New Zealand dairy farmers use a number of performance indicators to describe their systems. Most of the performance indicators are scaled to a unit of feed or a proxy that relates a cow to a unit of feed, such as stocking rate or kilograms of live weight per tonne of feed. Genetic improvement of dairy cows can contribute to increasing the net income per unit of feed consumed. The current econom...

This reseacrh aims to find out the effect of probiotic administration Bacillus subtilis BN Strain on shell thickness, white index and chicken yolk index. research used 38-week-old layer laying hens as many 24 heads, randomized into four treatments with eight replays. Treatment consists P0 without addition probiotics, P1 0.005 grams / kg feed, P2 0.01 feed P3 0.02 feed. Based analysis statistica...

A model of a mixed-mode nutrient recovery reactor is developed for a urine feed, incorporating complex solution thermodynamics, dynamic conservation relations and a power-law kinetic expression for crystal growth from seed crystals. Simulations at nominal operating conditions predict phosphorus recoveries greater than 99%, based on existing process kinetic parameters and operating conditions em...

one hundred forty-four 26-wk-old white hy-line layers (w-36) were fed commercial diets containing 0, 1.5, 3 and 5% surplus date for three period of 28 days each to study the effects of dietary surplus date on hen performance (egg production, egg weight, egg mass, feed intake, feed conversion ratio ‘fcr’ and body weight gain) and egg quality parameters (haugh unit score, yolk colour index, yolk ...

Feed costs typically represent more than 50% of total costs of producing milk on a dairy farm. Feed cost savings, even a few dollars per ton, add up to significant savings over a year on a large dairy. For many dairies, a ration-balancing software program that uses linear programming techniques can be used to determine the opportunity cost or price of including a new feed in a ration. However, ...

Chhana cake, locally termed chhana podo, is a baked traditional dairy product of India. The present study was undertaken for optimization of process parameters pertaining to production of chhana podo. Independent variables, namely, moisture content of feed-mix: 52.5 62.5% (wb), baking temperature: 60 180°C, baking time: 1 9 h and height of feed-mix: 1 5 cm were selected heuristically and their ...

The objective of this study was to compare fattening performance, carcass traits, and egg quality of Japanese quails with different feather colors (white, dark brown, golden, and wild-type). In the study, 360 one-day-old quail chicks with 4 different feather colors were used as animal material. Quails were fed ad libitum for 42 days to determine fattening performance and carcass traits. To dete...

Using distillers dried grains with solubles (DDGS) as a feed ingredient in poultry nutrition has lately been increased. This study was conducted to evaluate the effect of adding different dietary levels of DDGS on the productive performance of broiler chicks from 1 to 35 d of age. Two hundred forty one-d-old broiler chicks were randomly distributed among 3 treatment groups with eight replicates...
