To determine the value of pre-pubertal plan of nutrition on reproductive performance, hormonal concentrations and milk production in ewe lambs, a total of 40 clinically health Kurdish female lambs (30±8.6 d and weighing 10.2±3.4 kg) were randomly allocated to one of two experimental diets in pre-weaning period: high quality diet (HQD) (HQD, 2.50 Mcal ME/kg dry matter (DM) and 148 g CP/kg DM) or...

The effects of dietary protein content and feeding level on the utilization of metabolizable energy (ME) and on the rates of gain, protein and fat deposition have been studied in seventy-two Iberian pigs growing from 15 to 50 kg body weight (BW) by means of comparative slaughter experiments. The animals were fed on six diets providing 223, 192, 175, 156, 129 and 101 g crude ideal protein ( CP)/...

Grass silages (n = 136) were selected from commercial farms across Northern Ireland according to their pH, ammonia nitrogen, DM, and predicted ME concentration. Each silage was offered to four sheep as a sole feed at maintenance feeding level to determine nutrient digestibility and urinary energy output. Dry matter concentration was determined as alcohol-corrected toluene DM and was subsequentl...

Feed is an absolute necessity that must be guaranteed in the maintenance of ruminants but its availability always a problem during dry season so fresh forage difficult to obtain and only agricultural waste form straw available. One widely used by farmers, especially Lombok region, corn straw. This research aims evaluate nutritional content has been ammoniated using urea. study urea for ammoniat...

1. The experiment was designed to investigate the effect of protein level in diets on apparent protein digestibility (AD), true protein digestibility (TD), biological value (BV), net protein utilization (NPU) and energy digestibility (DE) in rats. The design involved fourteen dietary treatments in which a combination of wheat bran and meat-and-bone meal (1:1, w/w dry matter (DM) basis) was the ...

to determine the chemical compositions, minerals and in vitro digestibility lathyrus sativusstraw during three years in shahrekord, kohrang and lordegan climates in chaharmahal & bakhtiari. this was one of the important legume straws that farmers used in ruminant winter diets in south west of iran. this legume straw gathered of different climates for three years. all samples were chemically ana...

Dietary supplementation with conventional linted cottonseed hulls (LCSH) is a common practice in livestock production all over the world. However, supplementation with mechanically delinted cottonseed hulls (DCSH) and cottonseed linter residue (CLR) is uncommon. Cottonseed by-products, including LCSH, DCSH and CLR, were assessed by chemical analysis, an in situ nylon bag technique, an in vitro ...
