We hypothesized that adaptation of heat production in the realimented cow would occur over an extended period, and the length of time would be influenced by the level of feed. Our objectives were to quantify the changes in heat production of cows after feed restriction and to quantify the effect of level of realimentation on the dynamics of heat production in lightweight cows. Forty 4-yr-old no...

. 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...

Three experiments were conducted to evaluate the response of supplementing primiparous heifers based on the metabolizable protein (MP) system during pregnancy and lactation. In Exp. 1, 12 pregnant, March-calving heifers (432 +/- 10 kg) grazing Sandhills range were randomly allotted to one of two treatments: supplementation based on either the MP system (MPR) or the CP system (CPR). Supplements ...

Blood serum concentration of IGF-I was analyzed to determine its relationship with individual postweaning feed efficiency (gain/feed) of 36 crossbred steer calves fed at three levels of feed intake (n = 12 at each level). Diets consisted of a corn silage-based growing diet for 84 d followed by a 91% concentrate finishing diet for 56 d. Dietary intake levels were at 80, 90, or 100% of ad libitum...

BACKGROUND Feeding alfalfa hay is often recommended for its buffering components, like protein and calcium, to prevent lesions of the gastric mucosa in horses. Until now, there has been no information regarding the influence of alfalfa particle size on the gastric mucosa. The aim of this study was to investigate the effects of feeding two alfalfa preparations with different particle sizes (alfa...

This study was carried out at Alkhurmah Governorate; Taif, Kingdom of Saudi Arabia (KSA).Thirty weaned males of Najdi sheep aged between 3-4 months with average body weight 22.87±.0.18 kg were used for study. Animals were allotted to three comparable groups (10 lambs/each), the first group served as control (fed ration composed of 60% concentrate feed mixture (CFM) plus 40 % alfalfa hay) while ...

Treponema saccharophilum was isolated in the early decades and described as highly preferred to utilize pectin for growth. Typically, alfalfa hay contains 10–15% pectin as a component of the cell wall matrix, whereas grass or corn stover has pectin content less than 5%. The objective of this study was to develop a set of PCR primers targeting the 16S rRNA gene of T. saccharophilum and to assess...
