Body condition scoring (using a 5-point with quarter-point divisions) was performed on 66 Holstein dairy cows that began their second or later lactation in August, September, or October 1988. Cows' body condition was scored beginning on postpartum day 4 (+/- 1) and subsequently at postpartum days (+/- 1) 18, 32, 46, 60, 73 and 87. Blood samples were obtained on the same dates. Reproductive health examinations were conducted by 1 of 2 veterinarians beginning at postpartum day 21. Reproductive performance was evaluated in relation to body condition score and serum urea nitrogen and cholesterol concentrations. Number of days to first recorded signs of estrus and first breeding were not related to body condition score at calving, amount of condition loss, cumulative 80-day milk yield, or 305-day fat corrected milk yield. Cows that calved with body condition score greater than or equal to 3.50 required more days to conceive. Cows losing > 0.75 points of condition had longer days of conception. Body condition score at calving and amount of condition lost were not related to services per conception or diagnosis of follicular cyst. Cumulative 80-day milk yield was not related to days to conception or services per conception. Cows that produced greater than or equal to the mean 305-day milk yield required more services and had longer days to conception than cows that produced < the mean 305-day milk yield. Cows with diagnosis of ovarian follicular cysts had greater cumulative 80- and 305-day milk yields than did cows that were not diagnosed with follicular cysts. Cows conceiving with less than or equal to 2 services did not differ in average daily milk production, body condition score, or serum urea nitrogen concentration from cows conceiving with > 2 services, but cows that conceived with less than or equal to 2 services had higher serum cholesterol values than did cows requiring more services.

Epidemiologic relations were evaluated between plasma concentrations of nutrients and cardiovascular diseases. A total of 220 cats were assessed: 144 cats with noninduced acquired heart disease and 76 clinically normal cats. Plasma was assayed for taurine, alpha-tocopherol, selenium, retinol, and total cholesterol and triglycerides concentrations. Cardiovascular disease groups included dilated cardiomyopathy (n = 53), left ventricular hypertrophy (n = 28), hyperthyroidism (n = 11), and uncertain classification (n = 52). In cats with dilated cardiomyopathy, mean plasma taurine concentration was the lowest of that in cats of any group, being only 38% of the value in healthy cats; females had less than half the mean value of males. Tocopherol concentration was 20% lower than normal, and retinol concentration was 40% higher than normal. Total cholesterol concentration was 36% lower than normal. Triglycerides concentration was higher in these cats than in any other group-twice the value recorded in healthy cats and 67% higher than that in hyperthyroid cats. In cats with hypertrophic cardiomyopathy, almost 15% had mean plasma taurine concentration < 30 micromol/L. Retinol concentration was 15% higher, and triglycerides concentration was 54% higher than normal. Approximately 27% of hyperthyroid cats had mildly decreased plasma taurine concentration. Hyperthyroid cats had the lowest tocopherol and cholesterol values; both were at least 30% lower than normal. Retinol concentration was 30% higher than Approximately 14% of cats with uncertain classification had mildly decreased plasma taurine concentration. Plasma retinol and triglycerides concentrations were higher than normal in 25 and 38% of these cats, respectively. Plasma selenium concentration, compared between healthy cats and cats with cardiac disease, was not significantly different. This observation may not be meaningful, however, in light of the limited number of cats in which selenium was assessed.

Effect of different levels of organic chromium on egg yolk cholesterol and chromium contents.

Palod, Jyoti | Kumar, A. | Singh, V.S. | Shukia, P.K.
Afeeding trial was conducted in layers for a period of8 weeks (23-30 weeks old) to evaluate the effect of chromium picolinate supplementation on egg yolk cholesterol and egg chromium content in layers.Atotal of (n=120) layers were randomly distributed in completely randomized design into 4 treatmentgroupseachwith2 replicates of 5chicks.The layers of treatment group T1(control)were provided water without chromiumwhile those of T2,T3andT4were provided water containing 200, 400 and 600 ppb chromium / litre respectively.At the end of feeding trial, six eggs from each replicate, on last three days were used for egg yolk cholesterol and egg chromium studies. The results indicated that the total cholesterol andLDL cholesterol content of eggs were significantly (P0.05) reduced and HDL-cholesterol content significantly increased in 400 and 600 ppb chromium supplemented group of layers. Whereas chromium content of eggs increased with increasing levels of chromium supplementation. It was concluded that organic chromium supplementation up to 600 ppb level through water may be advisable to reduce egg yolk total cholesterol and LDL- cholesterol and improved HDL-cholesterol and egg chromium content.

2003
Bhatti, B.M. | Talat, T. | Sardar, R. (Poultry Research Inst., Rawalpindi (Pakistan))
In this study five samples each of serum glucose, serum cholesterol and uric acid contents were measured in Fayoumi, Rhode Island Red, Parent desi, desi Fl and desi F2 strains of chickens. Cholesterol contents were found to be lowest in desi F2 chickens whereas in other strains there was least significant difference, which can be attributed to reduced lipogenic activity in desi F2 generation. When five samples each of meat from two locations i.e. breast and thigh was subjected to proximate analysis it was found that there was no difference (P greater than 0.05) in crude protein, crude fat, total ash and moisture contents regardless of sex and strains. Dry matter contents differed (P less than 0.05) in breast meat and found to be lowest in Parent desi stocks.

O presente trabalho teve por objetivo avaliar os efeitos da colestiramina e da lovastatina, drogas hipolipemizantes, sobre a qualidade do ovo, desempenho das aves, teores de lípides plasmáticos e de colesterol na gema do ovo de galinhas poedeiras Shaver. Aves com 26 semanas de idade receberam como alimentação dieta formulada sem ingredientes de origem animal (COM) acrescida de colestiramina a 0,2% (COL1) e 0,3% (COL2) e lovastatina a 0,005% (LOV) durante 6 semanas. A adição das drogas não prejudicou a qualidade da casca e do albúmen dos ovos. De um modo geral, o desempenho produtivo das aves não foi afetado, com exceção da redução observada no peso médio dos ovos. Não foram observadas mudanças nos teores de lípides plasmáticos das aves e a concentração de colesterol na gema permaneceu inalterada mediante a adição das drogas. | The purpose of this study was to evaluate the effect of cholestyramine and lovastatin, lipid-lowering agents, upon egg quality, reproductive performance, plasma lipids and egg yolk cholesterol levels of Shaver laying hens. Twenty-six-weeks-old hens were fed basal diet without animal products containing 0.2% cholestyramine (COL1), 0.3% cholestyramine (COL2) or 0.005% lovastatin (LOV) for 6 weeks. It was observed that the supplementation of the drugs did not impair albumen and shell quality. Hen performance was not adversely affected, with the exception of the significant reduction (p < 0.05) in egg weights. No significant changes were observed on plasma lipids, and egg yolk cholesterol remained unchanged with the addition of the drugs.
