. an experiment was conducted by incorporating 35 newborn balouchi lambs to study the effects of different type and levels of forage in starter diets on rumen development characteristics and performance. the 5 experimental treatments were included; starter diet without forage (control) and starter diet containing two levels (7.5 and 15%) of alfalfa hay and wheat straw. inclusion of forages incr...

The gross and microscopic anatomy of the Cape fur seal heart, lung, liver, spleen, stomach, intestine and kidneys (n = 31 seals) is described. Absolute and relative size of organs from 30 male seals are presented, with histological examination conducted on 7 animals. The relationship between log body weight, log organ weight and age was investigated using linear regression. Twenty five animals ...

The Cry1Ia12 entomotoxin from a Brazilian Bacillus thuringiensis strain is currently being expressed in cotton cultivars to confer resistance to insect-pests. The present study aimed to assess the effects of a diet containing Cry1Ia12 protein on growing rats. A test diet containing egg white and Cry1Ia12 (0.1% of total protein) as a protein source was offered to rats for ten days. In addition, ...

Data from 645 normal rabbits were used as the basis of an investigation of the relation existing between body and organ weights. Actual and relative weights were correlated with both gross and net body weight. The results obtained varied with different classes of organs but it was found that, in general, there was an agreement between the form and degree of the correlation shown and the structu...

The objective of this study was to evaluate the effect of different levels of crude cottonseed oil in isoenergetic diets, with or without supplementation of ferrous sulfate, on performance variables, relative weight of organs, and blood parameters of broilers, and on the economic viability of diets in the periods from 1 to 7 and 1 to 21 days of age. A total of 600 male birds of the Ross line we...

objective: a research was carried out to investigate the effects of nettle (urtica dioica) powder (np) and essential oil (ne) on performance, blood metabolites, carcass characteristics and antioxidant stability in broiler chicks. methods: the treatments were t1: control diet, t2: control diet + 5g/kg np, t3: control diet + 10 g/kg np, t4: control diet + 5g/kg ne and t5: control diet + 10 g/kg n...

The study material comprised 3889 foetuses of both sexes, aged 20-42 weeks and focused on developmental interdependence between the weight of the internal organs and their relation to selected somatic features during the prenatal period. The study also attempted to distinguish potential sex-related differences in the degree of statistical interdependence between the analysed variables. As a res...

The present study was performed for investigation on possible effects of exogenous ghrelin (GH-releasing peptide) on liver, heart, gizzard (proventriculus+gizzard), intestine and breast muscle weights. One hundred fertilized eggs were divided into two groups includes control or group1 (without any in ovo ghrelin administration) and group2 (in ovo administration of 100ng/egg ghrelin at day-5). I...
