Concentrations of total cholesterol and progesterone were measured in early lactating dairy cows fed either a control diet or a diet containing a protected fat (1.8% on a OM basis) between weeks 4 and 12 post pactum. All cows were fed the control diet from parturition to week 4 post partum. Plasma samples were collected twice weekly. Plasma total cholesterol and progesterone were greater in cow...

The effect of ascorbic acid deficiency on serum levels of high density lipoprotein- (HDL-), low density lipoprotein- (LDL-), very low density lipoprotein- (VLDL-) and chylomicron-cholesterol was examined in ODS-od/od rat (ODS rat), that is a rat mutant unable to synthesize ascorbic acid. Male ODS rats were fed an ascrobic acid-free diet for 20 days. In another two groups, the diet supplemented ...

Forty-five Angus steers (avg initial wt 330 kg) were individually fed for 112 d to assess the value of supplemental Zn and source on performance and carcass quality. Steers had ad libitum access to a control diet (81 ppm Zn) of 33% whole corn, 33% ground milo, 15% cottonseed hulls and 13% cottonseed meal, or this control diet with 360 mg Zn/d added from either zinc methionine or zinc oxide. Ste...

The atherogenic potentials of peeled grated cocoyam (Xanthosoma maffafa scot) "ekpang nkukwo", pounded yam (Discorea spp) with plain soup "afia efere", and plantain porridge (Musa paradisiaca) "iwuk ukom" meals were investigated. The three meals were fed to three different groups of albino rats of Wistar strain for a period of twenty eight days. A fourth group which served as control was feed w...

The current study was conducted to evaluate effects of sequential or wet feeding programs subsequent to and early meal feeding regime on performance, carcass characteristics and humoral immunity in broiler chicks. 192 Ross 308 chicks (seven-day old) were allocated to four treatments at four replicates (12 chicks per plot) based on a Completely Randomized Design. Treatments were included: contro...

Thylakoid membranes derived from green leaf chloroplasts affect appetite-regulating hormones, suppress food intake, reduce blood lipids and lead to a decreased body weight in animals and human subjects. Thylakoids also decrease the intestinal in vitro uptake of methyl-glucose in the rat. The aim of this study was to investigate the effect of dietary thylakoids on the gut microbiota composition,...

in this study the effects of mesolites from moghueieh region and their particles size on performance, blood biochemical parameters and nutrient digestibility in broiler chickens were evaluated. the experiment was conducted on a completely randomized design with three treatments: without mesolite (control) and with fine particle mesolite (passed of 1 mm sieve and stay in 0.225 mm sieve) or large...

this study evaluated the effects of probiotic, lactobacillus plantarum on serum biochemical and some immune parameters of immunized rainbow trout weighting 29.6±1.84 g, with streptococcosis/lactococosis vaccine at 16±1.5°c, for 60 days. a commercial diet was used as the control. fish in the first treatment were immunized with streptococcosis/lactococosis vaccine in bathing route for 1 min. in t...

Two studies were conducted to assess the energy content of low-solubles distillers dried grains (LS-DDG) and their effects on growth performance, carcass characteristics, and pork fat quality in grow-finish pigs. In Exp. 1, 24 barrows (Yorkshire-Landrace × Duroc; 80 to 90 d of age) in 2 successive periods were assigned to 1 of 6 dietary treatments. In individual metabolism stalls, pigs were fed...

a feeding trial of 120 days duration was conducted to study the effect of replacing 20 and 25 % of camel ration by poultry litter (pl) on the performance and some blood biochemical parameters. fifteen healthy one–humped camels were allotted into three groups (5 animals / group). the first group was fed a basal ration and considered as control, while the second and third groups were fed rations ...
