“…In the present study, dietary CSM concentrations had no effects on meat quality, including color, pH, expressible moisture, and shear force value. Our results were different from those of Abdallh et al ( 2018 ), who found that in fresh broiler meat (day 1) or during storage (day 1 to day 8), meat color (especially L* and a*) was increased by CSM inclusion. The reason for the difference between their study and ours may be the difference in the bird breeds.…”

Cottonseed meal ( CSM ), which is an unconventional protein material with abundant sources, high protein content, and a relatively cheap price, can be used in poultry diets. The aim of this study was to investigate the effects of CSM on slaughter performance, meat quality and meat chemical composition in Jiangnan White goslings. A total of 300 healthy 28-day-old male goslings were randomly divided into 5 treatments, with 6 pens containing 10 geese each. Five isonitrogenous and isocaloric experimental diets were formulated such that 0% (a corn-soybean meal basal diet, control), 25% (CSM 25 ), 50% (CSM 50 ), 75% (CSM 75 ), and 100% (CSM 100 ) protein from soybean meal was replaced with CSM (corresponding to 0, 6.73, 13.46, 20.18, and 26.91% CSM in the feed, respectively). On day 70, 1 goose from each pen (6 geese per treatment) was randomly selected and killed to measure the slaughter performance, meat quality, and the meat amino acid ( AA ) and fatty acid ( FA ) compositions. The results showed that dietary CSM did not affect the slaughter performance or meat quality of geese ( P > 0.05). The fat content of breast muscle in the CSM 100 group was higher than that in the control group ( P < 0.05). A concentration of 13.46% or more dietary CSM increased the threonine content but decreased the cysteine content, and 20.18% dietary CSM also decreased the valine content ( P < 0.05). Dietary CSM concentration had no effect on the content of total saturated FAs (SFAs, P > 0.05), but 20.18 and 26.91% dietary CSM increased the content of total monounsaturated FAs and decreased the content of total polyunsaturated FAs (PUFAs) and PUFA/SFA in the breast muscle of geese ( P < 0.05). In conclusion, dietary CSM did not affect the slaughter performance or meat quality of geese, but the replacement of soybean meal with CSM in whole or high proportion altered the composition of AAs and FAs in breast muscle.

An experiment was conducted to study the effect of dietary enzyme supplementation (E) on the performance of KUB chickens fed different nutrient densities (ND). Diets with three densities: 70.7 g crude protein/Mcal or high (H), 66.1 g crude protein/Mcal or medium (M), and 59.3 g crude protein/ Mcal or low (L), were formulated and supplemented with or without enzyme. Diets were given in four feeding programs, i.e. , H-M-L, H-M-M, M-M-L, and M-L-L during the starter (1-28 d), grower (29-56 d), and finisher (57-84 d) periods, respectively. Each treatment was replicated five times. Bodyweight gain (BWG), feed intake, and FCR were measured each period. At the end of the trial, carcass yield and internal organs were measured. Results of the experiment (1-84 d period) showed that the feed intake was significantly affected by ND. Chickens fed the H-M-L diets have the highest feed intake, while the lowest was found in chickens fed M-M-L diets. A significant interaction was found in the FCR. The best FCR was found in chickens fed the H-M-M diets without enzymes, but the best FCR was found on the M-M-L diets with enzymes. Livability, carcass yield, abdominal fat, liver, proventriculus, and gizzard weights were not affected by the treatments. The jejunum sizes of chickens were significantly longer when fed the low-density diet than those fed the higher nutrient density diet. The ileum sizes of chickens were significantly shorter than chickens fed the diet without enzymes. The highest income over feed cost was achieved when chickens were fed the M-M-L diets supplemented with enzymes. It is concluded that the best performance of growing KUB chickens was obtained when fed M-M-L diets supplemented with BS4 enzymes (30 Units of saccharification/kg diet) and when fed H-M-M diets without enzyme supplementation.

Soybean meal and yellow corn are conventional feedstuffs used as the main ingredients in poultry feeds due to their high nutrients availability. On the other hand, these two feedstuffs are high in demand by other animals (soybean meal) and humans (yellow corn). By the year 2050, the world’s population is expected to increase up to 9.1 billion. Global consumption of poultry products, such as meat or eggs is increasing predominantly in developing countries. Consequently, the global demand for poultry feedstuffs would increase. The availability of feedstuffs for poultry nutrition nowadays is becoming more competitive. Thus, food security, especially in the developing countries, would be threatened. Currently, efforts are being made to use alternative feedstuffs to substitute portion of soybean meal and yellow corn in poultry diets. This chapter discusses the alternative feedstuffs that can be incorporated in poultry feeds. In addition, the nutritive content and availability are examined as well as how to improve the nutritive quality of such nontraditional feedstuffs.
