An undisturbed re-organisation of the cervix postpartum is a basic pre-condition for an undisturbed puerperium (Wehrend et al., 2003). This aspect of the puerperal involution has been insufficiently considered in the literature. It was shown that some cows developed a disorder of the cervical involution (Wehrend and Bostedt, 2003). LeBlank et al. (2002) concluded that the size of cervix in cows with clinical endometritis were associated with a decrease in pregnancy rate. With the use of the ultrasonic technique instead of using fingers of the human hand, more exact data on cervix regression can be delivered. Meanwhile, little is known about the effect of diet on cervix regression after parturition. The objective of this study was to evaluate the effect of palm oil fatty acids on cervix regression during the first 40 days postpartum in Iranian Holstein dairy cows using ultrasonic technique.

This study quantifies the effects of extruded linseed and soybean (ELS) dietary supplementation on milk yield, composition, and fatty acid profiles, as well as first-service conception rate in Holstein dairy cows. Seventy-eight open Holstein dairy cows were divided into two groups: (1) a control, which received a basal diet; and (2) a test group, which received a basal diet supplemented with the ELS (650 g/kg of extruded linseed and 150 g/kg of extruded soybean) at a rate of 100 g/kg. In the ELS group, milk yield per day and solid not fat (SNF) yield increased by 3.26% and 0.88%, respectively, in relation to the control. Percentage milk fat decreased significantly by 1.4% in the ELS group when compared with the control. The ELS supplement resulted in a decrease in saturated fatty acids (SFAs) and an increase in monounsaturated (MUFAs) and polyunsaturated fatty acids (PUFAs) in milk. In conclusion, the supplementation of dairy cow feed with 100 g/kg of ELS increases milk yield and milk unsaturated fatty acids (especially MUFAs and PUFAs). ELS supplementation also causes a decrease in percentage fat and SFA levels but does not affect the first-service conception rate or the incidence rate of mastitis.

AbstractThe objective of this study was to compare the effect of two different preventive protocols, on serum β-hydroxybutyrate (BHB) concentration and liver health indices pre-partum and during early-lactation in high-yielding Holstein dairy cows. One hundred cows were randomly divided into three groups: control group (CTRL, n = 20, without preventive treatment), second group (SUPP, n = 40 animals treated with a compound based on acetyl-methionine, inositol, cyanocobalamin, l-alanine, l-arginine, l-threonine, l-glutamic acid supplementation and α-lipoic acid) and third group (MON, n = 40 animals treated with monensin). Blood samples were collected from all cows at on 3 occasions pre-partum and 3 occasions post-partum. Body condition (BCS) score was evaluated and glucose, non-esterified fatty acids (NEFA), BHB, triglycerides, total cholesterol, alanine aminotransferase (ALT), aspartate aminotransferase (AST), γ-glutamyltransferase (GGT), total bilirubin, total proteins, globulins, albumin and urea concentrations were assessed. Two-way repeated measures analysis of variance was applied. Statistically significant differences among the three experimental groups were found in the values of all studied parameters (P < 0.05). Our results confirm the established beneficial effect of MON treatment in decreasing BHB levels and increasing glucose availability after calving. Serum biochemical analysis revealed the expected post-partum alterations attributable to adaptations that influenced the metabolism and liver function in CTRL, whereas these alterations were reduced or absent in SUPP and MON. Results from the present study suggest that both preventive protocols, but in particular SUPP, could positively affect selected indicators of energy metabolism reducing the risk of hyperketonaemia and increase of liver function in Holstein dairy cows, both pre- and post-partum.

112 selected Friesian dairy cows that had calved at least once, were used. The animals were divided into two groups, A (n = 55) and Β (n=57). On the 12th day post insemination (p.i.) 12 μg buserelin (3ml Receptal - Hoechst) and 3 ml normal saline (placebo) were injected intramuscularly to the animals of groups A and Β (controls), respectively. Milk progesterone concentration was measured in even animal from the day of insemination until the 24th day p.i.. A significant increase (P<0.05) in pregnancy rate (19.7%) was observed in the animals of group A. Also, the concentration of progesterone in the pregnant animals (14th - 24th day p.i.) as well as in the non pregnant (14th - 16th day p.i.) ones in group A was significantly increased (P<0.05) compared to that of the controls'. The duration of the estrous cycle of the non pregnant animals did not differ significantly (P>0.05) between the two groups. It is concluded that buserelin administration on the 12th day p.i. improved the fertility of dairy cows significantly by means of an antiluteolytic effect, through an increase in progesterone concentration, during the crucial period of maternal recognition of pregnancy.
