Within-herd phenotypic and genetic trend lines for milk yield in Holstein-Friesian dairy cows
November 2007
A total of 937 pedigree, breeding and performance records of 567 Friesian cows at the Livestock Experiment Station Bhunikey Dist. Kasur (Pakistan) spanning the years 1982-2001 were analyzed using Best Linear Unbiased Predictions procedure. Individual animal models were fitted to total milk yield from all lactations to estimate breeding values by Restricted Maximum Likelihood methodology. Milk yield and lactation length...
Antilipidemic effect of chitosan against experimentally induced myocardial infarction in rats
November 2007
Myocardial infarction is a major public health concern and the leading cause of death all over the world. A better understanding of the processes involved in myocardial infarction has stimulated the search for new drugs, which could limit the myocardial injury. In the present study, an attempt has been made to examine the preventive effects of chitosan, a marine polysaccharide, on isoprenaline-induced myocardial...
Organic waste treatment for power production and energy supply
October 2007
Sudan is endowed with abundant solar, wind, hydro, and biomass resources. Like many tropical countries, sudan has ample biomass resources that can be efficiently exploited in a manner that is both profitable and sustainable. Fuel-wood farming offers cost-effective and environmentally friendly energy solutions for Sudan, with the added benefit of providing sustainable livelihoods in rural areas. Biogas from biomass...
Detection and mapping of QTL on bovine chromosomes 2 and 5 segregating for live weight, average daily gain and body measurements in Japanese black cattle
October 2007
Bovine chromosomes 2 (BTA2) and 5 (BTA5) of purebred, half-sib progeny sired by five Japanese black bulls were genotyped using microsatellite DNA markers. The data were subjected to linkage analysis for the detection and mapping of segregating quantitative trait loci (QTL) influencing live weight, average daily gain and body measurements at weaning. Probability coefficients of inheriting allele 1 or 2 from the sire at...
Postnatal development of zygomatic glands from guinea pig: a morphological and morphometric analyses
October 2007
The postnatal development of zygomatic glands from guinea pig (Cavia porcellus) ranging from 2 to 140 days of postnatal life was studied by means of morphological and morphometric methods. The results showed that the body weight growth has occurred in two phases from 2 to 7 and from 14 to 140 days. With respect to gland mass, its growth has also occurred in two phases from 2 to 7 and from 14 to 140 days of life....
Effects of four different basal diets on the carcass composition of finishing Borana bulls
September 2007
Twenty four Borana bulls (average weight 218 ± 6.3 kg) were randomly assigned to 4 finishing diets to study the effects of basal diets on carcass composition. Diets were: R1 (teff straw 30%, local hay 10%, haricot bean straw 10%, molasses 20%, corn grain 20% and haricot bean grain 10%), R2 (teff straw 10%, haricot bean straw 20%, maize stover 10%, molasses 15%, corn grain 25%, noug cake 10% and linseed cake 10%),...
Anopheles species abundances, composition and vectoral competence in six areas of Lagos: Nigeria
September 2007
Malaria is a problem in Nigeria and the risk exists throughout the country. Anopheles mosquitoes have been incriminated as the major malaria vectors. Vectors competence, however, differs from one species to another and from place to place. The present study reports the species abundance, composition and vectoral competence of Anopheles species in six areas of Lagos in Nigeria. The human blood index (HBI) and...
Isolation and cloning of IGF-1R gene in bovine
September 2007
Gene cloning, or molecular cloning, has several different meanings to a molecular biologist. A clone is an exact copy, or replica, of something. Molecular biologists exploit the replicative ability of cultured cells to clone genes. Recent advances in the Restriction enzymes technologies have opened up new opportunities in biotechnology and facilitate the way to isolate any gene from any source of cells. Many...
Effects of season on the quality and in vitro maturation rate of Egyptian buffalo (Bubalus bubalis) oocytes
September 2007
Recent advances in in vitro maturation, fertilization and culture technology allowed progress in an increasing the number of off springs produced from genetically superior females but this progress still has important factors affect the yielding and quality of the oocytes. It was referred that, there is a distinct similarity in season profile between an in vitro and in vivo reproductive traits. The influence of season...
Evidence of multiple preovulatory LH and FSH surges in mithun (Bos frontalis)
August 2007
The experiment was conducted on 14 postpartum mithun (Bos frontalis) cows to establish the preovulatory LH and FSH surge patterns during estrus in peripheral circulation. Blood samples from jugular vein were collected every 2 h until 72 h and on alternate days till day 22 (day 0 = day of estrus) following the day of estrus onset. Plasma progesterone (P4), LH and FSH levels were estimated. Plasma P4 profile of the...
The effects of feeding liquid acid whey in the diet of lactating dairy cows on milk production and composition
August 2007
Eighteen Holstein dairy cows averaging 141 days in milk were used in a complete randomized design to determine the effects of feeding liquid acid whey (LAW) on milk production and composition. Animals received a diet consisting of berseem clover (Trifolium alexandrinum., L), wheat straw and concentrate (Control). Treatments were control and control plus 40 liters/cow/day of LAW. Daily individual Dry Matter Intake...
Ecology of Andaman Sea: past, present and future
August 2007
The marine resources are a major source of food, a reservoir of minerals, major suppliers of oxygen, regulator of climate and also an ultimate dumping ground for the mounting burden of human waste material. Due to unchecked anthropogenic activity in recent years, the physico-chemical and biological status of the marine environments have changed significantly, which in turn resulted in the changing environmental...
