This paper reviews the literature comparing growth performance, carcass, and meat quality data between barrows and boars. Compared with barrows, boars have reduced feed intake, improved feed efficiency, less backfat, higher nitrogen retention, and leaner carcasses. Growth rate of boars will be higher than that of barrows if adequate dietary amino acids are supplied. The improved growth performa...
20 one-month-old sanjabi suckling lambs (ten males and ten females with initial liveweight of 13.4 ± 1.3 and 11.6 ± 0.9, respectively) were used to assess the effect of ad libitum creep mixture on dry mater intake, live weight gain and carcass characteristics. the lambs were blocked within sex according to their live weight and randomly allocated to one of two treatments, control (free suckling...
126 abstract: in this research we studied the effects of cyclic hydration and dehydration of cysts of artemia urmiana and artemia parthenogenetica on the hatching percentage, survival and growth. the experiment was carried out in 3 treatments (1-3 hydration/dehydration cycles) with 3 replicates for each treatment. later effects of cold preservation at -20°c during three time periods were ...
This experiment was carried out to study the effect of the inclusion of a yeast culture in the diet of feeder dairy calves on their growth and carcass characteristics. Thirty male Friesian calves were randomly allocated to two groups of 15 each (treatment and control). The calves were fed a total mixed ration for a period of 294 days and then slaughtered to obtain carcass measurements. The yeas...
introduction acetic acid bacteria are large group of obligate aerobic gram negative bacteria with the ability to oxidize ethanol to acetic acid (1). they are widely distributed in natural habitats and classified in family acetobacteraceae. members of this family are useful in industrial production of vinegar(2). acetic acid bacteria (aab) can use substrates as glucose, ethanol, lactate or glyc...

Two experiments were conducted to evaluate the effect of feeding legume hay (alfalfa; Medicago sativa L.) or mixed-grass hay on ADG and carcass characteristics of growing goats. In Experiment 1, 24 Spanish kids, equally representing female, intact male and wether goats, were pen-fed ad libitum either chopped alfalfa (16.8 percent CP) or mixed grass hay (9.4 percent CP) (3 pens/diet) and a corn/...
Methionine is the first limiting amino acid in poultry which has a primary role in stimulating protein synthesis and growth. This study was designed to investigate the effect of dietary intake of different levels of DL-methionine on hatchability, carcass characteristics, and blood parameters of day-old Ross 308 broiler chicks. For this purpose, 240 fertile broiler breeder eggs were used in a co...
Brahman cattle are important in tropical regions due to their ability to tolerate excessive heat and parasites. However, Brahman cattle exhibit lower carcass quality characteristics when compared to Bos taurus breeds. The objective of this study was to evaluate potential associations between single nucleotide polymorphisms (SNPs) in six candidate genes for carcass quality and composition traits...
