We previously showed that 3-methyl-4-nitrophenol (4-nitro-m-cresol, PNMC), a component of diesel exhaust particles and a degradation product of the insecticide fenitrothion, has reproductive toxicity in adult male and immature female Japanese quail (Coturnix japonica). Here we investigated effects of PNMC on the reproductive toxicity of mature female Japanese quail. The experiment consists of 3...

Twenty-three of indigenous Priangan and Javanese Fat-tailed (JFT) ram breeds were used to evaluate its carcass and non carcass components slaughtered at mature live weight. Five Priangan rams and six JFT rams were slaughtered at 32.5 kg of live weight while six other rams of each breeds were also slaughtered at 40 kg of live weight. Before the rams were slaughtered, they were fattened using pel...

Background: Pesticides are used frequently and may have various adverse effects on human health in different ways. Cypermethrin (CYP) is a synthetic type II pyrethroid pesticide that has been used extensively to control a wide variety of pests in agriculture, forestry, horticulture, and public health. Objectives: This study aimed to investigate the dose-dependent hematological, hepatic and gona...

Our objectives were to determine the effects of dam body condition score (BCS), age dam, and calf sex on placental size relationships between weight (BW) with size. Expelled placentas at birth collected from crossbred beef heifers cows during four experiments (n = 22 39/experiment). Placentas deemed complete by visual inspection dissected; dry weights determined for cotyledonary intercotyledona...

an experiment was carried out to estimate growth parameters of broiler chickens received artichoke extract in their drinking water using gompertz non-linear model and to compare gompertz non-linear regression equation and artificial neural network modeling in terms of their ability to predict body weight of broiler chicks at day 42 of age. a total number of 250 one- day- old ross 308 broiler ch...

The objective of this study was to evaluate the growth curves of females to determine if mature size and relative rates of maturation among breeds differed. Body weight and hip height data were fitted to the nonlinear function BW = f(age) = A - Be(k×age), where A is an estimate of mature BW and k determines the rate that BW or height moves from B to A. Cows represented progeny from 28 Hereford,...

Mice deficient in brain-derived neurotrophic factor (BDNF) develop mature-onset obesity, primarily due to overeating. To gain insight into the mechanism of this hyperphagia, we characterized food intake, body weight, meal pattern, and meal microstructure in young and mature mice fed balanced or high-fat diets. Hyperphagia and obesity occurred in mature but not young BDNF mutants fed a balanced ...
