The Relationship

The objectives of this study were to evaluate the relationship between changes in Holstein cow’s body condition score (BCS), acetone and urea content in the milk and cervical mucus (CM) and sperm survival in CM. At insemination, samples of milk and CM were collected from 64 Holstein cows. Content of acetone and urea were determined. Sperm motility was assessed subjectively at the beginning and after 30, 60 and 90 minutes of the short-term heat test in CM. Data about evaluation of cow’s BCS were taken from farm evidence. The data set was analyzed using SAS/STAT software. Effect of change in cow’s BCS one month before insemination was significant only in relation to the acetone content in milk (P < 0.05). Higher values of acetone and urea content were found in the CM compared to milk. Higher levels of both metabolites were detected in primiparous cows and in cows on the third and subsequent lactation, resp. in cows inseminated 3 times and more. The highest values of both metabolites negatively affected sperm survival during the short-term heat test, especially after 90 minutes (P < 0.05–0.01). Significant decreases (P < 0.05–0.01) were detected in cows with the highest level of acetone and urea.

The objectives of this study were to determine and evaluate effect of breed, age and body condition score (BCS) on qualitative and quantitative parameters of bull’s ejaculate. In total, 16 Holstein (H) and 15 Czech Fleckvieh (F) bulls were collected in September 2009 and May 2010. Volume of semen samples, sperm concentration and percentage of motile spermatozoa were evaluated immediately after collecting. Sperm motility was also evaluated after diluting and freezing/thawing of AI doses and subsequently during the short-term test of sperm survival. Percentages of live and pathologic sperm before diluting also were evaluated. The data set was analyzed using a generalized linear model in SAS/STAT software. A statistically significant effect of the breed, age and body condition on qualitative and quantitative traits of bull’s sperm were determined (P < 0.05–0.01). Sperm activity after collection, dilution and freezing/thawing had significantly decreasing character.

The Relationship

The relationship between changes in body condition score (BCS) during the postpartum and fertility in beef cows suckling calves under extensive conditions were investigated. Cows were subjected to four BCS evaluations over the postpartum period, starting around one month after calving. In the second evaluation cows were treated with medroxy-progesterone acetate impregnated pessaries and received an injection of estradiol benzoate. At the third evaluation, pessaries were removed and calves were separated from the cows for 96 hours, during which time estrous was observed twice a day, and animals artificially inseminated 12 hours after detection. When calves returned to their dams, bulls were introduced until a 60-day mating period was reached. The distribution of BCS differed among calving groups and evaluations. Results indicated that only cows comprising a BCS 3 (1 to 5 scale) around the first month postpartum can be used in an artificial insemination program with possibilities of becoming pregnant. There was no statistical difference between the calving groups in pregnancy rate. The evolution of the BCS of the cows during postpartum can be used to adjust the start of the breeding season to coincide with the time of the year where herd pregnancy rates will be highest.

Abstract This research communication describes the relationship between the occurrence of lameness and body condition score (BCS) in a sample of 288 cows from a single farm that were repeatedly scored in the course of 9 months while controlling for confounding variables. The relationship between BCS and lameness was evaluated using generalised linear mixed-effects models. It was found that the proportion of lame cows was higher with decreasing but also with increasing BCS, increased with lactation number and decreased with time since the last claw trimming. This is likely to reflect the importance of sufficient body condition in the prevention of lameness but also raises the question of the impact of overcondition on lameness and the influence of claw trimming events on the assessment of lameness. A stronger focus on BCS might allow improved management of lameness that is still one of the major problems in housed cows.

The purpose of this retrospective study was to evaluate the relationship between occlusal and clinical parameters and the need for incisor shortening in horses. It was based on the retrospective analysis of the dental charts of 75 confined horses. Body condition score, shape of incisors, presence of dysmastication, excursion to molar contact (EMC) distance before and after cheek teeth occlusal adjustment were evaluated. History of difficult to riding, dysmastication and digestive problems was also considered. The initial measurement of lateral excursion to molar contact (EMC) revealed incisor occlusal surface abnormalities in 45 (60%) horses and long incisors (EMC>15mm) in five (6.6%) horses. Considering clinical examination and history data the need for reduction of incisor length was significant when EMC exceeded 15mm (P<0.0001) and when based on dental shape, clinical history of dysmastication and/or digestive problems or body condition score was also significant (P<0.05). In confined horses, the decision to shorten and align the incisor teeth should be based on observation and history of dysmastication and digestive problems, body condition score, incisors shape and EMC distance. The need for incisor reduction should be determined before dental intervention and reassessed following cheek teeth oclusal adjustment

ABSTRACTAn analysis of the records of ewe weight and condition at mating together with subsequent lambing performance for several commercial flocks in the UK revealed no significant relationship between lambing performance and size, measured by weight transformed to a standard condition. The relationship between mating weight and body condition score at mating was linear though there was considerable variation in weight at a fixed body condition, suggesting a substantial spread in skeletal size. Increases in ovulation rate were not discernible from lambing figures over the range of body conditions observed in these flocks.

In this study, it was aimed to determine the number of pregnancies and infants by B-Mod Real Time 3.5 MHz linear transabdominal probe ultrasonography device on the 50th day of pregnancy in 126 head Karayaka sheep. In addition, the relationship between body condition score and fry birth weight was tried to be determined on the 50th day of pregnancy and sheep age. The findings obtained by ultrasonography device were compared with the lambing records. In this study, the accuracy of ultrasound examination was 84% and sensitivity was 93%. The correlation coefficient between the average body condition score of the sheep on the 50th day of pregnancy and birth weight of the offspring was calculated as 0.234 and it was found to be statistically significant. It was determined that there was a significant relationship between the sheep age and the body condition score at the 50th day of pregnancy.

The aims of this research were to observed the effect of zinc (Zn), magnesium (Mg) and selenium (Se) to the abundance, color and spinnbarkeit of cervical mucus. The materials used 10 Timor deer with BCS (Body Condition Score) 2-3,25, poel 2 and had different estrous phase. The parameters were observed the abundance, color and spinnbarkeit of cervical mucus. The data of abundance and color of cervical mucus were analyzed by Mann Whitney U-test and the data of spinnbarkeit were analyzed by t-test. The treatments were zinc (Zn), selenium (Se) and magnesium (Mg) supplementation (T1) on mineral block form and control (T0). The results showed that Zn, Se, and Mg supplementation had no significant effect (P>0,05) to the abundance, color and spinnbarkeit of cervical mucus Timor deer on estrous phase. It was caused by the high zinc level on feed, so the cervical mucus profile had no difference between T0 and T1.Key words : Mineral Supplementation, Cervical Mucus, Timor Deer

Strategic Feeding

Strategic short-term feeding of culled Malpura ewes (age >6 years, average liveweight 26.8 ± 0.96 kg) was aimed at improving their body condition and increase marketability of their carcass following slaughter. Randomly, 8 out of 40 ewes were slaughtered to study initial (Day 0) carcass traits and the remaining ewes were equally divided into two groups: mustard cake (Control) and urea. They were stall fed with ad libitum guar straw (Cyamopsis tetragonoloba) and concentrate mixture at 25 g/kg liveweight after 4 h of morning grazing in the pasture. The Control group was offered concentrate with solvent extracted mustard cake whereas it was replaced on an equivalent nitrogen (N) basis with urea in the concentrate offered to the other group. Daily feed intake and weekly change in ewe liveweight and body condition score were measured during the 91 days of the experiment. There was no significant (P > 0.05) difference in digestibility of nutrients between the groups. Both groups had similar dry matter and metabolisable energy intake, but the mustard cake group recorded higher (P < 0.05) cumulative weight gain and body condition score. Ruminal fluid samples and blood biochemical measurements were analysed periodically (0, 45 and 91 days), with ruminal fluid samples during the post-feeding hours also analysed. There was periodic variation in rumen pH (P = 0.013), volatile fatty acid (P = 007), total N (P = 0.001) and ammonia-N (P = 0.025) concentration in both groups. Higher post-feeding volatile fatty acid (P = 0.031) and total N (P = 0.003) values were observed in the mustard cake group. Ruminal ciliate protozoal population showed a quadratic response over time after feeding with an initial decline post-grazing, but was not affected by treatment. Similar significant (P < 0.05) improvements in haemoglobin, glucose, total protein, urea and cholesterol levels were evident in both groups at 91 days. Both treatments showed similar improvement in carcass composition, distribution of fat and chemical composition of Longissimus dorsi after 91 days of realimentation compared with initial values. Short-term pre-slaughter feeding of cull ewes improved body condition, carcass traits and composition. Replacement of costly mustard cake with urea in the diet of cull ewes could be a means to improve profitability of this strategic feeding protocol, as well as enhancing their market value.
