Abstract This study evaluated the effect of an injectable multi-mineral complex supplementation on grazing beef cows on subsequent offspring birth weight (BW) and adjusted weaning weight (AWW). Experiment 1 included 1,128 Angus crossbred multiparous suckled cows, from 9 locations in Virginia, that were randomly assigned to one of two treatments: 1) One dose of an injectable trace mineral (6 mL; Multimin® 90, Multimin USA, Ft. Collins, CO) at 71.4±16.8 d of lactation (n = 560); or 2) a negative control with no trace mineral injection (n = 568). In experiment 2, 986 Angus crossbred multiparous suckled cows, at 7 locations in Virginia, were randomly assigned to one of two treatments: 1) Two doses of an injectable trace mineral (6 mL; Multimin® 90) at 118.3±17 days before calving and at 67.7±17.4 d of lactation (n = 494); or 2) negative control with no trace mineral injection (n = 492). All cows had ad libitum access to forage and water, and received additional mineral supplementation in form of mineral blocks. Calves were weaned at approximately 7 months of age, and 205-day AWW was calculated based on birth day, age of weaning and age of dam. No differences between treatments were detected for BW (33.7±1.01 kg; P = 0.50) and AWW (212.2±5.0 kg; P = 0.25) when only one dose of injectable trace mineral was administered to the dam at early lactation. Similarly, when two doses of injectable trace mineral were administrated BW (35.6±1.1 kg; P = 0.70) and AWW (259.4±6.1 kg; P = 0.83) did not differ between treatments. In conclusion, one or two doses of injectable trace mineral administrated at late gestation and/or during lactation had no effect on offspring BW and AWW.

Abstract The objective of this study was to evaluate the effect of an injectable multi-mineral complex supplementation on beef cows overall mineral status and fertility. This study involved 9 different locations in the state of Virginia and a total of 1,128 Angus crossbred multiparous cows. All cows had ad libitum access to forage and water, and received mineral supplementation in form of mineral blocks. All cows were enrolled in a 7-d CO-Synch + CIDR fixed-time AI (FTAI) protocol, followed by natural service for an approximately 70-d breeding season. At the initiation of the FTAI protocol (d 0) cows were stratified by days post-partum (82 ± 18 d) and randomly assigned to one of two treatments: 1) One dose of an injectable trace mineral containing zinc (60mg/ml), copper (15mg/ml), selenium (5mg/ml) and manganese (10mg/ml) on d 0 (n = 560; 1 ml/90 kg BW of Multimin® 90, Multimin USA, Ft. Collins, CO); or 2) a negative control with no trace mineral injection (n = 568). BCS was recorded at d 0, 61 and 121. Estrus detection was recorded at d 10 using an estrus detection patch. Pregnancy was diagnosed on days 71 and 131 by ultrasonography. Liver biopsies were collected on days 0 and 45 in a subgroup of 140 cows from both treatments and distributed among all locations. No differences between treatments were detected in days post-partum (P = 0.83), BCS (P ≥ 0.42) and estrus detection (P= 0.12), neither in mineral status of copper, manganese, selenium or zinc (P ≥ 0.28). No effect of treatment was detected (P ≥ 0.20) in AI pregnancy rate (57%) or overall pregnancy rate (93%). In conclusion, one dose of injectable trace mineral administrated 10 days before AI did not improve pregnancy rate or overall mineral status in multiparous beef cows enrolled in FTAI.

Abstract Trace mineral (TM) supplementation is critical for optimal performance and health. The objective was to determine the effects of varying levels of TM supplementation on feedlot cattle TM status and antibody concentrations. Angus steers (n = 240; BW = 291 kg ± 27.4) were stratified by arrival BW and source and assigned to 1 of 4 treatments (12 pens/treatment; 5 steers/pen). Treatments included a negative control (CON) in which cattle received no TM supplementation, a requirement treatment (1X) in which cattle received added TM at 2016 Nutrient Requirements of Beef Cattle required levels, a 2 times requirements (2X), and a 4 times requirements (4X) treatment. Selenium was included at 0.1, 0.2, and 0.3 mg/kg for 1X, 2X, and 4X respectively. Treatments were chosen based on reported TM supplementation levels from the 2015 Feedlot Consulting Nutritionist Survey. One steer was chosen at random from each pen to be evaluated for serum and liver TM status and antibody concentrations to respiratory viruses. There was treatment × day interaction for serum Co, and liver Cu and Se (P < 0.0001). Serum Co was greatest for the 4X treatment from d 28 through harvest. Liver Cu was greatest for the 2X and 4X treatments from d 56 through harvest. Liver Se was greatest for 2X and 4X from d 28 through harvest. There was an effect of day on liver Co, Fe, Mn, Mo, and Zn (P < 0.0001) and serum Cu, Mn, Mo, Se, and Zn (P < 0.0019). Concentrations for individual TM had different trends over time, however, all reported values were within normal ranges. Serum Zn was greater at harvest (P = .02). There was an effect of time on Bovine Viral Diarrhea Virus Type 1A, Bovine Herpesvirus Type 1, Bovine Parainfluenza 3 virus antibody titer concentrations (P < 0.0001).

Abstract This study investigated the effect of feed intake during late gestation on piglet birth weight and weaning weight of sows with the low backfat thickness (BF) at gestation 90 d. A total of 397 crossbred Landrance × Large White sows according to feed intakes were randomly allotted to three groups 2.8 kg/d (the energy requirement for sow maintenance), 3.6 kg/d and 4.0 kg/d from day 90 to day 110 of gestation. Sows were weighed and measured BF at 90 d and at 110 d of gestation and at weaning. Piglet performance at parturition and at weaning and wean-to-estrus of sows were recorded. Although sows had a tendency to increase BF at gestation 110 d (P = 0.09) and had more BF gain during late gestation with higher feed intake (P < 0.01), there was no evidence for differences in piglet birth weight, within-litter birth weight variation and weak piglet rate, and the number of total born, born alive and stillborn. During lactation, sows fed with high feed intake in late gestation increased body weight loss (P < 0.01). And no differences were observed in piglet performance at weaning and wean-to-estrus interval of sows. In conclusion, during late gestation, sows fed with feed intake more than energy requirement for maintenance had no effect on piglet birth weight or weaning weight.

Inorganic Iodine

Plasma inorganic iodine concentrations (PII, ng/ml) are increasingly used in preference to plasma thyroxine concentrations (T4) for diagnostic purposes. PII represents current dietary iodine intake and responds rapidly (within a very few days) to increases and decreases in dietary iodine (I) intake by cows (Rogers and Mee, 1966). This study measured changes in PII in response to different I intakes supplied by contrasting methods to beef cows during late pregnancy and early lactation.

Different Levels

The winter feeding of beef cows represents a high, proportion of the costs of calf production. Attempts to minimise cost include the use of beef (♂) x dairy cows (♀) which have the ability to suckle two calves and to mobilise body reserves during periods of underfeeding in early lactation. Khan and Topps (1985) observed that cows in good condition at calving could maintain milk production and raise two good calves when given 110 MJ ME/day in a diet which included a source of undegradable protein. Subsequently a preliminary experiment was carried out with three single suckled and nine double suckled cows to examine the effect of energy level on the performance of cows and calves.Three single suckled cows and nine double suckled cows i.e. six with a natural plus foster calf and three with twin calves produced by embryo transfer were used in this experiment. The levels of energy that were examined were 70 or 90, 80 or 100 and 90 or 110 MJ ME/day for single and double-suckled cows respectively, supplied in diets containing ammonia treated straw, barley and fishmeal. Nine of the cows were placed into trios according to calving date and age, with a trio consisting of a cow with a natural calf, a cow with a natural and foster calf, and a cow with twin calves. Each trio was allocated at random to one of the three levels of energy. Similarly, the remaining three cows with a natural and foster calf were allocated at random to 90, 100 or 110 MJ ME/day. The calves were given good quality hay ad libitum and free access to a concentrate mixture up to a maximum intake of 2 kg/head/day. The concentrate mixture consisted of (g/kg) 800 barley, 150 soyabean meal and 50 molassine meal. The experiment started on the 22nd day of lactation and was of 20 weeks duration for most of the cows.

Ad Libitum

Pregnant and nonpregnant Shorthorns were group-fed either hay or grass silage ad libitum from December until midsummer in 2 successive yr. Stage of gestation at the start of feeding each year averaged 120 days. In the 1st yr the cows were housed and in the 2nd they were confined to outside paved lots. Until the start of calving, the pregnant groups tended to consume less than their nonpregnant counterparts. During the 2 wk before the start of calving this difference in intake between pregnant and nonpregnant cows increased up to 12%. However, it was only for the silage-fed, pregnant cows wintered outside that intake was clearly insufficient for maintenance up to 48 h postcalving. Depsite a rapid increase in postcalving intake, all lactating groups lost weight. Results indicated that pregnancy in beef cattle may reduce intake below that expected from nonpregnant animals and may result in insufficient forage consumption for maintenance. During early lactation, beef cows were unable to consume enough stored forage to meet their full energy requirements.

Abstract The objective of this study was to evaluate the effect of two doses of an injectable multi-mineral complex supplementation on beef cow fertility and overall mineral status. A total of 986 Angus crossbred multiparous cows at 8 locations in Virginia were enrolled in a 7-day CO-Synch+CIDR fixed-time artificial insemination (FTAI) protocol, followed by natural service for an approximately 70 d breeding season. All cows had ad libitum access to water, mineral blocks, and diet composed of hay, grass, sudangrass, sorghum grain and commodity pellets, depending on location. Approximately 30 days before calving (d -120, day of AI is d 0) cows were randomly assigned to one of two treatments: 1) Two doses (6 mL) of Multimin® 90 (Multimin USA, Ft. Collins, CO) at d -120 and d -10 (MIN; n = 494); or 2) a negative control with no trace mineral injection (CTRL; n = 492). Body condition score was recorded on d -10, 60 and 120. Estrus detection was recorded at d 0 using estrus detection patches. Pregnancy was diagnosed on d 60 and 120 by ultrasonography. Liver biopsies were collected on d -10 and 60 in a subgroup of 60 cows equally distributed between treatments and among all locations. No differences between treatments were detected in days post-partum (P = 0.66), BCS (P = 0.24) and estrus expression (P = 0.11). Mineral status of copper, manganese, selenium or zinc was similar between treatments before (P = 0.20) and after treatment (P = 0.17). No effect of treatment was detected in FTAI pregnancy rate (50.8%, P = 0.52) or overall pregnancy rate (89.6%, P = 0.64). Two doses of injectable trace mineral administrated approximately 30 days before calving and 10 days before FTAI did not improve pregnancy rate or overall mineral status in multiparous beef cows in Virginia.

Single Farm Payment

Approximately 75% of ewes are housed in Ireland for some portion of the winter, normally the late gestation period. This coincides with a large increase in dietary requirements, with 80% of lamb birth weight laid down in the final two months of gestation (Robinson, 1990) and also udder development during this period. Traditionally, these nutritional requirements were met by feeding grass silage ad libitum and supplementing with concentrates on a stepped rate with advancing pregnancy. With the introduction of the decoupled single farm payment and an ever-decreasing labour supply, sheep producers are looking for financially attractive, low labour alternatives and a concentrate based diet may be one such alternative. The objectives of this experiment were to compare an all concentrate diet supplemented with different fibre sources with the standard silage based diet supplemented with concentrates on feed intake, ewe performance and lamb growth to weaning.

Completely Randomized Design

Supplementation of concentrate feed during late pregnancy of doe is an approach to improve milk yield and kid performance after kidding. The experiment was conducted to find out appropriate level and duration of supplementation to the pregnant doe. The data of the experiment were analyzed applying Completely Randomized Design (CRD) with factorial arrangements with three replications. First factor used in the experiment was the duration of concentrate feeding (15 days, 30 days, 45 days and 60 days) and second was amount of concentrate supplemented (2.00%, 1.75%, 1.50% and 1.25% of their body weight). Birth weight, weaning weight, milk yield and kid mortality in different groups were recorded. Birth weight and weaning weight were found higher in 60 days supplemented group i.e. 2.3±0.23 kg and 10.94±0.41 kg, respectively. Both birth weight and weaning weight were also found higher with 2 percent concentrate feeding group than others i.e. 2.1±0.23 kg and 9.64±0.42 kg, respectively. Milk yield recorded for fourth week shows that higher milk yields were found in 2 percent concentrate supplemented group with 60 days time period. The result showed that by increasing the level of concentrate during late gestation period of does increased the birth weight, weaning weight of kids and increased milk yield of does. So the higher level of concentrate supplementation is required during 45 to 60 days of late gestation in does. Bang. J. Anim. Sci. 2019. 48 (1): 57-66
