A Simulation Model Including Ovulation Rate, Potential Embryonic Viability, And Uterine Capacity To Explain Litter Size In Mice: Ii. Responses To Alternative Criteria Of Selection, E. L. De A. Ribeiro, Merlyn K. Nielsen, Kreg A. Leymaster, Gary Bennett

Department of Animal Science: Faculty Publications

Direct selection for litter size was compared with selection for ovulation rate, ova success, or uterine capacity and for indexes of ovulation rate with ova success or uterine capacity. Selection was simulated for 10 generations in a mouse population based on a model integrating ovulation rate, potential embryonic viability, and uterine capacity. Two indexes including ovulation rate (OR) and ova success (OS) were I = .291 x OR + 2.19 x OS and I = .165 x OR + .736 x OS. Heritabilities for ovulation rate and ova success, assumed in the simulation and to derive the indexes, were .25 …

Divergent Selection For Heat Loss In Mice: I. Selection Applied And Direct Response Through Fifteen Generations, Merlyn K. Nielsen, L. D. Jones, B. A. Freking, J. A. Deshazer

Department of Animal Science: Faculty Publications

Divergent selection for heat production/ loss (kcal•kg^-.75•d^-1) , measured in 9- to 11-wk-old male mice, was conducted for 15 generations. Heat loss was measured for 15 h on individual animals placed overnight in direct, gradient-layer calorimeters. Selection for high (MH) and low (ML) heat loss and unselected control (MC) occurred in each of three replicates for a total of nine unique lines. Repeatability of the heat loss measurement was .45 and the CV was 10.5%. Cumulative realized selection differentials, averaged for the three replicates, were 145.1 and -105.0 (kcal•kg^-.75•d^-1) and ranged from …

Limiting Amino Acids In Meat And Bone And Poultry By-Product Meals, M. J. Klemesrud, Terry Klopfenstein, Austin Lewis, D. H. Shain, D. Herold

Department of Animal Science: Faculty Publications

In situ, digestion, and growth studies were conducted to evaluate four meat and bone meals and six poultry by-product meals as sources of escape protein and to predict the first-limiting amino acid for growing calves. Escape protein values, determined by 12-h in situ incubation, ranged from 41.7 to 51.0% of CP for meat and bone meals; poultry by-product meals ranged from 32.0 to 39.8%. True protein digestion in the gastrointestinal tract of lambs differed among protein sources ( P < .05), ranging from 79 to 95%. In each of three growth trials, 60 steers (258 ± 24, 241 ± 23, and 230 ± 16 kg for Trials 1, 2, and 3, respectively) were supplemented with 4 of the 10 protein sources along with a urea supplement. Protein sources were fed at 30, 40, 50, and 60% of the supplemental CP, with urea supplying the remainder. Protein efficiency differed among treatments ( P < .10), ranging from .61 to 1.55. Amino acid composition was determined for each protein source, and the individual metabolizable amino acids were regressed on the protein efficiency values. Escape protein values were correlated (R² = .75) with protein efficiency but had a negative slope. Metabolizable methionine was the only amino acid moderately correlated (R …

Development Of Gilts And Boars For Efficient Reproduction, Donald G. Levis, Vernon D. Leibbrandt, Dale W. Rozeboom

Department of Animal Science: Faculty Publications

Successful introduction of replacement gilts and boars into the breeding herd is an important aspect of breeding herd efficiency. To attain herd efficiency, females must ovulate adequate numbers of viable ova, express estrus, show willingness to mate, and conceive in a regular manner. Males must produce adequate numbers of fertile spermatozoa, possess ability and show willingness to mate, and produce high-conception rates. If these qualities are properly developed, pregnancy rate and litter size will be maximized.

G97-1342 Feeding Value Of Alfalfa Hay And Alfalfa Silage, Terry L. Mader, Todd Milton, Ivan G. Rush, Bruce Anderson

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses the feeding value of alfalfa under different harvesting, storage and feeding methods, as compared to other protein sources.

In Nebraska, alfalfa is used primarily as a protein source. However, for cow-calf producers it can sometimes be an economical energy source, depending on the prevailing price of feed grains and other sources of energy.

Alfalfa is generally harvested as dry hay or as silage (65 percent moisture). Ensiling at 45 to 55 percent moisture is also common, particularly if the alfalfa is stored in an upright oxygen-limiting structure. Regardless of harvesting and storage methods, some dry matter and …

Ec97-276 Management Strategies For Pen-Mating Female Pigs, Donald G. Levis

University of Nebraska-Lincoln Extension: Historical Materials

The master control switch of a pork production enterprise is weaning day. Pork production managers have little or no control concerning when a weaned female will cycle or how long she will be in estrus after weaning. When females are pen-mated, the producer needs to use management procedures to prevent an excessive number of estrous females from expressing the standing response at the same time, try to manage estrous females so that they are bred at the proper time, try to manage boars so they maintain an adequate level of fertility, evaluate boars for level of sexual behavior before and …

Successfully introducing replacement gilts into the breeding herd is an important aspect of breeding herd efficiency. To attain herd efficiency, females must ovulate adequate numbers of viable ova, express estrus, show willingness to mate and conceive in a regular manner. If these qualities are properly developed, pregnancy rate and litter size will be maximized. A gilt development and management program needs to be designed for gilts from birth to farrowing their first litter.

Male Love And Islamic Law In Arab Spain, Louis Crompton

Department of English: Faculty Publications

A unique flowering of homoerotic poetry took place in Iberia after the Arab conquest in 71 L The efflorescence there repeated a phenomenon of the Islamic world generally, paralleling the erotic lyrics of Iraq, Persia, Afghanistan, Mughal India, Turkey, and the North African states of Egypt, Tunis, and Morocco. The anthologies of medieval Islamic poetry, whether compiled in Baghdad, Damascus, Isfahan, Delhi, Kabul, Istanbul, Cairo, Kairouan, or Fez reveal, with astonishing consistency over a period of a millennium, the same strain of passionate homoeroticism we find in love poems from Cordoba, Seville, and Granada.

G97-1334 Estimating Manure Nutrients From Livestock And Poultry, Richard K. Koelsch, Charles A. Shapiro

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses a procedure for estimating the quantity of nutrients in livestock manure. When managed properly, nutrients in livestock manure can be a valuable resource. When managed improperly, however, these same nutrients become a potential environmental pollutant. Accurate crediting of manure nutrients within a total crop nutrient program is fundamental to utilizing manure as a resource. This NebGuide will help producers estimate the total manure nutrients (N, P and K) produced by their livestock and show how to adjust for losses for various storage and handling situations.

Ec97-277 Minerals And Vitamins For Beef Cows, Richard J. Rasby, Dennis R. Brink, Ivan G. Rush, Don C. Adams

University of Nebraska-Lincoln Extension: Historical Materials

Introduction

Mineral supplementation programs range from elaborate, cafeteria-style delivery systems to simple white salt blocks put out periodically by producers. The reason for this diversity: little applicable research available for producers to evaluate mineral supplement programs. There is a need of information regarding mineral composition and availability from various feedstuffs (i.e. pasture grasses, hays, by-products, etc.) and the possible interactions between minerals in the digestive system. Also lacking is a data base to establish accurate estimates of mineral requirements for beef cattle.

Assessing the consequence of mineral deficiencies in the cow, calf or stocker animal is difficult because slightly lowered …
