 test-day records from Simmentals and 1,275,713 test-day records from Holsteins were analysed. Performed analysis indicate high variability of production traits due to cow?s breed, parity as well as breeding region. Also, high variability of microclimate parameters in the barns due to season and breeding region was found. Furthermore, statistically highly significant (p < 0.001) correlations between the production traits and microclimate parameters were determined. Finally, the negative effect of inadequate microclimate on daily milk production was determined in both breeds in all breeding regions. Since genetic evaluation and selection of dairy cattle for heat resistance is only long-term method for heat stress managing, determined effect will be taken into account in the statistical model for estimation of genetic parameters and breeding values.

Sixteen Holstein and Brown Swiss cows, 112 ± 45 days in milk, were assigned by stage of lactation to a replicated 4 x 4 latin square experimental design with three-week periods. Treatments A, B, C and D were based on pelleted concentrates (CT), theoretically equal in contents of nitrogen (18.0 to 18.3% crude protection) and energy (2.6 Meal NEL/kg) and containing, respectively, 0, 2, 4 and 8% of SynerMax®3 (coproduct of antibiotic production). These were fed at a rate of 1 kg CT/2 kg milk (recalculated weekly) in three daily meals, along with limited access to long hay and nighttime grazing at four cows per hectare on unfertilized grass swards. Mean results for A through D were, respectively: daily CT intake, 10.64, 10.84, 10.25 and 10.57 kg; daily milk yield, 21.32, 21.91, 21.63 and 20.97 kg; milk fat content, 2.76, 2.75, 2.52 and 2.76%; protein content, 3.06, 3.02, 3.02 and 3.04%; ratio of milk to CT (M/CT), 2.01, 2.02, 2.11 and 1.98. Significantly different were the higher CT intake with 2% SynerMax® (B) vs. 4% and 8% (C + D) (0.43 kg difference, P < 0.05), and the higher M/CT with 4% than with 8% SynerMax® (C vs. D) (0.13 kg difference, P < 0.01). Incorporation of SynerMax at levels of 2 and 4% in pelleted CT assured good animal acceptance and had no adverse effects on lactational performance.

Automatic milking system (AMS) brings a change in approach to ensure the data reliability in the official milk recording (MR). The AMS is equipped with flowmeter. AMS software provides the daily milk yield (DMY) and average of the last 7 daily milk yields (AVG7) for MR. Classic MR uses DMY. AVG7 could be more reliable value. Origin of both records (DMY and AVG7) is from AMS flowmeter. The aim of paper was to compare the values of milk yield of cows from daily (DMY) and the extended records (AVG7) from AMS for objective assess of lactations to be used in cattle breeding. Study (2013) with 2 AMS herds (DeLaval and Lely Astronaut): herd 1 – Holstein (H) dairy cows; herd 2 – Czech Fleckvieh (CF) dairy cows. There were following milk records: n = 521 DeLaval (H); n = 567 Lely Astronaut (CF); 70 (H) and 68 (CF) dairy cows. MR samples were analyzed on: fat content; crude protein; somatic cell count. Correlations between AVG7 and DMY were: 0.888 (H); 0.898 (CF, both P ≤ 0.001). There were insignificant differences (P > 0.05; −0.07 ± 3.29 kg for H and 0.28 ± 3.3 kg for CF) between AVG7 and DMY for both robots. The same is valid for differences in the production of milk components. According to this comparison experiment the AVG7 of AMS is a suitable equivalent for the DMY regarding official MR for assessment of lactations.

Abstract. The aim of this study is to determine the effect produced by selected pea cultivars with different anti-nutritional content on dairy cows’ metabolism. In the current ninety-day present, 32 dairy cows were divided into four groups (Z, G, GU and C). Three experimental groups (Z, G and GU) were fed a production mixture consisting of 25% pea seeds and the following: (Z – Zekon cultivar with low anti-nutritional content; G - Gotik cultivar with high antinutritional content; and GU – Gotik cultivar whose anti-nutritional content was reduced technologically). The control group was fed the production mixture with a higher proportion of extracted soybean meal and grain meal. Feeding rations were balanced to have an analogical composition of crude protein and energy. Feeding the pea supplement did not affect energy metabolism of the dairy cows. As for nitrogen metabolism, group Z showed higher concentrations of ammonia in rumen fluid and urea in blood compared to groups GU and C. No animal from the experimental groups showed reduced intake of feed. An insignificantly lower performance was noted (daily milk yield, protein production and lactose production) in group G. Overall, better results were observed in group Z. On the basis of the current study, peas can be used as an alternative source of proteins and energy in the diet of dairy cattle.

Context In Brazil, dairy cattle pasture-based systems use grass pasture as the main feed source, with little or no supplementation. However, it is necessary to invest in nutritional technologies that allow dairy cattle systems to produce milk with a high protein and energy content, and better total bacterial counts at low costs. Aims This study aimed to evaluate the effect of adding a common bean residue (CBR) to cattle diets on feed intake, digestibility and feeding behaviour of lactating dairy cows. Methods Eight lactating Holstein × Zebu crossbred cows, with an average bodyweight of 500 ± 30 kg (mean ± s.d.) and a mean daily milk yield of 13 ± 2 kg/cow were randomly assigned in a double 4 × 4 Latin square. The treatments consisted of four increasing levels of CBR (134, 240, 348 and 449 g/kg) in the concentrate. Key results The inclusion of CBR linearly decreased (P ≤ 0.034) the DM intake and neutral detergent fibre intake of pasture, sugarcane and the total diet. The inclusion of CBR did not affect (P ≥ 0.111) grazing, rumination or idle time. The feeding efficiency in kg DM/h and kg neutral detergent fibre corrected for ash and protein/h linearly decreased (P < 0.001), with an estimated decrease of 39.1 and 23.4 g/h respectively for every 10 g/kg of CBR added to the concentrate. The number of boluses per day and the time spent per ruminated bolus were not affected (P ≥ 0.086) by CBR inclusion. Conclusions The results obtained in this study indicate that the inclusion of up to 240 g/kg of CBR to the diets of lactating dairy cows with a mean daily milk yield of 13 kg, managed on pastures, is recommended. Implications The use of CBR, which has high availability in several countries, may be an alternative to supplying small ruminants.

In order to determine the persistence of heat stress effect in dairy cows regarding the breed, parity and susceptibility to heat stress, over 1.9 million of test-day records from Holstein and Simmental cows reared in Croatia were used. The persistence of heat stress effect in the subsequent milk recordings was determined in cows that had significant decrease of daily milk yield at different THI threshold value (65, 70, 75, 80, and 85). The obtained results indicate that cows heat stressed at lower THI threshold value had higher proportional drop of daily milk yield in subsequent milk recordings. Also, primiparous and Simmentals experienced higher proportional drop when compared to multiparous and Holsteins. The negative effect of heat stress on daily milk contents that existed in all cows was more pronounced in the 2nd subsequent milk recording. The determined increase of somatic cell count in more heat stress sensitive Holsteins (THI in 65, 70, 75) indicates that Holstein cows, in terms of heat stress, also become more susceptible to mastitis. Finally, the lower was the THI threshold value, the stronger and more persistent was the heat stress effect. Considering the quite probable increase of the frequency of heat stress days, it is necessary to develop an adequate strategy for dairy farming. Aiming the accurate answer to the problem of heat stress in this region, it is necessary to conduct further research on genetic evaluation.
