| Trials on the seabass weaning in atlantic marshes (Roux, 1993), have shown that the use of frozen prey improved this step and reduced his resulting stress. During the present study, which must confirmed these preliminary results, three alimentary sequences were tested. 1) natural zooplankton, weaning pellets, as control, 2) natural zooplankton, inert artemia (intensively produced), weaning pellets, 3) natural zooplankton, natural frozen zooplankton (harvested), weaning pellets. The achieved results show that weaning with intermediary phases (sequences 2 or 3) yield best results. Furthermore the phase with artemia yields, systematically, better results than with harvested zooplankton ; then artemia seems a excellent substitute food representing a... |

| In this study, three microdiets were tested on weaning of Florida pompano larvae: Otohime, Gemma and a reference diet LR803. The experimental system was stocked with 11-day-old larvae, which were co-fed micro-diets and live food from 11 dph to 17 dph then micro-diets only until 28 dph. Survival from 11 dph to 28 dph was similar for all treatments, with an average of 33%. At the end of the trial, the Gemma larvae were significantly longer and heavier than larvae fed the other diets. Significant differences were observed in fatty acid composition of the diets and larvae between treatments. The Gemma larvae incorporated the lowest amount of eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA) and arachidonic acid (ARA). However, they had the highest... |

| An exclusively milk formula diet stunted the growth of mice immediately following weaning. Milk-fed mice displayed a low-frequency profile of exploratory behavior, while pellet-fed mice showed high-frequency exploration. In contrast to exploratory behavior, feeding behavior did not differ significantly between milk- and pellet-fed mice. Despite showing low-frequency exploratory behavior, mice on an exclusively milk formula diet showed no difference in behavioral activities analyzed by an automatic hole-board apparatus compared to pellet-fed mice. These results suggest that the growth stunt caused by an exclusively milk formula diet retards the acquisition of active exploratory behavior without affecting the emotional state of mice. |

| Post-weaning mice fed exclusively milk display low-frequency exploratory behavior [Ishii, T., Itou, T., and Nishimura, M. (2005) Life Sci. 78, 174-179] compared to mice fed a food pellet diet. This low-frequency exploratory behavior switched to high-frequency exploration after a switch from exclusively milk formula to a food pellet diet. Acquisition of the high-frequency exploratory behavior was irreversible. Recently, we demonstrated that the mesencephalic trigeminal nucleus (Me5) is involved in the control of feeding and exploratory behavior in mice without modulating the emotional state [Ishii, T., Furuoka, H., Itou, T., Kitamura, N., and Nishimura, M. (2005) Brain Res. 1048, 80-86]. We therefore investigated whether the Me5 is involved in acquisition... |

| The objective of this work was to evaluate the effect of insulin alone or in association with equine chorionic gonadotropin (eCG) on the fertility of postpartum beef cows subjected to synchronization. A total of 340 cows was subjected to fixed time artificial insemination. In the trial 1, the cows were subjected to temporary weaning (TW), while in the trial 2 the same protocol was tested without TW. The addition of an insulin injection to a progesterone/eCG-based protocol without TW increased the pregnancy rate of beef cows with body condition score (BCS) equal to or lower than 2.5. Insulin had no effect on cows submitted to TW or with BCS equal to or higher than 3.0. |

| Abstract: The objective of this work was to evaluate the effects of increasing the contents of total solids (TS) in whole milk, by adding increasing amounts of milk replacer powder, on the behavior of dairy heifers. Holstein-Gyr crossbred heifers (n = 60) were distributed in four treatments: 13.5, 16.1, 18.2, and 20.4% TS. From 5 to 55 days of age, heifers received 6 L per day of liquid feed, which was reduced by half from 56 to 59 days. Heifers were weaned at 60 days of age and monitored until 90 days, and their behavior was evaluated weekly. During gradual weaning and after weaning, heifer behavior was recorded 1 hour before and 1 hour after liquid feed was offered, and, during weaning, it was evaluated by the scan method. Heifers fed liquid feed... |

| The NAHMS Beef '97 Study was designed to provide both participants and the industry with information on the nation's cow-calf population for education and research. The USDA's National Agricultural Statistics Service (NASS) collaborated with NAHMS to select a statistically-valid sample yielding 2,713 producers from 23 states. The 23-state target population represented 85.7 percent of U.S. beef cows on January 1, 1997, and 77.6 percent of U.S. beef operations. Federal and state Veterinary Medical Officers (VMO's) and Animal Health Technicians (AHT's) collected data for this report on-farm from March 3, 1996, through May 23, 1997, from 1,190 operations that had five or more beef cows on January 1, 1997.

| Section 1 of this report shows demographic changes of the U.S. beef cow-calf industry from a historical perspective from data provided by the National Agricultural Statistics Service (NASS) and Census of Agriculture. Results of two NAHMS national studies in Section II complete the overview of change in the U.S. beef cow-calf industry during the 5-year period from 1993 to 1997. NAHMS, CHAPA Phase I included data collected from 2,539 cow-calf operations in the 48 continental states via telephone during the fall of 1992. Subsequent data collection was done on operations in 18 states and from producers with five or more beef cows and 50 percent or more of their calf crop born between January 1 and June 30 (spring calving) The 18 states represented 70... |

| The NAHMS Dairy '96 Study was designed to provide both participants and the industry with information on the nation's dairy animal population for education and research. This report contains demographic changes of the U.S. and world dairy industry from a historical perspective from data provided by the National Agricultural Statistics Service (NASS), Census of Agriculture, and Foreign Agriculture Service. Results of two NAHMS national studies overview changes in the U.S. dairy industry in the 5-year period of 1991 to 1996. The 1991 National Dairy Heifer Evaluation Project included herds of 30 or more milk cows and heifer-rearing operations in 28 states representing 83 percent of U.S. milk cows. NAHMS Dairy '96 described dairy production for operations... |

| The National Animal Health Monitoring System (NAHMS) Beef '97 Study collected data on the marketing practices of 2,713 beef cow-calf producers representing 85.7% of all beef cows as of January 1, 1997, in 23 leading cow-calf states. Of the operations included in the study, 67.4% sold steer calves, and 52.1% sold heifer calves for slaughter in the year preceding the study. By number of operations, auction was the most common method of selling steers (84.9% of operations) and private treaty was the second most popular marketing method (10.4% of operations). By number of steers sold, private treaty was the most common marketing method. For operations selling either steer or heifer calves, smaller operations were more likely to use auctions as a marketing... |

| As part of the National Animal Health Monitoring System (NAHMS ), USDA:APHIS:Veterinary Services conducted a national study of beef production, the Beef Cow/Calf Health and Productivity Audit (CHAPA). This study was designed to provide both participants and the industry with information on cow/calf health, productivity, and management practices. Data for Part 1: Beef Cow/Calf Herd Management Practices in the United States, were collected from beef producers September 29 through October 9, 1992. The National Agricultural Statistics Service (NASS) collaborated with VS to select a statistically designed producer sample that represented all U.S. cow/calf operations in the 48 continental United States. Eighty-one percent of operations had commercial cattle... |
