“…2 Markusfeld et al 8 and Roche et al 9 also reported a significant rise in milk production with an increase of BCS at calving. Contrary to the present findings, Jilek et al 23 reported that milk production was the highest in cows with BCS before calving less than 4, than in cows with BCS more than or equal to 4. 23 Balkrishnan et al 24 also observed that BCS higher than 3.5 was detrimental to milk yield in crossbreed cows.…”

Abbreviations: BCS, body condition score; SE, standard error; SNF, solids not fat IntroductionBody condition score (BCS) is a subjective measure of body energy reserve and is used as an indirect indicator of energy balance status. 1 It is a quick, non-invasive, inexpensive, visual and tactile way of assessing the degree of fatness of dairy animals 2 and it is recognized by the animal scientists and producers as an important factor in dairy bovine management. 3 Optimal body condition of dairy cow is important for obtaining elite herd and quantity milk production because low or excessive body energy reserve may have a greater risk of lower milk yield and higher milk somatic cell count, SCC. 4 Therefore, the ideal BCS of dairy animals throughout lactation not only optimizes milk yield, but also maximizes economic return. 5 Studies relating the effect of BCS on milk production and milk composition have provided inconsistent results. Ruegg & Milton, 6 and Domecq et al. 7 reported no significant effect of BCS at calving on subsequent milk production, while Markusfeld et al. 8 and Roche et al. 9 reported the contrary to the previous findings. Singh et al. 10 and Lents et al. 11 stated that BCS did not influence fat, SNF and specific gravity of milk, while Doreau et al. 12 reported high milk fat in fatty animals. However, negative correlation between BCS and milk yield, fat and SNF was observed by Mustaq & Quereshi. 13 Dairy cows with high milk yields have been displaying higher incidence of mastitis 14 that can be assessed by SCC or somatic cell score (SCS, log-transformed SCC) in milk. 15 Therefore, SCC is widely used as a marker to determine the udder health and quality of milk. 16 Very few studies have attempted to quantify the relationship between BCS and SCC. 6 Body condition score had a favorable correlation with SCS, but it was not strong, 4,17 while others 2,6 reported insignificant relationship between BCS and SCC. Hence, it is argued that there are no consistent results regarding the relationship between body condition score and milk yield, milk composition and milk somatic cell counts, viz. udder health status of dairy animals. Therefore, the present study was carried out to investigate the effect of body condition score on milk yield, milk composition and udder health status in terms of milk SCC of dairy bovines. Materials and methodsThe experiment was conducted in and around the Narendra Deva University of Agriculture and Technology, Kumarganj, Faizabad (Uttar Pradesh) to assess the effect of body condition score on milk yield, milk composition and udder health status of dairy bovines. In total, 100 lactating dairy bovines of second parity were selected from the Teaching Livestock Farm, the Narendra Deva University of Agriculture and Technology, Kumarganj, and from small dairy farms of nearby villages. The animals were selected randomly and observed for 4months. The data were collected at fortnightly intervals. Milking was done twice daily by hand-milking method. Body condition score of animals a...

“…High milk production, several health disorders, retained placenta, mastitis, and low body condition score decreased fertility in dairy cows (Vacek et al, 2007;Jílek et al, 2008). Many attempts including oestrus synchronization and timed artificial insemination protocols have been made to increase dairy cow fertility.…”

AbstRAct:In several studies, hormones such as gonadotropin-releasing hormone (GnRH), prostaglandins and oxytocin were used to increase pregnancy rate by inducing ovulation and improving the sperm transport in the female reproductive tract in lactating dairy cattle. The objective of this study was to compare the effects of GnRH, prostaglandin F 2α (PGF 2α ) and oxytocin treatments at the time of artificial insemination (AI) after spontaneous oestrus on the conception rate (CR) of lactating dairy cows. Oestrus was detected by visual observations by experienced personnel. All cows (n = 430, 308 Holstein-Frisian and 122 SwedishRed dairy cows) were inseminated based on the am/pm rule by veterinarians of the farm. After AI, cows were alternately assigned to one of the four treatment groups: (1) GnRH (n = 113); (2) PGF 2α (n = 106); (3) oxytocin (n = 106) and (4) non-treated control (n = 105). Pregnancy diagnosis was performed 28-34 and 58-64 days post-insemination by transrectal ultrasonography. Conception rates on days 28-34 and 58-64 were not different among GnRH (46.0%; 52/113 and 44.3%; 50/113), PGF 2α (37.7%; 40/106 and 35.9%; 38/106) and control (49.5%; 52/105 and 47.6%; 50/105) groups. However, conception rates were lower (P = 0.02) in oxytocin (31.1%; 33/106 and 30.2%; 32/106) than in GnRH and control groups on days 28-34 and 58-64. Other covariant factors, such as milk production, days in milk (DIM), breed, parity, service number did not affect the conception rate. Thus, there were no beneficial effects of treatments with GnRH and PGF 2α at the time of AI, and oxytocin had an adverse effect on CR in lactating dairy cows in this study.

“…It is often problematic in non-living industrial or laboratory equipment, the more so in living animals and particularly in ruminants. Therefore it is necessary to pay great attention and time to steady state, and besides the steady state of feeding all other parameters including the body condition of animals Jílek et al, 2008), genetic and nongenetic factors (Fiedlerová et al, 2008) and others should be compared.…”

AbstrAct:The content of organic matter labile fractions is negligible in cattle faeces but the content of the anaerobically degradable fraction on the boundary of organic matter lability and stability is analytically utilizable and different. It depends not only on feed quality and quantity but also on all factors of enteric fermentation and processes determining the digestion of ruminants. In the present paper we attempted to describe the digestive tract of ruminants as an anaerobic bioreactor and to calculate its mass balance so that the measurement of a difference in the anaerobic degradability of feeds and faeces at steady state could be theoretically demonstrated as a multipurpose research method not bothering the animals. The first results in eight variants proved that feed quality and other factors influencing processes in the digestive tract of ruminants could be monitored in this way. Obviously, this method does not replace the present methods used for feed digestibility determination.
