Yang, Han - - 2009
This study was carried out to compare the growth performance and quality properties of pork from finishing pigs fed different levels of betaine. A total 120 female pigs (LandracexYorkshirexDuroc) were fed either a control commercial diet or the control diet supplemented with 2, 4 and 6% betaine for 31 days. ...

The present study was conducted to evaluate the effect of chilled drinking water on the productivity of laying hens under constant high ambient temperature. A total of seventy-two, 123-day-old Hy-line brown layers was divided into two equal groups. The first group (UDWG) was given unchilled water (23.0[+ or -]2.5[degrees]C) as ...

A 21- to 42-day feeding study was conducted in Ross male broilers to evaluate the use of dried bakery product (DBP) and the influence of adding fat at different points in the manufacturing process. Six dietary treatments were formulated using a factorial arrangement (3x2 design) with three levels of fat ...

L-carnitine promotes mitochondrial [alpha]-oxidation of long chain fatty acids and their subsequent transport across the inner mitochondrial membrane. Although the role of L-carnitine in fatty acid metabolism has been extensively studied, its role in live performance and carcass responses of commercial broilers is less understood. The objective of this research ...

The objective of this study was to investigate antimicrobial activity, during the storage period, of animal feed and any effects on in vitro rumen digestion by supplementing different levels (5.55, 11.1, and 22.2 g/kg) of freeze dried citrus peel (FDCP) to the feed compared to untreated feed and feed treated ...
Kamalzadeh, A. - - 2009
Ninety six intact male sheep (12 months old with mean live weight of about 35 kg) were used to assess the effects of restricted feeding on intake, digestion, nitrogen balance and metabolizable energy (ME). The animals were selected from two known Iranian small and large body size breeds: 48 Sangsari ...
Sun, T. - - 2009
Metabolizable protein (MP) supply and amino acid balance in the intestine were manipulated through selection of highly digestible rumen-undegradable protein (RUP) sources and protected methionine (Met) supplementation. Four ruminally-cannulated, multiparous Holstein cows averaging 193[+ or -]13 days in milk were used in a 4x4 Latin square design to assess N ...
Khezri, A. - - 2009
Four multiparous lactating Holstein cows fitted with rumen cannulae were fed diets varying in the amount and source of rumen-degradable carbohydrates (starch vs. sucrose) to examine their effects on rumen fermentation, nitrogen metabolism and lactation performance. A 4x4 Latin square with four diets and four periods of 28 days each ...
Viswanathan, T.V. - - 2009
Two metabolism trials were conducted with 24 wether lambs to investigate the effects of feeding crab meal and other protein supplements on N utilization, digestibility and Ca and P balance in sheep. The lambs (avg. BW, 25 kg) were randomly allotted to eight diets in each of two trials. The ...
Chiu, C.H. - - 2009
The corpus luteum (CL) is a transient endocrine gland that produces progesterone, a product required for the establishment and maintenance of pregnancy. In the absence of pregnancy, the production of progesterone in the CL decreases and the structure itself regresses in size. The life span and function of the CL ...

An experiment was conducted to investigate the effect of Butylated Hydroxy Anisole (BHA), Butylated Hydroxy Toluene (BHT), Pentoxifylline (PTX), Theophylline (TPY) and Theobromine (TBR) on cold protection ability of Murrah buffalo semen at room (22-25[degrees]C) and refrigerated temperature (4-7[degrees]C). Each semen sample was divided into six parts of equal volume ...
Zhang, Liuping - - 2009
The objective of this work was to study the direct effects of daidzein on steroidogenesis in cultured mouse Leydig cells. Adult mouse Leydig cells were purified by Percoll gradient centrifugation, and the cell purity was determined using a 3[beta]hydroxysteroid dehydrogenase (3[beta]-HSD) staining method. The purified Leydig cells were exposed to ...
Sheikhloo, M. - - 2009
This study was aimed at a genetic evaluation of Iranian Holstein cattle for milk and fat yields and calculating daughter yield deviation (DYD) of bulls. The data file that was used in this research included 367,943 first three lactation records of 186,064 Holstein cows which calved between 1983 and 2006 ...
Wynn, P.C. - - 2009
Provision of an optimal environment for the calf is critical to establishing the patterns of growth and development essential to allow the heifer to express its genetic potential for milk output and reproductive capacity during its productive life. Maternal nutrition during gestation is now recognised as a key to genetic ...
Hoque, M.A. - - 2009
The feed resource for animals is a major cost determinant for profitability in livestock production enterprises, and thus any effort at improving the efficiency of feed use will help to reduce feed cost. Feed conversion ratio, expressed as feed inputs per unit output, is a traditional measure of efficiency that ...

Rusa deer are the only viable commercial tropical deer species for farming in the tropics because of their hardiness, adaptability and prolific characteristics. Twelve entire rusa stags were slaughtered according to halal procedure and used for carcass evaluation and cutability studies. Three carcass categories; large (46 to 55 kg), medium ...
