Limited studies on evaluation of the nutritive value of sugar beet seed (Beta vulgaris ) waste (SBSW) and its application in beef or lamb production have been carried out in its producing countries. SBSW is one of the side products of sugar beet seed which approximately a quarter of seeds can not be used in cultivation and is considered as waste. Consisting of 17% whole seeds and the rest as cracked seeds or hulls, SBSW contains 14.5, 32.5, 1.3, 16.9, 27.5, 39 and 49.9 percent CP, CF, EE, NFE, CF, Ash, ADF and NDF respectively. Also, SBSW contains 3.20 Mcalkg-1 Potkanski and Urbaniak (1985) reported an improved average daily gain (ADG) and feed conversion ratio (FCR) in comparison to wheat straw because of its better essential amino acid index, which is close to wheat grain, but there is no report on its effects on fat tail composition. This trial was performed to examine SBSW replacement effects in fattening Chal lamb rations.

Sixteen blocks of eight littermate pigs were weaned at 3 weeks of age and each divided into four groups. Various levels of nutrition were applied to the pigs so that the four groups reached 20 kg. at 59, 68, 80 and 91 days of age, respectively.Only small differences were observed between groups in feed conversion ratio to 20 kg.; however, Group 4 required more feed per kg. gain than the three other groups.During the second period (20–90 kg.) the pigs in each group were divided into two sub-groups, which were on a high and a low plane of nutrition respectively. In both sub-groups the type of feeding before 20 kg. influenced the average daily gain and feed conversion ratio. The older the pigs were at 20 kg. the higher the daily gain and the lower the feed conversion ratio in the following period. There was an increase in daily feed intake with increased age at 20 kg. for pigs fed ad lib. during the second period.An increase in age at 20 kg. caused a significant decrease in thickness of backfat, a greater area of eye muscle and a smaller area of fat overlying muscle. For pigs fed ad lib. the area of eye muscle was significantly increased by a higher age at 20 kg. live-weight.

Abstract(An experiment with two groups of East Balkan pigs – castrated males (n=10) and females (n=10), was carried out to study the growth performance and fattening abilities of the animals from the weaning until slaughter. The pigs were included in the trial at 60 day age. The average live weight of the castrated males was 8. 65±1.08 kg and for the females, 8.5±0.62 kg.The pigs were reared using traditional technology, grazing on natural pastures in the Strandzha mountain, Bulgaria. In autumn, acorns were naturally present in their diet. According to the category, the animals additionally received ground organic feed (50% barley and 50% wheat). The trial lasted 304 days (from February to November, 2019). During this period the final live weight of the male castrated pigs reached 88.00 kg while that of the females was 84.4 kg. The difference, however, was not significant. Furthermore, no significant differences in the growth performance characteristics that could be attributed to the sex of the animals were observed. The average daily gain of both sexes tended to be lower in summer and higher in autumn. The feed conversion ratio was higher in summer. The animals showed high average daily weight gain at pasture when their live weight was over 50 kg.

Abstract Improved genetics in commercial pig production have resulted in larger litter sizes. However this has increased the prevalence of compromised pigs exhibiting inferior birthweights, weaning weights, and lifetime performance. This study aimed to determine the effects of increased sow lactation feed intake on growth of low and average birthweight piglets until 10 wk of age. Low (Low BW; &lt;1 kg) and average (Av BW; 1.3–1.7 kg) birthweight animals were reared in uniformly weighted litters comprising 14 piglets on a foster mother offered either a low (Low FA; max 7.5 kg/d) or high (High FA; max 11 kg/d) feed allowance over a 28- ± 1-d lactation. Piglet performance was monitored from birth until 10 wk of age. Sows offered a High FA consumed 42.4 kg more feed on average than those offered Low FA, resulting in a greater derived milk yield (P &lt; 0.05). Animals of Av BW remained heavier than Low BW pigs throughout the trial (P &lt; 0.05). Piglets reared by High FA sows were heavier at weeks 3, 4, 5, and 7 (P &lt; 0.05) but not week 10 (P &gt; 0.05). Growth rate of piglets relative to their birthweight was significantly greater for Low BW piglets than those of Av BW during lactation (P &lt; 0.001). Piglets reared by sows offered a High FA expressed greater relative growth preweaning (P &lt; 0.05); however, postweaning relative growth for piglets reared on sows offered a Low FA was greater (P &lt; 0.05) suggesting compensatory growth. Neither birthweight nor sow feed allowance significantly affected preweaning mortality (P &gt; 0.05). However, Low BW animals on sows with a High FA recorded half the preweaning mortality of Low BW pigs on sows with a Low FA. During week 1 of lactation, Av BW litters recorded a greater total suckling duration compared to Low BW litters (P &lt; 0.05) but there was no difference in suckling frequency (P &gt; 0.05). During week 3 of lactation, High FA litters displayed a significantly lower suckling frequency (P &lt; 0.05) yet a greater total suckling duration (P &lt; 0.001). Average daily gain was greater for Av BW pigs during weeks 4–7 (P &lt; 0.001) but no difference was recorded between weeks 7 and 10 (P &gt; 0.05). Average daily feed intake was greater for Av BW pigs throughout the nursery period (P &lt; 0.05) but feed–conversion ratio did not differ compared to Low BW pens (P&gt;0.05). In conclusion, offering sows a High FA increased weaning weight of all animals; however, birthweight was the major determinant of postweaning performance.

Canola meal (CM) is a locally produced protein source that may be less expensive than soybean meal (SBM). This study evaluated the effects of replacing 0%, 25%, 50%, 75%, and 100% SBM with CM in diets for slaughter ostriches. The CM was added at the expense of SBM and other concentrates, with minor changes in other ingredients. Birds (n = 15 per treatment) were reared from 77 to 337 days old on the trial diets, which were supplied ad libitum for starter, grower, and finisher phases. Bodyweights and feed intake were measured during these phases. No differences (P >0.05) were found between treatments for live weight at the end of each phase, dry matter intake (DMI), average daily gain (ADG) and feed conversion ratio (FCR) over all the growth phases. Although no differences were observed in live weight at the end of each phase, the birds reared on the diet with 50% CM were heaviest at slaughter, and birds reared with 100% CM were lightest (P <0.05). Differences (P <0.05) between diets were observed for the weight at slaughter, weights of the liver and thyroid glands and the pH of the cold carcass. However, no differences (P >0.05) were observed between diets for fat pad weight, dressing percentage, and weights of thighs and Muscularis gastrocnemius. The results indicate that CM could replace SBM in the diets of slaughter ostriches without affecting production traits and slaughter yields.Keywords: alternative protein, average daily gain, canola, dry matter intake, feed conversion ratio, growth, ostrich nutrition, production

In 3 experiments each of 4 treatments, crossbred pigs about 35 kg were given basal diets with a low concentration of 1 amino acid and DL methionine 0, 0.41 or 0.82 and 1.23, L-threonine 0, 0.5, 1.0 and 1.5 and DL-tryptophan 0, 0.31, 0.62 and 0.93 g/kg. Apparent faecal digestibility of organic matter, protein and amino acids of 1 or 2 diets from each feeding experiment was estimated with 4 pigs each. Average daily gain of the optimally supplemented groups was 875 g and feed conversion ratio 2.84. For maximum growth performance of pigs between 35 and 105 kg, the requirement for total methionine + cystine, threonine and tryptophan, relative to total lysine supply, was about 60, 66 and 19%, respectively. On a faecal digestible basis, requirements were about 58, 63 and 19%, relative to faecal digestible lysine, respectively. (Abstract retrieved from CAB Abstracts by CABI’s permission)

Sets of twin lambs from both sexes representing 11 genetic groups were fed either concentrate (HE) or roughage (LE) diets from weaning to 32 kg liveweight. One lamb from each set received the HE diet while the other received the LE diet. Data on average daily gain (ADG), relative ADG (RADG) and feed conversion ratio (FCR) were analyzed to test for the presence of a genotype × diet interaction; this effect was significant for RADG. Although the ranking of the genetic groups with respect to RADG depended upon diet, the group ranking highest on HE was also the highest on LE. The set of twins × diet interaction was not significant for ADG or RADG. The results support the present practice in test stations of feeding lambs concentrate rations to identify their potential for growth and basing growth comparisons on a within genetic group basis. Key words: Genotype × diet interaction, growth rate, feed conversion ratio

Twenty barrow and twenty gilt Berkshire x Large White pigs were fed barley based diets containing protein supplements of either 13 per cent soybean meal, 9 per cent fishmeal, 14.5 per cent safflower meal plus 0.2 per cent I-lysine mono hydrochloride plus 0.1 per cent methionine or 14.5 per cent safflower meal plus 4.5 per cent fishmeal from 46.4 to 87.0 kg liveweight. All diets were fed individually at a restricted feeding scale. The safflower meal diets were also fed ad libitum. Barrows and gilts fed ad libitum recorded a 65 and 27 per cent improvement respectively in average daily gain and had slightly fatter carcases than those fed comparable diets restrictively. Feed conversion ratio was not significantly affected by level of feeding. Growth and carcase attributes of pigs fed diets restrictively were similar apart from the feed conversion ratio of pigs fed the amino acid supplemented safflower meal diet, which was inferior (P < 0.05) to those fed the soybean meal supplemented diets. Barrows grew faster and produced fatter carcases than gilts, A significant sex x diet interaction occurred from which it was concluded that gilts, but not barrows, could be fed ad libitum without detriment to the quality of the carcase.

The purpose of this study was to test and evaluate feed intake, average daily gain and feed conversion ratio of male and female broilers with a separate maintenance treatment (sexing) in semi-closed house cages. The study was conducted at Joni Farm, Tegineneng Subdistrict, Pesawaran District. The type of research used was experimental research comparing the performance of male and female broilers that were kept separately (sexing) at the age of 12 days to 30 days. Experimental broilers used during research were 94 male and 94 female Lohmann. The variables observed in this study were male and female broiler on feed intake, average daily gain (ADG) and Feed Convertion Ratio (FCR). Based on the results of statistical analysis showed sexing has a significant effect on ADG and FCR. Sexing had no effect on feed intake. The average feed intake of male broiler chicken feed was 128.12 grams, while the consumption of female broiler was 120.00 grams. Average daily gain (ADG) of male broiler was higher than female broiler , ADG male broiler were 75.61 grams, while ADG female broiler were 66.28 grams. FCR of female broilers was 1.77 wich higher than male broilers was 1.57. Keywords: Average Daily Gain, Feed Convertion, Feed Intake, Sexing Chicken Broiler
