Two experiments were conducted to evaluate the effects of a winter feeding strategy on the performance, lactation, reproduction, and feed costs of springcalving, lactating beef cows. In Exp. 1, Angus (n = 66) and Simmental (n = 70) cows were allotted to 1 of 4 treatments: 1) distillers dried grains with solubles (DDGS) and free-choice corn residue bales; 2) corn bran and DDGS and freechoice cor...

introduction using agro-industrial by-products in ruminants feeding could help in semi arid climate condition throughout the year. raisin by-product is produced in huge magnitude in malayer city, hamedan province. local different raisin by-products which produced during machinery cleaning and sorting of sun dried treated grapevine cluster (vitisvinifera l. cv. sultana), are as:1) some outer lay...

BACKGROUND Molecular structures in feed protein influence its digestive behavior, availability and utilization. From a nutritive point of view, stage of maturity and cutting time are important factors affecting nutrient profiles and availability of alfalfa (Medicago sativa L.) hay in ruminants. The objectives of this study were to determine protein molecular structures by Fourier transform infr...

The objective of this study was to evaluate the effects of weaning age on dry matter intake (DMI), average daily gain (ADG), feed efficiency (FE), feed cost (FC) and benefit index (BI) of Holstein calves reared under organic farming system. Thirty two Holstein calves were divided into two treatments: early weaning (EW) vs. late weaning (LW). Calves in the both groups were provided with whole mi...

A comparison of conserving timothy/meadow fescue/meadow grass as silage or hay was conducted with Finnish Landrace ewes. Intake of hay (H), silage (S) and hay/silage (HS), and the performance of 30 Finnish Landrace ewes carrying twins, triplets and quadruplets and suckling either twin or triplet lambs was measured during the last 8 weeks of pregnancy and during the first 6 weeks of lactation. T...

Plant essential plant oils (EO) are volatile aromatic compounds with antimicrobial activity that can alter ruminal fermentation when used as dietary supplements. A feeding trial was conducted to determine the effects of dietary supplementation of periparturient and early lactation dairy cows with a specific mixture of EO. Forty multiparous Holstein cows were randomly assigned to either control ...

In large-type goats that were fed on dry forage twice daily, dry forage intake was markedly suppressed after 40 min of feeding had elapsed. The objective of this study was to clarify whether or not increases in plasma osmolality and subsequent thirst sensations produced by dry forage feeding suppress dry forage intake. Eight large-type male esophagealand ruminal-fistulated goats (crossbred Japa...

In this study were used 40 newborn singleton Akkaraman and Merino lambs with 4 trial groups consisting of selected 10 homogeneous according to race gender. Trial was carried out 100 days, covering 5 feeding periods 21-day from the birth lambs. The fed lamb starter feed for first two months, then grower ad-libitum 250 g/day/head dry alfalfa hay. At end study; it determined that lowest total anti...

This study was carried out to evaluate the effects of feeding ensiled mixed tomato and apple pomace (EMTAP) on blood metabolites and chewing behavior of dairy cow. Six multiparous Holstein dairy cows in mid lactation were used in 3×3 Latin square design and fed alfalfa hay plus concentrate mixture with three levels replacement with EMTAP (0, 15, 30%) during 63 days. Results showed that, differe...
