Data in 144 successfully weaned Hyla rabbit kits consisting of 70 Hyla purebred and 74 crossbred Hyla rabbits were evaluated for postweaning growth performance at different ages (8, 10 and 12 weeks). Breed and sex effect differ significantly (P<0.05) at different ages studied. Crossbred male Hyla rabbits had the highest weight of 1314.57 g and 1771.52 g at 8 and 10 weeks, while the highest valu...

introduction as pregnancy progresses, nutrient requirements of fetus and thereby ewe increases and some changes in the levels of blood metabolites including glucose, cholesterol and total protein may occur. during gestation, maternal tissues contribute to supplying energy that required for fetus resulting in changes of ewe blood metabolites; however other factors such as breed, age, feeding typ...

Data from two purebred swine lines A (n = 6,022) and B (n = 24,170), and their reciprocal, cross C (n = 6,135), were used to examine gains in reliability of combined purebred and crossbred evaluation over conventional within-line evaluations using crossbred and pureline models. Random effects in the pureline model included additive, parental dominance, and litter. In the crossbred model, effect...

The article presents the results of studies indicators live weight and internal organs purebred Khalkha crossbreed Khalkha-Suffolk rams, depending on method their fattening. Experimental were conducted in Selenga aimak Mongolia laboratories Mongolian University Natural Sciences. According to research, it was revealed that rams inferior terms at birth age 8 months. When fed with rapeseed cake, h...

The objective was to determine the effect of forage quality on apparent total tract digestibility and ruminal fermentation in cattle versus sheep. Five yearling English crossbred (Hereford × Angus) steers (440.4 ± 35.6 kg of initial BW) and 5 yearling whiteface (Rambouillet × Columbia × Debouillet) wethers (44.4 ± 4.6 kg of initial BW), each fitted with a ruminal cannula, were randomly assigned...

AIM To compare the seminal attributes of neat, pre-freeze (at equilibration), and post-freeze (24 h after freezing) semen in pure and crossbred Jersey bulls. MATERIALS AND METHODS Total 36 ejaculates (3 ejaculates from each bull) were collected from 6 pure Jersey and 6 crossbred Jersey bulls and evaluated for various seminal attributes during neat, pre-freeze, and post-freeze semen. RESULTS...

A group of crossbred Dorset or Finnish Landrace ewes maintained under a synthetic light regimen (Light Treatment, 4 mo long days - 16 h light, 4 mo short days - 8 h light) and exposed to rams every 8 mo (January 1, September 1, May 1) was compared for lamb production over a period of 4.5 yr with two other comparable groups under natural daylight conditions, one exposed to rams once a year in th...

The present study was conducted to quantify and compare TLR2 (toll-like receptor 2) activity in monocyte-derived macrophages of zebu (Tharparkar) and crossbred (Holstein-Friesian × Jersey × Brown Swiss × Hariana) cattle. The cells were either induced with Pam3CSK4 or kept as control. The TLR2 activity was quantified in terms of IκB-α inhibitory subunit (NFKBIA) messenger RNA (mRNA) copies...

Because of low energy reserves at birth, piglets are dependent on the sow’s milk for survival. Breed differences can influence milk composition. The objective of this study was to examine litter characteristics, milk composition including calcium and the water holding capacity of casein, solvation, between the highly prolific Meishan breed and lean crossbred pigs. Samples were collected by hand...
