Intrapartum death in multiparous gestations in sows (Sus scrofa) is often caused by hypoxia. There is little information in the literature on the assessment of the placenta in relation to intrapartum death in piglets. The aim of this study was to evaluate the impact of the placental area and weight upon piglet birth characteristics and intrapartum death. Litters from 26 Landrace-Yorkshire sows ...

The sheep sector has not suffered the technification that other livestock sectors have. lack of technological knowledge farmers and economic limitations have made this difficult. One most widely used technologies is Precision Livestock Farming (PLF). PLF already been in to improve farming efficiency. In light problem weighing lambs their low precision, paper proposes a system for estimating wei...

OBJECTIVE To investigate the association between the perception of body weight (as above or below the desired) and behaviors for body weight control in adolescents. METHODS This was a cross-sectional study that included 1051 adolescents (aged 15-19 years) who were high school students attending public schools. The authors collected information on the perception of body weight (dependent varia...

Five hundred thirty-four steers were evaluated over a 2-yr period to develop and validate prediction equations for estimating carcass composition from live animal ultrasound measurements and to compare these equations with those developed from carcass measurements. Within 5 d before slaughter, steers were ultrasonically measured for 12th-rib fat thickness (UFAT), longissimus area (ULMA), rump f...

This study examined the effects of various levels of dietary encapsulated choline chloride (ECC) on growth performance, carcass characteristics, serum and liver lipids content in Ross 308 broilers. A total of 480 day-old broilers were assigned to eight dietary treatments with six replicates of 10 birds each from 1 to 21 days of age. Eight experimental diets were provided from a basal non-added ...

　Introduction: Sexual dimorphisms in biological structures such as brain and behaviour have been widely recognized in animals and humans. The purpose of this study was to examine whether there are sex differences in the size of the cerebellum with other body traits, such as the head, tail and brain. Methods: Twelve grasscutters comprising of 6 males and 6 females were used in this study. Each b...

background: different stressors induce learning and memory impairment and physical activity influence learning and memory enhancement. in this research, we investigated the effect of synchronized running activity with stress on acquisition and retention time of passive avoidance test. methods: male wistar rats were randomly divided into five groups as follows: control (co), sham (sh), exercise ...

this study compared the use of five different models to describe the growth from birth to 20 weeks of age of kids from both genders of nondescript goats. fifty nine (59) nondescript kids were weighed weekly at the university of maiduguri livestock teaching and research farm, nigeria and the live weights were modeled. biologically relevant variables were estimated for each kid from the logistic,...

the aim of the present study was the estimation of (co) variance components and genetic parameters for body weight of moghani sheep, using random regression models based on b-splines functions. the data set included 9165 body weight records from 60 to 360 days of age from 2811 moghani sheep, collected between 1994 to 2013 from jafar-abad animal research and breeding institute, ardabil province,...
