A significant factor in improving the performance of dairy cows is their physiological ability to correct a negative energy balance (NEB). This study, using Simmental (SIM) and Holstein-Friesian (HF) cows, aimed to assess changes in NEB (non-esterified fatty acid; body condition score; and C16:0, C18:0, and C18:1) and its effect on the metabolic efficiency of the liver (β-hydroxybutyrate and urea). The effects of NEB on daily yield, production at peak lactation and its duration, and changes in selected milk components were assessed during complete lactation. Up to peak lactation, the loss of the body condition score was similar in both breeds. Subsequently, SIM cows more efficiently restored their BCS. HF cows reached peak lactation faster and with a higher milk yield, but they were less able to correct NEB. During lactation, their non-esterified fatty acid, β-hydroxybutyrate, C16:0, C18:0, C18:1, and urea levels were persistently higher, which may indicate less efficient liver function during NEB. The dynamics of NEB were linked to levels of leptin, which has anorectic effects. Its content was usually higher in HF cows and during intensive lactogenesis. An effective response to NEB may be exploited to improve the production and nutritional properties of milk. In the long term, it may extend dairy cows’ productive life and increase lifetime yield.

There have been few studies on the use of diets and strategies to reduce the length of postpartum anoestrus in dairy goats, especially in tropical semi-arid regions. This review discusses the factors influencing the return of postpartum ovarian activity in goats. During the postpartum period, goats are in puerperal anoestrus and their reproductive tract is being prepared for a new conception. Anoestrus is necessary for tissue renewal in the uterus (uterine involution) associated with the return of cyclic ovarian activity, and is influenced by factors such as suckling of the offspring, social interactions, body condition score (BCS) before and after birth, intensity of negative energy balance (NEB) and stress from adverse climatic conditions. The anoestrus period can be extended by delays in the resumption of reproductive activity of females in puerperium. The duration of puerperal anoestrus in goats directly affects the productivity of the herd and is mainly influenced by nutrition, lactation period and heat stress. To minimize the negative effects of postpartum anoestrus on productivity, we recommend a mating season and a plan for the kidding period, as well as a program to monitor the body condition score during pregnancy so that the animals will have a better BCS at parturition. To minimize the effects of a negative energy balance, we suggest nutritional supplementation with levels of energy above the requirements for maintenance. Highlights The duration of postpartum anoestrus in goats is influenced by nutrition and body condition score. Heat stress can intensify the negative energy balance, consequently increased the period of anoestrus. Puerperal anoestrus occurs as a result of tissue renewal in the uterus. Suckling of the offspring associated with the period of lactation and social interactions can modified the puerperal anoestrus period. Use of diets and strategies to reduce the postpartum anoestrus in goats.

Positive Effect

The objective of our research was to evaluate the effect of some factors on the embryonic mortality of Holstein-Friesian dairy cows in a herd. Monitoring was conducted in the course of three years (2006–2009) at a level of (9330–8970) kg/dairy cow per lactation. We monitored the reproduction parameters of 209 dairy cows (1st to 8th lactation). Ultrasonography was used to diagnose gravidity, and/or embryonic mortality, in each cow 6 times, at regular 4-day intervals between days 22 and 42 after insemination. We analysed the effect of 3 factors on embryonic mortality: age, body condition score and season of the year at the time of insemination. Embryonic mortality relative to the age of the female was significantly the lowest (20.69 %) in cows aged 42 to 47 months (3.5–3.9 years); high embryonic mortality (45.46 %) was recorded in the youngest females of 24 to 29 months of age (2.0–2.4 years). The results indicated that the body condition score of the cow at the time of insemination had a statistically significant (P > 0.01) effect on embryonic mortality (EM). Embryonic mortality was the lowest when the body condition of the cow was “ideal”, i.e. 5 points of the BCS (at the most 9 points). The season of the year when insemination was carried out had a positive effect on embryonic mortality.

Negative Effect

The aim of this study was to confirm that a negative energy balance expressed by declining body condition score (BCS) can lead to the deterioration of fertility results of Czech Fleckvieh cows. The BCS of cows was evaluated before calving and during the first five weeks of lactation. The evaluation was based on 338 Czech Fleckvieh cows calved between the October 13th, 2009 and April 27th, 2010 at one dairy farm. Analysis of relationships between the energy balance results and fertility score expressed by the reproduction results (pregnancy rate after the first and all inseminations, the insemination interval, service period, insemination index, calving period) of the observed group were performed. The higher body condition score of the Czech Fleckvieh cows before calving turned out advantageously regarding the energy source during the postpartal period. No negative effect of higher BCS in cows before calving was confirmed. The best reproduction parameters were attained in the group of cows with no change or marked increase of body condition after calving recorded. However, statistically significant differences between the groups were detected only in the third week of lactation. Significant differences in the level of body condition were detected in relation to the length and type of oestrus onset.

Condition Score

Abstract Our objective was to evaluate the effects of body condition score (BCS) on the milk production and energy balance of transition dairy cows. Seventy-five multiparous dairy cows were separated into four groups according to the BCS, HH (4.25 ± 0.23 and 3.35 ± 0.19 BCS, pre and postpartum, respectively, n = 17), HM (4.14 ± 0.15 and 2.92 ± 0.24, n = 19), MM (3.10 ± 0.21 and 2.78 ± 0.17, n = 23), ML (2.88 ± 0.23 and 2.46 ± 0.19, n = 16). The milk yield, rumen pH, etc., data were collected and analyzed using a one-way ANOVA model in SAS (SAS version 9.4, SAS Institute Inc., Cary, NC, USA). The ML group had a higher milk yield and total solid yield than the MM group (P < 0.05), while the HH and HM groups had no difference with other groups. The HM and ML groups had a higher milk fat content than the MM group (P < 0.05), while the HH group had no difference with other groups. Milk protein content in the HH group was higher than the ML group (P < 0.05). The milk lactose, total solids, urea content in these groups had no difference. The ML group had a higher milk acetone content than the HH group (P < 0.05). The BCS change in the HH and HM groups was higher than the MM and ML groups, and that in the ML group was higher than the MM group (P < 0.05). The rumen pH had no difference within these groups. These findings collectively indicated the prepartum dairy cow with middle BCS would have a more efficient body fat utilization and a better milk production performance. Furthermore, reducing body fat loss is necessary to avoid the negative energy balance.
