Seventy-two crossbred pigs (average initial weight 6 kg) were used to study the effect of L. acidopbilus (lactic acid-producing bacteria common in probiotics) in starter diets on gain, feed conversion, fecal lactobacillus and coli-form counts, hematology and serum proteins. The nonmedicated experimental diets were corn-soybean meal (18% crude protein) diets with two levels of lactose (0 and 10%...

The objectives of this study were to estimate genetic parameters and sire breeding values for average daily gain (ADG) and carcass traits using sire-maternal grandsire model with REML approach, sire model with REML approach, sire model without relationships among sires and with REML and ANOVA approach, and to investigate advantages and disadvantages of these methods. Data were collected from 42...

A ‘resolution’ of the interior singularity of the spherically symmetric Schwarzschild solution of the Einstein equations for the gravitational field of a point-particle is carried out entirely and solely by finitistic and algebraic means. To this end, the background differential spacetime manifold and, in extenso, Calculus-free purely algebraic (:sheaf-theoretic) conceptual and technical machin...

The study objective was to compare serum cortisol as an acute stress measure, chute exit velocity as a behavioral measure, and ADG as an indicator of performance and well-being after castration, dehorning, or concurrent castration/dehorning of calves when performed in parallel and in series. Intact male Holstein calves, 3 to 4 mo, underwent sham handling before 2 procedures performed in series ...

Two experiments utilizing a total of 530 pigs were conducted to evaluate the effects of commercial enzymes in diets containing dried distillers grains with solubles (DDGS) on nursery pig growth performance. In Exp. 1, 180 pigs (initially 19.9 lb) were used in a 27-d growth trial to compare the effects of Easyzyme, Hemicell-W, and Porzyme in diets containing 30% DDGS on weanling pig performance....

One hundred forty-four finishing pigs were used to determine the influence of added dietary niacin on their growth performance and meat quality. Gilts grew slower, ate less, and were more efficient than barrows for the entire growth performance period. Increasing dietary niacin levels to 25 g/ton increased ADG in gilts for the first 25 days, but decreased ADG for barrows. No other interactions ...

A finishing trial evaluated the effects of feeding different levels of soyhulls with modified distillers grains plus solubles (MDGS) on feedlot cattle performance. Soyhull inclusion level was 0, 12.5, 25, or 37.5% of diet DM. As soyhulls replaced dry rolled corn (DRC), ADG decreased linearly (4.22 vs 3.48) and F:G increased linearly in response to increasing levels of soyhulls. When comparing t...

Recycling of different products and waste materials plays a crucial role in circular economy, where the anaerobic digestion (AD) constitutes an important pillar since it reuses nutrients form organic fertilizers. Knowledge about digestate compost microbial community structure its variations over time is important. The aim current study was to investigate microbiome slurry cow produced on farm (...

A total of 360 weaned pigs (DNA 241 × 600: initially 12.6 lb) were used to evaluate the effects previous sow feed flavoring treatment (control vs. flavor) and nursery diets formulated with or without a flavor on growth performance in 38-d trial. Pigs at approximately 19 d from sows fed 0.05% (Krave AP, Adisseo, Alpharetta, GA). placed pens (5 6 per pen) within randomly assigned 1 2 dietary trea...

Voluntary Feed Intake (VFI) and Average Daily Gain (ADG) of three rabbit breeds fed on pigeon pea (PP), cowpea (CoP) soybean (SB) as sources protein for growing rabbits were determined. Flemish Giant (FG), California Black (CB) New Zealand White (NZW)) (Glycine max), (Cajunus cajan) (Vigna unguiculata) in the ration. Eighteen weaned at six weeks age used each breed (a total 54 rabbits) out whic...
