In early lactation dairy cattle suffer metabolic alterations caused by negative energy balance, which predisposes to fatty liver and ketosis. The aim of this study was to evaluate the metabolic condition of high yielding dairy cows subjected to three treatments for preventing severe lipomobilization and ketosis in early lactation. Fifty four multiparous Holstein cows yielding >30 L/day were divided into four groups: control (CN= no treatment), glucose precursor (PG= propylene-glycol), hepatic protector (Mp= Mercepton®), and energy supplement with salts of linolenic and linoleic faty acids (Mg-E= Megalac-E®). Treatments were administrated randomly at moment of calving until 8 weeks postpartum. Blood samples were collected on days 1, 7, 14, 21, 28, 35, 42 and 49 postpartum. Body condition score (BCS) was evaluated at the same periods and milk yield was recorded at 2 nd , 4 th , 5 th , 6 th , 7 th , and 8 th weeks of lactation. Concentrations of non-esteriϐied fatty acids (NEFA), albumin, AST, ß-hydroxybutyrate (BHBA), cholesterol, glucose, total protein, urea and triglycerides were analyzed in blood samples. Cut-off points for subclinical ketosis were deϐined when BHBA ≥1.4 mmol/L and NEFA ≥0.7 mmol/L. General occurrence of subclinical ketosis was 24% during the period. An ascendant curve of cholesterol and glucose was observed from the 1 st to the 8 th week of lactation, while any tendency was observed with BHBA and NEFA, although differences among treatments were detected (p≤0.05). BCS decreased from a mean of 3.85 at 1 st week to 2.53 at 8 th week of lactation (p=0.001). Milk yield was higher in the Mg-E group compared with the other treatment groups (p≤0.05) Compared with the CN group, the treatments with Mp and PG did not show signiϐicant differences in blood biochemistry and milk yield. Cows receiving PG and Mg-E showed higher values of BHBA and NEFA (P<0.05), indicating accentuated lipomobilization. Supplementation with Mg-E also resulted in signiϐicant higher concentrations of cholesterol, BHBA, urea, AST and lower values of glycemia. This performance may be explained by the highest milk yield observed with this treatment. Treatments with PG and Mp did not improve milk yield, compared with control cows, but did not show metabolic evidence of ketosis, fat mobilization or fatty liver. These results suggest that treatment with Mg-E improves milk production but induces a higher negative energy balance leading to moderated lipomobilization and ketone bodies production, increasing the risk of fatty liver.

“…The highest values of this parameter (87.62 g·dm -3 ) were found at the end of the experiment, in cows fed with maize silage covered with oxo-biodegradable foil. As in own studies, other authors (Mordak and Nicpoń, 2006;De Cardoso et al, 2008;Adamski, 2010) observed exceeding of the reference range (Winnicka, 2015) for the evaluated parameter by 18, 23 and 19%, respectively. Adamski et al (2010) showed that the serum total protein level in cows at 8 weeks of lactation decreased as the condition of these animals increased from 84.52 g·dm -3 at BCS (Body Condition Score) 1-3 to 72.38 g·dm -3 of the fatted cows (BCS≥4).…”

In agricultural practice, silage production uses pure, low density polyethylene foil. This foil, after use, becomes farm waste, having a negative impact on the environment. Instead of conventional foil, an environmentally safe biodegradable foil can be used, made from naturally occurring polymers or from synthetic multiparticulates, easily degradable by microorganisms. Silage covered with this type of foil should be safe for animal health. The purpose of the study was to determine whether oxo-biodegradable film could be used instead of conventional film in agricultural practice, to produce silage that is safe for the cows' health. Dairy cows were fed a partly mixed ratio (PMR), the component of which was silage made of whole maize plants, covered with oxo-biodegradable foil. The cow blood serum was marked for content of: glucose, total protein, cholesterol, triacylglycerols and enzyme activity: aspartic and alanine aminotransferase, γ-glutamyl transferase, alkaline phosphatase and amylase. The total protein concentration in the serum of cows analyzed at the end of the experiment was higher than the commonly accepted normal values. The content of glucose, cholesterol, triacylglycerols and the activity of aspartate and alanine aminotransferase, γ-glutamyl transferase, alkaline phosphatase and amylase was within reference limits. Feeding of silage from whole maize plants covered with oxo-biodegradable foil did not negatively affect the biochemical indicators of the cows' blood serum. The silage proved to be safe for the cows' health.Keywords: dairy cows, health status, oxo-biodegradable foil, silage 773Journal Streszczenie W praktyce rolniczej przy produkcji kiszonek wykorzystuje się folię z czystego polietylenu małej gęstości. Folia ta po wykorzystaniu jest w gospodarstwie odpadem, który ma negatywny wpływ na środowisko. Zamiast folii konwencjonalnej może być stosowana bezpieczna dla środowiska folia ulegająca biodegradacji, wyprodukowana z polimerów pochodzenia naturalnego lub z syntetycznych związków wielocząsteczkowych rozkładanych przez mikroorganizmy. Kiszonka okryta taką folią powinna być bezpieczna dla zdrowia zwierząt. Celem badań było ustalenie, czy folia oksybiodegradowalna może być wykorzystana zamiast folii konwencjonalnej w warunkach praktyki rolniczej do produkcji kiszonek bezpiecznych dla zdrowia krów. Krowy mleczne żywiono dawką częściowo wymieszaną (PMR), której komponentem była kiszonka z całych roślin kukurydzy okryta folią oksybiodegradowalną. W osoczu krwi krów oznaczono zawartość glukozy, białka całkowitego, cholesterolu, triacylogliceroli i aktywność enzymów: aminotransferazy asparaginianowej i alaninowej, γ-glutamylotransferazy, fosfatazy alkalicznej i amylazy. Stężenie białka całkowitego w surowicy krwi krów analizowane na koniec doświadczenia, było wyższe niż ogólnie przyjęte wartości prawidłowe. Zawartość glukozy, cholesterolu, triacylogliceroli oraz aktywność aminotransferazy asparaginianowej i alaninowej, γ-glutamylotransferazy, fosfatazy alkalicznej i amylazy mieściły się w gr...

“…No Brasil, este padrão de casuística é mantido, existindo relatos no Estado de São Paulo, onde a relação de DAE e DAD é de 5:1 (Birgel et al 1990), enquanto no Paraná tal relação aumenta para 8 a 9:1 (Reichert Netto 1992). Existem ainda relatos de DA em bovinos leiteiros em Pernambuco (Coutinho et al 2002, Câmara et al 2007, Goiás (Silva et al 2004(Silva et al , 2008, Distrito Federal ) e Rio Grande do Sul (Cardoso et al 2008); enquanto em bovinos de corte, apenas no Distrito Federal (Câmara et al 2009). Assim como outras doenças da produção (metrite, retenção de placenta, cetose, hipocalcemia, mastite, doença cística ovariana), o DA acarreta grande perda econômica na indústria leiteria e diminui o bem-estar animal (Ingvartsen et al 2003, Mullingan & Doherty 2008.…”

ABSTRACT.-Câmara A.C.L., Afonso J.A.B., Costa N.A., Mendonça C.L., Souza M. The continuous genetic selection for high milk production in association with greater digestive capacity and corporal depth increases the susceptibility for abomasopathies including abomasal displacement. The present work aimed to accomplish a retrospective study on abomasal displacement in 36 cattle attended at Bovine Clinic, Garanhuns Campus, Federal Rural University of Pernambuco, through January 2000 to February 2009. Twenty seven cases of right abomasal displacement, six cases of left abomasal displacement and three of abomasal volvulus were diagnosed. Eleven moderate cases, without severe abdominal distention, appetite for roughage and metallic sound ("ping") reaching at the most the 8 th intercostal space were treated conservatively, and 20 severe cases with moderate to severe abdominal distention associated to systemic disturbances were treated surgically. Two cows were euthanized due to diffuse peritonitis or severe alterations in the abomasal serosa totalizing 18 animals submitted to the surgical treatment. Two animals were slaughtered and three cows arrived prostrated and died without receiving any treatment. Risk factor analysis identified rainy season as statistically significant. The greater number of abomasal displacement was in crossbred cows with 24 cases (66.6%), followed by Holstein and Gir cattle with 11 (30.5%) and one (2.9%) cases, respectively. Food composition varied greatly and characterized by excess of carbohydrates and in most cases low quality fibers. Most frequent clinical signs were apathy, dehydration, light to severe ruminal bloat with reduced or absent motility, splashing sound during right flank ballottement, ping and a distended visceralike structure in the side of the displacement; liquid, blackish and fetid feces. Hematology reveals leukocytosis with neutrophilia and hyperfibrinogenemia in most cases. Ruminal fluid analysis showed compromised flora and fauna dynamics and increased chloride ion concentration in 93.9% of the cases achieving the media index of 47.66 mEq/L. Clinical and surgical recovery rate achieved 100% and 72.2%, respectively. Those methods described are viable options for the treatment of light and severe displacements but the prevention remains the best choice.
