“…The study conducted by Janovick et al (2011) where they fed 80% (low), 100% (restricted) and 150% (high) of NRC requirements during pre-partum period found that feeding above NRC requirements resulted into increased mobilization of fat reserves and incidence of metabolic disorders as compared to restricted and under low fed cows during pre-partum period. Tanemura et al (2016) reported that with the increase in fat deposition rate (60% or higher) on liver increases the death or culling rates (69.7 %) and also increased the ovarian disease recurrence rates (84.9%). This further explains why in our study the low pregnancy rate and higher mortality observed in treatment High.…”

Improved feeding during pre-calving phase affects the Body Condition Score (BCS) that subsequently dictate the postcalving productive and reproductive performance. The objective of this study was to investigate the effect of three levels of concentrate supplementation [0.5, 1.0 and 1.5% of body weight (BW)] during pre-calving period on post-calving reproductive and lactation performance in Nili Ravi buffalo heifers. Twenty-six pregnant Nili-Ravi buffalo heifers at 150 ± 20 [Mean ± standard deviation (SD)] days in pregnancy with (BW=516± 57 KG, BCS (1-5) =3.98± 0.18) were selected and divided into three treatment groups; Low (n=8), Medium (n=9) and High (n=9) and allocated three dietary treatments. The treatments were basal diets composed of green fodder [dry matter (DM) = 2.0% of body weight (BW)] with three levels of Concentrates (CP=20.9 %, ME= 2.62 Mcal/kg) i.e. 0.5 (Low), 1.0 (Medium), and 1.5% (High) of the BW. The animals received same feed (forage DM at the rate of 2% of BW and concentrate at 0.5 kg per liter of milk produced on as fed basis) after calving. Increasing concentrate supplies from 0.5 to 1.5% of BW increased pre-calving dry matter intake (DMI), however, it didn't affect BW and BCS at calving. Increased concentrate supply at 1.5% of BW resulted in decrease in post calving conception rate to 33% as compared to 75 and 77.8% at 0.5 and 1.0% of BW concentrate supply. The treatment High decreased lactation length (15%) and yield (17%) as compared to Low and Medium treatment. Pre-calving supplementation of concentrate beyond 0.5% of BW showed no improvement of postcalving productive and reproductive performance. In the given dietary situation, the Nili Ravi heifers didn't require more than 0.5% of BW concentrate along with 2.0% of BW green fodder DM during post 150 days of pregnancy.

RESUMOObjetivou-se avaliar prevalência de cistos ovarianos em vacas leiteiras de alta produção, no pós-parto, submetidas ao regime de dieta total em três sistemas diferentes: Compost Barn, Free Stall e confinamento a céu aberto no sudoeste do estado de Goiás. Foram avaliadas 1600 vacas, HPB, de sete rebanhos, das quais 792 (49,5%) estavam vazias e com atraso nos protocolos reprodutivos. Ao exame ultrassonográfico o escore ovariano foi classificado em: Grau 1 (61,4%), Grau 2 (18,1%), Grau 3 (4,0%) e Cistos Ovarianos (16,5%). Quanto ao sistema de produção as prevalências de cistos foram: 16% no Free Stall, 17,2% no Compost Barn e 16,2% no confinamento a céu aberto, diferenças somente numéricas, mas não significativas estatisticamente. 84,7% (n=131) dos animais estavam em anestro, na presença do diagnóstico cisto folicular. 67,7% desses animais, situavam-se entre 60 a 180 dias pós-parto. Divididos em 27,5% entre 60 e 90 dias, 24,5% entre 91 e 120 dias, 15,5% entre 121 e 150 dias e 32,5% entre 151 e 500. A prevalência dos cistos em função do número de lactações foi: 29,8% na primeira, 26,7% na segunda, 24,4% na terceira, 5,3% na quarta, 4,6% na quinta e 9,2% na sexta, resultados estatísticos significativos para maior ocorrência de cistos nas três primeiras lactações. Quanto ao escore de condição corporal 62,6% das vacas com cisto ovariano mostraram-se com escore entre 2,0 a 2,5, 25,2% entre 2,6 a 3,0 e 12,2% entre 3,1 a 4,0, resultados significativos, e a chance de vacas em balanço energético negativo desenvolverem cistos foi 5,1 vezes maior, quando comparadas com animais em escore corporal ideal. Os cistos foliculares apresentam-se com elevada casuística em vacas de alta produção leite, impactando em subfertilidade e prejuízos importantes na pecuária leiteira mundial, assim, faz-se necessário outros estudos visando o desenvolvimento de medidas preventivas mais eficazes no controle deste quadro. ABSTRACTThis study aimed to evaluate the follicular cysts prevalence in high production dairy cows, post-partum, under total diet regime in three different systems: Compost Barn, Free Stall and opened feedlot. There were evaluated 1600 cows, HPB, seven flocks, of which 792 (49.5%) were empty and late in the reproductive protocols. The examination sonographic ovarian score was distributed as: Score 1 (61.4%), Score 2 (18,1) Score 3 (4.0%) and Cystic Ovary (16.5%). As for the production system the cysts prevalence were 16% in Free Stall, 17.2% in Compost Barn and 16.2% in opened feedlot, without significant difference. 84.7% (n = 131) of animals were in anestrus in the presence of diagnosis follicular cyst. 60.7% of animal with follicular cysts were 60 to 180 days postpartum. Divided in 27.5% between 60 and 90 days, 24.5% between 91 and 120 days, 15.5% between 121 and 150 days and 32.5% between 151 and 500 postpartum. The cysts prevalence according to lactation number were: 29.8% in first, 26.7% in second, 24.4% in third, 5.3% in fourth, 4.6% in fifth and 9.2% in sixth, statistically significant results to higher cysts occurren...

“…Fatty liver is the major cause of periparturient diseases [ 4 , 29 , 30 ] and reproductive disorders [ 5 , 20 , 25 ]. We have previously demonstrated that dairy cows with moderate or severe fatty liver after parturition tend to develop various secondary diseases, including follicular cysts, and many become disused and are culled within a year [ 26 ]. It has been reported that approximately 23% of the first follicular waves after parturition [ 2 , 3 ] or in the early postpartum period [ 21 ] become follicular cysts in dairy cows.…”

Uridine 5’-diphospho-glucuronosyltransferase (UGT) liver activity was measured using estradiol-17β as a substrate in dairy cows with follicular cysts. The activity was significantly lower than that in dairy cows with normal estrous cycles (P<0.01). Liver disorders, such as fatty liver and hepatitis, were observed in half cows with follicular cysts, and liver UGT activity was lower than that in cows with normal estrus cycles. In addition, the liver UGT activity was significantly lower in dairy cows with follicular cysts without liver disorders than in dairy cows with normal estrous cycles. Therefore, the cows were divided into those with low, middle and high liver UGT activities, and liver disorder complication rates were investigated. The complication rate was significantly higher in the low- (78.1%) than in the middle- (22.2%) and high-level (8.3%) groups, suggesting that liver disorders are closely associated with the development of follicular cysts in dairy cows and that steroid hormone metabolism is delayed because of reduced liver UGT activity, resulting in follicular cyst formation. We conclude that reduced estradiol-17β glucuronidation in the liver and liver disorders are associated with follicular cyst occurrence in dairy cows.
