Effect of adding tallow on some production performance of Awassi ewe lambs

Abstract

This experiment was conducted in animal felid/ University of Baghdad/ College of Agriculture/ Animal production from 9/11/2016 until 9/1/2017. Twelve growing Awassi ewes lambs weighted 29.13 ±1.50 kg and 8-10 month old were used in this study, the lambs were divided into three individual groups (4 animals/ group) receive the dietary treatments contain 0.2 and 4% tallow, animals were fed concentrate at 2.5% of body weight, Alfalfa hay was given ad libitum basis as the roughage, The results found that: No significant difference between groups in total and daily concentrate, roughage and total feed intake, However, final body weight not affected by the experimental diets, total and daily weight gain had higher values (p<0.05) in diets containing 2 and 4% tallow, feed conversion efficiency improved significantly (P<0.05) in 4% tallow diet compared to other groups. It can be concluded that added tallow to sheep diets improved some productive performance such as total and daily weight gain, feed conversion efficiency. Excess animal fats from human consumption can be used as an energy source in ruminants feeds. Thus benefiting from excess animal fats from human consumption as a source of energy in ruminants' rations.

Effect of Type of Vegetable Oil and Vitamin C on Some Productive Qualities of Broiler Breeders

“…The food conversion factor was significant in all treatments compared to the control while adding vitamin C to the flax oil treatment and the palm oil treatment led to a significant improvement in the food conversion factor between them compared to the flax oil treatment and the palm oil treatment at the probability level (P ≥0.05). The above results agreed with the results of [31], which showed a significant improvement in the feed conversion factor by adding flax oil to laying hens' diets compared to the control group. The results agreed with the researcher [25], showing that the best feed conversion factor for laying hens was He fed a mixture of 3% soybean and flax oil.…”

Effect of Addition of Different Concentrations of Bentonite to the Ration on Concentration of Blood Minerals and Ruminal Fluid Traits of Awassi Lambs

“…Ruminant animals having the ability to respond to different food additives the leads to improvement of animal performance through the improvement of efficiency of different food elements and prevents the danger resulted from affection with metabolic diseases (3,4). The food additives may be nutritional like addition of animal fats (5) or non-nutritional additives like Bentonite salts which in organic materials gaseous clays originated from valconies and having a great ability of increase absorption and ions exchange (6). Bentonite clay have a white green light colour or blue, when exposed to the air or sun light becomes deep blue or red or light brown (7).…”
