This study aimed to determine protein and energy metabolites in postpartum Brown Swiss cows and their effect on the presence of subclinical ketosis and reproductive parameters. One hundred cows from four farms in the Mantaro Valley (Junín, Perú) were grouped according to parity (1, 2, 3 and 4). The variables of the metabolic profile (total proteins, blood urea nitrogen [BUN], glucose, βhydroxybutyrate [B-HB]), milk production and body condition were estimated between 7 to 60 days postpartum in 7-day intervals. Likewise, the calving-first heat interval and the pregnancy rate at first service were recorded. The determination of subclinical ketosis was based on a semi-quantitative analysis by levels of B-HB in milk (µmol/l) using a commercial kit. BUN levels ranged between 11.74 and 15.92 mg/dl, being higher in fourth parity cows (p<0.05). The averages of total protein (6.54-7.90 g/dl) were homogeneous between calvings. The glucose values presented an inverse response, being lower in cows of third and fourth parity compared to cows of first and second parity (p<0.05). Similarly, the highest levels of milk production were observed in third parity cows (14.41 ± 5.42 l/d) and fourth parity (15.43 ± 4.36 l/d) with respect to first and second calvers (p<0.05). Body condition was lower in cows with subclinical ketosis. The calving - first heat interval and the pregnancy rate at first service were lower in cows with subclinical ketosis (p<0.05).

SummaryObjective: It was the purpose of this study to determine the effects of non-esterified fatty acids (NEFA) concentrations at different time periods of the transition period as well as lactation number on metabolism, health, reproduction and milk production in dairy cows. Material and methods: This trial was conducted in a single dairy herd located in Northern Germany. Of the herd, which comprised 330 lactating Holstein cows housed in a free stall barn and fed a total mixed ration (TMR), 83 primiparous and multiparous cows were randomly selected. Animals were checked for body condition score (BCS), locomo tion score, calving data, quality of colostrum, reproductive measures, daily rectal temperature of the first 10 days post-partum (p. p.), health data and culling rates up to 200 days in milk (DIM) as well as milk production until 305 DIM. Three different time periods were considered: 3 and 1 week ante partum (a. p.); partus and 1 week p. p.; 3 weeks p. p. Results: Animals with NEFA concentrations 0.4 mmol/l ante partum had a higher risk of no ovarian activity in week 5 p. p. and of subclinical ketosis post partum than cows with lower NEFA concentrations (p < 0.05). Cows with NEFA concentrations 1.1 mmol/l in week 1 p. p., in comparison to those with lower NEFA concentrations, showed a higher prevalence of clinical ketosis (24.1% vs. 5.9%), subclinical ketosis (62.1% vs. 34.0%) and culling rate within 200 DIM (34.5% vs. 14.0%) (p < 0.05). Cows with NEFA concentrations 0.3 mmol/l at week 3 p. p. had higher 100- and 305-day milk yields than cows with lower NEFA concentrations (p < 0.05). First lactating heifers were at higher risk to loose body condition ante partum, of dystocia, fever within the first 10 DIM, metritis, clinical and subclinical ketosis as well as to develop a disease within the first 30 DIM (p < 0.05). Multipara were more likely to loose body condition after calving, to a prolonged calving to first service interval and to higher milk yields (p < 0.05). Conclusion: In conclusion increased NEFA concentrations during the transition period as well as parity can have an influence on health, production and reproduction of dairy cows.

Abstract A total of 300 dairy cows were randomly enrolled from 11 dairy farms in Turkey. The beta-hydroxybutyric acid concentration (BAC) was tested in the blood (BBAC) and individual milk (MBAC) samples at postpartum week 2 (PPW2) and week 4 (PPW4) for the detection of subclinical ketosis (SCK) in Holstein, Montbeliard, Simmental and Holstein-Crossbred (HC; only BBAC). The prevalence of BSCK (BBAC ≥ 1.2 mmol/L), MSCK1 (MBAC = 100 µmol/L), MSCK2 (MBAC ≥ 200 µmol/L) and MSCK1/2 (≥ 100 µmol/L) was 8.3, 11.8, 5.8 and 17.3% at PPW2 and 4.7, 4.9, 6.9 and 11.9% at PPW4 in Holstein respectively. SCK was not observed in Simmental and HC. The prevalence of BSCK and MSCK1 at PPW2 were 4.3 and 43.5% in Montbeliard respectively. Primiparous Montbeliard and Holstein had significantly higher MBAC at PPW2 than PPW4. Overall, HC and Montbeliard had significantly lower BBAC. Cows having body condition scores 2 and 4 at calving had higher MBAC at PPW2 and 4 that was associated significantly with metritis and multiple diseases. Holstein with BCS4 at calving had higher BBAC at PPW2 and 4. Holstein with SCK was more likely to develop postpartum metabolic health disorders (PPHD) in 90 days in milk (90DIM). MSCK1 did not associate milk production loss in Montbeliard and Holstein. Holstein with both BSCK and MSCK2 at PPW2 had a 6.7 kg average daily milk yield loss in 90DIM. Conclusively, SCK was not observed in Simmental and HC, and MSCK1 didn’t cause PPHD and milk yield loss in Montbeliard. BSCK and MSCK2 created a significant risk for PPHD and milk production loss in Holstein.

Mastitis is a complex disease causing inflammation of the udder, which has been estimated to cost the dairy farmer between £40-£117/cow per year (Stott et al., 2002). Economic loss occurs as a result of discarded milk, reduced milk yield and milk quality, increased vet costs and an increase in replacement costs. The objective of this study was to examine the effect of breed on the incidence of mastitis and somatic cell counts and milk production capabilities of Holstein Friesian, Brown Swiss and Brown Swiss crossbred cows.

Abstract Improvements in modern sow prolificacy have markedly increased the number of pigs weaned, thus the ability of sows to provide nutrients to support fetal growth and milk production has been enhanced. The goals of the gestation nutrition program consist of meeting the nutrient requirements for maintenance and growth and for adequate conceptus development, while managing body condition. Early gestation represents the best opportunity for replenishing body reserves, whereas in late gestation, both estimated protein deposition and energy requirement are exponentially increased and directed towards fetal growth and mammary development. Increased feed intake after breeding has been presumed to be detrimental to embryo survival; however, data with modern line sows demonstrates to feed thin sows to recover body condition as quickly as possible while avoiding feed deprivation immediately after breeding. Importance of body condition scoring remains unchanged: feed thin sows to bring back to adequate body condition and prevent over-conditioned sows at farrowing. A recent meta-analysis showed increasing late gestation feed intake seems to modestly improve piglet birth weight by 28 g per piglet in gilts and sows. Also, recent findings in gestating sows suggest modern genotypes have improved feed efficiency and propensity for growth. Therefore, increasing energy intake during late gestation has a modest effect on piglet birth weight and a negative effect on stillborn rate. Historically, lactation catabolism impacted subsequent reproductive performance of sows, particularly in first-parity. However, contemporary sows appear to be increasingly resistant to the negative effects of lactational catabolism. Even so, continued emphasis on maximizing lactation feed intake is critical to support milk production and prevent excessive lean tissue mobilization. Research data suggests that ad libitum feeding and offering lactation diets during the wean-to-estrus interval is not needed. Modern genetic sow lines appear to be more robust from a nutritional perspective than in the past.

Two experiments were carried out to measure effects of body condition at calving and different levels of feeding after calving on milk and subsequent reproduction.In experiment 1, which was conducted in two consecutive years, 162 cows (77 in year 1 and 85 in year 2) were group feed so as to reach a target body condition (condition scores ranging from 3-6) four weeks before calving. During the last four weeks before calving, all cows were managed so as to maintain their individual condition scores. At calving, cows in similar condition of similar breed and with similar previous milk production were allocated to high and low levels of feeding at pasture for the first five weeks of lactation. Mean pasture intakes were 13.0 and 7.0kg dry matter (DM)/cow.d in year 1 and 15.0 and 8.5 kg DM/cow.d in year 2In experiment 2, 40 cows were offered pasture and hay from 20 weeks before calving to achieve a body condition score of either 4 or 6 by two weeks before calving. During the first five weeks of lactation, cows were individually fed in stalls on freshly cut pasture at one of three levels of intake, 7 or 10 kg DM/cow.d or .In both experiments cows were grazed as one group from week 6 to 20 of lactation.Improved body condition at calving resulted in an extra 4.0, 11.0 and 7.4 kg milk fat per unit condition score over 20 weeks of lactation, for year 1 and 2 of experiment 1, and experiment 2, respectively. Cows in poorer condition partitioned a higher proportion of feed energy to liveweight at the expense of milk production than did the cows in better condition. However, increasing the plane of nutrition in early lactation resulted in higher levels of milk production and reduced the need for cows to mobilize bodyreserves. Improved body condition at calving had a positive effect on milk fat percentage, particularly in early lactation, but did not affect milk protein percentage. Input-output relations calculated from the experimental data showed that the benefit sf to improve body condition before calving was less than that of additional feeding after calvin changes in the condition of the cows were taken into consideration (25.8 vs 1 4.6 kg DM to yi kilogram of milkfat). Improvements in condition and feeding in early lactation reduced the anoestrus interval after calving by 5.7 d for each additional condition score at calving and 1. d for each additional kgDM/cow.d fed over weeks 1-5 of lactation. The input-output relations resented will enable farmers to assess the likely consequenes of changes in their feeding management in the crucial peripartum period with a greater degree of confidence than in the past.

A milking experiment with range, single-suckled beef cows was conducted over two lactations in 1976 and 1977 at the University of Alberta Research Ranch. A total of 428 cows were milked, ranging from 2 to 10 yr of age and representing four breed groups of Herefords and crossbreds of traditional beef and dairy breeds. Measurements of milk were taken in June and September each year. Milk was extracted following an intrajugular injection of 20 IU of oxytocin. Samples were analyzed for butterfat percent, protein percent and lactose percent. Age and breed of dam differences in milk yields, constituent percentages and yields were assessed. Least squares means of yields pooled over the two periods each year indicated that dams with Holstein and Brown Swiss breeding (DS) yielded more milk than beef crossbreds and purebred Herefords. Average milk yields estimated over 24 h ranged from 5.7 kg/day for Herefords to 7.8 kg/day for DS dams. Compared to 2-yr olds at 100%, 3-yr olds produced 125%, 4-yr olds 136% and mature cows 139% greater yield. The difference between June and September yields was evident between breed groups. Hereford milk production exhibited the greatest decline over 87 days compared to all other crossbreds and DS were the most persistent. Mature cows maintained milk yields better than younger cows, and 2-yr old milk yields declined most noticeably. All crossbred groups produced less butterfat percent and lactose percent content than the Herefords, yet yielded more total energy. All constituent percentages were higher than those reported for commercial dairy cattle. All constituent percentages increased significantly from June to September at approximately 130 days in lactation. A significant decline was noted for all constituent yields in September. Dairy crossbreds demonstrated the highest persistency for all constituent yields. Beef Synthetic dams were intermediate in yield persistency. Average milk yields had negative (P < 0.05) correlations with average constituent percentages. Inter-correlations among constituent percentages were variable and generally small and negative.
