ABSTRACT Objective. Determine the effect of Glycoline® on reproductive efficiency in high producing dairy cows. Materials and methods. 100 Holstein cows one month before delivery were selected. About 21 days before parturition they were put in a barn and were randomized in two groups: Glycoline® Group (GG, n=50), 300 g/day of Glycoline® for 21 days antepartum and 250 g/day of GlycoLine® over the following 21 days postpartum, and the Control Group (CG, n=50) with the same feed and silage ration as GG during the same period, but without the addition of Glycoline®. Events and reproductive variables of the cows were recorded for 202 days. The data were systematized, analyzed and statistically compared. Results. Comparisons were made between GG and CG respectively: Retained placenta (0.0 vs. 12.0%; p=0.027), downer cow syndrome (14.3 vs. 44.0%; p=0.002), uterine involution (64.6 vs. 36.4%; p=0.019 ), uterine infection (10.4% vs. 35.5%; p=0.006), no ovarian activity (6.3 vs. 25.6%; p=0.018), follicular cysts (0.0 vs. 18.2%, p = 0.002), luteal structures (25.0 vs. 9.3% ; p=0.058), mean estrus presentation (40.1% vs. 63.5%; p=0.033) inseminated females (79.6 vs. 68.0%; p=0.017), pregnancy rate at day 150 (57.1 vs. 46.0%; p≥0.317 ) and intervals (days): calving to 1st estrus (39.8 vs. 63.2; p≤0.006), calving to IA (62.4 vs. 87.5; p≤0.006) calving to conception (81.7 vs. 93.6; p≤0.006; p=0.103). Conclusions. Results suggest that dietary Glycoline® added in the transition period improves reproductive efficiency of high-producing dairy cows. RESUMEN Objetivos. Determinar el efecto del Glycoline® sobre la eficiencia reproductiva en vacas lecheras de alta producción. Materiales y Métodos. Se seleccionaron 100 vacas Holstein un mes antes del parto. Alrededor de 21 días antes del parto se ubicaron en un establo y se asignaron al azar a dos Grupos: Grupo Glycoline® (GG; n=50), 300 g/día de Glycoline® durante 21 días preparto y 250 g/día de Glycoline® durante los siguientes 21 días posparto y Grupo Control (GC, n=50) la misma ración de concentrado y ensilaje que el GG durante el mismo período de tiempo, pero sin la adición de Glycoline®. Se registraron los eventos y las variables reproductivas de las vacas durante 202 días. Los datos fueron sistematizados, analizados y comparados estadísticamente. Resultados. Comparaciones entre el GG y GC respectivamente: Retención de placenta (0,0 vs 12.0%; p=0.027), síndrome de vaca caída (14.3 vs 44.0%; p=0.002), involución uterina (64.6 vs 36.4%; p=0.019), infección uterina (10.4% vs 35.5%; p=0.006), sin actividad ovárica (6.3 vs 25.6%; p=0.018), quistes foliculares (0.0 vs 18.2%, p=0.002), estructuras luteales (25.0 vs 9.3%; p=0.058), promedio presentación de celo (40.1% vs 63.5%; p=0.033), hembras inseminadas (79.6 vs 68.0%; p=0.017), tasa de preñez al día 150 (57.1 vs 46.0%; p≥0.317) y intervalos de tiempo (días): parto 1er -celo (39.8 vs 63.2; p≤0.006), parto-IA (62.4 vs 87.5; p≤0.006) y parto-preñez (81.7 vs 93.6; p≤0.006; p=0.103). Conclusiones. Los resultados sugieren que el Glycoline® adicionado en la dieta en el período de transición, mejora la eficiencia reproductiva de vacas de alta producción.

Postpartum Estrus

This study was undertaken on 36 freshly calved cows randomly divided into 6 equal groups under field conditions. Cows of group-VI that shed placenta within 8-12 hours postpartum naturally served as healthy control. The cows with retained fetal membranes (RFM, n = 18) for more than 12 hrs were managed either by manual removal of placenta without antibiotics (group-I), parenteral antibiotic (Ceftiofur 1 g i/m) for three consecutive days (group-II) or a combination of both (group-III). In group-IV and group-V, cows were administered with Inj. Oxytocin @ 50 IU i/m and Inj. Dinoprost tromethamine (PGF2α) @ 25 mg i/m, respectively, immediately after parturition and time of placental shedding was recorded. The overall prevalence of Brucellosis by RBPT was found to be 5.55 % amongst these 36 animals. The placental expulsion in groups following medicinal treatment was found to be 50 (3/6) % in Ceftiofur alone by 3 days (group-II), and 66.67 (4/6) % in Oxytocin (group-IV) and 100 (6/6) % in PGF2α inj. (group-V) groups within 12 hrs. The time of uterine involution in groups I to VI was found to be 42.00 ± 1.94, 39.50 ± 0.99, 40.67 ± 1.39, 38.33 ± 1.55, 37.50 ± 1.02 and 37.33 ± 1.76 days, respectively, while the interval for the appearance of first postpartum estrus was 54.83 ± 2.06, 51.00 ± 1.05, 52.17 ± 1.96, 50.17 ± 2.03, 48.67 ± 1.90 and 49.17 ± 1.55 days, respectively, which did not vary statistically. The mean serum progesterone profile obtained on day 0 and day 21 postpartum was statistically non-significant between groups. However, it was significantly (p less than 0.05) lower on day 0 as compared to day 21 in group-I, II and VI. The levels on day 0 coincided with the time of blood sampling after calving. The high level of serum P4 on day 0 in group-IV and V could be due to sampling immediately after calving. The serum calcium and phosphorus levels were significantly(p less than 0.05) lower on day 0 than on day 21, but not the magnesium. The group effect was however non-significant for any of three minerals. It was observed that manual removal of RFM without parenteral antibiotics, resulted in puerperal metritis, cervicitis, pyometra which ultimately resulted into delayed uterine involution, delayed first postpartum estrus and thus, reduced the postpartum reproductive efficiency. It was inferred that the PGF2α and Oxytocin injections could be used as a treatment of choice for prevention of RFMs in cattle.

Farm Economics

In beef herds, increasing animal welfare, improving reproductive performance and easing animal management are key goals in farm economics. We explored whether delaying the removal of the intravaginal progesterone device by 24 h in heifers synchronized with a 5d Co-synch 72-h protocol could improve reproductive efficiency of fixed-time artificial insemination (FTAI). In experiment 1, we examined the total synchronization rate (TSR) in cycling Holstein heifers. Heifers (13.4 ± 0.69 mo.) were randomly assigned to the standard 5d Co-synch 56-h protocol (5dCo56; n = 10), 5d Co-synch 72-h (5dCo72; n = 17), or the modified 5d Co-synch 72-h protocol, in which removal of the progesterone device was delayed by 24 h (6dCo48; n = 19). In experiment 2, 309 cycling beef heifers on 18 commercial farms were subjected to the 5d Co-synch 72-h or 6-d Co-synch 48-h protocol and conception rate (CR) studied. In experiment 1, the three protocols led no differences on TSRs of 80.0% (5dCo56), 88.2% (5dCo72), and 89.5% (6dCo48). In experiment 2, the CR from the beef heifers, observed during two consecutive reproductive seasons did not differ: 59.7% for 5dCo72 and 62.0% for 6dCo48 (p = 0.907). Therefore, delaying removal by 24 h provides satisfactory results without reducing reproductive efficiency of heifers.
